4. About the value of visual representation
5. About the basic types of knowledge
6. About meaningful and mindful learning
7. Why knowledge integration is difficult but
essential
8. How to think about biogeocomplexity
In this short course,
you will also learn:
8. How to make and use a tag cloud diagram
9. How a set of micromaps can collectively form a
macromap
10. How an online DRAGON/GLOW knowledge base
consisting of concept maps could capture and
integrate the partners’ knowledge
11. How DRAGON/GLOW scientists could use others’
concept maps for problem solving & science
education
12. How to draw computer-based concept maps--and
even attach scientific papers, video clips, notes,
etc. to those maps
Visual Cognition
• Cognition = is the way we organize our thoughts
and make sense of the world.
• IQ test scores worldwide have risen dramatically
since 1918 on, but this have been masked by
score scaling. But scientist James R. Flynn (NZ)
noticed the biggest improvement has been on
the pattern completion and visual-spatial
thinking test items (“Flynn Effect”). This suggests
that we are increasing dependent on our visual
system to understand today’s world.
• This is why we are considering concept
mapping at this DELTA/GLOW Summit.

Scientific Concept
• Definition: a pattern or regularity that scientists have given
a word label—such as “wetland”
• Concepts can be real objects: gill, shrimp, seamount
• Concepts can be abstract ideas: ecosystem, supercontinent
• Concepts can be processes: rock cycle, ecosystem services
• Concepts can be properties: concentration, biodiversity, relief
• Concepts are what we scientists think with.
Learning a Concept
•
Concepts vary in hierarchical inclusiveness, such as:
vertebrate
bird athe basic level
crane
red-headed sarus crane
•
It takes a variety of examples for us to understand a
new concept well—to “see the pattern.”
•
Good tests of understanding a new concept are to :
(a) come up with an example not previously mentioned;
(b) sort a mixed set of objects or events into concept
categories.
Definition of a Concept Map
• A 2-dimensional, hierarchical, visual
representation of a domain of scientific
knowledge--consisting of linked concepts
and examples—useful for problem-solving
and instruction
• Based on the research of biologist Joseph
Novak at Cornell University (1979-present)

Why Use Novak’s Concept Mapping
Approach?
• There are many kinds of graphic organizers but
this type has been the subject of more than
1,000 research studies since 1979.
• This is the type most commonly used in science
instruction.
• There have been and continue to be
international research conferences on using this
type of map.
• Concept maps mirror how the brain organizes
information—hierarchically.
• Relationships are specified—unlike “mind
maps.”
• Examples anchor the map to the real world.
• Multimedia icon capability allows “drilling down.”
Science Terms
• Proposition—a knowledge claim that
connects two concepts (Cells contain
nuclei. Water acts as a solvent.)
Uniform itarianism
assu me s th at th e
Knowledge about a topic
consists of all the propostions
that a person knows about it .
Propositions can also be equations.

Putting in links on their maps.
Basic Kinds of Knowledge
• Declarative (content knowledge) *
• Procedural (process knowledge)
• Episodic (narrative knowledge)
• Concept maps are suitable for declarative
knowledge.
• Flow charts and cycle diagrams are suitable for
procedural knowledge.
• Illustrated text is suitable for narrative
knowledge.
• Construct—a higher-order concept that is
composed of several subconcepts (acceleration,
photosynthesis, bioturbation, blood diamond )

Scientific Language
• Principle—a useful generalization
(Archimedes’ Principle, Causality Principle,
Pascal’s Principle, Bernoulli’s Principle)
• Law—old term; a broad and important
principle (Hooke’s Law, Newton’s Laws, Law of
Superposition, Law of Parsimony, Cope’s Law)
• Theory—describes, predicts, explains a
large set of natural phenomena (atomic
theory, cell theory) Theories must be must be:
consistent, parsimonious, correctable,
empirically testable/verifiable, useful, and
progressive.

