Research On The Practice Of Micro Course Guidance Model In High School Chemistry Teaching

Under the background of the new curriculum reform,classroom teaching advocates the teaching idea of taking teachers as the leading role and students as the main body,and pays attention to improving students' independent learning ability.Information technology represented by micro courses plays an important role in teaching,plays an auxiliary role in students' autonomous learning and has a wide range of applications,On the other hand,the learning guidance plan can stimulate the learning motivation,guide the learning path and find the learning problems.In order to explore the relationship between the integration mode of micro course and learning guidance plan and the improvement of students' autonomous learning ability and teaching efficiency,the author has carried out the following work:1.First of all,through literature review,this paper analyzes the research status and concept definition of micro course,learning guidance plan and learning guidance plan at home and abroad,and finds that the domestic literature has conducted a lot of research and design on micro course and learning guidance plan,but the research on micro course guidance plan in senior high school chemistry is relatively small and has a large research space.2.Taking senior one students and teachers as research objects,this paper makes a questionnaire survey from three aspects: Students' self-study status,understanding of micro courses and micro course teaching status,analyzes and summarizes the data,and finds that the application of micro course guidance mode in senior high school chemistry has certain foundation and feasibility.3.After consulting the literature,three strategies are put forward to integrate the micro course and the learning guidance plan:(1)combining the point with the surface,highlighting the key and difficultpoints.Micro class is the point,the explanation of knowledge points and key and difficult points in teaching,the carrier of teaching,and the guiding plan is the surface,which runs through the whole teaching process.(2)Create situations and stimulate interest.To create interesting scenes and stimulate students' enthusiasm for learning,the combination of learning guidance plan and micro class should arouse students' thinking and attract students to explore chemical knowledge through scenes and questions.(3)Answer feedback,improve teaching efficiency.Teachers and students participate in the teaching process together.There should be self reflection and detection links in the learning guide plan and micro course design,so as to increase the communication between teachers and students,preview and questions generated in the classroom process.In the classroom,students should answer the feedback questions in time,so as to improve the teaching efficiency.4.This paper analyzes the case of "redox reaction" and "important compound of sodium" in the chemistry textbook of compulsory one of human education edition.Redox reaction is selected from the content of section 3,Chapter 2 of compulsory one of human education edition.It plays an important role in the chemistry knowledge of senior high school and is the link of the knowledge of important elements and compounds in senior high school chemistry."Important compounds of sodium" is the first compound for senior high school students to systematically study elements.It is an extension and supplement to the knowledge of material classification,ion reaction and redox reaction in Chapter 2.It also lays a good foundation for the periodic law of elements,the structure of substances,chemical reactions and energy in compulsory two.Therefore,the arrangement of this class has the function of connecting the preceding and the following,and the contents of both classes have high research value and representativeness.In view of the different content setting and teaching objectives in the two classes,the micro class and learning guide plan are designed differently,and teaching practice is carried out in the teaching.5.In order to test the application effect of the micro course guidance mode,the author selected the senior class 16 of the practice school as the experimental class and the senior class 13 as the control class for the comparative practice study.The application of the micro course guidance model in the experimental class of grade 16,grade 13 is the traditional teaching model.Through statistical analysis of the middle and final grades of the two classes,observation and comparison of the classroom learning status before and after the implementation of the two classes,and interviews with students and teachers,it is found that the micro course guidance model has a certain role in promoting students' autonomous learning ability,improving the classroom learning status and teaching efficiency.6.Finally,the author summarizes and prospects the research.There is a solid theoretical basis for the micro course guidance model.In the conclusion of the study,it is found that it is helpful to improve students' autonomous learning ability,classroom learning state and teaching efficiency.Due to the lack of teaching experience,the design of micro course and learning guidance plan needs to be further improved.In the follow-up teaching work,we will continue to explore the application of the micro course guidance mode in high school chemistry,so as to optimize the teaching concept.
