We have small journals that we photocopied ourselves and stapled together. Clip art on the cover; one page per month. We call them Faith Journals.
My thinking is that even if they don't get done EVERY week there is still a place for them. Sometimes I am on the ball enough to have questions made up for the teacher's to pose to the students for journal time and sometimes not.
We started using journals in our first year for Rotation and I really thought before starting out that in theory journals were a great idea. After our first year, I still believed they were a good idea!
Journaling cause the child to reflect back on the lesson and bring something out of themselves about it that they record either in words or pictures.
