The Effect of Graphing Calculators on Learning Mathematics

Because of concerns that use of graphing calculators might prevent math students from learning mathematical concepts, several researchers have performed studies on the effects of graphing calculators on learning.

Concepts Taught with Graphing Calculators

Graphing calculators can be helpful for teaching mathematical concepts such as permutations and combinations, divisibility rules for primes and components, functions and multi-step problems. Their use helps students understand the concept of a variable better and helps them use varying strategies to approach specific problems.

Positive Effects

Research done at Columbia College of South Carolina shows that use of graphing calculators played a part in improving developmental mathematics students' test scores, grades and attitudes about math. The National Council of Teachers of Mathematics issued a statement of support for the use of graphing calculators in 1986 because of research showing increases in students' number sense and development of mathematical concepts.

Negative Effects

Some research on the effects of graphing calculators in learning math contradicts the overall positive results. Studies done by Hembree and Dessart show that use of calculators doesn't have an overall effect on students' understanding of mathematical concepts. Furthermore, use of calculators can result in a negative effect on students' skills solving problems with pencil and paper. According to researchers Dunham and Dick, the mere presence of calculators does not help students learn math. Rather, the entire math curriculum must be redesigned to incorporate graphing calculators into the learning process.
