Education Technologies: Input and Output Devices

1. An input device is a device that can be interfaced with a computer in which a user can enter data to be used by the computer .

2. (LCD or Data) Projector (display video or still imagery) Benefits: can 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.

3. Digital Camera (multiple uses in and out of the classroom, such as field trip documentation) Benefits: No need for film reloading or development; pictures are instant and may the BE Easily Transferred or copied to computer OTHER devices and storage. Drawbacks (challenges): Many different formats and costs for internal storage media.

4. The Bluetooth the Tablet The Whiteboard Interactive has (BE's Used in the PLACE of chalkboard Demonstrations and Equations) Benefits: the Designed to the BE . Drawbacks (challenges): Expensive and may need training to use.

5. Whiteboard of Electronic (may be used for classroom presentations) Benefits: Interactive has the substitute on chalkboard with capability of scanning and saving images displayed. Drawbacks (Challenges): May the BE prohibitively expensive for schools But lower technology.

7. Output Devices

8. Output is devce of An a device the connected to the computer with the which the computer may transmit timeout information or results to the user or another the connected device.

9. The Scanner (coverts pictures and text files is to digital is) Benefits: May the BE Used google translate and to the existing images and documents is is the most manipulative of BE and copied with software. Drawbacks (challenges): Not necessary for existing digital files but can be more useful when integrated into an all-in-one printer / copier / scanner machines.

10. Headphones (listening to computer software audio output) Benefits: A more private listening alternative to speakers. Drawbacks (challenges): Wiring may not be compatable and can create a disorganized and dangerous tangle.

10.1. Computer Speakers (listening to computer software audio output) Benefits: Necessary for audio output interface to user. Drawbacks (challenges): highly distracting for seperate computer users.
