Spatial and Visual Representations, Abilities, & Literacy

Overview

Overview

Spatial thinking and representation is possible without visual representations. Non sighted people are capable of spatially representing objects and events, which sighted people probably do also, but because we are sighted, we often automatically connect spatial thinking to visual representations.

The quality of a representation depends on the time a person takes to construct it. The construction which, can be internal (mental) or external (physically in the environment) for both spatial and visual representations. As we draw a picture and take time to add detail to an external representation, so too are our internal constructions improved with time.

Historically internal and external representations have been described in three general categories 1. concrete, 2. semi-concrete or iconic or pictorial, and 3. abstract or symbolic. However, as represented below, there can be a continuum between these categories for most representations.

For example: a bowl can be spatially represented as half of a curved sphere with an opening into the curve. Spatially it can be rotated so the opening is on the top to hold something or on the bottom to dump out its contents. This is possibly represented internally simply as opening on top, curve on bottom; or when inverted opening on bottom, curve on top. To represent it visually one could internally construct a mental picture of a bowl positioned as bowls are normally or inverted. The visual representation may have details with properties such as color of the bowl and markings or represented by a simple u shaped curve. Depending on the time we take to construct the representation and the complexity of what is being represented.

For example, a face is most likely more complex than a bowl and can be represented with a greater range details. The following figure shows this and also how Bruner categorized this continuum in three categories.

In mathematics, concrete representations are shown with objects (counters, cubes, shapes, rods) and actions on those object to represent mathematical information; semi-concrete or iconic representation are shown with drawings or pictures of those concrete objects; and the abstract representation replaces the concrete objects and semi-concrete representations with mathematical symbols and numbers.

Spatial thinking and representation begins early with infants well before any verbal communication and is the basis for:

Spatial visual thinking and related descriptions

• Geometry is the study of spatial objects, relationships, and transformations that have been formalized and the axiomatic mathematical systems that have been constructed to represent them.
• Gestures are external representations to help in communication.
• Instructional Activities to Develop Visual Spatial Abilities
• Spatial reasoning is the set of cognitive processes by which mental representations for spatial objects, relationships, and transformations are constructed and manipulated.
• Visualization includes written text, images, symbols, scale diagrams, cutaway diagrams, cross-sections, flow charts, organizational charts, cycle charts, webs, hierarchical diagrams, dichotomous charts, network charts, bar graphs, circle graphs, line graphs, three-dimensional graphs, time lines, bird’s eye view maps, context maps, altitude maps, tables, graphic designs.
• Six Modes of Visual Learning
• Spatial / visual representation is not created as if the mind is a video recorder storing images for future reference where perceptual snapshots can be referenced mentally in the manner as one looks at old pictures in a picture album or video on a monitor. It is the building of mental representations from active manipulation of the environment in relationship to a current best fit mental representations.
• Visual and spatial thinking pervades all human everyday tasks, like finding ones way through a shopping mall and back to your parked car, arranging items in drawers or on shelves, rearranging furniture, mental maps, reading comprehension, all construction activities, and for making and interpreting gesture. Visual and spatial relationships include two and three-dimensional drawings and models representing objects, events, and ideas. Objects and ideas such as molecular structures, DNA, cells, magnetic fields, circulation of blood, operation of body systems, solar systems, galaxies, interactions, maps, circuits, and virtually any system and how its subsystems interact, geometry, mathematical properties of number, number patterns, mathematical operations, functions, graphing, representations of any mathematical idea, and as a tool for problem solving.
• Visual learning is the process used to become visually literate.
• Visual literacy is the ability to decode visual actions, objects, symbols, and other images and gain meaning from them and to encode thoughts and ideas and express them with visual representations.
• Visual spatial skills

