[Online]. Accessed 4/15/01: http://forum.swarthmore.edu/ "Students need to construct their own understanding of each mathematical concept, so that the primary role of teaching is not to lecture, explain, or otherwise attempt to "transfer" mathematical knowledge, but to create situations for students that will foster their making the necessary mental constructions. A critical aspect of the approach is a decomposition of each mathematical concept into developmental steps following a Piagetian theory of knowledge based on observation of, and interviews with, students as they attempt to learn a concept." -- Calculus, Concepts, Computers, and Cooperative Learning (C4L) Math Learning Center (MLC) [Online].

Quoting from the Website:The Math Learning Center was formed in 1976 as an outgrowth of the Oregon System in Mathematics Education, a statewide experimental project to improve the teaching of mathematics. Three mathematics educators, with teaching experience ranging from grade six through university level, recognized the need to continue the work started under the project. Abandoning traditional education roles, they established an independent 501(c)(3) corporation to generate programs and advance ways of teaching and learning mathematics that enable each individual (a) to develop their mathematical abilities, and (b) to find joy in the processes of teaching and learning.

NCES constantly uses graphs and charts in our publications and on the web. Sometimes, complicated information is difficult to understand and needs an illustration. Other times, a graph or chart helps impress people by getting your point across quickly and visually. Here you will find four different graphs and charts for you to consider.

Quoting from the Website:Metacognition is thinking about thinking. Often when solving math problems, a solution or a means to one pops into our head so quickly that we don't know how we found it. It is not always easy to slow down our thinking, retrace the path of our thoughts and examine our hidden strategies. Doing so can help us to develop a set of strategies to try when we are utterly stumped. Weisstein, Eric. World of Mathematics [Online]. Accessed 4/4/02: http://mathworld.wolfram.com/.

## Middle School MathematicsShow Me Project [Online]. Accessed 7/15/01: http://showmecenter.missouri.edu/showme/project.html. A National Science Foundation project supporting implementation of standards-based middle grades mathematics curricula It focuses on five middle school sets of mathematics curriculum materials that were developed through NSF funding. One can explore each of the five curricula from the point of view of various topics, such as Technology. In general, the curricula make use of calculators, and some use computers. None aim for a deep integration of IT into the mathematics curriculum. Indeed, several note that the curriculum materials can be done without the technology.
## Secondary School Mathematics## Brief IntroductionSecondary school mathematics tends to be taught by faculty who have a keen interest in mathematics and who have had substantial formal coursework in the field. Since the National Council of Supervisors of Mathematics (in 1979) and the National Council of Teachers of Mathematics (in 1980) recommended the use of calculators in mathematics education, we have seen a slow but steady increase in the use of IT in secondary school mathematics. For example, the use of scientific calculators and graphing calculators is relatively common in secondary school mathematics. Calculator technology has led to changes in curriculum content, such as dropping the "by hand" computation of square roots from the curriculum, and students no longer learning to make extensive use of math tables. As notes in the Computer Algebra Systems part of this web page, very powerful tools exist for carrying out mathematical computations, manipulations, and procedures. Most schools are quite far from implementing routine use of such tools into their mathematics curriculum, instruction, and assessment. Project-based learning (PBL) (with roots lying in a constructivist approach to instruction and learning) has long been used in a variety of curriculum areas. IT-Assisted PBL is of increasing importance in all academic disciplines and grade levels in our educational system. Some math courses make use of IT-Ass sited PBL, but there is substantial room for growth in this approach to math education. ## ReferencesSpecht, Jim (2001) The Last Great Race: Using Technology to Support Math Instruction.

Quoting from the Website:Over the years, I've enjoyed using the Iditarod race in my math classes because it has been successful with all ability levels. I believe it would work at middle school, too. It conforms with the National Council of Teachers of Mathematics standards at many levels by appropriately using technology and addressing multiple learning styles with a variety of activities. As a teacher using the Last Great Race, I truly act as the facilitator, rather than as the dispenser of knowledge.
## Computer Algebra Systems## Brief IntroductionVarious functional components of today's Computer Algebra Systems (CAS) were developed on for mainframes and timeshared computers more than 30 years ago. Now, very powerful CAS is available for microcomputers, and systems of less power are available on some handheld calculators. Very roughly speaking, our formal educational system is faced by: - Very inexpensive, solar powered, 6-function handheld calculators that students can readily learn to use in elementary school.
- Calculators that can do what those in #1 can do, but also do arithmetic with fractions. These are suitable for students at the upper elementary school levels and above.
- Scientific calculators.
- Graphing calculators.
- CAS calculators.
- Microcomputers that can do all that items 1-5 can do, and more.
There has been quite a bit of research on the use of these tools in mathematics education. Research on simple calculators (and, their decreasing price) by 1980 led the National Council of Teachers of Mathematics to recommend their use even in the elementary school math education curriculum. Such calculators are now allowed by many states in their statewide assessments, and on a variety of national exams such as the SAT. Scientific and graphing calculators have become rather common in secondary school mathematics courses. The use of CAS calculators or computers at this level is slowly growing. Uses of CAS as a tool for learning and doing mathematics can be divided into the categories: (a) computation (b) visualization, (c) experimentation, (d) pattern-recognition, and (e) conjecture-forming. The references given below focus on CAS. ## ReferencesAsp, Gary and Kendal, Margaret (1999). Teaching Calculus

Calculus Reform [Online]. Accessed 7/15/01:
http://www.mste.uiuc.edu/murphy/ A history of the calculus reform movement is given, with emphasis on the roles of computers and computer algebra systems (CAS). The implications of CAS for the curriculum are considered. Early advocates of CAS in the calculus classroom stressed the opportunity to focus students' attention on concepts, with the computer taking on the burden of the algebraic manipulations that occupy so much time and attention in a traditional calculus course. Along with this change of emphasis comes the opportunity to alter the traditional sequence of topics in many ways, some of which are discussed here. In addition, CAS can be used to quickly create accurate graphs, allowing a more geometric approach to calculus. Calculus courses using CAS often involve much more student writing than traditional courses. Courses based on CAS generally use a constructivist approach, and frequently incorporate some form of cooperative learning. Evaluating these courses has been difficult because not only the methods, but also the goals, are different from those of a traditional course. Some of the evaluation techniques used by researchers are discussed. Evaluations comparing reformed calculus courses with CAS to traditional calculus courses generally favor the CAS courses, although there is some variation among CAS courses.
