Build Your Own Block Programming Language

When students learn basics about programming with Scratch, it can be difficult for them to move to a standard, full-featured language. One approach that can help the transition is to create an expanded blocks language with more of the features of a standard programming language. This poster describes an environment called BloP that enables the development of expanded blocks languages—and (unlike well-known Scratch mods like BYOB and Snap!) allows for hiding setup scripts and locking vital features to create a safer environment for experimentation. You will have the opportunity to experiment with BloP implementations of full-featured languages
