Technical writing is essential for all university students because if they can write efficiently and express themselves well and precisely, it will be easier for them to relay their ideas to others and hence find jobs easily, write well balanced reports, and more importantly perhaps know what they are writng and talking about. The more organozed one's speech or writing is, the more effective one will be. Non-native speakers of English, however, do not think oral and written communication is that important but once they use this book in an English class under the guidance of their teachers, they ABSOLUTELY CHANGE THEIR IDEAS I recommend this book to all teachers of English teaching English at freshman or sophomore level.
