### Mathematics

#### Technology

The TI-89 graphing calculator is one of the most powerful calculators on the market today. This amazing calculator can do any kind of math and solve all sorts of problems. It's useful for programming, graphing in 2D and 3D, solving multi-step problems, and almost anything else that you need it to do. This calculator is great for math students because they can solve a greater number of problems with a greater complexity than ever before, Visualizing 3D graphs becomes possible with this graph enhancing students' knowledge and understanding.

Another really useful technology tool, especially in geometry classes, is Kig. Kig stands for KDE Interactive Geometry.  It is free and open source interactive geometry software. It is free as in it doesn't cost anything, and it is also free like free speech. It is meant to be a better replacement for other similar software, and a free alternative to Geometers' Sketchpad (Spencer Kingman).

Students and teachers alike will find it exceedingly easy to use Kig to explore geometric constructions, from the most minimal Platonic problems to more modern problems like congruence transformations. The interface is pleasant, simple, and very visual. Teachers can also use Kig as a WYSIWYG tool to draw mathematical figures, instantly, and with far more precision than they could ever hope for at the chalkboard. Once drawn, figures are easily labelled, colored, moved, manipulated, saved, printed, or published to the web (SK).

KDE for Windows is in development, so Windows users should be able to run Kig shortly. Also there are other similar programs that are compatible with Windows or Mac OS (SK).

Maple
Maple is perhaps the most powerful software application for mathematics available.  It can analyze data, create graphs, perform complex calculations, and more.  One way it can help further understanding for students is be creating and simulating graphs of 3D functions.  Being able to actually see the graph, rotate and move it around, and look at if from various angles will help to further students understanding of these complicated functions and their behavior.

This software can be used in the classroom to help students visualize geometric problems. It is very dynamic and easy to use. If students like the sofware and have an interest in using it there is a student version available as well. To get an idea of how this program works here are 101 Project Ideas which show how to effectivly incorporate it into your classroom. Here is a website for video tutorials on sketchpad. (Kolby Gadd)

ResponseCards
ResponseCards can be used so that we can anonymously record where the class stands as a whole on the topics.  By using these for exit exams I will be better able to analyze the class as a whole and can know what material I need to cover more and what is known clearly. Video Tutorial, More Information on how to properly use this material visit this link Integrating Technology. (Ashley Stark)

AutoCAD is a great program to help students draw blueprints for houses, roads, etc.  This program would be a great tool to use for geometry and pre-calculus.  The software is expensive, however, it can be purchased.  Here is a tutorial for AutoCAD and a video demonstration of what is made possible with AutoCAD.

Chaos Pro

ChaosPro is a real time freeware fractal generator for MS Windows with support for many different fractal types (2D and 3D), true color support, animation support. Due to its integrated compiler it is quite fast even if you write your own formulas within ChaosPro. (R Maxfield)

#### Video Demonstration

Here is a video tutorial showing the basics of programming the TI-89 calculator.

This video shows some of the many ways Maple Software can be used in Math Education. (Devin Weaver)

A very nice video, showing how to create a fractal. (R Maxfield)

#### Summary

Mathematics in Secondary schools encomposes everything from 7th grade math to AP Calculus and everything in between. The goal in teaching mathematics to students throughout these years is to help them learn basic mathematical skills and concepts and then build upon those so that they build understanding in logical reasoning, problem solving skills, and application of mathematics.

Technology is used in mathematics throughout these classes to enhance students' understanding, create meaningful learning, and help them learn to use the tools that are available to them for all mathematical purposes not only for their future school work but also for their everyday lives and future careers.

Mathematical ideas are usually written in a language that is rigorous, formal, and symbolic. This language is sometimes confusing to students, but computers love it! There are two primary benefits of technology in the mathematics content area. The first is computation.  Computers and calculators render some of the complex procedures of mathematics effortless. The second is visualization. Computers also allow us to create precise, flexible, and dynamic graphical representations that are simply not possible with a chalkboard or pencil.

#### Tutorials

Visit the TI-89 Calculator Tutorials for using the calculator in mathematics. (Amber Holdaway)

Visit this page for a tutorial that will help you get started with Kig. Also the Kig Handbook has plenty of information (Spencer Kingman).

This is a great tutorial to learn 3-D Transformations for ChaosPro for fractal generation. (R Maxfield)

Teachnology for Mathematics is a great website for teachers to keep update about the uses of mathematics in education. Including links to other sites and articles with ideas for their classrooms. (AH)

If you want to stay really up-to-date on technology news, don't just wait for a editor to publish somewhere. Join an online group or listserv. The Math Forum at Drexel hosts one called math.teaching.technology. The Math Forum is a great website, but it appears that not too many people are posting on this listserv. There are also blogs. Here's one that I found: teachingcollegemath.com. (SK)

Here is a math teacher who frequently uses technology in his math class in an interesting way. This water tank lesson is from the What Can You Do With This series. (Kolby Gadd)

Visit the following site for more examples on how to incorporate technology into math curriculum. Integrating Technology. (Ashley Stark)

The Math Forum at Drexel is a very helpful and comprehensive website for Math in general.  Under the 'Resources and Tools' tab, there are a lot of ways to incorporate technology in math.  Aside from that there are ways to get help for various math topics, practice problems and puzzles, and more. (Devin Weaver)

NCTM.org is the place to go for math teachers concerning methods for teaching mathematics. (Spencer Saluone)

#### Articles

Here is an article on how AutoCAD can benefit a classroom. (Spencer Saluone)

Integrating Technology into the Mathematics Classroom- (Ashley Stark)

Great article on how to create fractals and what you need to do so yourself. (R Maxfield)
