Abstract
This study aimed to develop a 5E Inquiry-Based Learning activity package combined with the Problem-Solving Process, focusing on the topic “Dirac Particle in a One-Dimensional Potential Well with Two Moving Walls”, for undergraduate physics students at Chiang Mai Rajabhat University. The objectives were to achieve an efficiency criterion of 75/75 and to enhance students’ Analytical Thinking Competency in the Quantum Mechanics course. The sample comprised 12 third-year physics students enrolled in the first semester of the 2024 academic year, selected through purposive sampling. Research instruments included the 5E learning activity package, an Analytical Thinking Competency assessment, an achievement test, and a student satisfaction questionnaire. Results showed that the activity package achieved an efficiency of 76.41/78.25, exceeding the standard criterion of 75/75. Students’ learning gain (g) was 0.76, indicating a high level of improvement and a significant enhancement in Analytical Thinking Competency. The 5E Inquiry-Based Learning approach enabled students to connect quantum concepts, analyze situations, and evaluate outcomes effectively. These results align with higher-order thinking levels of Bloom’s Taxonomy. In conclusion, the learning activities emphasized the development of Analytical Thinking Competency. The findings indicate that using the Problem-Solving Process on the Dirac particle in a one-dimensional potential well with two moving walls effectively promotes students’ progression from foundational understanding to higher-order thinking, supporting the goals of 21st-century learning.
