探索多媒体在"离散数学"教学中的应用

离散数学是计算机专业的专业基础课。通过这门课程的学习，可以培养学生的抽象思维和逻辑推理能力，并使他们掌握处理离散结构所必须的描述工具和方法。但是。由于这门课程具有概念多、理论性强、高度抽象等特点，使得在实际教学过程中出现了学生学习积极性不高．教学效果不理想的现象。而多媒体作为一种有效的辅助教学手段，集声音、图像、视频和文字等媒体为一体。能产生生动活泼的效果。将多媒体教学引入离散数学课堂，可以激发学生的学习兴趣，充分调动学生的学习积极性。本文结合笔者在教学过程中应用多媒体的实践，提出了在离散数学课程中实行多媒体教学的一些尝试，并讨论了一些需要完善和思考的问题。
