From screen to bench: unpacking the shifts in chemistry learning experiences during the COVID-19 transition

This research comprehensively analyzes students' Chemistry Learning Experience (CLE) during the COVID-19 pandemic, comparing online learning experiences with traditional face-to-face instruction in the post-pandemic phase. Employing a quantitative approach and leveraging the Rasch model, the study focuses on capturing the nuances of individual student perceptions, an aspect often overlooked in group-centric statistical analyses. One hundred students (49 males and 51 females) participated in both study phases. Segmented into behavioral tendencies, content perceptions, and specific learning needs, the evaluation tools provided insights into the students' CLE across the two instructional modalities. Results from the stacking analysis revealed a positive shift in CLE post-pandemic, with students demonstrating a better grasp of and attitude toward chemistry in face-to-face settings. Racking analysis further underscored the changing difficulty perceptions of specific content items across the two learning environments. Gender-based patterns in CLE were also evident, with male students expressing a more favorable view of online learning during the pandemic than their female counterparts. The research findings advocate for a blended learning approach, harnessing the strengths of both online and traditional instructional methods. Furthermore, insights into gender-specific learning experiences emphasize the need for inclusive and adaptive teaching strategies, ensuring optimal learning experiences for all students. The study underscores educators' and students' resilience and adaptability in navigating the challenges of the pandemic. It offers valuable insights for future educational strategies in chemistry education.
