在传统课堂上,由于教具、方法和手段等教学环境的限制,数学教学中的一些抽象思维难以生动有效地传达给学生,课堂往往缺乏协作互动,学生主体地位不能充分体现,集体智慧不能充分共享。这些都不利于提高教学效果,而且限制了学生动手能力、合作能力和创新精神的培养。在有了交互式电子白板之后,我们适时恰当地选用交互式电子白板来辅助教学,以逼真、生动的画面来创造教学的丰富情景,使抽象的数学内容形象化、清晰化,使数学知识由静态的灌输变为图文声像并茂的动态传播,可以大大激发学生积极主动的学习
In the traditional classroom, some abstract thinking in mathematics teaching can not be vividly and effectively communicated to students due to the limitations of teaching aids, methods and means of teaching environment. The classroom often lacks collaboration and interaction, the students’ subjective status can not be fully reflected and the collective wisdom can not be fully shared . These are not conducive to improving teaching effectiveness, but also limits the students ability to work together to develop cooperation and innovative spirit. With the interactive whiteboard, we timely and appropriate selection of interactive whiteboards to assist teaching, with realistic and vivid images to create rich teaching scenarios, the abstract mathematical content visualization, clarity, so that mathematical knowledge from Static instillation into the dynamic image and audio broadcast, can greatly stimulate students to actively learn
