Classification of the programming styles in scratch using the SOLO taxonomy

The present study attempts to categorize the programming styles of sequential, parallel, and event-driven programming using as criterion, the level of adoption of the structured programming design techniques. These techniques are modularity, hierarchical design, shared code, and parametrization. Applying these techniques to the Scratch programming environment results in a two-dimensional table of representative code. In this table, one dimension is the types of the aforementioned programming styles and the other is the characteristics of structured programming. The calibration of each of the dimensions has been held with the help of the levels of the SOLO taxonomy. This table can develop criteria for evaluating the quality characteristics of codes produced by students in a broader grading system.