Scientific Thinking…
Based on shared presuppositions about nature
Uses reason and logic
Uses multiple methods
Power resides in the argument, not the person
No supernatural explanations are allowed
Is evidence-based and data-driven
May change over time = progress
Values careful, multiple observations
Values experimentation & replication
Must fit within the accepted scientific framework
Requires moving towards a global consensus
Requires domain-specific knowledge
Values theory-building

The Metaphor of the Net
• A net whose mesh is too coarse misses
catching the target species.
• A net whose mesh is too fine captures
both the target species and lots of trivial
ones.
• Therefore a concept map should display
only the key concepts--and those will
trigger recall of the supporting details.

Biocomplexity
• Biocomplexity (NSF, 2001) the complex
behavioral, biological, social, chemical,
and physical interactions of living
organisms (including humans) with their
environment. The subfield of biocomplexity
encompasses other domains such as
biodiversity and ecology.
• Example: The annual summer “Dead
Zone” of the Gulf of Mexico
A Scientific Issue with Many Facets

Biogeocomplexity
• We would like to expand the term
biocomplexity to biogeocomplexity by
counterbalancing the biological with the
geological components of complex scientific
issues.
• We see such issues characterized by emergent
properties, where the ensemble forces possess
capabilities that its individual agents lack.
• An oral example is: Sea Level Rise
• “When the sea level rises by 1 meter, many
provinces in the Mekong Delta will be
flooded.” Source: VietNamNet Bridge – The Climate Change

The Biggest Challenge for the
DRAGON / GLOW Partnership
•
•
•
The greatest challenge is communication, because
our sciences and regions have rarely interacted.
What causes this? Its called “moving out of your
comfort zone.” We scientists love to focus in and
understand some natural phenomenon--many of us
might spend the better part of a lifetime on one
subject. We can easily become the world’s expert. But
to move marginally outside our own science discipline
is often a daunting task.
Concept maps can provide a bridge across our
research specialties, across the great rivers and lakes,
across what is already known by some of us but not all
of us. Concept maps we make can offer a shared
visual portal into what we know collectively-- available
24/7 on the Web.
Two Kinds of Knowledge
To Be Captured on Maps
Explicit knowledge:
• can be expressed in words and numbers, and shared in
print and in presentations. *This has been the dominant
kind of knowledge in the West.
Tacit knowledge:
• is highly personal, experiential, and hard to formalize-making it difficult to communicate or share with others. It
can be (a) technical or (b) it can embody perceptions,
values, and ideals. It is best learned by apprenticeship or
“think-aloud” protocol. *This has been an important kind of
knowledge in the East.

Draw a Micromap of
your own Area of
Scientific Expertise (or Interest)
• Your top concept will be “Hao Chen’s Scientific
Expertise” or “Hao Chen’s Scientific Interest.”
• Include the field or fields of science you use in
your work.
• Include some important concepts you use in
your work.
• Include what you study and where you study it.
• We will offer you private help if you raise your
hand and tell us what you are trying to map.
• You will have an opportunity to post your map at
this Summit for all to see--if you agree.
Ready, Set, Go!
• Use the back side of the paper for your draft version—it
is normal to make revisions.
• Please print, instead of using handwriting.
• Use the ruler and the circle-form to make your map’s
lines and symbols.
• Try to limit your map’s size to a total of about 12-15
concepts and examples.
• Remember that every line needs to be labeled with
linking words.
• From top to bottom, move from “general” to “more
specific” concepts.
• Look for 1-2 possible cross-links you could insert on your
map.
• When done, your concept map should introduce us to
you and your work.
Later At this Summit Meeting…
• IF you brought your laptop computer with you,
go to http://cmap.ihmc.us/conceptmap.html
and download the free Cmap software.
• Try making your own computer-based concept
map. There are lots of “helps” on that web site.
• Try mapping your best research study.
• Try mapping the river or lake system that you
study, or that is the focus of your interest.
