Abstract

This study deeply integrates the concept of Outcome-Based Education (OBE) with Student Research Training (SRT) projects, systematically reconstructs the teaching system of "DSP (Digital Signal Processor) Technology and Its Applications", which is a core course for electronic information majors. While OBE and Project-based Learning (PBL) have been widely explored, a deep synergy mechanism that systematically maps SRT project tasks directly onto hierarchical OBE learning outcomes, supported by a data-driven intelligent evaluation feedback loop, was notably lacking in previous reforms. Guided by industrial demands and engineering education accreditation standards, the research reversely designs and refines three-level OBE learning objectives, decomposes SRT tasks, and organically integrates them into the course's theoretical teaching and practical links, and implements an intelligent multi-source evaluation system. The results show that after the reform, the average course score increased significantly by 10.37 points, and the excellent rate rose by 19 percentage points. Three innovative mechanisms were developed: a dynamic content adaptation mechanism, a trinity collaborative teaching model, and a learning analytics-driven evaluation system. To address challenges such as project integration depth and teacher workload, optimization strategies, including a hierarchical project library and a refined innovation evaluation model, are proposed. This study provides a replicable practical paradigm and theoretical reference for in-depth reform of core courses in electronic information majors in the background of engineering education accreditation.
