The Effect Of Chemistry Experiment Teaching Method On High School Students' Scientific Inquiry Ability

Chemical experiment is an important part of chemistry teaching and it is an important content of college entrance examination.One of the main reasons for the analysis of the the chemical college entrance examination paper in the past five years is that students' scientific inquiry ability is too poor.At present,the experimental teaching of high school mainly includes three kinds of conventional methods:virtual experiment,demonstration experiment and quiz experiment.There are few reports on the effects of the three experimental teaching methods on high school students' scientific inquiry ability,and the research is not deep.Therefore,this dissertation focuses on the effects of three experimental teaching methods on senior high school students' scientific inquiry ability,and has a positive guiding significance for teachers how to design courses.This thesis firstly designed the "Questionnaires for Asking and Assuming Ability of Senior High School Students" Questionnaire,and combined the English GCSE curriculum assignment with the original question and the self-education time training to carry out chemistry for students in two or three parallel classes in one middle school.The investigation of the five abilities of asking questions,conjectures and assumptions,gathering information,interpreting information,writing and communication in scientific inquiry capabilities.Subsequently,after randomly assigning the three experimental teaching methods to the three classes for a semester teaching practice,the following research conclusions were obtained through data collection,data collation,data statistics,and data analysis of the pre-and post-review questionnaires and survey research operations.1.All three presentation methods are conducive to the development of scientific inquiry capabilities.2.The quiz experiment has a greater improvement in the ability to raise questions and conjectures and assumptions in the scientific inquiry ability than the other two experimental teaching methods.3.The best representation method of electrochemical knowledge is the quiz experiment.Danger,experimental phenomena are not easy to observe,microcosmic changes,environmental pollution and high experimental costs.The best experimental presentation method is virtual experiment teaching method,but the combination of demonstration experiment teaching method is better.
