Final answer:
Assessment for learning is formative, focused on feedback during learning, whereas assessment of learning is summative, evaluating mastery after instruction.
Step-by-step explanation:
The basic difference between assessment for learning and assessment of learning is that assessment for learning refers to formative assessments designed to provide feedback and guide student learning during the instructional process, while assessment of learning refers to summative assessments used to evaluate a student's mastery of course content at the end of an instructional period. Formative assessments like Grasp Checks and Check Your Understanding questions are meant to help students understand concepts as they are learning them. In contrast, summative assessments such as Performance Tasks are more comprehensive and measure what students have learned after instruction has been completed.
