Appropriate uses of technology can foster students' understanding of
concepts in geometry and measurement. Technology can also assist the
teacher in adapting to the needs of special students. On the other hand,
use of inappropriate technology or ill-planned use of the technology can be worse for students than using no technology. A computer program that is too sophisticated for the students will only frustrate them. Using the computer for nothing more than drill and practice does not take advantage of technology's strengths.
Software such as Logo (turtle graphics) and MicroWorlds™ allow teachers to create activities and pose problems that encourage students to learn mathematics in the context of a problem. For example, students can use geometric concepts to create a house or other shape. Simulations allow students to explore topics they may not be able or willing to do on their own. Students may be able to explore with virtual manipulatives in a way that would not otherwise be possible. Software such as the Geometer's Sketchpad allows students to explore shapes like triangles and quadrilaterals in a dynamic environment. Students can also use the software to transform a figure, helping students to understand geometric transformations. Using the software to measure lengths and areas allows students to explore the concepts of area and perimeter. In addition, using calculators can allow students to focus on conceptual understanding and mathematical reasoning rather than solely on computation.
