What should Mr. Keller do to identify learning gaps among students based on exam results?

• A. Conduct one-on-one interviews with students
• B. Review the course syllabus with students
• C. Perform an item analysis on the semester exam
• D. Hold extra review sessions before the exam

Answer: (C)

Performing an item analysis on the semester exam is an effective way for Mr. Keller to identify learning gaps among students. This process involves a detailed examination of how students performed on each question of the exam. By analyzing which questions were answered incorrectly and identifying patterns, Mr. Keller can gain insights into specific content areas where students are struggling.

This approach allows him to determine whether the issues are related to misunderstandings of concepts, difficulties with problem-solving, or other factors affecting student performance. Consequently, targeted instructional strategies can then be developed to address these identified gaps, ultimately enhancing students' understanding and learning outcomes.

The other options, while potentially useful in different contexts, do not directly focus on assessing student understanding based on exam results. For example, one-on-one interviews can provide qualitative insights but may not offer the comprehensive data needed to pinpoint widespread learning gaps across a larger group. Reviewing the course syllabus is informative regarding expectations but does not assess students' comprehension or identify specific weaknesses. Holding extra review sessions might support students in their learning, but it does not itself diagnose the learning gaps based on exam performance.
