This study investigates the Effects of Using Gagne’s Learning Hierarchy on Chemistry Students’ Academic Achievement and Anxiety level in Balancing Chemical Equations in Secondary Schools. The study sample used 100 SSII students randomly selected from two Senior Secondary Schools in Katsina Metropolis. The two schools were randomly placed as experimental and control groups each with 50 students. A quasi-experimental pretest-posttest research design was used for the study. The study subjects in the experimental group were taught using Gagne’s learning hierarchy, while the control group was taught using lecture method for the period of six weeks. Two instruments; Balancing Chemical Equation Achievement Test (BCEAT), and Students’ Anxiety Scale Questionnaire (SASQ) with reliability coefficient of 0.79 and 0.78 respectively, were used to collect data for the study. Performances of the two groups were compared using their posttest mean scores. The major findings from the study are: Students taught using Gagne’s learning hierarchy recorded high academic achievement than those taught using to lecture method. The anxiety level of students taught using Gagne’s learning hierarchy tended to be low when compared with students taught using lecture method. Based on the findings, the following recommendations were made: Chemistry teachers should as much as possible arranges concepts taught in Chemistry hierarchically so that students can learn the simple concepts which will help their understanding of abstract or complex concepts.

HOTS Analysis to Develop E-Supplement Book Based on Plant Physiology ResearchMd. Mehadi Rahman
Biology learning, especially the topic of plant physiology, requires Higher Order Thinking Skills (HOTS). This ability needs to be improved with HOTS based teaching materials. The teaching materials, however, have not been developed, especially those in plant physiology topic. Students’ HOTS in biology learning still requires an improvement as HOTS is important for the 21st century. One alternative that can be developed is teaching materials in the form of an E-Supplement Book Based on Plant Physiology Research (ESPPRe). The purpose of this study was to measure students’ HOTS related to the concept of plant physiology as the basis for developing ESPPRe. The method used was descriptive using a survey technique. The instrument used in this study amounted to 10 items distributed using Google form. The results indicated that the scores were categorized as low for all students (40.81) with male students (41.39) and
female students (40.74). This suggested that the HOTS score still needs to be improved and it is necessary to develop ESPPRe in further research. The content on the ESPPRe media that must be developed is related to activities to analyze and criticize problems that have been presented in ESPPRe. Next, students are expected to be able to create solutions and ideas related to these problems. The development of various learning media will make students happier in learning. This is because HOTS-based learning implementation will be varied. This study concludes that the HOTS score is still in the low category and the ESPPRe can be developed in subsequent studies. Suggestion from this research is to be able to implement the book to improve students' abilities to solve problems.
This document summarizes a study that explored factors influencing students' decisions to enroll in physics courses at the University of Education, Winneba in Ghana. The study found that students did not perceive their parents as influencing their subject choice and did not feel societal influence swayed their decision either. It used a questionnaire to collect data from 216 physics and biology students. Background factors like parental education levels and socioeconomic status have been shown in other studies to influence subject selection, but patterns may differ in Ghana's context with generally low socioeconomic levels.

This study examined the impact of "mathemagenic activities" on gender differences in understanding chemistry concepts. 360 Nigerian high school students were given pre- and post-tests after exposure to experimental or control conditions. Results showed students in experimental groups that used instructional objectives, adjunct questions, and combined modes performed better than control groups, with no significant differences between male and female students. The study suggests these approaches can be adopted in chemistry classes without emphasizing gender. Previous research on gender differences in science achievement has been inconclusive, though some studies found males perform better in chemistry problem-solving while females outperform in language arts. This study investigated whether gender impacts chemistry performance when using mathemagenic activities.

