• Abstract: In the context of Outcome-Based Education (OBE), addressing the pain points such as theoretical abstraction, low student participation, and singular assessment methods in foundational courses for electronic and information engineering majors, this paper takes the “Signals and Systems” and “Digital Signal Processing” courses as research objects and independently develops a visual experimental platform based on MATLAB App Designer. Combining constructivist learning theory, a blended teaching model of “pre-class rehearsal - in-class exploration - post-class extension” is reconstructed, and a multi-dimensional process evaluation system is established. A complete teaching practice was carried out with 90 undergraduates from two classes of the 2024 cohort in electronic and information engineering majors as empirical objects. Empirical data show that this reform plan effectively breaks the barriers between theory and practice, significantly improving the achievement degree of course objectives and students’ classroom participation. This model holds high promotion value for the teaching reform of similar foundational professional courses. 在工程教育专业认证（OBE）背景下，针对电子信息类专业基础课程中存在的理论抽象、学生参与度低及考核方式单一等痛点，本文以“信号与系统”及“数字信号处理”课程为研究对象，自主开发了基于MATLABAppDesigner的可视化实验平台。结合建构主义学习理论，重构了“课前预演—课中探究—课后拓展”的混合式教学模式，并建立了多维度的过程性评价体系。以2024级电子信息类两个班级共90名本科生为实证对象，开展了完整的教学实践。实证数据表明，该改革方案有效突破了理论与实践的壁垒，显著提升了课程目标达成度与学生的课堂参与度。该模式对同类专业基础课程的教学改革具有较高的推广价值。
