In the modern day classroom, how often do we notice the gorilla moving around our room? The term teacher "withitness" refers to a teacher's ability to be aware of everything that is going on in their classroom, both visual and non-visual, verbal and non-verbal. Jacob Kounin first used the term in reference to his work on teacher group management skills. Students have coined the saying, "my teacher has eyes in the back of their head" to refer to this often innate teaching ability. It is believed that the more "withit" we are as a teacher the more effective we are at maintaining a positive classroom climate conducive to learning.
Why is this the case? It is my belief, that teachers, who are aware of everything happening around them can keep students on task and involved, are fully engaged in the learning of the children; they rarely take a moment to themselves during a lesson. These committed educators are constantly moving around the room, coaching, facilitating, scanning, probing, counseling and collaborating with students. Furthermore, when the students see that these teachers are immersed in their learning, they believe these teachers care and thus they care too!

I believe that 21st century learning can give students the opportunity to engage in learning opportunities that were not possible a few years ago, but not at the expense of teacher engagement. If we start to foster disengaging habits, like sitting at our desk for long periods of time, we are going to miss the gorilla in the room!
