Technical and Professional Writing

This course is designed to strengthen your understanding and mastery of language in the context of technical and professional communication. This involves exploring the concept of rhetoric and the various rhetorical options available for a given professional writing task. The truth is, you already know what rhetoric is in an instinctive way. Without knowing it, you use rhetoric in conversation and personal letters. The aim of the course, however, is to raise your rhetorical awareness to a more conscious and effective level when you sit down to write in the workplace.
