The 3D stereoscopic technique consists in providing the illusional perception of depth of a given object using two different images mimicking how the right and left eyes capture the object. Both images are slightly different and when overlapped gives a three-dimensional (3D) experience. Considering the limitations for establishing surgical…

The overhead projector is perhaps passing out of use, but it is still a useful device with which to do lecture demonstrations. In my early years at Kenyon I was teaching the pre-med course, and found that the overhead projector was an ideal platform for showing the phenomena of polarized light. This note is a discussion of how I learned to use the…

Objective: Crack cocaine use has increased rapidly throughout Mexico, along with rising HIV and hepatitis C virus (HCV) infections among vulnerable groups. The Tirando Esquina: Interviniendo Muros de Salud (TE:IMS) project uses projection-mapping technology and is the first of its kind to reach and provide health education at an individual and…

As I approach my 70th year in physics, let me tell my younger colleagues about my adventures with computation. When I was 14, my father gave me a slide rule because I appeared to be headed toward a career in physics. Since then, I have had experience with many other calculating devices.

The purpose of this article is to provide a brief overview of the history of projection in education, discuss potential benefits to using projection technology, and finally share ideas for the use of projection throughout typical lesson content (e.g., introductory, skill, fitness and game activities) for Physical Education programs. This is also…

An "active learning" classroom design recognizes the importance of students becoming engaged in their own learning. Using a mixed-methods approach, this study compared student-reported data (n = 219) and used the "community of inquiry" framework to evaluate the impact of environmental features on students' experience. Students…

Additive colors are interesting to young students. In this paper, we show a convenient and straightforward method to demonstrate this phenomenon by projector. It produces defocus blur and reduces imaging quality for color mixing. We believe this demonstration experiment can be performed in most classrooms.

This study aimed to evaluate learning outcomes of drawing orthographic projections between two groups of students: one group that learnt orthographic projections via audio-visual media and the other group through written material. An experimental design was used to determine the percentage increase in learning outcomes of both methods with…

This research presents an investigation on the utilization of Science, Technology, Engineering, and Mathematics (STEM) with Project-Based Learning as experiment class treatment and project-based learning as control class treatment to investigate students' critical thinking in optical instruments lessons, with a particular focus on the development…

In the late nineteenth and early twentieth centuries, at a time when administrations in various countries set up new school systems or considered reforming existing ones, world exhibitions offered the ideal opportunity for the transnational exchange of knowledge and ideas. This article demonstrates both the impact of ideological views and…

The aim of the study is to bring a critical perspective to the use of projection and copy technologies, which have become widespread and degenerate by developing technology, in the art of painting. The data were evaluated by methods such as literature review, sample analysis, observation and experience. Projection technologies and the history of…

For schools to successfully deliver the computer studies curriculum, they should have, among other things, qualified teachers and computer laboratories. This study investigated the availability of qualified computer studies teachers and computer laboratories in public secondary schools in Lusaka City, Zambia. A mixed-methods approach was employed…

In the early 1880s, Belgian educators were confronted for the first time with calls for the use of the optical lantern in schools. Around the same time, new pedagogical theories gained ground, which argued in favour of visually aided, more experiential forms of teaching. By investigating the pedagogical discourse on the introduction and use of…

This study examined the information and communication technology (ICT) skills relevant for effective learning possessed by undergraduate students. The study made use of descriptive survey research design. The study participants were 320 undergraduate students of university of Nigeria. The instrument used for data collection was "Relevant ICT…

A low-cost solar simulator using a LCD projector as a light source has been developed and tested successfully. The prepared simulator has an illumination spectral at the visible light region and is controllable using a computer. The prepared simulator with controllable spectral filter was used to utilize the current-voltage (I-V) measurement for…
