Depending on the subject or the activity, you can assess your students differently. Structured quizzes or exam-style assessments work well for informational content. They are an effective way to measure whether the students understood and memorized the content. Open-ended questions or assignments help assess critical thinking skills and how well learners have understood the subject. Self-assessment works better in coaching or non-structured learning, where the students set the goals themselves. Evaluation forms can also work as a kind of self-assessment or reflection for students.
