Abstract
The purpose of the study was to develop and evaluate courseware for computer- based interactive videodisc (CBIV) instruction for teaching essential skills in the visual diagnosis of selected problems in beginning trombone performance. The following questions were addressed: (1) what problems in trombone performance are amenable to visual diagnosis using CBIV instruction; (2) which of the problems can be described in terms of observable behavior to provide a basis for the statement of a behavioral objective; (3) what experiences are pertinent to the attainment of each behavioral objective; (4) what hardware and software capabilities are required to provide an appropriate setting for these experiences; (5) what courseware content is appropriate for providing for these experiences; and (6) what will be the results of using these materials and hardware to develop visual diagnostic skills? A review of the literature revealed psychomotor problems in four performance areas which are amenable to visual diagnosis: posture; hand grips; embouchure; and slide technique. A panel of experts comprised of artist-teachers of trombone and music education faculty teaching instrumental methods assisted with the selection of problems for the study. Characteristic behaviors of acceptable and unacceptable performance were defined and stated as behavioral objectives. Selection of experiences and decisions about hardware and software capabilities required to provide for these experiences preceded the development of the courseware content.
Courseware development included videotaping and pilot testing examples of correct and incorrect performance, post-production editing, videodisc mastering, and programming the courseware. A three-quarter inch premastered tape containing examples performed by an adult model and three junior high school trombonists was prepared for mastering the videodisc.
Data were collected from three sources: a pre-treatment questionnaire, a database program which stored information on each subject's interactions with computer and post-treatment interviews with six of the twelve subjects. Analysis of the data revealed that subjects found the use of full-color motion sequences and the feedback provided by superimposing computer generated text graphics on the videodisc images beneficial for teaching skills in visual diagnosis. Results of the study also support using Level III CBIV instruction to supplement classroom instruction in instrumental methods and techniques.
