Graphic Calculators and Micro-Straightness: Analysis of a Didactic Engineering
Peer reviewed Peer reviewed
Direct linkDirect link
Maschietto, Michela – International Journal of Computers for Mathematical Learning, 2008
This paper concerns the analysis of a didactic engineering, the aim of which is to introduce Calculus, at secondary-school level, through the relationship between global and local points of view. It was designed for a graphic-symbolic calculator environment and structured in accordance with a learning trajectory from identifying the graphical…

An Investigation of the Median-Median Method of Linear Regression
Peer reviewed Peer reviewed
Direct linkDirect link
Walters, Elizabeth J.; Morrell, Christopher H.; Auer, Richard E. – Journal of Statistics Education, 2006
Least squares regression is the most common method of fitting a straight line to a set of bivariate data. Another less known method that is available on Texas Instruments graphing calculators is median-median regression. This method is proposed as a simple method that may be used with middle and high school students to motivate the idea of fitting…

Learning through Information Communication Technology: Critical Perspectives
Peer reviewed Peer reviewed
Direct linkDirect link
Severinsen, G. – Australian Educational Computing, 2003
Technology in secondary schools has become of increasing interest as the power of the microchip has developed. For the students of Mathematics, computers and handheld graphic calculators need to be accessible to all. They are relevant to the needs of the students' courses and to support and develop their Mathematical learning (Smith, 1997).…
