Accurate and accessible expressions for the probability of having a matching birthday are obtained by using Stirling's formula and Taylor series. For interest, the results are applied to the planets of our solar system.

This article explores how different proofs of a solution to the Surfer Problem provide answers to the question "Why"?

This article describes a solution, using CAS, to graph theory problem that was presented in the movie "Good Will Hunting."

This study assessed the effects of small-group tutoring with and without validated classroom instruction on at-risk students' math problem solving. Stratifying within schools, 119 3rd-grade classes were randomly assigned to conventional or validated problem-solving instruction (Hot Math, schema-broadening instruction). Students identified as at…

Teaching mathematics to students with emotional and behavioral disorders (EBD) is one of the most challenging tasks educators face today. Students with EBD are reported to have the most dismal outcomes of any other group of students with disabilities including the lowest grades, the most failing grades, higher retention rates, the highest dropout…

Based on the notions of social and socio-mathematical norms we investigate how these are established during the interactions of pre-service teachers who solve mathematical problems. Norms identified in relevant studies are found in our case too; moreover, we have found norms related to particular aspects of the problems posed. Our results show…

This article discusses the 4-H Gateway Academies specifically designed to enhance science, technology, engineering, and math (STEM) skills and knowledge in middle school youth. The innovative summer day camps partnered Project Lead the Way--trained teachers with county 4-H staff from University of Wisconsin-Extension (UW-Extension) Cooperative…

This research describes preservice teachers' perceptions of the use of applets in solving mathematical problems. It examines such perceptions regarding the role and functions that applets have in the problem solving context, the difficulties they encounter when using applets in this context and the necessity or need of their use. I attempt to…

As part of an on-going project designed to impact teacher quality at the pre-service, induction, and professional development levels, this paper summarizes the parametric results of a series of four different workshops conducted in the summer of 2007. In an effort to glean a better understanding of their knowledge, attitudinal, perceptual, and…
