Improving educators' abilities to recognize and respond to signals that indicate students are upset, confused, or disengaged is a powerful but often underused strategy for ensuring that all students are accessing rigorous learning. Research has shown that when adults respond to students' social and behavioral cues for help in a timely, proactive, and sensitive matter, students are more able to get back on track with important learning tasks at hand. Teachstone, a company using education technology to improve the ways teachers interact with students, has developed practical tools that can help teachers notice and respond more quickly and effectively to student academic and social-emotional cues. The tools are grounded in the Classroom Assessment Scoring System (CLASS), a framework underlying teacher professional learning models that grew out of research conducted at the University of Virginia. Teachstone created this professional learning activity to encourage teacher reflection and support adult awareness of and responsiveness to students' needs and cues.
