Research On The Development Of Middle School Students' "Macro Identification And Micro Analysis" Key Competency

Key competency has become the focus of basic education reform and research all over the world.Chemistry is an important branch of basic education,and the key competency of chemistry is also the focus of research by educational experts and scholars from all over the world.In China's High School Chemistry Curriculum Standards issued in 2017,the key chemistry competency is divided into five dimensions,and the content and level requirements of each dimension are elaborated in detail.Among them,"macro identification and micro analysis" is the most characteristic dimension of chemistry discipline,and the development of this dimension determines students' understanding of chemistry discipline.So the research on students' key competency of "macro identification and micro analysis" has important theoretical and teaching significance.Through to the identification of "key competency","macro and micro analysis of the literature reading and analysis" in recent years,the author found that although the chemical experts and scholars to the chemical disciplines key competency awareness rising,but they are mainly for key competency connotation,composition and implementation strategy of theoretical research and concrete teaching case study,the lack of evaluation methods of research,put forward the strategy of the lack of maneuverability,cannot provide scientific and effective guidance to the practical teaching.Because there has not yet been a junior high school chemistry curriculum based on core literacy,most of the research is based on the key competency of senior high school students,while the research on the key competency of junior high school students is relatively weak.This article through the theoretical reference and concept definition,to a 2017 edition of "the ordinary high school chemistry curriculum standard",2011 edition of"compulsory education chemistry curriculum standard",grade nine junior middle school chemistry teaching material as the theoretical basis,combined with the examination questions and junior high school students' psychological characteristics,build the junior middle school students' identification of macro and micro analysis "key competency framework,compiled a good reliability and validity of testing tools,and implementation of the graduates in ninth grade measurement,data collection and analysis,to understand the development of the dimension of the core qualities in junior high school students.Finally,according to the weak problem of students' key competency of "macro identification and micro analysis",the author combined with the specific examples of his own teaching experience to put forward more effective training strategies,in order to provide some reference for the teaching of front-line teachers.
