Alan Henry Schoenfeld (born July 9, 1947) is  an American mathematics education researcher and designer. He is the Elizabeth and Edward Conner Professor of Education and Affiliated Professor of Mathematics at the University of California, Berkeley.

Education and career
Schoenfeld was raised in New York City, studying at Queens College (BA 1968) before moving to Stanford University in order to research in pure mathematics (MS 1969, Ph.D 1973 on topology and measure theory). During his graduate studies he became increasingly interested in the teaching and learning of mathematics, particularly of non-routine problem solving. He taught at University of California, Davis (1973–5), University of california, Berkeley (1975–78), Hamilton College (1978–81) and the University of Rochester (1981–1985) before moving back to Berkeley where he now works.

Research
Schoenfeld's work ranges widely across thinking, teaching, and learning in mathematics and beyond, with particular interest in methodological issues aimed at improving the effectiveness of educational research. He has written, edited, or co-edited twenty-two books and more than two hundred articles on thinking and learning. He has focused successively on three major areas:

On problem solving. He made an empirical study of how far mathematics undergraduates tackling non-routine problems can use the strategies set out in George Polya's work How to Solve It The strategies were based on Polya's reflections on how he solved problems. Schoenfeld's study found that the strategies alone are weak, and need to be strengthened by complementary domain-specific tactics. He also showed the importance of students' monitoring their work on a problem and adjusting their tactical and technical moves accordingly.  This work was published as Mathematical Problem Solving (1985).

On models of teaching. Understanding the decisions that teachers make in real time in the classroom then became a focus. From the analysis in great detail of videos of mathematics lessons, he and his collaborators developed a model of teaching emphasising three key dimensions – the teacher's knowledge, goals and the beliefs about mathematics. He later generalized the work to real time decision making by professionals, published as the book How we think (2010).

On improving classrooms. Since the 1990s Schoenfeld has become increasingly focused on the challenges of translating research insights into tools and processes that improve teaching and learning in real world classrooms. Working with the design team at the Shell Centre for Mathematical Education. in Nottingham, he has led projects to develop tools for teaching and assessment, culminating in the Mathematics Assessment Project. Complementing this he developed a theoretical framework, Teaching for Robust Understanding (TRU), a model of classrooms in which productive learning is likely to occur. This identifies five key dimensions: the Mathematics; Cognitive demand; Access; Agency, authority and identity; Formative assessment.
