This study investigated student ideas surrounding the process of photosynthesis using an open-ended, two tier questionnaire. Past studies have shown that students of all ages and nationalities hold an alarming amount of misconceptions concerning photosynthesis, particularly when it comes to the origin of plant mass, the purpose of light and chlorophyll, and the products produced. In this study, ninth grade Biology students’ responses on a two-tier, four item questionnaire were analyzed against common misconceptions identified from literature and grouped by overarching themes pre- and post-unit. Results suggest that students were able to discard some of their misconceptions, but ultimately only developed low-level knowledge.
The purpose of this study is to help educators better address photosynthesis misconceptions that students bring to the classroom. This will allow educators to encourage deeper understanding of the processes involved in photosynthesis which may result in retained knowledge.
