The introduction of block-based coding provided a new method for teachers seeking to teach computer science to beginners. Since then, numerous computing tools utilizing this coding modality have surfaced, each bringing their unique properties to the CS education playing field. But while research comparing blocks to text-based coding have identified benefits and drawbacks of each, the same has not been done solely among block-based coding computing tools. In this poster presentation, we present an experiment seeking to understand which properties of block-based coding teachers find most attractive to their pedagogical needs. Teachers enrolled in a CS pedagogy course completed reviews of 6 block-based coding computing tools, reflecting on whether they would use the tool in their classes. We explain their assignment, guidelines given to scaffold their reviews, and our plan for future analysis.
