The Study Of Presupposition In The Chemistry Teaching In Senior Middle School Under The Background Of The Network

This paper tries to study how in the network background of senior high schoolchemistry teaching presupposition, exploitation and how to carry out the cyber source inchemical teaching design in the preset. To achieve the teaching goal, teaching effectively,must carry on the effective integration of curriculum resources. So teachers must becomethe master of integration of curriculum resources, teaching high school chemistrypresupposition, to promote the new curriculum, the implementation of effective teachingachievement. Network information technology is an important means of effective teachingcurriculum integration. How to integrate the network data and the new curriculum, andgive full play to the modern network information technology support to the newcurriculum.The research is divided into six parts. The first chapter is the definition of the coreconcept. And the vieus of Domestic and foreign scholars on teaching presupposition andteaching design. Under the background of the network teaching’s presupposition withtraditional lesson preparation, We can prove the necessity of teaching is in default underthe background of the network. The second chapter is the study of presupposition teachingunder the background of internet. Piling up of network data, teachers relying on thenetwork, in the teaching design of over use of resource utilization, caused the classroomwith large amount of information, students of auditory fatigue, debsement of theeffectiveness of teaching. The third chapter is the theory research on the teaching ofpresupposition. Based on the system theory, communication theory, constructivism theory,theory of connectivism learning research, We can seek the theory basis of constructing andpresupposition teaching optimization under the background of the network. In addition,digging out the research track related to this topic, useing the existing research results,formthe basic support and research based on this research. The fourth chapter is the study on theexploitation and utilization of network resources in the teaching of chemistry preset.Through the analysis of Chemistry Teaching in the role of the default network resources, and network teaching resources preset selection and integration, and the rationality of the"allotropes" this teaching design,We can perform of network resource selection andintegration. The fifth chapter is the study of presupposition of Chemistry Teaching underthe background of the network, mainly including the analysis and Research on theprinciple and content of the teaching of the design. The sixth chapter is the analysis of thedesign of a default case teaching, through the teaching design of "case of electrochemicalcorrosion and protection of metals to demonstrate" network data selection and chooseDelete the necessity and rationality, and through the teaching reflection on existing flippedclassroom teaching problems in.Finally, this article has carried on the analysis and reflection on the shortcomings inthe study, for the future research trend was prospected.
