Abstract :This study examines the impact of the PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) method on academic intrinsic motivation in science education. The PDEODE method fosters a meaningful and engaging learning environment through enhancing students\\\' interactions with science. The research was conducted with 38 pre-service science teachers at a public university in Türkiye. Over six weeks, students participated in chemistry laboratory activities based on the PDEODE method, and their motivation levels were assessed before and after implementation using the Academic Intrinsic Motivation Scale (AIM). The findings indicated that PDEODE activities significantly enhance students\\\' academic intrinsic motivation. Statistically significant improvements were detected in the motivational dimensions of need for achievement, perceived expertise, and social acceptance. Additionally, laboratory activities facilitated the improvement of students’ experimental skills, reinforced their self-confidence, and encouraged a more positive attitude toward failure. The discussion stages were found to encourage students to express their thoughts more confidently, thereby strengthening their motivation. In conclusion, the PDEODE method emerges as an effective instructional model that not only enhances students’ scientific thinking skills but also increases their motivation. This study highlights PDEODE as an innovative method to science education and offers insights into developing teaching strategies that enhance students\\\' engagement with scientific concepts.
