tool
What is Open Source?
Licensed software that can be freely
distributed
License allows users to modify and
adapt to their own needs
May have restrictions on redistribution
Community of developers and users
Open Source Programs
that We Already Know and Love
Linux
sendmail
Apache
Tcl/Tk
Perl
Emacs
MySQL
PHP

In fact, a lot of the
internet runs on open
source software!
The Vision
Institutions sharing open source tools
Basic open source frameworks that accept
tools and integrate them with:

Campus SIS, Portal, Authentication System, File
Servers, Calendar, etc.
Modular, interoperable, open source tools
Rich set of open source tools to support:

discussion, quizzes, learning communities,
problem sets, project-based learning, syllabi,etc.
The Need-Control of the
Campus Learning Tools
to integrate learning tools into campus infrastructure

SIS, file servers, authentication, email, portal, calendar
to modify tools to fit pedagogical methods of faculty
to add new tools requested by faculty
to develop content with faculty using learning tools.
to always retrieve faculty content - content is NEVER
locked in proprietary formats
to have tool continue even if original developer “dies”
Why an Open Source CMS?
Port software to your environment: no longer
restricted by vendor requirements
Modify and expand software to meet your needs
and integrate with existing campus systems
Easy to integrate features, customizations, and
fixes developed by other users
Work with a common technical framework to
share reusable learning objects
More Reasons Why
Open standards allow interoperability of
applications and services
Non-proprietary data formats mean
easier conversion to or from the system
Reduced acquisition costs: no need to
pay for evaluation software, and can
take as long as you need
You don’t have to pay for upgrades!
But that doesn’t mean you get
something for nothing….
Must have or develop internal expertise to manage
the system and development tools
Extensive customization may result in development
and support costs equal to or greater than the cost
of commercial software….
…but at least you have control: you’re no longer
dependent on vendors for upgrades and
integration
Recent History of Learning Tools
Hundreds of Course Management Systems and
Learning Tools with many as Open Source

Thelma Looms Listing at GWU
 160 with a few “free” from 98 to 02

THOT
 235 plates-formes e-formation, plates-formes e-learning
with 28 Open Source - current

EduTools Listing
 32 with 10 Open Source - current
Some Open Source CMS’s
Open Learning Management System - Dept of
Psych-Utah – Basic System
FLE3 Future Learning Environment –Helsinki
– Collaborative Knowledge Bldg
Moodle by Martin Dougiamas, Australia –
Week-by-week Courses
Some more Open Source CMS’s
CHEF –a full portal with research and
instructional support system
OnCourse - Indiana’s reworked CMS
CourseWork – Stanford’s 80% solution.
Supports lectures and seminars.
The History - Research and
Non-Education-Specific Apps
Blogs
Wikis
Collaborative Knowledge Building
Virtual Worlds for Chat
Structured Discussion
Content mixed with Tools
The History - Commercial and
Open Source Learning Tools
No standards
No modularity
Little collaboration among developers
Much redundancy
Some unique applications



collaborative knowledge building,
structured discussion,
problem-based learning
The History - Commercial and
Open Source Learning Tools
All are vertical apps leading to:

Much effort for Sys Admins


Much time for faculty


Many separate apps to maintain and integrate
Multiple student lists, Separate systems for
assessment, difficult to relate components
Much confusion for students
 Multiple sites, multiple passwords, no
integration between activities
What’s Needed
Standards – OKI, IMS
Organization for tech support & distribution

A Merlot++ for infrastructure tools??
User community

Many users helping each other
Development community

Several developers of tools using same framework
What’s Happening-Standards
OKI Collaboration of many universities,
funded by Mellon Foundation.
IMS

Content Packaging, QTI, etc. DTD’s
SCORM
What’s Happening - Open
Knowledge Initiative (OKI)
Collaboration of many universities, funded by
Mellon Foundation.
Goal


Define open architectural specifications to support the
development of educational software.
Provide a modular and extensible development
platform for building both traditional and innovative
educational applications while helping institutions
leverage existing infrastructure.
More information: http://web.mit.edu/oki
What’s Happening - OKI
Develop standard APIs for:

Common Services
 Authentication
 Authorization
 Database Connectivity
 Filing
 Logging


Class Info (student lists)
Assessment and Grades
What’s Happening - User
Groups & Distribution Support
Content

Merlot (Learning Object Sharing)
Content and Tools

LON CAPA and WebWork have user groups
CourseWork Evaluation at Denison &
other colleges
CHEF Workshops
Hewlett/Mellon looking at distribution
What’s Happening - Developers
starting to collaborate
First goal is to use each others’ tools in proofof-concept demonstrations
OKI users working together (It takes more
than APIs)

Evaluation for Open Source Release
5 Universities/colleges (already selected) are
setting up local server and testing.



They will report on features, admin issues,
compatibility with their campus systems.
Two have servers running with little assistance;
third needed help in setting up Tomcat
Denison University is evaluating CourseWork for
reporting to CLAC
Grant proposal submitted to Mellon Foundation
for support for outreach to liberal arts colleges
Changes will be made in open source version
based on evaluation.

Give flexibility to end user in features
available
Templates - Flexibility in the
layout of an assessment
All questions, responses, and feedback can be in
multiple media
Questions can be accessed randomly or restricted to a
fixed sequence with no returns to earlier questions
Instructor can allow students to bookmark questions
and return to them
Web pages can be configured to contain a single
question, a set of questions, or the full assessment
Number of submissions by each student can be fixed
or unlimited
Templates - Flexibility in
evaluation views and procedures
Instructor can select type of evaluation: comments (at
part, question, or assessment level) or scores
