Continuous use of traditional instruction has proven to give results of unsatisfactory performance, misconceptions and poor attitudes towards chemistry for most students. This study was designed to examine the differential effects of multimodal instructional and traditional instructional approaches on selected Colleges of Education students’ understanding of chemistry topics to remove the drawbacks of the traditional instructional methods used to teach Chemistry. The sample of the study involved 120 students who were randomly selected into groups from two colleges of Education. The primary data was collected from interview, questionnaire and pre and post-tests for the study. The results indicated that most of students who participated in the study had difficulties learning Chemistry concepts, hold a lot of misconceptions and negative attitudes and interest in learning the topics of the subject. The difficulties were attributed to the sort of instructional approach used to teach Chemistry. Multimodal instructional approaches were proven to show positive significant effect on students’ learning chemistry in the Colleges. There was high improvement in the performance and interest of students to learn Chemistry concepts. The students who were taught by multimodal instructional approaches could interpret and comprehend more chemistry concepts in the study than those who were taught by traditional instructional approach.
Effects of Inquiry-Based Learning Strategies on Chemistry Students’ Conceptio...AJHSSR Journal
The study identified Senior Secondary School II (SS2) students’ misconceptions and determined
the effect of inquiry-based learning strategies: Investigate Discuss (ID), Predict-Discuss-Investigate-Discuss
(PDID) and Teacher Demonstration (TD) on students’ conceptual knowledge at macroscopic, microscopic and
symbolic levels in chemical kinetics and equilibrium. The pre-test post-test quasi experimental control group
design as adopted. 359 SS2 chemistry students were randomly sampled from nine public schools in Lagos
States, Nigeria. The validated Conceptual Knowledge Test (CKT) was easy test, structured to reflect the three
levels of conceptual knowledge was the major instrument for the study. There were operational guides for the
learning strategies which comprised eight practical activities that had same contents but different procedural
steps in their implementations. The mean, simple percentage and bar chat were used in analysing students
responses to pre-test and post-test of CKT. The study identified the students’ misconceptions in chemical
kinetics and equilibrium. The results indicated that the ID followed by the PDID was more effective in
promoting conceptual knowledge of microscopic and symbolic levels in chemical kinetics and equilibrium. The
ID and PDID learning strategies are recommended for chemistry teaching to improve students’ achievement in
conceptual knowledge at microscopic and symbolic levels of content representations in chemistry
The impacts of a technology-integrated formative assessment technique on
students' conceptual and procedural knowledge in studying chemical
equilibrium are studied in this study. To attain the purpose, a quasiexperimental
pretest-posttest strategy nested with a
qualitative study method was
adopted. The study has three groups: two experimental and one
comparative. A random sample strategy was utilized to select two intact
classes for treatment and one intact class for comparison groups. Data was
collected using the chemical equilibrium conceptual test, the procedural test,
and classroom observation. The data was examined using descriptive (mean
and standard deviation) and inferential statistics (one-way ANOVA, oneway
MANOVA,
and
Pearson
product
moment
correlation).
According
to
the
findings, technology-integrated
formative assessment processes
outperformed traditional techniques and formative assessment strategies
alone in enhancing students' conceptual and practical understanding of
chemical equilibrium. Similarly, when technology-integrated formative
assessment processes are used, classroom observations show that students
have a strong motivation to learn and that the instructor is more skilled than
the other two teachers. Technology-integrated formative assessment
processes were shown to be more effective than the other two groups in
promoting students' conceptual and procedural understanding when learning
chemical equilibrium.

Chemistry Students Assessment of Their Chemistry Teachers Usage of Ncce Pedag...iosrjce
This study assessed the students’ assessment of their chemistry teachers’ usage of the eleven
pedagogical methods in the National Commission for Colleges of Education (NCCE) benchmark. It also
assessed the influence of college ownership and gender on the usage. The study was carried out in Federal and
State owned Colleges in the five States in South-East zone of Nigeria. The sample for the study comprises of two
hundred (200) final year chemistry students drawn from the seven Colleges in the five States in the zone. Three
research quests and three hypotheses guided the study. 55-item questionnaire constructed by the researcher
from the eleven pedagogical methods in the Benchmark was used as instrument for data collection. This
instrument was validated by experts in the field and reliability sought and established using Cronbach alph
technique and was found to be 87. Data collected were analysed using means and standard deviation for
research questions and independent t-test for hypotheses at 0.05 level of confidence. The results obtained
showed that out of eleven methods only four (demonstration experimental, discussion and lecture methods) were
used regularities by teachers during classroom instructions. All other seven methods were not adequately used.
