Construction and Practice of Virtual Simulation Experiment Teaching System for Concrete Rebound Test

Abstract

As a core experimental project in the courses of civil engineering materials and structural inspection, the concrete rebound test is faced with such pain points in traditional physical experiments as shortage of hardware resources, high cost of specimen preparation, difficulty in reproducing extreme working conditions, single teaching mode, and lack of process assessment. Guided by the training of new engineering talents, this paper constructs a five-in-one virtual simulation experiment teaching system for concrete rebound test, namely “objective-content-platform-implementation-evaluation”. This system integrates the virtual-real combination teaching mode, task-driven and gamified interaction methods, restores the whole process of on-site engineering inspection relying on the virtual simulation platform, and breaks through the temporal, spatial and conditional constraints of physical experiments. Teaching practice has verified that this system effectively improves students’ experimental operation ability, data analysis and critical thinking, optimizes the allocation of experimental teaching resources, and provides a replicable practical path for the teaching reform of virtual simulation experiments of civil engineering materials.
