In The Flipped Classroom Teaching Of Chemistry Experiment In Middle School Practical Research Into NB Software

As an experiment-based subject,experimental teaching is an essential link in middle school chemistry teaching.At present,experimental teaching in middle schools is faced with problems such as less experimental classes,insufficient laboratory funds,and limited experimental teaching conditions.There is a "back experiment" for students ’ learning experiment,which does not meet the requirements of the new curriculum reform for talent training.Under the era of "Internet+education",the combination of Internet and education has provided new ideas for the development of basic education.Based on the basis of analyzing the current situation of chemistry experiment teaching in middle schools,this paper proposes the idea of integrating NOBOOK(hereinafter referred to as NB)software in middle schools,the purpose is to give full play to the advantages of the Internet,use information technology to make up for the shortcomings of traditional experimental teaching and provide new ideas for chemistry experiment teaching.The paper is mainly divided into the following parts:Part Ⅰ:Research Overview.Analyze the orientation of education policy and chemical experiment teaching,explain the advantages of NB software in middle school chemical experiment flipped classroom teaching,clarify the reasons of the topic selection,and analyze the research situation of flipped classroom and virtual simulation technology at home and abroad,determine the research purpose and significance,and put forward the research ideas.Part Ⅱ:Concept definition and theoretical basis.The concept of "flipped classroom" and"virtual simulation experiment" is defined,and "NB Virtual Experiment" and "NB Chemistry experiment" are introduced.At the same time,the theory of the "constructivism","learning effect pyramid" and "recent development area" is expounded.Part Ⅲ:The construction of the teaching mode.Questionnaire method and interview method were used to understand the current situation of secondary experimental teaching.According to the current situation of secondary experimental teaching,the teaching mode of NB software was constructed from the three aspects of pre-class preparation activities,curriculum implementation program and teaching evaluation.Part Ⅳ:under the guidance of relevant theory in middle school chemistry experiment into the case design of NB software,and choose two classes in a middle school in gansu as experimental object,the experimental class will design case "chlorine nature","chlorine gas of chlorine preparation","nature of thick sulfuric acid",the control class using the traditional teaching method to ensure the reliability of the experimental conclusion.Part Ⅴ:Analysis of the teaching practice effect.After the teaching practice,the classroom test results of the students of the two classes were analyzed and found that the teaching effect of the experimental class was better than the control class.The integration of questionnaire data and teacher interview results will study the application effect of virtual experiments and flipped classrooms in practical teaching.The results show that students and teachers have highly recognized this teaching mode.Part Ⅵ:Summary and Outlook.The research shows that the application of NB software in middle school chemistry experiment flipped classroom teaching is feasible in high school chemistry experiment teaching.It can not only have the core literacy of cultivate students"scientific exploration and innovation consciousness",but also improve independent learning ability and unity and cooperation ability,and enrich the experimental teaching mode.Although the research is not systematic enough when affected by personal level and time,we still hope that this research can provide some reference value for teaching.
