Abstract: As a core course for majors such as Materials Science and Engineering and Mechanical Engineering, “Principles and Technologies of Metal Heat Treatment” is characterized by highly abstract theories and demanding practical requirements. To address issues in traditional teaching-including theoretical abstraction, limited practical conditions, tight schedules, and insufficient interaction, this study has systematically constructed and implemented a deeply integrated online-offline blended teaching model based on the Superstar Learning Platform. This model restructures the entire teaching process into “pre-class knowledge transfer, in-class knowledge internalization and competency enhancement, and post-class knowledge consolidation and extension.” Centered on core heat treatment theories and key processes, it integrates and develops a series of high-quality digital teaching resources while designing and implementing diverse interactive activities that fuse online and offline elements. The reform aims to enhance students' autonomous learning, classroom engagement, depth of understanding of abstract theories (such as solid-state phase transformations, CCT and TTT curve analysis), and practical problem-solving abilities for complex engineering issues (including heat treatment process formulation, optimization, and failure analysis). It offers a valuable practical pathway for pedagogical reform in core engineering courses.
