How should an instructor assess prior knowledge of students?

Assessing prior knowledge of students is critical in tailoring instruction to meet their needs. Using pre-assessments, surveys, or informal discussions allows the instructor to gain valuable insights into what students already understand and what gaps may exist in their knowledge.

Pre-assessments are designed to evaluate the existing knowledge base of students before the instruction begins, ensuring that lessons can be appropriately adjusted. Surveys can gather specific data on students’ backgrounds and experiences related to the subject matter, while informal discussions promote an open exchange where students can express their thoughts and understanding of the topic.

Relying solely on previous test scores might not provide a complete view of what students currently know or remember, as test scores can reflect only a snapshot of performance rather than a comprehensive understanding. Checking attendance does not offer any information regarding students' preparedness or comprehension of the material, and assigning a homework questionnaire may not engage students sufficiently to elicit honest or comprehensive feedback on their prior knowledge.
