MATHMAGIC Mathematics on the Internet Don Cruser Mendocino High School dcruser@mhs. mendocino.k12. ca.us California State Framework Area: Mathematics Grade Level: 9-12 Length of unit: Ongoing throughout the school year Abstract: Using E-mail on the Internet, teams of students from different schools will collaborate in the writing of solutions to open-ended problems posted by MathMagic. Final solutions will be submitted for consideration and evaluation. This unit is designed for a one computer classroom. Produced in conjunction with the NASA K-12 NREN Partner School Program and the California Telemation Project I. INTRODUCTION TodayÕs students will live and work in the 21st century, an era dominated by a global economy, worldwide communication, and powerful computers. This is a world in which science and technology will influence all aspects of life, from health and environment to financial affairs, politics, and national defense. Mathematics is the foundation of this setting since technology has mathematicized the workplace and statistics have permeated public policy debates. Participating members of this biosphere will have to be prepared to absorb new ideas, to perceive patterns, and to solve unconventional problems. Mathematics education is in transition as it adapts to the changing needs of students. The use of calculators and computers has greatly reduced the former emphasis on computation and the mechanics of math. At the same time there is a greater demand for mathematical versatility, reasoning, modeling, confidence, persistence, and communication. The mathematics curriculum has moved to offering a wider variety of problems. It is still necessary to spend time on mastering basic skills with short exercises, but in addition, students work cooperatively on larger, long-term projects. Within the current educational literature these multi-dimensional problems are referred to as nonroutine, or open-ended problems. They are characterized by allowing for a variety of solutions that require the students to analyze and select a strategy. Of primary concern is the studentsÕ ability to demonstrate and justify their mathematics with written explanations, diagrams, charts, graphs, models, and symbolic notation. It is worth noting that this type of problem forms the major component of the newly developed CLAS test. The purpose of this unit is to connect with MathMagic through the Internet in order to incorporate nonroutine problems into the math curriculum. MathMagic is a K-12 telecommunications project developed in El Paso, Texas that provides a strong motivator for students to use computer technology while increasing problem-solving strategies and communications skills. MathMagic periodically posts open-ended problems into each of four categories (K-3, 4-6, 7-9, and 10-12). A student team pairs up with another team over the Internet to engage in an exchange of problem-solving dialogue. When an agreement is reached, one solution is posted for every pair. II. STUDENT OUTCOMES Students will: -- be able to use e-mail telecommunications. -- collaborate in the solving of problems. -- employ a variety of methods in problem solving. -- demonstrate, justify, and revise solutions. -- evaluate and create open-ended problems. III. ACTIVITIES 1. Teams Student teams, ideally with 2-3 members, will be formed within the class. 2. Registered or Unregistered? Since the registration fee is $12, there will be only one registered team each period to begin with, and only members of the registered team will engage in the e-mail communications. 3. Challenges The open-ended problems, or ÒchallengesÓ as MathMagic calls them, will be posted every 3 weeks. All teams will write a solution. 4. E-mail Once the problem is posted the registered team will write to other teams from another locality until they agree to become Net Team Partners (NTP). Messages at this stage are informal as students exchange information about themselves, their schools, and communities. The range for forming partnerships extends to the international level. 5. Collaboration The Net Team Partners will discuss problem solving strategies and collaborate in the writing of a solution to the challenge. Clearly, this situation creates a need for students to demonstrate, communicate, and revise their mathematics that cannot be duplicated when confined to the classroom. Final solutions will be posted with MathMagic. 6. New Teams New teams will be formed for each new challenge. Membership on the registered team will be rotated until every student has had the opportunity to participate in the e-mail collaboration. If there is enough interest then perhaps students will contribute to the formation of more registered teams. IV. ASSESSMENT All teams will produce and present to the class a final solution for evaluation and inclusion in the determination of a students grade. Grading will be based upon participation, peer review, and a holistic rubric model.
