- Description: The depletion of the environment compelled researchers to investigate Environmental Education issues, the methods of imparting knowledge and the creation of awareness about environmental problems. However, youths have knowledge of environmental concepts but lack the skills, intentions, and action competence to exhibit positive environmentally responsible behaviour. There is, therefore, a need for a change in human behaviour to overcome current environmental problems. This study determines the effect of an environmental responsible behaviour intervention programme on Junior Secondary School learners in environmental education. It also explores the moderating effects of gender and school location. The study adopted a pre-test, post-test, control group and quasi-experimental design. A multi-stage sampling technique was employed. Eight (8) coeducational secondary schools in Ibadan, Nigeria, were selected based on environmental challenges in their immediate environment. There were four (4) schools from Ibadan city (urban area of Ibadan) and four (4) from Ibadan less city (rural area of Ibadan). Seven hypotheses were tested at a 0.05 level of significance. Five research instruments were used for this study. Analysis of Covariance (ANCOVA) was used in testing the seven formulated hypotheses. Estimated Marginal mean analysis was used to determine the source of significant effect of treatment. A significant interaction effect was described using a graphical representation. All hypotheses were tested at P< .05 level of significance. The result reveals that there was a significant main effect of treatment (Environmental responsible behaviour intervention programme on Junior Secondary School learners’ environmental knowledge (F(1,715) = 40.62, p < 0.05, Partial , 2 .054). There was also significant main effect of treatment (environmental responsible behaviour intervention programme on junior secondary school students’ environmental attitude. (F(1,715) = 32.36, p < 0.05. partial 2 = 0.043). The effect of treatment (Environmental responsible behaviour intervention programme) on students’ environmental practices was statistically significant, F(1,715) = 17.02, p < 0.05. partial 2 = 0.023). The findings shows that there was a significant main effect of school location (Urban and Rural) on Junior Secondary School students’ environmental knowledge (F(1,716) = 71.62 p< 0.05. partial 2 =0.091). There was no significant main effect of gender (male / female) F(1,715) =0.27, p> 0.05, partial 2 = 0.000. The findings further shows that there was significant main effect of school location on students’ environmental attitude, (F(1,175) =39.21, p< 0.05 partial 2 = 0.052) Shows that there was no significant main effect of gender on students’ environmental attitude F(1,715) =2.1, p> 0.05. partial 2 =0.003 There was significant main effect of school location on students’ environmental practices, F(1,715) = 17.02, p< 0.05 partial 2 = 0.019 but there was no significant main effect of gender on students’ environmental practices, (F(1,715) = 1.17, p> 0.05. partial 2 = 0.002). Based on these findings, it is recommended that teachers should use an environmental responsible behaviour intervention programme in teaching environmental concepts in the classroom. To support this, group/teamwork should be encouraged amongst students. Students should be allowed to construct knowledge in order to bring about their active participation with a view to making learning realistic and effective and to enable the exhibition of environmentally friendly behaviour. , Thesis (PhD)(Education)-- University of Fort Hare, 2021
