Do You Know Of Research Showing That Writing For An “Authentic Audience” Helps Students Feel Motivated?

I know that my students appear to be more motivated to write at their best when doing so for an “authentic audience” apart from me.

That’s one reason I have an extensive The Best Places Where Students Can Write For An “Authentic Audience” list.

I’d be interested in hearing if you have suggestions of recent research that actually documents an increase in student motivation and/or writing improvement when there is an “authentic audience” that’s going to see it?

Thanks in advance for your help!

Here are responses I’ve received:

Reader Marie suggests this excellent Writing Next report.