Visual Spatial Research

• Gestures which are made simultaneous and spontaneous do not slow down a personâ€™s thinking or hinder it.
• When people who were taught something, while sitting on their hands, compared to a group taught the same thing while not sitting on their hands, performed better.
• Peggy Blackwell summarizes gender differences as follows: Women, as a consequence of socialization or genetics or both, have difficulty perceiving relationships in and among three-dimensional objects. For example, some women find it difficult to drive a car in reverse, or to determine how a mechanical object works simply by looking at it. Many women do not automatically learn, at home or at school, the total concept of space, which includes direction, distance, perspective, movement, and relationships of objects to each other in space. Women have consistently shown a sex differentiated lack of what is called spatial visualization and spatial orientation.
• Barbara Moses found that the ability to think visually is not innate and can be improved. She found a strong positive relationship between problem-solving and visual/spatial thinking skills. She also found the greatest improvement among female students who had few previous direct experiences with visual thinking.
• Smith and Schroeder found that fourth graders who received training in visual thinking outperformed those who did not and there was no difference between the sexes in how training affected their abilities to perform visual/spatial tasks.
• Herbert Cohen used SCIIS materials with fifth grade students and found both males and females significantly improved in logical and visual thinking abilities.
• Smith and Litman compared training of fourth graders with training of adolescents and concluded that both can benefit from instruction at the fourth grade level; but if instruction is postponed to early adolescence, only boys benefit.
• Pallarand and Seeber found that community college students significantly increased their visual thinking abilities after instruction that was based in large part on the SCIS fourth grade unit "Relative Position and Motion".
• Lord found that regular experiences with spatial tasks significantly improved visual and spatial thinking of college biology students.
• Siegel and Schadler, found that that boys were more accurate in constructing scale models of their classroom than girls. Herman and Siegel found that boys outperformed girls in a task of reconstructing a model of a large scale model town that they had explored.

Summary

These differences might be explained by the differences in toys that boys and girls play with, differences in parental responses to girls and boys manipulation of toys, differences in amount of space boys and girls are allowed to explore and play, amount of time spent outdoors, and distances allowed to roam from home.

Research supports three ideas:

1. Boys tend to outperform girls on visual/spatial tasks;
2. Visual/spatial abilities can be improved through instruction; and
3. Both sexes benefit from planned visual and spatial experiences, but girls benefit most if a narrowing of a gender gap in visual/spatial thinking is achieved.

School more than any other institution is responsible for the down grading of visual thinking. Most educators are not only disinterested in visual thinking, they are hostile toward it and regard it as childish, primitive, and prelogical. They emphasize information stored in proper categories with little thought to connecting it with the real world. This is counter to what research shows: teachers whose instruction has students make more mathematical connections at all levels of representation (concrete, iconic, & abstract) perform better than those with less experiences.

Six Modes of Visual Learning (developed by the Polaroid Education Program)

1. Exploring: the use of objects or pictures to identify and differentiate properties and their relationships to other properties. Similarities, differences, longer, shorter, tall, short, big, small, same, different, discriminate between letter and number shapes b, d, 2, 5.
2. Recording: sketching, drawing, photographing, video-recording. Can develop the ability to sequence events in time, understand transformations, and improve memory through chaining of events. The ability to put together visual memories or actual recordings is directly tied to telling and interpreting stories in all forms.
3. Expressing: acting, sketching, drawing, photographing, and video-recording to express feelings and emotions. The ability to identify emotions and to display different emotions in a variety of forms. Help interpret stories in all forms including forms beyond visual to include text, punctuation, sounds, and colors.
4. Motivating: Celebrating student's accomplishments. Verbal encouragement, specific praise, and social recognition by students as well as teachers. Labeling students' creations and preserving them so that they are inviting to students over time and give legitimant recognition to the creators.
5. Communicating: interpret stories from different points of view and create their own stories by acting, sketching, drawing, photographing, and video-recording.
6. Imagining and Creating: speculate and create alternative ideas and events to include in drama, sketches, drawings, photographs, and videos. Telling alternative endings to stories, interpreting what a story looks like and create the actions and images in a variety of mediums.
