Using computer-assisted instruction to improve students’ performance in some selected biology topics at Odupong Senior High School

Abstract

The study investigated the effect of using computer-assisted instruction in teaching selected Biology topics on performance of SHS 2 Biology students at Odupong Senior High School located in the Awutu Senya East Municipality. One research question and two hypotheses guided the study. The selected biology topics from the biology teaching syllabus were reproductive system, nervous system (control and coordination), respiratory system, excretory system, skeletal system and body symmetry and orientation. The researcher used computer-assisted instruction (CAI) as an intervention tool in this study. The pre-test was administered before treatment while a post-test was administered after the treatment. A questionnaire was used to collect students’ views on the use of CAI on the selected topics. Descriptive statistics were used to organise the scores into mean scores and standard deviations and used to answer the one research question that guided the study. Independent samples t-test was used to test two hypotheses stated. The study indicated a difference in mean achievement scores between the students taught using computer-assisted instruction and those taught using the lecture method. The findings of the study suggested that computer-assisted instruction was a better alternative to lecture methods in teaching selected biology topics. The students expressed positive views about the use of Computer-Assisted Instruction (CAI) in Biology lessons. They noted that CAI significantly improved their critical thinking skills in biology, resulting in a better understanding of complex biology concepts. CAI was also seen to enhance students' understanding and engagement, leading to a better grasp of complex biology concepts and increased motivation in learning biology. Additionally, CAI provides personalized learning experiences tailored to individual students' needs and learning styles. Other benefits of CAI mentioned by the students include its ability to provide real-time feedback and assessment, enabling students to track their progress. CAI can also supplement traditional instruction, providing students with an interactive and engaging learning experience. Therefore, a computer-assisted instruction approach is recommended for teaching biology topics at the senior high school level.
