I came across this highly recommended PD resource that you might find of value.
The Teaching Channel is a video showcase of inspiring and effective teaching practices in America’s schools. Videos range from 1-30+ minutes on topics from planning lessons to exit strategies. Search by grade-level and/or subject. You can even follow your favorite teachers. Or, sign up for an account and upload your own videos!
For an example, see “The Stoplight Method: An End-of-Lesson Assessment”
