What Happens When CAS Procedures Are Objectified?--The Case of "Solve" and "Desolve"
Peer reviewed Peer reviewed
Direct linkDirect link
Jankvist, Uffe Thomas; Misfeldt, Morten; Aguilar, Mario Sánchez – Educational Studies in Mathematics, 2019
Inspired by the entering of computer algebra systems (CAS) in the Danish upper secondary school mathematics program, this article addresses, from a theoretical stance, what may happen when traditional procedures are outsourced to CAS. Looking at the commands "solve" and "desolve," it is asked what happens when such CAS…

Davis, Jon D.; Fonger, Nicole L. – Educational Studies in Mathematics, 2015
The symbolic manipulation capabilities of computer algebra systems, which we refer to as CAS-S, are now becoming instantiated within secondary mathematics textbooks in the United States for the first time. While a number of research studies have examined how teachers use this technology in their classrooms, one of the most important factors in how…

Using Graphing Software to Teach about Algebraic Forms: A Study of Technology-Supported Practice in Secondary-School Mathematics
Peer reviewed Peer reviewed
Direct linkDirect link
Ruthven, Kenneth; Deaney, Rosemary; Hennessy, Sara – Educational Studies in Mathematics, 2009
From preliminary analysis of teacher-nominated examples of successful technology-supported practice in secondary-school mathematics, the use of graphing software to teach about algebraic forms was identified as being an important archetype. Employing evidence from lesson observation and teacher interview, such practice was investigated in greater…

Apprentissage dans un Environnement Informatique: Possibilite, Nature, Transfert des Acquis (Learning within an Information Environment: Possibilities, Native, and Transfer of Ideas).
Peer reviewed Peer reviewed
Dagher, Antoine – Educational Studies in Mathematics, 1996
Examines possibilities for learning offered by a piece of software, Fonctuse, likely to encourage the linking of algebraic and graphical representations of functions. Studied the influence of prior algebraic knowledge on the cognitive processes and constructions of knowledge at play in this environment. (Author/MKR)

Providing a Computer Based Framework for Algebraic Thinking.
Peer reviewed Peer reviewed
Sutherland, Rosamund – Educational Studies in Mathematics, 1989
Investigated are the developments of pupils' use and understanding of algebraic ideas within a LOGO programing context and a non-computational context. The research consists of a 3-year longitudinal case study of 4 pairs of pupils aged 11-16. LOGO experience enhanced the understanding of algebraic ideas. (Author/YP)

The Effect on Students' Attitudes of the Computer as a Teaching Aid.
Peer reviewed Peer reviewed
Ganguli, Aparna B. – Educational Studies in Mathematics, 1992
The effects on college students' (n=110) attitudes of using a microcomputer as a demonstration aid was investigated in an intermediate algebra class. Results suggest a significant treatment effect on students' attitude favoring the microcomputer treatment group. (16 references) (MDH)
