This paper determined the effectiveness of the two media of instruction, English and Filipino, in selected topics in Biology using quasi-experimental research. Two sections of Grade 8 students were the respondents of this study. The researchers found that the difference in scores of the two groups was statistically significant. Students who were subjected to English as a medium of instruction recorded a significantly higher posttest score than those students who were taught using Filipino. Thus, English as a medium of instruction is more effective in teaching selected topics in Biology.

A survey was administered to 600 secondary school students across 10 schools. Results found that all factors had a statistically significant positive correlation with exam scores, with previous preparation having the strongest relationship and attitude/interest having the weakest. The study concluded that multiple variables influence student performance in chemistry.
Causes of mass failure in senior school certificate mathematics examinationsAlexander Decker
1. The study examined the causes of mass failure in Senior Secondary Certificate Examinations in Mathematics as viewed by secondary school teachers and students in Ondo, Nigeria.
2. Key findings from teachers and students included that laziness on the part of students and lack of frequent practice by students were major factors responsible for mass failure. Additional causes included poor mathematical background, parental influence on career choice, and society viewing mathematics as difficult.
3. Teachers and students also identified teacher-related causes such as incompetent handling of difficult topics, poor teaching methods, and lack of practical activities as contributing to mass failure. Government paying poor salaries to teachers was another cited cause.
This study investigated students' attitudes towards the three categories of questions in the WAEC practical chemistry examination: theory of practicals, qualitative analysis, and quantitative analysis. A questionnaire was administered to 50 secondary school chemistry students. ANOVA analysis revealed a significant difference in student attitudes towards the three categories. Post-hoc analysis showed students had the most positive attitude towards theory of practicals, followed by qualitative analysis, with quantitative analysis having the least positive attitude. The study aims to help improve student performance in practical chemistry by identifying areas of weaker attitude to target for encouragement and motivation.

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.
This study examined the effects of using concept mapping on advanced level biology students' lower- and higher-order cognitive skills. Teachers from 8 intact biology classes used concept mapping as an alternative assessment strategy. A total of 156 students participated in the study. Students in the concept mapping groups performed significantly better than the control group on both lower- and higher-order cognitive skills based on a pre-test/post-test. The study found that concept mapping can lead to greater learning gains compared to traditional teaching methods. However, teachers noted that limited time was a challenge to using concept mapping more consistently.

One thing that may affect the students’ perception of mathematics is the attitude of the students towards the subject. This study was conducted to assess the attitude of students towards integral calculus. The subjects of this study were the 94 second year students of the College of Engineering taking up BSAE, BSCE, BSEE and BSME who were enrolled in Integral Calculus. This group of students were a combination of the first timer and repeaters in Integral Calculus. This were the students who were not screened out from the screening examination conducted by the researcher. It employed the descriptive correlational method using the frequency counts, weighted means and analysis of variance.The instrument used in this study was the attitude scale. This instrument was administered to the students before the first screening examination and after the last screening examination.Results revealed that students have favourable attitudes towards integral calculus before and after the screening examination strategy. However, results also revealed that the profile of the students in terms of gender, number of times the student took the subject and the students’ performance on the prerequisite subject has nothing to do or did not influence the attitudes of the students towards the subject.

Effect of Multimodal Instructional Approaches on Students Learning of Chemist...Premier Publishers
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.

This descriptive correlational study determined the language anxiety experienced by Grade 7 ESL learners from four selected junior high schools in the first district of the Division of Northern Samar, Philippines for School Year 2018 2019. The respondents of the study were 286 Grade 7 students who were determined using Slovin's formula. The instrument used in the study was composed of three parts the socio demographic profile of the respondents the factors causing second language anxiety and the language anxiety scale adopted from Horwitz, Horwitz, and Cope's 1986 model of language anxiety. The English performance of the respondents was based on their grades in the English subject. The data were treated statistically using frequency counts, percentages, weighted mean and Pearson r correlation. The findings revealed that in the English performance of the respondents, a majority of them obtained very satisfactory rating in English. Students' second language anxiety especially on language anxiety and fear of negative evaluation were found to be “either anxious or relaxedâ€. On the test of relationship, a significant relationship was found between demographic profile and their English performance. There was also a significant relationship between the demographic profile and the respondents second language anxiety. Age and sex were found significantly related with classroom related factors and teacher related factors. English performance was also found significantly related with communication anxiety and test anxiety. Dr. Rogelio A.

