Teaching Research On Inorganic Compounds Based On Macroscopic Identification And Micro-Exploration

Education,science and technology,and talent are the basic and strategic supports for the comprehensive construction of a modern socialist country,which is emphasized in the report of the 20 th National Congress of the Communist Party of China.Chemistry,an important part of natural sciences,is closely related to social development.The students need to transform chemical knowledge into core literacy to meet the requirement of the education of chemistry.In high school chemistry teaching,the key to the development of students’ core literacy in chemistry is cultivating students’ triple representation thinking of “macro-micro-symbolic” The knowledge of inorganic compounds in the compulsory courses of high school chemistry is the basic content of high school chemistry,which is also an important content carrier for cultivating students’ macro identification and micro exploration literacy.Hence,it is particularly important to carry out the study of the teaching and research of inorganic compounds based on the macro identification and microanalysis for promoting the formation of students’ core chemical literacy.This thesis starts with the cultivation of students’ core literacy of macro identification and micro exploration.In addition,the research status of macro-micro integration at home and abroad has been understood through a literature review,the core concepts have been defined based on research theory,and the current situation of teacher-teaching and student-learning has been understood through the use of questionnaires,and the problems existing in the current teaching process have been discovered.On this basis,the characteristics of inorganic compound knowledge have been analyzed,and the teaching procedures and strategies of inorganic compound knowledge of macroscopic identification and microscopic exploration have been constructed.Moreover,the teaching practices have been carried out,and the teaching practice effects are:(1)improving students’ academic performance;(2)increasing students’ motivation to study chemistry;(3)enhancing students’ ability to recognize the knowledge of inorganic compounds;(4)and improving the students’ macro identification and micro exploration literacy.The thesis contains four parts:Part Ⅰ: Discussion of the background,purpose,and significance of the research,and confirm the research content.Part Ⅱ: Arrangement of relevant literature,the definition of core concepts,and clear the theoretical basis of research.Part Ⅲ: Performing in practical teaching to find out the problems in current chemistry teaching.Part Ⅳ: Analyzed the knowledge characteristics of inorganic compounds,understood the formation process of macroscopic identification and microscopic exploration,constructed teaching procedures,proposed teaching strategies,formulated teaching plans and practices,and analyzed teaching effects.Conclusions have been made by theoretical and practical research on teaching inorganic compound knowledge based on macro identification and microanalysis,which is shown as follows:(1)the teaching methods such as problem context creation and experimental inquiry could effectively stimulate learning interest;(2)the teaching strategy of cultivating students’ macro-micro literacy in the teaching process of inorganic compounds was implementable;(3)Pay attention to the cultivation of macro and micro thinking,and independently used the combination of macro and micro chemical thinking to solve problems.
