The Practice Research Of Changing The Verification Experiment To Exploring Experiment In An Ethnic Minority Middle School

Inquiry teaching is the teaching method advocated by the new curriculum reform,and chemistry is a subject based on experiment.Therefore,exploratory teaching should be implemented and exploratory experiment will be the key.It is of great practical significance to change some confirmatory experiments into exploratory experiments.This thesis is divided into six parts:the first part is the introduction,which mainly explains the background and purpose of the research.The second part,literature review,Elaborates the core concept,the verification experiment,the exploratory experiment.The research status of exploratory experimental teaching in China and abroad is also studied.This paper points out the theoretical basis of exploratory experimental teaching.The third part,elaborates the preparation and implementation of questionnaire survey.In the fourth part,the author carries out a questionnaire survey on the current situation of the three ethnic minority middle school teachers,and finds out the influencing factors that restrict the implementation of exploratory experimental teaching.The fifth part,in view of the teachers inquiry-based experiment material sources,less proposed validation experiments to explore experimental strategy,try from the experimental principles,steps and phenomenon,conclusion and several aspects to improve the error.The sixth part,grade in Yu xi city national middle schools for a year exploratory experiment teaching practice,investigation and study exploratory experiment teaching to the student's academic performance,experimental operation ability,chemistry learning ability and the influence of teachers inquiry-based teaching idea change.The seventh part,conclusion and reflection,summarize and summarize the paper,summarize the research conclusion,analyze the innovation points and deficiencies.The conclusions of this paper are as follows:1.From the experiment principle,the operation steps,the phenomenon,the conclusion and the error aspects,it provides the idea and method to explore experiment design for minority chemistry teachers for changing the verification experiment of the textbook to the inquiry experiment.2.The implementation of inquiry-based experimental teaching in minority schools is conducive to improving students' academic performance in chemistry.3.The implementation of exploratory experimental teaching in minority schools is conducive to improving students' experimental operation ability.4.The implementation of inquiry-based experimental teaching can help to improve the chemistry experiment exploration ability of minority students.5.The implementation of inquiry-based experimental teaching helps minority middle school teachers to change their teaching concepts and to cultivate students'innovative consciousness in teaching.