The study determined the effect of Multiple Intelligence Based Instructional Technique (MIBIT) on
students’ achievement and interest in the learning of difficult biology concepts. Two research questions were
asked and two research hypotheses were formulated and tested at 0.05 level of significance. The research
design was a quasi – experimental study. The sample was made up of seventy four (74) senior secondary one
(SS1) students from two randomly selected co-educational secondary schools from Aguata Education Zone of
Anambra state. The Biology Interest Scale (BIS) was the instrument used for data collection. Cronbach Alpha
was used to determine the reliability of BIS which yielded the coefficient of internal consistent of 0.85 . Mean
and standard deviation were used to answer the research questions while Analysis of Covariance (ANCOVA)
was used to test the null hypotheses at p<0.05. The result of the findings indicated that MIBIT promotes
academic interest in difficult biology concepts. Gender was discovered to have no significant influence on
students ’academic interest. No interaction effect existed between MIBIT and gender on students’ overall
interest. Conclusion from the findings led to various recommendations, some of which are that biology teachers
should adopt the MIBIT in the teaching of difficult biology concepts in order to carter for the diverse learning
styles of students in their classroom and promote students’ interest. Curriculum designers should integrate
MIBIT in the curriculum and teachers should be sponsored to workshops and seminars on how to improve their
teaching skills using MIBIT
Qualitative Chemistry Education: The Role of the TeacherIOSR Journals
This document discusses the role of chemistry teachers in improving the quality of education in Nigeria. It identifies several factors that have contributed to the decline in quality, such as unqualified teachers, examination malpractice, and lack of practical skills. The document outlines strategies chemistry teachers can use, including changing from a lecture method to cooperative learning, concept mapping, and using information communication technology. It also stresses the importance of improvisation given limited resources. The document concludes by recommending that teachers adopt innovative teaching strategies and the government provide more funding and support for teacher training.
This document discusses a study that examined the effects of an Experiential Cooperative Concept Mapping (ECCM) instructional approach on secondary school students' motivation to learn physics in Nyeri County, Kenya. The study used a quasi-experimental research design involving 513 students from 12 schools. Students in the experimental groups were taught using ECCM, while the control groups used Regular Teaching Methods. Results from pre- and post-tests using a Student Motivation Questionnaire found that students taught with ECCM had significantly higher motivation to learn physics compared to those taught with regular methods. The researchers recommend using ECCM to address low student motivation in physics.

The study was focused on Physics teachers’ perception on the use of ethnoscience learning experiences for the teaching of secondary school Physics and its implication for curriculum implementation. Six research questions and six hypotheses were posited for the study. The cross sectional survey research design was employed for the study. 243 secondary school Physics teachers in three Urban Local Government Areas Port Harcourt, Obio Akpor and Eleme and four rural Local Government Areas Ikwerre, Khana, Ahoada East and Ahoada West in Rivers State, Nigeria were selected using the non proportional stratified random sampling technique. Data collecting instrument was titled “Ethnoscience Learning Experience for Physics Teaching Questionnaire” with a coefficient reliability index of 0.86 was used to elicit response from the respondents. Data was analyzed using frequency count, mean, and inferential statics of t test at 0.05 level of significance. The findings of the study revealed that the following themes Interaction of Matter, Space and Time, Conservative Principle, Waves Motion without material transfer and Fields at rest and in motion can be taught using ethnoscience learning experiences while themes such as Energy quantization and duality of matter and Physics in technology cannot be taught using ethnoscience learning experiences. Based on the findings of the study, it was recommended that stakeholders and planners of the secondary school Physics curriculum should consider the integration of ethnoscience learning experiences in the Physics curriculum in order to clarify those abstract concepts in learning of Physics.

Concern has been expressed about the motivational impact of neuro-anatomy award/prize in determining the overall student performance in the final professional anatomy examinations by comparing it with the result outcome of a high stake examination like neuro-anatomy incourse examination using the concept of convergent validity. A total of 57 third year medical students with the records of their grades/scores (Mean ± SD) in the various assessments criteria, were analyzed. In this study, the neuro-incourse examination was consistently a high predictor (r = 0.80; P<0.01)><0.01>< 0.01 respectively). However, the neuro-incourse examination tests students’ performance in a relatively difficult module and was found to be consistently correlated and highest when compared with the overall professional examination as a result of student motivation.

This study examined Nigerian science teachers' perceptions of effective science teaching and their actual classroom practices. It found that while teachers believed effective teaching involves more student-centered activities like hands-on work, their actual teaching spent more time on teacher-centered methods like explanation and note-giving. The study also found that teachers felt constrained by large class sizes, lack of materials and labs, and an overloaded curriculum focused on exams over understanding. Recommendations were made to improve teaching practices to better align with perceptions of effective science instruction.

