Research On The Application Of Middle School Chemistry Virtual Experiment Teaching Based On NOBOOK Platform

This research focuses on the chemistry virtual experiment of middle school as the research object,emphatically studies the instructional design of the middle school virtual chemistry experiment based on NOBOOK,the application of teaching practice and the learner effect analysis.In the virtual experiment environment supported by the virtual experiment technology,combined with situational cognition theory,activity theory and comparative experimental teaching method,through the practice of virtual chemistry experiment teaching in No.42 middle school of Zhengzhou,this paper explores the effect of virtual experiment in chemistry experiment teaching,and provides the theoretical basis and tool method for the development of chemistry virtual experiment teaching in middle school.The structure of this paper is divided into six parts: he first chapter introduces the research background and significance,the question and the methods used in the research process.The second chapter describes the related theories of this study and the NOBOOK virtual experiment platform.It introduces the process of virtual experiment in NB Chemical Lab in detail.In chapter three,designs the virtual experiment teaching mode based on the activity theory,analyzes explains various links in the teaching mode.The fourth chapter is based on the virtual experiment teaching model for teaching design and application,select the pollution gas-chlorine gas production as the research case,design the chemical virtual experiment teaching design scheme,according to the teaching design scheme,carry on the practice teaching in the Virtual Laboratory of the NB chemical laboratory.The fifth chapter analyzes the effect of virtual experiment teaching through classroom observation records,experimental report and questionnaire data in the virtual experimental teaching activities.The sixth chapter is the conclusion and deficiency of the research,which point out the direction of the next step,and explains the value and innovation of the research.The research results show that the teaching method of virtual experiment is feasible and effective in chemistry experiment teaching in middle school.It can make students proficient in experimental operation skills,improve experimental practice ability,and effectively solve the problem that experimental teaching is not timely,and helps students to carry out personalized learning.It is helpful for students to carry out individualized learning,and it is expected to provide certain reference to the future experiment teaching of middle school chemistry teachers.Meanwhile,the research is new field and exploration of the integration of information technology and chemistry teaching in middle school,which has high practical significance and application value.
