数学课堂教学中微视频导入存在的问题和优化路径

The Problems and Optimization Paths in Micro Video Import of Mathematics ClassroomTeaching

基于生活情境创设的微视频应用于数学课堂导入,具有针对性、导向性和趣味性,能够声形并茂中激发课堂活力。但当前课堂教学中普遍存在着导入形式化严重、内容单一,微视频内容简单粗糙,缺乏与新的授课内容密切联系,微视频直接替代了教师讲解等问题。提高教学质效,激发学生解决问题的求知欲和主动性,教师要善用微视频导入,以问题为导向,在图像声音多重感官刺激下引导学生掌握新知,训练学生用数学方法解决问题的能力。同时,辅助其他教学方法,做足课堂导入前奏,做好课前教学评估,方能起到事半功倍的效果。

The application of micro videos created based on life situations in mathematics classrooms is targeted,oriented,and interest-ing,and it can stimulate classroom vitality through a combination of sound and form.However,there are common problems in current classroomteaching,such as severe formalization of introduction,single content,simple and rough content of micro videos,lack of close connection with newteaching content,and direct substitution of teacher explanations by micro videos.To improve teaching quality and efficiency,stimulate students’thirst for knowledge and initiative in problem-solving,teachers should make good use of micro video im-ports,guide students to master newknowledge under multiple sensory stimuli of images and sounds,and train students’ability to solve problems using mathematical methods.At the same time,teachers should assist other teaching methods,make a thorough introduction to the classroom,and conduct evaluations before class so as to achieve twice the result with half the effort.
