I think that the bottom line is that it is fine using aids to calculation but you need to be able to tell if the result is wrong for what ever reason, be it malfunction or user error.And it doesn't matter if that aid is log tables, slide rule or electronic calculator.
Should electric engineers use matlab instead of doing fourier transform by hand?
liudr: In a classic picture of education, teachers create content to teach to students. It's hard work to create new content especially when someone has been on the job for a number of years. If Arduino as a platform (or something else) can help shift content creation partially to students (they have a lot of untapped brain cells), then this may change how teachers teach. One time I assigned an extra credit problem to my college students: to simulate cycloid motion, one of them created an android app. It was cool and correct. I have it on my phone. So every time I go over the same content, I show the app to my students as a demonstration. That student was not even a programmer. He got interested in app programming and my assignment gave him a goal and he achieved it. This is a lot better and easier on me than me trying to create one myself smileyBelieve or not, ed colleges like the one in my university, stress a lot more over pedagogy than content. Our ed grads fail content exam to a point that their parents are complaining to the ed professors that their kids aren't getting jobs. I get the same complaints from ed students I interacted with. Trust me, these science ed majors don't know enough science to teach science. That could be a reason teachers hang on to old content even wrong ones. My state is considered as top 4-5 in US science engineering preparedness for college but I simply don't see it. Graduation requirement for high school is still geared towards finding a job as HS grad, not towards entering college. 1 year of physics or chemistry WILL be required in 2015 grads. Before then, it's OK to keep taking biology! I had 5 years of each, all required! That's from 3rd world country.By the time these engineer-wannabes enter college without physics, it's too late. They could have done it in high school for free.
