Course Title: Introduction to Statistical Reasoning
Carnegie Mellon University redesigned Introduction to Statistical Reasoning, which enrolls 400 to 500 students per year, over a third of the freshman class. This was a "second generation" redesign of a traditional lecture-plus-recitation statistics course. Stage one created a lecture-plus-computer-lab design that gave students experience with designing and implementing analyses of statistical data using a statistical software package. Stage two introduced an automated, intelligent tutoring system called StatTutor to monitor students' work as they go through lab exercises, provide them feedback when they pursue an unproductive path, and closely track and assess individual student's acquisition of skills in statistical inference—in effect, providing an individual tutor for each student. The goal was to make labs and homework more open-ended, exploratory, and active and to change the staffing model to make the course less labor intensive. CMU's 1991 redesign reduced costs from $227 to $195 per student. The redesign plan that added StatTutor expected to further reduce costs from $195 to $138 per student or an additional 29% savings, resulting in an anticipated total savings from the two redesigns of 39%. The results of the completed redesign can be found by following the links listed below under Final Report.
