Design And Practice Of Teaching Mode For The Cultivation Of Critical Thinking Of Junior High School Students Under The Concept Of Maker Education

With the advent of the 21 st century,more and more information floods into people's lives.It is difficult to distinguish between true and false information.Critical thinking,as one of the core qualities,plays an important role in people's lives.However,the development of critical thinking of middle school students in our country is not optimistic,and there are many problems in the cultivation of critical thinking,and further improvement is urgently needed.Through the analysis of a large number of documents,it is found that the concept of maker education is suitable for the cultivation of critical thinking,and is especially suitable for solving the problem of lack of communication and cooperation and practical reflection in the cultivation of critical thinking.Therefore,this research aims to think about how to guide the concept of maker education.Cultivate the critical thinking of junior high school students and try to construct a teaching model for critical thinking training.This research is based on Hegel's reflection theory,Dewey's theory of learning by doing,and Bloom's theory of goal classification in the cognitive domain.After analyzing specific teaching goals,teaching methods,and teaching evaluation,it is constructed for the purpose of cultivating students' critical thinking.Teaching mode.The model is divided into four important stages,namely the input stage,project exploration,independent creation,and summary stage.These four stages focus on the four steps of questioning,analyzing,generating,and reflecting on critical thinking.In each stage All of these four steps are repeated and strengthened,but the training focus of each stage is different.In the specific implementation,51 students in a class of the first grade of a middle school in N city were selected as the research objects,and a 13-week teaching experiment was carried out.The first round of teaching experiments lasts for 7 weeks.The project is based on the theme of "Little Campus Tour Guide",which is close to the reality of student life on campus.After the project is completed,it combines student critical thinking scale scores and classroom observations to reflect on the teaching model as a whole Modified,and then put into the second round of teaching practice.The second round of teaching experiments lasts for 6 weeks.The project is based on the theme of "Environmental Protection Guards".The main function is to realize intelligent waste classification,combine practical experience to complete the project,measure and analyze the changes in students' critical thinking after the project is completed,and combine classroom observations Fine-tune the teaching mode,and finally get a scientific and effective teaching mode.The final experimental results show that this teaching mode can effectively improve students' critical thinking ability.
