结构力学线上线下混合式教学模式的创新实践与成效分析

Innovative Practice and Effectiveness Analysis of an Online-Offline Blended Teaching Model for Structural Mechanics

摘要: 针对结构力学课程理论性强、概念抽象、计算复杂，传统单一课堂讲授模式难以满足现代工程教育需求的问题，本研究深度融合现代信息技术，创新性地构建了“线上资源自主奠基 + 线下课堂深度内化 + 虚实结合实践强化”的三阶递进式线上线下混合教学模式。通过系统建设微课视频、BIM动态演示、交互式仿真实验等线上资源，实施基于问题导向的翻转课堂、小组协作建模分析等线下教学活动，并融入虚拟仿真实验平台进行结构行为探究。实践表明，该模式显著提升了学生的知识掌握水平、空间思维能力、工程实践能力及自主学习积极性，有效解决了教学痛点，为工科核心课程的混合式教学改革提供了可借鉴的范式。

Abstract: To address the challenges in structural mechanics courses—characterized by strong theoretical foundations, abstract concepts, and complex calculations—where traditional single-mode lecture-based teaching falls short of meeting modern engineering education demands, this study deeply integrates modern information technology. It innovatively establishes a three-phase progressive online-offline blended teaching model: “Self-paced Online Foundation Building + In-depth Classroom Internalization + Virtual-Physical Integration for Practice Reinforcement.” Through systematically developing online resources such as micro-lecture videos, BIM dynamic demonstrations, and interactive simulation experiments, while implementing offline activities including problem-based flipped classrooms and group collaborative modeling analysis, the model further incorporates virtual simulation platforms for structural behavior exploration. Practice demonstrates that this approach significantly enhances students’ knowledge mastery, spatial thinking ability, engineering practice skills, and self-directed learning motivation, effectively resolving key instructional challenges. This provides an actionable paradigm for blended teaching reform in core engineering courses.
