Correct Response: A. Direct observation of a student's use of a new motor skill in an authentic setting would provide the most accurate assessment of degree of mastery of the physical skill. Interviewing the student or using a writing task for assessment would be more effective for testing conceptual knowledge, such as understanding of rules for games, strategies, and skills important to an activity (B, D). Recognizing the learning stage involved in the student's execution of the skill can help the teacher evaluate the ways in which the student is thinking about performing the physical movements (C).
