May 2007AtGentive IST-4-027529-STP - Attentive Agents for Collaborative LearnersFinal training for teachers using Czech version of AtGentSchool in Prague on 2nd May2007User evaluation pilot began in five schools in and around Prague on 3rd May 2007June 2007User evaluation pilot ended on 14th June 2007Teachers and Expert focus group in Prague on 27th June 2007. Details of the workshopare given in “5.4 – Report from the Workshop arranged to Analyse the Results of thePilot”August 2007OBU and UTA completed a detailed heuristic evaluation of AtGentSchool, which wasdistributed within AtGentive on 6th August 2007. It was necessary to delay the start ofthis heuristic evaluation until an English version became available.2.2 AtGentNetScenarios for AtGentNet were created as a result of the formative evaluation (seedeliverables D4.2 and D4.3). In particular, they take into account the partners’ use of theICDT platform, discussions with a representative of the users (Hasse Karlsson fromSTC) and direct user feedback in the form of questionnaire study. This study is reportedhere, followed by the three scenarios.2.2.1 Scenario N1 – (Initial) learning guidanceThis scenario is intended to support self-directed learning. A new user is guided throughthe platform by being given tasks to work on, ensuring they have completed the taskscorrectly. The guidance is in three steps: (1) create a user profile, (2) learn about thefeatures of the platform and (3) learn how to supply information and communicate withother users. This process may take place over several logins to the platform (the systemwill remember where the user was).Note that this is an exception to the usual user experience of the ICDT platform (and thusAtGentNet) where the user has free reign over his or her work and creates / selects hisor her own tasks. It also contrasts with AtGentSchool where the user experience is oneof being guided throughout by an embodied agent.Note also that this is similar to the new-user introduction in Ontdeknet (and thereforeAtGentSchool). However, the Ontdeknet system already contains this new-userguidance, so the guidance will appear both in the control and modified versions. WithAtGentNet, the new-user guidance is implemented as a scenario, and will only appear inthe modified version, allowing evaluation of its usefulness.2.2.2 Scenario N2 – Notify tutor of user (in)activityThis scenario allows the tutor to encourage students who have not read importantdocuments or messages.When the tutor logs in, if (s)he has posted documents which (s)he has requested thatstudents read or respond to, (s)he will be notified of individual students that have notread / responded.Del <strong>4.4</strong>: AtGentive Final Evaluation Report page 16
AtGentive IST-4-027529-STP - Attentive Agents for Collaborative Learners2.2.3 Scenario N3 – Notification of eventsThe purpose of this scenario is to assist students to identify the most useful, relevant andurgent documents to attend to.When the students logs in, (s)he is notified about documents based on their socialnetwork,interests, etc. The notification criteria are controlled by the tutor.2.2.4 ImplementationUnlike AtGentSchool, the agent is used only to deliver specific help information.Implementation of the scenarios in AtGentNet is based upon support for the learner’sperception, via entries in a number of additional “portlets” – small window-style displayareas within the main display area – that may be repositioned by the user (see Figure 9).In addition, AtGentNet incorporates changes in the software to enhance perception, asthis is an attention-related factor identified by the Conceptual Framework. The additionalportlets made available to AtGentNet users are:• “Watch” portlet – allows the user to select specific postings for which changes /access details are displayed in the Watch portlet on the Home page• The Watch tab – calls up an expansion of the Watch portlet, listing a greaternumber of watched items and allowing statistical details to be displayed via the“analyser agent”. Scenario N2 – Notify tutor of user (in)activity – is implementedhere, in that the user (in this case a tutor) may select a posting to watch and thenobtain a list of users who have read that posting• “Agent On / Off” portlet – allows the user to request a number of general“interventions”, such as help in using the platform. These are delivered by theembodied agent. Scenario N1 – (Initial) learning guidance – is implementedhere, in that the user may request the agent to “walk around” the platform anddescribe the most important elements, their use and usefulness.• “Agent”, Pending interventions portlet – the main initial communication pointbetween agent (not embodied agent) and user, detailing “interventions” (i.e.suggestions, such as specific postings the user may benefit from reading). Thisportlet is shown on the Home page. Scenario N3 – Notification of events – isimplemented here, in that the user is shown a list of the most important postingsfor them to read• The Agent tab – calls up an expansion of the Agent portlet, listing a greaternumber of “interventions” and allowing details to be displayed of a selectedintervention• “Knowledge” portlet – lists the recent most popular postings• The “Knowledge” tab – calls up an expansion of the Knowledge portlet, listing agreater number of popular items, along with statistical details of popularity overthe last seven and 30 days• “Community” portlet – lists details of recent visitors to the platform• The “Community” tab – calls up an expansion of the Community portlet, showingmore lists, such as “Most prolific authors”, along with statistical details of platformuse over the last seven and 30 daysDel <strong>4.4</strong>: AtGentive Final Evaluation Report page 17
