I appreciate having examples to show teachers of other teachers engaging students in the engineering design process. I find that many teachers have a hard time letting go of explaining the "how and why" prior to engaging students in activities. It makes me cringe when I hear teachers tell students what they are going to do and what the result will be prior to having them engaged in the activity- to me, it takes all the wonder out of the learning experience. Thank you for providing these examples that show teachers how to develop and inspire that sense of wonder and creativity in students!
