Your classmate Aiden and you have assembled a mechanical toy that is supposed to move across the floor, but it does not work on your first attempt. Your teacher says this is ok because you have failed forward. What do they mean?
Every idea or prototype will work as intended; you should stop working on the toy.
By learning what does not work with your design, you have learned how to improve on your next attempt.
You have failed this assignment by not getting it correct on the first attempt and should give up.
By learning what does not work, you realize that you cannot do this and should drop the class.
