This may be more about building self-discipline with respect to technology versus finding schools that ban it entirely. If you don’t learn to find this balance in college, it will be hard to do so in the job market, where technology is ubiquitous, unless you are doing away with working in the service industry all together. But hopefully you already know this.
Anyway, at Reed my professors barely if ever project things on the board. A lot of them simply write on the board and look at the texts (for humanities courses). Some of them outright ban technology in class. Class resources are on the internet for some profs. But yeah, it will be hard not to use technology because in college you need to find information quickly and the internet is very good for it (going through titles of chapters in books, for instance), and you will definitely get distracted because sometimes this goes for hours on end. Ever since personal computers became a thing, colleges have demanded a lot more writing from students, which is fair given how easy technology has made it.
If the profs are older, or teach humanities, they will stick to the written word and stay away from the projector, but say, in the social sciences, my professors have done things like skyping with well-known researchers, and demonstrating tools like STATA and R to do research and things like that. In math, most professors simply use textbooks and the chalkboard. In science, there is a lot of use of technology. So yeah, endpoint is it depends on your discipline, but limiting yourself to a technology-free environment may be nearly impossible, and it definitely restricts your options a lot.
I’m with you on one point, though; I absolutely HATE powerpoint presentations, especially when people just put troves of information on them. But I also use technology nearly all the time, because I have to be on it with emails and working with campus resources and communications that are nearly all online.
