[show]# IntroductionEdit

This article is aimed at providing math teachers with examples of successful implementations of technology, as well as a directory of relevant information.

The field of mathematics has benefited from technology throughout its history. Mathematical tools have advanced from the abacus and Quipu, an Incan base-10 counting system made of knotted fibers, to the calculators and computers of today. These tools can be used in the classroom to promote higher-level thinking and highlight the links between taught concepts and their real-world applications.

The range of instructional technology applicable to mathematics is vast, and at times, overwhelming. A multitude of hardware, software, and online offerings can be implemented in both conventional and novel ways to complement the many content, process, and technological standards of successful math instruction.

# RationaleEdit

Many benefits provide a sound Rationale for Technology in Education, including relative advantage, increased accessibility, cooperative grouping, exposure to new technology, interactivity, and differentiation.

In math, students can exercise higher order conceptualization to focus on "decision making, reflection, reasoning, and problem solving" (National Council of Teachers of Mathematics), such as by manipulating the variables of an equation and observing its effects on a graphing calculator. Instead of spending a significant amount of classroom time on computation, students can focus on higher level skills and useful applications of their newfound knowledge.

# StandardsEdit

### NCTM Standards for School MathematicsEdit

The National Council of Teachers of Mathematics (NCTM) places great emphasis on the use of technology in mathematics education. Technology, one of the six principles fundamental to school mathematics programs as outlined by NCTM's *Principles and Standards*, is "essential in teaching and learning mathematics; it influences the mathematics that is taught and enhances students' learning."

In the NCTM Standards for School Mathematics, NCTM outlines ten knowledge and skill objectives that should be achieved from prekindergarten through grade 12, including Numbers & Operations, Algebra, Geometry, Measurement, Data Analysis & Probability, Problem Solving, Reasoning & Proof, Communication, Connections, and Representation.gay

### ISTE National Educational Technology StandardsEdit

The International Society for Technology in Education (ISTE) publishes the 'National Educational Technology Standards (NETS)', a set of guidelines for the successful use of technology in education. Teachers utilizing technology in their instruction should assess their implementation by referring to NETS, detailed in the Rationale for Technology in Education.

# IssuesEdit

Despite the many benefits of technology in math instruction, Issues and Barriers to Integrating Technology exist that must be addressed. The greatest obstacles to technology in any field of education are funding and access. Teachers and students need access to the hardware and software before any useful application of the technology can occur, and teachers require professional development and construction time to utilize technology effectively.

Fortunately, the importance of technology as part of the classroom and beyond is increasingly recognized, and attention is being paid by school districts and educational organizations to the issues that stand in the way of technology in education. The following are issues specific to mathematics classrooms.

### Calculator DependencyEdit

Integrating technology into mathematics is not without controversy. Many educators fear that calculators and other technology will eliminate opportunities for students to sharpen their computational abilities. Teachers and students alike must use calculators as a tool rather than a crutch, as a means of extending math in new forms, exercising higher order thinking skills, and working more efficiently and accurately, without sacrificing an underlying comprehension of the concepts.

### AccessEdit

Technology is increasingly becoming an critical component of advanced high school math courses. E.g. students are expected to be proficient in the use of graphing calculators to solve problems efficiently. Additionally, calculator use is permitted on standardized tests such as the SAT and AP exams. As graphing calculators and other technologies become an integral part of the math classroom, care must be taken to provide

# Effective Uses of Technology in Mathematics InstructionEdit

### WebQuestsEdit

A WebQuest, as defined by creator Bernie Dodge, is "an inquiry-oriented activity in which some or all of the information that learners interact with comes from resources on the internet." WebQuests engage students in meaningful activities and have them apply new concepts to areas they find relevant.

View an example below, or choose from a wide selection of Best WebQuests or for math students in K-2, 3-5, 6-8, and 9-12.

- Following a unit on linear equations and with a primer on piecewise functions, students can go on the following webquest to analyze the cost-effectiveness of several real cellphone companies.

- 1. Navigate to the Cingular, Sprint, T-Mobile, and Verizon websites. Select the most basic personal plan that is offered and create a table that makes note of the monthly cost, included minutes, and cost per additional minute for each.
- 2. For each company, construct a piecewise function that represents monthly cost as a function of the number of minutes.
- 3. Graph the functions on a graph, with the number of minutes on the x-axis and the monthly cost on the y-axis.
- 4. Consider the following questions and write an essay explaining your findings. Include your data table and graphs, in addition to any additional supporting evidence.

- What does it mean when a company's graph is above another's?
- What occurs at the point where two companies' graphs intersect?
- Is one single company the most cost effective overall or does it depend on the number of minutes used per month?
- Examine a sample cellphone bill, either provided by your parent or the teacher. How many minutes were used in the past month?
- Compute the cost under the basic plan of each cellphone company. Which is the most cost-effective?
- What factors besides cost can be considered when choosing a cellphone company?

### Presentation TechnologiesEdit

Randy from EDTECH shares that the must-have technologies in his classroom start with presentation hardware and software, including a laptop, a digital document camera, a presentation system, mimio whiteboard, TI SmartView graphing calculator emulator, and Geometer's Sketchpad. View a video of some of these technologies in action at Annenberg Media Learning Math.

### Distance LearningEdit

Distance learning may be the best solution for students in a variety of circumstances, including those in rural areas, interested in remediation or acceleration, home-schoolers, and students whose home lives prevent them from attending school. With an internet connection, students have a link to the outside world from their computers, with which they can attend online lectures, complete assignments, and communicate with tutors via online whiteboard.

A number of universities and other organizations offer distance math courses for students in K through 12, including the Center for Talented Youth at Johns Hopkins University, NetMath at the University of Illinois, the Education Program for Gifted Youth at Stanford University, and Larson Math.

### Real World Problem SolvingEdit

Math students can be tasked with solving problems relevant to their school or community. Art from the EDTECH mailing list provides examples of how when the school district was searching for location for a newbus. math is hard to do. dont do meth do math it ruins your life twice as much. bus garage and retrofitting a school with air conditioning, students used contractor information, mapping websites, drawing programs, geometry, and trigonometry to find and support their own solutions.

### Emerging TechnologiesEdit

Emerging Technologies such as Weblogs, Wikis, and Podcasts can be utilized with great effectiveness in a math classroom. Darren Kuropatwa's blog A Difference chronicles his Applied Math, Precalculus, and AP Calculus classes as they participate in reflective writing, homework collaboration, textbook authoring, online classes, and podcast publishing.
