This paper describes the development of interactive multimedia modules which provide supplementary tutorials on basic topics covered in introductory computer science classes. Two such modules were implemented on the topics of number conversions and basic operating system information. The first versions of the tutorials were evaluated in a study using protocol collection and a post-test with a number of student participants. Results from this study led to the re-design of several portions of the tutorials, which now have a greater level of interaction and progressive assistance for problem-solving.
