Effect of Team–Based Learning Strategy on Senior Secondary School Biology Students' Academic Achievement in Ecology in Abeokuta Metropolis, Ogun State

A fluctuating trend is noticeable in WAEC Biology results in Ogun State in recent time due to persistent challenges in critical thinking and real-world application of ecological concepts. This informed this study on the Effect of Team-based Learning (TbL) Strategy on Senior Secondary School Students’ Academic Achievement in Ecology in Abeokuta Metropolis, Ogun State. Guided by a hypothesis (α<0.05), a pretest-posttest quasi-experimental design was employed, where a sample of 58 students from two purposively selected public secondary schools participated in the sample. A validated instrument, Ecology Achievement Test (EAT) (KR-20 = 0.76) was used for data collection and tested using Analysis of Covariance (ANCOVA). There was a significant effect of Team–based learning strategy on senior secondary school students’ academic achievement in Ecology in Abeokuta Metropolis, Ogun State [F(1, 55) = 160.770, p < 0.05, η² = 0.745]. Based on the result, the study concludes that Team–based learning strategy significantly improves students’ academic performance in Ecology and recommends its broader adoption in teaching Ecology and other sciences.
