Educational technology 30 years on: why hasn’t education changed much?
Tony Bates nimmt uns mit auf eine kleine Zeitreise, weil ein Buch aus dem Jahr 1984 (!) mit dem Titel “The Role of Technology in Distance Education” neu aufgelegt werden soll (!?). Es ist erstaunlich zu lesen, was es vor 30 Jahren bereits alles gab. Natürlich Fernsehen und Radio, via Kabel und Satellit, Computer assisted learning (CAL, im Experimentierstadium), Teaching by telephone, Teletext, usw. Und natürlich hat das Internet viele dieser Dienste zusammengeführt, vieles ist einfacher, kostengünstiger, ohne dass die Kosten für Bildung bzw. Hochschulbildung insgesamt gefallen wären. Tony Bates wundert das nicht:
“What’s keeping up the cost is the need for learner support – facilitating learning through discourse and dialogue. Technology in fact is still a relatively small cost within the overall cost of teaching. Faculty salaries constitute at least two thirds of all costs and while we still require an instructor:student ratio of roughly 1:25 in higher education, costs will not come down significantly. However, I am not convinced that we can effectively substitute that instructor:learner interaction by technology alone without losing quality.
But we could still be doing more to reduce costs, and/or improve quality, as follows: … open textbooks … greater use of open educational resources and sharing content … get faculty to teach more … re-organise the teaching of large classes … major re-design of teaching … build new institutions.”
