| With the continuous development of the new curriculum reform,more and more teachers pay attention to the "Student-centered"classroom,and group cooperative learning is widely used in classroom teaching because it conforms to the idea of the new curriculum reform,but in the actual teaching process,the cooperation is mostly in the form,the teaching effect is not ideal,the student study enthusiasm and interest are also greatly affected.However,problem continuum teaching has its unique advantages in stimulating students’learning interest and arousing their enthusiasm.Therefore,this paper integrates problem continuum into group cooperation,and constructs a group cooperation model based on problem continuum,in the process of cooperative discussion,we should train students’problem-solving ability and cooperative communication ability,bring students’subjectivity into play,and promote students’all-round development.First of all,through the method of Literature Research,this paper analyzes and sorts out the related research of Problem Continuum and Group Cooperation,and discusses the important significance of problem-based teaching and group cooperation in junior middle school chemistry classroom teaching,it defines the core concepts of problem continuum and group cooperative learning,and expounds the learning theories of Constructivism,Theory of multiple intelligences and humanism.Secondly,through the design of questionnaires and interviews,the author investigates and analyzes the current situation of the application of problem continuum and group cooperation in chemistry teaching in grade three,and on this basis,constructs the framework of teaching practice model,the teaching flow of Group Cooperation Model of problem continuum is designed,and the principles and ideas of problem design are put forward.Three teaching contents of "Air","Oxygen","Molecule and atom" were selected to carry out the practice.Finally,through the questionnaire,interviews,test results to test the effectiveness of teaching practice.The results show that the model of group cooperation based on problem continuum can not only enliven the classroom teaching atmosphere,arouse students’learning enthusiasm and stimulate students’learning interest,in addition,it can improve students’problem-solving ability and cooperative communication ability at the same time.Therefore,the group cooperation model based on problem continuum has certain research value. |
