*A presentation for the Department of Mathematics,
University of Kansas, December 7, 2000*.

### Abstract

### Appropriate uses of technology tools
can enhance mathematics learning and teaching, support conceptual
development of mathematics, enable mathematics investigations
by students and teachers, and influence what mathematics is taught
and learned. This talk focuses on preparing mathematics teachers
to use appropriate technology tools into doing their own mathematics
and to incorporate appropriate technology tools into teaching,
learning, and curriculum. Demonstgrations with Geometer's Sketchpad,
Graphing Calculator 3.0 and Excel will be included.

# Introduction

###

### Good mathematics teaching, meaningful
reform, and genuine improvement of mathematics inststruction
will result only if it is manifested within mathematics classrooms.

### The role of the teacher is essential.

### The growing nearly universal availability of technology tools
provides a grand opportunity to assist teachers in teaching well
and in improving the mathematics experiences of students.

# What I will talk about

### Courses I teach for inservice mathematics teachers

###

# Potential benefits of appropriate technology
use

### Promote better mathematics learning.

### Build conceptual understanding

### Doing mathematics

### investigations

### problem solving

### applications

### exploration

### Communication within/about mathematics

### New look at some "old" stuff

### Doing mathematics not likely to be
encountered without technology

### Doing mathematics that incorporates
technology (e.g. iterations)

### Self-Confidence about one's mathematics

### Generative tools for constructing one's
further mathematics study.

### Minimum of 11 collegiate mathematics
courses including

### Calculus I and II. Sometimes multivariate
also

### Linear algebra

### Introduction to Higher Mathematics
(How to do proofs)

### Abstract algebra. Sometimes two courses.

### College Geometry. Somethimes two courses.

### Statistics

### Other upper division mathematics or
teaching field courses such as History of Mathematics or Problem
solving in Mathematics.

### Some knowledge of technology.
