Lessons in Combining Block-Based and Textual Programming


Tiled Grace is a block-based programming system backed by a conventional textual language that allows switching back and forth between block-based and textual editing of the same code at any time. We discuss the design choices of Tiled Grace in light of existing research and a user experiment conducted with it. We also examine the sorts of task preferred in each mode by users who had the choice of editing either as blocks or as text, and find both positive and cautionary notes for block-based programming in the results.
