Filmstrip
The filmstrip is a form of still image instructional multimedia, once commonly used by educators in primary and secondary schools (K-12), overtaken at the end of the 1980s by newer and increasingly lower-cost full-motion videocassettes and later on by DVDs. From the 1940s to 1980s, filmstrips provided an easy and inexpensive alternative to 16 mm educational films, requiring very little storage space and being very quick to rewind for the next use. Filmstrips were large and durable, and rarely needed splicing. They are still used in some areas. Technology A filmstrip is a spooled roll of 35 mm positive film with approximately thirty to fifty images arranged in sequential order. Like 16 mm film, a filmstrip was inserted vertically down in front of the projector aperture, rather than horizontally as in a slide projector. Therefore, the frame size is smaller than normal 35 mm film. Two image frames of a filmstrip take up the same amount of space as a single 35mm fra ...

Subaudible Tone
A subaudible tone is a tone that is used to trigger an automated event at a radio station. A subaudible tone is audible; however, it is usually at a low level that is not noticeable to the average listener at normal volumes. It is a form of in-band signaling. Overview These tones are included in the audible main portion of audio in the case of satellite; on tape, these often are filtered. Normally, subaudible tones are at one of the following frequencies: 25, 35, 50, 75 hertz (Hz), or combinations of those frequencies. Until computerized radio automation became inexpensive and common, 25 and 35 Hz were used either in the audio stream or, in the case of tape cartridges used in radio broadcasting (better known as "carts"), on a special track on the tape to indicate to a radio station's automation system that it was time to trigger another event. With the advent of computers and digital satellite, these tones are relegated to triggering commercial announcements and legal ...

35mm Movie Film
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips wide. The standard image exposure length on 35 mm for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th century and early 20th century, as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison, using 120 film stock supplied by George Eastman. ...

Coronet Films
Coronet Films (also known as Coronet Instructional Media Inc.) was a leading producer and distributor of many American documentary shorts shown in public schools, mostly in the 16mm format, from the 1940s through the 1980s (when the videocassette recorder replaced the motion picture projector as the key audio-visual aid). The company, whose library is owned and distributed by the Phoenix Learning Group, Inc., covered a wide range of subjects in zoology, science, geography, history and math, but is mostly remembered today for its post-World War II social-guidance films featuring topics such as dating, family life, courtesy and citizenship. Overview David A. Smart established the company with his brothers Alfred and John in 1934, but the first titles registered for copyright date from 1941 (beginning with ''Aptitudes and Occupations'').

Sunburst Media
A sunburst is a design or figure commonly used in architectural ornaments and design patterns and possibly pattern books. It consists of rays or "beams" radiating out from a central disk in the manner of sunbeams. Sometimes part of a sunburst, a semicircular or semi-elliptical shape, is used. Traditional sunburst motifs usually show the rays narrowing as they get further from the centre; from the later 19th century they often get wider, as in the Japanese Rising Sun Flag, which is more appropriate in optical terms. In architecture, the sunburst is often used in window designs, including fanlights and rose windows, as well as in decorative motifs. The sunburst motif is characteristic of Baroque church metalwork, especially monstrances and votive crowns, and Art Deco and Art Nouveau styles as well as church architecture. A sunburst is frequently used in emblems and military decorations. Sunbursts can appear in photographs when taking a picture of the Sun through the di ...

Gramophone Record
A phonograph record (also known as a gramophone record, especially in British English), or simply a record, is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Since the 1990s, records con ...

Compact Audio Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge and reel ...

Language Arts
Language arts (also known as English language arts or ELA) is the study and improvement of the arts of language. Traditionally, the primary divisions in language arts are literature and language, where language in this case refers to both linguistics, and specific languages. Language arts instruction typically consists of a combination of reading, writing (composition), speaking, and listening. In schools, language arts is taught alongside science, mathematics, and social studies. Reading Reading, by definition, is the ability and knowledge of a language that allows comprehension by grasping the meaning of written or printed characters, words, or sentences.