Gender and college ownership have no remarkable influence on the usage of these methods. Recommendation
for the usage of all the methods was made
Evaluation of Agro-morphological Performances of Hybrid Varieties of Chili Pe...Premier Publishers
In Benin, chilli pepper is a widely consumed as vegetable whose production requires the use of performant varieties. This work assessed, at Parakou and Malanville, the performance of six F1 hybrids of chilli including five imported (Laali, Laser, Nandi, Kranti, Nandita) and one local (De cayenne), in completely randomized block design at four replications and 15 plants per elementary plot. Agro-morphological data were collected and submitted to analysis of variance and factor analysis of mixed data. The results showed the effects of variety, location and their interactions were highly significant for most of the growth, earliness and yield traits. Imported hybrid varieties showed the best performances compared to the local one. Multivariate analysis revealed that 'De cayenne' was earlier, short in size, thin-stemmed, red fruits and less yielding (≈ 1 t.ha-1). The imported hybrids LaaliF1 and KrantiF1 were of strong vegetative vigor, more yielding (> 6 t.ha-1) by developing larger, long and hard fruits. Other hybrids showed intermediate performances. This study highlighted the importance of imported hybrids in improving yield and preservation of chili fruits. However, stability and adaptation analyses to local conditions are necessary for their adoption.
An Empirical Approach for the Variation in Capital Market Price Changes Premier Publishers
The chances of an investor in the stock market depends mainly on some certain decisions in respect to equilibrium prices, which is the condition of a system competing favorably and effectively. This paper considered a stochastic model which was latter transformed to non-linear ordinary differential equation where stock volatility was used as a key parameter. The analytical solution was obtained which determined the equilibrium prices. A theorem was developed and proved to show that the proposed mathematical model follows a normal distribution since it has a symmetric property. Finally, graphical results were presented and the effects of the relevant parameters were discussed.

Chia is an emerging cash crop in Kenya and its production is inhibited by lack of agronomic management information. A field experiment was conducted in February-June and May-August 2021, to determine the influence of nitrogen and spacing on growth and yield of Chia. A randomized complete block design with a split plot arrangement was used with four nitrogen rates as the main plots (0, 40, 80, 120 kg N ha-1) and three spacing (30 cm x 15 cm (s1), 30 cm x 30 cm (s2), 50 cm x 50 cm (s3)). Application of 120 kg N ha-1 significantly increased (p≤0.05) vegetative growth and seed yield of Chia. Stem height, branches, stem diameter and leaves increased by 23-28%, 11-13%, 43-55% and 59-88% respectively. Spacing s3 significantly increased (p≤0.05) vegetative growth. An increase of 27-74%, 36-45% and 73-107% was recorded in number of leaves, stem diameter and dry weight, respectively. Chia yield per plant was significantly higher (p≤0.05) in s3. However, when expressed per unit area, s1 significantly produced higher yields. The study recommends 120 kg N ha-1 or higher nitrogen rates and a closer spacing of 15 cm x 30 cm as the best option for Chia production in Kenya.
Enhancing Social Capital During the Pandemic: A Case of the Rural Women in Bu...Premier Publishers
Social capital plays an essential role in empowering people for social and economic change even during the pandemic. A livelihood project of the government was implemented among the members of a women’s association of a disadvantaged upland community in Bukidnon province, Southern Philippines for inclusive development. This study was conducted to determine the influence of some socio-economic attributes and the change in the knowledge level on the social capital of the rural women amidst the pandemic. The activities of the project were implemented considering the health protocols imposed by the government during the health crisis. The findings revealed that the trainings conducted resulted to a positive change in the knowledge level among the rural women. This facilitated the production of vegetables for their households and generated additional income very necessary during the pandemic especially that other economic activities were hindered. Similarly, there was a significant increase in the social capital of the rural women during the last two years. The main occupation, sources of income and their ethnicity significantly influenced the social capital of the rural women. The rural development workers and policymakers must consider the social capital of the group in the implementation of poverty alleviation programs.
Impact of Provision of Litigation Supports through Forensic Investigations on...Premier Publishers
This paper presents an argument through the fraud triangle theory that the provision of litigation supports through forensic audits and investigations in relation to corporate fraud cases is adequate for effective prosecution of perpetrators as well as corporate fraud prevention. To support this argument, this study operationalized provision of litigation supports through forensic audit and investigations, data mining for trends and patterns, and fraud data collection and preparation. A sample of 500 respondents was drawn from the population of professional accountants and legal practitioners in Nigeria. Questionnaire was used as the instrument for data collection and this was mailed to the respective respondents. Resulting responses were analyzed using the OLS multiple regression techniques via the SPSS statistical software. The results reveal that the provision of litigation supports through forensic audits and investigations, fraud data mining for trends and patterns and fraud data collection and preparation for court proceedings have a positive and significant impact on corporate fraud prevention in Nigeria. This study therefore recommends that regulators should promote the provision of litigation supports through forensic audits and investigations in relation to corporate fraud cases in publicly listed firms in Nigeria, as this will help provide reports that are acceptable in court proceedings.
