3.1. data input

3.1.1. keyboard

3.1.1.1. benefits: 
- relatively universal means of data entry and computer interaction - necessary competency for students (Lever-Duffy & McDonald, 2011, p. 117) challenges: - limited accessibility for some populations application to learning: - allows human interaction with the computer, the internet, and software - teacher may substitute touch screens or voice detection to facilitate access

3.2. pointing devices

3.2.1. multi-button mouse

3.2.1.1. benefits:
 - relatively universal - allows a variety of interactions including linking and drawing challenges: - limited accessibility for some populations - easily removed from workstation application to learning: - allows human interaction with the computer, the internet, and software. - useful for drawing and enhancing content

3.2.2. laptop trackpad

3.2.2.1. benefits:
 - adds portability to computing - computer is not constrained to a desk - allows a variety of interactions including linking and drawing challenges: - limited accessibility for some populations application to learning: - allows human interaction with the computer, the internet, and software. - useful for drawing and enhancing content.

3.3. media

3.3.1. scanner

3.3.1.1. benefits: - allow digitizing of hard copy material challenges: - file size must be considered application to learning: - allows for digital access to hard copy material for use and enhancement

3.4. digital camera

3.4.1. benefits: - quick turnover time from image capture to publication - create digital content for use and enhancement challenges:
 - file size must be considered - size of final content needs to be considered - require care in use and storage application to learning: - allows multiple means of representation, engagement, and expression

3.5. microphone

3.5.1. benefits: - allows the recording of digital sound files for use and enhancement challenges: - file size must be considered application to learning: - enhance representation, engagement and expression when creating multimedia presentations

4.1. hard copy

4.1.1. printer

4.1.1.1. benefits: - allows printing and hard copy distribution of digital content challenges: - supplies and maintenance are costly compared to digital distribution application to learning - material may be accessed without a computer - allows display of material in a variety of ways

4.2. soft copy

4.2.1. monitor

4.2.1.1. benefits: - relatively universal means of interacting with computers - allow visual interaction with the computer via pointing devices challenges: - limited accessibility for some populations application to learning: - display visual content in all communications: text, video, graphics, etc.

4.2.2. projector

4.2.2.1. benefits: - allows for group viewing of digital content & computer screen challenges: - expense, particularly when high quality and visibility are desired application to learning: - display visual content in all communications: text, video, graphics, etc.

4.3. media

4.3.1. audio

4.3.1.1. speakers

4.3.1.1.1. benefits: - allow listening to audio in multimedia content challenges: - expense, particularly when high quality in a group setting is required application to learning: allow for multiple channels of presentation, engagement and expression

4.3.1.2. headphones

4.3.1.2.1. benefits: - allow listening to audio in multimedia content challenges: - easily removed from station - may require adaptors application to learning: - allow for multiple channels of presentation, engagement and expression - allow individuals to access audio without interfering with other learners
