The Practice Research In The Senior Middle School Chemistry Teaching Of The AB Class Based On The Flipped Classroom

The flipped classroom is a new teaching mode different from the traditional classroom.Because it accords with the demands of the development of education and teaching reform in our country in the new period,meet the needs of the development of students,and is consistent with the current training goal,the flipped classroom teaching model is gradually explored and applied in various disciplines.The application research in chemistry curriculum is an important component of the whole,and conducive to the accumulation of experience in the model in different disciplines and characteristic development.An introduced teaching model emphasizes the local digestion and development in teaching practice,and has the vitality and good effect leading to applicable and popularization value.Based on the autonomous learning,constructivism and the concept of flipping the classroom,we stated the practice research of flipped classroom and it in chemical teaching,summarized the problems existing in the practice research of flipped classroom,and analyzed the reasons putting forward the corresponding solution strategy.On the basis of the theory analysis,we proposed the AB class based on the flipped classroom and build the model flow chart.Using contrast experiment study method,we did the AB class based on the flipped classroom and the flipped classroom(did it after and in class).I did the flowing research.Firstly,I plant the implementation steps of the AB class based on the flipped classroom and summarized he experimental research.Secondly,I set an experimental class and a comparative class,teaching respectively in the AB class and the flipped classroom(did it after and in class).I selected three teaching cases,the amount of substance in theprocess of practice,the redox reaction,and the inspection of SO42-to show the practical process in the form of classroom activity.Thirdly,I analyzed students' process performance from the average number of watching,the autonomous learning task,and the average number of problems in group,testing the result by comparing the grades before and after.I analyzed comprehensively and got the practical conclusions.Practice results showed that the AB class generally has a good effect to students,guarantees the independent learning efficiency of students,also makes the class knowledge internalization go orderly.The AB class can effectively solve the problem of insufficient extracurricular time for students.In the process of practice,students' learning atmosphere is very easy,and learning method is very flexible,not rigid in the traditional model that students listen to the teacher.The process truly reflects the dominant position of the teacher and the students' subjectivity.
