As you reflect every Saturday after a session, you should always include the following:
- Goals for the day.
- Reflections/Assessments of those Goals.
- Problems that arose with lesson, students, lab, etc.
- What went really well -- better than you thought -- with response from students, lesson, lab, something new that you learned, etc.
- Solutions to any problems future, past, present... also, suggestions or "warnings" for future teachers.
- Recommended: some sort of image to represent the reflection for the day.

Hopefully using this list, reflections will be easier to write, more useful, and maybe even more fun!
