This method is generally suitable for simple topics that basically do not need "transformation" or reasoning. These topics mainly examine candidates' memory and understanding of physical recitation content, and belong to common sense knowledge topics. ?

Second, the comparative exclusion method-excluding dissidents?

On the basis of understanding the meaning of the question, this method first excludes obviously wrong or unreasonable alternative answers one by one according to the requirements of the question, and finally leaves only the correct answer. If the option is completely positive or negative.

Can be ruled out by giving counterexamples; If there are contradictory or mutually exclusive options between the options, one of the two options may be correct, and of course both options may be wrong, but they can never be both correct. ?

Third, the special value method and the extreme value method-opportunism?

It is difficult to directly judge whether the number of options is right or wrong, so some physical quantities can be tested one by one by taking special values or extreme values that meet the conditions of the topic. Any option that is proved to be incorrect by the test of special value or extreme value must be wrong and can be ruled out.

This method can often save strict logical reasoning or complicated mathematical proof.

If the questioner has received good training and the quality of the question can be guaranteed, then as a test item, multiple-choice questions are a very effective way. In addition, if students are taught the principle of multiple-choice form and their misunderstanding of multiple-choice questions is eliminated, their performance on multiple-choice questions will be better. Many evaluations have found that tests with multiple choice questions have higher reliability; Carefully screening the questions and paying attention to the special circumstances in the test will further improve the reliability.

When a large amount of materials are distributed in the survey, the multiple-choice survey method saves more time than the feedback survey that needs to be written. You can also use the software to use online survey to further improve efficiency.
