Mathematics in the Twenty-first Century
Polya, named the Father of Problem Solving, used a four-step heuristic in problem solving. He stressed that a problem is not finished until one has the opportunity to look back and extend the problem situation. Calculators and computers allow students to ask the "What if" questions and to explore. Technology has made alternative learning and teaching strategies available in the classroom for both the traditional and mathematically anxious student. It affords an opportunity for visualization of mathematics. For the teacher and the student, technology reduces the rote computational burden and allows both to focus on problems and concepts. The path to a solution once determined by the problem solver is cleared of many of the computational stumbling blocks.
