The teacher sits in a large wooden rocking chair. One by one, she invites her third-graders to get up from their desks and take a place in front of her on the rug. “Thank you, Kiara,” she says, complimenting a scrawny child with long black hair for sitting criss-cross-style. As the other students take their places on the rug, the teacher sits on the edge of her chair. Her eyes move from left to right, watchful for misbehavior.
“Look at that teacher scan,” says Jim Lengel with an excited laugh. “It’s like radar.”
The students freeze as Lengel, a visiting professor at Hunter College School of Education, pauses the video he’s been watching them on. Ten of the third-graders are looking directly at the teacher, while two look off toward the camera.
