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…

The article studies the holographic projection technology in an innovative music classroom during full-time education. The study addresses the influence of this technology on the effectiveness and efficiency of learning, as well as on the perception and memorisation of educational material by students. It describes an innovative music classroom…

In line with the fast advance seen in technology, the use of technological resources in education has come to play an important role in terms of drawing students' attention to the subjects studied in the classroom so that success increases and the knowledge is better internalized. This study was carried out to determine the attitudes of the…

Techniques for training staff in the use and maintenance of microfilm readers and communicating effectively with users. (Author)

The construction of a device is described which converts an ordinary horizontal-stage overhead projector into a vertical-stage projector. The parts cost $60 and seven hours of labor are required. (BB)

Although there has been previous research concerned with image size, brightness, and contrast in projection standards, the work has lacked careful conceptualization. In this study, size was measured in terms of the visual angle subtended by the material, brightness was stated in foot-lamberts, and contrast was defined as the ratio of the…

A trade show of educational hardware and software was the highlight of a week-long convention, which also offered a full program of education and training sessions. (RK)

Describes modifying a slide projector into a macro-projector to show objects too small for an overhead projector and too big for a micro-projector. Describes a box to produce multiple images of objects. (BR)

A CATALOG HAS BEEN PREPARED TO HELP TEACHERS SELECT AUDIOVISUAL MATERIALS WHICH MIGHT BE HELPFUL IN ELEMENTARY CLASSROOMS. INCLUDED ARE FILMSTRIPS, SLIDES, RECORDS, STUDY PRINTS, FILMS, TAPE RECORDINGS, AND SCIENCE EQUIPMENT. TEACHERS ARE REMINDED THAT THEY ARE NOT LIMITED TO USE OF THE SUGGESTED MATERIALS. APPROPRIATE GRADE LEVELS HAVE BEEN…

The overhead projector is an excellent tool for teachers at both the high school and college level. Teachers often use it to display class notes as they monitor students' actions and reactions to the concepts being presented and discussed, to display diagrams and figures too complex to draw on the chalkboard, and more recently to display computer…
