Pearson TMRS Newsletter Bob Dolan ABSTRACT: The purpose of this chapter is to identify and discuss several
psychometric challenges and opportunities that we see related to formative
assessment now and into the future. We begin by sharing examples of
technology-based systems that combine instruction and assessment in ways that
promote formative uses of test data. We then relate these examples to the
current Standards and ask the questions, “How does one assess the
technical quality of assessments used for formative purposes?” and
“which new psychometric techniques will help improve the technical
quality of assessments to be used for formative purposes?” In
addressing these questions, we rely primarily on the fundamental concepts of
reliability and validity, which provide ample stimulation for considering the
role of psychometrics within a formative assessment system. ______ Bob
Dolan is a Senior Research Scientist in Assessment and Information at
Pearson. His work focuses on technology-based summative and formative assessment
with emphases on cognition, accessibility, and usability. Prior to joining
Pearson in 2007, Bob was a Senior Research Scientist at CAST, where his
research focused on designing, implementing, and evaluating advanced
technology-based learning environments that support diverse learners. Bob has
served as principal investigator on research projects funded by the National
Institutes of Health, the National Science Foundation, the U.S. Department of
Education, and private foundations. Over the past 25 years, Bob has pursued
parallel tracks in research and development in systems and cognitive
neuroscience, and the development and engineering of technology-based tools
for educational, scientific, and medical research. He received a B.S. in
Biology at Cornell in 1986 and a Ph.D. in Brain and Cognitive Sciences at MIT
in 1992. Psychometric Challenges and Opportunities in Implementing
Formative Assessment Denny Way, Paul Nichols and I just finished a book chapter
on the psychometric challenges and opportunities in implementing formative
assessment. I could talk about, and we could discuss,the applicability of
summative assessment-based psychometric concepts to formative assessment,
vis-a-vis validity and reliability. Host: Neil Heffernan Refreshments will be served.
