“数学味”是数学课堂的永恒追求。现在有的小学数学课堂被包装成图文并茂、有声有色的精美课件,虽然满足了学生的耳目享受,却未必能调动他们学习的积极性,有时还会分散他们的注意力,淡化数学思考。因此,作为辅助手段的多媒体课件,当以实用为标准,而不是越精美越好。我们要把多媒体与数学课堂相整合,突出教学重点,突破传统教学无法理解的教学难点,要求展示事物变化的过程,刺激学生探求知识的欲望,引发学生主动、积极、创新的思维,从而促进学生主动、和谐地发展。 “Mathematical taste ” is the eternal pursuit of mathematics classroom. Nowadays, some primary school math classrooms are packed with pictures and textures. The beautiful audio-visual courseware, although satisfying the students’ appetites, may not be able to arouse their enthusiasm for learning and sometimes distract their attention and dilute their thinking in mathematics. Therefore, as an auxiliary means of multimedia courseware, when practical as the standard, not the more beautiful the better. We should integrate the multimedia and mathematics classrooms, highlight the teaching points, break through the teaching difficulties that traditional teaching can not understand, request the process of changing things, stimulate students’ desire to seek knowledge, and lead students to take the initiative, positive and innovative thinking to promote students Active and harmonious development.
