Instruction Based on Inquiry

Abstract

This chapter examines instruction based on inquiry as a pedagogical framework rooted in constructivist principles, positioning learners as active agents in the construction of knowledge. Drawing from historical, philosophical, and psychological foundations, the authors trace the evolution of student-centered learning from Socratic dialogue to constructivist theories. Four instructional models, inquiry-based learning, problem-based learning, project-based learning, and case-based learning, are analyzed with respect to their underlying assumptions, instructional design, and levels of guidance. While all formats share constructivist tenets such as social negotiation, prior knowledge activation, and meaningful tasks, they differ in implementation, learner autonomy, and pedagogical goals. The chapter synthesizes findings from recent meta-analyses (2020-2025), demonstrating generally positive effects of these formats on knowledge acquisition, critical thinking, and student motivation, though methodological concerns persist. The authors highlight conceptual ambiguities in the literature and argue for greater precision when defining instructional methods. Future research is encouraged to move beyond the binary question of “what works” and instead examine the mechanisms, contexts, and learner characteristics that make inquiry-based instruction effective. The chapter concludes by advocating for thoughtfully designed hybrid approaches that integrate the strengths of both direct and inquiry-based instruction.
