Moodle
Moodle (abbreviation
for Modular Object-Oriented
Dynamic Learning Environment) is a free source e-learning software platform,
also known as a Course Management System, Learning Management
System, or Virtual Learning
Environment (VLE). As of October 2010 it had a user base of 49,952
registered and verified sites, serving 37 million users in 3.7 million courses.
Moodle was
originally developed by Martin Dougiamas to help educators create online
courses with a focus on interaction and collaborative construction of content,
and is in continual evolution.
The Moodle
project comprises several distinct but related elements, namely
§ Moodle Pty Ltd (also
known as Moodle Headquarters or the Moodle Trust, based in Perth, Western Australia), an Australian company who perform the majority of the
development of the core Moodle platform.
§ the Moodle Community, an open network of over one million
registered users who interact through the Moodle community website to
share ideas, code, information and free support. This community also includes a
large number of non-core developers, with Moodle's free source license and
modular design allowing any developer to create additional modules and features
that has allowed Moodle to become a truly global, collaborative project in
scope.
§ the Moodle Partner network, who form the commercial arm
of the Moodle environment and who provide the bulk of the funding to Moodle Pty
Ltd through the payment of royalties.
Features
Moodle has
several features considered typical of an e-learning platform, plus some
original innovations (like its filtering system). Moodle is very similar to a learning
management system. Moodle can be used in many types of environments such as in
education, training and development, and business settings.
Some typical
features of Moodle are:
§ Assignment submission
§ Discussion forum
§ Files download
§ Grading
§ Moodle instant messages
§ Online calendar
§ Online news and announcement (College and course level)
§ Online quiz
§ Wiki
Developers can
extend Moodle's modular construction by creating plugins for specific new
functionality. Moodle's infrastructure supports many types of plug-ins:
§ activities (including word and math games)
§ resource types
§ question types (multiple choice, true and false, fill in the
blank, etc)
§ data field types (for the database activity)
§ graphical themes
§ authentication methods (can require username and password
accessibility)
§ enrollment methods
§ content filters
Many
freely-available third-party Moodle plugins make use of this infrastructure.
Moodle users
can use PHP to
author and contribute new modules. Moodle's development has been assisted by
the work of open source programmers. This has contributed towards its
rapid development and rapid bug fixes.
By default
Moodle includes the TCPDF library
that allows the generation of PDF documents
from pages.
Deployment
Users can
install Moodle from source, but this requires more technical proficiency than
other automated approaches such as installing from a Debian package,
deploying a ready-to-use TurnKey Moodle
appliance or using the Bitnami installer.
Some free
Moodle hosting providers allow educators to create Moodle-based online classes
without installation or server knowledge. Some paid Moodle hosting providers
provide value-added services like customization and content-development.
Interoperability
Moodle runs
without modification on Unix, Linux, FreeBSD, Windows, Mac OS X, NetWare and any other systems that support PHP and
a database, including most webhost providers.
Data goes in a
single database. Moodle version 1.6 could use MySQL or PostgreSQL.
Version 1.7, released November 2006, makes full use of database abstraction so
that installers can choose one from many types of database servers such as Oracle and Microsoft SQL Server.
E-learning
systems can have many dimensions of interoperability. Moodle's interoperability
features include:
§ enrollment, using IMS
Enterprise among other standard methods, or by direct interaction with
an external database
§ quizzes and quiz questions, allowing import/export in a
number of formats: GIFT (moodle's own format), IMS QTI, XML and XHTML (NB although export works very well, import is currently not
complete). Moodle provides various types of
questions - Calculated, Description, Essay, Matching, Embedded Answers,
Multiple Choice, Short Answer, Numerical, Random Short-Answer Matching,
True/False.
§ integration with other Content Management
Systems such as Drupal or Postnuke (via third-party extensions)
§ syndication, using RSS or Atom newsfeeds -
external newsfeeds can be displayed in a course, and forums, blogs, and other
features can be made available to others as newsfeeds.
Moodle also has
import features for use with other specific systems, such as importing quizzes
or entire courses from Blackboard or
WebCT. These import tools are not, however perfect. At the time of writing (Feb
2010), Moodle will not import Blackboard courses due apparently to some change
in php code-releases.
Background
Origins
Martin
Dougiamas, who has graduate degrees in computer science and education, wrote the first version of Moodle. Dougiamas started a Ph.D. to
examine "The use of Open Source software to
support a social
constructionist epistemology of teaching and learning within
Internet-based communities of reflective inquiry". Although how exactly
social constructionism makes Moodle different from other eLearning platforms is
difficult to show, it has been cited as an important factor by Moodle adopters. Other
Moodle adopters, such as the Open University in the UK, have pointed out that
Learning Management Systems can equally be seen as "relatively
pedagogy-neutral".
Pedagogical approach
The stated
philosophy of Moodle includes a constructivist and social
constructionist approach to education, emphasizing that learners (and not
just teachers) can contribute to the educational experience. Moodle supports an
outcomes-oriented learning environment.
Origin of the name
The acronym Moodle stands for Modular Object-Oriented Dynamic Learning Environment (in
the early years the "M" stood for "Martin's", named after
Martin Dougiamas, the original developer). As well as being an acronym, the
name was chosen because of the dictionary definition of Moodle and
to correspond to an available domain name.
"Moodle"
is a trademark in many countries around the World registered to Martin
Dougiamas. Only Moodle Partners may legally use the trademark to
advertise any Moodle-related services such as hosting, customization, training
and so on.
Moodle statistics and market share
§ By 5 October 2010, Moodle had a user-base of 54,311
registered sites with 43,616,413 users in 4,583,237 courses in 212 countries
and in more than 75 languages.
§ The site with the most users, moodle.org, has 63 courses and
838,109 users. Following a £5 million investment in 2005, The Open University,
UK is the second-largest Moodle deployment by user-base, with 607,536 users and
4,731 courses. A comprehensive list of the top ten Moodle sites (by courses and
by users) is maintained at moodle.org.
Development
Moodle has
continued to evolve since 1999 (since 2001 with the current architecture).
Major improvements in accessibility and
display flexibility were developed in 1.5. The current version
is 2.0, which was released in November, 2010. It has been translated into 82
different languages.
Not having to
pay license fees or to limit growth, an institution can add as many Moodle
servers as needed. The Open University of the UK is currently building a
Moodle installation for their 200,000 users. It is often known for individual
departments of institutions to use the unlimited feature, such as the maths
department of the University of York.
The development
of Moodle continues as a free software project supported by a team of
programmers and an international user community, drawing upon contributions
posted to the online Moodle Community website that encourages debate and
invites criticism.
Users can
freely distribute and modify the software under the terms of the GNU General Public
License version 2 or any later version.
