Recitation contain relevant definitions,theorems,ideas and methods of the knowledge learnt by students.They are the links that students use to communicate theory and practice.In high school chemistry teaching,it is an important teaching method to consolidate teaching results and guide students’ learning direction through exercises.In January 2018,the Ministry of Education promulgated “the Standards of Chemistry Curriculum for Senior High Schools(2017 edition)”,which clearly put forward the fivedimensional core literacy of chemistry discipline and put forward different implementation suggestions for each stage of teaching content.In the "Teaching and Evaluation Recommendations" of the general implementation proposal,it is stated that teachers should pay attention to the diagnostic and developmental functions of classroom exercises for s students’ core qualities of chemistry,and carefully compile or select classroom exercises according to the academic requirements of each subject in the course content,so as to effectively promote the formation and development of students’ core qualities of chemistry.Therefore,it has important teaching significance to implement the core literacy of chemistry subject into senior high school chemistry exercises class.It can not only lay the foundation for my future teaching work,but also provide reference for other chemistry teachers.The main research methods of this study are literature research,interview and action research.Firstly,research the domestic and foreign literature on "core literacy" and "discipline core literacy" to understand their theoretical connotation and development process.On this basis,the interview survey of the teachers in the practice school was conducted to find out the deficiencies in the cultivation of core qualities in the chemistry recitation.Then,according to the survey results and the students’ learning situation and psychological characteristics,guided by the core quality of chemistry subject,the teaching principles and strategies of senior high school chemistry exercises are put forward in the two stages of "teaching content preparation" and "classroom link design" :1.Preparatory stage of teaching content: Analyze academic requirements of knowledge and reasonably set teaching objectives;Analyze the college entrance examination papers in recent years and grasp the presentation of exercises;Carefully select teaching content in combination with core discipline literacy.2.Design stage of teaching link: Attach importance to creating exercise situations to stimulate students’interest in learning;Pay attention to strengthening cooperation and communication to highlight students’standard;Follow the psychological rules of students and select teaching methods.Finally,following the above teaching strategies,the author takes "sodium and copper sulfate reaction" and "chemical balance image" as examples,designs chemistry exercises teaching program in senior high school,which highlights students’ principal position and effectively cultivates students’ core literacy of chemistry.These instructional designs have been applied to practical teaching and good feedback has been obtained. |