Assessing the Academic Benefit of Study Abroad
Teresa Cisneros-Donahue, Kathleen A. Krentler, Bruce Reinig & Karey Sabol
1. Introduction
Participation in study abroad is growing at a rapid pace. The 2011 Open Doors Report shows that
overseas study by U.S. students was up in 2010 (the most recent available year) by over 10,000
students compared to the previous year (270,604 versus 260,327) (IIE, 2011). U.S. students
studying abroad have more than tripled over the past two decades. The Open Doors report also
emphasized that study abroad is now taking place in a wider range of locations and representing a
wider range of academic disciplines than in the past. Our university has mirrored these trends. We
have experienced substantial and sustained growth in our study abroad program. Study abroad
participation has increased nearly 1000 percent over the past twelve years. Even more importantly,
the perception of study abroad has changed. It is no longer seen as just an optional add-on
experience. The university currently has 37 majors and academic programs that include an
international experience as a graduation requirement. These majors are diverse, from Nursing to
Liberal Studies (pre-teacher education) to International Business, and reflect the academic value
faculty and administrators place on global learning experiences. Study abroad is widely and highly
regarded beyond our university and has been identified as a "high impact educational practice" by
those who study student success rates in the National Survey of Student Engagement (NSSE), a
practice that can lead to increased rates of student retention and student engagement (Kuh, 2008).

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Abstract— This paper determined the effectiveness of the
two media of instruction, English and Filipino, in selected
topics in Biology using quasi-experimental research. Two
sections of Grade 8 students were the respondents of this
study. The researchers found that the difference in scores of
the two groups was statistically significant. Students who
were subjected to English as a medium of instruction
recorded a significantly higher posttest score than those
students who were taught using Filipino. Thus, English as a
medium of instruction is more effective in teaching selected
topics in Biology.
Keywords— Academic performance, Biology, English,
Filipino, medium of instruction.
I. INTRODUCTION
In the field of education, one of the important factors that
should be given attention is the language or medium of
instruction because it is one way to ensure the efficient and
effective transmission of information during the learning
process. The authors in [1] state that“ language of
instruction is a vehicle through which education is
delivered. Through language, the process of teaching-
learning process is possible.”
The study conducted by the International Studies of
Educational Achievements (ISEA) on science achievements
among 10-year old students throughout the world cited by
the author [2] showed that the Hungarians, Swedes,
Japanese, Koreans, and Norwegians who were taught and
learn Mathematics and Science in their national language,
got the highest scores in the International Education
Assessment Test. Unfortunately, the Philippines obtained
the lowest mean score in Mathematics and Science
achievements. The result of the study shows that Filipino
children, who were taught Mathematics and Science in a
foreign language, perform far below than the students of
other countries.
The researchers in[3] “documented that teachers believe
English-medium instruction to be a setback to students’
academic success and students stated that they could not
understand the subject matter when the lectures are in
English.” The authors in [4] found that “English-medium
instruction had considerable negative effects on geography,
science, and world history.”In the same manner, reference
[5]“found similar differences in economics, geography,
history, physics, chemistry, biology, and mathematics.” In
addition, the result of the study by [6] “suggests that
instruction in English significantly and negatively affects
the academic success of the students.”
According to[7], “the use of mother tongue, which refers to
the Filipino language in the Philippines, by the teachers
plays a crucial role in the learning of subjects which
contributed immensely to the understanding of the students
in their lesson.” In addition, [8] said that “mother tongue
education should be given importance in educational
policies and children should be taught in a language they
understand and the same language should be used in the
classroomin the early six years of education.”
In contrast, the disadvantage of using mother tongue in
teaching science particularly Biology are it contains many
technical terms in describing its concepts, principles and
theories, and is, therefore, more susceptible to reading
difficulties than other natural sciences [9]. The author in
[10] state that “learners in private schools perform much
better in Biology as compared with learners in public
schools because learners in private schools had a better
English proficiency.”
It was observed that the preferred language use as a medium
of instruction is also a factor since students often have a
difficult time to understand the language used by the teacher
as well as the language used in the learning material and
examination [11 and 12].
Because of these reasons,the researchers ventured on quasi-
experimental research to compare and find out the

