| Collaborative Problem Solving,as one of the 21st century skills,is an important way to promote individual cognitive development and social development,and an important dimension of talent training.The core research problem of this thesis is how to cultivate the ability of Collaborative Problem Solving.It can be further divided into two sub-problems.First,what is Collaborative Problem Solving?What are its concept connotation,content frame,influencing factors and theoretical basis?Second,how to teach Collaborative Problem Solving skills?What are the teaching strategies?How are these strategies used in the classroom?How effective is the implementation?How to get the strategies improved?Based on the systematic review and analysis of the international literature on Collaborative Problem Solving,this thesis defines Collaborative Problem Solving as "a process in which team members transform the current state into the goal state through a series of interaction to achieve a goal that cannot be achieved individually".The cultivation of Collaborative Problem Solving ability mainly includes the following three strategies:situational strategies,discourse strategies and cognitive strategies.Situational strategies are mainly used to create Collaborative Problem Solving situation,so as to cultivate learners’ ability to solve practical problems.Discourse strategies are mainly committed to using different types of discourse to promote the development of collaboration,so as to promote collaboration and improve learners’ collaboration skills.Cognitive strategies mainly use cognitive tools to lead the cooperators’ cognitive activities,so as to cultivate the learners’ cognitive skills and develop their higher-order thinking ability.Finally,this study uses the strategies to analyze three course videos,and explores how situational strategies,discourse strategies and cognitive strategies are implemented in classroom teaching.Through the analysis of the video,it is found that in the use of situational strategies,team interdependence still needs to be further enhanced,and the sense of team division of labor also needs to be further cultivated.In the use of discourse strategies,students should be encouraged and guided to express logically and their awareness of equal participation should be enhanced.In the use of cognitive strategyies the cognitive path shall be further enriched;the awareness and ability related to task management should be improved. |
