This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios.…

Over the past three years, the authors have conducted research in middle and high school classrooms in an effort to improve the effectiveness of robotics to teach science, technology, engineering, and mathematics (STEM) education--their focus has been on math. The authors have found that subtle changes in the design and setup of the lesson make a…

A basic setup for data acquisition and analysis from an oscillatory circuit is described, with focus on its application as either low-pass, high-pass, band-pass or band-reject frequency filter. A homemade board containing the "RLC" elements allows for the interchange of some of them, in particular, for the easy change of the "R" value, and this…

The Internet has changed how scholars perform their research. With more and more content available online that is fully searchable (often even for free), it is not surprising that students and others may turn there first before coming to the library. This study aims to identify the utility of three of the largest free access points to print…

The main purpose of the work is to present a successful implementation of CLIL method in Mathematics lessons in elementary schools. Nowadays at all types of schools (elementary schools, high schools and universities) all over the world every school subject tends to be taught in a foreign language. In 2003, a document called Action plan for…

This study designed and developed a web-based reading strategy training program and investigated students' use of its features and EFL teachers' and students' perceptions of the program. The recent proliferation of online reading materials has made information easily available to L2 readers; however, L2 readers' ability to deal with them requires…

The past few decades have witnessed the rapid development of information and communication technology around the world, as well as continuing efforts to introduce technology into K12 schools. To gauge the success of integrating technology into classrooms, how end users, including teachers and students, accept and use technology while overcoming a…

This article draws on research conducted at a tertiary institution in South Africa as part of the redesigning of an English for Educational Development (EED) course to include an e-learning online discussion component. The subject material used was based on HIV/AIDS topics that students had to debate within an online discussion forum. Framed by…

The use of Open Educational Resources (OERs) to support language teaching and learning in higher education has become standard practice in recent years. While OER initiatives have given considerable attention to teacher's engagement as well as the sharing of culture and the creation and uploading of OERs, there is little evidence about specific…

A research team conducted an evaluation of a laptop initiative in 18 North Carolina high schools through administrator, teacher, and student focus groups; teacher and student surveys; and classroom observations. The study aimed to provide information about the value of the laptop initiative in enhancing student learning. In addition, it intended…

This "Postcard" reports how the earthquake on Tuesday, 22 February 2011 in Christchurch, New Zealand, forced a visiting professor to transform his educational model in one week. It was the first week of the academic year 2011 for the University of Canterbury--and the author's first week in New Zealand. As a Visiting Erskine Fellow at the…

We report an action research project developed with ninth grade students of a public school in Bogotá, Colombia, and which focused on innovating English communication through writing blogs. The project took into account the implementation of a specific blog that proposes activities, suggestions, strategies and links, among other things, to…

This paper reports the results of a survey conducted to assess students' usage and perceptions of a finance lab. Finance labs differ from simple computer labs as they typically contain data boards, streaming market quotes, terminals and software that allow for real-time financial analyses. Despite the fact that such labs represent significant and…

For the first time in the history of collective action, the offline world has experienced a virtually organized and enacted union strike. While this was the first publicly noticed political action in a virtual world, others have been going on for several years now. As virtual worlds continue to grow in popularity, this type of protest of action…

This study explored the effects of Problem-Based Leaning (PBL) with web-anchored instruction in nanotechnology on the science conceptual understanding, the attitude towards science, and the perception of science in society of elementary students. A mixed-methods approach was used. Subjects (N=46) participated in the study for approximately two…
