Abstract
Quantum physics is inherently abstract, often leading students to perform mechanical calculations while losing the underlying conceptual meaning. To achieve deep understanding, students require representational flexibility. This study aims to develop a Computational Thinking (CT)-based e-worksheet and investigate its effectiveness in enhancing the deep understanding of quantum mechanics. Employing the ADDIE instructional design model, a pre-experimental one-group pretest-posttest study was conducted involving 34 final-year pre-service physics teachers. The e-worksheet was evaluated by seven experts using the Learning Object Review Instrument (LORI). Deep understanding was measured using an 18-item test grounded in Ainsworth^s multiple representations framework, focusing on the cognitive transitions between mathematical, graphical, and verbal formats. The test exhibited excellent content validity (Aiken^s V = 0.91) and reliability (0.872). Expert evaluation using LORI yielded an outstanding mean score of 4.65 out of 5.00, confirming the e-worksheet^s high feasibility and robust content quality. Implementation results revealed a substantial increase in students^ mean scores, rising from 26.63 to 69.77. The intervention achieved a moderate yet highly meaningful normalized gain (N-gain = 0.59). Furthermore, a Bayesian Paired Samples T-Test provided decisive evidence (\(BF_{-0} = 5.898 \times 10^{20}\)) supporting the instructional impact of the product. The integration of CT systematically guided students to preserve conceptual meaning across different representations. In conclusion, the CT-based e-worksheet is a highly valid and decisively effective pedagogical tool for fostering representational flexibility and enhancing students^ deep understanding of quantum physics.
