Graphicacy is defined as the ability to understand and present information in the form of sketches, photographs, diagrams, maps, plans, charts, graphs and other non-textual formats. [1]
The word graphicacy was coined by geographers William Balchin and Alice Coleman [2] as a characterisation of visuo-spatial and cartographic abilities, "the communication of spatial information that cannot be conveyed adequately by verbal or numerical means", including the whole field of graphic arts and much of geography, cartography, computer-graphics, and photography. The word "graphicacy" was chosen by analogy with literacy, numeracy and articulacy. [3]
Interpretation of graphics is loosely analogous to the process of reading text, while generation of graphics is the counterpart of writing text. However, text and graphics are based on very different symbol systems. For example, whereas text is structured according to formal organisational rules that apply irrespective of the content, this is not the case for graphics. With text structure, the units of information (words) are expected to be organised according to broad conventions (such as being sequenced in orderly rows starting from top left and progressing down the page). However graphics are not subject to a similarly stringent set of structural conventions. Instead, it is the content itself that determines the nature of the graphic entities and the way they are arranged. For example, the form and spatial arrangement of the items that comprise the actual subject matter being represented in the graphic are used as the basis for the graphic entities and structure that are displayed in the graphic. This is not the case with written text where the words and their arrangement bear no resemblance to the represented subject matter. Because of these and other fundamental differences between text and graphics, the processes involved in comprehension and production of graphics are distinguished from those involved in comprehension and production of text.
The concept of graphicacy acknowledges the characteristic features of graphic information that distinguish it from other forms of representation such as verbal and numerical information. Separating graphicacy from literacy and numeracy delineates the distinctive and complementary types of contributions that graphics, words, and numbers each make in human communication.
The interpretative components of graphicacy skills are relevant in the increasing range of situations where graphics carry the primary responsibility for communication. Early recognition of the importance of graphicacy came from disciplines such as geography, science and mathematics in which graphics play a key role. Educators in these and similar disciplines have become increasingly concerned with the capacities of students to comprehend information presented by way of graphics.
The interpretation of certain types of graphics can sometimes be very challenging. In addition, it is thought[ who? ] that graphicacy skills are largely learned rather than innate and that a viewer's capacity to interpret particular types of graphics is related to their background knowledge, in particular knowledge about the specific graphic system used to depict the subject matter, and knowledge about the subject matter that is depicted in the graphic. Severe deficiencies in either of these aspects of background knowledge may prevent a viewer from comprehending a graphic.
There are some fundamental differences between written text and a graphic representation. For example, a brief explanation of the structure of a bowstring arch bridge may read:
Spanning the river is the bridge’s arch structure with its ends carried by abutments on each bank. The deck of the bridge is suspended by struts attached to the arch and runs between the banks. Each end of the deck is connected to the arch's legs.
The main items mentioned, extracted and arranged in their order of mention in the text, would read:
River; Bridge; Arch; Ends of arch; Abutments; Banks; Deck; Bridge; Struts; Arch; Banks; Ends of deck; Arch legs
The signs used to represent parts of the bridge in words are very different from the signs used in the picture of the bridge. Furthermore, the same items (such as bridge, arch, and banks) are often mentioned more than once in the text version, due to the constraints of text as a representational system. However, in a graphic of this bridge, such information would only need to appear once. The arrangement of these items is also different in the text from what it would be in a graphic. When compared with the order of mention in the text with this depiction, the text is not arranged in a way that would directly map onto the bridge, but presents the bridge's components in a linear sequence that gives no visual indication of the bridge's structure.
Information design is the practice of presenting information in a way that fosters an efficient and effective understanding of the information. The term has come to be used for a specific area of graphic design related to displaying information effectively, rather than just attractively or for artistic expression. Information design is closely related to the field of data visualization and is often taught as part of graphic design courses. The broad applications of information design along with its close connections to other fields of design and communication practices have created some overlap in the definitions of communication design, data visualization, and information architecture.
Graphics are visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone, to inform, illustrate, or entertain. In contemporary usage, it includes a pictorial representation of data, as in design and manufacture, in typesetting and the graphic arts, and in educational and recreational software. Images that are generated by a computer are called computer graphics.
Numeracy is the ability to understand, reason with, and to apply simple numerical concepts. Basic numeracy skills consist of comprehending fundamental arithmetical operations like addition, subtraction, multiplication, and division. For example, if one can understand simple mathematical equations such as 2 + 2 = 4, then one would be considered to possess at least basic numeric knowledge. Substantial aspects of numeracy also include number sense, operation sense, computation, measurement, geometry, probability and statistics. A numerically literate person can manage and respond to the mathematical demands of life.
