Distance learning has provided an excellent platform for students in geographically remote locations while enabling them to learn at their own pace and convenience. A number of technologies are currently being utilized to conceptualize, design, enhance and foster distance learning. Teleconferences, electronic field trips, podcasts, webinars, video…

In this paper, I use a holographic metaphor to explain the identification of overlapping sign language communities in Panama. By visualizing Panama's complex signing communities as emitting community "hotspots" through social drama on multiple stages, I employ ethnographic methods to explore overlapping contours of Panama's sign language…

This thesis explores the use of Augmented Reality (AR) in two challenging scenarios -- autism therapy, and network-constrained, remote collaboration. In the first half of this thesis, we highlight the design and implementation of CustomAR and Augmented Playgrounds -- two applications that leverage the visualization and contextual abilities of AR…

Virtual reality, although it is in the real world, is a three-dimensional simulation model that brings users to a different environment with computer-generated graphics, video and audio, and enables communication with the media. Virtual reality is the imitation of the physical structure from a real world or an imaginary world in a…

According to the most recent data from the federal Chemical Safety and Hazard Investigation Board, between 2001 and 2011, more than 120 university laboratory accidents have caused injuries (including one death) and millions of dollars in damages. Laboratory-safety lessons normally comprise lecture slides alongside occasional movies and tours of…

This paper reports on how participation in a secondary school musical production, within a life skills education programme, may contribute curricularly and pedagogically towards equipping learners for meaningful, successful living in a rapidly transforming society. Using the life skills curriculum for the subject Life Orientation, and employing…

E-learning is a byproduct of instructional design. Thus online learning designers, in their approaches are expected to be familiar with the epistemological underpinnings of several theories and their consequences on the process of instruction. In the same vein constructivism holds assumptions, that learning is an active process whereby the learner…

Hologram recording and holographic interferometry are intrinsically sensitive to phase changes, and therefore both are easily perturbed by minuscule optical path perturbations. It is therefore very convenient to bank on holographic setups with a reduced number of optical components. Here we present a compact off-axis holographic setup that…

A holographic process is presented where the object is made of the real image produced by a two-mirror system. Single-step reflection hologram recording is achieved. Details of the process are given, optics concepts are outlined and demonstrative results are presented. (Contains 6 figures and 2 footnotes.)

Describes an experiment for recording holograms using a minimum of costly apparatus. Includes a description of apparatus and materials, the procedure for recording the hologram, the processing of the hologram, and the reconstruction of the image. (GS)

Discusses the principles behind holograms: the design and procedure to make either a reflection hologram or a transmission hologram, developing the hologram, safety precautions, and classroom applications. (JRH)

Outlines what a hologram is, the main types of holography, and how a simple system producing a white light reflection hologram can be set up in a school physics laboratory. Discusses the basic optics of the hologram and procedures and materials for making holograms in school. (YP)

Described is the phasor method of superposition of waves. The intensity pattern from a system of microwave sources is calculated point by point on a plane corresponding to a film emulsion, and then printed and directly converted to a hologram for 3-cm microwaves. Calculations, construction, and viewing of holograms are included. (Author/DS)

Discusses holography, a process by which a three-dimensional image of an object can be completely recorded on a photographic film or plate. Introduces hologram theory with a view to presenting it to senior high school students, and explains how the apparently very great experimental difficulties can be overcome. (JR)

Describes the design and fabrication of a classroom hologram and activities utilizing the hologram to teach the concepts of real and virtual images to high school and introductory college students. Contrasts this method with three other approaches to teach about images. (MDH)
