O Slide that are not enclosed in glass cover can accumulate dust and fingerprints.

O Careless storage or handling can easily lead to permanent damaged.

Liquid Crystal Display Projector (LCD)

O Usually contain separated LCD glass panel, one each for red, green, and blue components of image signal being fed into the projector.

O Using a digital or analog signalO VCRO DVDO Computer

AdvantageOAllows for quick and easy set-upOMake presentation more polish

and professional productOEnhance learning experience.

Shows “live” presentationOCaptivate the attention of the

sequence as photographic equipment is continually refined and simplified

Disadvantage/Limitation

OIt is no longer available and are already outmodes, school have dispose of a replace them w/ computer and other equipment

Opaque ProjectorOIt is enlarge and display

non transparent material on screen. It allows on the spot projection of readily classroom material

AdvantageOIt enable to display visual of magazine, small specimen

OIt accept a wide range picture size

Disadvantage/Limitation

ODisc recordingOMagnetic tape recording

Disc RecordingO Come in various size, spin, and

speedO 78 rpm(revolution per minute) rotate

at speedO 33 1/3 rpm disc ( 10 – 15 minutes of

info. Each side microgroove)

OTeacher used listening equipment hardware and software to best advantage for students skill

OCompact disc (CD)OMP3 (MPEG Audio player 3)OEducational Radio Broadcasting

recording may be in reel-to-reel and cassette disc type

OIt has 6.24mm wideOC-60,C-90,C-120

minutes recoding time of cassette tape

VISUAL TECHNOLOGIES

OEducational Television (ETV) as a system of broadcasting w/c covert light patter into electric impulse and electric impulse into light pattern as transmitted by wire or radio to receivers
