Study On The Chemistry Bridging Teaching In Junior And Senior High School Based On SPOC

Junior and senior high school chemistry connection is of great significance for the overall planning of the two learning stages,the sequential progression and the orderly transition of the two learning stages.Curriculum standards and relevant documents for linkage teaching put forward clear requirements,however,due to various practical reasons such as different stages,environments,teaching methods,students and limited time,there are still gaps in chemistry teaching in junior and senior high schools.Although there are a lot of researches on it,they are just talking about it and have little effect on the connection between junior high school and senior high school.In this context,online education infuses new blood into education with its unique advantages,and SPOC teaching is effective in college teaching practice with its diversified and personalized teaching methods,and it is suitable for solving some problems.Therefore,this study adopts SPOC teaching method to solve the problem of linking junior and senior high schools through the combination of online and offline modes,so as to improve students’ learning autonomy and cultivate their interest in learning chemistry.This study takes the design of SPOC linkage teaching as the approach,with the ultimate goal of promoting students’ independent learning and solving the problem of chemical connection between junior and senior high schools.Based on a large number of reviews and analyses of the relevant literatures and the current situation of connection between junior and senior high school,the disconnections and connections of junior and senior high school chemistry are summarized and sorted out.On this basis,"redox reaction" was selected as an example to carry out SPOC linkage teaching design,and its effect was evaluated through the study result table and the questionnaire.The practice shows that:students can take the initiative to learn by themselves online by using SPOC teaching;Design a variety of learning methods for students to choose their own,increase students’ learning enthusiasm and improve learning interest;Conduct teacher-student discussions and student-student discussions online,increasing communication between teachers and students,and between students and students;By reviewing junior high school knowledge online before class,learning new lesson knowledge offline during class,and reviewing senior high school knowledge online after class,junior and senior high school chemistry knowledge has been well connected.Therefore,it is feasible to use SPOC teaching to solve the problem of chemical connection between junior and senior high schools and improve students’ autonomous learning ability.
