Inquiry Into The Teaching Design And Practice Of Junior Middle School Mathematics Cooperative Learning Oriented To Problem Solving

With the gradual progress of a new round of curriculum reform,"Independent inquiry,cooperation and exchange" and other teaching concepts are continuing to deepen in junior high school teaching.With this idea,group cooperative learning came into being,nowadays,It has developed into one of the most popular mathematics teaching methods at present,which can help students gradually form creative thinking,make students become the subject of teaching activities,and also cultivate the sense and ability of cooperation among students.Problem solving has become the main direction of teaching in mathematics classroom,it is very important to improve students' problem-solving ability in mathematics teaching.In view of various prominent problems found in the practice of mathematics teaching,this paper tries to solve the problem as the goal oriented,to optimize the original classroom teaching,propose a new instructional design for cooperative learning in mathematics classroom.This paper is divided into six chapters.The first chapter elaborates the research background,content,ideas and related researches on problem solving and cooperative learning at home and abroad;the second chapter briefly defines the concepts of cooperative learning and problem solving,and discusses the relevant theories supporting this research;the third chapter puts forward the instructional design of problem-solving cooperative learning,and gives the corresponding strategies of cooperative learning from the perspectives of teachers and students respectively;the fourth chapter carries on the teaching design to the ninth grade "the image and the property of quadratic function" in the PEP textbook,as a specific cooperative learning design case;in the fifth chapter,the subject is further discussed by experimental research method and the experimental results are obtained;the sixth chapter is the summary of the thesis and the prospect of research.The research results show that the teaching design and micro-strategy of cooperative learning proposed in this paper can improve the cooperative behavior of group members in practice,make intra-group cooperation more standardized and efficient,and effectively enhance the mutual cooperation ability and problem solving level among students.At the same time,it can also make students' learning attitude change positively to a certain extent,indicating that problem-solving cooperative learning design is effective.
