【摘要】：中等职业学校《化工分析》课程既是化工技术类专业的基础性课程，又是核心课程。课程目的是培养学生掌握化学检验工作的基础知识、操作技能、管理知识和标准化知识。课程特点是理论性与实践性强，教学难点是学生对理论的消化慢，技能掌握不扎实。产生这种教育问题的原因很多，其中既有学生底子薄，理解能力差、消化过程长等客观因素，也有教学设计不合理，教学手段单一、缺乏针对性等客观因素。因此，在充分尊重客观因素现实存在的基础上如何利用现代化教学手段，改进中等职业学校《化工分析》课程的教学模式，培养学生的学习兴趣，提升学生的认知能力，提高学生的实践技能，实现课程的教学效果，便成为《化工分析》课程教师的研究方向。本研究以中等职业院校《化工分析》课程为研究对象，在分析国内外多媒体教学发展与现状的基础上，阐述了中等职业院校《化工分析》教学应用多媒体教育技术的必要性，探讨了多媒体课件的设计原则和设计思路，并结合具体教学案例，提出了《化工分析》课程实施多媒体辅助教学的教学策略，同时，总结了多媒体教学的经验与存在的问题，为进一步完善教学手段，优化多媒体技术在《化工分析》课程中的应用奠定基础。结果表明，通过巧妙而恰当的设计、开发、运用多媒体教学，使之与其他教学手段有机结合，优化了教学设计。通过改革教学方法，加强了师生交流，实现了人机互动，，改变了教与学的关系，提高了学生的学习兴趣和学习主动性，取得了比较理想的教学效果。
[Abstract]:The course of chemical analysis in secondary vocational school is not only the basic course of chemical technology specialty, but also the core course. The purpose of the course is to train students to master the basic knowledge and operation skills of chemical inspection. Management knowledge and standardized knowledge. The curriculum is characterized by strong theory and practice, teaching difficulties are the students' slow digestion of theory, skill grasp is not solid, there are many reasons for this kind of educational problems. There are not only some objective factors, such as students' weak foundation, poor understanding ability, long digestion process, but also some other objective factors, such as unreasonable teaching design, single teaching means, lack of pertinence and so on. On the basis of fully respecting the reality of objective factors, how to improve the teaching mode of chemical analysis course in secondary vocational schools and cultivate students' interest in learning by using modern teaching methods. Improving students' cognitive ability, improving students' practical skills and realizing the teaching effect of the course become the research direction of "Chemical Analysis" course teachers. Based on the analysis of the development and present situation of multimedia teaching at home and abroad, the course of chemical analysis in secondary vocational colleges and universities is taken as the research object. This paper expounds the necessity of the application of multimedia education technology in the teaching of Chemical Engineering Analysis in secondary vocational colleges and probes into the design principles and ideas of multimedia courseware, and combines with concrete teaching cases. This paper puts forward the teaching strategy of implementing multimedia aided teaching in the course of Chemical Engineering Analysis, and summarizes the experience and existing problems of multimedia teaching in order to further perfect the teaching method. Optimizing the application of multimedia technology in the course of Chemical Engineering Analysis lays the foundation. The result shows that the multimedia teaching is organically combined with other teaching means through ingenious and appropriate design, development and application of multimedia teaching. Through the reform of teaching methods, the communication between teachers and students has been strengthened, man-machine interaction has been realized, the relationship between teaching and learning has been changed, and students' interest and initiative in learning have been improved. A more ideal teaching effect has been achieved.
