This study investigated the effect of Inquiry-Driven Collaborative
Learning enriched with ChatGPT (IDCL+ChatGPT) on pre-service teachers’
attitudes toward calculus in Kaduna State, Nigeria. Anchored on Social
Cognitive Theory, the study adopted a quasi-experimental pretest-posttest
non-equivalent control group design. The population comprised 1,122 NCE II
Mathematics students in public NCE-awarding institutions in Kaduna State, from
which 133 students were selected. Participants were assigned to IDCL+ChatGPT (n
= 53), IDCL-only (n = 45), and conventional teaching (n = 35) groups. Data were
collected using the Calculus Attitude Questionnaire (CAQ), validated by
experts, with a reliability coefficient of 0.811. Descriptive statistics
addressed the research questions, while ANCOVA and Bonferroni post hoc tests
tested hypotheses at the 0.05 significance level. Results revealed a
significant group effect on posttest attitude scores, F(2,129) = 27.630, p <
.001, partial η² = .300. Bonferroni comparisons showed that IDCL+ChatGPT
significantly outperformed conventional teaching (p < .001), while IDCL-only
also significantly outperformed conventional teaching (p < .001). However,
the difference between IDCL+ChatGPT and IDCL-only was not significant (p =
.071). The study concludes that IDCL effectively fosters positive attitudes
toward calculus, while ChatGPT provides additional instructional support that
enriches students’ learning experiences and supports meaningful classroom
interaction and engagement
