The High School "chemical Balance" Teaching Design Based On The Core Literacy Of Chemistry

In the face of rapid economic development,rapid changes in technology,and changes in the participation of each of our citizens in social life,the application of knowledge innovation is particularly important.This requires the improvement of the overall quality of the people and the cultivation of qualified personnel.Education is an important way to cultivate talents,and China's education reform is constantly moving towards quality education.In 2014,the Ministry of Education proposed a core literacy system for students in each semester,which was refined into various disciplines and implemented in classroom teaching.The core literacy is a new challenge and requirement for teachers and students.Chemistry classroom teaching is an important carrier for students' core literacy training.Therefore,the relationship between teaching design orientation and core literacy is under the guidance of the new era education concept.Inevitability.The new definition of core literacy in chemistry and its new requirements for chemistry education make chemistry teaching design a dual task of cultivating scientists and improving citizen literacy.Therefore,the study of instructional design based on the core literacy of chemistry is of great significance.Study on the defines of core literacy,subject core literacy,core literacy of chemistry,teaching design,and balance concept by reviewing the literature and based on relevant theories.Explain the teaching design process based on the core literacy of chemistry.Conduct a practical study in a city A middle school(referred to as A middle school in the text).Through the questionnaire,the current situation of the teaching design of chemistry teachers in the school was analyzed.It was learned that although the teachers of A middle school were learning the teaching concept of the new curriculum standard,the teaching design of chemistry teachers mainly focused on completing the teaching tasks and could not fully understand the curriculum standards.The teaching objectives achieved in the classroom are of a single dimension,lacking students' independent inquiry,thus limiting the development of students' personality.The high school chemical equilibrium system includes: ionization equilibrium,precipitation and dissolution equilibrium,hydrolysis equilibrium,chemical equilibrium,etc.The chemical equilibrium occupies a central position in the equilibrium system.This study selects the human education version of the chemical elective four "Chemical Reaction Principles" in the second chapter of the third chapter.The chemical balance of the section is the research content,and the practical design of high school chemistry balance knowledge teac hing based on the core literacy of chemistry is considered,and the teaching design framework is constructed.Based on the analysis of the current situation of teacher teaching design,this paper finds the shortcomings of current chemistry classroom teaching design.Based on this,the high school "chemical balance" teaching design based on the core literacy of chemistry is carried out,and the teaching design is used in classroom teaching practice.Through the classroom observation,interviews and personal teaching reflection analysis,the advantages of the teaching design based on the chemicalbalance under the core literacy of the chemical discipline in the classroom teaching,students feedback on the new teaching methods.This thesis draws the following conclusions:(1)The teaching design classroom based on the core literacy of the chemistry subject is better,and students can ask questions and participate in the discussion better than the past chemistry classroom.The selection of instructional design goals requires a full understanding of the students' existing knowledge and abilities.(2)Learning chemical equilibrium movement with the help of a model is a very good chemistry learning method.The main goal in the past was to impart knowledge to students to acquire knowledge in the learning process of chemical modeling.In order to form a model,students had to open their brains;in order to prove the rationality of the model they built,students actively participated and cooperated Innovation,through exploring experiments,observing experimental phenomena,conducting macro-analysis,looking for evidence,bold reasoning,daring to question and argue,use this learning method to recognize,practice and use chemistry,thereby enhancing the core literacy of students in chemistry.(3)Not all classrooms are suitable for adopting an inquiry-based teaching model.Different courses have requirements for cultivating students with different abilities,requiring teachers to be good at thinking and gradually returning the main position of the classroom to students.It will be more conducive to the comprehensive development of students.
