3D virtual worlds:
Simulation of immersive environment Users are represented by avatars Interaction among users Interaction with objects
Virtual worlds lacks of some learning elements:
Learning objects Instructional design Intended learning outcomes Management of roles Assessment

3D ASSESSMENT(I)
6
New mechanisms for assessment are necessary
Virtual worlds allow the assessment of knowledge and competences
The user’s attention must be maintained (flow) Embedded assessment
3D ASSESSMENT (II)
7
Different virtual worlds have been used to asses students:
River City Quest Atlantis Second Life quizHUD

ACTIONS: PROMPT
9
It can be showed in different ways:
A text message Talk with a NPC (AIML) An audio message
Students can do several actions to get the instructions: Approach to a NPC Select a NPC Select an object Access to a zone
ACTIONS: ANSWER
10
Students can do several actions:
Select an element in the virtual world NPC Object Zone
Talk with a NPC (AIML language)
The different options among student have to choose can :
Be visible all the time Appear when students get the instructions Disappear when students give their answer
ACTIONS: FEEDBACK
11
Different types of feedback:
Question’s feedback A text message Insert an image An object can appear An object can disappear Play an audio file
Test’s feedback Students receive their feedback and their final score
HELP SYSTEM
12
The time between the answer of a question and the beginning of the next one must be reduced
A track can be added to every question It is used to guide students toward the next question
Students use the menu bar to access to the track

Questions are loaded from external files
The files are defined following the IMS QTI specification
This engine implements questions of the “multiple-choice” type
This engine is formed by:
NewAPIS Open Wonderland
FEATURES
14
QTI engine v2.1
Management of test Management of questions
It loads the QTI XML files
It manages the students’ answer
It stores all the assessment data, checks the answer of the students and calculates their scores
NEWAPIS
15
Open Source
It is written entirely in Java
It is a distributed client-server architecture
A WebDav-based content repository is hosted in the server
Its functionality is divided in different modules
OPEN WONDERLAND (I)
16
OPEN WONDERLAND (II)
17
Main features:
It supports desktop application sharing Integration with external data sources It has spatial sound capabilities It allows the communication among students
Chat Audio
Different users can see different objects
Virtual worlds introduce new interactions that there are not considered in QTI
This engine use two files:
QTI XML file It is managed by newAPIS
WL-QTI XML file It is managed by Wonderland It relates every part of a question with the corresponding
object in the virtual world It includes additional information

21
Virtual worlds allow the assessment of students in a richer way
The use of the IMS QTI specification allows:
Reuse of existing assessment content Use an existing QTI engine that can manage the
actions that are not directly related with the virtual world
CONCLUSION
22
Include new types of questions It allows the management of new interactions in the virtual world
Improve the management of test
Create an authoring tool to create the WL-QTI files
Add different capabilities for objects in the virtual world by processing the WL-QTI file
Use this assessment engine in a real education context
