Design And Application Of Micro Lesson Case In Middle School Chemistry Teaching Based On Animation Software

With the advent of the Internet age and the popularization of information technology,the application of modern educational technology in primary and secondary school teaching as well as in university teaching has gradually become the focus of education.Among them,micro lessons have attracted wide attention from educational scholars due to their short and fine features.The micro lessons meets the cognitive load of primary and secondary school students' learning,helps students build their own knowledge,and promotes the students' ability to learn independently.In 2012,the flipped classroom with micro lessons as the main carrier raised a wave in the country.Then,with the rise of MOOCs in Chinese universities,the emergence of micro lessons related software and the update of its tutorials,the gradual introduction of micro lessons into primary and secondary schools and college classrooms has become one of the necessary skills for current teachers.The chemistry learning focus on understanding the nature and structure of students of material,visual presentation is more,such as chemical formula writing,material presentation,chemical reaction principle analysis requires specific cases,modern educational technology needs support.Micro lessons can meet the needs of chemical learning,and the contents of chemistry can be vividly presented.With the emergence of vocabulary such as animation synthesis software,linear presentation,and visual expression,the form of micro lessons has added new forms of presentation.In this article,we will introduce three animation-based micro lessons production software that is easy to operate and presents with a specific case.It introduces the software use process and the process and ideas of micro lessons design in detail,and applies micro lessons to classroom teaching.The significance of the research of this topic is to introduce three animation softwares and apply them to the production of micro-classes,in order to enrich the presentation form of micro-classes,and combine related theories to conduct curriculum teaching research.The research methods are literature review and data analysis.The specific process is to summarize the predecessors' research on the micro-curricular and animation software applications,and to combine the relevant theories and predecessors' research on the application of micro-curriculum practice process to carry out process design and analysis the experimental results.The research results show that during the course of classroom teaching using animated micro-classes,students not only mastered the course knowledge,but also had a relatively strong interest in learning in microclasses.The specific content of this study is divided into the following five aspects:The first part: through literature research and investigation of a number of domestic and foreign research status of micro lessons animation and micro lessons for statistical analysis,academic research on micro lessons in practical application and scholar teaching in elementary and middle schools with micro lessons,so as to determine the research purpose,significance,contents and methods.The second part outlines the definition and characteristics of the micro lessons,and the overall production requirements of the micro lessons.It also discusses and explains the theoretical support of the subject,such as cognitive load theory,constructivism theory,autonomous learning theory and so on.The third part is to summarize the common presentation types and production process of micro lessons,and to introduce the methods of making each kind of micro lessons.This paper focuses on the introduction of the methods of using the Crazy Talk,Powtoon and Explaindio Video Creator animation micro-Lesson making software.The fourth part,combined with the principle of micro lessons making,the basic theory of micro lessons learning and the three kinds of micro lessons software in the third chapter,the course analysis and micro lessons are made.The fifth part,through tests and interviews,analyzes the use of different types of micro lessons cases in a middle school,summarizes the experience and shortcomings based on the analysis results,and puts forward suggestions and strategies for middle school chemistry combined with micro lessons.
