Children are involved in self-assessment when they look at their own work in a reflective way, identify aspects of it that are good and that could be improved, and then set personal learning targets for themselves.
Self-assessment involves metacognition
the process of being aware of and reflecting on one’s own learning.
Self-assessment skills include effective questioning, reflection, problem-solving, comparative analysis, and the ability to share thoughts in a variety of ways.
