Evaluating the effectiveness of inquiry-based learning modules on sustainable terrestrial ecosystem literacy among high school biology students.

Project Abstract

This study investigates the effectiveness of inquiry-based learning (IBL) modules in enhancing sustainable terrestrial ecosystem literacy among high school biology students. Employing a quasi-experimental design, the research compared an intervention group engaged with structured IBL modules against a control group taught via traditional teacher-directed instruction over a 12-week period in three public high schools. The IBL modules were developed around core concepts of ecosystem structure, function, sustainability, and human-environment interactions, and incorporated student-led investigations, data collection and analysis, hypothesis formulation, evidence-based reasoning, and reflective discourse. A mixed-methods approach was used to capture both quantitative and qualitative outcomes. Quantitative measures included pre- and post-tests assessing content knowledge, critical thinking skills, and attitudes toward sustainability, as well as a performance-based assessment using authentic tasks such as ecological audits, data interpretation of field datasets, and collaborative problem-solving scenarios. Reliability of instruments was established through Cronbach’s alpha and test-retest analyses, while validity was supported by content review by biology educators and pilots with students. Qualitative data were gathered through classroom observations, student interviews, and focus groups to explore changes in scientific inquiry skills, motivation, and sense of responsibility toward environmental stewardship. Data analysis employed ANCOVA to control for initial differences, effect size calculations (Cohen’s d), and thematic analysis of transcripts to identify recurring patterns in inquiry practices and conceptual understanding. Results indicate that students exposed to IBL modules demonstrated statistically significant gains in ecosystem literacy, including enhanced understanding of biotic and abiotic components, trophic interactions, ecosystem services, and the concept of sustainability as a dynamic, human-influenced process. The intervention group also showed superior performance on complex tasks requiring data-driven reasoning, hypothesis generation, and collaborative problem-solving, with medium to large effect sizes. Qualitative findings corroborated these outcomes, revealing increased student autonomy, engagement in field-based investigations, more frequent use of evidence to justify claims, and higher classroom discourse quality characterized by argumentation and peer feedback. The study also identified key factors moderating effectiveness, such as structured scaffolding, authentic field experiences, teacher professional development in inquiry facilitation, and alignment of modules with national biology standards and local ecological contexts. Limitations include potential selection bias due to non-random assignment, variability in teacher implementation fidelity, and constraints of school schedules limiting long-term assessment. Implications for practice suggest that scaling IBL-based modules requires comprehensive teacher training, adaptable module kits, and integrated assessment frameworks that value process skills alongside content mastery. Policy recommendations emphasize incorporating inquiry-based science teaching into curricula to promote sustainable literacy as a core outcome of biology education. The findings contribute to the growing evidence base that inquiry-based learning can meaningfully elevate students’ understanding of terrestrial ecosystems and their capacity to engage in informed, responsible environmental decision-making.

Project Overview

What This Project Is About

---

This project explores whether using inquiry-based learning (IBL) methods helps high school biology students understand and appreciate sustainable terrestrial ecosystems. It compares traditional teaching with IBL activities that guide students to investigate real-world ecosystem issues, collect data, and draw evidence-based conclusions.

The Problem It Addresses

---

Many students struggle to connect biology concepts to real-world environmental challenges. Teachers often rely on lectures, which can limit curiosity and critical thinking. This project investigates whether IBL can improve students’ literacy about ecosystems and their ability to apply knowledge to sustainability decisions.

---

Objectives of the Project

---

1. Assess changes in students’ understanding of sustainable terrestrial ecosystems after IBL activities.
2. Evaluate improvements in scientific inquiry skills, such as forming questions, collecting data, and drawing evidence-based conclusions.
3. Compare student engagement and attitudes toward biology between IBL and traditional instruction.
4. Identify practical challenges and facilitators of implementing IBL in a typical high school setting.

What You Will Do Step by Step

---

1. Review relevant literature on inquiry-based learning and ecosystem literacy.
2. Design a unit with clearly defined IBL activities centered on local terrestrial ecosystems.
3. Recruit classes and obtain necessary permissions.
4. Implement the IBL unit alongside a traditional teaching unit in separate classes.
5. Collect data through quizzes, project rubrics, and student reflections before and after.
6. Analyze data to measure gains in understanding and inquiry skills.
7. Compare results between instructional approaches and identify factors influencing outcomes.
8. Prepare a concise report highlighting findings and recommendations for practice.

Expected Outcome

The project is expected to show that IBL improves ecological literacy and inquiry abilities more than traditional methods, with higher student engagement and confidence in applying biology to real-world sustainability issues. Findings could guide teachers on practical steps to adopt IBL in biology curricula.
