Research Of High School Chemistry Micro-lesson Design And Application Based On Autonomous Learning

The new curriculum reform requires students to develop in an all-round way.and micro-course is the product of conforming to the requirements of The Times.Its purpose is to cultivate students' personalized learning and promote students' comprehensive development by centering on students.In order to strengthen the timeliness of education and improve students' learning autonomy,this paper studies the design and application of high school chemistry micro-course under independent learning.Selected high school chemistry content of "amount of substance","ion reaction" and "galvanic battery",according to the teaching objective and learning situation analysis,combined with the design principle of micro-course,designed and produced a total of 7 micro-course video cases of concept teaching type,problem solving type and experimental demonstration type,and carried out the teaching experiment of micro-course application.The application effect of micro course was tested by students' scores,questionnaire survey and interview.The analysis results show that micro-class can assist classroom teaching,extend classroom space and time,enrich learning methods,stimulate students' interest in learning,be conducive to students' independent learning,and effectively improve the teaching effect.This paper is divided into five chapters:The first chapter analyzes the current research situation of micro-course,elaborates the research situation of micro-course at home and abroad,the meaning and characteristics of micro-course,and explains the basis of topic selection and research significance.The second chapter defines the concept of autonomous learning and analyzes the theoretical basis of micro-course research.Including constructivism theory,humanism theory and lifelong learning theory.The third chapter describes the types of micro-lesson,micro-lesson design principles and micro-lesson recording methods,etc.According to the theory of micro-course design,high school chemistry teaching content was selected,and concept lecturing,experimental demonstration and problem-solving skills micro-course cases were designed and recorded respectively,and teaching strategies of different types of micro-courses were proposed.The fourth chapter studies the practical application of micro course cases,introduces the implementation method of micro course teaching,and analyzes the application effect of micro course through performance test,questionnaire survey and interview.The fifth chapter summarizes the harvest of micro-course research,reflects on the existing deficiencies,and looks forward to the future development prospects of micro-course.
