MUPPETS: Multi-User Programming Pedagogy for Enhancing Traditional Study: An Environment for both Upper and Lower Division Students

Abstract

This paper discusses the pedagogy and use of MUPPETS (Multi-User Programming Pedagogy for Enhancing Traditional Study) for both introductory and advanced students. MUPPETS is a desktop collaborative virtual environment (CVE) that allows students to learn introductory programming skills through the creation of objects and avatars. The goals of the MUPPETS system are twofold. First, the MUPPETS system provides a complex, interactive, collaborative playground in which introductory students can learn the fundamental principles of objects-first programming, which places emphasis upon encapsulation, inheritance, and polymorphism over traditional constructs such as selection and repetition. Objects created by introductory students can be shared with peers and upper division students. Second, the MUPPETS system provides a mechanism through which upper division students can contribute to the success of introductory students. Upper division students are responsible for the development of MUPPETS extensions as well as complex artifacts intended for use within introductory courses
