Research On The Argumentation Teaching Model Of Chemistry In High School Based On Flipped Classroom

Argumentation is an important part of science education.Using argumentation to carry out teaching and learning is also one of the important directions of international science education research.In 2017,the chemistry curriculum standard for general senior high school issued by the Ministry of education clearly pointed out that it is necessary to strengthen students' advanced thinking ability and develop students' chemistry core literacy.As a new teaching mode,flipped classroom has changed the orientation of traditional teachers and students,rescheduled the classroom time,and realized the innovation of traditional classroom.However,both of them have not been widely practiced by chemistry educators.In order to get a more real practical effect,the author combines the domestic and foreign argumentation teaching,the research of flipped classroom and the current situation of practice,designs the high school chemistry argumentation teaching mode and the argumentation learning sheet based on flipped classroom.Guided by the concept of new curriculum standard,this model uses the ADI teaching model of scientific argumentation teaching for reference,takes the turmin argumentation model as the argumentation procedure and integrates the flipped classroom teaching mode to study the effective integration of argumentation activities and classroom teaching in middle school chemistry teaching.Based on the functional elements of turmin's argumentation model,the argumentation learning list integrates students' argumentation ideas,forms a written argumentation process,and helps teachers understand students' argumentation thinking process.In order to be more effective in teaching,this paper puts forward the necessary conditions and implementation suggestions for the implementation of the designed teaching mode.At the same time,three teaching cases are designed,which are the subject of "important compound of iron","reaction of metal and water","main role of inorganic non-metallic material silicon",and the teaching implementation of "important compound of iron".After the practice,the students are tested and demonstrated with paper and pen Ability test and learning attitude questionnaire.Through practice,it is found that this way can effectively develop students' core literacy,and play a positive teaching effect,not only to a certain extent,improve students' performance,but also improve students' argumentation ability and learning autonomy.This paper puts forward the implementation strategies of argumentation teaching based on flipped classroom from the aspects of scientific issues,efficiency of cooperative exploration,organization of argumentation thinking,etc.,hoping to provide new ideas for the development and innovation of chemical argumentation teaching in middle schools in China.
