Evaluation of an Intelligent Tutoring System used for Teaching RAD in a Database Environment

This paper presents an evaluation of the Personal Access Tutor (PAT), an Intelligent Tutoring System (ITS) for Learning Rapid Application Development (RAD) in a database environment. We first give an overview of Microsoft Access, the environment that PAT uses. After describing related work in the field, we discuss the architecture of PAT and the services that PAT offers to the students, together with a short introduction of how students use PAT. After presenting the evaluation methodology, the results of a summative evaluation are discussed. Additional evaluation using data gathered from students by PAT is analysed as a pre-post test. The paper concludes with a summary and describes further work.
