EFFECT OF JIGSAW COOPERATIVE LEARNING STRATEGY ON SECONDARY SCHOOL STUDENTS ACHIEVEMENT AND RETENTION IN ECOLOGICAL SUCCESSION IN BIOLOGY

This study investigated the effect of the Jigsaw Cooperative Learning Strategy (JCLS) on secondary school students' achievement and retention in Ecological Succession in Biology. The study adopted the quasi- experimental pretest-posttest, non-ramdomized non-equivalent control group design. The study was guided by five research questions and five corresponding null hypotheses, which were tested at a 0.05 level of significance. The population for the study consisted of all senior secondary school students in public schools in Egor Local Government Area of Edo State, Nigeria. The instruments used for data collection were the Biology Achievement Test on Ecological Succession (BATES) and the Biology Retention Test on Ecological Succession (BRTES), both of which consisted of 25 multiple-choice questions which were drawn from the West Africa Senior School Certificate Examination past questions. Data collected were analyzed using mean, standard deviation, t-test, independent sample t-test and Analysis of covariance (ANCOVA).
