I used the text this semester in my PR Principles course. It's quite good, particularly the first half on general principles. The second half has chapters looking at individual specializations within PR, which was less helpful to my teaching. (Students don't really have a specialized interest yet.) If I use it again, I'll assign pairs of students to pick one of those chapters and give a class presentation on each specialization, so everyone doesn't have to read everything.
This textbook delivers a clear and concise understanding about a variety of key topics that are essential for the PR student. The emphasis on socially responsible communication highlights the necessity for the PR professional to remain ever vigilant with ethical issues.
I used this textbook in Spring 2021 and I am using it again as I found it useful for my class.
