Dimensional preference tasks in both visual and haptic modalities with three dimensional stimuli varying in form, size, color, or texture were presented to 64 children. There were 16 subjects at each of four grade levels: preschool, kindergarten, grade 1, and grade 3. On each trial, the subject was presented three stimuli and asked to tell the…

The effects of interspersed trials on prompted (P) and confirmation (C) paired associate learning were studied in 64 institutionalized educable mental retardates. Subjects were instructed to learn eight pairs of pictures which were presented by a slide projector. There were four groups in both the P and C condition. The treatment for these groups…

Two ways of teaching a course in adolescent development and learning were compared. Sections of normal size were taught as usual, while large sections had instruction augmented with televised illustrations. With the exception of these illustrations, resources were the same for both classes and included a programed text. Results on two types of…

In an attempt to study the role of pictures in connection with the perception of information via television, the pictorial accompaniment to some news items in a simulated television news program was systematically varied. The retention of the verbal message and the perception of the news items were measured for the different illustrations. It was…

The history of some computer-assisted instruction (CAI) strategies is traced. A number of components of computerized instruction systems are described and explanations provided on the influence these components have in the development and production of a CAI system. A description of the interaction between a student and a CAI system is presented…

A study was designed to determine if multiple-image (four frames at a time) presentations of stimulus material would provide a superior learning mode for students when compared to the usual single image linear presentation of the material. Students who were learning to use audiovisual equipment in an automated laboratory situation were subjects:…

Three visual media--sequential still photographs, slides, and motion pictures--were investigated to discover how effectively each of the three help to convey concepts involving time, space, and motion. A total of 594 subjects were selected from an introductory independent-study course in botany and randomly assigned to one of the three…

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…

This study examined the effectiveness of a simple browse search strategy and a more complex analytical strategy with 25 high school students, using an electronic full-text encyclopedia. Captured keystrokes and student essays were analyzed for retrieval performance and information application. No significant differences between types of search…

Fourteen groups of college students were shown a 30-minute film, introducing an assembly kit, in one of seven versions of visual-narrative overlap. For best associative recall of object names, results indicated visuals should be presented before or simultaneously with text in dual-media presentations. (Author/BS)

A study of variations in pupils' prior knowledge for their influence on the sequencing mode of text presentation found prior knowledge reduced the effect of size of sequencing procedures. A second experiment comparing performance of pupils with low prior knowledge level using websequence and linear sequence found webteaching was superior.…

Two experiments investigated effects of pictures on kindergarten children learning to read nouns. Results indicate instructions to associate word and picture and viewing of the word prior to presentation of the picture failed to improve performance. Children who learned words in absence of pictures recognized more words on post-learning trials.…

An experiment testing for the learning differences between students who received BBC radio broadcasts as part of instruction and those whose instruction was based on conventional teacher notes. (HB)

Based on a thesis submitted to the Graduate School of Purdue University by the first author. (Author)

Differential effects of university supervisors and cooperating teachers as observers on the verbal behavior of student teachers were studied. The tape-recorded data showed remarkable stability over the three observer conditions--no live observer present in the classroom or either the university supervisor or the cooperating teacher present.…
