  1. Reasoning in AtgentSchoolFrom conceptual framework to implementationEvents  reasoning  interventionKoen Molenaar – David KingmaOxford, 22-5-2005

  2. Contribution – WP1 • Deliverable 1.1: • Descriptions of Ontdeknet • Cases of usages within Ontdeknet • English version Ontdeknet • Deliverable 1.2: • Intervention model in the learning proces(Regulate, cognitive, meta-cognitive) • Cognitive load theory • Attention & Motivation

  3. Contribution – WP2 • Deliverable 2.1: • WOZ – insights in events • Clarifying relation general and specific components • Deliverable 2.2: • Analysis of events – interventions within Ontdeknet • Relation conceptual framework – Ontdeknet • Deliverable 2.3 • Set up a general intervention model for Ontdeknet • Validation intervention model with WOz • Deliverable 2.4 • Experiences implementing conceptual framework events

  4. Contribution – WP* • WP3 Deliverable 3.1: • Implementation conceptual framework events in Ontdeknet • WP4 Deliverable 4.1: • WOZ – formative evaluation setup. • WP5 • Czech version Ontdeknet • Teacher presentation Ontdeknet • WP6 • Atgentive on national seminars • WP7 • WP3 Kick off – contributions, tasks and planning

  5. What did we do? ….

  6. Why reasoning? • We need to connect the event information to interventions. • Asking questions to the user is: • distracting and disturbs the learning process and • user might not provide reliable information. • Adapt to the amount of available data, which depends on the application / environment. • Allowing the atgentive module to adapt the application to the user.

  7. Been there, done that Lots of theory available on reasoning, using: • Rules • Agents • Decision trees • Neural networks • ….

  8. So what’s the problem? • The Atgentive < >application interface is unclear • All applications are different and thus have different kinds of data available • Do we need planning for automated meta-cognitive support? • Can we parameterize all the needed information?

  9. A few examples • Which external event is important to the user, and when should we notify him? • How to decide on the modality of the interaction? • Limited resources available, how to decide if and what other task to propose? • When to re-attract an idle-user attention (when is a user idle?)

  10. Information available A standalone Atgentive module cannot cope with all the information available from the application. For example: • Cognitive load of the user. • Planning of the user and other resources needed for certain tasks • Actions of the application

  11. Information available (II) • Should the application pre-process the data? • Should the application be able to somehow adjust the reasoning parts in the Atgentive module? • Should the application have the last word?

  12. WOz • The Wizard of Oz construction allows to: • Validate Ontdeknet events (WP4) • Validate C.F. events (WP2) • Validate intervention model (WP4) • Validate the separation between application and the Atgentive module • Validate reasoning rules, before coding them • Collect statistical data? More details about the WOz in the afternoon!
