我以小组合作学习为主要手段,在学生的自主、合作、探究中,探索了用待定系数法求二次函数解析式的几种方法,学生兴趣很浓,效率很高。现在谈谈在实际操作中的几点体会。1.合理分配学习小组。我根据学生课上、课下的学习表现和自我约束能力等方面,先将本班三十人分成ABCDEF六个层面,每个层面均有五人,老师指定A层面的五位同学为组长,再由组长从同学的友情、有利于合作探究、互助学习、共同进步等方面出发,去BCDEF五个层面各选一名同学,来组建由六人构成的学习小组,明确每个组员的职责。这样 I take the group cooperative learning as the main method. In the autonomy, cooperation and exploration of students, I explored several methods to solve the quadratic function with undetermined coefficient method. The students are very interested and efficient. Let us now talk about some experiences in practice. 1. Reasonable distribution of learning groups. According to the students in class, class performance and self-restraint and other aspects of the first class of 30 people divided into ABCDEF six levels, each level has five people, the teacher designated A level five students as the leader , Then the leader from the classmates friendship, is conducive to cooperation and exploration, mutual aid learning, common progress and other aspects, to BCDEF five levels each choose a classmate, to form a six-member learning group, clear each member Responsibilities. such
