
Digital Portfolio plus a
White paper – a 5-10 page (double-spaced)
persuasive review of some aspect of mind
mapping, i.e., scripting MM in CSCL, MM as
an artifact, etc. [Based on your intuition,
describe how a MM can work, this is your
first iteration of a “solution”. The White
papers is a “soft sell” for your “solution” that
describes the problem (90% of the
document) and then states clearly how your
solution solves the problem (10%). Avoid
straw man arguments.]

If you are interested…

Manuscript for presentation – I hope
that we can publish this experience, i.e.,
based on several projects we will do,
together we formulate questions, collect
and analyze data, write… (this will likely
go beyond the workshop time frame and
is also more open-ended)
For example:
How does interaction develop/evolve in online collaborative mind
mapping?
What scripts can support online collaborative mind mapping?

Concept map – diagrams indicating interrelationships
among concepts and representing conceptual
frameworks within a specific domain of knowledge
(vanBoxtel)
contrast
Concept map – a visual set of nodes and arcs (a network
representation) that embodies the relationships among
the set of concepts. Also called knowledge maps,
mindmaps, semantic maps (Turns, et al.).
Nodes – terms/complexes/concepts (usually nouns,
things, examples, ideas, categories, people, locations…)
Links (arcs) – lines connecting nodes, usually labeled
with a relationship term (usually verbs)
Propositions – node-link-node combinations, also called
“soup” (ketti) by IHMC
Turns, Atman, & Adams, 2000

Yellow stickies!! Pencil and paper may
be best for your classroom
Software – PowerPoint is pretty good
Inspiration is good but expensive

Project 1 and 2




We will experiment with two online collaboration
approaches
Project 1 is a synchronous concept map
collaboration using Cmap tools software
Project 2 is an asynchronous concept map
collaboration using PowerPoint software and email
But next, we will try brainstorming with Cmap tools to
become familiar with the tools and process before
setting up Project 1

Mindmap activity…
First Mind map CSCL roles…




Starter: You work as a discussion moderator. Your assignment is to engage your
group members to the discussion by asking questions and commenting. And if the
wrapper makes small summaries during discussion you can utilize his or her work to
raise new questions. Active participation in the discussions is essential.
Wrapper: Your assignment is to sum up the discussion. If you think it is easier you
can summarize frequently and weave ideas together. For example, if five participants
of your group are having a discussion about collaborative and co-operative learning
you can summarize their main points during the discussion. An alternative way is to
sum up the discussions in the end of article-videoclip task (and the last course
assignment). Please overview your group's discussions and make a brief summary
of the main topics. Active participation in the discussions is essential.
Group member: Your assignment is to participate actively into discussions by asking
questions making comments and stating arguments. You are expected to be a critical
inquirer.
Evaluator (an optional role): You are required to evaluate your group's work during
the course. Please focus on the group interaction and group dynamics, for example
how the starters, wrappers and group members performed during the discussions
and last course assignment. The tutors inform you when to perform evaluations.
Notice that you are also a deputy starter and a deputy wrapper if the originally
named persons are not available. If you are called to work as a starter or wrapper
please see the instructions given above. The role of evaluators are used only if you
have not had a role of starter or wrapper during this course.

Group Task Roles
Initiator-contributor. Proposes new ideas or approaches to group problem solving; may
suggest a different approach to procedure or organizing the problem-solving task
Information seeker. Asks for clarification of suggestions; also asks for facts or other
information that may help the group deal with the issues at hand
Opinion seeker. Asks for clarification of the values and opinions expressed by other
group members
Information giver. Provides facts, examples, statistics, and other evidence that pertains
to the problem the group is attempting to solve
Opinion giver. Offers beliefs or opinions about the ideas under discussion
Elaborator. Provides examples based on his or her experience or the experience of
others that help to show how an idea or suggestion would work if the group accepted
a particular course of action
Coordinator. Tries to clarify and note relationships among the ideas and suggestions that
have been provided by others

Novak

Novak says “Concept maps were first developed in our
research program in 1972 as a way to represent
changes in children’s understanding of science
concepts over the 12-year span of schooling. We were
using modified Piagetian clinical interviews to assess
changes in their knowledge over time, but we found the
interview transcripts were too difficult to analyze for
changes in specific aspects of the children’s
knowledge. Instead we prepared concept maps from
the interviews.”

