DesignFirst-ITS is an intelligent tutoring system that provides one-on-one tutoring to help beginners with various learning styles learn object-oriented analysis and design-frist approach in a CS1 course. DesignFirst-ITS will interact with students through two systems. One way is through an integrated development environment (IDE) in which students design and code their project solutions. Here, DesignFirst-ITS will observe the student's progress and offer assistance based on pedagogical strategies adapted to the individual. Another way is through multimedia courseware called CIMEL (Collaborative, constructive, Inquiry-based Multimedia E-Learning). CIMEL covers a breadth of topics in computer science, including introductory concepts in Java and object-oriented programming. The ITS can refer students to portions of CIMEL for review of topics needing reinforcement, and determine the student's level of understanding from the student's performance on quizzes and interactive exercises within CIMEL.
