We recently talked about why annual recertification is important (bottom line: it’s your yearly chance to test yourself against master-coded videos). But what about between recertifications? How do your observers ensure that they stay reliable throughout the year?
Calibration, like recertification, gives you a chance to check in with master-coded videos periodically to prevent drift.
Double-coding is when two certified observers code side by side and check their codes at the end of the day.
Debriefing is part of double-coding, but it gets its own bullet point because, done right, it can be a powerful tool for maintaining reliability. (Thank you, Amanda Williford, for a recent reminder of how to do this right!)
The best way to stay reliable is to code a lot and get a lot of input on your coding—either through feedback on master-coded videos, or feedback from your colleagues.
Do you have other methods you use?
Teachstone has been working hard for the past few months to provide you with case studies about various organizations who have transformed their classrooms through the use of the CLASS tool. We hope they help readers like you make informed decisions about some of the products we offer and introduce you to different ways you can impact teacher-student interactions.
Imagine you are steering a boat filled with precious cargo across the foggy surface of a lake. You need to deliver it safely to the other side so that it can be used to help the town. You can see some lights faintly through the fog, so you know the town is there, but you are really uncertain about finding the dock. You paddle forward tentatively, even a little fearfully.
