水力学课程教学手段探讨

介绍了教学手段的内涵，分析了实物、模型、板书、挂图、投影胶片、纸介质讲义、多媒体等教学常用知识载体的优缺点及其选用原则；针对有颇多争议的多媒体教学问题，以水力学及工程流体力学教学为例，概述笔者在备课、多媒体课件制作以及课堂使用过程中的体会，包括知识点分解、表达形式再加工、课件制作技术、课件播放、教与学互动、多媒体与板书的配合、口头与肢体语言运用等内容；讨论了多媒体技术为现代教育带来的机遇与挑战。

Rational use of teaching methods in the course of hydraulics

Advantages and disadvantages of different media, including practical objects, models, blackboard writing, wall maps, film projection, printed conspectus, and multi-media tools, as well as utilization principles were analyzed. Due to the disputation of multi-media utilization in teaching process, we shared our experience in preparing and teaching by using different media in hydraulics course and engineering fluid mechanics course, including multi-media technologies. Detailed processes were introduced, such as decomposition of key point concepts, expression and reconstruction of the knowledge, presentation preparation, the playing pace of presentation, intercommunication with students, collaborative application of blackboard writing and compute presentation, and talking emphasized by body language. As a conclusion, opportunities and challenges brought by multi-media technologies to education were discussed.
