Research On Chemical Teaching Design And Practice Of Chemistry History For Real Situations

"Ordinary High School Chemistry Curriculum Standard(2017 version of2020 revision)" focus on real situations,driving and utilizing chemical knowledge as tools to solve problems based on real situations.In the specific implementation of the cultivation of the core literacy requirements of student chemical disciplines,it is an effective way to create a practical situation in chemistry teaching.Enable students to intuitively feel the existence of knowledge in real learning situations,better-understanding knowledge.As an annual high school entrance examination,high school chemical electrochemical chemical content is widely complicated,and students often have something to make.It is worth mentioning that these fans are similar to the scientists’ mistakes in the development of electrochemical development.Therefore,this study tried to start the electrochemical content of different periods in the real situation in this study.Through the true problem,focus on the origin and definition of the relevant concepts,thus deepening students about the understanding of high school chemistry "electrochemical" content,transforming students’ cognitive methods,and promoting the scientific essence of students.In this regard,I try to complete electrochemical teaching designs based on chemistry history for real situations and applied in practical teaching.The specific research content is as follows:First,from the importance of core literacy,effective ways,and high school chemistry "electrochemical" teaching content,the topic background is elaborated;based on the status quo,chemical history classroom infiltration,chemical history classroom infiltration,chemical history integration real situation teaching status,the feasibility of research themes and define the concept of research;After the student questionnaire and teachers’ interview,I realized that the current history of chemistry teaching in high school teaching:students are more interested in chemistry history in class,and teachers also recognize the education function of chemistry history.However,in actual teaching,chemistry history only plays a simple important role,and it has not been fused with the real situation.Based on the above survey results and the suggestion of the class standard,the teaching design framework with chemistry history is the real situation,and the "chemical power","metal corrosion" and "metal protection" are carried out,and the actual teaching practice is carried out.Finally,in conjunction with students’ test scores and analysis of students and teachers,it explores practical teaching results.The results show that the experimental class has improved after chemistry history learning,proving that chemistry teaching is operability with chemistry history for real situations,which can effectively improve teaching quality and implement contemporary education objectives;At the same time,based on the teaching design of chemistry history for the real situation,the target requirements of the curriculum standard are added,improve the subjective status of students ’learning,promote the development of core literacy,etc.of students’ evidence and scientific attitude,promote the development of classroom teaching evaluation.
