Eric.ed.gov – Pre-Service Teachers’ Attitudes toward Graphing Calculators in Math and Science. Case Study 10

eric.ed.gov har udgivet: The need exists for methods courses to address the pedagogy issues of using graphing calculators. There needs to be a teacher candidate forum to examine their pedagogical perspectives on using graphing calculators in teaching, to explore when and how to use graphing calculators in the classroom, and to provide opportunities to practice teaching with graphing calculators. A recent study by Lyublinskaya, Donoghue and Zhou (2006) tracked the effects of such training on elementary and secondary pre-service teachers in methods classes for math and science. All students were divided into two groups. The first group consisted of undergraduate and graduate students preparing to teach secondary science and math, and who were enrolled in math and science methods courses. The second group consisted of undergraduate students preparing to teach… Continue Reading

tandfonline.com – Developing Knowledge for Teaching Graphing of Bivariate Categorical Data

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Due to the increased role of statistics in current curriculum standards, there is at present a call for attention to secondary teachers’ knowledge for teaching statistics in teacher education. This article reports the results of a study that answered this call by addressing mathematics teachers’ knowledge for teaching graphing of bivariate categorical data. Novel curriculum materials to develop such knowledge were written then implemented with mathematics teachers in courses at four post-secondary schools. Results showed that prior to use of the materials, teachers’ graphical competence was limited with teachers often utilizing frequencies when analyzing the data. Following use of the materials, they were more likely to correctly use relative frequencies in their analysis and expanded their knowledge of… Continue Reading

Uncheck the box to turn MathJax off. This feature requires Javascript. Click on a formula to zoom. ABSTRACT Student insight into algebraic formulas, including the ability to identify the structure of a formula and its components and to reason with and about formulas, is an issue in mathematics education. In this study, we investigated how 16- and 17-year-old pre-university students’ insight into algebraic formulas can be promoted through graphing formulas by hand. In an intervention of five 90-min lessons, 21 grade 11 students were taught to graph formulas by hand. The intervention’s design was based on… Continue Reading
