学习材料作为学生探索活动的重要载体,影响着学生探索活动的有效性。从数学教学“引导性材料”呈现的需要出发,结合一次同课异构课堂教学比赛探讨如何选择有利于学生思维投入的学习材料,怎样正确使用学习材料,充分挖掘学习材料的价值,从而促进学生在学习过程中能进行有效探索,使学生获得充分发展。 Learning materials as an important carrier of student exploration activities, affecting the effectiveness of student exploration activities. Based on the need of presentation of “teaching material” in mathematics teaching and combining with a class competition in heterogeneous classroom teaching, this article discusses how to choose learning materials that are good for students’ thinking, how to use learning materials correctly and fully exploit the value of learning materials Promote students in the learning process can be effectively explored to enable students to fully develop.
