Most links in the table below take you to a Pros Write post made up of (a) a brief motivation for learning about a writing topic, (b) a video tutorial, (c) the sample document used in the tutorial, and (d) related research. To hear the teaching philosophy behind these tutorials, check out Lectures in a writing class. Oh my! and Amateurs need explicit knowledge — not platitudes.
The video tutorials are between 9 and 15 minutes long. I hope to find time to update/shorten them in the future. Their content expands on the chapters in the 3rd and 4th editions of my co-authored workbook, Revising Professional Writing in Science and Technology, Business, and the Social Sciences (RPW).
