The Commentary (teacher's notes and key) for the third edition of Academic Writing for Graduate Students has been revised and expanded to offer more guidance for teachers.

Among the many changes in the third edition of the student text are:

• newer, longer, and more authentic texts and examples
• greater discipline variety in texts (added texts from hard sciences and engineering)
• more in-depth treatment of research articles
• greater emphasis on vocabulary issues
• revised flow-of-ideas section
• additional tasks that require students to do their own research
• more corpus-informed content
