In the past, opaque projectors (58 per cent), silent filmstrip projectors (46 per cent),…

Technical features of Penn State's Instructional Media Center are described. Unlike many other instructional units, special attention has been paid to the physiological requirements for learning in its design and construction, i.e., acoustics, lighting, visibility, and air conditioning. The building contains many unique features which may be…

Presented is the final report on development of an aural study system which involved approximately 1000 visually handicapped elementary, secondary, and college students. Given is background information such as the relative effectiveness of reading and listening during study, and factors that affect listening comprehension such as learner…

Focusing on the current status of the language laboratory in instructional use, this report stresses the need to employ a systems approach in the selection and operation of laboratory equipment. The author points out the interrelatedness of the key factors in any system, including: (1) people, (2) method, (3) instructional materials, (4)…

The authors define environmental simulation as the selection, manipulation and/or modification of any number and combination of the five senses to create an experience which simulates a real or imaginary environment.
