Advantages of multiple-choice questions:
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. Multiple-choice questions are suitable for objective testing, because the form of multiple-choice questions does not require the teacher to grade the answers given, but only depends on the choice of the participants, so the possibility that the teacher is biased or partial to the students in the final score is greatly reduced.
Of course, if the questioner has not received relevant training, the topic may have subjective factors. In addition, the test paper should let the tester know clearly how to use the answer sheet or the check box of the online test to avoid misunderstanding.