HOTS Analysis to Develop E-Supplement Book Based on Plant Physiology ResearchMd. Mehadi Rahman
Biology learning, especially the topic of plant physiology, requires Higher Order Thinking Skills (HOTS). This ability needs to be improved with HOTS based teaching materials. The teaching materials, however, have not been developed, especially those in plant physiology topic. Students’ HOTS in biology learning still requires an improvement as HOTS is important for the 21st century. One alternative that can be developed is teaching materials in the form of an E-Supplement Book Based on Plant Physiology Research (ESPPRe). The purpose of this study was to measure students’ HOTS related to the concept of plant physiology as the basis for developing ESPPRe. The method used was descriptive using a survey technique. The instrument used in this study amounted to 10 items distributed using Google form. The results indicated that the scores were categorized as low for all students (40.81) with male students (41.39) and
female students (40.74). This suggested that the HOTS score still needs to be improved and it is necessary to develop ESPPRe in further research. The content on the ESPPRe media that must be developed is related to activities to analyze and criticize problems that have been presented in ESPPRe. Next, students are expected to be able to create solutions and ideas related to these problems. The development of various learning media will make students happier in learning. This is because HOTS-based learning implementation will be varied. This study concludes that the HOTS score is still in the low category and the ESPPRe can be developed in subsequent studies. Suggestion from this research is to be able to implement the book to improve students' abilities to solve problems.

The study determined the effect of Multiple Intelligence Based Instructional Technique (MIBIT) on
students’ achievement and interest in the learning of difficult biology concepts. Two research questions were
asked and two research hypotheses were formulated and tested at 0.05 level of significance. The research
design was a quasi – experimental study. The sample was made up of seventy four (74) senior secondary one
(SS1) students from two randomly selected co-educational secondary schools from Aguata Education Zone of
Anambra state. The Biology Interest Scale (BIS) was the instrument used for data collection. Cronbach Alpha
was used to determine the reliability of BIS which yielded the coefficient of internal consistent of 0.85 . Mean
and standard deviation were used to answer the research questions while Analysis of Covariance (ANCOVA)
was used to test the null hypotheses at p<0.05. The result of the findings indicated that MIBIT promotes
academic interest in difficult biology concepts. Gender was discovered to have no significant influence on
students ’academic interest. No interaction effect existed between MIBIT and gender on students’ overall
interest. Conclusion from the findings led to various recommendations, some of which are that biology teachers
should adopt the MIBIT in the teaching of difficult biology concepts in order to carter for the diverse learning
styles of students in their classroom and promote students’ interest. Curriculum designers should integrate