Improving the Efficiency of Ratio Estimators by Calibration WeightingsPremier Publishers
It is observed that the performances of most improved ratio estimators depend on some optimality conditions that need to be satisfied to guarantee better estimator. This paper develops a new approach to ratio estimation that produces a more efficient class of ratio estimators that do not depend on any optimality conditions for optimum performance using calibration weightings. The relative performances of the proposed calibration ratio estimators are compared with a corresponding global [Generalized Regression (GREG)] estimator. Results of analysis showed that the proposed calibration ratio estimators are substantially superior to the traditional GREG-estimator with relatively small bias, mean square error, average length of confidence interval and coverage probability. In general, the proposed calibration ratio estimators are more efficient than all existing estimators considered in the study.
Urban Liveability in the Context of Sustainable Development: A Perspective fr...Premier Publishers
Urbanization and quality of urban life are mutually related and however it varies geographically and regionally. With unprecedented growth of urban centres, challenge against urban development is more in terms of how to enhance quality of urban life and liveability. Making sense of and measuring urban liveability of urban places has become a crucial step in the context of sustainable development paradigm. Geographical regions depict variations in nature of urban development and consequently level of urban liveability. The coastal regain of West Bengal faces unusual challenges caused by increasing urbanization, uncontrolled growth, and expansion of economic activities like tourism and changing environmental quality. The present study offers a perspective on urban liveability of urban places located in coastal region comprising of Purba Medinipur and South 24 Parganas districts. The study uses the liveability standards covering four major pillars- institutional, social, economic and physical and their indicators. This leads to develop a City Liveability Index to rank urban places of the region, higher the index values better the urban liveability. The data for the purpose is collected from various secondary sources. Study finds that the eastern coastal region of the country covering state of West Bengal depicts variations in index of liveability determined by physical, economic, social and institutional indicators.
Transcript Level of Genes Involved in “Rebaudioside A” Biosynthesis Pathway u...Premier Publishers
Stevia rebaudiana Bertoni is a plant which has recently been used widely as a sweetener. This medicinal plant has some components such as diterpenoid glycosides called steviol glycosides [SGs]. Rebaudioside A is a diterpenoid steviol glycoside which is 300 times sweeter than table sugar. This study was done to investigate the effect of GA3 (50 mg/L) on the expression of 14 genes involved in Rebaudioside A biosynthesis pathway in Stevia rebaudiana under in vitro conditions. The expression of DXS remarkably decreased by day 3. Also, probably because of the negative feedback of GA3 on MEP-drived isoprenes, GGDS transcript level reached its lowest amount after GA3 treatment. The abundance of DXR, CMS, CMK, MCS, and CDPS transcripts showed a significant increase at various days after this treatment. A significant drop in the expression levels of KS and UGT85C2 is detected during the first day. However, expression changes of HDR and KD were not remarkable. Results revealed that the level of transcript of UGT74G1 and UGT76G1 up regulated significantly 4 and 2 times higher than control, respectively. However, more research needs to shed more light on the mechanism of GA3 on gene expression of MEP pathway.

Information on genetic variability for biochemical characters is a prerequisite for improvement of tea quality. Thirteen introduced tea clones characterized with objective; assessing tea clones based on morphological characters at Melko and Gera research stations. The study was conducted during 2017/18 cropping season on experimental plots in RCBD with three replications. Data recorded on morphological traits like days from pruning to harvest, height to first branch, stem diameter, leaf serration density, leaf length, leaf width, leaf size, petiole length, leaf ratio, internode length, shoot length, number of shoot, canopy diameter, hundred shoot weight, fresh leaf yield per tree. Cluster analysis of morphological trait grouped into four clusters indicated, the existence of divergence among the tested clones. The maximum inter-cluster distance was between clusters I and IV (35.27) while the minimum inter cluster distance was observed between clusters I and II (7.8).Principal components analysis showed that the first five principal components with eigenvalues greater than one accounted 86.45% for 15 morphological traits. Generally, the study indicated presence of variability for several morphological traits. However, high morphological variation between clones is not a guarantee for a high genetic variation; therefore, molecular studies need to be considered as complementary to biochemical studies.
