Three sets of audiovisual lessons were presented on either a prototype videodisc player or with film/audiocassette. Both groups of trained soldiers performed significantly better than a control group. On two of the lessons, no difference was found between presentation modes--the third favored film/audiocassette.

Three types of stimulus materials (text, film, and live demonstration) were used to teach graduate students cardiopulmonary resuscitation; and verbal learning and a motor skill task were measured to determine the effectiveness of the different media. No significant differences were found among the three modes of instruction. (Author/JEG)

The purpose of this study was to measure and analyze viewers' electroencephalographic reactions to motion and still pictures, and to increase knowledge on the differential impact of the two modes on brain wave production. Since beta brain wave indicates focused attention, an additional purpose was to determine whether the two media differed…

The purpose of this study was to compute and analyze descriptive indices of efficiency assessing the relative effectiveness of a verbal and visual color code applied to self-paced learning and testing materials. The sample consisted of 176 college subjects randomly assigned to one of four treatment conditions receiving black/white (B) or color…

A controlled experiment studying effects of adding voice-over sound to a silent electronic text service tested program acceptability and memory retention. Results indicate no significant differences in ratings for acceptability although the test for memory retention resulted in significantly higher scores for the sound group on recall and…

Discusses research on the effectiveness of computer-based instruction (CBI) and proposes computer modeling as a tool to redirect CBI research toward more theoretically relevant and prescriptive research. Limitations of media comparison studies and media replication studies are described, and computer modeling in CBI research is reviewed. (48…

This study examines the effect of an entering behavior, i.e., the level of general knowledge of the subject matter, on the instructional effectiveness of illustrations which integrate abstract and realistic visualization. Subjects were 414 public school students who were divided into three groups according to their general level of knowledge of…

The relationship between patterns of learning ability and the amount learned under different instructional conditions was studied. Scores for each of 44 Air Force trainees were obtained on several standardized tests of achievement and ability. Each subject then participated and was tested in five learning situations: (1) listening to taped…

Two variables that designers should consider when developing computer-based instruction (CBI) text screens are text density, which manipulates the context of the information presented, and screen density, which is a measurement of the amount of information presented at one time on the screen. A study on text density was designed to identify…

In order to compare the instructional effectiveness of realistic and non-realistic color cueing on visualized instruction, an instructional unit on the human heart, using slides and an audiotape, was presented to 244 college students. Four treatment groups received the same oral presentation, with the addition of different types of visual…

An experiment was conducted to examine the effects of presentation mode, picture content, and serial position upon the recall of brief television news items. Fifteen items were presented in either video- or audio-only mode to 40 subjects. The results are discussed in terms of various imagery hypotheses. (Author)

The computer assisted instruction (CAI) program "CAI Webdi," an instructional package for deaf education which utilizes CAI with audiovisual aids, was used in a comparative study of computer assisted and videotaped instruction. Based upon a formative evaluation of CAI Webdi with post secondary deaf students, an instructional television…

Studies whether presentations by an iconic system (pictures) or a linguistic system (print or audio) aid learning. Tests given fourth-to-sixth graders showed alternation between systems, using each to assimilate information. Learning was not as effective when content differed between the systems and this information was presented simultaneously…

This study examined whether the sources of information children use to substantiate story-based inferences are influenced by the medium of delivery. The 48 third grade students who acted as subjects were stratified by sex and randomly assigned to one of two media conditions; i.e., each child was presented an African folktale either (1) as a…

The relative effectiveness of teaching methods using programmed instructional materials to teach musical percepts--phrase, theme, introduction, interlude, coda, binary form, ternary form, and rondo form--was studied. The 124 undergraduate elementary education majors used as subjects were found to be similar in aural perception, length of musical…
