Multivariable Regression Analysis of Online Physics Success
  Location: HC 3040
  Date: Monday, Aug.1
  Time: 6:30 PM -7:00 PM
  Author: Erik Jensen, Chemeketa Community College
  Co-Author(s): None
  Abstract: I used a multivariable regression to analyze success (grades) in six years of online and campus-based introductory physics classes at Chemeketa Community College. I analyzed independent variables including incoming GPA, grade in trigonometry, gender, age, home institution, and delivery method to determine their effects on success. I found that incoming GPA, home institution (Chemeketa students fared worse than outside students), and delivery method (there was an online "penalty" of about half a grade) significantly impacted success while other independent variables did not. In addition to presenting the multivariable regression analysis, I will provide both evidence of academic honesty and evidence that my students conduct substantive labs at home; these appear to be points of considerable skepticism among physics educators. I will also provide data and practices regarding retention, a challenge for any class with any delivery method at a community college.
