Which of the following is an example of formative evaluation?

Formative evaluation refers to assessments conducted during the learning process to monitor progress and inform instruction. This type of evaluation helps educators and students understand where weaknesses exist and what areas need improvement, allowing for immediate feedback and adjustments.

Pretest quizzes serve this purpose effectively, as they can gauge students' prior knowledge and pinpoint specific concepts that require further review before moving on to more complex topics. By providing a snapshot of the learners’ understanding at a particular moment, pretest quizzes guide both teaching and learning.

In contrast, an IQ test typically measures intelligence at a single point in time without the objective of guiding further learning. The RD exam assesses the overall competence and knowledge of a registered dietitian upon completion of education, representing a summative evaluation rather than an ongoing assessment. Comparative evaluations involve comparing different groups or outcomes, which does not provide the instantaneous feedback or guidance characteristic of formative evaluations.
