Assessment of data carriers with the SOLO taxonomy in Scratch

The assessment of data in Scratch using the SOLO taxonomy is part of a broader framework for setting standards for the assessment of STEM educational projects in the Panhellenic Educational Robotics Competition of WRO-Hellas. The relevant factors of the data that are developed and studied are the forms, the types, the ways of use, the carriers, the visibility, the organization, the processing and the naming. In this work we examine the data carriers which are the “objects” with the code, the costumes and the sounds as well as the backgrounds of the stage. The data carriers are assessed through a categorization using the SOLO taxonomy. This categorization can be used by the educator as a tool with measurable criteria either to evaluate the learning outcomes that the influence of the data carriers has in the students’ code or to develop personal teaching paths, thus creating mental scaffolds that may help students to acquire new knowledge.
