Abstract

This study investigated discovery learning pedagogy and its effects on students’ achievement and attitudes toward instruction in a lower-division biology course, entitled Structure and Function of Organisms. Instruction was primarily lecture-based but included four discovery learning activities. Results indicate that students had greater achievement on content learned through discovery methods than lecture-based instruction. Findings regarding students’ attitudes toward discovery-based instruction suggest that students enjoyed active, discovery-based problems, believed that discovery helped them gain an understanding of the material and helped them to develop skills that could be used in other courses. The study presented here shows that a moderate amount of discovery learning used in combination with traditional methods of instruction may be an effective means for promoting students’ achievement.

Key words: discovery-based instruction
