In this laboratory activity, students were tasked with determining the heat of combustion for each of three common sugar substitutes: saccharin, aspartame, and sucralose. The heats of combustion were determined via three different methods: bomb calorimetry, heats of formation derived from semiempirical calculations, and tabulated average bond…

Students face challenging texts and concepts across the disciplines in higher education, and many students lack the reading skills and strategies to make sense of them. The aim of the small study described in this article was to explore the benefits, if any, of the difficulty paper, a written formative assessment that asks students to explore…
