A teacher in 1975 would have used what technology to create handouts for his or her students?
A) Ditto duplicator.
B) Laser printer.
C) Copy machine.
D) Scan converter.
I want to say C but would like a second opinion.
We didn't have copy machines yet! It's D.
Although schools may have had copy machines in 1975, if I remember correctly, we were still producing multiple copies on the ditto duplicator machine. Copy machines and ink were much too expensive then to use for student handouts.
You old timers -- do you remember the smell of a freshly run ditto with purple ink? <g>
Oh, you bet! And I also remember mimeograph machines whose masters were absolutely unforgiving!
Our school didn't have any copy machines until about 1980 or so ... and then ONE machine for about 70 teachers and all the others on the staff!
To determine the most likely technology a teacher in 1975 would have used to create handouts for students, it is helpful to consider the available options at that time.
Option A) Ditto duplicator: The Ditto duplicator, also known as a spirit duplicator or mimeograph, was a common printing technology used in schools before the 1970s. It involved creating a stencil and using a hand-cranked machine to reproduce multiple copies. However, by 1975, the popularity of ditto duplicators had started to decline as photocopiers became more accessible.
Option B) Laser printer: Laser printers were not commonly available until the 1980s. Therefore, it is unlikely that a teacher in 1975 would have used this technology to create handouts.
Option C) Copy machine: Copy machines, also known as photocopiers, were emerging as a practical alternative to ditto duplicators in the mid-1970s. They offered faster and higher-quality copies, making them more suitable for creating handouts. Considering this, option C is a reasonable choice.
Option D) Scan converter: Scan converters, which are devices that convert one video signal format into another, were not typically used for creating handouts in educational settings. They were primarily designed for video production and broadcast purposes, so it would be less likely for a teacher in 1975 to utilize such technology for handout creation.
Based on the available options and the technological landscape of 1975, option C) Copy machine seems to be the most reasonable choice for the technology a teacher would have used to create handouts for students.
