Introduction
This page is a about the integration of the electronic chalkboard software
eChalk and the intelligent learning environment
ActiveMath.
Motivation / Requirements
Several factors motivate the integration of ActiveMath features into eChalk. We categorize them according to the point of view of the stakeholders involved in usage scenarios. The scenario set currently consists of to the following main use cases:
- The lecturer uses eChalk in front of the students
- Students use the eChalk recording to post-process the lecture
- Students use ActiveMath to post-process the lecture
Lecturer Perspective
Here's a short list of integrations the lecturer would probably benefit from:
Before the lecture
- Support for authoring ActiveMath LO's for chalkboard import
- Structuring authored LO's
During the lecture
- Import of ActiveMath LO's into the chalkboard
- Usage of tools building on AM capabilities to explore new presentation possibilities - e.g., a domain viewer representing the dependencies between learning object in a graphical way.
- On-the-fly authoring of ActiveMath LO's based on a clustering of the chalkboard drawing, followed by some kind of OCR
- Dynamic insertion of supportive learning objects (examples)
- (Semi-)Automatic annotation of eChalk output (pdf?)
- Support for polls (Who has fully understood X)? (anonymous!)
After the lecture
- Structuring LO's used during the lecture as AM book
Student Perspective
Before the lecture
- Sneak preview of the lecture (collection of LO's prepared for the lecture + graphical 'roadmap')
During lecture
- polls - anonymized comm channel to the lecturer?
- annotation of LO's
- LO import is less error-prone than chalk writing
- Chalkboard drawing quality is improved
After the lecture
- Supportive content+exercises available
- Rich feature set of AM can be used (CAS-supported exercises, Course generator...)
- Transcript of chalkboard (pdf+video) annotated with links to AM and vice versa
