Ocak, Mehmet Akif – EURASIA Journal of Mathematics, Science & Technology Education, 2008
This study investigates the role of graphing calculators in multiple representations for knowledge transfer and the omission of oversimplification in complex function graphs. The main aim is to examine whether graphing calculators were used efficiently to see different cases and multiple perspectives among complex function graphs, or whether…

Shield, Mal – Australian Mathematics Teacher, 2008
In this article, the author focuses on possible ways to develop the concepts of joint variation and function through the upper primary and lower secondary years of education. The examples demonstrate the building of a range of important mathematical ideas by modelling life-related situations using students' informal and intuitive knowledge. Over…

Huggins, Elisha – Physics Teacher, 2007
Much like a physical prism, which displays the frequency components of a light wave, Fourier analysis can be thought of as a mathematical prism that can tell us what harmonics or frequency components are contained in a recording of a sound wave. We wrote the MacScope II program so that the user could not only see a plot of the harmonic amplitudes…

Dewey, Brenda L.; Singletary, Ted J.; Kinzel, Margaret T. – School Science and Mathematics, 2009
This study examines graphing calculator technology availability, characteristics of teachers who use it, teacher attitudes, and how use reflects changes to algebra curriculum and instructional practices. Algebra I and Algebra II teachers in 75 high school and junior high/middle schools in a diverse region of a northwestern state were surveyed.…

Groth, Randall; Spickler, Donald; Bergner, Jennifer; Bardzell, Michael – Contemporary Issues in Technology and Teacher Education (CITE Journal), 2009
Because technological pedagogical content knowledge is becoming an increasingly important construct in the field of teacher education, there is a need for assessment mechanisms that capture teachers' development of this portion of the knowledge base for teaching. The paper describes a proposal drawing on qualitative data produced during lesson…

Buckner, Barbara Renee – ProQuest LLC, 2011
The purpose of this study was to determine the effect of TI-Nspire graphing calculator use on student achievement and on teacher behavior variables of planning, teaching, and assessing. This study investigated the teaching of functions by teachers using the TI-Nspire graphing calculator versus teachers using a non-graphing scientific calculator. …

Chamblee, Gregory E.; Slough, Scott W.; Wunsch, Gaye – Journal of Computers in Mathematics and Science Teaching, 2008
This article discusses the impact of a year long professional development on high school mathematics teachers' concerns regarding the implementation of graphing calculators in their classrooms. Teachers' concerns were assessed at the beginning and end of the yearlong professional development using the Concerns Based Adoption Model Stages of…

Steele, Marcee M. – Preventing School Failure, 2007
The most recent amendments to the Individuals With Disabilities Education Act (IDEA; 2004) and the regulations of the No Child Left Behind Act (2002) emphasize teaching general education curriculum to students with disabilities whenever possible. As a result, the majority of students with mild disabilities are educated in the general classroom,…

Berry, John S.; Graham, Ted; Honey, Suki; Headlam, Carrie – International Journal for Technology in Mathematics Education, 2007
Introducing any new initiative into teaching involves professional development and training. This paper investigates the reactions of three teachers to the introduction of graphics calculators into their department. Each teacher was followed through one academic year. They were interviewed formally on two occasions and also met informally with the…

Marchand, R. J.; McDevitt, T. J.; Bosse, Michael J.; Nandakumar, N. R. – PRIMUS, 2007
Many popular mathematical software products including Maple, Mathematica, Derive, Mathcad, Matlab, and some of the TI calculators produce incorrect graphs because they use complex arithmetic instead of "real" arithmetic. This article expounds on this issue, provides possible remedies for instructors to share with their students, and demonstrates…

Meagher, Michael; Ozgun-Koca, Asli; Edwards, Michael Todd – Contemporary Issues in Technology and Teacher Education (CITE Journal), 2011
This paper reports on a study of 22 preservice teachers enrolled in a first-semester mathematics teaching methods course. Course activities included participation in two separate field experiences in neighboring school districts. The methods class placed considerable emphasis on the use of advanced digital technologies in the teaching and learning…

Rivera, Ferdinand D. – Educational Studies in Mathematics, 2007
This paper provides an instrumental account of precalculus students' graphical process for solving polynomial inequalities. It is carried out in terms of the students' instrumental schemes as mediated by handheld graphing calculators and in cooperation with their classmates in a classroom setting. The ethnographic narrative relays an instrumental…

Sinn, Robb – Mathematics Teacher, 2007
An eighth grade algebra class used graphing calculators to simulate ecosystems. One simulation introduced mathematical chaos. The activities exposed the students to nonlinear patterns and modeling. The rate-of-change investigations related the ideas of intercept and slope to the changing equilibrium. The chaotic model intrigued them and was useful…
