WHAT IS A CONCEPT MAP?



A concept map is a hierarchical map, which shows the
relationship between a series of concepts.
Concept maps are visual/spatial representations of ideas
and their interrelationships.
“Nodes” or “cells” denote concepts.
Concepts are linked by arrows to form propositions, which
describe the relationship(s) between the concepts.

HOW TO CONSTRUCT A MAP


Define the “question” to be answered.
Identify the key concepts/ideas.
Rank the concepts/ideas from the most inclusive to the most
specific/least general.
Construct a preliminary map, with the most inclusive concepts at the
top of the map, and the least inclusive concepts at the bottom. Enclose
each concept in a box to create “nodes”
Link concepts/nodes using a combination of arrows and “linking”
words.
Combinations of concepts, i.e., two nodes and a link, define a
proposition.
Refine the map.