effectiveness of English and Filipino as media of instruction
in teaching Grade 8 students of selected topics in Biology.
The result may serve as a benchmark for the researchers to
develop a plan of action that will help Grade 8 students with
their existing problem in Biology.It is in this regard that this
study finds meaning and significance.
II. MATERIALS AND METHODS
The study utilized Campbell and Stanley‘s quasi-
experimental design of the non-equivalent pretest-posttest
control group design [13 and 14]. According to the author
[15], “quasi-experimental design was used to evaluate the
effectiveness of an intervention when the intervention has
been implemented.”
The two sections of Grade 8 students were selected using
purposive sampling. “Purposive sampling is a non-
probability sampling method and it occurs when elements
selected for the sample are chosen by the judgment of the
researcher” [16].
The researchers conducted the study in March 2018 at Juan
R. Liwag Memorial High School, located at Barangay
Bayanihan, Gapan City, Nueva Ecija, Philippines. Informed
consent from parents and assent fromthe respondents were
secured by the researchers before doing the experimental
process for ethical considerations. The research instruments
used were the pretest and posttest questionnaires. The
statistical tools utilized in this study were frequency,
percentage, weighted mean and independent sample t-test.
III. RESULTS AND DISCUSSION
3.1 Academic Performance of the Respondents
Before the experimentation, student respondents were given
a pretest in Biology about Cell Division and Genetics.

Table (1) showed the academic performance of the two
groups of respondentsin their pretest. In the group who were
taught in English, 28 (44.4%) got scores ranging from 9 to
16 with a verbal description of Developing or Fairly
Satisfactory. There were 20 (31.8%) who got scores ranging
from 17 to 24 with a verbal description of Approaching
Proficiency or Satisfactory and 13 (20.6%) got scores
ranging from 25 to 32 with a verbal description Proficient
or Very Satisfactory. Only 1 (1.6%) got a score ranging
from 33 to 40 with a verbal description of Advanced or
Outstanding and was under Beginning or Did not Meet
Expectations whose score ranged from 0 to 8.
Meanwhile, in the group who were exposed to Filipino as a
medium of instruction, 34 (51.5%) got scores ranging from
9 to 16 with a verbal description of Developing or Fairly
Satisfactory. There were 21 (31.8%) who got scores ranging
from 17 to 24 with a verbal description of Approaching
Proficiency or Satisfactory and 10 (15.2%) got scores
ranging from 0 to 8 with a verbal description Beginning or
Did not Meet Expectations. Only 1 (1.5%) student was
under Proficient or Very Satisfactory whose score ranged
from 25 to 32 and nobody reached the Advances or
Outstanding level.
The result on both groups is related to the findings in [17],
that Filipino students’ academic performance in Biology
which is under the subject of Science and Technology is
weak.

