This demonstration introduces the SIGCSE ComputingThe publication of tested laboratory materials in an on-line Laboratory Repository and will allow the audience to provide journal will be handled within the structure of the Lab feedback that will help tailor the interface. We illustrate two Repository.The prototype for the journal containing peerphases of the project. The current features of the Web-based reviewed lab materials will be presented during the Repository for submitting lab abstracts and searching for demonstration. Audience feedback will be summarized for use specific lab materials are introduced. Reactions of the audience by the Working Group on Designing Laboratory Materials for participants will help refine the Abstract Server.Computing Courses.
