OBE理念下项目式教学模式的优化构建——以中职《图形图像处理》课程为例

Optimization and Construction of Project-Based Teaching Model under the OBE Concept—A Case Study of the “Graphics and Image Processing” Course in Secondary Vocational Education

摘要: 本文针对中职《图形图像处理》课程存在的教学目标与岗位能力脱节、项目任务真实性不足、评价方式单一等现实问题，以成果导向教育(OBE)理念为引领，融合项目式教学(PBL)的实践特性，构建了一套适用于该课程的教学模式。研究首先通过理论梳理，阐明OBE与PBL在目标导向、教学设计及评价机制上的内在契合性；继而遵循反向设计、持续改进原则，提出了包含“目标驱动–能力进阶–多元评价–持续改进”四个核心环节的总体框架，并按照课前、课中、课后三阶段对其实施流程进行了详细设计。该模式强调以岗位能力模型为起点，通过真实项目任务推动学生能力进阶，借助多元化评价促进教学闭环改进，为中职数字媒体技术专业课程教学改革提供了系统的理论框架与可操作的实施路径，对推动职业教育课堂革命、深化产教融合具有积极的理论价值。

Abstract: This article addresses the practical issues in the teaching of the “Graphics and Image Processing” course in vocational schools, such as the disconnection between teaching objectives and job competencies, the lack of authenticity in project tasks, and the single evaluation method. Guided by the concept of Outcome-Based Education (OBE) and incorporating the practical characteristics of Project-Based Learning (PBL), a teaching model suitable for this course is constructed. The research first clarifies the inherent compatibility of OBE and PBL in terms of goal orientation, instructional design, and evaluation mechanisms through theoretical analysis. Then, following the principles of reverse design and continuous improvement, an overall framework consisting of four core links, namely “goal-driven, ability progression, diversified evaluation, and continuous improvement”, is proposed. The implementation process is detailedly designed according to three stages: before class, during class, and after class. This model emphasizes starting with the job competency model, promoting student ability progression through real project tasks, and facilitating closed-loop teaching improvement through diversified evaluation. It provides a systematic theoretical framework and an operable implementation path for the teaching reform of digital media technology courses in vocational schools, and has positive theoretical value in promoting classroom revolution in vocational education and deepening industry-education integration.
