Based On The Study Of The Core Accomplishments Of The Chemical Change Balance Ideology

The new edition of the “High School Chemistry Standards(2017 Edition)” gives the core accomplishments of chemistry and the corresponding connotation requirements,and puts forward the target of senior high school chemistry curriculum,according to the specific requirements of senior high school students' core accomplishments to adapt to their own development and social development.As an important part of the core accomplishments of the middle school students to meet the needs of social knowledge development,the core accomplishments of chemistry discipline plays a guiding role in the practice of discipline teaching activities.Among them,“change concept and balance thought” is one of the most representative parts that can reflect the chemical thinking cognition and discipline concept.It plays an indispensable role in realizing the core accomplishments of high school students in an all-round way.The research contents are presented below.Firstly,the author summarizes the research status of core accomplishments at home and abroad,the status quo of core accomplishments research in chemistry,and the current research level and progress of the literacy of “change concept and balance ideology”.Secondly,under the guidance of the literacy connotation,this paper puts forward different teaching modes combined with information technology teaching to improve the core accomplishments of students' change concept and balance ideology through the analysis of the knowledge points of “ion balance in solution”.Thirdly,in order to fully demonstrate the teaching effectiveness based on the concept of change and balanced core accomplishments to improve the effectiveness of students' core accomplishments through the "ion balance in aqueous solution" knowledge,three teaching designs are designed.Then,two parallel classes are selected to teach the actual data.Test data are collected and analyzed through software to obtain the teaching effect and the improvement of the core accomplishments of students are also inferred.Finally is the reflection summary,provides a reference for the chemistry discipline education work.
