• The Nature of Arguments Provided by College Geometry Students With Access to Technology While Solving Problems

    Karen F. Hollebrands, AnnaMarie Conner, and Ryan C. Smith
    Prior research on students’ uses of technology in the context of Euclidean geometry has suggested that it can be used to support students’ development of formal justifications and proofs. This study examined the ways in which students used a dynamic geometry tool, NonEuclid, as they constructed arguments about geometric objects and relationships in hyperbolic geometry.
