Virtual math objects with pedagogical, mathematical, and cognitive fidelity
(Citations: 1)
The examination of mathematical and cognitive fidelity for math related websites has been studied by Web designers; yet teachers, and especially pre-service teachers, as users of technology in the classroom, also need to be familiar with pedagogical, mathematical, and cognitive fidelity. What is pedagogical, mathemat- ical, and cognitive fidelity; and, what makes a math website high in pedagogical, mathematical, and cogni- tive fidelity are discussed in this article. Evidence is shown that technology high in pedagogical, mathematical, and cognitive fidelity, when used in the classroom, improves student academic achievement.
