基于OBE理念的化工类专业制图课程教学改革探索

Teaching Reform Exploration of Chemical Engineering Drawing Course for Chemical Engineering Majors Based on OBE Concept

摘要: 化工制图是化工类专业培养学生工程图样阅读与绘制能力的核心课程，对后续课程学习与工程实践能力养成具有重要支撑作用。针对当前课程普遍存在的内容偏向机械制图而忽视化工特色、课时压缩导致实践环节薄弱、教学方法单一、考核偏重知识记忆而忽视能力评价等问题，本文以成果导向教育(OBE)理念为指导，从课程内容、教学方法、资源建设与考核评价四个维度提出了系统的改革路径：重构以制图基础、化工设备与化工工艺三大模块为核心的内容体系，将CAD教学贯穿全过程；引入任务驱动教学法，围绕真实绘图任务组织教学；建设微课视频、三维模型库与在线平台相结合的立体化教学资源，开展线上线下混合式教学；建立过程性与终结性相结合、笔试与机试相补充的多元化考核评价体系。

Abstract: Chemical Engineering Drawing is a core course for chemical engineering majors to cultivate students’ ability to read and produce engineering drawings, playing a significant supporting role in subsequent course learning and the development of engineering practice capabilities. In response to the prevalent problems in the current course, including content biased toward mechanical drawing while neglecting chemical engineering characteristics, reduced class hours leading to weak practical training, monotonous teaching methods, and assessment emphasizing knowledge recall over competence evaluation, this paper, guided by the Outcome-Based Education (OBE) concept, proposes systematic reform pathways from four dimensions: course content, teaching methods, resource development, and assessment and evaluation. The reform pathways include restructuring the content system around three core modules—fundamental drawing, chemical equipment, and chemical process—with CAD instruction integrated throughout; introducing a task-driven teaching method organized around authentic drawing assignments; developing multi-dimensional teaching resources combining micro-lecture videos, 3D model libraries, and online platforms to implement blended online-offline teaching; and establishing a diversified assessment system that combines process-oriented and summative evaluation, as well as written tests and computer-based examinations.
