An experiment to determine the effectiveness of slides and audio-tapes for presenting manipulative demonstrations in graphic arts

Abstract

The purpose of the study w as to compare a slide-tape method of presenting demonstrations with teacher-presented demonstrations in junior high school graphic arts. The experiment was designed to examine initial learning of (1) terminology and procedural detail, (2) operational procedure, and (3) ability to perform the operation. The rationale for such an examination was to identify ways of reducing teaching time by using an automated device for certain structured activities like demonstrations. The experiment was conducted in four junior high schools in Columbus, Ohio, during the 1966-67 school year. Each school had two classes of graphic arts taught by the same teacher. A total of 134 eighth grade students participated in the experiment. The classes were 12 weeks in length and provided the students with their first exposure to graphic arts activities. Equivalent facilities were available in each of the four laboratories. The two classes in each school were randomly assigned to be either the teacher-demonstration group (control) or the slide-tape group (experimental). ...
