COGNITIVE DISTORTIONS AS A PREDICTOR OF STUDENTS’ ACHIEVEMENT IN BIOLOGY IN COLLEGES OF EDUCATION IN ANAMBRA STATE
No full textThe study investigated cognitive distortions as a predictor of biology students’ academic achievement in College of Education in Anambra State. Two research questions guided the study and two null hypotheses were tested at 0.05 level of significance. The predictive correlation design was adopted for the study. The population of the study comprised 283 year three (300 level) Biology students in the two public Colleges of Education in Anambra State, Nigeria and which constituted the sample for the study. The instrument for data collection was the Inventory of Cognitive Distortion – Youth Version (ICD-YV), validated by three experts. The reliability the instrument was established using Cronbach Alpha with coefficient of internal consistency of 0.82. The students’ CGPA in Biology were obtained from Course adviser folder whereas for ICD-YD was administered to the students with the help of the research assistants. The data obtained was analyzed using simple and multiple linear regressions. The findings of the study revealed among others that 31.5 percent of the variance in Biology achievement was predicted by students’ cognitive distortions. Furthermore, achievement in biology were significantly predicted by College of Education students’ cognitive distortions. The conclusion drawn from the findings of the study was that cognitive distortions is a significant predictors of academic achievement in Biology. It was recommended among others that, educators and school counselors should implement cognitive behavioural interventions to help students recognize and challenge irrational beliefs about their academic abilities.  
EFFECT OF MULTIMEDIA INSTRUCTION ON SECONDARY SCHOOL STUDENTS’ ACHIEVEMENT IN CHEMISTRY IN ENUGU EDUCATION ZONE
No full textThis research examined the impact of multimedia instruction on the academic performance of secondary school students in chemistry within the Enugu Education Zone. The study was guided by two research questions and three null hypotheses. A pretest-posttest non-equivalent control group quasi-experimental design was employed. The target population consisted of 1,577 Senior Secondary 2 (SS2) chemistry students in the Enugu Education Zone, from which a sample of 160 students was selected. Data were collected using the Chemistry Achievement Test (CAT), which was validated by three experts. The reliability of the CAT was determined using the KuderRichardson Formula 20, resulting in a reliability coefficient of 0.82. Over a six-week period, the experimental group was taught specific chemistry concepts using multimedia instruction (MI), while the control group received instruction on the same concepts through the lecture method (LM). Research questions were addressed using mean and standard deviation, and the null hypotheses were tested using analysis of covariance (ANCOVA). The results indicated that multimedia instruction significantly improved students\u27 chemistry achievement compared to the lecture method. Based on these findings, it was recommended that chemistry teachers, students, and curriculum developers integrate multimedia instruction as a teaching strategy, as it has proven more effective in enhancing students\u27 acquisition of science process skills and overall academic achievement in chemistry than the lecture method.

No full textThe researchers delved into the Perception of Science Education Students on the Availability and Usability of Technological tools in Teaching and learning at Nnamdi Azikiwe University Awka in the era of Insecurity and Economic Meltdown. Descriptive survey research design was employed in the study. The study was guided by four research questions. The population of the study was consisted of nine hundred and eighty-six (986) undergraduate regular students in the Department of Science Education. The sample for the study consisted of one hundred and twenty (120) students chosen using stratified sampling technique. The instrument for data collection was questionnaire titled Availability and Usability of Teaching and Learning Technological Tools (AUTLTT). The AUTLTT was validated by three experts from Faculty of Education in Nnamdi Azikiwe University Awka. The reliability of the instrument was established using Cronbach Alpha Reliability technique given a reliability coefficient of 0.78 The data were analysed using Mean Score. The findings revealed among others that majority of the technological tools are not available in teaching and learning of Science Education courses. Many challenges such as inadequate and lack of access to the technological tools, poor and epileptic power supply/ internet access, lack of trained personnel among others face the use of technology in teaching and learning of Science Education courses. The researchers equally made recommendation of funding both the Science Education Department and other servicing Departments for procurement of technological tools for effective teaching and learning. The University internet provider and power supply should equally be upgraded. In-service training for the use of these tools was also recommended among others by the researchers.

Enhancing Students’ Academic Engagement Through Team Work in Secondary School in Nigeria.
No full textEngagement among students is a crucial element in achieving academic success, especially in senior secondary where academic interest often declines as a result of several social and academic factors. This research investigates the effects of team work and collaborative assignments on students in Nigerian secondary education. The research study utilizes a descriptive survey methodology, gathering data from 200 educators across both public and private institutions through the use of questionnaires. The study indicates that collaboration encourages participation by fostering active involvement, responsibility, and interaction among team members. Group activities including discussions, problem-solving, creativity and competitive tasks were found to be the most effective in boosting student motivation and improving learning results. The data obtained from the questionnaires were analyzed using regression analysis with the Statistical Package for Social Sciences (SPSS) software. Collaborative learning among students led to enhanced academic performance, as they showcased improved retention, critical thinking abilities, and assessment outcomes when working together. Effective implementation is hindered by several challenges, including limited resources, unequal participation, and teachers struggling to manage group dynamics. These results highlight the necessity for a well-organized project management approach, comprehensive teacher training, and ample resources to fully capitalize on the rewards of collaborative learning. The study concludes that teamwork is a highly effective educational resource that boosts student participation and academic achievement. The recommendation suggests providing institutional backing, well-defined evaluation frameworks, and digital resources to enable collaboration. By promoting collaboration, Nigerian secondary schools can establish a dynamic and inclusive learning environment that equips students for future academic and professional.
