Effective Practice Abstract/Summary
Abstract/Summary of Effective Practice: 

Pennsylvania State University designs a hybrid statistics course, which combines lectures with computer-mediated workshops, to address learners' needs and lower costs.

Description of the Effective Practice
Description of the Effective Practice: 

An Introductory Statistics course at Penn State University (PSU) currently serves more than 2,800 undergraduate students. The Statistics Department found that the traditional course delivery model did not serve the student needs and was not cost-effective. The redesigned model addresses both pedagogical concerns as well as cost issues. The restructuring involves a reduction from three to one in weekly lectures -- to give faculty more time to interact with students and less time to prepare and deliver the lectures. Two of the traditional lectures have been replaced with computer-mediated workshops. Faculty and teaching assistants utilize these workshops to provide interactive and substantive feedback to students. In addition, the redesigned course offers a variety of online learning materials as well as computerized testing. With the new testing model, students have more practice time and feedback. The redesigned course provides a more interactive model of student learning and reduces costs, particularly in terms of TA support typically required in large, traditional lecture sections.

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.