Effect of Qualification and Experience of Biology Teachers on the
Status of Ecology Teaching in Kwara State
Isaac O. Abimbola Ph.D and Florence O. Abidoye
Department of Science Education, University of Ilorin, Ilorin, Kwara State.
Abstract
This study examined the effect of qualification and experience of Biology teachers on the status of ecology
teaching in Kwara State. This study sample included one hundred and forty two (142) Secondary Schools
selected by random sampling technique. The researcher designed teachers’ questionnaire which were
administered to four hundred and fifty (450) teachers selected from eight (8) Local Government Areas of Kwara
State. Researcher-designed validated questionnaire was used to elicit information from the respondents on the
status of ecology teaching. Three research questions and two hypotheses were formulated. Frequency counts and
chi- square statistics were used to analysis the data collected. Finding of this study revealed that 68% of Biology
teachers agreed with the contents while 32% disagreed. However both qualified and unqualified teachers had
viewed ecology teaching the same way that is ecology teaching was not properly done due to the fact that some
Biology teachers skip certain areas of the syllabus that they find difficult to teach. Similarly, experienced and
less experienced teachers had the same views about ecology teaching in Kwara State. Based on the findings, the
following recommendations were made: fieldwork and practicals on Ecology should be carried out satisfactory
in the schools, teachers should be sponsored to seminars and workshops specifically on Ecology teaching.
Introduction
Biology deals with the study of all the varied aspects of living organisms. It is one of the science
subjects, offered by candidates sitting for the senior school certificate (SSC) ordinary level examinations.
Biology is the most popular subject among the pure science subjects (Idodo, 1996). Biology at the senior
secondary school level can be grouped under such headings as: Cell and Unicellular Organisms, simple
multicellular animals, insects, the arthropods, higher animals, reptiles and birds, mammals, flowerless plants,
flowering plants, physical processes found in living organisms, respiration, food substances, nutrition of green
plants, transport systems, excretion, ecology, etc. Ecology is the study of interactions of organisms with their
physical environment and with each other. No plant or animal is independent of its environment.
If organisms must survive, then the environment must provide suitable conditions for their existence
because they are likely to be affected by conditions around them (Stone, 1990). Ecological studies deal with any
of the three levels of the organization of the organism, the individual, the population and communities. It deals
also with the way in which the organisms at each of these levels of organization function in harmony with the
non living physical environment. Ecology has many useful applications aimed at maintaining a healthier and
more productive biosphere for the life of humans and other living organisms. It provides for the judicious use of
natural resources often referred to as conservation. (Ndu, 1990). The sub topics under ecology at the senior
secondary school level are basic ecological concepts, Aquatic habitants, Fresh water, Swamps, Marsh, Estuary,
Grass land, Major biomes of the world, ecology of Population study and Problem of survival etc.
The following are the objectives for teaching senior secondary school Biology:
1.
To provide basic literacy in Biology for functional living in the society.
2.
To acquire essential scientific skills and attitudes as a preparation for the technological application
of Biology.
3.
To acquire basic concepts and principles of Biology as a preparation for further studies.
4.
To stimulate and enhance creativity (National Biology Curriculum, 1993 page 20-22.
The focus of the secondary schools is to produce students that will proceed to tertiary institutions for
further education. Some researchers reports shows that teachers found some concepts in ecology difficult
(Ndukwe, 1988). Okeke and Ochuba (1986) worked on the level of understanding of ecological concepts. The
study revealed low understanding of the three selected concepts by secondary school certificate students on some
selected ecology concepts such as population, habitant and ecosystem. Apart from the three selected concepts,
the findings call for further investigations of the other ecology concepts so as to improve the understanding of
these concepts among secondary school students and to know the best method to be employed in teaching them.
Jegede and Lagoke (1986) worked on the status of ecological field works in Nigerian secondary schools and
found out the teachers did not have a positive attitude towards the teaching of ecological work. Adeniyi (1985)
worked on misconceptions held by junior secondary school students in selected ecological concepts and found
out that the absence of Yoruba equivalent of the ecological concepts was a factor for such misconception held by
students. Ugwuandu (1984) worked on problems of teaching ecology and genetics at the secondary school level

The results in table 1 show a decline in students’ performance in years sampled, 2008-2010. The
percentage of students that had credits was very low compared to the total entry. In 2008-33.9%, in 2009-28.6%
and in 2010-33.9% throughout the examination results, the performance of biology students was always below
60% of the total number students who offered biology in the external examination. In the years 2008, 2009 and
2010 . The percentage failures were 38.4%, 35.2% and 38.4%. It could therefore be seen from the table that
percentage failure of students’ performance increased yearly. The result above showed are the same for all the
senior secondary schools in Nigeria. Many reasons have been advanced for the poor performance such as
i.
Negative attitude of both teachers and students (Akintoye & Shofuyi, 2002)
ii. Lack of adequate laboratory equipment (Jimoh, 1992)
iii. Some teaching methods adopted by Biology teachers (Harbor – Peters & Ogomeka, 1991)
iv. Teachers’ difficulty in understanding and teaching of certain Biology concepts (Abimola, 1998)
v. Inadequate coverage of the Biology syllabus (WAEC, 1985).
Ecology is one of the difficult concepts to both teachers and students of Biology (Abimbola 1998:
NERDC, 1993: Oyeyemi 1991 and Ugwuandu, 1984, Soyinka 1983 and WAEC, 1998 – 2000). Researchers
reported that most teachers in Nigeria secondary schools grossly neglect the teaching of ecology like that of
genetics. The Chief Examiner’s report on Ecology revealed low achievement in ecology by students (WAEC
2004). In all the studies examined, ecology was difficult due to the following reasons:
i. Neglect of ecology by most secondary school teachers
ii. Academic ability and area of specialization of teachers
None of the studies above examined knowledge of teachers and experience of biology teachers. Hence, the
need for this study.

There were two hundred and nine (209) Qualified and 241 unqualified respondents. And also there were 268
experienced and 182 less-experienced Biology teachers.
Research Question One
What is the status of Ecology teaching in senior secondary schools in Kwara State as viewed by
Biology teachers?

