During the past couple of decades, computers and computer
software have had an increasing effect upon teachers and
teaching. Beginning with word processing, grading spreadsheets,
and computer-based tutorials, educational software has proliferated
to include authoring systems, content management systems,
and learning management systems (you may not recognize these
software categories, but chances are you’ve heard
the names of specific software programs like WebCT--a content
management system---or Macromedia Authorware, an authoring
system).
However, the purpose of this article is to briefly
outline several types of software you’ve probably never
heard of---software that, while not presently widespread in
education, possesses promise for teaching and learning. I’ll
briefly present five types of software:
• Collaboratory
• Digital Asset Management
• Concept Mapping
• P2P Collaboration
• Peer Review
COLLABORATORY SOFTWARE
The term “Collaboratory” has most often been used
to describe a room containing computer workstations with special
software designed to assist group decision-making processes
like brainstorming and consensus building. However, you don’t
necessarily need a specialized room in order to have a Collaboratory,
for new technologies like wireless networks and laptop labs
make it possible to turn any classroom or conference room
into a Collaboratory.
What kinds of software tools are used in a Collaboratory?
GroupSystems, a leading supplier of Collaboratory software
(http://www.groupsystems.com/demos/tools.htm), includes these
tools:
• Categorizer: Used to collect a list
of ideas, then categorize those ideas into logical groupings.
The group can brainstorm on one single list, or enter ideas
directly into the categories. Common uses include cause and
effect analysis; organizing lists of tasks; and simple brainstorming.
• Voting: Eight voting methods, including
a customizable point scale, make the voting process flexible
and powerful. Used to evaluate, make decisions, and build
consensus.
• Group Outliner: Used to generate and/or
organize ideas into a familiar hierarchical structure. Outlines
can be displayed in bulleted or numbered format. The leader
can distribute the whole outline to participants, or allow
them to work in subgroups. Common uses include action planning;
group writing; and process design.
• Topic Commenter: The leader enters a
list of topics and asks participants to comment on those topics.
Common uses include discussing strengths and weaknesses (SWOT
analysis) and focus group research.
• Alternative Analysis: Used to evaluate
a list of alternatives based on multiple criteria. Sophisticated
charting allows for in-depth analysis. Common uses include
evaluating job candidates; assessing risks; rating vendor
proposals; and evaluating options.
• Electronic Brainstorming: Used for simultaneous
and anonymous idea sharing on a specific question or issue.
Common uses include team building; broad or focused brainstorming;
and visioning or strategic planning sessions.
• Survey: Used to build, distribute, and
collect survey forms. Common uses include employee feedback
surveys; 360 performance reviews; and customer surveys.
How can Collaboratory software be used for teaching
and learning? Take brainstorming for example, where a class
generates ideas which are written down and then discussed
in turn. Typically, this process takes a lot of time. However,
with Collaboratory software, everyone types ideas into a single
shared document where each person can constantly see what
others are writing. The best ideas are selected via anonymous
voting, the pros and cons of each idea are quickly compiled,
and the highest-rated course of action is identified. Thus
the processes of generating ideas, evaluating possible solutions,
and selecting the optimal solution are completed much more
quickly---and with a full record of the process to boot! For
a teacher, the time saved could mean the difference between
including a brainstorming exercise in class or excluding it
for lack of time.
Another advantage is that Collaboratory software
allows for anonymous input, which can lessen the chance of
group members withholding good ideas, being reticent about
speaking frankly in front of the instructor, the discussion
being dominated by a few dominant personalities, or “groupthink”
(bad decisions resulting from attendees who decline to state
their reservations regarding a course of action that is either
popular or advocated by a powerful or vocal member of the
group). With anonymity, ideas can be judged upon their merits
rather than by who advocates them.
To see examples of how Collaboratory software
is used in education, see San Francisco State University’s
web page at http://cet.sfsu.edu/classrooms/collaboratory/colabteach.html,
where it is used by programs in Black Studies, Biology, Technical
Writing, History, and Social Work.
DIGITAL ASSET MANAGEMENT SOFTWARE
As computers get faster and hard drives get bigger, I seem
to accumulate more and more files, to the point that it’s
so hard to find anything on my computer. Sure, I use the Search
tool, but I vaguely wish for something, well, better.
But if I think I’ve got it bad, imagine
the plight at an advertising agency with dozens of artists,
each with thousands of files (it’s estimated that the
average person with a “creative” job spends 1/10
of his or her work hours dealing with file management). To
facilitate file sharing, agencies often keep files stored
on a central server that can quickly accumulate millions of
files! Often this leads to confusion, wasted time, even lost
files.
To cope, ad agencies and other companies with
a critical need to manage files have turned to a new breed
of software for digital asset management (DAM). DAMs view
digital assets as analogous to any other organizational asset
(e.g., computer hardware) and provide powerful database tools
for cataloging, storing, searching, and retrieving those assets.
Simple DAM software (I know, I chortle every
time I say that!) offers thumbnailing of pictures, image libraries,
and powerful indexing and keyword capabilities. Because you’re
searching keywords or pre-generated thumbnail pictures instead
of large files, even searches among millions of files are
lightning fast. Some even allow “natural language”
queries and have “anti-lawsuit” built-in digital
rights management to ensure compliance with copyrights. As
such products become more widespread and standardized, many
other software programs will likely become DAM-compatible;
for example, any digital clip art or pictures you buy will
come “pre-equipped” with hidden metadata that
facilitate their use by a DAM system.
