Margaret Heritage is an independent consultant in education. For her entire career, her work has spanned both research and practice. In addition to spending many years in her native England as a practitioner, a university teacher, and an inspector of schools, she had an extensive period at UCLA, first as principal of the laboratory school of the Graduate School of Education and Information Studies and then as an assistant director at UCLA’s National Center for Research on Evaluation, Standards, and Student Testing. She has also taught in the departments of education at UCLA and Stanford. Her recent books, both coauthored with Alison Bailey, are Progressing Students’ Language Day by Day (Corwin Press) and Self-Regulation in Learning: The Role of Language and Formative Assessment (Harvard Education Press).
E. Caroline Wylie is a research director at Educational Testing Service. Having completed her preservice teacher education with a focus on mathematics in Belfast, Northern Ireland, her focus shifted to classroom-based research. Those interests include issues related to balanced assessment systems, with a focus on the use of formative assessment to improve classroom teaching and learning. She has led studies related to the creation of effective, scaleable, and sustainable teacher professional development focused on formative assessment; on the formative use of diagnostic questions for classroom-based assessment; on assessment literacy; and on the role of learning progressions to support formative assessment in mathematics and science. She is currently the principal investigator on a grant (funded by the Institute of Education Sciences) that is examining classroom observations with a formative assessment focus and the relationship between observations, feedback, and changes to practice.
