There are various other terms which are alternatives, most obviously 'instructional technologist'. There have been various names for institutions specialising in the activity. The description used originally at the UK Open University was 'Applied Educational Sciences', changed later to 'Institute of Educational Technology'. To produce the landmark program "Sesame Street", the Childrens' Television Workshop employed applied psychologists to pre-test all programs. This was a typical activity for educational technologists even if they were not called by that name.
