  1. Improving Statistics Instruction My Experiences Using Various Delivery Methods Raj Sampath DeVryUniversity November 18, 2013

  2. Devry University • Founded 1931 by Herman DeVry. • Was originally a technical institute. • Earned University status in 2002. • Offering degrees in: Electronics, Business, IT. • Year round eight week sessions: Jan/Feb, Mar/Apr, etc. • Proprietary data restrictions.

  3. The Course • Introductory statistics course for undergraduate business majors. • Course covers: Descriptive Statistics, Probability, HT and CI, and Regression. • The same curriculum taught for more than ten years in all delivery formats using same text. • So unique perspective to analyze effectiveness of various delivery methods.

  4. Onsite • More breadth and depth to course. • More time for reinforcement activities. • Separate lab class. • Pass rate information not available, but closer to blended then online. • Ideal delivery method but may not be suited to online/hybrid course growing popularity.

  5. Online • Online has lowest pass rate. • Emphasis on calculations through virtual white board or videos. • Lecture/Video on each week topic needed. • All concepts need to be reinforced on discussion board. • Calculation questions to try on discussion board.

  6. Blended (Hybrid) • Able to harness the best of onsite and online. • Topics can be “flipped” on line in between classes and wrapped up next class. • Online discussion board can be used to “catch up” if falling behind on course material. • Pass rates higher than online.

  7. Flipped • Flipped topics: introduction to sampling techniques, and data collection methods. • Flipped topics: online discussion board more successful than classroom. • Students confused when other students explain new topics if not given enough prep. time. • Also flipped class through quick intro to topic and then case study in groups.

  8. Pass Rates (Current Averages) • Last 3 Sessions Taught in 2013 • Online: 86.6% • Last 3 Sessions Taught for Business Students in 2011 • Blended: 96.9% • Onsite unavailable: • Attempting to acquire and disseminate future class data.

  9. Future Plans • Flip entire class by effective learning tools such as: case studies, and group projects. • Develop larger case study “bank” between colleges. • Develop online course with 2 “Face to Face” (F2F) meetings. • Continually promote Academic Integrity, Rigor, and Reputation.
