The Geology Explorer Project
Educational Game designed to provide authentic learn-by-doing experience
•Exploration of a spatially oriented virtual world•Practical, field oriented, expedition planning and
decision making•Scientific problem solving (i.e., a “hands on”
approach to the scientific method
Balancing Pedagogy with
Play
Games have the capacity to engage!
• Powerful mechanisms for instruction
• Illustrate real-world content and structure
• Promote strategic maturity (“learning not the law, but learning to think like a lawyer”)
Technical Approach
• Networked, internet based, client-server simulation
• UNIX-based MOO (Multi-User Dungeon, Object Oriented)
• Java-based clients (text version - telnet based; graphical version in development)
The Game
•Planet Oit - similar to Earth, but opposite the Sun
•Students “land” on Oit to undertake exploration
•Authentic Geoscience goals - e.g., to locate, identify, and report valuable minerals
The Simulation
~50 places: desert, cutbank, cave, etc.
~100 different rocks and minerals
~15 field instruments: rock pick, acid bottle, magnet, etc.
~Software Tutors: agents for equipment, exploration, and deduction
Experiments
Fall 1998 and 1999>400 students in large (>400) non-major Intro class, split into 3 groups
• Planet Oit• Geomagnetic Web-based (alternative)• Control (non-participant)
Rejects the notion of standardized multiple choice tests
Pre-game narrative-based survey• short problem-solving stories • students record their impressions and questions
Similar post-game survey with different but analogous scenarios
Surveys analyzed for improvement in problem-solving
Subjective Assessment

Welcome to the NDSU/CS Geology Explorer MOO
We are implementing Planet Oit for you to explore in order to learn something about geology.
*** Connected ***You are standing in the middle of the expedition staging area
on the surface of Planet Oit. You see a spaceship on the ground with its bay doors open, exposing a laboratory within. A glorious panorama spreads out on all sides.
There is a Way Station here* To the North is a Seashore* To the Northeast are the Hills* To the East are the Old Mountains* To the Southeast is a Laboratory* To the South is a Desert* To the Southwest are the Plains* To the West are the Young Mountains* To the Northwest is a LakeObvious exits are: Down Station North Northeast East
Southeast South Southwest West Northwest
A TranscriptAs a player in the Geology Explorer You have reached no goals yet, and you are playing at the beginner
level. You have a general goal: to 'report' all the rocks and minerals you
find and a specific goal: to 'report' the location of Native Copper. Native Copper is a reddish metallic mineral. Native Copper is used in electronics. You can expect to find Native Copper in Desert (#147) In particular, you should look in Plateau with Fissure (#350).To see this message again, type '@showgoal' or 'showgoal'
=> SOUTHEASTLaboratoryYou are standing in the laboratory of a spaceship, you are surrounded by
many instruments.A sign on the wall says, 'You can buy field instruments to the East.' The sign continues: 'You can use these lab instruments by bringing samples back
here.'* To the East is a Shopping Center* To the South is a Rock Museum* To the Northwest is Planet-OitObvious exits are: East South Northwest
=> EASTCrazy Eddie's Geology Equipment EmporiumCrazy Eddie's is the place to go to fill all your geology field equipment needs. Aisle
after aisle of merchandise makes this place into a maze.You could easily get lost in here without assistance.
A large sign on the far wall reads:
Trouble finding what you're looking for? Look it up in our catalog!
(Never mind the cost -- everything is free)
Obvious exits are: WestYou see Crazy Eddie and Catalog here.Crazy Eddie says, "Hello, demoplayer. Welcome to Crazy Eddie's Geology Equipment Emporium!Crazy Eddie says, "I've got the best deals on Planet Oit!"Crazy Eddie asks, "Can I get you anything?"

=>WESTCinder ConeYou are standing at the base of conical hill formed by the accumulation
of cinders around a volcanic vent. The landscape here is brown and black, there is very little in terms of green growing things. The air smells faintly of sulfur.
* To the East is a Plateau with Fissure* To the Southeast is a Desert* To the South is a Reddish Butte* To the Southwest is a Cave
Obvious exits are: East Southeast South SouthwestYou see dull reddish porous medium-grained outcrop (#1923), dark gray fine-grained outcrop (#2082), black smooth glassy block (#2087), and
grayish white rough glassy porous block (#2100) here.
<the player is visited by the tutor>
A clap of thunder splits the air, and a tutor appears in your midst The tutor appears to be speaking to demoplayerTUTOR: You just left Plateau with Fissure containing your goal: Native
CopperThe TUTOR bends at the waist and disappears in a puff of smoke
<the player returns to the Plateau with Fissure>
Deductive Tutors
1. Equipment tutor
2. Exploration tutor
3. Science tutor
Detects when a student makes a wrong guess and why (i.e. what evidence they are lacking); or when a student makes a correct guess with insufficient evidence (i.e. a lucky guess)
