Teaching Case Study For Flipped Classroom Of The Experimental Chemistry

With the rapid development of information technology and the continuous renewal of educational concepts,the combination of information technology and education has become more and more closely,and society has become more and more demanding for the cultivation of talents.With its unique advantages,flipped classroom has adapted to the development of educational informatization.Under this background,the teaching model of flipping classes was introduced into the teaching of experimental chemistry courses at Shihezi University.In order to reduce students' pre-learning flow in form,copying books and other phenomena;improve the pertinence of teacher's lectures and promote the interaction between teachers,students and students;and reduce the number of students still unable to answer the questions and questions in the experiment after the experiment.This paper introduces the research background and the origin of the topic,summarizes the related research status,expounds and analyzes the relevant concepts and theoretical basis and the common model.On this basis,the principles and ideas for the design of the pre-implementation case,task sheet,lesson plan,and extension column are summarized and the teaching model of experimental chemistry flipping is proposed,and combined with the teaching content to be put into practice.The design of two experiments,"preparation of ammonium ferrous sulfate" and "preparation of crude salt," was given,and evaluated both cases when they were implemented.Taking the first-year non-chemistry undergraduate students at the 2017 University of Shihezi University as the research object,the literature,experiment,investigation,and other research methods were used to analyze the implementation effects of the flipping classroom teaching model in the experimental chemistry curriculum.The analysis of the experimental chemistry flip classroom teaching results includes two aspects,namely,the investigation and analysis of the preparatory work before the implementation of the experimental chemistry flip classroom and the investigation and analysis of the three-dimensional goals achieved by the flip classroom teaching.The research results show that the design of the academic case,task list and extracurricular resources before the implementation of the overturned classroom is reasonable and it helps to guide students in pre-class study and achieve a better preview effect.Studies have shown that flipping the classroom shifts the main body of activities to students.This not only enables students to acquire a more solid knowledge and a more reasonable learning method,but also enables them to gradually develop students' comprehensive ability in analyzing problems,cooperation and exchange,and at the same time creating a good environment.The atmosphere of the classroom enabled them to obtain a good emotional experience and formed a positive attitude and correct values,thus achieving a good three-dimensional goal.In the end,the author puts forward corresponding suggestions for the insufficiency of flipped classroom teaching,in order to be corrected and improve the teaching effect.
