Abstract

The iBEARS (Biologists Experiencing Active Research with Students) program is a STEM intervention that develops STEM interest in middle school students. A quasi-experimental pre-post design compared 81 students in intervention and control groups using surveys measuring three types of situational interest. A repeated measures ANOVA showed a significant time effect for triggered interest, indicating increased curiosity across all students. Intervention participants reported significantly higher situational interest than controls. No differences were found for maintained value, and gender did not moderate outcomes. Findings suggest that integrated STEM instruction can enhance curiosity and emotional engagement, supporting early interest development. Results underscore the importance of developmentally aligned STEM experiences in classroom settings.
