Research On The Construction And Application Of Blended Learning Model Based On The Cultivation Of Computational Thinking

In recent years,the policies in the field of educational informatization have been issued intensively,and the educational informatization in China has developed greatly.With the continuous progress of electronic equipment,mobile network,digital campus and other educational information environment,the advantages of educational information are more prominent.On the other hand,the state attaches great importance to vocational education,and puts vocational education in a more prominent position in educational reform and innovation and economic and social development,so as to provide high-quality human resources support for promoting economic and social development and improving national competitiveness.Secondary vocational education cultivates high-quality and applied functional talents in the front line of social labor positions,such as production,management and service.The social orientation and vocational education function of the training direction inherently determine that the training of vocational talents should pay more attention to the vocational quality of students.Vocational quality education is the main purpose of vocational education,and computing thinking is the professional thinking of computer practitioners Dimension,for noncomputer professionals,the application of computational thinking can greatly improve the quality and efficiency of work.According to the actual situation and needs of secondary vocational schools,this study constructs a hybrid learning model suitable for secondary vocational schools and carries out practical application.First of all,the researcher discusses the research background of this paper,through consulting literature,expounds the research status of hybrid learning and computing thinking,and then introduces the research significance,research methods and research ideas of this study.Secondly,it introduces the concept of blended learning and computational thinking,the constructivism learning theory,the OBE learning output theory and the thinking classroom teaching theory.Then,through the study and analysis of the basic model of hybrid learning,combined with the level of thinking ability of secondary vocational school students and elaborated the principles of model construction,on this basis,the hybrid learning model of computer basic course in secondary vocational school based on the cultivation of computational thinking is constructed.In the practical stage,we choose the computer application foundation course in the secondary vocational school to carry out the practical research on the mixed learning mode of the computer basic course in the secondary vocational school based on the cultivation of computational thinking.The application results show that the model has a positive effect.First,in the unified test after class,the performance of the experimental class is significantly better than that of the control class.Secondly,through classroom observation and teacher interview,it is proved that this model can improve the activity of the classroom,increase the enthusiasm and participation of students.Third,the results of the post-test questionnaire show that most of the students have improved their ability of calculating thinking and their awareness of thinking formation.
