Effects of integrating the use of graphic calculators on mathematics performance from the cognitive load perspective.(Report)
Jun 01, 2008; ... ABSTRACT Cognitive load theory assumes that some learning environment impose greater demands than others, consequently impose a higher information processing load on limited cognitive resources in working memory. The theory holds that if an instructional strategy reduces ...
A unified approach for the order verification of numerical methods.(Report)
Jun 01, 2008; ... Abstract In this paper, we will present a unified numerical technique for the order verification of the error in numerical methods. Four examples are presented to illustrate the approach which include the order verification of the errors in Taylor polynomial approximation, the ...
Use of calculators in the mathematics classroom.(Report)
Jun 01, 2008; ... Abstract: A key variable in the use of calculators in the learning of mathematics is the teacher. In turn there are many factors that influence whether an individual teacher uses the calculator, and if they do then how they use it. This study reports on a ten-year longitudinal survey data ...
Generalizing 2D geometric properties to 3D with the aid of DGS.(Report)
Jun 01, 2008; ... Abstract In This paper we would show flow we could use computer programs in geometry researches. This paper contains the processes of generalizing the properties of 2D-geometry to that of 3D-geometry. In addition, we would show how we could generalize backward; we could ...
Interactive geometry and critical points.(Report)
Jun 01, 2008; ... Abstract Interactity geometry programs make it possible to explore critical points of functions of one and many variables, in courses at carious levels and in research projects. In this article, we show how easy-to-use Java applets illustrate critical point phenomena for ...
Finding signed areas and volumes inspired by technology.(Report)
Jun 01, 2008; ... Abstract We describe how we can find the singed area bounded by a parametric curse with respect to a slanted line, y = mx + b, in two dimensions. We extend this idea to the corresponding setting in three dimensions. These are special cases of Green's Theorem and the Divergence ...
Power series solutions of differential equations: programming and experimenting with technology.(Report)
Jun 01, 2008; ... Abstract. We build a procedure of progressive programming using a symbolic and graphic calculator that does not abandon in an abrupt way traditional pencil and paper techniques to solve differential equations with power series. Basic idea is the construction of one or several small pieces ...
Making connections: technology-based science experiments for teaching and learning mathematics.(Report)
Feb 01, 2008; ... Abstract Using science experiments in different courses of mathematics helps ground students' understanding of abstract mathematics concepts in real-world applications. Hands-on activities connect mathematics with science in a way that is accessible to teachers and students ...
Exploring the use of calculators in the Singapore's primary mathematics curriculum.(Report)
Feb 01, 2008; ... Abstract: The use of scientific calculators will be first allowed in Singapore Primary School Leaving Examination (PSLE) for all primary level mathematics subjects from the year 2009 onwards. All Primary 5 and 6 mathematics teachers will be expected to explore the use of calculators into ...
Mathematics, science and technology teachers working collaboratively with ICT.(Report)
Feb 01, 2008; ... Abstract Supported by the Partners in Learning Programme of Microsoft and the UK Teacher Development Agency (TDA), a group of five secondary schools from Hampshire are working together on developing collaborative approaches to teaching mathematics, science, technology and allied ...
Mathematics problems via popular culture.(Report)
Feb 01, 2008; ... Abstract: Creating problems that demonstrate the power and relevance of mathematics has always been a time consuming challenge. Here we demonstrate that the development of such problems can be efficiently aided with the use of video sharing websites, which require students to extract their ...
Enhancing prospective mathematics teachers' pedagogical knowledge of mathematical relations and equivalence relations.(Report)
Feb 01, 2008; ... Abstract: Fourth-year prospective mathematics teachers served as instructors and second-year future elementary school mathematics teachers participated as students in a unit on mathematical relations. Videotapes revealed that the fourth-year pre-service teachers were moderately successful ...
A complete classification of 2 x 2 linear iterative systems.(Report)
Feb 01, 2008; ... Abstract The study of 2 x 2 linear iterative systems is incorporated in many books on ordinary differential equations. As in the case of linear systems of differential equations, the classification of the equilibrium solution (0; 0) leads to an analysis of the eigenvalues and ...
Using Web-based multimedia applications to enhance mathematics instruction with Reed-Solomon codes.(Report)
Feb 01, 2008; ... Abstract In many introductory and upper level college mathematics courses, due to time constraints, students are often not exposed to many real-life applications of the material. As a result, students can fail to see the importance of the topics covered. However, the use of ...
Experiencing the multiple dimensions of mathematics with dynamic 3D geometry environments: illustration with Cabri 3D.(Report)
Feb 01, 2008; ... Abstract. The paper analyzes how 3D dynamic geometry environments may be used to foster the exploration of multiple dimensions of 3D geometry. The notion of dimension is twofold: it refers, one the one hand to the dimension of a geometrical object, on the other hand to the multiple types ...
Using dynamic geometry software to encourage 3D visualisation and modelling.(Report)
Feb 01, 2008; ... Abstract The Royal Society's working group report on the teaching and learning of geometry 11-19 [6] recommended both greater attention to work in 3D and more effective use of ICT. The development of the award-winning Cabri 3D software now makes both of these goals achievable ....
