In order to understand the realistic use and impact of ICT on physics teaching in Ireland, a survey was used to gather information on teacher attitudes, confidence and concerns. Practical problems in the regular use of ICT affect some more than others. Factors such as availability of equipment and time to learn new skills (and interest in those…

The development of both the materials for an intermediate-level hybrid German writing course and the software in a virtual learning environment for the course may be viewed as activity systems. Viewing the individual components of each system as interrelated enables us to conceptualize the complexities of the development process, which goes well…

Protein structures are hard to represent on paper. They are large, complex, and three-dimensional (3D)--four-dimensional if conformational changes count! Unlike most of their substrates, which can easily be drawn out in full chemical formula, drawing every atom in a protein would usually be a mess. Simplifications like showing only the surface of…

The need, use, benefit and potential of e-portfolios have been analysed and discussed by a substantial body of researchers in the education community. However, the development and implementation approaches of e-portfolios to date have faced with various challenges and limitations. This paper presents a new approach of an e-portfolio system design…

This article presents a web-based tool designed to compute certified equations and graphs of geometric loci specified using standard Dynamic Geometry Systems (DGS). Complementing the graphing abilities of the considered DGS, the equations of the loci produced by the application are remotely computed using symbolic algebraic techniques from the…

The use of difference and differential equations in the modelling is a topic usually studied by advanced students in mathematics. However difference and differential equations appear in the school curriculum in many direct or hidden ways. Difference equations first enter in the curriculum when studying arithmetic sequences. Moreover Newtonian…

Numerous institutions of higher education have implemented a learning management system (LMS) or are considering doing so. This web-based software package provides self-service and quick (often personalized) access to content in a dynamic environment. Learning management systems support administrative, reporting, and documentation activities. LMSs…

This paper describes an experiment performed by the fourth year chemical engineering students in the process control laboratory at the University of Waterloo. The objective of this experiment is to test the capabilities of a constrained Model Predictive Controller (MPC) to control the operation of a Double Pipe Heat Exchanger (DPHE) in real time.…

Public libraries are redefining their roles in order to stay relevant to the needs of the communities they serve. Today, libraries are places where reading meets hands-on learning and where quietness coexists with voices and music. The latest advances in technology for children and teens, specifically, robotics sets and media-rich software, are…

A freely available, easy-to-use Excel spreadsheet for performing linear least-squares fits for (x, y) data with errors in both coordinates is described. (Contains 1 table and 1 figure.)

The release of Apple's iPad was met with great enthusiasm by educators and schools. Yet, if this new technology is retrofitted to traditional teaching activities its full potential will go unrealized. The presence of iPads alone will not generate transformative educational experiences in the social studies; however, the appropriation of the device…

Students' collaboration while learning could provide better learning environments. Collaboration assumes social interactions which occur in student groups. Social theories emphasize positive influence of such interactions on learning. In order to create an appropriate learning environment that enables social interactions, it is important to…

The design of the drive system for an automatic machine and its correct sizing is a very important competence for an electrical or mechatronic engineer. This requires knowledge that crosses the fields of electrical engineering, electronics and mechanics, as well as the skill to choose commercial components based upon their technical documentation.…

Faculties at all levels of education continue to ask, "How does technology fit into my teaching?" How can I teach my students to become technologically literate?" For some, the answers seem quite simple. Technology should be integrated into as many levels of the curriculum as possible. If we aspire to prepare students for the…

Exploring the Solar System in the elementary school curriculum has traditionally involved activities, such as building scale models, to help students visualize the vastness of space and the relative size of the planets and their orbits. Today, numerous websites provide a wealth of information about the sun and the planets, combining text, photos,…
