The rising interest in environmental literacy and education for sustainability has created  expectations that timely, accurate content should be taught to the primary, secondary as well as  teacher education curriculum. The learning context should provide opportunities for students to  develop critical thinking skill, problem solving and values. Project-based learning approaches that  emphasize student learning may be a key to the successful development of good citizenship. The  purpose of this study is to investigate the effect of a project-based learning on students'  environmental knowledge, attitudes and behaviour. As part of the course requirements students were  asked to develop a web-quest on climate change and to identify-suitable topics in the curriculum  for the integration of climate change.  The topic on climate change was chosen since global climate  change is a challenging topic to teach and learn and the teaching is flawed through omission,  simplifi.....

Xylitol is a sugar alcohol, its molecular structure is hybrids between the molecule of sugar and the molecule of alcohol. Xylitol can be used as a sugar substitute in human uptake especially diabetes because it does a minimal effect on the blood sugar level. The properties of xylitol can be modified to be suit to replace sugar. Therefore, the main purpose for this research studies was to find what modification can be made on xylitol properties so that it is suitable to substitute sugar for sugar uptake in human and to prove that not all the commercial xylitol can be used to substitute sugar. In this research the pH of the xylitol were changed to the suitable pH value. Then they were observed using UV-vis and FTIR to determine the changes on the composition of the modified xylitol. Keywords Xylitol, pH, Sugar, UV-Vis., FTIR..

This study aimed to develop an android-based mobile learning application, Skeletopedia based on the cognitive constructivism and cognitive theory of multimedia learning and evaluated its usability as an educational tool for Form Five Biology students. The Skeletopedia was developed according to ADDIE model. It was designed to aid the Form 5 students in understanding and remembering the Latin terminology of human skeletal system as well as allowing them to visualise the human skeleton through three-dimensional augmented reality skeletal models. Two biology teachers were appointed to assess the face and content validity of the questionnaire and Skeletopedia, while 97 Form Five Biology students from Mara Junior Science College (MJSC) FELDA Trolak were selected as respondents for the field study. The usability questionnaire developed in this study had obtained high validity (κ = 1.00, CVI = 1.00) and reliability (Cronbach’s Alpha Coefficient = 0.970). The ‘Skeletopedia’ application .....

The complexity of meiosis, combined with a lack of knowledge about chromosomes and misconceptions, contributes to students' difficulty understanding this process. Therefore, this study aimed to develop a Cell-Wolf Game as a teaching tool for form four biology students learning about meiosis and to assess its usability based on teacher trainees' perceptions. This study uses a developmental research design by employing ADDIE model as the instructional design model. Two instruments were used in this study: expert validation form and the usability perception of the questionnaire. Two biology lecturers have been appointed to assess the validity of teaching aid material content and questionnaires. A total of 103 trainee teachers from the Bachelors of Education (Biology) programme were selected as respondents for the field study. The study showed the content validity index for both the teaching aid material, and the questionnaire is 1.0, meanwhile, the reliability index for questionnaire was .....

Kajian yang dijalankan ini bertujuan meninjau penggunaan media elektronik dalam pengajaran dan pembelajaran dalam kalangan guru-guru di daerah Kinta. Kajian ini juga bertujuan mengenal pasti masalah yang berkaitan dengan penggunaan media elektronik dan pandangan guru mengenai keberkesanan penggunaan media elektronik dalam pengajaran dan pembelajaran. Responden kajian terdiri daripada 153 orang guru daripada sebelas buah sekolah di daerah Kinta yang dipilih secara rawak. Pengumpulan data telah dibuat dengan menggunakan soal selidik. Data yang dikumpul dianalisis dengan menggunakan kaedah statistik seperti kekerapan, peratusan ujian t, ANOVA sehala dan korelasi pcarson . Hasil kajian mendapati bahawa tahap penggunaan media elektronik dalam pengajaran dan pembelajani masih lagi berada pada tahap yang rendah. Hal ini dipengaruhi oleh beberapa masalah seperti kekurangan bahan atau perisian yang sesuai, beban tugas lain di sekolah dan kekangan masa. Sungguhpun begitu hasil analisi.....

Online learning is a difficult type of educational process due to its limitations, particularly in college mathematics courses. The essential aim of this article is to elucidate the students' difficulty level in learning mathematics amid online learning and predict its statistically significant influencing factors. The data used in this study is secondary from a paper in the mathematics education literature on the form of cross-sectional. The data were summarized employing some descriptive measures and regression modeling as an inference. The result of the study showed that, on average, students are facing "difficulty" in learning their mathematics lessons during distance learning due to some problems. The quantile regression revealed that younger and female students are experiencing higher levels of difficulty. Plus, students who spent more money on the internet are facing higher difficulty in learning. In addition, a not conducive learning environment and social distractions are pred.....

Students have different kinds of acquisition styles depending on their convenience in the learning environment. This study aims to look into the different kinds of learning styles (visual, auditory, and tactile) among students in learning statistics during the new normal at Visayas State University, Leyte, Philippines. In addition, the article tends to determine the various correlating factors that significantly influence their learning styles. Secondary data were utilized from an existing current paper in the literature and analyzed using standard descriptive statistics and ordinal regression. Results of the analysis showed that students' learning styles as visual, auditory, and tactile are rated "sometimes." This indicates that the learning ability of students is adversely affected by the pandemic. On average, students preferred a visual learning style during the new normal in their acquisition of distance statistics education. This means that students prefer to read visual represent.....

Globally, the COVID-19 presents a serious concern to the wellbeing of people. COVID-19 was first detected in Wuhan, China. The disease became a source of concern for Nigerians after the country registered its first case in February 2020. Currently, the country has recorded 255,103 confirmed cases, 249,246 recovered cases, and 3,142 deaths as of March 21, 2022. We proposed a SEQIHRV model to investigate the spread of coronavirus disease in Nigeria. This model defines the infection dynamics' transmission routes as well as effect of contaminated surfaces on the human population. Unfortunately, the virus's propagation and mortality from COVID-19 is increasing daily. Therefore, it is required to manage and control the flow of the infection. The impact of control measures as time-dependent interventions was investigated in this study utilizing optimization technique to determine their effects on the spread of Corona virus. The basic reproduction was calculated and used to calcite the sensit.....

The key purpose of this research is to explore the experiences of the parent-teachers on teaching Mathematics of Grade 1 and 2 learners who undergone modular distance learning in Magallanes, Sorsogon. The descriptive qualitative research design was used to describe the experiences of parent-teachers in teaching Math with the use of modules; identify the strategies used to teach and manage learning; and determine the support provided by the school in teaching Math. Validated questionnaire and semi-structured interview were utilized to gather data from five parent-teachers who were in early adulthood, college graduate, employed, and spending at least thirty minutes in teaching their child. With the use of deductive approach of thematic analysis, the experiences of the parent teachers were categorized into learning environment and child’s motivation and attitude towards learning, instructional time and resources, content of the learning modules and being an effective teacher. As to the .....
