Middle school algebra students (N = 125) randomly assigned within classroom to a Problem-solving control group, a Correct worked examples control group, or an Incorrect worked examples group, completed an experimental classroom study to assess the differential effects of incorrect examples versus the two control groups on students' algebra…

Since 1995, the Buck Institute has partnered with university economists and expert teachers to create the Problem Based Economics curriculum. The curriculum was developed to respond to NCEE (National Council on Economic Education) standards, and it is supported by professional development for teachers. This study examines whether the Problem Based…

Researchers in both cognitive science and mathematics education emphasize the importance of comparison for learning and transfer. However, surprisingly little is known about the advantages and disadvantages of what types of things are being compared. In this experimental study, 162 seventh- and eighth-grade students learned to solve equations (a)…

This study examines whether the Problem Based Economics curriculum developed by the Buck Institute for Education improves grade 12 students' content knowledge as measured by the Test of Economic Literacy, a test refined by the National Council on Economic Education (NCEE) over decades. Students' problem-solving skills in economics were also…

This paper explores the development of students' knowledge of mathematical procedures. Students' tendency to develop rote knowledge of procedures has been widely commented on. An alternative, more flexible endpoint for the development of procedural knowledge is explored here, where students choose to deviate from established solving patterns on…

A study investigated the effects of direct instruction in the process of revision on students' knowledge of the revision process, their ability to make revisions on paper, and the quality of their writing. Subjects, 30 sixth grade students, were divided into an experimental and a control group. The experimental group received instruction in the…
