| In recent years,the National College Entrance Examination focuses on the students’ ability to learn and to solve practical problems based on real situation;This will not only examine the subject knowledge and subject competencies,but also develop students’ abilities in subject characteristics.The National College Entrance Examination is an important turning point for students to change their destiny and realize their ideals,and the chemistry study is the lubricant of this turning point.Therefore,it is significant to form and develop each student’s key competencies of chemistry.The “Chemistry Curriculum Standards for General High School”(2017 edition)points out that the way students develop the key competencies of chemistry is mainly based on teachers’ classroom teaching practice of competencies.This heavy duty,which developing students’ chemistry discipline key competencies,is mainly on the shoulders of first-line chemistry teachers,and puts higher requirements on the professional quality of chemistry teachers.After madding an integrated analysis of the National II Volume of recent years,we found that the score of the “the Principles of Chemical Reactions” module accounted for an important proportion.Therefore,it is particularly important to infiltrate the key competencies of chemistry in the teaching of this module.Knowledge is a central carrier in the development of competencies.In the process of students’ development,knowledge may be forgotten,but competencies can be left,so classroom teaching based on competencies is necessary.On the basis of reading a large amount of competencies,a basic literacy analysis of the knowledge involved in the “the Principles of Chemical Reactions” of the 2016-2018 College Entrance Examination in chemistry are conducted.At the same time,the specific relationship between the content requirements,the academic level requirements of the three themes in the new curriculum standard and chemical core literacy are also analyzed.Finally,the author constructs the teaching strategy,writes a teaching design based on literacy-based and applies it to the teaching practice.The main contents of this paper are as follows:The first part is "Introduction".From the importance of the key competencies development of chemistry disciplines,the author analyzes the relationship of the key competencies,the curriculum objectives and the instructional design in chemistry,also illustrates the importance of key competencies of chemistry content in the " Principles of Chemical Reactions" module of the College Entrance Examination.Finally,the research content,significance and main methods of key competencies of chemistry are described.The second part is “Overview of Domestic and Foreign Research”.By using the literature research method,the core literacy research status at home and abroad are summarized,related concepts are explained,and the main education theoretical basis are expounded.The third part is “The content analysis based on the key competencies of chemistry”.The key competencies of chemistry are introduced at the levels of the connotation and the competencies.At the same time,the knowledge of the “Principles of Chemical Reactions” of the National New Curriculum Standards for 2016-2018 is analyzed from basic literacy level.Moreover,the specific relationship between the three themes and the five aspects of competencies is analyzed,and competencies-based teaching strategy is constructed.The fourth part is “Teaching Design and Classroom Practice of the competencies-based Chemical Reaction Principles”.Based on the teaching practice of the competencies-based teaching design in the internship class,the results of the two classes before and after the experiment and questionnaires are analyzed.And the interviews with teachers are recorded.Finally,the teaching results are comprehensively evaluated.The fifth part is “Conclusion and Prospect”.According to the development trend of the key competencies in the chemistry classroom and the reform direction of the National College Entrance Examination,the author expounds his own views,and suggests improvements of the problems in the paper.Finally,gives hope to the development of key competencies in chemistry. |
