re: Tablets Rock On: Education Tech Through The Ages
Your review of educational/instructional technology is narrow and restricted. Technologies, as you demonstrate by the inclusion of printing and correspondence classes, are broad and varied in how they interface with humans and with the content being presented. You left out an enormous field of technology in the history of education, that of the use of moving images, particularly film and video. From WWII to the beginning decade of the 20th Century, film and video use in the classroom was extensive and pervasive.School districts and regions maintained huge film libraries with elaborate distribution systems.Whole state instructional television networks broadcast hundreds of curricular series into daytime classes, used by teachers who had by prepped with training and provided teacher's guides for each series. The Agency for Instructional Technology, for which I worked, pioneered off-air recording rights so teachers could record instructional video and use programs at their pleasure. Just remember that computers are not the totality of technology.
