The Challenges
• The NSF Cyberlearning initiative calls for engineering educators to respond to the compelling need for improved competitiveness in engineering-related fields
• The challenge: to attract – multi-talented individuals – who are interested in the study and practice of
engineering – in socially-aware and collaborative contexts
3
Fun and Games
• The Virtual Engineering Sciences Learning Lab (VESLL) and the Teaching Artificial Intelligence as a Lab Science (TAILS) project – introduce a social element to the learning
experience – incorporate activities that provide the satisfaction
of accomplishment we often associate with game playing
– provide structured labs with exercises that can be completed before students leave the classroom to build a sense of accomplishment and confidence
VESLL
5 5
• Interactive learning environment • Located on an “island” in Second Life• Built around a functional laboratory designed to
introduce students to engineering concepts through visualization and collaborative problem solving
• Assessment activities integrated into the in-world experience
• Imagine: a virtual version of a science museum • e.g., Exploratorium (San Francisco) or Pacific Science
Center (Seattle)• the opportunity to delve into engineering concepts
and maintain a sense of excitement about the experience

Preliminary Workshop Results
• 12 students, Intro to Computer Science (for non-majors)• Characteristics:
– Use email, PowerPoint, Blackboard– but not voice/video chat, teleconferencing,
photosharing sites, immersive platforms; don’t do web page development
• Feedback:– Related to course content– Helped student understand course content– Made course material more interesting

Tell a story about each AI Algorithm
• To be fully literate, students must be able to view software systems at many levels of abstraction
(Rasala, 1997; Crews, 1998; Lethbridge, 2000; Pour, 2000)
• Present algorithms in the context of– software engineering best practices– other computer science coursework – guided exercises that can be completing during class
period– the software “store”
• For CS undergrads and Systems Engineering MS students
20
Components of TAILS Lab Experiments
1.The Idea: Explain what the program segment does without describing how it is implemented.
2.Applications: Real world applications
3.Sample Input/Process/Output: annotated trace of the program in execution (con-ops, black-box testing)
4. Implementation-independent Design Description: functional perspective, top-down manner
21
Components of TAILS Lab Experiments
5. Implementation-specific “HINT” File(s): Partial implementation with HINTs that guide the user in implementing the remainder of the code
6.Test Suite and Driver(s): One driver for each implementation-specific HINT file with relevant data in the test suite
7.Experiments: Implementation-independent set of test data and expected results, plus ideas for enhancements and extensions
22
Components of TAILS Lab Experiments
8.Source Code: The ending of the tale -- solutions to the exercise in the HINT files, more extensive implementations readily available from other sources.
9.Complexity Analysis: Complements the work done in a data structures or algorithms class; reveals the different ways to measure complexity

• VESLL– Augment environment (e.g. activities,
biographies, salary info)– Add adventure-based collaborative problem-
solving– Develop automated docents to guide visitors– Provide a more reactive/reflexive environment
• TAILS– Plans to complete two “modules” for each of the
next 3 years– Merge with VESLL?

Coming back to AI and Fun...
• VESLL and TAILS – Provide socially oriented activities (games requiring
teamwork and collaboration)– Facilitate the transformation between the macro- and
micro-level views of algorithms• Practical issue - platform migration
– Understand problem well enough to design at domain level, then migrate to specific platforms
– Provide a sustainable and sustained development environment
