Research On Project-based Teaching In Secondary Vocational Schools Under Blended Learning Environment

The state promulgates special documents to accelerate the development of modern vocational education and encourages and supports the implementation of project-based teaching in secondary vocational schools.Project-based teaching is highly respected by teachers in secondary vocational schools because it pays attention to students’ active participation in project design and implementation,active participation in new knowledge exploration and ability training,and at the same time examines the theoretical knowledge of disciplines and the working ability required by vocational posts.At the same time,the state has issued special documents to support the informationization of education,giving full play to the supporting and leading role of information technology in the project-based teaching.Cloud computing,big data,ubiquitous network,Internet of Things and other new generation of information technology are increasingly popular and mature applications,such as micro-courses,Mu-courses,SPOC,excellent courses alliance,etc.Online learning resources with strong interactivity and abundant content provide abundant learning materials for new teaching modes and learning modes such as flipping classroom,mixed learning and intelligent learning,and construct interactive communication space for students’ pre-class preview,autonomous learning,inquiry learning and after-class defect checking.The new generation of information technology and the rich on-line learning resources provide technical and resource support for the project-based teaching based on the blended learning environment.The purpose of this study is to optimize the project teaching process based on the blended learning environment,to expand the studentsundefined learning space and to extend the classroom teaching time.Stimulate the studentsundefined learning potential and improve the teaching effect of the project.First of all,this paper introduces the research background,research purpose and significance,research content and methods,defines the relevant concepts,discusses the current situation of the research,and introduces the theoretical basis of the research,namely: constructivism theory,connectionism theory,educational communication theory,cooperative learning theory.Secondly,it introduces the project-based teaching in secondary vocational schools,designs,distributes,statistics questionnaires,and makes diagnosis and Attribution analysis of the problems,that is,resource sharing is limited by time and space,studentsundefined learning channels are single,studentsundefined subjective role is limited,information acquisition is slow,interaction between teachers and students is single,and there is no large interactive learning space.All teaching links focus on classroom face-to-face teaching(training site)learning time.Thirdly,the project-based teaching design scheme in the blended learning environment is designed and determined,and Baihui Cloud Learning platform is selected as its online learning platform to collect,gather and produce a large number of appropriate learning resources uploaded and pushed to the online learning platform for students to learn independently and deeply.This paper designs the online learning activities and the classroom face-to-face learning activities,and corresponding to this,designs the online learning evaluation method and the classroom face-to-face learning evaluation method,and deduces and summarizes the project teaching structure diagram in the blended learning environment.The "skill training project" and "comprehensive training project" are selected as the project teaching cases in the blended learning environment.According to the difficulty and complexity of the project,this paper analyzes their respective learning contents and learning objectives,and designs the teaching process,learning activities and learning evaluation methods suitable for their own characteristics.Finally,the "chisel hammer making" project and "Taiwan vice making" project are selected as the teaching practice items of "skill training project" and "comprehensive training project",and the teaching effect of the project in the blended learning environment is analyzed in detail,the experience is summarized,and the research conclusion is given.The research shows that based on the blended learning environment,the project teaching is carried out,the online learning platform across time and space is built,the studentsundefined learning space is expanded,the classroom teaching time is extended,the studentsundefined learning activities are extended,the promotion activities are extended from 45 minutes in the classroom to the broad extracurricular period,the studentsundefined learning channels are diversified,the resource sharing breaks through the limitation of time and space,and the information is obtained more quickly and flexibly.The way of teacher-student interaction is rich and diverse,and the subjective role of students has been brought into full play.A considerable number of studentsundefined spare time has changed from focusing on playing games on smart phones to making full use of the online learning platform to learn the theoretical knowledge necessary for the implementation of the project,thinking about how to implement the project,arousing studentsundefined innovative potential and interest in learning,promoting studentsundefined analysis and problem-solving ability.It meets the needs of post professional accomplishment and post operation skills,and provides practical support for further promoting teaching reform.
