Key Points

To evaluate whether teacher-curated AI-assisted representational presentations enhance student motivation, curiosity, and chemistry achievement compared to traditional classroom demonstrations.
Quasi-experimental study of 120 grade 9 students across four intact classes in one middle school, categorized as typical or struggling learners based on prior science achievement.
Compared teacher-led classroom demonstrations (prediction, observation, explanation) against teacher-curated AI presentations that simultaneously displayed macroscopic, particulate, and symbolic representations.
Maintained identical curriculum, instructional time, teacher, and postunit assessments, followed by moderated mediation analysis.
Students in the teacher-curated AI presentation condition achieved significantly higher chemistry postunit scores than those in the classroom demonstration condition, with the greatest gains seen among struggling learners.
Moderated mediation analysis confirmed that increases in student learning motivation and scientific curiosity partially mediated the positive relationship between the presentation intervention and chemistry achievement.
