The case of the Case of Benny: Elucidating the influence of a landmark study in mathematics education

摘要

Stanley Erlwanger's Case of Benny is seen by many as particularly influential in the mathematics education research community. This paper reports the results of a study designed to describe the nature of that influence. Through an analysis of academic references to the Case of Benny from the past 40 years, five primary purposes for citing the case were identified. These purposes revolve around the themes of student mathematical conceptions, the relationship between correct answers and understanding, the value of qualitative research, the impact of a behaviorist-based curriculum, and students as sense makers. The paper concludes by using these themes to reflect on the past 40 years and to look ahead to the future of research in mathematics education.
