Randy,
Another variation is post it notes and "red stars". For me, I formerly used a red pencil to mark a star in the margin of my notes when I noticed the lesson was taking longer, students had more difficulty than expected, or asked interesting questions that could be inserted into future lessons. Post it notes sort of achieved the same purpose. These reminders allowed me to scan through one or more lessons quite rapidly in orer to make journal notes.