For an instructor, a DAM program could save
time and frustration in searching for files, allow sharing
of PowerPoint slides among related presentations, and help
build a collection of answers to frequently-asked questions.
Most importantly, it could mean never losing another file!
Examples of DAM software aimed at workstation
users include Canto’s Cumulus (http://www.canto.com/),
WebWare’s ActiveMedia (http://www.webwarecorp.com/products_services_activemedia.html),
and eMotion’s CreativePartner (http://www.emotion.com/images/CreativePartner.pdf).
CONCEPT MAPPING SOFTWARE
Psychologists who study human cognition believe that our long-term
memories are functionally organized as connected webs of concepts
called “semantic nets”. Here’s an example:
picture a little circle with the word BIRD in it. Under that
circle are several other circles with ROBIN, SPARROW and OSTRICH
in them. Lines called “links” connect the lower
circles to the upper one. This represents that robins, sparrows,
and even ostriches are part of the larger concept of “birds”.
If you graphically represent this or similar
examples on a sheet of paper, it’s called a concept
map (the results tend to look a bit like souped-up organizational
charts). Concept maps offer the advantage of showing relationships
as well as facts; i.e., you not only see the intellectual
parts, you see how they fit together.
There’s a burgeoning movement in education
to teach students how to create and use concept maps. Perhaps
the best-known concept mapping software is Inspiration (http://www.inspiration.com/productinfo/Inspiration/index.cfm;
you can download a 30-day free trial from http://www.inspiration.com/freetrial/index.cfm?fuseaction=insp).
Inspiration can generate concept maps from outlines (or vice
versa),
A different method is used by CMap, concept
mapping software available from http://cmap.coginst.uwf.edu/
that is free for academic uses (download it at http://cmap.coginst.uwf.edu/download/cmapForm.html).
CMap is used not only to create concept maps, but also to
navigate, share, and criticize; that is, using CMap is a shared
activity. It consists of software that is downloaded and installed
on individual PCs along with servers to house the concept
maps. NASA has used CMap to capture a lot of knowledge in
order to prevent “brain drain” when experienced
rocket scientists retire.
P2P COLLABORATION SOFTWARE
Nearly everyone has heard of Napster and is somewhat familiar
with the debate regarding the downloading of MP3 music files
via the Internet. The type of software that makes such activities
possible is called “peer-to-peer” (P2P) software.
P2P software works by turning each user’s computer into
a miniature Internet server, so that while you’re browsing
other users’ shared files, they can browse yours. Such
a scheme means that files never reside on a central server
(which is what makes file sharing so slippery, legal wise).
However, while folks are familiar with the concept
of sharing music, video, or other files via P2P, not many
people are familiar with the possibilities P2P affords for
educational collaboration. Imagine a “Napster”
where instead of music files being shared, bits of data fly
back and forth between two or more students who are collaborating
on an assignment in Microsoft Word or PowerPoint. This collaboration
can involve the use of tools that create outlines, word process
documents, share pictures, allow users to “chat”
via text or voice, synchronize documents, schedule calendar
events, etc.
Sound cool? It did to Ray Ozzie, the creator
of Lotus Notes, when he founded Groove Networks in October
1997. Groove, found at www.groove.net, sells P2P Collaboration
software to businesses. However, they offer a free version
of the Groove software for individuals. After downloading
and installing the software, you create a user account and
then create one or more “shared spaces” in which
to work. Browse a menu of tools, add the ones you want to
your shared space, and you’re ready to invite someone
over to collaborate!
PEER REVIEW SOFTWARE
Speaking of collaboration, collaborative learning is currently
a “hot” buzzword in education. Essentially, it
means teamwork. Someone must have noticed that even though
we tend to punish students for “not working independently”
throughout school, these same students graduate and enter
job environments where most work takes place in teams!
Peer review is a form of collaboration that
involves students evaluating students. Often, an instructor
provides a rubric whose specific instructions provide a framework
for the evaluation and increase the reliability of students’
ratings. An interesting twist on peer review is calibrated
peer review. As you can imagine, some students are better
peer reviewers than others. Wouldn’t it be nice if everyone’s
opinion “counted”, but the opinions of better
judges somehow counted more? That’s what calibrated
peer review is all about.
UCLA has created a web-based program called
CPR for calibrated peer review (see http://cpr.molsci.ucla.edu/).
An instructor creates (or borrows from the CPR library) several
“calibration” essays, and then creates a series
of evaluation questions for the essays along with his/her
answers to those questions. A student entering the system
first reads and rates the calibration essays. If the student’s
ratings are similar to the instructor’s, then that student’s
“calibration” is high and their opinions are more
highly weighted. After calibration, the system randomly assigns
several classmates’ papers for rating, and finally the
student rates his or her own paper. It’s a “win-win”---CPR
allows instructors to give frequent writing assignments without
increasing grading workload, and students learn from critiquing
each other’s (and their own) work.
By the way, Turnitin.com, the leading detection
service for academic plagiarism (www.turnitin.com, has recently
added peer review capabilities to its service as well.
