I started out as a Vocational Home Economics teacher, in a K-12 school, so I worked with a nine-week "wheel" of seventh graders, and with vocationally tracked junior and senior students for Food Prep and Fashion Design. I had two huge classrooms; one was for academics and the other was a food prep lab with professional equipment, such as slicers, microwaves, convection ovens, mixers, etc.
Then I got my Master's degree in English education and worked in a classroom overlooking a cow pasture. I had a real chalkboard--and not much else. We used the old movie projector reels to show films, and overhead projectors, and Dukanes (film strips and cassette tapes) for anything else. Actually, there was one year the administration pushed System 80's to teach vocabulary. They were record players with punch cards.
Students had to go to the office to use the stationary black phone, with the dial, to make their phone calls. I used a ditto machine for my handouts--copiers were strictly monitored, and they always broke down anyway.
