Opening Keynote, Monday, October 12, 9:15 a.m.

Shepard is a Distinguished Professor of Research and Evaluation Methodology and Dean of the School of Education at the University of Colorado Boulder. Her research focuses on psychometrics and the use and misuse of tests in educational settings.

In her keynote presentation, Dr. Shepard will summarize what should be the same and what should be different in the design of classroom-level and large-scale assessment, focusing on the specific examples of formative assessment in classrooms and then on large-scale accountability testing. She will propose strategies for designing linkages between the two so that learning gains in classrooms, enabled by formative assessment, will also lead to authentic improvements in performance on large-scale assessments.

To fit the conference’s theme, Shepard’s examples will illustrate why validity evaluations, like test design, must be focused on the intended use of the test. Considerations of similarity between the two will be presented, starting with domain specifications or learning progressions, but, ultimately, she will demonstrate why much must be different.
