Educational Role-playing Games “Learning-by-doing” Experiences
MultiUser Exploration Spatially-oriented virtual worlds Practical planning and decision making
4
Educational Role-playing Games “Learning-by-doing” Experiences
Problem solving Scientific method Real-world content Mature thinking
5
Advantages of Virtual Worlds
Collapse virtual time and distance Allow physical or practical impossibilities Participate from anywhere Interact with other users, virtual artifacts, and software agents Multi-user collaborations and competitive play
6
Technical Approaches Networked, internet-based, client-server
MultiPlayer Simulation-based Implemented in Java applets
7
Technical Approaches MUD = Multi User Domain
MOO = Object Oriented MUD Multi-user database for implementing objects and methods to represent rooms, containers and agents
8
Technical Approaches MUDs and MOOs are typically task-oriented with keyboard interactions Ours are also graphically-oriented, point & click interfaces

10
The Virtual Cell User Interface
11
The Virtual Cell Rendered in VRML (Virtual Reality Modeling Language)
12
You are a biologist who can “fly around” inside the cell.
13
Users are assigned specific goals For example: Identify 5 different organelles
14
A Virtual Laboratory is attached
15
The Cell User movements are tracked by MOO software.
16
Users set up experiments in the Cell to accomplish their assigned goals.

The Virtual Cell: Assessment Protocol Text-Based Virtual Cell
Pre-course Assessment: 400+ students Computer Literacy Assessment: Divide by Computer Literacy and Biology Lab Experience Text-Based Control Group: (150 students, approx.) Virtual Cell Treatment Group: (125 students) Web-Based Alternative Group: (125 students) Post-course Assessment: 400 students

Mean Post-Intervention Scenario Scores
Module: Group No. Organelle ID Cellular Resp. Text a 10.6a Web b 13.7b VCell c 17.3c Within any column, any two means followed by the same letter are not significantly different at P=0.05 using the LSD mean separation test.
21
What we have found: Virtual Cell is currently a supplement to Introductory Biology lectures. It has the potential to replace certain sections of a course. It can also be used in laboratory settings. Virtual Cell does provide an authentic experience.
