课堂是学习的主阵地,课堂生活是学生最重要的学习生活,学生的课堂生活质量不仅决定了学生学习的质量,也影响着以学习为主要任务的学生的生活质量。反观当前的课堂,都不同程度地存在着高耗低效的现象,并导致了学生学习兴趣丧失、学业负担过重、学业质量低下。因此,在倡导生态理念的今天,我们理应把关注的目光投向学生的课堂生活,分析课堂高耗低效的原因,寻求解决问题的对策,让学生学有“发展”的数学。一、研读教材:学有“营养”的数学 Classroom is the main position of learning. Classroom life is the most important learning life for students. The quality of class life of students not only determines the quality of students’ learning, but also affects the quality of life of students whose main task is to learn. On the contrary, the present classroom has the phenomenon of high consumption and inefficiency in varying degrees, which leads to the loss of students’ interest in learning, the heavy academic burden and the low academic quality. Therefore, in advocating the concept of ecology, we should turn our attention to the classroom life of students, analyze the causes of high and inefficient classrooms, find solutions to problems, and allow students to learn mathematics of “development ”. First, study textbooks: learn to have “nutrition ” mathematics
