Final answer:
The most appropriate method for determining if students have mastered course content through testing is by using summative assessments.
Step-by-step explanation:
If you wanted to determine if students had mastered the course content through testing, you would rely most upon Summative assessments. Summative assessments are typically given at the end of a course or unit and are designed to evaluate a student's overall understanding and mastery of the content. Examples of summative assessments include final exams, standardized tests, and end-of-unit projects.
In contrast, formative assessments are used throughout the learning process to provide feedback and guide instruction. Performance assessments assess a student's ability to apply their knowledge and skills in real-world contexts. Self-assessments involve students reflecting on their own learning and progress.
