教学内容与学生学业负担形成的矛盾致使教师灵活运用教材的空间被严重压缩,学生在被动的学习状态下,运用机械记忆的学习方式,使得原本自成体系的数学内容被生硬地交割。学生的实际运用能力也就无从谈起,这也直接导致了教师之教与学生之学巨大落差的形成。如何在教学实践中,运用积极有效的策略,消弭这种落差呢?一、组建知识版块,在知识联系中消弭落差教与学之间落差的形成源于学生运用能力的缺失。而运用能力的缺失要么是由于学生知识的遗忘,要么是由于 The contradiction between the teaching content and the students ’academic burden leads to the severe compression of teachers’ use of teaching materials. Students use the mechanical memory learning method in the passive learning state to make the original self-contained mathematics content be delivered bluntly. Students can not use the practical ability to use, which also led directly to the teaching of teachers and students a huge gap between the formation of the school. How to eliminate this gap by applying positive and effective strategies in teaching practice? First, the formation of knowledge forum, the formation of the gap between education and learning in the knowledge link, stems from the lack of students’ ability to use. The lack of ability to use either because of the forgotten students knowledge, or because
