Graphing calculators facilitate learners' ability to build cognitive links between mathematical representations by providing quick access to multiple representations. This exploratory study investigated the effects of technology-enhanced instruction on student achievement, perceptions of technology use during instruction, problem-solving success,…

This paper reports the results of an investigation on the effect of cooperative learning on academic achievement of physics course. Cooperative learning was employed to experimental group and conventional teaching method was used for control group. Sampling of the study consists of 15-16 years old 220 students at high school in Iran. The progress…

This article reports the findings of an experimental study involving 36 primary school students (16 girls, 20 boys, Mean age = 9.5 years, age range: 8-10 years) in geometrical understanding of 2D and 3D objects. Students were assigned into two experimental groups and one control group based on a stratified random sampling procedure. The first…

What do experienced teachers have to say about integrating modern educational games into their classroom? This paper addresses this question by exploring the discourse of teachers who were provided professional development, technical support, access to a modern educational game, and flexibility in deciding how to integrate the game in their…

Calculators are a controversial, yet widely used tool in mathematics education for all students and especially for students with disabilities. However, little research has explored calculators and students with disabilities. This paper explored the influence of calculator type (four-function and graphing) on the mathematical performance of…

In late October 1967, the USS Scorpion was lost at sea, somewhere between the Azores and Norfolk Virginia. Dr. Craven of the U.S. Navy's Special Projects Division is credited with using Bayesian Search Theory to locate the submarine. Bayesian Search Theory is a straightforward and interesting application of Bayes' theorem which involves searching…

This article reports findings from a study examining how altered readability levels affected struggling readers' (N = 288) comprehension of scientific concepts and vocabulary. Specifically, the researchers were interested in learning what effect altered readability levels have when low ability readers participate in a technology-based science…

Educational robotics activities are gaining in popularity. Though some research data suggest that educational robotics can be an effective approach in teaching mathematics, science, and engineering, research is needed to generate the best practices and strategies for designing these learning environments. Existing robotics activities typically do…

The goal of the X-Tech project was to enhance preservice teachers' perceptions of their preparedness to teach with technology. Results indicated that practically-oriented methods that meet a variety of technology related needs are viable for attaining such a goal. Further, it is particularly beneficial to have teachers use a variety of resources…

Pre-calculus concepts such as working with functions and solving equations are essential for students to explore limits, rates of change, and integrals. Yet many students have a weak understanding of these key concepts which impedes performance in their first year university Calculus course. A series of online learning objects was developed to…

The use of Computer Algebra Systems (CAS) is becoming increasingly important and widespread in mathematics research and teaching. In this paper, I will report on a questionnaire study enquiring about mathematicians' use of CAS in mathematics teaching in three countries; the United States, the United Kingdom, and Hungary. Based on the responses…

The projects Xmath (Bringslid and Canessa, 2002) and dMath (Bringslid, de la Villa and Rodriguez, 2007) were supported by the European Commission in the so called Minerva Action (Xmath) and The Leonardo da Vinci programme (dMath). The Xmath eBook (Bringslid, 2006) includes algorithms into a wide range of undergraduate mathematical issues embedded…

The culture of the young may, in fact, be a harbinger enticing us to follow a pathway from which will emerge the re-conceptualized educational practices of this new century. The culture of those older will, no doubt, strive to maintain the more golden aspects of their now historical learning experiences. One of the tasks of all educators, but…

This paper describes a study aimed to identify most common impediments related to the introduction of an open-source mathematical software package GeoGebra. We report on the analysis of data collected during a three-week professional development programme organised for middle and high school teachers in Florida. The study identified challenges…

In this paper we report on the sustained research and development work at the AMSTEL Institute of the University of Amsterdam to improve mathematics and science education at primary and secondary school level, which has lead amongst other things to the development of the integrated computer working environment Coach 6. This environment consists of…
