Hello Tingyan,
The image about Experiential Learning Cycle you inserted in your post is very informative, helpful, and useful for us to have a better understanding of this learning approach. I really liked that you use this cycle to analyze how to use it to the blueprint and final project. It is very clear and easy to understand. As you described in your post, the purpose of experiential learning is to help learners to learn the knowledge through practice and experience and learn from mistakes, consequences, and achievements. In my opinion, it is important in learning because it can not only help learners to develop their critical thinking skill, but also can have more cognitive ability.
