Research On The Chemistry Innovation Class Design In High School Based On Chemistry Discipline Core Literacy

With the rapid development of knowledge,economy and Internet,innovation ability has become the leading force and important source of national economic and social development,the cultivation of innovative talents has become a major strategy of national development.Core of cultivating the ability of innovation lies in the formation of innovative thinking,and innovative thinking cultivation is not built overnight,middle school students is the building of the country of the future,the youth still at the initial stage of life development,thinking bondage relatively less than adult,with the increasing of knowledge and experience of the increasingly rich,the cognitive framework existed in the mind will also gradually stereotyped and immobilized,built the formation of their own thinking habits,then weaken the innovation consciousness of teenagers and affect the development of innovation ability of teenagers.Therefore,the cultivation of innovative thinking and innovation ability in middle school teaching has become a crucial part of the cultivation of national innovative talents and even top-notch innovative talents,and the in-depth study of chemical innovation class has become a key step.This paper adopts mixed research method to investigate and study the chemistry innovation course.In the first part,the author makes visual analysis of literature on innovation courses in CNKI,conducts clustering analysis on keywords,and forms knowledge graph.Through the graph and data display,we can understand the status quo,hotspots,development trend and refine the meaning of innovation courses,class type and design steps of innovation courses.In the second part,designed the cognitive status quo of "chemical innovation class" questionnaire based on the literature analysis and theoretical study,making an online anonymous questionnaire survey through the middle school chemistry teacher,chemical research staff and normal chemistry student,trying to get cognitive status and implementation suggestions of the chemistry innovation course in chemistry education study group.In the third part,high school chemistry innovation course case analysis and case study design based on chemical subject core literacy will be implemented on a specific subject matter,depth excavation on subject original questions and design the teaching parts and teaching tasks based on the content of the subject matter of the curriculum standard and discipline knowledge structure,inspiring students' innovation consciousness from the perspective of subject principle.Designing the specific subject content from five aspects including literacy knowledge,discipline knowledge,interesting knowledge,strategies knowledge and evaluation knowledge based on PCK theory,cultivating students' innovative ability from various angles in the teaching activities.Constructing the chemical innovative teaching design model,"Galvanic cell" and "Ionic bond" teaching design were developed to provide reference for chemistry teachers trying to carry out innovative courses.Through the above research,the following conclusions can be drawn :(1)innovation course is a teaching concept based on the cultivation of students' innovative thinking and innovative ability.It emphasizes the guidance of problems,gives full play to students' initiative,and enables students to create new knowledge and improve their core qualities in learning.When making innovative class teaching design,teachers should take the core literacy of chemistry discipline as the cornerstone and carry out the design from multiple angles centering on the subject essence.(2)Chemistry teachers believe that innovation course is beneficial to cultivating innovative talents,which is of great significance.However,the practice of innovation course is limited by factors such as teachers' own level and teaching conditions.Therefore,it is suggested to actively carry out teacher training and teaching research activities of innovation course.(3)Through the case analysis and theoretical research of the innovation course,the teaching design model of the innovation course is put forward,and the teaching case of the chemistry innovation course based on the core accomplishment of chemistry discipline is developed,which makes a preliminary exploration for the further research and practice of the innovation course.
