Block-oriented programming with tangibles: An engaging way to learn computational thinking skills

Block-oriented programming environments, such as Scratch and AppInventor, have become mainstream and have helped introduce non-programmers to algorithmic thinking; that is, to computational thinking (CT) skills. In various experiments, referenced in this paper, we observed how objects (tangibles) augmented with digital properties-that is, tangible user interface (TUI) objects-can help develop CT skills. We investigate which paradigm can be used to introduce CT skills with TUIs. By drawing on past experience, we conclude that block-oriented programming provides a suitable answer to our research questions. Furthermore, we introduce a framework for implementing block-oriented programmable objects that we believe can help end-users learn CT skills
