This study aims to describe a novel teaching mode that allows for direct instructor-student and student-student discussions of material balance concepts by means of active learning. The instructor explains the concepts during class time while using a remotely controlled laboratory system that is projected on a screen with real-time access to the…

Simulation as a tool for medical education has gained considerable importance in the past years. Various studies have shown that the mastering of basic skills happens best if taught in a realistic and workplace-based context. It is necessary that simulation itself takes place in the realistic background of a genuine clinical or in an accordingly…

This paper uses an Activity Theory framework to evaluate the use of a novel, multi-screen, non-linear presentation tool. The Thunder tool allows presenters to manipulate and annotate multiple digital slides and to concurrently display a selection of juxtaposed resources across a wall-sized projection area. Conventional, single screen presentation…

Instruction in hematopathology at Mayo Medical School has evolved from instructor-guided direct inspection under the light microscope (laboratory method), to photomicrographs of glass slides with classroom projection (projection method). These methods have not been compared directly to date. Forty-one second-year medical students participated in…

This study aims to explore potential answers to the question of how and why IWBs are used during mathematics classes organised by teachers in a primary school. Qualitative data was obtained from primary school teachers through the use of observation forms and semi-structured interviews. The results of this study indicate that despite some large…

Emerging Trends in Science Education in a Dynamic Academic Environment highlights the changes that have occurred in science education particularly in institutions of higher learning in southern Nigeria. Impelled by the fact that most Nigerian Universities and Colleges of Education still adhere to the practices and teaching methodologies of the…

The camera obscura (Latin for "darkened room") is the earliest optical device and goes back over 2500 years. The small pinhole or lens at the front of the room allows light to enter and this is then "projected" onto a screen inside the room. This differs from a camera, which projects its image onto light-sensitive material.…

This article considers the emergence and meaning of a particular kind of surveillance in classrooms: the one represented by the gaze of the teacher. Drawing on teaching manuals and other normative material published between the 1820s and the 1960s, it is argued that the optical regime of the classroom underwent a decisive change during the second…

This report, the 20th edition of "Technology Counts," examines how schools are tackling tech training for teachers, "passive" vs. "active" use of digital tools, and online learning needs. Contents include: (1) Tracking 20 Years of Change in Ed Tech (Kevin C. Bushweller); (2) Poor Students Face Digital Divide in How…

A lens based on liquid in the confined volume of a volumetric flask was presented as a potential projector to observe microscopic floating organisms or materials. In this experiment, a mosquito larva from a natural pond was selected as a demonstration sample. By shining a light beam from a laser pointer of any visible wavelength through the…

Many years ago I was running the standard laboratory experiment on thin lens optics. The source was the usual self illuminated object mounted on an optical bench, and a converging lens formed a real image on a screen. One of the students sitting near one wall of the darkened lab was having some trouble with the idea of image formation. Her face…

It may be too soon for students to be showing up for class with popcorn and gummy bears, but technology similar to that behind the 3D blockbuster movie "Avatar" is slowly finding its way into college classrooms. 3D classroom projectors are taking students on fantastic voyages inside the human body, to the ruins of ancient Greece--even to faraway…

This research aims to answer the question, "How has the use of computer technology benefited the compulsory education system, focusing on Design and Technology?" In order to reply this question, it was necessary to focus on interactive whiteboards, e-portfolios and digital projectors as the main technology formats. An initial literature…

Various wave optics experiments can be carried out using an ordinary compact disc. The CD is suitable for use as a diffraction grating. For instance, a standard CD (700 MB) has 625 lines/mm. In this article, the authors describe two white-light diffraction demonstrations for a large audience, realizable using a CD (as reflection or transmission…

Recently, the use of stereoscopic three-dimensional (3-D) projection displays has increased in geoscience education. One concern in employing 3-D projection systems in large lecture halls, however, is that the 3-D effect is reported to diminish with increased angle and distance from the stereoscopic display. The goal of this work was to study that…
