Composition of programming structures into scenarios and their matching with the SOLO levels

This work aims to present the anatomy of a visual programming code, such as Scratch, at different levels. At the command level view point, it focuses on the internal structuring of the commands. For the program structure level, it focuses on the ways that the commands are built from the view points of the sequence, the selection and the iteration program structures. At the program scenarios level, it examines the ways that the program structures are combined and implemented within programming scenarios. At the integrated program level, it focuses on the ways in which the programming scenarios are being assembled within a single program. This work provides a mental scaling of these four categories which can correspond to the upper four levels of the SOLO taxonomy.
