The Design Research Of Junior High School Chemistry Teaching For Understanding Based On Smart Learning System

Smart learning system supported by information technology,has a record and analysis the function of teaching data and rich teaching interactive tools,at the same time provide rich teaching resources for classroom teaching,for students and teachers classroom teaching interaction,classroom teaching activities such as classroom teaching evaluation feedback to provide support,improve the students' learning enthusiasm and initiative.Junior high school chemistry is a basic natural science subject in the compulsory education stage,an important subject to develop students' scientific literacy,and also the basis of chemistry learning in the next stage.Students' understanding of chemistry is the basic premise for the application and transfer of knowledge,the formation of thinking methods and the development of literacy.How to make use of the rich functions of the smart learning system to serve the understanding learning and understanding teaching and effectively promote the development of junior high school students' scientific literacy is a problem worthy of in-depth study.By consulting and summarizing relevant domestic and foreign literatures,this study firstly summarized the current research status of smart learning,smart learning system and understanding teaching at home and abroad,clarified the purpose,content and significance of the research,and conceptually defined smart learning and smart learning environment.Secondly,the theoretical basis of understanding teaching based on smart learning system is expounded.Then,based on the analysis of the functions and effects of the smart learning system and the research and analysis of the typical understanding teaching model,the understanding teaching design and implementation model based on the learning system is constructed,and the components of the model are expounded.Finally,the model was used to conduct a teaching experiment on a middle school in Qinzhou city.The experimental class was guided by the understanding teaching design and implementation model based on the smart learning system,and the control class used the traditional teaching model.The author analyzes the classroom teaching situation,students' homework performance and exam scores of the two classes,and the results are as follows :(1)the classroom teaching atmosphere,students' speaking situation and students' and teachers' and students' interaction situation of the experimental class are better than those of the control class;(2)the experimental class was higher than the experimental class in terms of chemical terms(P=0.02<0.05)and chemical experiment(P=0.034<0.05).In addition,the experimental class was also more accurate than the control class in terms of partial understanding of the three questions,but the control class was more accurate than the control class in terms of partial understanding.(3)the standard deviations of the test results before and after the experimental class were 15.8 and 15.5,and those of the control class were 19.2 and 22.0,respectively.The box chart was used to analyze the post-test results of the two classes,and the median of the data was 86.0.Based on the analysis and summary of relevant data,the comprehensive chemistry teaching in junior high school based on smart learning system has the following advantages and limitations :(1)Advantages.(1)Active classroom atmosphere of teaching and learning,to mobilize students' learning enthusiasm and initiative,improve the efficiency of classroom teaching,to a certain extent,can help students' understanding of the content of chemical knowledge,promote the application of subject knowledge and migration,development student the dimension of subject understanding,promote the formation of discipline concept and academic thinking,developing scientific literacy.(2)Reduce the class two levels of differentiation,promote the balanced development of all students.(3)Can make the professional level of teachers to develop and improve,to help teachers improve information literacy.(2)Limitations.The functional features of the smart learning system will speed up the process of teaching activities,and students' thinking time will be interrupted by classmates or teachers.The depth and breadth of students' thinking are not enough,and some problems or phenomena are not deeply thought and analyzed,and the depth of learning is not enough,resulting in unbalanced development of students in different dimensions of understanding.This study has achieved preliminary results,but there are still shortcomings.Due to the limited time and energy of the author,the research time is only more than three months,and the research content and object only involve two classes in junior high school.Therefore,the integration of smart learning system and understanding teaching in chemistry classroom still needs further research and development.It is hoped that this study can provide a strong reference for the combination of learning system and chemistry classroom teaching in junior high school.
