MotivationMotivation
During the last decade: ◦ … an enormous expansion of available knowledge◦ …a clear demand for new techniques to enhance
educational procedures ICTs are facilitating the use of e-learning
environments and standards. Programs and courses designed back in 1998 need
to be revisited to follow developments in:◦ online learning◦ continuing medical education◦ global education◦ social computing (Web 2.0)◦ sharing teaching material etc

AAim of thim of thee paper paper
to show the approach we have followed in properly shaping our courses in Medical Informatics by using:◦ open e-learning platforms/environments◦ educational standards◦ enriched student interaction and participation
through Web2.0 technologies To demonstrate an example of a module on

Technical conditions for the Technical conditions for the development of web-based development of web-based coursescourses Various educational platforms support web-based courses
and perform as Learning Management Systems (LMS) that enable the management of e-learning courses
LMS standards are used to ensure interoperability and transfer of courses between platforms.
The Sharable Content Object Reference Model (SCORM) by ADL is a standard that adopts specific requirements to enable interoperability, accessibility, reusability, sequencing between learning objects.
SCORM is embraced by a large number of institutions and corporations
Several studies propose extensions to SCORM metadata to enhance sequencing rules, usability, adaptability, assessment metadata

SCORMSCORM ((Sharable Content Object Reference Sharable Content Object Reference ModelModel) ) Consists of small, distributable learning
entities (Sharable Content Objects (SCOs)) SCO’s are
◦ Small in size◦ Reusable◦ Provide solid autonomous learning material but
also in combination with others The combination of SCO’s leads to:
◦ An educational unit◦ A complete course◦ A training field

Evaluation stepsEvaluation steps
Students’ evaluation in two stages. 1st Phase:
◦ students were asked to complete an anonymous questionnaire emphasising merely on the use of Web 2.0 tools.
◦ The Moodle system lead the logged-in students to an external web site powered by another open source source survey tool, namely, “PhP Surveyor”, so as to maintain anonymity.
2nd stage:◦ students were asked to evaluate the whole course ◦ using a dedicated, home made, evaluation software,
specifically developed for course evaluation purposes within the postgraduate program of the Medical School at AUTH.

Gross Evaluation results IGross Evaluation results I
1st Phase:◦ Evaluation of the results indicates that students
were quite satisfied by this approach, and were happy with the collaboration opportunities offered to them.
◦ Most of them admitted that they were tempted to “read what others have contributed in their own personal blogs” (which by the way were given public access to the enrolled students).
◦ they believed that they found the student collaboration opportunities offered by the system tools quite useful and enhancing the overall learning process.

Evaluation Results IEvaluation Results I
The approach has been evaluated within our post-graduate Medical Informatics course to medical students.
Active student involvement is sought through participating in discussion forums and wikis/blogs, thereby fulfilling some of the learning outcomes set by the educators.

Discussion IDiscussion I
Increased student liking for the course… Increased interaction and participation Educator may control activities through
Moodle Care must be taken in separate activities:
◦ Need small groups of people◦ Many blog existences may confude students◦ Need structured blogs◦ Wiki updates may confuse people◦ Need semantic wikis

Discussion IIDiscussion II
Learning Objects, as independent units of educational material targeting to specific training needs, constitute one of the main research topics in the e-learning community.
Many research initiatives in the field concern the issue of LOs’ reusability, but not within the Medical Informatics community.
It is only recently that such efforts have appeared, geared by MedBiquitous dedicated to advancing healthcare education through technology standards.

“Podcasting’s essence is about creating content (audio or video—vodcasts) for an audience that wants to listen when they want, where they want, and how they want.”*
Advantages:◦ Listen on your computer or download to portable MP3
players and listen on the move/anywhere (perfect for the busy health professional). But audio and video files can be large in size; users must have sufficient bandwidth to download them.
◦ Support for auditory learners (it is claimed that the primary learning style in at least 30% of learners is auditory).
