Abstract

The study investigated the effect of Think-Pair-Share instructional strategy on Senior Secondary Two students’ achievement in Genetics in Abuja, Nigeria. The study adopted a non-randomized pre-test, post-test quasi-experimental research design. The population of the study consisted of 1,100 Senior Secondary Two (SS2) Biology students. A sample of 224 Biology students drawn from four co-educational senior secondary schools in Abuja (two public and two private schools) was used for the study. Two research questions and two hypotheses guided the study. The Think-Pair- Share instructional strategy was used to teach the experimental group, while the lecture method was used for the control group. The instrument used for data collection was the Students’ Genetics Achievement Test , with a reliability coefficient of 0.99 established using the Cronbach Alpha method. Data collected were analyzed using the Statistical Package for Social Sciences . Mean and standard deviation were used to answer the research questions, while Analysis of Covariance was used to test the hypotheses at 0.05 level of significance. The findings revealed a significant difference between the achievement mean scores of students taught Genetics using the Think-Pair-Share strategy and those taught using the lecture method, in favour of the experimental group. With respect to gender, there was no significant difference between the achievement mean scores of male and female students taught Genetics using the Think-Pair-Share strategy. Based on the findings, it was concluded that the Think-Pair-Share instructional strategy improved students’ achievement in Biology, particularly Genetics. It was therefore recommended, among others, that Biology teachers should incorporate the Think-Pair-Share strategy into their instructional practices for teaching Biology concepts, especially Genetics.
