Research On The Application Of Blended Teaching In The Course Of "Graphic Image Processing" In Secondary Vocational Schools

At present,the information construction of education in China has entered a new era and a new stage.The deep integration of education and information technology is constantly pushing education to achieve high-quality innovative development.As an important part of China’s education system,the development of vocational education is also receiving more and more attention,and the state has introduced many policies to promote the reform and development of vocational education.As a core course of secondary computer science,the course of "Graphic Image Processing" with Photoshop software as the main learning content occupies a very important position in the curriculum construction of secondary vocational education.However,in the actual teaching process,the course still adopts the traditional "teacher"-centered face-to-face teaching,which has the phenomenon of low learning efficiency and poor learning effect of students.In the face of the modern society’s demand for secondary schools to cultivate high-quality,highlevel and high-skilled vocational and technical talents,the middle-level Graphic Image Processing course urgently needs to use modern information technology to reform its teaching.In this thesis,we sort out and analyze the theories related to hybrid teaching,and according to the teaching status of the middle-level Graphic Image Processing course,we applied the hybrid teaching on the middle-level Graphic Image Processing course,and the main work is as follows:Firstly,the literature research method was used to collect and review data,summarize the current situation of domestic and foreign research on blended teaching,related concepts and theoretical foundations,and sort out the research ideas and research contents.Secondly,we use questionnaire,interview and observation to investigate the teaching status of the middle-level Graphic Image Processing course,summarize the problems in teaching,and analyze the necessity and feasibility of applying hybrid teaching in the middle-level Graphic Image Processing course.Again,combining with the characteristics of the middle-level Graphic Image Processing course,Study Talk is selected as the online teaching platform and a Photoshop image grading system that can grade students’ subjective questions is designed;based on the dual teaching platforms,this study carries out a new hybrid teaching design for the middle-level Graphic Image Processing course.Finally,in order to verify the effectiveness and feasibility of hybrid teaching,two classes with the same basic situation were selected to carry out a controlled teaching experiment in this study,and the effectiveness of hybrid teaching was evaluated and analyzed through performance analysis and questionnaire survey.The experimental results show that it is effective and feasible to apply blended teaching in the middle-level Graphic Image Processing course.Blended teaching can effectively improve the teaching status quo,enhance the teaching quality and participation in class,and promote students’ self-learning ability and self-control ability.
