生成与预设是教学中的一对矛盾统一体。课前预设是传统教学的一个典型特征,而动态生成是课改中的一个重要形式。随着课程改革的不断推进,教师们一味地追求动态生成的课堂,而课前材料的精心预设却被逐渐忽视。笔者认为,精彩的生成得益于精心的预设,只有课前精心选择预设材料,努力使预设材料生活化、活动化,努力使预设材料有利于学生数学思维的发展,继而在课堂中活用预设材料,才能呈现扎实、有效的数学课堂教学。下面就数学课堂预设材料的选择策略谈几点思考,供大家参考。一、预设材料的选择应有利于数学知识生活化不论是课改的昨天、今天,还是明天,都非常强调数学与
Generation and presupposition are a pair of contradictory unity in teaching. Pre-setting is a typical feature of traditional teaching, and dynamic generation is an important form of curriculum reform. With the continuous reform of the curriculum, teachers blindly pursue the dynamically generated classroom, while the pre-school material carefully preset has been gradually neglected. The author believes that the splendid generation is due to meticulous presupposition, only the pre-class material carefully selected, and strive to make the default material life, activities, and strive to make the default material is conducive to the development of mathematical thinking, and then in the classroom In the use of pre-set materials, in order to show a solid, effective math classroom teaching. The following mathematics classroom preset material selection strategy talk a few ponders, for your reference. First, the choice of the default material should be conducive to the life of mathematical knowledge Whether it is yesterday, today, or tomorrow, all emphasize mathematics and
