AgentSheets in India When the Jiva-Java Project started, its 20 secondary students had never used a mouse or seen the Web. Three weeks later, they had created applets (using Agentsheets authorware) and linked them to their own Web pages –Ed Gaible at the Jiva Institute Faridabad, Haryana, India

Out of this World (very distance education) NASA used AgentSheets to simulate an “E.coli in microgravity” experiment aboard the space shuttle Discovery with John Glenn

Objectives  Develop sense of what objects are and how they interact with each other  Hands on experience of designing and implementing highly interactive systems (games).  Apply principles of Object Oriented Design  Learn to use UML to represent and communicate OO designs  Learn to work in group: presentation and communication skills  Evolve designs by presenting to larger group  Critique other people’s design  React to other people’s critique

Approach  Build games  WHY? Games… u contain complex interactions between objects and users

Structure of course  1) Quick Introduction to OOD u What is an object/class/instance/method …? u UML basics u Prototyping  2) Individual Weekly Game projects u Build simple game, turn in game and UML- based description  3) Group Projects u Work in groups of 3-5 u Present progress weekly

What this course is not  No handholding about programming  Not very theoretical: the only way to learn about OOD is to build systems and to discuss them with others
