At Texas State University, and in partnership with the educational technology company Trinket, we have developed a block-based, drag-and-drop editor to control GlowScript VPython output, as an alternative to the already existing text-based GlowScript functionality at Trinket. Students in two different courses have now used this tool, called "GlowScript Blocks", for two semesters. I will present the motivation for the project, the rationale for the design, and some sample instructional tasks. I will also present a variety of data that we have collected to try to assess the impact on student learning of computation: student perceptions of the GlowScript Blocks tool and the associated lessons, performance on a standardized computational thinking assessment, student products from a design project, and performance on some targeted research tasks involving GlowScript Blocks. The results so far are mixed, with many remaining opportunities for improvement of students' affect and learning.
