The Research On The Learning Advanced Construction Of Elemental Compound Of Learning Based On Core Literacy

"Advanced learning" is also called learning process.The purpose of advanced learning is to change the trivial and lacking knowledge content in the courses studied.Its research results provide the basis for formulating curriculum standards,editing textbooks,designing teaching cases,teaching evaluation,and independent construction of student cognitive systems.This article takes "elemental compounds" as the research object,and elaborates its current research status through literature research methods.Through text analysis,it analyzes the students' knowledge of elemental compounds,and finds that the lack of progressiveness in the teaching of elemental compound knowledge leads to learning.Difficult question.Then systematically analyze the new curriculum standards and new textbooks,and on this basis,put forward the assumption of an advanced framework for elementary compound knowledge learning based on core literacy,and then use the content analysis of the new textbook human education version of elemental compound knowledge as a carrier through case analysis The design of the instruction finally confirmed the feasibility of the advanced framework for elementary compound knowledge learning,and provided part of the practical basis for the development of advanced learning theory.The advanced learning framework is "point-line-surface" three-level advanced as follows:Level 1(point): Understand the macroscopic composition of general substances.You can summarize and classify general substances based on elemental composition,and grasp the general substance.Preparation and use,and can know the objective existence of elements in the form of molecules,atoms,ions,etc.,and then cultivate students' macro-discrimination and micro-analysis combined literacy.Second level(line): It can classify and summarize the generality of various substances(metal simplex,nonmetal simplex,metal oxide,nonmetal oxide,acid and alkali salt,etc.).According to the microscopic composition and structure of the substance,Combined with the learning of redox reactions,galvanic cells,etc.to judge the properties of substances and the conversion between various substances,a general rule of "different positions and different properties" is summarized and students' scientific inquiry awareness is cultivated.Level 3(surface): Through the study of the periodic law of elements,the properties and uses of various substances(metals,non-metal simple elements,metal oxides,non-metal oxides,acid-base salts,etc.)can be deduced."Sex" and "bit-sex-path" recognize matter,and then have a complete understanding of elemental compound knowledge,improve students 'ability to solve complex problems,and cultivate students' scientific spirit.The teaching case designed with this framework was implemented in Liaocheng No.4Middle School and achieved good teaching feedback.The proposal of this framework helps to improve the teaching effect of elementary compound knowledge under the new curriculum reform concept;on the other hand,it helps to cultivate the subject literacy,speech literacy and network literacy of contemporary middle school students;it can also improve the teacher's teaching ability Design awareness.
