High failure rates in introductory college mathematics courses, particularly among underrepresented groups of students, have been of concern for many years. One approach to the problem experiencing some success has been Treisman's Emerging Scholars workshop model. The model involves supplemental workshops in which students solve problems in collaborative learning groups. This study reports on the effectiveness of Math Excel, an implementation of the Treisman model for introductory mathematics courses (college algebra, precalculus, differential calculus, and integral calculus) at Oregon State University over five academic terms. Regression analyses revealed a significant effect on achievement (.671 grade points on a 4‐point scale) favoring Math Excel students. Even after adjusting for prior mathematics achievement using linear regression with SAT‐M as predictor, Math Excel groups' grade averages were over half a grade point better than predicted (significant at the .001 level). This study provides supporting evidence that programs like Math Excel can help students in making a successful transition to college mathematics study.

Efforts at inclusion and mainstreaming are pervasive in classrooms across North America. One of the many special populations formerly segregated but currently mainstreamed includes blind or partially sighted students. In this article we discuss some of the challenges faced by blind and visually impaired students and some of the tools available to help these students in their efforts to learn mathematics.

Women continue to be disproportionately underrepresented in science and engineering fields. A model for career choice is proposed that includes both the direct and indirect effects that socializers can play in determining career choices. A sample of 2213 high school seniors from nine schools in Rhode Island were surveyed about their academic and career choices and the perceived influences on those choices. Parents and teachers were perceived to be influences on career choice more often for students (both men and women) choosing careers in engineering and science than for those not choosing such careers. Pay was a more important factor in career choice for men in general, and genuine interest was a more important factor for women not choosing careers in engineering or science. However, these gender differences do not appear among students with extremely strong mathematics and science coursework backgrounds, even though there remains a marked disparity in the proportion of men to women planning careers in engineering or science. Teachers may play a particularly important role in influencing the career choice of some of these women. Equity of access and encouragement in mathematics and science is certainly a necessary, but insufficient, condition for improving the representation of women in science and engineering.

Recently, a colleague in our department shared a version of this problem with us. Since then, we have had a great deal of fun with it, provoking considerable debate among students, teachers, and mathematicians alike. The problem involves introductory probability concepts, and we have found it appropriate for, and interesting to, students from middle school to college.
