The Design And Application Research Of Problem-solving Teaching Model Oriented To Computational Thinking

With the continuous development of information technology,the way people analyze and deal with problems is constantly changing.In recent years,the concept of computational thinking has continuously poured into people's field of vision,and has also received widespread attention from the education community.The newly revised high school information technology curriculum standards also regard computational thinking as one of the four core literacy of information technology.By reading the literature,more and more scholars associate computational thinking with the discipline of information technology.The programming module in the information technology discipline is seen as the most important part of improving students' computational thinking.In the domestic use of programming modules to enhance students'computational thinking ability,there is no complete teaching system at both the theoretical level and the practical level.They are all in the primary exploration stage,how to improve students' computational thinking ability in the high school C language programming course.It is the starting point and goal of this research.Based on the learning theories of constructivism,cognition,and cooperation,this study analyzes the existing programming teaching model and excellent teaching cases at home and abroad,and builds a problem-solving teaching model.According to the teaching model,the teaching design is carried out.In the first year of the information technology course,two parallel classes were selected for teaching practice.After the practice,the teaching results of the model were verified through questionnaires and student interviews,which provided the teachers with the teaching in the development of students' computational thinking.reference.This research is roughly divided into five parts:study literature,build teaching models,teaching practice,test teaching effects,summary and outlook.In this part of the research literature,the author searches the "programming teaching mode" and "computational thinking" as keywords,and conducts a literature review of computational thinking concepts,computational thinking teaching,and computational thinking program teaching,and discovers the construction of different scholars.The teaching mode is related to solving a specific problem.Therefore,in the pattern construction stage,the author tries to construct a problem-solving teaching mode.In the part of the construction mode,the main part is to solve the existing problem and solve the teaching mode and excellent teaching at home and abroad.Case,analyzing the teaching status quo of program design,under the guidance of constructivism,cognitiveism and other theories,combined with the specific teaching situation to construct the corresponding model,then formalize the model with mathematical formula,and design the teaching according to the model.In the teaching practice part,the author takes the first grade of high school as the research object,and uses C language programming as the teaching content to carry out teaching practice.In the teaching effect part,the author adopts the quasi-experimental research method,analyzes the students' computational thinking level through specific questionnaire survey and test score analysis,and then verifies the effectiveness of the problem-solving teaching mode.In the summary of the prospects,the author summarizes the problems in the teaching process based on the interviews,questionnaire results and test scores of the students,and gives corresponding strategies according to the problems.The problem-solving teaching model for computational thinking training focuses on improving students' computational thinking,and integrating computational thinking into the programming curriculum can deepen the understanding of more thinking learners and teachers on computational thinking.Through the combination of quantification and qualitative,this study draws the following conclusions:The problem-solving teaching model constructed in this paper can improve students' ability to analyze problems and solve problems,and solve the problem of problem-solving teaching mode than traditional teaching.The teaching of the model is better.
