Doerr, Helen M.; Zangor, Roxana – Educational Studies in Mathematics, 2000
Describes how the meaning of a tool was constructed by students and their teacher, and how students used the tool to construct mathematical meaning out of particular tasks through a qualitative classroom-based study. Suggests that the nature of the mathematical tasks and the role, knowledge, and beliefs of the teacher influenced the emergence of…

Alexopoulos, John; Abraham, Paul – International Journal of Computer Algebra in Mathematics Education, 2001
Demonstrates a less utilized feature of the TI-92+: its natural and powerful programming language. Shows how to implement several linear algebra related algorithms including the Gram-Schmidt process, Least Squares Approximations, Wronskians, Cholesky Decompositions, and Generalized Linear Least Square Approximations with QR Decompositions.…

Connors, Mary Ann; Snook, Kathleen G. – International Journal of Computer Algebra in Mathematics Education, 2001
Investigates the impact of the TI-89 hand-held Computer Algebra System (CAS) on student achievement in a first year college core calculus course. Analyzes data from an experimental study conducted at the United States Military Academy at West Point from 1998-2000. Results indicate that the TI-89 hand-held CAS experimental group attained a higher…

Simonsen, Linda M.; Dick, Thomas P. – Journal of Computers in Mathematics and Science Teaching, 1997
Compiles teachers' impressions of the barriers and/or incentives associated with the use of graphing calculators on classroom dynamics, curriculum and evaluation, training, support, and overall attitude. Concludes that teachers' perceptions of the advantages appeared to be instructionally related, whereas perceptions of the disadvantages appeared…

Holliday, Berchie W.; Duff, Lauren R. – Mathematics Teacher, 2004
The students need not compute dependent values required in making line graphs but to teach the students the usage of graphing calculator to plot, calculating and graph linear equations, which are best suited to real world data. In this initial learning process, the teacher should give minimum support to the students in arriving at a solution as…

Kasturiarachi, A. Bathi – International Journal of Mathematical Education in Science and Technology, 2002
Using Newton's method as an intermediate step, we introduce an iterative method that approximates numerically the solution of f(x) = 0. The method is essentially a leap-frog Newton's method. The order of convergence of the proposed method at a simple root is cubic and the computational efficiency in general is less, but close to that of Newton's…
