Design And Practice Of Chemical Experiment Micro-course Based On Flip Classroom

Since the 12 th Five-Year Plan of the Ministry of Education was put forward,teaching informationization has been applied in many aspects in educational nurseries.Teaching research and teaching control management all use educational information technology to promote the reform and development of education.In line with accessibility,sharing,interaction,cooperation and application,digital,grid and intelligent technology features,promote the education industry to keep up with the modern pace.The new modern education with information exchange and sharing has brought tremendous impact to the traditional field.It is reflected in that the educational industry and the teaching staff break the previous mode of thinking,change the teaching methods and ways,and improve the current form of teaching content.In order to meet the needs of modern personnel training,it creates a good atmosphere for improving the quality of education and training successors in the new era.Micro-class and flip-over classroom are new contents derived from this educational informationization environment.As the output source of high-quality courses,they are in the ascendant in the field of subject teaching.In this study,the introduction of micro-lessons into senior high school chemistry experiments based on the concept of flipped classroom is taken as the research direction,and the design and production of micro-lessons under the guidance of the concept and method of flipped classroom and the effect of its application in practice are explored and discussed.After searching,searching and referring to relevant literature,the research methods are based on experimental inquiry,questionnaire survey and data comparison.Based on Constructivism Teaching theory,systematization teaching theory,teaching information processing theory and cognitive load theory,this paper summarizes the principles of making micro-lesson video,and designs a process model of pre-production,teaching practice and application evaluation of micro-lesson.Through the design and analysis of specific cases,this paper further explains the design and production process of micro-lessons,and specifies the application plan of flipping classroom in teaching practice.In order to verify the specific effect of the implementation of Microteaching based on flip classroom in high school chemistry experiment,two peer groups were selected to verify the results in the research process,and data analysis method was used to compare the results.Through the research,it is found that students can accept the way of pre-class preview and after-class review in the flip mode.In addition,it is also found that learners have a positive role in guiding themselves through micro-lesson video learning,and can assist in learning and understanding in experiment.But at the same time,it is found that there are still some imperfections in the process of micro-teaching overturn.The author will further improve it through the follow-up practical teaching experience.This paper consists of six parts.Chapter I,Introduction.This paper describes the research background of this topic,elaborates the research status and meaning of flip classroom and micro class in detail,determines the research purpose and significance,research ideas and methods of this paper.Chapter two,the related theories of flip classroom and micro class are elaborated.By using the method of literature analysis,the research history and current situation of flip classroom and micro class at home and abroad are analyzed.Find the relevant education theory at home and abroad to provide the theoretical basis for this study.Then,in the third chapter,the design of chemical experiment micro-class based on flipped classroom is introduced.This paper designs a teaching model of chemical experiment micro-lesson based on flipped classroom,puts forward the principle of making micro-lesson,and explains in detail the design,development and production of micro-lesson.Chapter IV,the development and practice of micro-lesson cases based on flipped classroom.According to the model of micro-course design and production process,it is applied to practice,and the chemical experiment micro-course case is developed.Chapter five,based on the practical effect of Microteaching in flipped classroom.Evaluate the teaching effect.Chapter 6 summarizes and prospects.The research work of this paper is summarized and prospected.
