Concept:
Evaluation in education is categorized based on its timing and specific function.
• Formative Evaluation: Conducted during the instruction process to monitor and assess learning progress.
• Diagnostic Evaluation: Conducted to identify specific learning gaps, difficulties, or misconceptions that hinder a student's performance.
• Summative Evaluation: Conducted at the end of a course to certify achievement.
Step 1: Evaluating the Assertion.
While diagnostic evaluation is a form of assessment, its *specific* aim is not just to track "progress" but to uncover underlying causes of learning problems. Formative evaluation is the primary tool for assessing learning progress during a term. Thus, Assertion A is not correct.
Step 2: Evaluating the Reason.
The overarching and basic purpose of evaluation as a general educational tool is indeed to determine how much a student has learned and to assess their overall learning progress. Thus, Reason R is correct.
