Improving Learning Outcomes (LO) in Engineering Design with ADAMFATIH:
A Gui-Based Simulation Tool
Abstract
This study introduces ADAMFATIH, a graphical user interface (GUI) developed to support learning in pipeline integrity and fatigue design within the MEC531 Design 1 course. Grounded in industry standards like ASME B31G and DNV-RP-F101, the tool allows students to simulate calculations, visualise outcomes, and grasp multi-step design concepts through an interactive, cause-and-effect feedback loop. Methodologically, the study employed a within-subject quasi-experimental design involving 23 third-year engineering students. The intervention utilised a mixed-methods approach, assessing effectiveness through pre- and post-tests, perception surveys, and semi-structured interviews analysed via thematic analysis. Results demonstrated significant improvements in student performance following the intervention (t(22) = 3.42, p < 0.01; Wilcoxon Z = -3.15, p < 0.01; d = 0.71). These findings confirm that the ADAMFATIH GUI had a statistically significant and meaningful impact on learning outcomes. Qualitatively, perception surveys confirmed high usability and pedagogical value (α=0.83). Furthermore, thematic analysis of student interviews revealed that the tool effectively provided instant error visualisation, reduced design anxiety by lowering cognitive load, and fostered a preference for active peer instruction over traditional lecture formats. These findings suggest the potential for integrating GUI-based simulation tools in technical engineering modules to enhance learning outcomes in specific, technically intensive domains.
