Study On Deep Learning Of Chemistry Concept Of High School Students

In February 2019,the CPC Central Committee and the State Council issued the "China Education Modernization 2035",which emphasizes that in order to realize the modernization of education,it is necessary to speed up educational reform in the information Age and promote educational modernization with informationization.In this age of informationization,the presentation of deep learning is an active response to the challenges of the Times.As an important measure of contemporary learning science,deep learning is an objective requirement for the development of information society,a natural product of learning scientific development,or an inevitable choice for curriculum teaching reform to advance in depth.At this stage,the study of deep learning has begun to be implemented in various disciplines,research and application of deep learning in chemistry,especially in chemical concepts are relatively rare.And the chemical concept is the foundation and core of chemical knowledge,students for its study is to achieve the understanding,mastery,use and evaluation of higher levels of competence,which coincides with the characteristics of deep learning,so to promote the deep learning of students ' chemical concepts is of great significance.The main points in this graduate thesis are as follows:The first part discusses the domestic and international background of the research,combs the research on chemical concepts and deep learning,and expounds some of the research results.The second part defines the connotation of "deep learning" and "chemical Concept",describes their characteristics,and distinguishes the characteristics of deep learning and shallow learning based on "Three fields six dimensions".This paper expounds the theoretical basis of deep learning.In addition,the relationship between deep learning and chemical concepts is expounded,the Deep Learning feature table of high school chemistry concept is constructed,and the level of deep learning of chemical concept is constructed by combining the goal classification of Bloom cognitive field.In the third part,the questionnaire of chemical concept in compulsory 1 of people's education Press is compiled,the teachers' identification of chemical concepts is investigated,the chemical concept in compulsory 1 is established,and 30 chemical concepts are selected.From the perspective of middle school chemistry education,the concept name and connotation of each chapter are established.At the same time,the understanding of "concept" and "chemical concept" of different teachers is also analyzed.In the fourth part,the questionnaire on the status quo of high school students' deep learning of chemical concepts was compiled,and the actual situation of students was investigated.In addition,from the "three dimensions and six dimensions",according to the problems set by different dimensions,the students' deep learning situation is analyzed.Finally,five factors,including classroom introduction,multimedia-assisted instruction,teacher evaluation,student learning status,and teacher-student relationship types,are analyzed to analyze the deep learning of students' chemical concepts.In the fifth part,the questionnaire of the influencing factors of high school students' deep learning of chemical concepts was compiled,and the actual situation of students was investigated.Based on the method of qualitative research,the students' answers are coded based on grounded theory,and the corresponding models are constructed.At the same time,the open decoding frequency of teaching factors that promote students' deep learning of chemistry concepts was analyzed and analyzed.In the sixth part,the deep learning process of high school chemistry concept is constructed.In the discussion of strategy,four strategies are proposed.Then,the course of deep learning of chemical concept is constructed,four steps of deep learning of chemical concept are established,and redox reaction is taken as an example to expound the teaching case of deep learning of chemistry concept in senior High school.
