Not only is Technical Communication Today firmly rooted in core rhetorical principles, but the text also presents computers as thinking tools that powerfully influence how we develop, produce, design, and deliver technical documents and presentations.    Technical Communication Today  speaks to today's students and how they expect to learn information. Instructional narrative is “chunked,” so that readable portions of text are combined with graphics. This presentation facilitate learning, and models the way today’s technical documents should be designed. Additionally, the chunked presentation integrates an awareness of how documents are read—often “raided” by readers seeking the information they need.  By mirroring these processes in its content and structure, Technical Communication Today offers readers a higher level of accessibility.
