Evaluating a Novel Instructional Sequence for Conceptual Change in Physics Using Interactive Simulations

This study investigated the effectiveness of a novel inquiry-based instructional sequence using interactive simulations for supporting students' development of conceptual understanding, inquiry process skills and confidence in learning. The study, conducted in Beijing, involved two teachers and 117 students in four classes. The teachers participated in professional learning and were supported in enacting one of two different instructional approaches the Interactive Simulations Instructional Approach (ISIA) (experimental group) or conventional instruction (control group). Each student group completed pre-tests and post-tests, and classroom observations were conducted to ensure that the implementation of the intervention was consistent. Our findings reveal that students in the ISIA group demonstrated significantly greater gains in conceptual understanding, inquiry process skills and confidence in learning than their peers in the conventional instruction group. Neither students' sex nor their levels of academic achievement showed main effects on students' achievement in any of the three outcome types (understanding, skill, confidence). This study demonstrates that the combination of interactive simulations and inquiry-based learning can enhance the development of students' conceptual understanding, inquiry process skills and confidence in learning.
