This paper presents results from a randomized experimental design replicated over four semesters that compared students' performance in understanding landform evolution processes as measured by the pretest to posttest score growth between two treatment methods: an online interactive simulation tool and a paper-based exercise. While both methods…

Technology provides the means to create useful learning and practice environments for learners. Well-designed cognitive tutor systems, for example, can provide appropriate learning environments that feature cognitive supports (ie, scaffolding) for students to increase their procedural knowledge. The purpose of this study was to conduct a series of…

The purpose of this formative evaluation was to investigate the experiences of preservice teachers utilizing performance support system (PSS) technology to develop knowledge related to classroom technology integration. A PSS provides end users just-in-time support to perform various tasks. Because teachers have time constraints, a PSS can be used…
