助学单,是“助学法”中用以引导学生在课堂教学前进行个体独立探索学习的材料,它不仅能让学生做好学习的心理准备,更重要的是让学生在自主探究过程中,获得重要的数学知识以及基本的数学思考方法和必要的应用技能。而在助学单的研制上,不仅仅要关注知识的学习和技能的训练,更应从数学课程总体目标的达成和学生发展上考虑,使得助学单不仅仅为教师的“教”服务,更重要的是为学生更好地“学”服务。一、从功能上分析,助学单要能助推学生的探究式学习 Aid to study is a kind of material that can be used to guide students to independently explore and study before the class teaching. It can not only make the students prepare mentally, but more importantly, The process, access to important mathematical knowledge and basic mathematical thinking and the necessary application skills. However, in the development of student’s aid list, we should not only pay attention to the study of knowledge and the training of skills, but also take into account the achievement of the overall goal of the mathematics curriculum and the development of students so that the student-aid service is not only for teachers’ teaching , More importantly, for students to better “learning ” service. First, from the functional analysis, to help students learn a single inquiry-based learning
