Investigation And Study Of High School Students' Imagination Thinking In The Module Study Of "The Principle Of Chemical Reaction"

The learning of the "Chemical Reaction Principles" module has an irreplaceable role in deepening the understanding of chemical reactions.It can enable students to understand chemical reactions from static to dynamic,from qualitative to quantitative,and from macro to microscopic development.The 2017 edition of the "General Senior High School Chemistry Curriculum Standard" pointed out that the core literacy of the chemical discipline includes five aspects,one of which is evidence reasoning and model cognition,which coincides with the connotation of deductive imaginative thinking and theoretical model imaginative thinking.Most of the chemical reaction principles are abstract and general.When students study,they need to imagine the construction of models and scenes.This can make it easy to understand the principle of chemical reaction.In this paper,four research problems are formed based on the imaginary thinking in the study of the "Chemical Reaction Principle" module:(1)Analyze the components of imaginary thinking in the "Principles of Chemical Reaction" module and related content of the college entrance examination questions;(2)To understand the situation of high school students' imaginary thinking in the study of the "Chemical Reaction Principle" module;(3)Analyze the problems existing in the cultivation and application of imaginary thinking in the study of the "Chemical Reaction Principles" module of high school students;(4)Put forward some targeted suggestions for the cultivation and application of high school students 'imaginary thinking in the study of the "Chemical Reaction Principles" module.This paper takes the investigation as the main method,this paper investigates the situation of high school students 'imaginary thinking in the study of the "Chemical Reaction Principles" module.The investigation shows that:(1)It can be seen from the students' memories of the course that teachers have a certain sense of cultivation of deductive imaginative thinking,but due to various factors,there are many difficulties in practice;(2)In the field of theoretical model thinking in chemical reaction and energy,students have certain model thinking,but few at higher level;(3)Most students can imagine a certain number ofmodels in terms of chemical reaction rate and theoretical thinking in chemical equilibrium,but it is difficult to construct a complete and correct model thinking;(4)In the theoretical model thinking of ion balance in aqueous solution,most students can also have a certain level of model thinking,but the overall level of imaginary thinking is low;(5)In the field of theoretical model thinking based on electrochemical theory,most students can also imagine thinking in a certain way,but the overall state of thinking is in the middle and low level.In view of the problems found in the investigation,the author puts forward the corresponding suggestions to the teachers:(1)To cultivate the students 'consciousness of thinking in chemical imagination;(2)To improve its own knowledge system and improve its own level of imaginative thinking;(3)To pay attention to the design of teaching activities and assignments to foster students 'imagination;(4)Application of micro-simulation based on information technology to teaching.Put forward the corresponding suggestion to the student:(1)Pay attention to perfect the knowledge system,avoid the myth in the process of forming the imaginary thinking;(2)Be diligent in thinking,divergent in thinking,and relate to what you see and hear everyday;(3)The cultivation of speculative thinking should pay attention to the strictness.
