Research On High School Chemistry Concept Teaching Design Under The Concept Of In-depth Teaching

With the deepening reform of course teaching,training and development of the students is the core of quality education,the researchers focus on the core accomplishment of "cultivating people" the request,for "how to train people" provides the direction,but it itself cannot solve the problem of how to cultivate people,so the teachers in the teaching of how to develop and implement the core qualities are the hot topics in the study of many scholars.From the aspect of chemistry,it is necessary to cultivate and develop the students' core accomplishment of chemistry subject through high-quality chemistry classroom teaching.So what is a good chemistry class? Deep teaching guides the direction of quality classroom teaching.Teaching should not only stay in the formal surface learning,but also carry out profound and complete understanding of knowledge content,make knowledge logical and meaningful,cultivate students' higher-order thinking ability,promote students' development,and achieve the goal of education.Abstract and difficult to understand chemical conceptual knowledge,and numerous and confusing similar concepts are the difficulties for students to learn and understand.Therefore,this teaching content brings great difficulties and challenges to teachers,and it is also the knowledge point that always troubles students.In addition,the study of chemical concepts plays an important role in forming the core concepts of the subject,such as the concept of matter,the concept of elements,the concept of ions,the concept of transformation and the concept of conservation,which is conducive to the formation of students' chemical thinking and learning methods,and is the focus of teaching.Therefore,it is urgent to help students understand and construct concepts.Based on the background of the new curriculum reform,the author analyzes the value and feasibility of this study by combing relevant literature and then carries out a research on the concept teaching of chemistry in senior high school under the concept of in-depth teaching.First through the literature research to the problem,the research background,research significance,research content,etc,to understand the depth of deep learning,teaching and chemistry concept teaching research present situation,and on the depth of deep learning,teaching,chemistry concept for interpretation of the connotation of the concept related to determine the relevanttheoretical basis of this study.Then,on the basis of literature research,the present situation of chemistry concept deep teaching was analyzed by means of random survey of senior high school students and classroom observation and interview of four senior high school chemistry teachers,laying a foundation for the construction of high school chemistry concept teaching model under the concept of deep teaching.By selecting three typical cases "Amount of Substance","Ion reaction" and "REDOX reaction",the teaching design is carried out according to the teaching model,and the corresponding in-depth teaching case base is developed.After the comprehensive analysis of the above contents,some Suggestions for the deep teaching of chemical concepts are put forward:(1)Based on the new curriculum standard,teaching materials and the analysis of academic situation,the establishment of developmental teaching objectives;Create real problem situations to promote the formation of concepts;(3)Through experimental exploration and problem-driven,in-depth conceptual nature;(4)Based on thinking visualization,establish the connection between concepts;(5)Continuously pay attention to the evaluation method,and guide students to reflect deeply.In the end,reflection and summary are made in order to enrich the in-depth study of chemistry concept teaching and promote the implementation of the core accomplishment of chemistry discipline through this study.It is also hoped that this study can provide some valuable references for frontline chemistry teachers.
