Assessment of Learning, which is summative, is what we do in tests and exams. I would say that this is important to prepare the students for the national exams.

Assessment as learning is more challenging - demanding a certain level of maturity and high level of self-directedness. I remembered giving this assignment in which students go through a decision making quiz (or game as it was called on the site) and questioning their own thinking which they posted on padlet.
