“指导自学法”即在教师指导下,充分发挥学生的主体作用(课堂上以学生为主,以自学为主),通过师生双边活动将课堂信息的交流由原来老师→学生的单向交流变为学生 老师 学生的立体交流.使学生掌握数学知识并形成数学能力.根据加里培林智力技能按阶段训练的理论,我们把整个实验分为两个阶段:训练智力动作和独立自学. Under the guidance of teachers, “Guiding Self-study Act” gives full play to the main role of students (mainly students in class and self-learning), and through the bilateral activities of teachers and students, the exchange of class information from one teacher to the student one-way communication To become a three-dimensional exchange of student teachers and students to enable students to master mathematical knowledge and the formation of mathematical ability.According to Gary Perlin intellectual skills in stages of training theory, we divided the entire experiment into two stages: training intellectual action and independent self-study.
