Concept Maps
A way to demonstrate
understanding and seek new
knowledge
What Are Concept Maps?

Concept maps are graphical tools for
organizing and representing knowledge,
and seeking new knowledge.
What Do They Look Like?
Concept maps include:
 Concepts, usually enclosed in circles or
boxes of some type
 Relationships between concepts
indicated by a connecting line linking two
concepts.
 Words on the line, referred to as linking
words or linking phrases, specify the
relationship between the two concepts.

Propositions

The combination of two nodes and a
labeled line is called a proposition.


It is the basic unit of meaning in a concept
map
The simplest concept map would be two
concepts connected by a linking word to
form a proposition (Novak & Gowin,
1984, p. 15)

For example, “seeds grow into plants.”

Concept maps, then, purport to
represent some important aspects of a
person's declarative knowledge in a
content domain (e.g., physics).
What is a Concept?
We define concept as a perceived
regularity in events or objects, or records
of events or objects, designated by a label.
 The label for most concepts is a word,
although sometimes we use symbols such
as + or %, and sometimes more than one
word is used.

Propositions are statements about some
object or event in the universe, either
naturally occurring or constructed.
 Propositions contain two or more
concepts connected using linking words
or phrases to form a meaningful
statement.


Sometimes these are called semantic
units, or units of meaning.
Hierarchy

A characteristic of concept maps is that
the concepts are represented in a
hierarchical fashion
with the most inclusive, most general
concepts at the top of the map
 the more specific, less general concepts
arranged hierarchically below.

Cross-Links

Cross-links are an important characteristic of
concept maps.
 These are relationships or links between
concepts in different segments or domains of
the concept map.

Cross-links help us see how a concept in one
domain of knowledge represented on the map is
related to a concept in another domain shown on
the map.
New Knowledge

In the creation of new knowledge, crosslinks often represent creative leaps on
the part of the knowledge producer.
New Knowledge
These two features are important in the
facilitation of creative thinking:
 The hierarchical structure
 The ability to search for and
characterize new cross-links.

Clarifying
We may add specific examples of events
or objects that help to clarify the meaning
of a given concept.
 Normally these are not included in ovals
or boxes


They are specific events or objects and do
not represent concepts.
The Process

Brainstorming


Organizing


On a large sheet of paper, try to come up with an arrangement
(layout)
Linking


Spread out your concepts (Post-It® notes) on a flat surface so
that all can be read easily and, together, create groups and subgroups of related items.
Layout


identify facts, terms, and ideas that you think are in anyway
associated with the topic
Use lines with arrows to connect and show the relationship
between connected items.
Finalizing

convert the concept map into a permanent form that others can
view and discuss.
Context

It is important to begin with a domain of
knowledge that is very familiar to the person
constructing the map.
 Concept map structures are dependent on the
context in which they will be used.


Best to identify a particular problem or question that
one is trying to understand.
This creates a context that will help to
determine the hierarchical structure of the
concept map.

It is also helpful to select a limited domain of
knowledge for the first concept maps
The Focus Question
A good way to define the context for a
concept map is to construct a Focus
Question.
 A question that clearly specifies the
problem or issue the concept map
should help to resolve.


Every concept map responds to a focus
question, and a good focus question can
lead to a much richer concept map.
Beginning the Map
Given a selected domain and a defined
question or problem in this domain, the
next step is to identify the key concepts
that apply to this domain.
 Usually 15 to 25 concepts will suffice.

Parking Lots
We refer to a list of concepts waiting to
be added to a concept map as the
parking lot of concepts.
 The starting point for the construction of
the concept map can be a list of
concepts that the teacher wants to make
sure all students include in their map.

Parking lot of Ideas

We then start with the most general
concept and work toward the most
specific adding connecting arrows and
linking words.
Note: Not all the words in the parking lot were used,
and these are yet to be added.

What is a Good Concept Map

Accuracy and Thoroughness. Are the concepts and
relationships correct? Are important concepts
missing? Are any misconceptions apparent?
 Organization. Was the concept map laid out in a way
that higher order relationships are apparent and easy
to follow? Does it have a title?
 Appearance. Was the assignment done with care
showing attention to details such as spelling and
penmanship? Is it neat and orderly or is it chaotic and
messy?
 Creativity. Are there unusual elements that aid
communication or stimulate interest without being
distracting?
Seasons
“Why do we have seasons?”
 Only eleven concepts, properly
organized are needed to understand why
we have seasons,


One arrangement of these concepts is
shown in the Figure.
Proposition: Without the industrial chemical reduction
of atmospheric nitrogen, starvation would be rampant
in third world countries.
