Based On Key Competences Scaffolding Instruction For The Applied Research In Middle School Chemistry

Scaffolding Instruction is not only a kind of teaching thought of "scaffolding" is also a kind of teaching mode,which is based on the theory of the zone of proximal development put forward a kind of take the student as the main body,based on the student's own knowledge level,to cultivate students' problem solving ability,independent learning ability and innovation ability as the goal of teaching.Put forward in the 2017 revision of the ordinary high school curriculum standards of chemistry subject core literacy is "the identification of macro and micro analysis","the ideas of changes and balance","evidence reasoning and model recognition","scientific inquiry and innovation consciousness","scientific spirit and social responsibility".High school chemistry is designed to enable students to form the core qualities of chemistry that future citizens should possess,and to cultivate people with all-round development."Scaffolding" teaching can be used as one of effective teaching methods to realize the core quality of chemistry.Based on a large number of literatures,this paper analyzed the characteristics of "scaffolding" teaching,to determine the "scaffolding" teaching design principle,type,link,Sue includes and take 5,for example,finished the project three "unit 2 in common hydrocarbon of aromatic hydrocarbon" scaffolding "teaching design,and has carried on the teaching practice.By comparing the experimental classes and that in comparative classes and questionnaire,the following conclusions:(1)Scaffolding instruction can help students to better understand the knowledge and enhance their understanding of knowledge,which can help to improve the finishing speed and quality of homework and the monthly test results.(2)The survey shows that most students are interested in the way of "scaffolding" teaching,and can actively participate in the classroom study,and also set up the learning confidence.(3)the teacher interview found that use "scaffolding" teaching classroom atmosphere active,student participation is high,the teacher to student's evaluation of diversification,but at the same time,the teacher needs to spend more time preparing,class also need to spend more time and energy to focus on the students' cognitive development state.To sum up,"scaffolding" teaching mode is applied to chemistry teaching :(1)To highlight the guidance of learning methods,to impart knowledge and to impart learning methods,can help students to improve their learning methods.(2)It emphasizes the cultivation of students' core qualities in the course of teaching,and combining with the specific core knowledge teaching can help to bring the cultivation of students' core qualities into practice...
