Research On The Development And Design Of Junior Middle School Chemistry Innovation Experiment Micro Course In The Post Epidemic Era

The sudden outbreak of the novel coronavirus has brought a lot of inconvenience to people’s lives.In order to ensure that students’ study will not be disrupted,the country has put forward the requirement of "non-stop school suspension" for the development of the education sector,so as to minimize the adverse impact of the novel coronavirus on education.Education departments all over the country have responded to the call of the country,and quickly adopted the way of online teaching to organize students’ learning.During the epidemic period,the new combination form of Internet and education has brought a test to the information level of Chinese education,but also exposed the shortage of information level of some junior middle school teachers.At present,the information teaching level of junior middle school teachers is weak,and it is difficult to meet the learning requirements of students in the new era.Although the COVID-19 epidemic has been initially controlled in China,offline education has gradually resumed in all regions of the country.However,the epidemic has the characteristics of fast transmission and easy recurrence,so in the post-epidemic stage,online teaching and offline teaching gradually appeared alternate scenarios.When the epidemic was rampant,education authorities would organize teachers and students to carry out online teaching,which gradually resumed after the epidemic was brought under control.The two teaching methods will alternate due to uncontrollable outbreaks."Internet Plus" technology has been continuously integrated into the field of education.There is no doubt that the application of information technology in chemistry classroom and chemistry experiment teaching is an important development trend of chemistry education in the future.In the era of information development with the combination of education and the Internet,the birth of micro-lessons also conforms to the development trend of education.At the same time,as an innovative representative in the form and application of teaching resources,micro-class can truly provide accurate and convenient differentiated teaching services for every student due to its advantage of "fragmented teaching".With the promulgation of new curriculum standards,the continuous reform of junior high school chemistry experiment curriculum,and the increasing difficulty of chemical experiment teaching in the post-epidemic stage,this paper carried out a study on the design and development of junior high school chemistry innovation experiment micro-course in the post-epidemic era.The research of this paper is carried out from the following five aspects:On the first hand,after collecting and sorting a large number of literature materials,this paper focuses on the domestic and foreign research related to the development and design of chemistry micro-course and experimental micro-course,understands the existing research results and shortcomings,and clarifies the research content.Second,the two core concepts of micro-course and post-epidemic era are defined,and the development and design of junior high school chemistry innovative experimental micro-course under the background of post-epidemic situation are theoretically analyzed based on education theories such as constructivism theory and multiple intelligence theory,so as to analyze the feasibility of this research.The third aspect is the development and design of junior high school chemistry innovation experiment micro-course under the background of post-epidemic.This part mainly discusses the topic selection and design principles of junior high school chemistry experiment micro-course,and introduces its development process in detail.Fourth,based on the above topic selection and micro-course design principles,the micro-course case of junior high school chemistry innovation experimental teaching is designed and made.Including learning situation analysis,knowledge status,detailed teaching design and production process,and timely reflection on the problems in the design and development process.The fifth aspect is to summarize this research,summarize the results of this research,and reflect on the loopholes,hoping to provide more creative ideas for future research in this direction.This topic discusses the theoretical basis,topic selection strategy and design principles of the design and development of junior high school chemistry innovation experiment micro-course,and selects specific knowledge points from the teaching content of junior high school chemistry experiment for the design and development of micro-course.In addition,questionnaire survey and analysis were carried out on six classes of the school where the author works to understand the practical teaching effects of micro-lessons,and the teaching strategies applied in the teaching of junior chemistry innovation experiment micro-lessons were put forward.The research of this subject aims at constructing the design model of chemical innovation experimental micro-class teaching under the background of post-epidemic era,hoping to provide guidance and help for teachers to design and develop chemical experimental micro-course,.
