If used exclusively, which of the following types of questions tends to encourage students to guess?

The type of question that tends to encourage students to guess when used exclusively is the yes or no question. This is because these questions often present binary choices, making it easier for students to make random guesses without a deep understanding of the material. The simplicity of having only two possible responses does not demand critical thinking or elaboration, which can lead to a higher tendency for guesses.

When students face yes or no questions, especially if they're unsure or lacking confidence in the subject matter, they might opt for one of the two answers without sufficient justification. This reliance on chance can detract from the learning process and does not promote a comprehensive grasp of the instructional content.

In contrast, other question types, such as true or false or short answer, generally require more engagement and thought, prompting students to reflect on their understanding before providing an answer. Consequently, while yes or no questions may serve certain purposes in assessment, relying on them exclusively can lead to a guessing culture rather than an informed decision-making process.
