STEM and Educational Robotics Using Scratch

Educational robotics applied to STEM (Science, Technology, Engineering, and Mathematics) activities combined with a project-based learning (PBL) methodology provides quite good results. Throughout this work it is described how to make use of Scratch, a visual programming environment, as a cost-effective tool with great potential for students to work on concepts related to robotics. When students work with Scratch, they can develop animations or video games in which real life applications are simulated. In this paper you can find the description of the intermediate Scratch module. This module is part of an introductory robotics course consisting of the use of three tools (Scratch, Crumble and Arduino) and three difficulty levels (basic, intermediate and advanced). In addition, the results obtained for the Intermediate Scratch module and a discussion of the most important aspects related to the findings obtained are also provided.