The average results of the analysis related to the research questions as are shown in table 4. From Table
4, the Chi-square calculated (X2 Cal) was 0.41, while the table value was 3.84 at 0.05 alpha levels, with degree
of freedom of 1 this shows that the views of Biology teachers on the teaching of Ecology did not vary
significantly with qualifications. With this, the null hypothesis (H02) was not rejected.
Similarly, the calculated X2 for experience of teachers was 0.56 while the table value was 3.84.
Therefore H03 was not rejected. This table 4 shows that both the Qualified and Unqualified have similar opinion

to that of the experienced and less experienced Biology teachers about the teaching of Ecology in Kwara State.
Summary of Major Findings
In this study, the major findings are
1)
Ecology teaching was accorded low status in Kwara State with 68% agreement of Biology teachers that
said that there should be improvement in the Biology curriculum of some Ecology concept that are
lacking.
2)
Both qualified and unqualified biology teachers agreed that Ecology teaching was not due to the fact
that some Biology teachers skip certain areas of the syllabus that they find difficult to teach.
3)
Experienced and less experienced teachers agreed that ecology teaching was not properly done.
Discussion of Results of Status Ecology Teaching
In this study, it was found out that ecology teaching had low status in Kwara State, and has effect on
students’ performance. The finding agreed with Adeshina (2007), Ogundele (1995) and Ojaleye (1997).
The results of the study indicated that many Biology teachers had the views that the status of teaching is
very important in the teaching of Ecology. With respect to the qualification, the qualified agreed with
unqualified Biology teachers that some teachers skip certain areas of the syllabus that they find difficult to teach.
The findings agreed with Mgbako-Ezemia (1992), Ogundele (1995) and Ojaleye (1997).
The experienced and less experienced teachers agreed that ecology teaching was not properly done as a
result of not exposing the Science teachers to seminar and workshop. The finding agrees with those of Ndukwe
(1988), Abdullahi (1983), Fafunwa (1974), Balogun 1982 and Saha (1983).
Recommendations
Field work and practicals on Ecology should be carried out satisfactorily in the schools.
Teachers should be sponsored to seminars and workshops specifically on Ecology teaching.
Suggestions for further Studies
The following suggestions are made for further studies: this research work can be replicated in other
part of Kwara State of the country since this study is limited to eight Local Government Areas of Kwara State.
Also the Science education students could start from where this work end by creating many instructional aids
that could be used to teach Ecology and other concept that are perceived difficult by many Biology teachers.
Moreover, other researchers can equally examine other variables such as area of specialization, type of
schools and others that have not been addressed in this study.

Ecology in the curriculum is
arranged in a conceptual manner
Learning about ecosystems should
involve field work
Specific samples illustrative of
adaptive features of organisms
should be brought into the class
room
Emphasis should be placed on
identifying adaptive features of
organisms.
Food scarcity as an ecological
problem should be emphasized.
Some important ecology concepts
are lacking in the Biology
curriculum.
In studying an ecosystem, sizes of
ecosystem and population of many
organisms should be determined.
The biology curriculum is loaded

with too many ecology concepts.
The arrangement of ecological
concepts in such a way that they
run throughout the three year
course is convenient for teaching.
Non availability of Biology
textbooks affects the teaching of
ecology in senior secondary
schools.
Actual measurements of ecological
factors should be taken.
The students should be guided to
study an ecosystem.
A field trip should be made to a
biotic community.
Students should collect organisms
from the ecosystems and classify
them as producers, consumers or
decomposers.
Students should be able to measure
or estimate sizes of some
ecosystems.
Students should be able to give
names of organisms typical of each
community
Students should be able to describe
each of the factors and point out
their relative importance.
The factors which affect water
retentivity of soil-types and
determine the amount of water
each soil type can hold should be
known by the students.
Students should be guided to study
land ecosystem.
Interpretation of graphs showing
ecological factors of an area should
be determined.
Students should be able to name
soil types and discuss their effects
on vegetation.
Students should be able to
demonstrate how climatic factors
are measured.
Students should be able to state the
sources of energy in an ecosystem.
Students should be able to
recognize that food relationship
exists among living things.
Students should be able to use the
knowledge of energy losses in the
ecosystem to explain the pyramidal
shape of feeding relationships.
Students should be able to identify
some associations which are
beneficial, harmful and neutral to
each of the organisms of the
association.
