What is the multiple selectivity problem?

Multiple-choice questions are a common type of questions, which are widely used in educational examinations, academic examinations, recruitment examinations and other fields.

This is a method to test subjects' choices or answers to specific questions. In multiple-choice questions, a question or statement is usually given and multiple alternative answers are provided, from which the subjects need to choose one or more answers as the answers.

Characteristics of multiple selectivity problems:

1. Alternative answers: Questions are usually accompanied by multiple alternative answers, including correct answers and interference answers (wrong options).

2. Single choice and multiple choice: Multiple choice questions are divided into two forms: single choice and multiple choice. Multiple choice questions require the subjects to choose a correct answer from the alternative answers; Multiple-choice questions allow subjects to choose more than one correct answer, but they may also be deducted or not given points at all.

3. Time limit: In exams or tests, multiple-choice questions usually have a time limit, and the subjects are required to answer within the specified time.

Advantages of multiple-choice questions:

1. Efficient evaluation: multiple-choice questions can effectively evaluate the knowledge and understanding of the subjects, and are suitable for large-scale examinations and tests.

2. Objective scoring: The scoring of multiple-choice questions is relatively objective, which reduces the possible deviation caused by subjective scoring.

3. Wide coverage: it can cover a wide range of knowledge and examine different levels of understanding and analysis ability.

4. Timely feedback: Multiple-choice questions can usually be answered quickly, and immediate feedback is provided to help subjects understand their mastery.

Multiple-choice questions are usually used in combination with other questions to comprehensively examine the knowledge and ability of the subjects. At the same time, the questioner should also pay attention to designing reasonable questions and alternative answers to ensure the scientificity and credibility of the questions, so as to effectively evaluate the academic performance and ability level of the subjects.
