Analysis of the effectiveness of inquiry-based learning on high school biology achievement and attitudes toward science across diverse urban and rural classrooms

Project Abstract

This study investigates the impact of inquiry-based learning (IBL) on high school biology achievement and students’ attitudes toward science across diverse urban and rural classrooms. The research employs a quasi-experimental mixed-methods design over an academic year in six public high schools, with three urban and three rural sites, to examine whether IBL strategies produce differential gains in test scores and attitudinal measures compared to traditional teacher-centered instruction. A total of approximately 1,200 biology students across grades 9–12 are included, with intact intact classes assigned to either the experimental IBL condition or the control condition. The IBL intervention integrates structured, student-driven investigations, experimental design, data collection and analysis, collaborative discourse, and iterative feedback aligned with the national science standards and district benchmarks. Data sources include standardized biology assessments, unit-specific performance tasks, validated attitudinal surveys, classroom observations, and semi-structured interviews with students and teachers. Baseline data were collected prior to the intervention to ensure equivalence across groups, followed by mid-term and end-of-year assessments to track progress. Quantitative analyses employ multilevel modeling to account for clustering by classroom and school, enabling estimation of main effects of condition, setting (urban vs. rural), and their interaction on achievement and attitudinal outcomes, as well as growth trajectories over time. The qualitative component uses thematic analysis of interview transcripts and observation field notes to elucidate mechanisms by which IBL influences learning processes, including inquiry skills development, conceptual understanding, motivation, self-efficacy, and perceptions of science relevance. The study also explores potential moderating factors such as teacher facilitation quality, resource availability, class size, and prior achievement levels. Findings indicate that students in the IBL condition exhibit statistically significant gains in biology achievement relative to peers in traditional instruction, with effect sizes varying by setting. Urban students show larger gains in inquiry reasoning and data interpretation, while rural students demonstrate notable improvements in scientific communication and collaborative problem-solving. Attitudinal shifts favor positive views toward science, increased interest in pursuing STEM-related activities, and higher self-efficacy in conducting experiments, particularly among students who experienced structured scaffolds and explicit metacognitive prompts. The research identifies critical instructional elements that mediate success, including explicit hypotheses formulation, guided inquiry scaffolds, opportunities for authentic data collection, peer collaboration norms, and formative feedback cycles. Implications for practice highlight the need for professional development focused on inquiry facilitation, equitable access to laboratory resources, and culturally responsive instructional design to maximize the benefits of IBL across diverse educational contexts. Limitations address potential confounds such as differential teacher experience with IBL, variability in school schedules, and the fidelity of intervention implementation. The study contributes to the literature on science education by providing robust, context-sensitive evidence of IBL’s efficacy in both urban and rural settings and offers practical recommendations for scaling evidence-based inquiry practices in public high schools.

Project Overview

What This Project Is About

---

This project looks at how teaching biology through inquiry-based learning (IBL) affects what high school students know and how they feel about science, comparing urban and rural classrooms.

---

---

The Problem It Addresses

---

Many schools rely on traditional lectures, which can limit student curiosity and long-term understanding. It’s unclear whether IBL helps students in different settings equally, and whether attitudes toward science change with this approach.

---

---

Objectives of the Project

---

1. Compare biology achievement between IBL and traditional teaching methods.
2. Assess changes in students’ attitudes toward science after IBL exposure.
3. Examine differences in effects between urban and rural classrooms.
4. Identify practical challenges and supports for implementing IBL in diverse settings.

What You Will Do Step by Step

---

1) Review literature on IBL and biology learning. 2) Select urban and rural classrooms and assign teaching methods. 3) Design and administer pre- and post-tests to measure achievement. 4) Use a survey to gauge attitudes toward science. 5) Collect classroom observations and teacher reflections. 6) Analyze data for achievement gains and attitude shifts, with comparison by setting. 7) Discuss findings and limitations. 8) Propose practical guidelines for IBL implementation.

Expected Outcome

We expect higher biology scores and more positive attitudes toward science among students taught with IBL, with potential differences between urban and rural groups. The study should offer actionable guidance for teachers and schools seeking to adopt IBL effectively.
