A critical part of the Know, See, Do, Improve framework is the "Do" that is sometimes difficult to measure without being side-by-side with a teacher in her program. Early Educator Central provides the Head Start Coaching Companion, an online digital observation tool, to make it easier for teachers to “do.” As part of professional development, teachers can record their teaching practices. After digitally recording their own practices, teachers can share the videos with their administrators, coaches, trainers, and faculty as appropriate. The observation tool can be used as part of training, coursework, communities of practice, or one-on-one reflective supervision.
