Criticism of traditional mathematics instruction originates with advocates of alternative methods of instruction, such as
Reform mathematics. These critics cite studies, such as The Harmful Effects of Algorithms in Grades 1–4, which found specific instances where traditional math instruction was less effective than alternative methods. Advocates of alternative methods argue that traditional methods of instruction over-emphasize memorization and repetition, and fail to promote conceptual understanding or to present math as
creative or
exploratory. Critics also sometimes cite the fact that
history of mathematics often focuses on European advancements and methods developed by men, thus ignoring equity issues and potentially alienating minorities and women. The general consensus of large-scale studies that compare traditional mathematics with reform mathematics is that students in both curricula learn basic skills to about the same level as measured by traditional standardized tests, but the reform mathematics students do better on tasks requiring conceptual understanding and
problem solving. Critics of traditional methods note that only a small percentage of students achieve the highest levels of mathematics achievement such as
calculus. Some argue that too few students master even algebra. The use of
calculators became common in United States math instruction in the 1980s and 1990s. Critics have argued that calculator work, when not accompanied by a strong emphasis on the importance of showing work, allows students to get the answers to many problems without understanding the math involved. However, others such as
Conrad Wolfram argue for a more radical use of
computer-based math in a complete departure from traditional math. Mathematics educators, such as
Alan Schoenfeld, question whether traditional mathematics actually teach mathematics as understood by professional mathematicians and other experts. Instead, Schoenfeld implies, students come to perceive mathematics as a list of disconnected rules that must be memorized and parroted. Indeed, research suggests that certain approaches to traditional mathematics instruction impresses upon students an image of mathematics as closed to imagination and discovery, an image in clear opposition to how experts view the field. ==Traditional mathematics texts==
