Which method is least effective for assessing student knowledge?

Class attendance is the least effective method for assessing student knowledge because it does not provide any direct information about what the students have learned or understood. Simply being present in the classroom does not indicate whether a student has grasped the material being taught or can apply that knowledge effectively. Attendance can be influenced by various external factors and does not reflect engagement or comprehension.

In contrast, practical demonstrations offer students the opportunity to apply what they have learned in a hands-on scenario, providing a clear indication of their ability to translate theory into practice. Quizzes are designed to test knowledge directly, allowing instructors to assess understanding and retention of material efficiently. Feedback during discussions encourages active participation and can reveal students' thought processes and comprehension levels, making it a valuable assessment tool. Thus, while attendance is important for participation, it does not serve as a reliable measure of student knowledge or skill proficiency.
