Instructors that have adopted journalizing as a regular habit and routine find that it helps them a couple of ways. The thing is the teaching journal can be whatever format and content the instuctor chooses to include. But over time, reflecting personal comments, observations, needs, wants, hopes, etc. can be invaluable as an introspective assessment of growth and improvement as an instructor. Of course, this can only occur by journalizing, and observing notations made over months and years.
