EFFECTS OF E-LEARNING STRATEGIES ON STUDENTS' INTEREST, ACADEMIC ACHIEVEMENT, AND RETENTION IN ELECTRICAL MACHINE WINDING IN GOVERNMENT SCIENCE AND TECHNICAL COLLEGES OF ADAMAWA STATE, NIGERIA

The purpose of the study was to investigate the effects of e-learning method on students’ interest, academic achievement, and retention, and Electrical Machine Winding in Government Science and Technical Colleges (GSTCs) of Adamawa State. The study was guided by 10 specific objectives, seven research questions, and nine null hypotheses. The study which was conducted in Adamawa State adopted a pre-test, post-test, non-equivalent control group, quasi-experimental research design. The population of the study comprised the entire 158 EIMW trade students in NTCII as of the 2024/ 2025 academic session in the three GSTCs. A sample size of 92 students from two GSTCs intact classes formed the sample for the study. Simple random sampling technique was applied to select the GSTCs, assigned to experimental or control group. The study used separate instruments for data collection namely: achievement test instrument tagged “Electrical Machine Winding Achievement Test (EMWAT)” and a structured questionnaire titled “Electrical Machine Winding Practice Student’ Interest Scale (EMWPSIS)”. EMWAT was subjected to both content and face validation while EMWPSIS was faced validated. A reliability index of 0.85 was obtained for EMWAT using Kuder-Richardson Formula-21 (KR-21) whereas Cronbach's Alpha was used to determining the reliability of EMWPSIS and 0.86 obtained. Pre-test, Post-test and Retention test were administered to the students.  Mean and Standard deviation were used to answer the research questions, while the hypotheses were tested using Mann-Whitney U Test and Analysis of Covariance (ANCOVA) at a 0.05 level of significance. The findings of the study revealed that there is a significant difference between the mean scores of students taught electrical machine winding using e-learning and demonstration teaching methods in GSTCs of Adamawa State. There is a significant difference between the mean scores of students taught electrical machine winding based on gender using e-learning and demonstration teaching methods in GSTCs of Adamawa State.  There is a significant interaction effect between teaching method and gender on the mean academic achievement scores of students taught electrical machine winding in GSTCs of Adamawa State. The study further reveled that there is a significant difference between the mean retention scores of students taught electrical machine winding using e-learning and demonstration teaching methods in GSTCs of Adamawa State. The study recommended among others, that, curriculum planners and instructional designers should integrate e-learning methodologies into the teaching of EIMW and other technical subjects to enhance students’ academic performance and ensure deeper understanding of concepts; Teachers in GSTCs should adopt e-learning tools and platforms such as simulations, animations, and interactive tutorials, as they have been shown to significantly boost student achievement and retention; The Ministry of Education and relevant stakeholders should train technical teachers on the effective use of digital instructional technologies and e-content creation, ensuring uniform adoption of e-learning practices across schools.
