This lesson took two days for us to complete. We finished it up today.
I did a lesson similar to this with one of my other classes where students have to research come up with a product to solve a problem in school, research what is out there, design a product, create an advertisement and then design it for the 3d printers.
The issue that I ran into here is that students jumped into research looking for something to create rather than looking at what is out there (I hope that makes sense). One student was looking at 3D printers rather than the manufacturing as a whole. He was really struggling in his research because he wasn't sure what to research exactly.
On day 2, I started off emphasizing the idea that they are looking for innovations. We ran through the worksheet as a class looking at wearable devices, and specifically smart watches. The students were to write down anything and everything new that they were finding. There was also the issue that students didn't really see smart watches as innovative because they have been out for 2 or 3 years. There was almost this idea that step counting, reading text messages on your watch, and touch screens were old news. I had to point out that these were new technologies and worth acknowledging on their paper.
Overall, I think the lesson was good. I really like the video from code.org, and my students also loved it.
