Abstract

This research aims to reorganize the digital logic experiment-based teaching framework on the premise of fostering the ability of students to solve complex engineering problems. The reform is driven by three deep-seated challenges: the large difference between the cognitive abilities of students, the rigidity of verification-only exercises, and the prohibitive cost of trial-and-error with purely physical experimentation. In the new four-module incremental arrangement of the verification-design-comprehensive layers, mechanical wiring of preset diagrams is replaced by having students face a real trade-off when they choose devices. A synergy between the virtual and the real is achieved through a virtual-real loop, i.e., simulation comes first, followed by hardware. Evaluation was redesigned in parallel. Based on the theory of the Zone of Proximal Development (ZPD) by Vygotsky, a three-level optional grading system was designed. It works in combination with a “preparation -operation-summary” trilogy rubric and directs the evaluative focus onto pre-class scheme planning and fault-isolation behavior during offline experimentation. The evaluation initiative is then shifted to the students themselves, who are thereby motivated intrinsically. Three years of teaching experience obtained at Lingnan Normal University confirms the effectiveness of the reform. The students moved beyond mechanical assembly and developed substantial skills in the field of system-level architecture design and multi-objective trade-off reasoning.
