Abstract
Do you remember those balmy days in the ‘60s when British media ruled the airwaves, when the Beatles’ records sold in millions … and when the Centre for Educational Television Overseas kits with pre-edited 16 mm film sequences, caption cards and scripts (even camera cards) to grateful producers from Ghana to lran. Do you remember the subjective and sentimental prose which used to creep into the research–and–evaluation literature. Here's a sample passage, about the Niger tv experiment: ‘… the pupils receiving the television instruction have much happier faces, are more spontaneous, and seem far more interested in attending school. In the classroom they are free and joyous, and sometimes seem to be absolutely enchanted.’