Visualization or visualisation is any technique for creating images, diagrams, or animations to communicate a message. Visualization through visual imagery has been an effective way to communicate both abstract and concrete ideas since the dawn of humanity. Examples from history include cave paintings, Egyptian hieroglyphs, Greek geometry, and Leonardo da Vinci's revolutionary methods of technical drawing for engineering and scientific purposes.
Infographics are graphic visual representations of information, data, or knowledge intended to present information quickly and clearly. They can improve cognition by utilizing graphics to enhance the human visual system's ability to see patterns and trends. Similar pursuits are information visualization, data visualization, statistical graphics, information design, or information architecture. Infographics have evolved in recent years to be for mass communication, and thus are designed with fewer assumptions about the readers' knowledge base than other types of visualizations. Isotypes are an early example of infographics conveying information quickly and easily to the masses.
Visual literacy is the ability to interpret, negotiate, and make meaning from information presented in the form of an image, extending the meaning of literacy, which commonly signifies interpretation of a written or printed text. Visual literacy is based on the idea that pictures can be "read" and that meaning can be through a process of reading.
Reading comprehension is the ability to process text, understand its meaning, and to integrate with what the reader already knows. Fundamental skills required in efficient reading comprehension are knowing meaning of words, ability to understand meaning of a word from discourse context, ability to follow organization of passage and to identify antecedents and references in it, ability to draw inferences from a passage about its contents, ability to identify the main thought of a passage, ability to answer questions answered in a passage, ability to recognize the literary devices or propositional structures used in a passage and determine its tone, to understand the situational mood conveyed for assertions, questioning, commanding, refraining etc. and finally ability to determine writer's purpose, intent and point of view, and draw inferences about the writer (discourse-semantics).
Geovisualization or geovisualisation, also known as cartographic visualization, refers to a set of tools and techniques supporting the analysis of geospatial data through the use of interactive visualization.
Educational animations are animations produced for the specific purpose of fostering learning. It is associated with educational technology with the way it supports teaching and learning through the use of technological tools to facilitate learning and to improve performance.
The visual language is a system of communication using visual elements. Speech as a means of communication cannot strictly be separated from the whole of human communicative activity which includes the visual and the term 'language' in relation to vision is an extension of its use to describe the perception, comprehension and production of visible signs.
Graphic communication as the name suggests is communication using graphic elements. These elements include symbols such as glyphs and icons, images such as drawings and photographs, and can include the passive contributions of substrate, colour and surroundings. It is the process of creating, producing, and distributing material incorporating words and images to convey data, concepts, and emotions.
Alice Mary Coleman is emerita professor of geography at King's College London. She is noted for directing the 1960s Second Land Use Survey of Britain and for analyses of land use planning and urban design which have influenced the design of residential developments since the 1980s.
Reading is the process of taking in the sense or meaning of letters, symbols, etc., especially by sight or touch.
The social sciences are the sciences concerned with societies, human behaviour, and social relationships.
Multimodality is the application of multiple literacies within one medium. For example, understanding a televised weather forecast (medium) involves understanding spoken language, written language, weather specific language, geography, and symbols. Multiple literacies or "modes" contribute to an audience's understanding of a composition. Everything from the placement of images to the organization of the content to the method of delivery creates meaning. This is the result of a shift from isolated text being relied on as the primary source of communication, to the image being utilized more frequently in the digital age. Multimodality describes communication practices in terms of the textual, aural, linguistic, spatial, and visual resources used to compose messages.
Professor Tom Lowrie was appointed a Centenary Professor at the University of Canberra, Australia, in 2014. He has an established international research profile in the discipline area of STEM education and mathematics education.
The Programme for the International Assessment of Adult Competencies (PIAAC) is a worldwide study by the Organisation for Economic Co-operation and Development (OECD) in 24 countries of cognitive and workplace skills. The main aim is to be able to assess the skills of literacy, numeracy and problem solving in technology-rich environments, and use the collected information to help countries develop ways to further improve these skills. The focus is on the working-age population. The first data was released on October 8, 2013. A new PIAAC survey is expected to be published in 2021/2022.
Graph literacy is the ability to understand information that presented graphically, which are including general knowledge about how to extract information and make inferences from different graphical formats. Although related, graph literacy is distinct from other forms of literacy in the sense that it relates more specifically to one's ability to obtain meaning from information presented graphically. It can include the storage of mental representations in long-term memory, knowledge about the properties of different types of formats, and procedures to interpret them. However, similar to other types of literacy, higher graph literacy is associated with higher education levels and suggests that developing the skills required to interpret graphical information requires knowledge that is acquired through formal education and experience.
Education graphics, or edugraphics, are graphic visual representations of educational information intended to simplify social-cultural content, communication-related content, linguistic content, etc. The use of rich visual content improves cognition, as the students comprehension is enhanced when both visual and text-based cues are combined.
William George Victor Balchin was a British geographer. He was noted for original research in geology and significant contributions to geography, and for establishing the academic concept of graphicacy.
