Building upon the study titled "Enhancing Imagination and Understanding of Beam Deformations Through a Graphic Tool," this research investigates the progression of students' comprehension of statically determinate beam deformations. The study employs a series of four surveys (S1 to S4) conducted in 2024 to assess students' ability to accurately depict beam deflection curves. By categorizing errors into three main types and tracking individual progress across three key surveys (S1, S2, and S4), the study identifies patterns of improvement and persistent misconceptions. The introduction of a graphic tool after S1 and S2 significantly enhanced students' understanding, particularly in recognizing fixed-end behavior, deflection continuity, and rigid body deformation. However, challenges remained, especially in the case of distributed load spanning an intermediate support. The findings emphasize the effectiveness of iterative learning and visual aids in structural engineering education, highlighting the need for continued reinforcement of complex structural concepts. This research contributes to the development of pedagogical strategies that improve conceptual grasp and problem-solving skills in engineering students, demonstrating the value of interactive tools in facilitating learning outcomes.
