Extracurricular Applied Micro Solve The Junior Middle School Chemistry Class Problems Of Difficult Research

The micro-course is an important result of the development of the networked,shared and open educational resources,conforming to the basic education curriculum reform idea and the educational information development trend.In recent years,there have been lots of mini-course websites and various mini-curricula competitions.However,how to combine micro-courses with subject teaching is less and less,and the research on micro-courses focuses on the characteristics of idea,production and development.Level,combined with the junior middle school chemistry is very lacking,the actual teaching effect has yet to be verified.Based on this,this paper to junior middle school chemistry as the academic background,to study the following questions:1.Junior middle school students' knowledge and needs for micro-class?2.How to design and develop micro combined with junior middle school chemistry?3.Practical effect of extra-curricular application for micro-problem solving junior high school chemistry problem?In order to solve the above problems,this paper is divided into six parts:the first part is the introduction,mainly from the implementation of the new curriculum reform,educational information and curriculum resources development background,illustrates the research background,purpose and significance.And introduces the research contents and methods of this paper.The second part is the summary of the literature,defines the concept of micro curriculum,sums up the domestic and foreign research literature on micro curriculum,and puts forward two theoretical bases of constructivist learning and autonomous learning.The third part is the investigation and analysis of the junior middle school students' cognition and demand of micro-courses,and selected Wuhan C Middle School as the case study.The questionnaire survey and analysis are made on the basic situation and the cognition and application of the ninth-Master the first-hand information and material.The fourth part is the design and practice of microcosmic problems in junior middle school chemistry.On the basis of discussing the design principle,development process and recording to method of the micro problem in junior middle school chemistry,the micro teaching case is designed,and the application of micro-The implementation of chemical problems.The fifth part is the evaluation of the effect of extracurricular application of micro curriculum on junior middle school chemistry to solve the difficult problem.It is mainly through the follow-up of the experimental class and the control class.By means of test questions,questionnaire and teacher interviews,practical problems of difficult results.The sixth part is conclusion and enlightenment,elaborated the main research conclusion of this article,put forward the suggestion to the design and application of junior chemistry micro course.Through the research,this paper draws the following main conclusions:1.In the micro-level cognitive and demand level,junior high school students have a large number of mobile network equipment,while large "early high" pressure also requires students to use extra-curricular time for self-learning;learning chemistry encountered the biggest problem It is expected that micro-lessons will be applied to experimental teaching and difficult problem solving,and hope that subtitles,teachers'headlines and related 1-2 micro-exercises can be found in micro-lessons,and hope that interact with teachers through the real-time chat tools.2.The design and development of micro-class insists on the selection of students recognized teachers,the topic should be accurate and consistent with micro-teaching,control time strictly and micro-system design resources to complete the system and other principles,based on pre-analysis,Students self-learning,evaluation feedback process development.3.Extracuuricular application practice of micro curriculum to solve the problem of junior middle school chemistry difficult shows that the micro curriculum for difficult problems in the chemistry of extra-curricular students self-learning,can play to stimulate student interest in learning,improve student learning ability and learning effect,but also help to enhance the professionalism of teachers and information technology applications.This study provides a reference sample for the design and development of micro curriculum in junior middle school chemistry.It also helps to promote the application and development of micro curriculum in school teaching and students' self-study.It has important theoretical and practical significance.
