| Abstract: | Summary This article describes how a teacher changed her method of teaching after acquiring knowledge about graphing calculators in a Professional development program. It describes one particular unit on understanding variables and graph interpretation taught in a seventh-grade science and math class. The use of graphing calculators proved to be effective in increasing student understanding of relationships between variables, graphing, and experimental design. The teacher in our project also found graphing calculators to be effective tools for teaching constructively. Our study implies that math and science teaching can be improved through the use of graphing calculators. |
