2004年4月24日在我校举办了“华县高中语、数、英、物、化五科多媒体教学公开课”,我听了华县铁中数学教师姜俭俭老师的“三垂线定理及其逆定理”这节多媒体教学公开课,下面谈一谈我对多媒体在教学中应用的认识。一、多媒体教学有效地培养了学生的数学形象思维多媒体作为现代化的技术用来辅助教学,有传统教学无法比拟的优越性,它能提供丰富的形象素材,构筑起表象与本质的桥梁,促进学生充分理解高度抽象的数学知识的实质,从而有效地培养了学生的数学形象思维。
On April 24th, 2004, we organized the “Multimedia Teaching Open Classes for High Schools, Counties, English, Arts, and Chemistry” in Hua County, and I listened to the “Three perpendiculars theorem and the teacher of Jiang Ti’s mathematics teacher Jiang Yan”. The inverse theorem of this section is the multimedia teaching open class. Now let’s talk about my understanding of the application of multimedia in teaching. First, multimedia teaching has effectively cultivated students’ mathematical thinking. Multimedia is used as a modern technology to assist teaching. It has superiority that cannot be matched by traditional teaching. It can provide rich image materials, build a bridge between appearance and essence, and promote students. Fully understand the essence of highly abstract mathematics knowledge, so as to effectively train students’ mathematical thinking.
