This article reports a subset of findings from a larger study centered on designing a series of six digital learning objects to help Grade 5 (age 10-12) students begin to consider the nature of models (understood as the physical or mental representation of objects, phenomena, or processes), the particle nature of matter, and the behavior of…

From 2004-2007, the University of Memphis carried out the NSF-funded Tri-P-LETS (Three P Learning Environment for Teachers and Students) project to improve local high-school computer science curricula. The project reached a total of 58 classrooms in eleven high schools emphasizing problem solving skills, programming concepts as opposed to syntax,…

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…

This paper reports on findings from a five-teacher, exploratory case study, critically observing their implementation of a technology-intensive, augmented reality (AR) mathematics curriculum unit, along with its paper-based control. The unit itself was intended to promote multiple proportional-reasoning strategies with urban, public, middle school…

Science educators and school administrators are reexamining the educational value of animal dissection in the nation's schools and are focusing on simulation as an instructional alternative. One implication of the debate is that simulations can lead to equivalent learning to hands-on dissection. The second implication is whether dissection is…

Appropriate educational technologies have the potential to make physics' concepts more accessible through visualization, modeling and multiple representations. Students are engaged in more powerful scientific activities and they are able to perform investigations that would not be possible without the use of technology. This paper presents…

The goal of this project was to help science teachers shift to a more inquiry-based teaching style by supplying learning tools that support a more student-centered approach. The project employed PSI (Personal Study Instrument) Sim Modules, a simulation-based electronic learning environment designed to address misconceptions in middle school…

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…

The dual purpose of this article is to provide a synthesis of the findings related to the use of computer simulations in physics education and to present implications for teachers and researchers in science education. We try to establish a conceptual framework for the utilization of computer simulations as a tool for learning and instruction in…

Both virtual and physical manipulatives are reported as effective learning tools when used with different groups of students in a variety of contexts to learn mathematical content. The use of multiple representations and the flexibility to translate among those representational forms facilitates students' learning and has the potential to deepen…

This article contains a description of the organization and method of use of an active learning environment named MODeLeR, (Multimedia Object Design Learning Resource), a tool designed to facilitate the learning of concepts pertaining to object modeling with the Unified Modeling Language (UML). MODeLeR was created to provide an authentic,…

Presents the listing for a TRS-80 Model III program which illustrates the first law of robotics (all robots must be programed so that none of their actions will be harmful to man). Also discusses the rational for and development of the program. (JN)

Presents the LOGO computer language as a source to experience and investigate scientific laws. Discusses aspects and uses of LOGO. Lists two LOGO programs, one to simulate a gravitational field and the other projectile motion. (MVL)

Describes a simulation-oriented computer microworld named CHANCE used to overcome the limitations of physical materials for experiments in teaching and learning introductory probability. Results of a teaching experiment conducted with four middle school and high school students are discussed. (15 references) (LZ)
