Card Sorting provides learners with interactive experiences that challenge their critical thinking, decision-making, and problem-solving skills.
What exactly is Card Sorting? It is a dynamic learning activity that involves organizing concepts, ideas, or information into meaningful categories or sequences. By presenting learners with a set of cards, each containing a piece of content, Card Sorting enables them to sort and group those cards into categories. This interactive exercise encourages learners to actively participate in the learning process, enhancing their comprehension and retention of the subject matter.
