Research And Practice Of Mixed Teaching Of Graphics And Image Processing In Secondary Vocational Schools Based On Mobile Terminal

With the continuous development of modern information technology,educational informationization has become the focus of research in the field of education.How to make use of educational information to improve teaching quality is also a key breakthrough in China’s secondary vocational education reform.Graphics and Image Processing has higher requirements on the practical operation skills and creative ability of secondary vocational students,and it is also one of the required courses for art and computer majors.Under the traditional teaching mode,the teaching of this course has some prominent problems,such as students’ high learning interest but poor teaching effect,students’ lack of independent learning ability,students’ less participation in the interaction of classroom teaching,students’ great differences,and students’ weak practical ability and innovation ability.Therefore,it is difficult to achieve high quality teaching objectives.Modern composite teaching mode combining "online teaching" and "offline learning" advantage,can provide students with abundant learning resources and communication technology platform,students can according to own situation purposefully autonomous learning,can not only ensure the dominant position of students’ learning,but also can play the advantages of traditional teaching pattern offline.Therefore,the application of the hybrid teaching mode based on mobile terminals in the teaching reform of Graphics and Image Processing in secondary vocational schools in this study can promote the continuous improvement and innovation of the course.This paper adopts literature analysis method,questionnaire survey method,action research method and interview method to conduct research and practice on the course of "Graphic and Image Processing" in secondary vocational schools based on mobile terminals mixed teaching.The specific research process and results are as follows:First,theoretical research.Expounds the research background,research status at home and abroad,research purpose and meaning,research contents and methods of this article,the related concepts(teaching informationization,the hybrid mode)defined,and a variety of learning theory to the teaching of support hybrid in-depth analysis,providing theoretical basis for teaching model in this paper,the hybrid design and guidance.Secondly,the secondary vocational "graphics and image processing" course mixed teaching investigation and research.Based on hybrid teaching can effectively combine the characteristics of online learning and traditional offline advantages of classroom teaching,introducing hybrid teaching "image processing" course teaching in technical secondary school,the first design the questionnaire and interview outline of the current secondary vocational computer professional teaching and learning of the graphic image processing,then collect questionnaire and interview data and analysis,and finally summed up the graphic image processing in the secondary vocational computer professional course,analyzing the problems in the current teaching the necessity and feasibility of application of the hybrid teaching and students’ preference for hybrid teaching requirements,It provides the basis for the design and practice of mixed teaching based on mobile terminal.Thirdly,the hybrid teaching mode based on mobile terminal is constructed.According to the characteristics of the course of "graphics and image processing",the advantages of mixed teaching are analyzed,combined with the advantages of mobile terminals,relying on the learning teaching platform,the design of mixed teaching application suitable for secondary vocational "graphics and image processing" is constructed.It is mainly divided into four parts: teaching preparation analysis,teaching resource design,teaching activity design and teaching evaluation design,and the components and implementation process of each part are elaborated in detail.Finally,the practice research based on the mobile terminal mixed teaching.The author applied blended teaching in the course of Graphics and Image Processing of the computer major of X Vocational School in Guilin City.Through action research method,the author carried out three rounds of action research,and constantly observed and reflected in the action to improve the blended teaching design.Through the interview method,the feelings and suggestions of teachers and students in the blended teaching were obtained to verify the effectiveness of the blended teaching model designed in this study.The practical results show that the application of the hybrid teaching mode based on mobile terminal in the secondary vocational "graphics and image processing" course is effective,which can improve the students’ learning efficiency,autonomous learning ability and classroom participation,improve the teaching status and enrich the teaching resources.
