Kepu Li Posted over 1 year ago One relatively simple and cheap change can be made to schooling to reduce opt out and drop out rates. This is a amazing idea, in this way, students will have more passion in seeking knowledge and "climb to the final stage." I mean it can be a huge motive for me! But just for noticing, there are few problems that can be happen through this grading system. Because each student has a different path of learning, it's hard for teachers to schedule classes; students might have a huge gap of stages in learning. Also, when some students finish the course earlier, it can also deal pressure on other students to doubt themselves which might cause other mental problem than only a feeling for failure. Plus, Because each student has a individualized learning path, there will be much more effort paid, in another word, this idea might met challenges while normalizing.
