AtGentive IST-4-027529-STP - Attentive Agents for Collaborative LearnersFigure 9 - Example of an AtGentNet "portlet"2.2.5 The animated AgentThe formative evaluation phase of AtGentive showed that an animated agent in the formof a young woman (see Figure 1) would be the most acceptable character for AtGentNet.This character was named “AtGentiGirl”, after “Elastigirl” of popular culture (a“superhero” who appears in DC Comics 1 and the feature file “The Incredibles” 2 ). Thisname was chose due to the character’s similarity of appearance to this fictional characterand the AtGentNet user demographics (a median age group of = 26-35) fitting with thetarget audience for “Elastigirl”.For AtGentNet, the animated agent only appears as a result of an explicit user requestfor help (and only for the experimental group). As described above, the agent is used todeliver Scenario N1 – (Initial) learning guidance. The embodied agent “walks” around thescreen, pointing at relevant items and giving an explanation.2.2.6 Continual developmentAtGentNet underwent refinements at the pre-pilot stage. These changes were basedupon further analysis of the system by INSEAD, AtGentive partners’ feedback andunderstandings gained from the formative evaluations. However, once the pilot studybegan only essential changes were made to the software.2.2.7 User Evaluation PilotAll students on the 2007 ITM training course took part in the user pilot, which ran for thewhole of the training course (May to October 2007). One country was excluded from thestudy (and used a separate version of the ICDT platform) as it was felt that the internetinfrastructure in that country was not sufficiently mature to support the pilot. This gave 27participants for the pilot.1 Elasti-Girl: http://en.wikipedia.org/wiki/Elasti-Girl2 The Incredibles, the movie : http://www.pixar.com/featurefilms/incredibles/chars_pop2.htmlDel 4.4: AtGentive Final Evaluation Report page 18
AtGentive IST-4-027529-STP - Attentive Agents for Collaborative LearnersAll students from any one country were allocated the same group (Control orExperimental). This ensured that students most likely to discuss the platform in the initialstages were seeing the same interface. Countries were allocated randomly into groups.13 students were in the Experimental group (using the new AtGentNet version of theICDT platform) and 14 students were in the Control group (using the same version of theplatform, but with the advanced features disabled or not visible). Participants were notexplicitly made aware of the difference in the two systems, and each participant couldsee and interact with all other participants, regardless of group.The user pilot took place in two stages:• General use – all participants, 24th May to 4th September 2007• Simulation Exercise – self-selected participants, 5th September to 10th October2007The second stage comprised a business simulation exercise. Participants were sent anemail asking them to take part in the simulation by watching an online video presentationdescribing a business situation in which the fictional Eagle Racing company attempts tofind sponsors for their motor racing team. After the first video participants were asked todiscuss the dilemma and vote secretly on their choice of action (one of two available).Participants were then allocated into one of two groups, according to their decision. Forthe next three weeks each group then discussed future dilemmas using a separateprivate discussion area on the platform.AtGentNet was developed using the Extreme Programming methodology (Beck, 1999).This requires an iterative process of develop-test cycles. However, it is crucial to bear inmind the limited time available for AtGentNet users to use and report on the system. Thebusiness professionals involved (see Section 3.1.3) were not able to make multiple testsof the system. Therefore, the partners and user representatives at STC offered feedbackon AtGentNet during the development stage. The platform then remained effectivelystable during the user pilot.2.2.8 Timetable of eventsBelow is shown the timings for evaluation activities related to AtGentNet.MayUser evaluation pilot began with an introduction to AtGentNet for TRIM participants atmeeting in Lidköping, Sweden on 24th May 2007September 2007“Eagle Racing” simulation began on 5th September 2007 with interested (self-selected)TRIM participantsInitial questionnaire – users’ background and use of and attitudes towards the ICDTplatform and the animated agent – sent out 20th September 2007October 2007“Eagle Racing” simulation completed on 10th October 2007.Del 4.4: AtGentive Final Evaluation Report page 19