Causes, Consequences and Remedies of Juvenile Delinquency in the Context of S...Premier Publishers
This research work was designed to examine nature of juvenile offences committed by juveniles, causes of juvenile delinquency, consequences of juvenile delinquency and remedies for juvenile delinquency in the context of Sub-Saharan Africa with specific reference to Eritrea. Left unchecked, juvenile delinquents on the streets engage in petty theft, take alcohol or drugs, rape women, rob people at night involve themselves in criminal gangs and threaten the public at night. To shed light on the problem of juvenile delinquency in the Sub-Saharan region data was collected through primary and secondary sources. A sample size of 70 juvenile delinquents was selected from among 112 juvenile delinquents in remand at the Asmara Juvenile Rehabilitation Center in the Eritrean capital. The study was carried out through coded self-administered questionnaires administered to a sample of 70 juvenile delinquents. The survey evidence indicates that the majority of the juvenile respondents come either from families constructed by unmarried couples or separated or divorced parents where largely the father is missing in the home or dead. The findings also indicate that children born out of wedlock, families led by single mothers, lack of fatherly role models, poor parental-child relationships and negative peer group influence as dominant causes of juvenile infractions. The implication is that broken and stressed families are highly likely to be the breeding grounds for juvenile delinquency. The survey evidence indicates that stealing, truancy or absenteeism from school, rowdy or unruly behavior at school, free-riding in public transportation, damaging the book of fellow students and beating other young persons are the most common forms of juvenile offenses. It is therefore, recommended that parents and guardians should exercise proper parental supervision and give adequate care to transmit positive societal values to children. In addition, the government, the police, prosecution and courts, non-government organizations, parents, teachers, religious leaders, education administrators and other stakeholders should develop a child justice system that strives to prevent children from entering deeper into the criminal justice process.

Stigma and discrimination associated with mental illness are a common occurrence in the Sub-Saharan region including Eritrea. Numerous studies from Sub-Saharan Africa suggest that stigma and discrimination are major problems in the community, with negative attitudes and behavior towards people with mental illness being widespread. In order to assess the whether such negative attitudes persist in the context of Eritrea this study explored the knowledge and perceptions of 90 Eritrean university students at the College of Business and Economics, the University of Asmara regarding the causes and remedies of mental illness A qualitative method involving coded self-administered questionnaires administered to a sample of 90 university students to collecting data at the end of 2019. The survey evidence points that almost 50% of the respondents had contact with a mentally ill person suggesting that the significant number of the respondents experienced a first-hand encounter and knowledge of mental illness in their family and community. The findings show an overall greater science-based understanding of the causes of mental illness to be followed by recommended psychiatric treatments. The survey evidence indicates that the top three leading causes of mental illness in the context of Eritrea according to the respondents are brain disease (76%), bad events in the life of the mentally ill person (66%) and substance abuse or alcohol taking, smoking, taking drugs like hashish. (54%). The majority of the respondents have a very sympathetic and positive outlook towards mentally ill persons suggesting that mentally illness does not simply affect a chosen individual rather it can happen to anybody regardless of economic class, social status, ethnicity race and religion. Medical interventions cited by the majority of the respondents as being effective treatments for mental illness centered on the idea that hospitals and clinics for treatment and even cures for psychiatric disease. Changing perceptions of mental illnesses in Eritrea that paralleled the very caring and sympathetic attitudes of the sample university students would require raising public awareness regarding mental illness through education, using the mass media to raise public awareness, integrating mental health into the primary health care system, decentralizing mental health care services to increase access to treatment and providing affordable service to maintain positive treatment outcomes.
Effect of Phosphorus and Zinc on the Growth, Nodulation and Yield of Soybean ...Premier Publishers
An investigation was carried out at Kogi State University Student Research and Demonstration farm Anyigba during the 2019 wet season to observe the effect of phosphorus and zinc on the growth, nodulation and yield of soybean. The treatments comprised three levels: phosphorus and zinc (0, 30 and 60 kg P2O5/ha; 0, 5 and 10kg Zn/ha) and two varieties TGX 536 – 02D and Samsoy 2. The investigation revealed that application of phosphorus affected growth, nodulation, yield and some yield components of soybean while zinc application, apart from the plant height, which is reduced significantly, had no significant effect on other growth characters, nodulation, yield and yield components. However, it was generally found to decrease most of the characters. Application of 60 kg P2O5/ha gave the highest growth and yield, while 30 kg P2O5/ha gave the highest nodulation. Application of 60 kg P2O5/ha significantly increased yield to 1.9t/ha, which was significantly higher over the control plots, which gave 1.7t/ha. Crude protein and oil contents of the seeds were not significantly affected by phosphorus application but were significantly affected by zinc application, which significantly decreased protein content as its amount an increase from 0 to 10 kg/ha, and significantly increased oil content from 0 to 5kg/ha and decreased it below 5kg/ha. It was also revealed that the two varieties responded similarly to phosphorus and zinc in terms of growth, grain yield and crude protein content of the seeds.

