4 Excellent resource for STEM and engineering
I have been using this podcast for years in my design process and STEM workshops for teachers! It expertly and clearly goes through the engineering design process, explaining each step. I use this as an introduction and have even copied their use of symbols for each step to create handouts to students as they go through the steps (see my collections). If I could have put 4.5 stars I would have. My only hesitation in giving it a 5/5 is that the sound is muffled and the video quality is medium resolution - making it a bit tough to use in a group setting. All in all, a fantastic resource that I have come to rely on heavily in my pd workshops.
