Pre-K CLASS Instructional Support Strategies

Lost in the Fog?

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.

This is how most teachers feel when it comes to Instructional Support. They’re aware that “Instructional Support Town” is out there, and that it is important to get there, but lost in a fog, uncertain at times about what it looks like there, how it sounds, and what to do to get there.

Never Fear, Help is Here!

Out of the fog you hear someone calling for you; the lantern on their boat shines through the fog, coming closer. As they approach, you call out to help them find you. Almost immediately, they are at your side offering to guide you to the dock – a trip they have taken many times.
Instructional Support Essentials for Teachers training is the answer to your questions about how to improve Instructional Support interactions. Like the friendly voice and the lantern in the fog, we’re here for you, ready to help you as you push forward for improved outcomes for children.
Build your knowledge of Instructional Support indicators and dimensions—and understand why they matter. Teachers who attend this training will: Build a lens to identify effective Instructional Support interactions, use CLASS language to describe effective Instructional Support interactions and explain why they are important to children’s development, watch real classroom videos illustrating effective interactions and apply this lens to their own teaching practices.