A field experiment was conducted at Adami Tullu Agricultural Research Center in 2018 under rainfed condition with supplementary irrigation to determine the influence of harvest stage on vine yield and tuberous root yield of orange fleshed sweet potato varieties. The experiment consisted of four harvest stages (105, 120, 135 and 150 days after planting) and Kulfo, Tulla and Guntute varieties. A 4 X 3 factorial experiment arranged in randomized complete block design with three replications was used. Interaction of harvest stage and variety significantly influenced above ground fresh biomass, vine length, marketable tuberous root weight per hectare, commercial harvest index and harvest index. The highest mean values of above ground fresh biomass (66.12 t/ha) and marketable tuberous root weight (56.39 t/ha) were produced by Guntute variety harvested at 135 days after planting. Based on the results, it can be recommended that, farmers of the study area can grow Guntute variety by harvesting at 135 days after planting to obtain optimum vine and tuberous root yields.
Performance evaluation of upland rice (Oryza sativa L.) and variability study...Premier Publishers
This study aimed at assessing genetic variability and to evaluate the performance of 13 improved upland rice varieties for yield and its components based on morphological traits. The field experiment was conducted using a randomized block design at Guraferda and Gimbo districts in the 2019 main cropping season. The analysis of variance (ANOVA) over the two locations revealed significant differences (p≤ 0.05) among varieties for days to 50% heading, days to 85% maturity, panicle length, thousand-grain weight, and grain yield. Similarly, the ANOVA for variety by location interactions depicted significant differences among the tested varieties for days to 50% heading, days to 85% maturity, and thousand-grain weight. High heritability was obtained from days to heading (88.5%), panicle length (85.0%), and grain yield (85.2%), which indicates these traits can be easily improved through selection. High to medium broad sense heritability and genetic advance as percentage of the mean for days to heading, thousand-grain weight, and grain yield indicates a good opportunity for improvement through selection using their phenotypic performance. This is mainly due to the high role of additive gene action in the expression of such traits. This study confirmed the presence of variability among varieties for most of the studied traits, which will create an opportunity for breeders to improve rice yield and other attributes.

This study was conducted at Enchete kebele in Benna-Tsemay Woreda, South Omo Zone to evaluate the response of hot pepper to deficit irrigation on yield and water productivity under furrow irrigation system. The experiment comprised four treatments (100 % of ETc, 85% of ETc, 70 % of ETc and 50% of ETc), respectively. The experiment was laid out in RCBD and replicated four times. The two years combined yield results indicated that, the maximum total yield (20.38 t/ha) was obtained from 100% ETc while minimum yield (12.92 t/ha) was obtained from 50% of ETc deficit irrigation level. The highest WUE 5.22 kg/ha mm-1 was obtained from 50% of ETc. Treatment of 100% ETc irrigation application had highest benefit cost ratio (4.5) than all others treatments. Applying 50% of ETc reduce the yield by 37% when compared to 100 % ETc. Accordingly, to achieve maximum hot pepper yield in areas where water is not scarce, applying 100% ETc irrigation water application level throughout whole growing season under furrow irrigation system is recommended. But, in the study area water scarcity is the major limiting factor for crop production. So, it is possible to get better yield and water productivity of hot pepper when we apply 85% ETc irrigation water throughout growing season under furrow irrigation system.
Harnessing the Power of Agricultural Waste: A Study of Sabo Market, Ikorodu, ...Premier Publishers
Nigeria is still burdened with huge responsibilities of waste disposal because the potential for benefits of proper waste management is yet to be harnessed. The paper evaluates the capacity of the Sabo Cattle market in producing the required quantities of waste from animal dung alongside decomposed fruits with a view to generating renewable energy possibilities for lighting, security and other business activities of the market. It is estimated that about 998 million tons of agricultural waste is produced yearly in the country with organic wastes amounting to 80 percent of the total solid wastes. This can be categorized into biodegradable and non-biodegradable wastes. The paper evaluates the capacity of the Sabo Cattle market in producing the required quantities of waste from animal dung alongside decomposed fruits with a view to generating renewable energy possibilities for lighting, security and other business activities of the market. The Sabo market was treated as a study case with the adoption of in-depth examinations of the facility, animals and products for sale and waste generated. A combination of experimental, interviews (qualitative) and design simulation (for final phase) was adopted to extract, verify and analyse the data generated from the study. Animal waste samples were subjected to compositional and fibre analysis with results showing that the sample has high potency for biogas production. Biodegradable Wastes are human and animal excreta, agricultural and all degradable wastes. Availability of high quantity of waste generated being organic in Sabo market allows the use of anaerobic digestion to be proposed as a waste to energy technology due to its feasibility for conversion of moist biodegradable wastes into biogas. The study found that at peak supply period during the Islamic festivities, a conservative 300tonnes of animal waste is generated during the week which translates to over 800kilowatts of electricity.

