Mathematics
Education Newsletter The Education Department
is thrilled to host this year's visiting international professor, Wolfram
Meyerhöfer, whose focus is in mathematics
education. Dr. Meyerhöfer is from Germany, and is currently at the
Institut für Didaktik
der Mathematik of the Alpen-Adria-Universität in Klagenfurt, Austria. Before
moving recently to Klagenfurt, Dr. Meyerhöfer was a Guest Professor at the
Freie Universität in Berlin, and was an elected representative working in
government in Potsdam, Germany. This coming Spring, Dr. Meyerhöfer will be
teaching a seminar for graduate students in mathematics education, a course
in mathematics for undergraduates, and working with Arcadia students and
faculty to further infuse a global perspective in our programs and ongoing
projects. He will be visiting classes around campus to chat with students,
and will be available as an additional resource for your work should you be
interested in meeting with him.
Don't miss the opportunity to register for Dr. Meyerhöfer's Seminar for Mathematics Educators, ED 558B, which will focus on Dyscalculia and its problems as a lens through which to better understand making mathematics meaningful for all students.
Embracing Mathematics: On
Becoming a Teacher and Changing with Mathematics (Routledge, 2008)
is now available! See these links:
google books;
the publisher;
amazon. This alternative textbook and teacher discussion book for all
levels of mathematics education has been many years in the making, and most
recent graduates of Arcadia programs have had a hand in its ongoing
development, reading drafts of chapters, commenting, trying out the ideas,
and contributing their own action research stories themselves. Arcadia
mathematics educator authors in the book include Peter Appelbaum, David
Scott Allen, Isaiah Manzella, Karen Cipriano, Ada Rocchi, Colleen Murphy,
Kristen Iaccio, and Petal Sumner. David Kirchner of Louisiana State
University wrote, "This book is likely to have a substantial impact on the
landscape of pedagogical thinking. The pedagogy is a model for how to be
engaged in life, in this sense presenting a personal vision that informs
more than how to teach." Ole Skovsmose of Aalborg University in Denmark
wrote, "Embracing Mathematics presents a wealth of educational ideas.
It provides lenses for seeing classroom practice as open to fascinating
changes. Emerging as a powerful collective achievement, it provides a
dialogical opening of post-modern trends in critical mathematics education,
sees as practice, research, and as learning for everybody."
Isaiah Manzella, 2003 graduate of Arcadia in Special Education, and teacher at Rancocas Valley Regional High School in New Jersey, is this year's recipient of the Arcadia Alumni Teaching Award. Over the past five years, Mr. Manzella has taught Resource Center Mathematics, Inclusion Mathematics, Alternative School Mathematics, and now in a self-contained classroom for students with behavioral disorders. He also coaches soccer, co-runs the EA Sports Video Game club, and the Skateboard Club. He recently wrote about his experiences with his students in putting numbers on trial to prove their value in the book Embracing Mathematics (see above). Isaiah will receive his award during the annual Induction Ceremony for new Education students at the Castle, 7:00 pm, Tuesday, October 14th.
November 11th
- Tuesday - Jacqueline Leonard, Temple University, speaking on: Dilemmas of
Culturally Relevant
Pedagogy. This
presentation focuses on culturally relevant pedagogy and its nexus with
student learning in K-12 classrooms. According to Gloria Ladson-Billings,
culturally relevant pedagogy empowers both teachers and students to be
self-directed and to take charge of their own learning by using
circumstances that arise in the community as forms of official knowledge.
Specifically, the presenter examines how two high school teachers enacted
culturally relevant practices and how these practices influenced diverse
students’ opportunities to learn mathematics. The presentation will focus on
the complexities of implementing culturally relevant projects and some of
the dilemmas that arose in the two teachers’ classrooms. Concerns about
accountability influenced the teachers to attend more to mathematics content
than meaning-making and cultural competence. The presentation will conclude
with a discussion and suggestions about how to make mathematics lessons are
more relevant to the lives of diverse students and how to motivate them to
learn mathematics by making connections to social justice.
February 9th - Monday - Gordon Williams, Ursinus College, speaking on: Breaking the Da Vinci Code. Dan Brown's international best seller The Da Vinci Code has spawned an industry of conspiracy theories, historical television programming, and a movie. Hidden within this tale are some startling claims about the ancient Greeks, classical art and mathematics. In this talk we explore a wide range of the mathematically related claims made by the author and shed some light on those claims which are true, and those which are fiction.
February 19th - Thursday - Sorelle Friedler, University of Maryland, speaking on: How do Computers Solve Geometric Problems? Computational geometry is the study of computer methods to solve geometric problems and the study of geometric problems arising from computer applications. This presentation discusses some classic computational geometry problems, such as Voronoi diagrams and Delaunay triangulations, and ways they can be presented to high school students. These new geometric problems have many applications, from fire engine routes to video animation, and can be added to a high school geometry curriculum to motivate and challenge students.

Mitch’s Corner
Mitch's Corner is a regular feature of the
Arcadia mathematics Education Newsletter, sharing samples of resources from
Mitch Bernstein, a high school math in

Here is one of Mitch’s famous Problems of the Week:
Assume a cable was strung around the earth on poles at the equator. The cable is 50 feet longer than the circumference of the earth at the equator.
Could a man walk underneath the cable after it has been strung?Explain your answer.
Your Advisor☺
Peter Appelbaum has official office hours Tuesday 3-5 and Wednesday 2-4, and is also available for appointments with graduate students on other days of the week.. Call or email because he will likely be in and out of the office most days. 215-572-4476 or appelbaum@arcadia.edu.
Mitch’s Corner Solution
Yes!
Assume that the Circumference of the earth at the equator is C. Since C = 2π r , and r = the radius of the earth.
To increase the circumference of the earth by 50 feet, the radius would have to increase also. Let x = the increase in the radius of the earth.
Then
2π(r+x)=C+50 feet. By the distributive property, we get2πr +2πx=C+50 feet. And since
2
π r = C, then
2π x = 50 feet and
x
= 50/2π feet.
Using 3.14 for
π,x ~ 50/6.28
or, 7.96
feet.
This means that the cable is suspended approximately 8 feet above the ground and most people could walk under it.
