Research On The Practice Of Scaffolding Instruction In Senior High School Chemistry Experiment Teaching

Chemistry is based on the experiments,learning chemistry experiment is conductive to cultivate innovative consciousness,practicing ability and other advantages of students,however,there are many disadvantages in teaching high school chemistry experiment,such as ignoring students' subjectivity,and the form in evaluation of students is single.In this literature,less studies on the application of scaffolding instruction in teaching chemistry experiment.To improve the problems of teaching high school chemistry experiment in the class,play the role in experiment teaching greatly,and meet the requirements of the new curriculum reform,we will combine the chemical experiment teaching and scaffolding instruction pattern,design cases and apply to the practical teaching,enrich the theory of scaffolding instruction pattern.In the teaching process of scaffolding,the workload of teachers is large,because teachers need to prepare multiple scaffolds for different students due to the differences in individual learning level and ability.In order to solve this problem,we increase the learning sheet of before and after class,it is based on the original five links.The addition of learning sheets can make students take class with questions,stimulate students' thirst for knowledge,shrink the gap of students in different levels,it is beneficial to achieve teaching's goal that "do not teach what students do ",improve the class efficiency,conducive to the students to consolidate after class.We intersperse the effect-evaluation of teaching pattern scaffolding in the after-school studying sheet,teaching process,case reflection,questionnaire and interview.This paper discusses the research status of scaffolding teaching theory,the concept of scaffolding teaching and its theoretical basis.To choose experimental classes and classes in comparative,design the interview outline,questionnaire and test paper(including before and after the test),to combine theory with practice,and apply to the design of the experimental teaching with the scaffolding instruction pattern,it is including three instructional design-the reaction of metal and nonmetal,sodium compounds and ammonia.Through practice and data analysis,this paper demonstrates the feasibility of application of scaffolding instruction in chemical experiment teaching pattern,the application of scaffolding instruction pattern enhances the charm of chemistry,it is beneficial to arouse students' interest,improve class effect,enhance the student test scores.It is conductive to cultivate students' good study habits,students' learning attitude,to cultivate the abilities of students' operating,exploring consciousness,and to cultivate the students' competitive consciousness.Otherwise,collaborative learning is beneficial to cultivate the students' language power of expression,promote the emotional communication between students.Scaffolding teaching pattern embodies the teaching idea that student as the main body,teacher as the leading factor.The student as the main body,students' divergent thinking can create many ideas,this requires the teacher must have a lot of knowledge accumulation,so teachers should strengthen their own self-cultivation.
