Research On The Design And Application Of Blended Teaching Activities To Promote The Development Of Critical Thinking

With the rapid development of information technology and the deepening of education informatization,the competition for global talents is becoming increasingly fierce.Cultivating future talents with critical thinking and innovative ability is the focus of today's education reform.China clearly puts forward the scientific spirit as the core quality in the requirements for the development of students' core quality,and its rational thinking and critical questioning are the embodiment of paying attention to the cultivation of students' critical thinking.As an interdisciplinary subject,information technology has certain creativity and openness,which can provide students with more opportunities to question and think.High school information technology courses mostly adopt the traditional teaching method of demonstration / practice.How to innovate the teaching concept,optimize teaching by changing the teaching method and teaching mode,and improve students' innovative thinking and practical ability have become the problems that need to be solved in the current curriculum reform.In order to explore the new path of the integration of critical thinking ability training and hybrid teaching,this study combines the goal of the new curriculum reform in senior high school,consults the relevant literature at home and abroad,analyzes the application status of critical thinking elements and hybrid teaching mode in the field of education at home and abroad,defines the concept of critical thinking and hybrid teaching,and integrates them in accordance with constructivism theory,humanistic learning theory Guided by discovery learning theory.On the basis of investigation,based on the information technology curriculum of senior high school,combined with the analysis of information technology curriculum and teaching materials,teaching environment,teaching resources and learners,this thesis designs a mixed teaching activity process to promote critical thinking,and designs cases for specific teaching contents on the basis of this process.Taking the students of an ordinary high school in Dalian as the research object,a one semester teaching comparison practice was carried out.The diversified evaluation was carried out through classroom observation,questionnaire survey and interview,and the experimental results were analyzed scientifically around critical thinking.The practice shows that the practice of mixed teaching activities in high school information technology curriculum can promote the development of students' critical thinking.Through the comparative analysis of one semester's mixed teaching practice,students' critical thinking has a good performance in seeking truth,open thinking,analytical ability,systematic ability,self-confidence,thirst for knowledge and cognitive maturity,among which the two dimensions of seeking truth and cognitive maturity have been significantly improved.
