Education Technologies: Input and Output Devices

Input Devices

Output Devices

Electronic Whiteboard (may be used for classroom presentations) Benefits: Interactive chalkboard substitute with capability of scanning and saving images displayed (Lever-Duffy, & McDonald, 2011). Drawbacks (challenges): May be prohibitively expensive for schools but technology is developing to convert non-electronic whiteboards to electronic at lower prices.

Interactive Whiteboard Bluetooth Tablet (may be used in place of chalkboard demonstrations and equations) Benefits: Designed to be integrated with whiteboard for use throughout classroom (Lever-Duffy, & McDonald, 2011). Drawbacks (challenges): Expensive and may need training to use.

Digital Camera (multiple uses in- and outside of the classroom, such as field trip documentation) Benefits: No need for film reloading or development; pictures are instant and may easily be transferred or copied to other computer devices and storage (Lever-Duffy, & McDonald, 2011). Drawbacks (challenges): Many diverse formats and costs for internal storage media.

Scan Converter  (translates computer imagery for display on television)               Benefits:  Converts computer digital signals to analog for transmission to video recorder or television; an inexpensive option to many other video media (Lever-Duffy, & McDonald, 2011).                  Drawbacks (challenges):   Image resolution can degrade.

An output devce is a device connected to the computer with which the computer may transmit information or results to the user or another connected device (Lever-Duffy, & McDonald, 2011).

An input device is a device interfaced with a computer into which a user may enter data to be used by the computer (Lever-Duffy, & McDonald, 2011).

(LCD or Data) Projector (display video or still imagery) Benefits: may replace television monitor, overhead projector, and slide projector; interfaces with computer. Drawbacks (challenges): May require darkened room to view; May not work with whiteboards and require projection screen.

Computer Speakers (listening to computer software audio output) Benefits: Necessary for audio output interface to user (Lever-Duffy, & McDonald, 2011). Drawbacks (challenges): highly distracting for seperate computer users.

Headphones (listening to computer software audio output) Benefits: A more private listening alternative to speakers (Lever-Duffy, & McDonald, 2011). Drawbacks (challenges): Wiring may not be compatable and can create a disorganized and dangerous tangle.

Scanner (coverts pictures and text to digital files) Benefits: May be used to translate existing images and documents into digital files which may then be manipulated and copied with software (Lever-Duffy, & McDonald, 2011). Drawbacks (challenges): Not necessary for existing digital files but can be more useful when integrated into all-in-one printer/copier/scanner machines.
