This is a form I use in my classroom for tracking students emotional states. When a student is noticeably distressed or has an outburst, I record what the cause was (if it is obvious or if they say what it was) and what they did in response. This covers most of my behavioral data collection needs.
I teach in an Emotionally Challenged classroom, and most of my students IEPs have behavior goals related to how they handle their feelings. However, I was at a loss for how to ethically and effectively track this. If I tried to set up a specific observation period, I'd run the risk of catching them on a bad week and judging their progress incorrectly. Or I could try to create situations which would put them under stress so I could see what they'd do, but that seemed unethical. I couldn't see any other way to collect this data meaningfully but to try to collect it all the time.
So I made this form. If I don't do comments, it takes a few seconds to record every incident. They are quick enough they can be done as an incident is happening, and simple enough that I can remember multiple simultaneous events and record them later.
This form has met almost all of my behavior-tracking needs. With it, I know if a student identifies what is bothering them, I know if they have responded appropriately, I know if they have acted violently, I know if they have eloped. There is some wiggle room in deciding whether someone is refusing or cooling off, but overall it's served me well.
I keep them in an envelope, with blanks in a pocket on the outside. At the end of every month, I total up the incidents for each student in my class. I bring the actual forms with me to IEP meetings so I can refer back to my comments and see the details of what was going on.
This could also be used for documenting the behavior of a problem student in a General Education class.
CAUTION: It is important to remember to write down when kids handle themselves well, not just when they flip out. This is the hard part. It took me 3 to 4 months to get good at it.
