Randy Hengst is a long time educator. He began his career in 1975 as a 6th grade science teacher and subsequently taught 4th grade. He has also worked as a building-level administrator in middle and elementary schools. He was a middle school assistant principal when the first Apple II lab was placed in the school building. As an elementary principal, he helped a handful of 6th grade students learn to use HyperCard. He earned a PhD in 1990 and has worked as a teacher since 1993 at Augustana College, Rock Island, IL. There, he introduced the teacher candidates to scripting within HyperCard and HyperStudio. His current projects are all developed with LiveCode for iOS and are designed to support a collaborative program with a local elementary school, the Number Sense Project. In this project, elementary education majors work with college faculty and kindergarten teachers to design and implement lessons designed to facilitate the kindergarteners' sense of numbers. The elementary education majors and kindergarten teachers regularly make suggestions to create new and modify existing apps.
