Research And Practice Of Mixed Teaching In High School Chemistry

According to the deepening of basic education reform and the popularization of Internet in practical teaching,blended learning teaching method has gradually been applied to teaching practice.Blended teaching is to combine the traditional classroom teaching with online learning,giving full play to their own advantages,stimulating the students' enthusiasm for the study of chemistry,and promoting the communication and interaction between teachers and students.In the teaching of chemical experiments in high school,the mixed teaching method is beneficial to the integration of school and parents' teaching resources.It is also beneficial to the complementary advantages of these elements.This is also beneficial to the profound influence on the reform of basic education.This paper is divided into the following six parts.The first part,through the review of the literature on "mixed teaching" at home and abroad,analysis of the current research status of mixed learning at home and abroad,and on the basis of previous studies,combined with the teaching practice of high school chemistry experiment to put forward the breakthrough point of this thesis,and clarify the significance of this paper.The second part is mainly to define and explain the related concepts of mixed teaching,focusing on the theoretical basis of the mixed teaching mode,so as to explore the essence of the mixed teaching,and combine the high school chemistry experiment class with the mixed teaching.The third part,focusing on the theoretical analysis and design of mixed teaching,that is,the theoretical analysis and design of the various links and learning resources of the mixed teaching method,so as to build a mixed teaching model with the characteristics of chemistry.The fourthpart,taking a class of educational practice in the school as an example,in the teaching process,the use of mixed teaching method to explain the experiment,in addition to the use of mixed teaching in the teaching,the author in the classroom to students to ask questions,observe students understanding of the knowledge point.Collect experimental data from students,such as pre class guidance,classroom response.They handed experimental results,experimental data,experimental conclusions,and the completion of experimental reports after class.After a sample interview with parents,the author compares the experimental data with other classes in the same period.At the same time,the video and related data will be uploaded to the shared database.After the experiment,the teacher summarized all the data,summarized the effect of the mixed teaching method in the course application,and improved it according to the opinions of the parents.The fifth part is mainly the analysis and summary of the teaching practice,through the questionnaire survey of the first-line chemistry teachers and the feedback from the parents of the students in the actual teaching process.Obtain the research data of this study.According to the in-depth analysis of the current high school experimental teaching model and the merits and demerits of the actual analysis,the practical role of the mixed teaching method in the teaching of chemical experiment teaching is designed,and the corresponding teaching cases are constructed,and the results are summed up according to the problems encountered in the specific case.Based on the analysis from the theory to the practice,it is concluded that the mixed teaching is popular and supported by the students in the information age.The application of mixed teaching in the high school chemistry experiment classroom can improve the quality of students' independent study and cooperative inquiry,and can effectively promote the students' understanding of knowledge.In addition,the mixed teaching is beneficial to the construction of the concept of chemistry and the improvement of the quality of chemistry teaching.
