    KINESCOPE A device which produces a filmed record of a television broadcast which can be shown subsequently by means of a conventional film projector. LANGUAGE LABORATORY See Chapter 9. LINEAR PROGRAMME A form of programmed instruction in which each unit (or frame) of the programme is small and so simply presented that wrong answers are rare, and in which the student progresses successively from one frame to the next (see para. 354). MICROPROJECTOR An instrument which projects highly-magnified pictures of microscopic objects on to a screen. MICROWAVE LINK A precisely-directed radio link between transmitter and receiver in closed- circuit television, using frequencies of about 10,000 megacycles per second. OPEN-CIRCUIT TELEVISION (octv) The broadcast transmission of television signals to an unrestricted audience (para. 264). OVERHEAD PROJECTOR An instrument which projects pictures on to a screen from large transpar- encies placed horizontally. RADIO FREQUENCY When television picture signals are to be transmitted a distance of more than 1,000 ft., video-frequency signals are not satisfactory. The pictures are accordingly carried on a much higher radio or carrier frequency which may vary in practice from tens to thousands of megacycles per second. REMEDIAL LOOP A term used in programmed instruction to indicate a series of supplementary or corrective frames in a branching programme to which a student may be directed when his response to a previous frame shows that he needs additional information or guidance. SCRAMBLED TEXT-BOOK A form of programmed learning presentation particularly associated with ‘multiple-choice’ programmes in which the instructional sequences each occupy a page, but successive sequences do not appear on consecutive pages. SINGLE-CONCEPT FILM Generally an 8 mm film of short duration (up to 44 minutes), in the form of a continuous loop in a cassette, which deals with a single educational concept and is normally silent, the teacher giving his own commentary (see cassette-loaded projector).
