Visualisation & Mapping
• Visuals long been used in academia and teaching for their associative and visual qualities.
• Maps…o make things easy to findo chart paths to get placeso show us where things are and how to get from one
place to the nexto link things togethero reveal how things are connected
Mind Maps
• One of most well known and simple ways of connecting ideas together
• Tony Buzan - 1970's• Realisation the mind responds extremely well to
colors, images, key words and associations • Diagram of connected items - 'free association'
Concept Maps
• More complex and powerful form of mind mappingo a collection of nodes, connected by lines that define
their relationship to one anothero sets out a network of things/ideas/items that are
related o a tree and branch like structure
• Pioneered by Joseph Novak
Concept Maps• Novak interested in understanding how humans learned
• Based on David Ausubel’s theorieso Ausbel’s work based on Jean Piaget's work on constructivism
most important single factor influencing learning is what the learner already knows
new knowledge consciously and deliberately added onto the old
• Graphically representing a person's knowledge of a concept, can better understand how it was accumulated
• Result = simple but powerful map of concepts, or “concept map”
Knowledge Mapping
• Human knowledge is built by linking things together
• Computer storage and retrieval is based on linking things together
• Maps link things together
• Operate on same principle: linking
Topic MapsTopic Maps combine all the preceding concepts: indexes, hyperlinking, visualization mapping, findability, etc.
Hyperlinking
• Technology-assisted mappingo computer equivalent of “associationism"o "an associative index" - Dr. Vannevar Bush
(1945)o Project Xanadu - Ted Nelson "hypertext"
(1963) www.xanadu.neto hyperlinks overcome the constraints of time,
space, geography, retrieval, etc.
