In the following scenario, do we see reflective writing or reflective thinking?In an effort to match buddy reader from next 3rd grade, second grade...

I would say it is reflective thinking because the piece of
writing that the student is going to offer will reflect constructive criticism and
feedback. If it were reflective writing, it would seem as though the student is asked to
respond to a specific prompt, such as a reader's response, or as it is done in the case
of creative writing.

In both cases, of course, the student
is doing both thinking AND writing, but the student is judging both his own reading and
that of someone else's so more processes are taking place in their minds. They include:
critical thinking, inductive reasoning, comparing and contrasting, analyzing, and much
more.