The general purpose of this study is to investigate the influence of conferences and job rotation on job productivity of library staff in tertiary institutions in Imo State, Nigeria. The survey research design was used for this study using questionnaire as an instrument for data collection. This study covered the entire population of 661. Out of these, 501 copies of the questionnaire representing 75.8% were duly completed and returned for analysis. Student’s t-test was used to analyze the research questions. The finding showed that conferences had no significant influence on the job productivity of library staff in tertiary institutions in Imo State, Nigeria (F cal= 7.86; t-vale =6.177; p >0.005). Finding also showed that job rotation significantly influences job productivity of library staff in tertiary institutions in Imo State, Nigeria (F-cal value= 18.65; t-value = 16.225; P<0.05). This study recommended that, government should ensure that library staff participate in conferences with themes and topics that are relevant to the job they perform and also ensure that there should be proper evaluation and feedback mechanism which aimed to ensuring control and minimize abuse of their development opportunities. Again, there should be written statement of objectives in order to sustain job rotation programmes. Also, that training and development needs of library staff must be identified and analyzed before embarking on job rotation processes as this would help to build skills, competences, specialization and high job productivity.

Microscopic examination of urine samples collected from geriatric dogs revealed increased numbers of erythrocytes, leucocytes, epithelial cells and pus cells along with casts, bacteria, spermatozoa and crystals of various shapes. Among the different crystals, triple phosphate or struvite were predominant, followed by calcium oxalate dihydrate, calcium oxalate monohydrate and ammonium urate or biurate. The struvite crystals were, coffin-lid shape and while calcium oxalate dihydrate were octahedron or envelope and monohydrate crystals demonstrated “picket fence” and “dumbbell” and “hemp seed” appearance. Brown or yellow-brown spherical bodies with irregular borders with thorn-apple appearance were shown by ammonium urate or biurate crystals. SEM aspects of magnesium ammonium phosphate crystals revealed perpendicular columnar strata, few with scattered hexa or octa-hedral coffin-lid shaped crystals and calcium phosphate crystals were like cracked eggshells. Presence of wavy phases with sundry areas (uric acid), picket fence (calcium oxalate monohydrate) and typical envelope (calcium oxalate dehydrate) were electron microscopic appearance of various crystals.
Gentrification and its Effects on Minority Communities – A Comparative Case S...Premier Publishers
This paper does a comparative analysis of four global cities and their minority districts which have been experiencing the same structural pressure of gentrification. The main contribution of this paper is providing a detailed comparison of four micro geographies worldwide and the impacts of gentrification on them: Barrio Logan in San Diego, Bo-Kaap in Cape Town, the Mission District in San Francisco, and the Rudolfsheim-Fünfhaus District in Vienna. All four cities have been experiencing the displacement of minority communities due to increases in property values. These cities were chosen because their governments enacted different policies to temper the gentrification process. It was found that cities which implemented social housing and cultural inclusionary policies were more successful in maintaining the cultural and demographic make-up of the districts.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2. Effect of Mnemonic and Teaching of Oxidation and Reduction Reactions to Secondary School Chemistry Students

On this basis, it is reasonable to assume that all students
need a certain level of scientific knowledge and related
skills in order to become scientifically literate citizens and,
thus, to be able to participate in dialectical socio-scientific
discussions, debates, and decision-making processes.
This is especially important in our increasingly
technological world (Hofstein, Eilks, and Bybee, (2011). In
addition, this claim supports the idea of making science
education more effective and relevant.
In as much as chemistry education and Chemistry is
important, Nigerian students have had a persistence low
performance in Chemistry examination both in internal and
external examinations. Sakiyo and Badau (2015)
conducted a research on chemistry performance of
students in WASSC that had credit pass and obtained the
following results: 44.44%, 43.69%, 50.70%, 49.54%, and
43.13% for 2008, 2009, 2010, 2011 and 2012 respectively.
From the above result, it is clear that there is a marginal
decline in students’ academic performance in Chemistry.
This kind of performance shows that learning chemistry is
not fun rather students are running away from it.
Various factors have been attributed to students’
consistent abysmal performance in school science and
mathematics subjects especially chemistry at the senior
secondary level Chief among the contributing factors being
the approaches used by chemistry teachers which tend to
make chemistry concepts to be too abstract and
uninteresting to students as well as the general perception
of chemistry topics by students ..Another being that
chemistry is generally perceived difficult to learn by
students. Thus most often, students tend to view concepts
in chemistry as being too volatile as they often are unable
to remember them (Jimoh,(2005) and Jimoh, (2003).
Considering the fact that one of the main problems
encountered by students in learning Chemistry is that of
inability to organize taught concepts in such a way as to
facilitate ease of recall, it is thus felt that one vital means
of enhancing learning of chemistry is through a method
that would aid students’ memory. This is where
mnemonics come in as a “fun not run”; in teaching and
learning of chemistry.
WHAT IS A MNEMONIC DEVICE?
The word “mnemonic” derives from the Greek goddess of
memory - Mnemosyne, and means "memory enhancing".
