Research On Chemical Balance Teaching Based On Deep Learning

"Chemical equilibrium" is an important core concept in senior high school.Students' understanding of the concepts related to "chemical equilibrium" has an important influence on the study of ionization equilibrium,hydrolysis equilibrium,precipitation equilibrium and other equilibrium systems of water solutions in the elective part.And in the process of teaching practice,found that students in many cases,the understanding of the chemical equilibrium content level in shallow learning level,mechanically recited the relevant concepts and rules,a chemical equilibrium cannot be established,not to shift the relevant knowledge of chemical equilibrium is applied to the other balance system,is not conducive to develop students "the ideas of changes and balance" chemical core literacy.Therefore,teachers are in the process of teaching to stimulate students' learning status,help students to make a positive commitment to learning,guide students to understand the concept of chemical equilibrium,on the basis of the students to achieve deep learning level,to develop advanced thinking ability,able to apply knowledge of chemical equilibrium migration is applied,solve the problem of poor structure,establish the knowledge structure network independently.Were reviewed in this paper the " chemical equilibrium " and " deep learning ",on the basis of knowledge content,such as the guiding ideology on the theory of deep learning,summary the characteristics of chemical deep learning and deep learning chemistry concept teaching strategy,and combined with the content of the "chemical equilibrium" has carried on the detailed elaboration,analyzed of the chemistry course standard,teaching material about the content of the chemical balance,and then based on the deep learning design the teaching process of "chemical equilibrium",for inspection based on the deep learning teaching effect,the author has carried on the teaching practice research.Practice results show that understanding the concept of the experimental group is significantly higher than the control group,and the experimental phase heterogeneous want to significantly reduce the number,which is based on the concept change of teaching is good for students to participate on the depth of the knowledge of chemistry and deep learning,developing students'ability of higher-order thinking,form their own network structure of knowledge,cultivate the students'ideas of changes and balance"at the core of the quality.This paper mainly includes seven parts,the main contents are as follows:The first part,first of all,explained the reason of the topic.The second part,this paper summarizes the research on deep learning and chemical balance teaching at home and abroad,and finds out the research points of this paper by analyzing and summarizing on the basis of making clear its consensus and development trend.The third part is the purpose,task and method of the research.The forth part is the theoretical conception of the research.The characteristics of chemistry deep learning and the effective strategies of concept teaching are clarified,and the "chemical balance" is expounded in detail.The fifth part analyzes the teaching content.Firstly,this paper analyzes the contents of the standard of chemistry courses in ordinary senior high schools,and makes clear the importance of this course by connecting the requirements of compulsory and elective courses in junior high schools and senior high schools.Secondly,it analyzes the arrangement of textbook contents and related contents,so as to understand the difficulty of the course contents and determine the depth of teaching.Then,the students' understanding of the concept of chemical equilibrium is analyzed.At the same time,the analysis of the core objectives of chemical balance content is carried out to facilitate the cultivation of core qualities in teaching.Combining the contents of chemical equilibrium,the challenging task and driving problem are designed.The sixth part,teaching practice research.By means of the test question of "concept scale of chemical balance",the teaching effect was tested,and the data result of students' understanding level was analyzed by using SPSS and Rasch model.Meanwhile,the quantity of the development of students' core accomplishment and specific isomorphic thinking wasanalyzed.The seventh part,research conclusion and prospect.This paper summarizes the teaching effects of deep learning-based chemistry balance teaching in the aspects of understanding level,heterogeneous thinking transformation and core accomplishment improvement,and expounds the shortcomings in teaching research.
