| Because of the progress of modern technology, graphing calculators is a cheap, convenient and powerful learning for mathematics and science. It is more possible that students have calculators than that students have computers because of its prices. With powerful operation and graphing abilities, it is important to introduce and integrate graphing calculators to students for their mathematics learning, including analyzing data using tables, graphics, and operations. NCTM (1989) suggested that appropriate calculators should be available to all students at all times when they learn mathematics. Hence, it is important for teachers to learn how to integrate and use graphing calculators into their instruction in order to empower their teaching. | |
