We may not have to reinvent
the wheel, but we can make
 it better, adapt it to today’s
 times, and tweak it to meet
  the needs of our students.
It’s all about student learning!
 “Learning results from what the student does
 and thinks and only from what the student
 does and thinks. The teacher can advance
 learning only by influencing what the student
 does to learn.”
                             —Herbert Simon
                OLI Goals
• Develop exemplars of scientifically based
  online courses and course materials that
  enact instruction and support instructors

• Provide open access to these courses and

• Develop a community of use that contributes
  to the evaluation, iterative improvement, and
  ongoing growth of the courses and materials.

   Data Analysis Problem:
 Oh, okay. Um, I'm not really sure if- do I need to uh we can
 just, like, graph it, right? Uh line plot, I guess. … oh, uh
 histograms, bar charts maybe a boxplot? Uh, no... Uh, uh
 histogram, um data table, um…in statistics class that always
 worked when you got stuck, just make a boxplot, and see
 what happened. So uh, I'll boxplot them, um, y by x. [bleep]
 Uh oh, it says the variable rank has 30 categories, shall I
 continue? Usually that was bad, so I cancel that, because it
 shouldn't come out like that…
The OLI Statistics Course
    What is a Cognitive Tutor?
• A computerized learning environment
  whose design is based on cognitive
  principles and whose interaction with
  students is based on that of a (human)
  tutor—i.e., making comments when the
  student errs, answering questions about
  what to do next, and maintaining a low
  profile when the student is performing well.
Feedback Loops
Summary of ―Accelerated Learning‖
• The OLI students completed course in 8 weeks with 2
  class mtgs/week. Traditional students completed the
  course in 15 weeks with 4 class mtgs/week.

• OLI & traditional students spent the same amount of time
  in a given week on Statistics outside of class

• The OLI students gained much more (on the CAOS test)
  than did the ―traditional controls‖

• There was no significant difference in retention between
  OLI students and traditional students in tests given 1+
  semesters later.
Concerns with the Current Course At
  Santa Ana Community College
• Pass Rates

• Lack of Conceptual Understanding and Lack of
  the Ability to Apply the Concepts

• Students Having the Most Trouble are the Least
  Likely to Ask Questions or Seek Help from the

• Students Don’t Complete Assignments
       OLI Statistics Course
• Focus on Conceptual Understanding Instead
  of Computation

• Rich with Interesting Applications

• Hands-On Assessments with Feedback

• Supports the Use of Minitab Software
            What I’m Finding
• Takes Time to Acclimate Students

• Students Resist a Change in Teaching Style from
  Teacher-Centered to Student-Centered

• Students Need to be Shown How to Self-Assess
  their Understanding

• Takes Time for Other Faculty to Buy-In to
   How I’m Adapting the Online

• Using Tutor Tools to Write Assessments

• Modified Course from just ―Did I Get This?‖ to
  ―Did I Get This Yet?‖
   How I’m Adapting the Course
• Adding Daily Problems Based Upon Student

• Adding Weekly Additional Problems for
  Students to Complete on Their Own

• Adding More Lab Activities Without Automated
 Additional Examples Of Re-use
• CSU – Stat course replace textbook and Lecture
  – use class time for collaborative lab work.
• A US virtual high school - AP Stat
• A small US medical school - second year
  graduate students
• University in Qatar – StatTutor supplements intro
  stats – cultural adaptation translation
• University in Colombia – combine OLI Statistics
  and CSR – redesign quantitative methods
• CSU – Replace textbook in large lecture course
  – rewrite exercises to create version in ―R‖
―Improvement in post-secondary education will
require converting teaching from a ‘solo sport’ to
a community-based research activity.‖
