The Practice Of Flipped Classroom In Chemistry Experiment Teaching In Senior High School

Flipped classroom is a teaching mode that reverses the traditional teaching model of “teachers speak to students in classroom and do homework after class”,and turns it into “pre-class students' autonomous learning,group discussion and inquiry in classroom,and after-class expansion and extension”.This teaching mode takes the student as the main body,gives full play to the student's autonomy,and makes the student become the main character in the classroom.Chemistry experiment is one of the important teaching contents in middle school in the chemistry teaching.It not only helps students to deepen understanding and mastery of theoretical knowledge,but also hands-on experiment can cultivate students' practical ability and thinking ability.Through the investigation and interview of the students in the practice school,it is found that there are some problems in the chemistry experiment teaching in senior high school,such as lacking of teaching hours,poor students hands-on ability to do experiments,insufficient attention by some teachers,and imperfect hardware facilities in the school.On the basis of the characteristics of students cognition and thinking,combining with the advantages of chemistry experiment teaching,this paper is based on learning pyramid theory,recent development area theory and cooperative learning theory,putting forward the basic steps of the application of the practice teaching in the flipped classroom,and on the basis of this,completes the practice teaching.The teaching design of “preparing solution of concentration of certain substance” and “important compound of iron” were designed,and the teaching practice was carried out in the first grade of senior high school in practice school.For the effect of the flipped classroom practice teaching,this paper evaluates and analyzes the students' attitudes and ability improvement in the whole learning process through questionnaires.The practice results show that: for students,in the study of flipped the classroom teaching mode,it is possible for them to be able to stimulate the enthusiasm of students to participate actively and to verify the phenomenon of video demonstration experiment.It creates opportunities for students to experience the process of inquiry and stimulate innovative thinking,so that students can achieve a sense of achievement.As far as teachers are concerned,the development of this teaching mode is conducive to promoting teachers' multi-angle,in-depth expansion of classroom teaching content and their own professional knowledge,and promoting the development of teachers towards research-oriented direction.In the aspect of experimental teaching,on the basis of mastering the experimental knowledge,the students' diversified activities not only provide students with the opportunity of hands-on practice,but also provide a platform for the cultivation of students' knowledge transfer ability and the use of hands and brains.The case study of this paper,there are certain practical significance to the application flipped classroom teaching mode in chemistry experiment teaching in middle school.
