Research On High School Chemistry Teaching Strategy Based On Effective Cultivation Of Students' Evidence Reasoning And Model Cognition

With the promulgation of the 2017 edition of the new curriculum standards,the following are proposed: Put forward that core literacy of high school chemistry discipline is an important part of high school students to develop the core quality,is the embodiment of students' comprehensive quality Chemical in this subject has a very important role in the national life Therefore,how to develop the core of the chemistry subject accomplishment,become the primary task of the current education reform One of the five dimensions of evidence reasoning and model recognition Chemical core literacy has become the core of thinking on how to effectively train students in the teaching of the core literacy has become the hot topics in the study of the general education scholars By consulting a large number of data found that how to effectively cultivate students core literacy research is more,but on how to effectively develop the students' ability of evidence reasoning and model recognition is very few research.By reading a large number of literature in this article the research background of chemical science literacy of the new curriculum reform in China are put forward for high school students core literacy requirement and evidence reasoning and model recognition in the teaching occupies the proportion of the domestic and foreign research present situation analysis,put forward in this paper,the research content and the general train of thought According to the new course standard of related concepts The theoretical basis is defined and the level requirements of evidence reasoning and model cognition are put forward.Questionnaire survey and teacher interview are conducted on the representative students selected from Qinggang No.6 Middle School.SPSS is used for questionnaire analysisThrough the analysis of the questionnaire survey and interview results,the following conclusions are drawn: most students have strong interest in chemistry learning,moderate ability of independent learning habits,and weak understanding of evidence reasoning and model cognition,so they cannot bring the awareness of evidence reasoning and model cognition into the course learning Teachers' understanding of evidence reasoning and model cognition only exists on the surface,but there are many ways to learn and are in continuous progress,and are gradually bringing the cultivation of evidence reasoning and model cognition into the classroomAccording to the survey results,according to the new curriculum standards,meaningful learning theory and lifelong learning theory,the cultivation strategy of students' core literacy of "evidence reasoning and model cognition" in chemistry teaching is explored.It is necessary to improve the training mechanism,optimize teachers' literacy level,pay attention to gradual infiltration in teaching and introduce a complete feedback system.In the classroom,we should start from five aspects,namely:setting up problem scenarios and guiding students to predict;Provide sufficient evidence for reasonable analysis;Carry out experimental research and scientific demonstration;Ask questions and feedback in time to promote thinking progress;Excavate the contents of teaching materials and construct cognitive models.In addition,the author conducts case teaching of "Periodic Law of Elements" and "Primary Battery" in the textbook,and summarizes and reflects on it.Because of my limited ability,the method in this paper is only a preliminary exploration,and more chemistry teachers are needed to join in the research and constantly improve the results,so as to achieve the goal of all-round development of middle school students in chemistry teaching.
