Research On The Teaching Design Practice Of Atomic Structure Based On The History Of Chemistry

In the early 19 th century,Comte first discussed the connection between the history of science and education.The theory of history of science education has gradually become scientific and systematic with the development of the times.The history of chemistry belongs to the branch of the history of science.Making good use of the history of chemistry can promote the value of science education,and making good use of the history of chemistry can meet the ideological and political requirements of the curriculum.However,the study found that in actual teaching,the use of chemistry history resources is not good,and it is difficult for chemistry history to become a good material for middle school teaching design.In the teaching design of atomic structure,this research takes the characteristics of chemistry history resources as the basic starting point and follows the presentation logic of chemistry history materials as the basic follow to improve the teaching practice plan.Through the analysis of the students’ academic performance in the experimental class and the control class,the question of whether the teaching design based on the history of chemistry is better than the conventional teaching design is answered.This research follows the following research ideas: First,through literature analysis,combing the domestic and foreign research results of chemistry history education and teaching design,clarifying the significance and value of the atomic structure teaching content for high school chemistry learning,and starting from theoretical analysis Preliminarily draw up the program of instructional design,analyze each element of instructional design,combine with the purpose of this research to complete,and finally design a teaching plan suitable for this research;secondly,the analysis of each element of instructional design requires investigation to obtain Data,the preparation and distribution of the questionnaire,and the use of SPSS software to analyze the results of the questionnaire;finally,the teaching practice,through the analysis of the difference in the academic performance of the students in the experimental class and the control class,the results are based on the history of chemistry A comparative conclusion between the atomic structure instructional design and conventional instructional design.The results of this study show that the teaching design of atomic structure based on the history of chemistry is better than the conventional teaching design.The main reasons are: First,the teaching based on the history of chemistry helps students understand the nature of science,so that the process of learning knowledge is no longer superficial,and can understand the nature of the chemical changes of matter from the phenomenon,and enhance the logic and rigor of learning.Second,the teaching based on the history of chemistry can stimulate students’ interest in learning,and teachers can use the history of chemistry to make artistic transformations of the teaching content to make it more in line with the learning characteristics and psychological needs of students;third,the teaching based on the history of chemistry It can improve students’ academic performance.Teaching based on the history of chemistry can not only help students deepen the depth of knowledge understanding,but also help students expand the breadth of knowledge understanding.
