I recall recently being out walking on a Sunday morning. Three kids about age 8 or 9 were roller blading. They saw a narrow width open concrete drain going down into a depression in the ground. The kids decided to try going down the drain on their roller blades. One youngster was the gutsy one, and after he made it safely, his two more hesitant buddies gave it a whirl, and they did fine, too.

One of the kids noticed a small mound of earth at the bottom of the incline where the drain ended. He decided to try to leap over it on the next try down the drain. As I watched, I read a little fear creep over his face, and I overheard worry in his voice as he explained to his companions what challenge he was about to assume. Then he summoned his nerve, and his partners and I looked on as he speeded down the track. He jumped and cleared the mound with room to spare. His friends took up the challenge, and they succeeded, as well. To increase the challenge, one of them decided to try to build the mound higher. He would have accomplished that goal if the dirt had been easier to dig and if it had been moister to pack together.

At this point, I started a little conversation with the kids. I told them I had always wanted to try those roller blades but that I was worried I'd get hurt. One of the youngsters told me not to worry, that his dad rode the blades, and his dad was 37. I told him I was 48, and the youngster sought to allay my fears or bolster my courage by saying that I was only 11 years older than his dad. Well, enough visiting had taken place, except for my question about what the young man was planning to do next.

He said he was going to do a 360. I asked him to explain, and he said that was a circle in the air. So then he took off and leaped into the air as he left the bottom of the drain. He landed smoothly, and when he returned to the top, I asked him what had happened. He reported he hadn't made it. What he said he'd done was to make it only part way around. He said he had only done a 180! So I asked him to tell what he might do to make the 360. He thought a moment and said if he'd jump higher, he'd have more time in the air to spin, and that's how he'd do the 360 next time. Well, I didn't get to see next time because he and his friends spied a wonderful pipe structure they wanted to examine and explore. So, off they went.

Those kids left me with this story that I think is just a wonderful example of naturally occurring mathematics. There's a world of informal mathematical experience just lying dormant. Many kids have such experiences as these, and a route to elaborate mathematical understandings would be so profitable through this territory.

**Be it resolved that: **the Board of Directors reconstitute a committee to work with international
issues of mathematics education.

Rationale: North American mathematics education cannot stand alone in the world. There is much we can learn and much we can contribute by reaching beyond our borders to the world mathematics education community. The committee can facilitate such outreach by establishing formal links and encouraging informal ties to mathematics education organizations and individuals in other countries. This can strengthen the role of NCTM in international committees, encourage exchange of curricular and instructional ideas, assist researchers in gaining a more global view of mathematical experience, and help build a broader viewpoint for North American teachers and students. Administratively, this committee could also provide a base for international affiliated groups and participation in the International Commission on Mathematical Instruction.

**Be it resolved that: **the Board of Directors establish a Joint Committee on Mathematics and
Culture.

Rationale: NCTM is in a position to provide important encouragement and assistance to efforts to consider increased use of culture in the school mathematics curriculum. This is in keeping with the Standards' call for more mathematical connections. Culture in this context includes examples of mathematical contributions and applications from around the world, uses of mathematical ideas of various age groups, special needs of mathematics by occupational groups, and other cultural groups broadly defined. This also includes the culture of mathematics: historical examples; math in the arts; classic puzzles, games, and problems of math; and other areas of potential curricular enrichment. Note that this committee's scope complements but does not overlap that of the current Committee for a Comprehensive Mathematics Education for Every Child; the existing committee is more concerned with equity issues for underrepresented groups. The proposed committee would be concerned with encouraging a broader mathematics curriculum for all students, drawing more naturally upon the needs of the learners than the traditions of the profession.

[Note: It would be expected that the joint committee would include members from several of the affiliates that are concerned with mathematics and culture.]

To accompany the series, WGBH is launching a comprehensive and integrated outreach project
targeting youth leaders, as well as social studies, English and science teachers and the students
they serve. Central to the national outreach campaign is the **S.O.S. - Seek Out Science** initiative. This motivational project is designed to spark junior high and middle school students'
interest in science, broaden their understanding of what science is, and create connections
between young people and the women working in the sciences in their own communities.
Through the process of researching and interviewing women scientists, students will learn about
the lives, work, and struggles of these women. These projects will break down students' stereotypes of what it means to be a scientist by opening their eyes to a vast array of experiences and
life stories.

A 16-page, multi-disciplinary *S.O.S. Activity Guide* will provide information about the television
series and will offer how-to information for teachers and youth leaders about the S.O.S. project,
which will run through April 1995. All students participating in the initiative will receive a
recognition award from WGBH for work. More importantly, their work may be included in a
Discovering Women/Seek Out Science exhibit at one of eight demonstration sites. Sites will be
located throughout the nation, primarily at science and children's museums. Each demonstration
site will create a unique display of the students' work, including an interactive database of every
students' findings, and generate publicity around the exhibit during the summer and fall of 1995.

December and/or your local PBS station does not have copies write to:

Bockarie, Alex. **Mathematics in the Mende Culture: Its General Implication for Mathematics Teaching**. *School Science and Mathematics*, v93 n4, April 1993, pp. 208-11.

This article discusses the Mathematics that exists in the Mende culture, an African tribe in Sierra Leone, includes counting, computation, fractions, ratios, forecasting games, and mathematical applications. It discusses the Mende representations of these concepts and discusses implications of their integration into mathematics teaching.

Boaler, Jo. **The Role of Contexts in the Mathematics Classroom: Do They Make Mathematics More "Real"?**, *For the Learning of Mathematics*, v13 n2, June 1993, pp. 12-17.

Boaler suggests that contexts may be useful in mathematics instruction in relation to learning transfer and that the factors that determine whether a context is useful are complex. She discusses the context effect, learning in context, how well students identify with tasks taken out of an adult world, and the effects of ethnomathematics.

Knijnik, Gelsa **An Ethnomathematical Approach in Mathematical Education: A Matter of
Political Power**. *For the Learning of Mathematics*, v13 n2, June 1993, pp. 23-25.

Knijnik presents two practices used by rural Brazilians to estimate area of land and volumes of tree trunks. In the context of the struggle for land and using an ethnomathematical approach, she develops educational ideas involving the interrelations between academic, school-based mathematics and popular ethnomathematical knowledge. She also discusses contributions of this work to the process of social change.

Lipla, Jerry. **Culturally Negotiated Schooling: Toward a Yup'ik Mathematics**, *Journal of
American Indian Education*, Spring, 1994, pp. 14-20.

This paper describes one aspect of a long-term collaboration between the author and a Yup'ik
teachers' research group, *Ciulistet*, focusing on the processes and development of Yup'ik
culturally based mathematics. The premise behind this work is that the Yup'ik language, culture,
and worldview, particularly subsistence activities, contain mathematical concepts. These
concepts include a number system that is base 20 and sub-base 5, and ways of measuring and
visualizing. This has direct application to school math. However, just as important, the project
participants are increasingly realizing the potential of using their culture and language as means
to change the culture of schooling.
