Developing Instructional VideotapesThis article describes several sessions conducted aimed at developing instructional videotapes that feature the first 18 months of an infant's life. Ten different videotaping sessions were conducted, beginning when the infant was 18 days old and ending when he was 16.5 months old. After the ten videotaping sessions were completed, the first author developed scripts to be used to guide the production of classroom videotapes. A professional narrator, working with a sound technician, then recorded the narration for each scene on audiocassettes. Finally, classroom videotapes were assembled, scene by scene, copying from the original session videotapes to master tapes and then adding narration to the masters. The results are five videotapes of from 15 to 20 minutes duration. Each tape pertains to only one aspect of development. The title of the series is Observations During Infancy. Individual videotapes are; Sensorimotor Thinking, Gross Motor Development, Fine Motor Development, Social Development and Early Language. Trnavsky, P. and Willey, D. L. (1984).
