The Investigation And Practical Research Of The Core Literacy Training Status Of "evidence Reasoning And Model Cognition" In Senior High School Chemistry Teaching In Qiannan Prefecture

The cultivation of core literacy is the main goal of the Chemistry Curriculum Standard(2017 Edition)of General Senior High School,which guides the direction of the new curriculum education and teaching reform.The core accomplishment of chemistry is the key accomplishment in solving the problems related to chemistry in the development of students' cognitive activities."Evidence reasoning and Model Cognition" is one of the core qualities of chemistry.It is an important way and method to cultivate students' core chemistry literacy by integrating evidence reasoning and model cognition into senior high school chemistry teaching activities,cultivating students' awareness of evidence reasoning and model cognition,and internalizing model cognition and evidence reasoning into an inherent learning style.Qiannan Bu,Guizhou Province According to the ethnic and Miao Autonomous Prefecture(hereinafter referred to as Qiannan Prefecture)is an economically underdeveloped minority area,the basic chemistry education is relatively weak.It is of positive practical significance to improve the core accomplishment of high school students' chemistry subject and promote the all-round development.The subjects of this study are chemistry teachers and students in Qiannan senior high school.Based on the research methods of literature research,investigation research and practice research,this paper focuses on the cultivation of "evidence reasoning and model cognition" core literacy in Qiannan senior high school chemistry teaching.The first part is the investigation of "evidence reasoning and model cognition" core literacy in Qiannan senior high school chemistry teaching.The Method of Core Literacy of Type Cognition.Investigation and analysis revealed that:1.Present situation of core accomplishment cultivation of "evidence reasoning and model cognition" in high school chemistry teaching in Qiannan prefecture is general.2.The application of "evidence reasoning and model cognition" in teachers' teaching is moderate,and the application in students' learning process is moderate.3.Most chemistry teachers do not attach importance to the cultivation of the core literacy of "evidence reasoning and model cognition" in classroom teaching.4.In the actual teaching process,teachers are not good at guiding students to assume,guess and verify problems.The main results of teaching practice research are:1.Classroom teaching based on "evidence reasoning and model cognition" is more helpful for students to learn and accept new knowledge.2.The cultivation of "evidence reasoning and model cognition" core accomplishment can improve students' academic achievement.3.The cultivation of "evidence reasoning and model cognition" core accomplishment can improve students' ability to solve problems.4.Pay attention to the experiment teaching in the teaching process,be good at guiding the students to model by simple and complex,which is helpful to strengthen the students' model thought and cultivate the students' consciousness of "evidence reasoning and model cognition ".In view of the problems existing in the cultivation of "evidence reasoning and model cognition" core literacy in Qiannan senior high school chemistry teaching,combined with the results of teaching practice research based on "evidence reasoning and model cognition ",this paper puts forward some suggestions for the cultivation of " evidence reasoning and model cognition " core literacy in Qiannan senior high school students.
