| This research is centered on “the development of critical thinking of college student based on the learning scaffoldingâ€,based on the related study,defining critical thinking and the core components,summarizing the critical thinking process and explicit feature,construct critical thinking cultivation model based on the learning scaffolding.Constantly revised through the teaching practice to improve the model,and verify the feasibility and validity of the model.The introduction part of this study provides an overview of the background,the research purposes and the significance,content,ideas and methods.In addition to the part of introduct ion,the paper has four parts.(1) The review of literature.This part of the study involves about the definition of critical thinking and components,analyse the existing cultivation strategies and methods,understand the application of learning scaffolding in the teaching practice.Adopting participatory learning and case teaching and combining with specific subject content for critical thinking cultivation,then finding out the problem in the the study of interaction research.(2) The construction of the development model of critical thinking of college student based on the learning scaffolding.Basing on the research of critical thinking from home and abroad,summarizing the critical thinking process and explicit feature,construct critical thinking development model with the feature of learning scaffolding.This model consists of three phases,it‘s finding out the problems(or opinions) phase,collecting and disposing information phase,solving the problem(or ideas argument) phase.the learning scaffolding include example of cases,tools and templates etc.(3) Teaching practice on the development of critical thinking and the results analysis.In this part,used the <Design and Implementation of Training Projects> as an example,design learning activities and learning scaffolding based on the development model,analyse the change of students‘ critical thinking skills and the effect of learning scaffolding through the three rounds teaching practices.In order to perfect developmentmodel,summarize the shortcoming of design,application and practice,put forward to modificate the project.(4) Conclusion.This part summarized the main research achievement and results,illuminated three innovation points,and analysed the shortcomings of this study,prospected the future research.This research construct critical thinking development model based on the learning scaffolding through the analysis and understanding of critical thinking.Used the idea of Design-Based Research to teaching practice and modify modle,then enhance the students’ critical thinking.The research indicate that the development model to promote the collage student’ critical thinking are effective and feasible. |
