Graphing Calculators
Students begin the study of algebra. The numbers of those who do not understand are gradually reduced. They struggle at first, and eventually most begin to understand. Or do they? Studies would suggest otherwise. A great amount of research has been done in the past decade in an attempt to find out why Americans are consistently near the bottom on international comparative studies in mathematics. The minimum requirements of most universities establish a passing high school grade in one algebra, and one geometry course, as necessary for acceptance. Failure to meet these requirements excludes thousands each year from college entrance. A significantly large percentage of those who do pass, enter college with deficiencies in mathematics. Even upon completion of "college algebra" the struggle is not over. Calculus is the final summit that looms over the prospective college graduate. Demana (1995) says, "Though college students may have had as much as 2 1/2 years of algebra instruction, one of the most common complaints that we hear from our colleagues about college calculus students is that the algebra preparation for calculus is very poor. And it is our experience that this criticism is a valid one."
(2) calculators supply more tools for problem solving, and assist students weaker in algebraic skills by helping them "check their work" (3) students perceive problem solving differently when freed from the burden of numerical computation, allowed to concentrate on setting up the problem and analyzing the solution. Assessing this topic, the authors expressed their findings, "No significant difference in traditional algebraic skills were found between the experimental, and control groups. The 1998 study used stand-alone classroom only computers. Conceptual UnderstandingDo calculators improve conceptual understanding of algebraic ideas? There are specific challenges that require alternate research methods when evaluating someone's understanding. The graphing calculator is under critique. University students in all majors whether knowingly or ignorant, are required to make associations based on functions. Studies indicating an epidemic of American incompetence in mathematics are not a revelation, but rather a confirmation of past research. A 1997 study shows that teacher perception on the implementation of graphing calculators plays a vital role in determining its success (Ayers 1997). It is the cost of doing something differently. Under the first method, a student's ability to perform pencil and paper operations is under direct assessment. A detailed recommendation on curriculum, and policy is beyond the scope of this report. 05 level on the first three skills, and significance at the a = . The deficiencies noted at the undergraduate level, are explained (without formal research) by graphing calculators. In most areas of relevance, Americans were three to five times behind the other countries (Brenner, Herman, Hsiu-Zu Ho, Barbara, 1999). There is a need for curriculum and policy reform at Brigham Young University.
