1问题的提出建构主义提出:数学学习是一个记忆、理解、应用、建构的过程,即学生通过记忆新学知识并与原有的知识储备建立联系、从而理解新学知识,并运用解决问题,最终实现新的知识建构.要实现这一建构必须依托数学问题即数学作业.作业是教学环节的一个重要组成部分,更是学生进一步消化和巩固课堂所学知识,掌握相应技能,培养学习能力的有效措施.然而,没有目的的作业非但不会提高学生的成绩和学习热情,反而会促成他们对作业的消极态度.当前,农村初中由于受升学的压力、家长的不重视、教师观念未彻底转变等多方面因素影响,数学作业量多质低,有效性不高.在这样的背景下,需要我们去
1 Propositional Question Constructivism proposes that mathematics learning is a process of memory, comprehension, application and construction. That is, students can understand the new knowledge through the memory of new learning knowledge and their original knowledge reserve, and use the methods of solving problems, And finally realize the new knowledge construction.To achieve this construction must rely on the mathematical problem that is math homework is an important part of the teaching process is more students to further digest and consolidate the knowledge learned in the classroom to master the appropriate skills to develop learning ability However, the purpose of homework not only will not improve students’ performance and enthusiasm for learning, but will lead to their negative attitude towards homework.Currently, rural junior high school due to the pressure of further studies, parents do not attach importance to the concept of teachers is not completely changed And many other factors, the quality of math homework is low and the effectiveness is not high. In this context, we need to go
