This article describes a visual language comprised of abstract shapes that has been shown to be effective in communicating prior knowledge between and within members of a small team or group. The visual language includes a set of geometric shapes and rules that guide the construction of the abstract diagrams that are the external representation of…

Geometry is required for many secondary school students, and is often learned, taught, and assessed more in a heuristic image-based manner, than as a formal axiomatic deductive system. Students are required to prove general theorems, but diagrams are usually used. It follows that understanding how students engage in perceiving and reasoning about…

The current experiment compared the development of encoding preferences in learning disabled children and non-disabled children. Both learning disabled (LD) and non-learning disabled (non-LD) boys from grades 2 and 6 were given a false recognition task. To measure the relative dominance of attributes encoded by the two groups at the two ages,…

A study tested the theory that an item that stands out from its background is better remembered than one that is similar to the background (the isolation effect). Specifically, the study examined whether the isolation effect would be greater when there was a larger and more confusing mass of background items, whether position of the isolated item…

One theoretical model for understanding the visual event suggests that a visual event has both a surface (descriptive) and a deeper (experience) level of understanding. Both levels are needed to comprehend and appreciate images, with each level affecting the other. A person's perspective is an important part of the visual event, which depends upon…

Event-related Potentials (ERPs) were recorded to both auditory and visual stimuli from the scalps of nine autistic males and nine normal controls (all Ss between 12 and 22 years of age) to examine the differences in information processing strategies. Ss were tested on three different tasks: an auditory missing stimulus paradigm, a visual color…

The purpose of the eight studies reported in this paper was two-fold: to identify some of the relationships that exist between the unique properties of diagrams and various aspects of cognitive processes and learning, and, subsequently, to derive principles from these relationships that would direct the design and use of diagrams in the classroom.…

Gestalt theory deals with the act of thinking and the construction of concepts in a situated manner, and, therefore, could be used to study how meaning is extracted from a visual display. Using the Gestalt framework of form cues and their usage patterns in the perception of, and learning from, visual media, researchers could study frame, line…

Noting that students fail to fully realize the advantages of notetaking as a process to develop a personalized learning system, this paper proposes the use of visual constructions to help students re-establish for themselves the unity of knowledge and to create personalized meanings to this knowledge. The paper summarizes the benefits of…

This report uses mental model theory to create a taxonomy of picture functions in order to relate these functions to learning theories. A rough outline of picture functions is presented, consisting of a retrieval function, a focus function, a construction function, and a supplantation function. It is suggested that this taxonomy could be helpful…

This paper proposes that three properties of graphic materials can be manipulated by instructional designers to model cognitive processes and thus help students learn. These properties are: the distance of elements in the graphic display from each other, the orientation of the elements to each other, and the sequence in which the elements are…

A research study was designed to test the relationship between the number of eye fixations and amount of learning as determined by a criterion referenced posttest. The study sought to answer the following questions: (1) Are differences in eye movement indices related to the posttest score? (2) Do differences in eye movement indices of subjects…

It is necessary to provide a comprehensive program of visual literacy skill development to provide a firm foundation for reading comprehension. A taxonomy of visual literacy can suggest an outline for such a program. Once the student has been made aware of the desired thought processes in familiar contexts, it is then appropriate to guide the…

An experiment was conducted in which the relationships of basic television and film codes to particular literacy mental skills were examined. Different versions of the same film, each focusing on a different code, were produced and shown to fifth graders. It was found that children with initially better mastery of the relevant skills extract more…

This paper describes a theoretical framework for the investigation of some specific types of visual learning difficulties commonly experienced by biology undergraduates. The framework was developed based on the findings of three simple qualitative pilot studies. A variety of neurological, cognitive and cultural mechanisms can influence what humans…
