Why Assessment Results Are Hard to Use (and what to do about it)
Choosing an Achievement Scale Pick a scale that corresponds to the educational progress we expect to see. Example: 0 = Remedial work 1 = Fresh / Soph level work 2 = Jr / Sr level work 3 = What we expect of our graduates
Subjective measurements • Use authentic data that already exists • Sacrifices reliability for validity • Create subjective ratings in context • Sacrifices reliability for validity • Assess what you observe, not just what you teach! • Recovers some reliability For complex goals like general education: www.coker.edu/assessment
Survey Attitudes and Behaviors • CIRP, BCSSE, Student satisfaction inventory • Link student ID numbers to other indicators • These can be easily and productively outsourced
Some Tools • ANOVA • Logistic Regression and ROC curves • http://statpages.org/logistic.html • Pivot tables
Use data you already have • Grades • FAFSA, SAT, ACT items • Demographic data • ePortfolio statistics or work • Library circulation statistics
You don’t have to average • Measurement requires: • Units • Ability to aggregate • What we actually do is estimation • Without measurement we shouldn’t average
Conclusions • Design it yourself • Use a sensible longitudinal scale • Combine with other data • Avoid averages
