Resumen
This study described the implementation procedure (step-by-step) of the culturo-techno-contextual approach (CTCA) in the classroom with concrete curricular examples for each step. The study then proceeded to explore the potency of CTCA on nuclear chemistry, a traditionally perceived difficult concept among secondary school students in Nigeria, as obtained from the survey phase of the study. Using a quasi-experimental research design, we had a total of 221 senior secondary school two (SS2, the equivalent of grade 11) students from two schools in educational district V of Lagos State, Nigeria, who participated in the experimental phase of the study. After the pretest exercise for both the experimental and comparison groups, we had a four-week treatment where the experimental group was taught with CTCA, and the comparison group was taught with the conventional lecture method. Four weeks after the posttest, a retention test was conducted for both groups using the same Nuclear Chemistry Achievement Test instrument used for the pre- and posttests. Data collected were analyzed using ANCOVA, and the results obtained showed a statistically significant mean difference between the groups [F(1, 218) = 84.12; p < 0.05], indicating that CTCA improved students’ performance in nuclear chemistry. We also found no statistically significant difference in the achievement of male and female students in the experimental group. Within the limitations of the study, we concluded that CTCA is a viable culturally relevant tool for teaching chemistry concepts. The future directions of the study were also highlighted.
