VILLE: a language-independent program visualization tool
Teemu Rajala, Mikko‐Jussi Laakso, Erkki Kaila, Tapio Salakoski · 2007
Visualization tools have proven to be useful for enhancing novice programmers' learning. However, existing tools are typically tied to particular programming languages, and tend to focus on low-level aspects of programming such as the changing values of variables during program code execution. In this paper we present a new program visualization tool, which provides a language-independent view of learning programming. Moreover, program execution can be viewed in two languages simultaneously. Complete with role information of variables, the tool supports the learning process at a more abstract level, thus emphasizing the similarities of basic programming concepts and syntax in all imperative programming languages.
