Hello, I was curious, is there anyone out there doing research on how to effectively teach engineering? I have noticed that my engineering textbooks are very old, new editions come irregularly, which I can understand because the number of students buying the books is appreciably less than say a calculus book. However, the textbooks that come out are very dry with no pictures! Or the pictures are very crude diagrams. I think the diagrams with color that you see in modern physics and math textbooks enhances and gives visuals that aid in student learning. It seems also that the problems in an engineering textbook are far too few. A chapter might have 20 problems, and maybe only 5-6 of them are of any real quality, the rest is junk. A math textbook like Larson or Stewart will have 100 problems per section of a chapter, but maybe 40-50 of them are good problems. Even a physics textbook like Halliday will have 20-25 decent problems per chapter to work on. It seems like the engineering textbook authors are far behind the curve and using unsound pedagogical techniques. I think it's time to rewrite these books to have more visuals and follow the path that has already been set by physics and math textbook authors. These engineering books look like a math textbook from the 1950s. I know you shouldn't judge a book by its cover, but I mean the covers are just black with the textbook name and author on the front, not even a cool image there! You can say ''well then write your own'' and my answer is if I ever got a PhD in my engineering discipline, that would be something I would definitely do!!
