Evidence of Effectiveness:
Since many of the instructional tasks associated with the traditional Elementary Statistics course have been replaced with the interactive computer-mediated model, there is a direct reduction in the costs for faculty and teaching assistants. PSU estimates an overall 30% reduction in cost-per-student -- from approximately $176 to $123. Annually, this means a projected savings of more than $115,000. This redesigned course is a mixed delivery model (combination of face-to-face and online) that not only addresses cost-effectiveness and the wise use of resources, but learning goals as well. That is, the department specifically wanted the new course to be such that students would be able to: understand and apply basic concepts of statistics (e.g., variables, inferences, probability); actively participate in data analysis and design; critically evaluate reports containing statistical analyses of surveys and experiments; and, actively engage with course materials and other students. (taken from Pew Web site) Estimated costs associated with this practice: The redesigned course model anticipates an overall cost reduction of 30% or $115,000+ annually. This would be a likely reduction from the traditional course model of $176 per student to $123 per student for this mixed delivery model. Relation to other pillars: Learning effectiveness and student satisfaction: The primary rationale for the restructuring was to address academic concerns, such as poor student performance. In a traditional lecture and recitation format, differing student learning styles were not acknowledged. The interactive approach of the mixed delivery model improves the curriculum by focusing squarely on learner needs.
