Effects Of Collaborative Learning And Individualized Instructional Methods On The Academic Achievement And Retention Of Secondary School Biology Students In Abia State

ABSTRACT

This study investigated the effects of collaborative learning and individualized instructional methods on the academic achievement and retention of secondary school Biology students in Abia State. The study was guided by six research questions and six null hypotheses. The related literature for this study was reviewed in four sections; conceptual framework, theoretical framework, empirical studies and summary of literature review. Quasi experimental research design was adopted for this study. Specifically, non-equivalent control group research design was used. The study was carried out in Abia State. It is one of the five South Eastern States in Nigeria with 17 Local Government Areas. Abia State is located approximately within latitude 4⁰40ʹ and 6⁰14ʹ North and longitude 7⁰10^ʹ and 8⁰ East. The population of the study comprised 13,306 SSII Biology students (6,415 males and 6,891 females) in 2020/2021 academic session. A sample of 115 SSII Biology students consisting of 54 males and 61 females was drawn in multi stages using purposive and simple random sampling techniques. Biology Achievement Test (BAT) adapted from past WAEC questions was used for data collection. The instrument was validated by three experts; one in measurement and evaluation and two in Biology education, all in the Department of Science Education, Michael Okpara University of Agriculture, Umudike. The instrument was subjected to reliability test using Kuder Richardson 20 (KR₂₀) test statistics, and a reliability coefficient of 0.78 was obtained. Mean and standard deviation were used to answer the research questions while the null hypotheses were tested using Analysis of Covariance (ANCOVA) at 0.05 level of significance. Findings from the study showed that students taught Biology using collaborative learning method achieved higher than those taught with individualized instructional method. Students taught Biology with individualized instructional method recorded higher level of retention than those taught using collaborative method. Furthermore, there was no significant difference in the academic achievement of male and female students exposed to collaborative learning method. However, significant difference existed in the academic achievement of male and female students taught Biology with individualized method in favour of the males. The findings also indicated that there was no significant difference in the retention of male and female students taught Biology with both collaborative learning and individualized instructional methods. Based on the findings of the study, it was recommended that Biology teachers should use collaborative learning and individualized instructional methods in the process of teaching and learning for high academic achievement and retention. It was also recommended that male and female students be encouraged to study together in groups so as to learn from each other.
