Comparative Analysis of Inquiry-Based Learning Effects in Urban and Rural Science Classrooms

Thesis Abstract

The effectiveness of inquiry-based learning (IBL) strategies in enhancing scientific understanding among students varies notably across different socio-geographical contexts, yet comparative analyses between urban and rural settings remain limited. This study investigates the differential effects of inquiry-based learning on science achievement, critical thinking skills, and attitudes towards science in urban and rural secondary school classrooms. The primary aim is to examine whether the implementation of IBL produces significant differences in these outcomes between urban and rural students, thereby informing tailored pedagogical strategies and policy formulations. Specific objectives include comparing science achievement levels post-intervention, assessing changes in critical thinking abilities, and exploring students’ attitudes towards science before and after exposure to IBL strategies in both settings. The study employed a quasi-experimental pretest-posttest control group design involving a total of 600 students from six secondary schools (three urban and three rural), selected through stratified random sampling to ensure representativeness. The experimental groups received instruction guided by inquiry-based learning modules integrated with the constructivist framework, grounded in Vygotsky’s Social Development Theory, while control groups continued with traditional teacher-centered instruction. Data collection instruments included standardized science achievement tests, the California Critical Thinking Dispositions Inventory (CCTDI), and a Science Attitudes Questionnaire (SAQ). Validity and reliability of instruments were established through content expert reviews, pilot testing, and calculation of Cronbach’s alpha coefficients exceeding 0.80 for all measures. Data analysis involved descriptive statistics to profile demographic variables, followed by inferential techniques including multivariate analysis of variance (MANOVA) to test the hypotheses concerning differences in post-test scores between urban and rural groups, controlling for pre-test scores. Thematic analysis was employed on open-ended survey responses to explore qualitative insights into students’ attitudes, while regression analysis identified predictors of science achievement and critical thinking enhancements attributable to IBL. Expected findings suggest that inquiry-based learning significantly improves students' science achievement, critical thinking skills, and attitudes towards science in both settings; however, the magnitude of these improvements is hypothesized to be greater among students in urban schools due to higher resource availability and teacher training levels. Notably, urban students are expected to exhibit more positive attitudes and higher gains in critical thinking, whereas rural students may demonstrate initial lower baseline levels but comparable growth trajectories when subjected to IBL strategies. This research contributes novel insights into the differential impact of inquiry-based pedagogies across socio-economic and geographic contexts, expanding the theoretical discourse on constructivist learning frameworks in diverse educational environments. It underscores the importance of contextualized instructional design and provides empirical evidence supporting the adaptation of IBL approaches to maximize learning outcomes for varied student populations. The main conclusion emphasizes that inquiry-based learning is an effective pedagogical approach across both urban and rural science classrooms, but its implementation must consider contextual infrastructural and instructional constraints to realize equitable educational benefits. Consequently, it is recommended that policymakers and educational practitioners invest in targeted professional development programs, resource provisioning, and context-sensitive curriculum modifications to enhance the efficacy of inquiry-based science education universally. Future research is suggested to explore longitudinal effects of IBL and to include other socio-cultural variables influencing learning outcomes, thereby further enriching the understanding of constructivist pedagogies in diverse educational landscapes.
