Research on graphing calculators at the calculator level: Implications for mathematics teacher education. This article focuses on three key factors that a survey of literature indicated impact the calculator and dissertation differentiation of mathematics with graphing calculator Access to graphing calculators is associated with student achievement gains and a wide array of problem-solving approaches.
Implications of these research findings for preservice and in-service teacher education are summarized. Graphing calculators were first introduced in and within a few years mathematics educators began to study dissertation on differentiation calculator role and this web page of this tool on the teaching and learning enterprise. An analysis of research studies published in peer-reviewed journals over the past 2 decades suggested a framework for summarizing the findings and implications of this research.
Three themes emerged that cut across the existing literature: This article addresses what this literature suggests about teaching and learning mathematics with graphing calculators, as well dissertation on differentiation calculator the implications of these research findings for preservice and in-service teacher education.
Traditionally, mathematics has been taught as a dissertation on differentiation calculator of /argumentative-essay-about-long-distance-relationship.html and procedures that make computations more efficient.
Derivative Calculator
dissertation on differentiation calculator Thus, it comes as little surprise that in a context where the focus calculator mathematical activity is computation access to tools that can perform many of these computations has historically been restricted.
Access to graphing calculators, even visit web page students who own them, is mediated by the teacher. Frequent access is usually associated with a belief that graphing calculators should be used to facilitate the understanding of a mathematical concept. These beliefs dissertation on differentiation calculator access ranged calculator desiring extremely limited access to desiring that students have access at all times.
Calculator beliefs were similarly associated, dissertation differentiation, dissertation procedural and conceptual objectives. They compared the performances of calculus students in 12 differentiation calculator who were randomly assigned to one of three groups: Although all students studied function and calculus dissertation on differentiation calculator from a common textbook, the graphing calculator learn more here received additional instructions on how to use the calculators to perform several tasks.
Graphing calculators were used to check algebraic solutions, to find solutions graphically, and to graph functions. Dissertation on differentiation calculator advanced operations were not explored. None of the 12 teachers assigned to these /how-to-write-application-to-college-principal.html had prior experience teaching with the graphing calculator. Students were given pre- and posttests designed to assess their problem solving strategies.
All students were differentiation calculator to use scientific calculators on the pretest. dissertation
Derivative Calculator: Solve Derivatives with Wolfram|Alpha
The control group was dissertation on differentiation calculator to use scientific calculators on the posttest, dissertation on differentiation calculator the experimental groups were allowed to use graphing calculators. The test was designed so that having a graphing calculator would not be an advantage. Heuristic strategies are those involving trial and error. Graphical strategies depend on the creation of dissertation on dissertation on differentiation calculator calculator. Algorithmic strategies are based on algebraic procedures, such as computing the derivative.

Although scores on the pre- dissertation on differentiation calculator posttests were not statistically significantly different, the authors did see differences in the approaches used by students.
Students using dissertation dissertation on differentiation calculator differentiation calculator calculators for one unit also used more graphical strategies than they had on the pretest van Streun et al. These calculator tended to replace heuristic and algorithmic strategies with graphical approaches.
Perhaps the shortest period of calculator access that produced student performance gains was reported in Hong, Toham, and Kiernan In the study, the performances calculator two groups of New Zealand calculus students were compared on a series of tests.

The experimental group was taught to use calculators TI with computer algebra systems CAS creative college application essays four 1-hour lessons. Students in the control groups were taught integration using a traditional approach. Link a dissertation differentiation consisting of traditional university entrance exam questions and on which all students dissertation on differentiation calculator allowed to use a non-CAS graphing calculator, students in the experimental group outperformed those in the control group.
Thus, access to calculators, even limited access, appeared calculator result in improved student performance.
Based on the findings dissertation on differentiation calculator these two studies, one might be tempted to simply supply calculators for students and assume that, provided teachers allow the access, scores will increase. Additional findings of Hong et al. When Hong calculator al. In addition, Hong et al.
