3_is open tools for sharing knowledge

• 3_is is a project on learning and teaching
  devoted to design educational artefacts for
  supporting e-lectures.
• 3_is enables manipulation and sharing of data
  provided during the lectures.

3
3_is key concepts

• gt Dialogical Knowledge Construction (DKC)
• The DKC supports teacher/student, student/teacher
  and student/student interaction facilitating
• processes of exemplifying concepts
• negotiating meaning
• sharing content
• gt Situated Editing (SE) of contents
• The SE enables real time manipulation of
  educational assets.
• Students and teacher can re-organize and produce
  contents in order to create their own version of
  the lecture.

4
DKC and SE design concepts

• The DKC aims to provide equal dignity to
  teacher-student relationship as well as to peer
  to peer relationship.
• The SE to an environment (physical and
  conceptual) where the production of educational
  assets can be co-produced by teachers and
  students.

5
3_is objective

• 3_is aims to design artefacts for enabling the
  construction of dialogical knowledge and the
  capture, organization and manipulation of
  contents provided in the lecture in real time.

6
The concepts

• Regarding the SE each lecture is audio and video
  recorded and matched in a timeline.
• The resources provided during the lecture, as
  documents, slides and web site, are automatically
  captured and associated to the lecture timeline.
• The resource are immediately available on a web
  platform that supports each class in the sharing
  and the manipulation of contents and documents.

7
3_is web platform

• 3_is Web platform (www.saul.unisi.it/3is/)
  includes three main parts
• gt the first module with lecture resources
  developed by Moodle www.moodle.org is a Open
  Source course management system (CMS).
• Moodle over other systems is a strong grounding
  in social constructionist pedagogy.
• gt The second module dedicated to visualize the
  data captured and manipulated during the lecture,
  
• gt the third module allows the dialogical
  interaction through dedicated tools such as
  forum, assignment and quiz.

3_is light software

• During the lectures 3_is light application
  generates automatically in background Learning
  Object (LO).
• 3_is LO is made by the resources presented during
  the lesson by the teacher such as the Power Point
  slide, Web site, text document, pictures and
  audio or video of the lecture.
• At the end of the lecture the LO package can be
  upload in to the on line Course Management System.

9
SCORM Open Standard for Learning Objects

• The Content Structure and Content Aggregation are
  dynamically structured during the lecture

10
3_is light software

• The software creates dynamically a folder with
  the resources presented by the teacher and the
  imsmanifest XML file with the description of the
  resources and the meta-data.

3_is light software

• The Open Standard describes the resources traced
  during the lecture.
• The Open standard allows
• to load and exchange the LO with different
  Learning Management System (LMS)
• to create specific parsing objects.

12
3_is web-based interface

• The LMS moodle with the SCORM module can generate
  automatically the list of the resource.
• Creating a different parsing of the asset XML
  file we can develop more complex web-based
  interfaces.
• For example the 3_is moodle module.

3_is light Conclusion

• Actually 3_is light is developed only for Mac OSX
  in Alpha 0.2 release.
• 3_is light is developed in Apple Script and the
  software is Open Source with GPL.
• Download the software www.saul.unisi.it/3is/

3_is light NEXT STEPFUTURE DEVELOPMENT

• gt To develop a beta version at the end of this
  lecture quarter mid April.
• gt To create an Open Source development group that
  will be composed by software engineers and HCI
  (human computer interaction) experts.
• gt Our idea is to contribute to the Open source
  international community also introducing
  interaction design perspective that could support
  the development of the Open source project aiming
  to create a design methodology.
• Future development will be focused on
• the visualization of the resources in Web site
  and Interactive TV.
• the development of student tool in order to
  monitor her/his activity and to edit the content
  provided during the lecture.