Mnemonic ("nee-moh-nick") techniques, also called
mnemonic strategies, mnemonic devices or mnemonics,
are systematic procedures designed to improve our
memory. Hence, mnemonics strategies ought to be
understood as systematic procedures for intensification a
memory. The main idea of mnemonic strategies is
application in developing better ways to encode (take in)
information, so that it will be much easier to retrieve
(remember). Therefore, mnemonic devices can be
attended as learning strategies which can often enhance
the learning and later recall of information (Guthrie, (2002),
and Mastropieri (1998). The main task in developing
mnemonic strategies is to find a way to connect new
information to information students have already locked in
long-term memory. If pupils or students make an enough
strong connection, the memory will last a very long time,
because the mnemonic strategy had carefully linked it to
things that will be very familiar according to these
procedures can be extraordinarily effective. Moreover, the
mnemonic strategies can be incorporated for the elements
that require recall, what is both advantage and
disadvantage of this method.
The vital role of mnemonics as an effective pedagogical
technique had long been established. As an example,
Butcher (2000), explains that the mnemonic techniques
had long been in use by the ancient Greeks and Romans
to improve their memory. Congos (2004), [citing a study by
Miller (1967)] asserted that mnemonics increased recall
and that students who regularly used mnemonic devices
increased test scores by as much as 77%! Mastropieri, and
Scruggs (1998), inform that mnemonics can be modified to
fit a variety of learning content and especially beneficial to
students with learning difficulties. Hayden reported of
medical students’ use of mnemonics in committing
anatomical terminologies to memory. According to Mcalum
and Seay psychologists believe that mnemonic techniques
are so effective in learning because they impose meaning
and structure to material that otherwise would be
unstructured or less meaningful. Among others, studies by
Wang, Thomas, and Ouellette (1992), Iza, and Gil (1995),
Hayden (1995), and Mastropieri, and Scruggs(1998) have
justified the positive effects of the usage of mnemonic
devices in facilitating learning as well as its effects on
students’ abilities to recall learnt facts.
THEORETICAL BASIS OF MNEMONICS AS A
TEACHING METHOD
Constructivism is a learning theory and epistemology that
has influenced much of science education lately. It states
that students construct their knowledge of the world
through their past experiences. Students do not learn
much just by sitting in class listening to the teacher,
memorizing repackaged assignments, and spitting out
answers. They must talk what they are learning, write
about it, relate it to past experiences, and apply it to their
daily lives. They must make what they learn part of
themselves. Ausubel (1968) strongly asserted that “If I had
to reduce all of educational psychology to just one
principle, I would say this: The most important single factor
influencing learning is what the learner already knows.
Ascertain this and teach him accordingly” (p. vi).
Meaningful learning requires the learner to assimilate new
concepts and propositions into existing cognitive
structures. Reviews of psychological foundations of
learning and memory states: the human memory is not a

single “vessel” to be filled, but rather a complex set of
interrelated memory systems… all incoming information is
organized and processed in the working memory by
interaction with knowledge in long-term memory. The
limiting feature here is that working memory can process
only a relatively small number of psychological units (five
to nine) at any one moment … this means that
relationships among two or three concepts are about the
limit of working memory’s processing capacity. For
example, if a person is presented with a list of 10-12 letters
or numbers to memorize in a few seconds, most will recall
only 5 to 9 of these. However, if the letters can be grouped
to form a known word, or word-like unit, or the numbers
can be related to a phone number or something known,
then 10 or more letters or numbers can be recalled. In a
related test, if we give learners 10-12 familiar but unrelated
words to memorize in a few seconds, most will recall only
5-9 words. If the words are unfamiliar, such as technical
terms introduced for the first time, the learner may do well
to recall correctly two or three of these. Conversely, if the
words are familiar and can be related to knowledge the
learner has in her/his cognitive structure, e.g. months of
the year, 12 or more may be easily recalled (Novak
andCañas, (2008). pp 5-6).
Ausubel (1968) theory of learning and Novak and Canas’
(2002) assertion of the value of using familiar words and
concepts to facilitates meaningful learning of bulky facts
and as well as to aid ease of recall, implies therefore that
mnemonics would serve as that scaffold providing the link
between what is already familiar and easy to recall and that
which is to be learnt. This no doubt would enhance the
utilization of the retention of the knowledge for long periods
of time as long as that scaffold can be remembered.
Asides being an effective aid to learning and recalling of
scientific facts, one other significant advantage of
mnemonic devices is that they can be used in a wide array
of situations involving learning of large pieces of
information, “from behaviour to academics to careers to
hobbies” While acknowledging that mnemonics are
considered as cognitive strategies, Spackman(2013)
lament that the use of mnemonics fell into disuse and are
not taught in schools today. They then ascribe ignorance
of the techniques being a possible factor responsible for
lack of its usage.
