Pascarella, Bohr, Nora and Terenzini, (1995) Journal of Higher Education

slide10

Example of cross sectional model

  • VSA
  • ACT Linkage report
linkage model
Linkage model
  • Uses ACT scores as a covariate
  • Develops conditional distribution of CAAP scores given ACT score, based on a large sample
  • Compares institutional distribution with comparison distribution (based on deciles)
what s next
What’s next?
  • Assessments of a different type

(non multiple choice)

  • Standardization of alternative measures

(alternative assessment types, portfolios, college GPA)

example of what is possible
Example of what is possible
  • Bassiri and Schulz (2003) Constructing a universal scale of high school course difficulty
international dreams
International dreams
  • Is there a PISA or a Bologna in our future?
  • Is college knowledge the same across the globe?
  • Are the populations in college the same?
