Research And Design Of High School Chemistry Experiment Operation Qualification Test Questions

Analysis of the 2018 Hainan High School Chemistry Qualification Test Operational Test Questions,Scoring Criteria and Examination Process Results found that in order to facilitate the one-on-one scoring and shorten the examination time of the examination organization and the invigilator,the test questions and scoring standards can only be simplified.Although the examination organization form seems to be very standardized,the examination results cannot objectively evaluate the students’ practical ability.In the implementation process,the experimental operation has not been truly valued,and the coping ability is obvious.Return to the core literacy training of the new curriculum standards,re-examine the position of experimental operation skills in science literacy training,and consider how scientific and objective measurement of high school chemistry experiment operation skills.On the basis of this,through the evaluation of the 2018 Hainan High School Chemistry Qualification Test and the scoring standards,the evaluation of the process and results of the test operation of a middle school experimental test,combined with the author’s observation and thinking of the invigilator in the invigilation process,The nine must-test test questions and scoring criteria for the academic qualification exams required in the new curriculum standards are designed.Applying the design questions and scoring standards to the one-to-one invigilation simulation test,it is found that the evaluation of students is more scientific and objective than the test questions and scoring standards currently used in Hainan Province,and it can reflect the actual level of students’ actual chemical experiments..The new test questions and scoring standards should be able to exert their advantages under the conditions of one-on-one proctoring and the invigilators have always maintained the best proctored state.According to the current conditions of the secondary schools,it is almost impossible to fully realize this.In order to solve the problem that the new test questions and scoring standards are not applicable to the manual proctoring,the experiment operation evaluation mode of “video recording and post-grading” researched by another student of the research group is used to evaluate the experiment by “preparing the concentration solution of certain substances”.A new model test was conducted for a student and it was found that the score in this mode is very close to the one-on-one census score.This shows that as long as the "video recording,post-grading" evaluation mode is adopted,the new test questions and research standards can continue to be effective.The artificial proctoring test limits the experimental operation test questions and scoring standards,so that the development and measurement of the experimental operation skills cannot break through the bottleneck.Outlook Internet technology and cloud data storage can be fully applied to the experimental operation test,creating feasible conditions for improving the quality of the test questions and scoring standards,standardizing and stabilizing the experimental operation test process,and evaluating the students’ experiments objectively,fairly and fairly.Operational skills lay the foundation for the inclusion of experimental results in the total score of the college entrance examination.