Table (2) showed the academic performance of the two
groups in their posttest. In the English group, there were 22
(34.9%) respondents who earned scores ranging from 33 to
40 with a verbal description of Advanced or Outstanding.
Eighteen (28.6%) got scores ranging from 9 to 16 with a
verbal description of Developing or Fairly Satisfactory, 13
(20.6%) got scores ranging from 17 to 24 with a verbal
description of Approaching Proficiency or Satisfactory and
10 (15.9%) got scores ranging from 25 to 32 with a verbal
description of Proficient or Very Satisfactory. Nobody was
under Beginning or Did not Meet Expectation level.
On the other hand, in the Filipino group, 25 (37.9%) got
scores ranging from 9 to 16 with a verbal description of
Developing or Fairly Satisfactory. There were 18 (27.3%)
who got scores ranging from 17 to 24 with a verbal
description of Approaching Proficiency or Satisfactory and
17 (25.7%) got scores ranging from 25 to 32 with a verbal
description Proficient or Very Satisfactory. Four students
were under Beginning or Did not Meet Expectations whore
scores ranged from 0 to 8 and only two students were under
Advanced or Outstanding level whose scores ranged from
33 to 40. This shows that the respondents in the English
group after the use of English language as a medium of
instruction in teaching Biology to learn betterthan of the
respondents in the group where the Filipino language was
used as a medium of instruction in teaching Biology.
The finding of the study contradicts the findings of the
following authors [18], [19] and[20], [21] and [22].
According to them, the use of the English language would
seriously affect and become a limiting factor for student
learning, and learners encounter enormous problemlearning
Biology. However, according to the following authors [23]
and [24], “science and mathematics are dynamic areas of
knowledge in which all sorts of new discoveries and a large
portion of information related to them are found in English
and should be taught in English.”

Table (3) showed that the English group had higher pretest
and posttest score. The statistical analysis revealed that the
pretest and posttest scores between the two groups have
significant differences. This meant that the performance of
the respondents in the English group after the use of English
language as a medium of instruction is greater than the
performance of the respondents in the experimental group
where the Filipino language was used as a medium of
instruction.
The result of the study implies that the use of the English
language as a medium of instruction is more effective than
the Filipino language in teaching science. The author in [25]
stated that it is based on the fact that the language of
instruction plays a significant role in students' academic
performance. The reason why the control group had a
higher posttest score was that the mediumof instruction use
was English and the language used in Biology which is
under the subject of science was English. Since scientific
and technological development is mostly recorded in
English language, according to authors [26] and [27], “one
advantage of using English as a mediumof instruction is the
higher quality of support materials compared to those in
local languages.”“Textbooks, articles, support websites,
practice questions are better in both quality and quantity in
English than in any other language. “Therefore, it is a
disadvantage for all who do not use the English language
because they may not have access to the world’s known
scientific and technological discoveries that are
predominantly written in English” [28].
According to [29], “teachers and students prefer the use of
English as the medium of instruction. The teachers find
English as a more comfortable language for explaining
ideas and concept and a valuable tool to source information
technology.”The findings of the author in [30] showed that
the students had better learning performances when English
was used as a medium of instruction than Filipino in
teaching Social Sciences. Because of this, it is more
advantageous to use the English language in teaching
Biology than any language.
IV. CONCLUSIONS AND
RECOMMENDATIONS
Innovative and successful teachers should have the
knowledge and the sense of purpose that allows themto rise

above casual or conventional approaches and to do things
others cannot [31] as cited by [32].
The researchers, being innovative teachers ventured on
different approaches in teaching selected Biology and found
out that the academic performance of the respondents under
the group who were taught in English had statistically
higher mean posttest score from those students under the
group who were taught in Filipino. Language then appeared
to have an effect on the students' academic performance.
Hence, English as a medium of instruction was more
effective in teaching selected topics in Biology. However,
since the study is only limited to five topics in Biology, this
study must be replicated on a larger scale over a longer span
of time in order to attain more defined results. The
researchers suggested taking the whole grading period
which means more topics will be added. The same study
may be undertaken for the Grade 8 students of private
schools, which this study fails to include. Likewise, teachers
and professors may consider a game-based teaching-
learning process [33] in Biology which was proven to help
the students be engaged in lessons regardless of the
language of instruction. Lastly, the use of English and
Filipino language as media in constructing modules should
be conducted in order to determine if the language will have
an effect in the performance of the students if it used as
supplementary material.
