A third-grade teacher decides to have students rate their classmates as each one reads his or her report on an important person aloud. Which of the following sets of criteria is most appropriate to ask students to rate?

While using multiple sources is important for research assignments, it is not a critical criterion for evaluating a student's oral presentation. Third graders are still developing their research skills, and this criterion may not be age-appropriate or relevant to the immediate goal of assessing presentation delivery.

Although the use of varied vocabulary and smooth transitions enhances writing quality, the focus of this activity is on oral presentation. For third graders, the emphasis should be on how they communicate their report verbally rather than the complexity of their written language.

This criterion is relevant for written assignments but not for oral presentations. While students should be encouraged to use proper language mechanics in their written work, assessing spelling and punctuation does not apply when they are reading aloud, as the oral presentation primarily evaluates their speaking skills.
