GRAPPLE Authoring Tool (GAT)
• Separates the challenge of creating an Adaptive Course into four distinct areas:– Domains (e.g., Astronomy, Finance, etc.)– Pedagogical Relations (prerequisites, etc.)– Learner Models (beginner, int, adv learners; etc.)– Courses (combine above elements)
• GAT provides tools to address each area– Different authors use different tools!– Separate editing views for beginner/ advanced
authors
THE DOMAIN TOOLDefining Concepts
Domain
• Structure content into concepts• Relationships defined between concepts
is-composed-of
is-a
Domain: Concepts
• Concepts– Name and Description– Resources: URLs to actual content– Properties: Metadata• These can be used for pedagogical purposes
later on in the course tool– E.g., the order of the concepts in the menu
Domain: Relationships
• Relationships– Allow the definition of inherent domain
links between concepts– Custom relationships can also be defined– These can be used for pedagogical
purposes later on in the course tool• e.g. “parent” relationship allows the menu to
be structured
Jupiter Planetparent
Domain: Concepts
THE COURSE TOOLCreating a Course
Creating a Course
• Author can create a course by using pedagogical rules and domain concepts
• A beginner author has a list of pedagogical rules to select from
Basic Pedagogical Rules
• Rules define the behaviour of the course• For instance G(rapple)-Prerequisite:
States that Planet should be visited before Mars is recommended
Items: Planet
Name: source
Items: Mars
Name: targetG-
Prerequisite
Basic Pedagogical Rules
• G(rapple)-Start
• G(rapple)-Layout
Items: Solar System
Name: selfG-Start
Items: Solar System, Planet, Star
Name: selfG-Layout
States that Solar System should be
shown first
States that Solar System, Planet and
Star should be included in the layout menu for
the course
Basic Pedagogical Rules
• There are 12 default pedagogical rules– G-Prerequisite-Parent– G-Knowledge-Update– G-Knowledge-Propagation– G-Knowledge-Propagation-Parent– G-Hide– G-Unhide– G-Visit– G-Quiz
Creating a Course
• Insert pedagogical rules into the course
• Insert concepts into the sockets of the rules

CREATING PEDAGOGICAL RULES
Advanced Mode: Defining pedagogies
Creating Pedagogical Rules• Advanced users can use the Pedagogical
Relationship Type tool to define their own rules:
Creating Pedagogical Rules
• In the Meta Info tab, authors can add a comment to describe how the rule behaves
• Parameterscan also be defined
Creating Pedagogical Rules
• Adaptation rules can be specified using GALE code
%target% {#suitability & !`(${%source%#knowledge}>%level%)`}
Creating Pedagogical Rules• Rules can read/write learner model variables
Creating Pedagogical Rules• Constraints can be specified:
Creating Pedagogical Rules• Associating domain relations with this rule
DEMO
Conclusions
• GAT divides the authoring challenge into:– Domain– Course– Pedagogical Rules
• Authors can specialize according to their ability and interests
• Tools use simple paradigms, with graphical representations
Conclusions
• Come to the Authoring Workshop this afternoon to get a hands-on experience!
• Thank you for listening
