Technical Communication in the Twenty-First Century (TCTC) will prepare students to be successful writers and readers of technical communication, regardless of their career path. This text features a wealth of interesting examples, applications, and cases that engage the student and demonstrate both effective and flawed communication. An emphasis is placed on analyzing why something worked or did not work as well as on how to produce the appropriate communication. TCTC's problem-solving approach asks students to think rhetorically about writing situations through detailed explanations and specific examples. The Problem-Solving Approach (PSA) provides students with a useful heuristic to guide them through the process of analyzing a variety of communication situations and solving workplace communication problems.