RESEARCH METHODOLOGY
The research design was pretest-posttest control group
quasi-experimental design. The study was carried out in
Calabar Education Zone of Cross River State, Nigeria. The
sample consisted of 60 Senior Secondary School II
Chemistry students from two schools in one Local
Government Areas in Calabar Education Zone, selected
using the stratified random and purposive sampling
methods. There were 30 students each in the experimental
and control groups. The experimental groups were taught
using Oxidation /Reduction reactions using the following
mnemonics:
Leo says Ger! or Leo the lion, Ger! can be used to
represent Loss of electron is oxidation; Gain of electron
is reduction.
Oil Rig: Oxidation is loss; Reduction is gain (of electrons)
Cations and anions
Cations are positively (+) charged ions while anions are
negatively (−) charged. This can be remembered with the
help of the following mnemonics.
• Cats have paws ⇔ Cations are pawsitive.
• Ca+ion: The letter t in cation looks like a + (plus) sign.
• An anion is a negative ion. (Anegativeion ⇒ Anion).
Cation vs. anion: positive vs. negative
The t in cation looks like a plus sign: "ca+ion".
Cation is positive, anion is negative.
Oxidation vs. reduction: electrochemical cell and
electron gain/loss
AN OIL RIG CAT: At the ANode, Oxidation Involves Loss
of electrons.
Reduction Involves Gaining electrons at the CAThode.
'LOAN'- Left Anode Oxidation Negative [ on the left on side
of the cell reaction (in written form), Oxidation takes place
LEO says GER: "Loss of Electrons, Oxidation; Gain
of Electrons, Reduction".
• Red cat: Reduction at cathode: An ox: Anode
for oxidation.
• The word oxidant and anode, both begins with vowels.
Also, both reduction and cathode begin with
consonants.
• Fat Cat: electrons flow From Anode To Cathode.
The control group was taught using conventional teaching
method without mnemonics. A 60-item five-response
option objective test (Chemistry achievement test, CAT)
developed by the researchers was used as the pretest and
posttest. The CAT items which were drawn to cover all the
sub-topics of Oxidation Reduction reactions on a well-
planned test blue-print were rearranged with its options in
pretest and posttest to have different numbering so as to
give a vague impression that the tests were different. The
reliability of CAT was estimated to be 0.68.Treatment
lasted for a period of four weeks. The first author taught
the experimental groups while the normal teachers taught
the control groups. The data collected with CAT were
analyzed using independent t test.

DISCUSSION
From the analysis of data obtained, it was revealed that
students taught chemistry using mnemonics had a higher
mean of 17.33 in oxidation reduction reactions test when
compared to their counterparts’ mean of 10.20 taught
without mnemonics. The independent t-test value of 8.26
was higher than the critical 2.0 at 0.05 confidence level
with 58 degrees of freedom. Therefore, the null hypothesis
stating that there is no significant difference in the
academic performance of chemistry students when taught
with and without mnemonics was rejected.
Mnemonics in Chemistry classroom significantly affected
students’ academic performance. This research
collaborated studies by Wang, Thomas, and Ouellette
(1992), Iza, and Gil (1995), Hayden (1995), Mastropieri,
and Scruggs (1998) and Akinsola and Adeyeme (2014)
who justified the positive effects of the usage of mnemonic
devices in facilitating learning as well as its effects on
students’ abilities to recall learnt facts.
CONCLUSION AND RECOMMENDATIONS
Findings of this study have shown that Mnemonic is more
effective at improving students’ performance in chemistry.
The results revealed that Mnemonic Instruction had the
higher mean score than the Conventional Teaching
method. The study showed the importance and significant
role played by instructional materials (mnemonics) on
students’ achievement, especially in Chemistry. They
have positive influence in achievement in Chemistry.
The reason is that Mnemonic Instruction enables students
to remember factual information, answer questions and
demonstrate comprehension. It would also provide a visual
or verbal prompt for students who may have difficulty
retaining information. Also, it influences how learners
interpret new information and decide what aspects of that
information are relevant and irrelevant. Based on the
findings of the study, it has been recommended that
teachers should facilitate the use of Mnemonic
instructional strategies in schools to enhance positive
attitude of students towards chemistry and improve their
performance in the subject. They should also include
varieties of Mnemonics into their instructional strategies to
effectively cater for the diverse abilities of students.
Periodic and regular training, seminars and workshops
should be organized for teachers to update their
knowledge on current and creative ways of making
mnemonics at secondary school level. Teacher education
programs would in the same vein incorporate the use of
mnemonic devices as one of the teaching methods to be
taught in chemistry methodology courses. It would also be
important to include the use of mnemonic devices as parts
of the contents of chemistry teacher retraining programs.
Students should be taught on how to produce their own
mnemonics.
