  • 19. Assessment: Pre and Post exams• Goal:  Substantiate learning of conceptual and numerical problems.  Satisfy SACS• Methodology:  Apply pre-test before a topic has been covered.  Cover topic in class, workshop, lab.  Apply equivalent post-test after topic has been covered.• Sample population: ~ 20 students U N I V E R S I T Y O F T E X A S A T E L P A S O

  • 21. Assessment: Standardized exams• Goal:  Quantify learning by comparison to a national sample• Methodology:  Use ETS standardized exams  Use exam as part of final exam  Compare to ETS’ national averages• Sample population:  Entire class (~200 students)  Excludes dropouts• Results not ready yet. U N I V E R S I T Y O F T E X A S A T E L P A S O
  • 22. Top challenges: Lecture• Improve initial background of students:  Students did not take high school physics• Add more value to lecture:  Make students study before coming to class• Increase attendance:  Is attendance needed?  Can WebCT replace in-person attendance?  Use daily quizzes?  Clickers? U N I V E R S I T Y O F T E X A S A T E L P A S O
  • 23. Top challenges: Workshop• Improve background of Peer Leaders  Reduce physics misconceptions• Improve preparation of PLs  Better pedagogy  Better workshop structure• Increase retention of PLs as PLs  Some last one or two semesters only U N I V E R S I T Y O F T E X A S A T E L P A S O
  • 24. 2+2 Program• Quantify effectiveness of 2+2 method  What metrics to use?• Guarantee future continuation of program  Sell idea to future faculty to implement program.  Convince administrators to support PLs after funding ends.• Specialized training of physics PLs U N I V E R S I T Y O F T E X A S A T E L P A S O
