I agree with math, science, and politics not getting any more complicated than they were in the 1940s and 1950s. But it does depend on the science and math though. Most math is done using computers today and there are still a large percentage of people who don't really know how to use the programs associated with the math and science programs not to mention the computer itself. The different kinds of science like computer science and even advanced stats classes can use PowerPoint which can actually help the teacher more so than the student. For a matter of fact all of my stats classes in college used PowerPoint exclusively. In business classes PowerPoint is a must. There is so many things you have to go over in business classes PowerPoint doesn't even help lower the amount of reading you need to do in the classes. It does help in making the classes more efficient and I'm willing to bet political classes that use PowerPoint are more efficient in how they are ran. When I was in college I only had about 6 classes where PowerPoint wasn't used at all. My 4 literature classes and my 2 classes in Spanish. The two history classes I took even had PowerPoint presentations. PowerPoint does help the student a lot but the benefit is more so in the teachers favor. The PowerPoint slides that I used and received from my teachers I used as big note cards since it was nearly impossible for me take all the notes I needed to study. I would say the majority of the people in my business classes used them in the same way.
