基于AI和模拟招投标的数电第二课堂教学实践探索

An Exploratory Study on Second-Classroom Teaching Practice for Digital Electronics Courses Based on AI and Simulated Bidding

摘要: 针对当前数字电子技术课程教学中学生实践能力培养不足、人工智能工具使用缺乏有效引导等问题，基于成果导向教育理念，提出在数字电子技术第二课堂中引入模拟招投标机制和AI辅助工具的教学改革方案。以基本数字逻辑电路的设计、仿真、PCB制作为全流程实践载体，学生作为投标方参与应标，教师基于AI开展辅助评阅，构建需求分析、设计开发、投标实施的完整实践链条。通过逆向设计教学活动，将信息辨识能力、自主学习能力和诚实守信品格的培养融入教学全过程，实现知识传授、能力培养与价值塑造的有机融合。教学实践表明，该模式能有效激发学生学习兴趣，在培养学生正确使用AI工具、提升解决复杂工程问题能力方面取得了良好效果，为AI时代工科实践教学改革提供了可借鉴的案例。

Abstract: In response to the current issues in digital electronics technology teaching, such as insufficient cultivation of students’ practical abilities and the lack of effective guidance in using artificial intelligence tools, this paper proposes a teaching reform plan based on the Outcome-Based Education concept. The plan introduces a simulated bidding mechanism and AI-assisted tools into the second classroom of digital electronics technology. Using the design, simulation, and PCB fabrication of basic digital logic circuits as the full-process practical platform, students participate as bidders in the bidding process, while teachers conduct AI-assisted evaluation. This approach builds a complete practical chain of needs analysis, design and development, and bid implementation. Through backward design of teaching activities, the cultivation of information discrimination ability, autonomous learning ability, and integrity is integrated throughout the entire teaching process, achieving an organic integration of knowledge impartation, ability cultivation, and value shaping. Teaching practice has shown that this model effectively stimulates students’ learning interest. It has achieved good results in guiding students to correctly use AI tools and enhancing their ability to solve complex engineering problems, providing a referable example for the reform of engineering practice teaching in the AI era.