Concept maps contains
propositions
These propositions
scores are generally
considered to be valid
and reliable measures
of science content
knowledge organization
(Ruiz-Primo, Schultz,
Li, Shavelson, CREST
in California. . .).
40
e.g.,…



Rye and Rubba (2002) reported that traditional
concept map scores were related to California
Achievement total test scores (r = 0.73). (Note
that Crocker and Algina say that validation
coefficients rarely exceed r=0.50.)
Concept maps (cognitive maps, concept maps)
may be an appropriate approach for assessing
structural knowledge (Jonassen, Beissner, &
Yacci, 1993).
For example, concept maps have been used to
visualize the change from novice to expert.
41
Scoring Concept Maps

Traditionally, concept maps are scored by
teachers or trained raters using scoring rubrics
(e.g., Lomask’s rubric)


Although this marking approach is time
consuming and fairly subjective, map scores
usually correlate well with more traditional
measures of science content knowledge
(multiple choice, fill-in-the blank, and essays)
Complex scoring rubrics decrease the concept
map score reliability (so keep scoring simple)
42
Scoring Concept Maps
C3 describes our automatic system for scoring
concept maps:
collect –>convert –> compare
1.
2.
3.
Collect raw map data
Convert raw data into a mathematical network
representation
Compare the mathematical network
representation of two maps (e.g., student to
teacher, student to expert, student to student)
43
1. Collect raw data



What raw data can a computer “extract” from
a concept map?
Term counts – in open-ended maps, count
required terms included
Propositions – a link connecting two terms
and a link label
Associations – geometric distance between
pairs of terms. Small values indicate
stronger relationship.

Link and distance


Link data (propositions) – are the common way
to compare/assess concept maps
Distance data – not common, based on James
Deese’s (1965) ideas on the structure of
association in language and thought, cardsorting task approaches (Vygotsky in Luria,
1979, Miller, 1969), Kintsch and Landauer’s
ideas on representing text structure, and
neural network methods (Elman, e.g., 1995)

Selecting terms


Selecting important terms (and their
synonyms) is a critical step (for example,
singular value decomposition in LSA
derives terms). We use an expert(s) to
determine terms.

2. Convert raw data into scores



Currently, we use a data reduction and comparison
approach called Pathfinder network representation
(PFNet, Schanveldt, 1990). Our future research will
consider additional approaches, such as MDS and
data-mining. http://interlinkinc.net/Pathfinder.html
PFNets describe the least weighted path to connect the
terms
Scores are established by comparing the participant’s
PFNet to a referent (expert) PFNet, and calculating the
number of common links (the intersection)

Relational condition, participants were required
to “unscramble” sentences (following Einstein,
McDaniel, Bowers, & Stevens, 1984) in one
paragraph in each of the five sections or about
20% of the total text content
Proposition-specific condition (following
Hamilton, 1985), participants answered three
or four adjunct constructed response questions
(taken nearly verbatim from the text) provided
at the end of each of the five sections, for a
total of 17 questions covering about 20% of the
total text content (no feedback was provided).


Pathfinder is a mathematical approach for representing
and comparing networks, see:
http://interlinkinc.net/index.html
Pathfinder data reduction is based on the least weighted
path between nodes (terms), so for example, Deese’s
171 data points become 18 data points. Only the salient
or important data is retained.
Pathfinder PFNet uses, for example:

MDS and PFNet data reduction


MDS uses all of the data points to
reduce the dimensions in the
representation, and so may be
improperly driven by noise in the data or
by unimportant data points
Pathfinder uses only the most important
data
94

in your research area (Finnish and

generative learning strategies
+
++
Generative learning (Jonassen, 1988)
 recall - repetition, rehearsal, review, mnemonics
 integration - learner paraphrases, generates
questions, generates examples
 organization - learner analyzes key ideas by creating
headings, underlining keywords, outlining,
categorizing (i.e., invent table categories, populate a
table with existing ideas)
 elaboration - generate mental images, create
physical diagrams, sentence elaboration (i.e., invent
stuff to fill cells in a table)

I just "think" systemically and "ndimensionally" on paper, with imagery…
My essential skill is simply--If you can explain it to me, I can draw a picture of it.
It doesn't matter if it's something totally new to me, if you can make a coherent
explanation, and let me understand it. I can "visualize it" and make a picture

Experts-in any discipline), let them do a "data-dump" and put a sketch in their

and "do-able" condition.
