An experimental study showed that a video feedback intervention improved the interaction skills of early childhood education and care teachers. The teachers who had received the Video Interaction Guidance training appeared more stimulating in their behavior, were more sensitive and more verbally stimulating than teachers from the control group. The training results were still apparent three months after the training. An analysis of the behavior of teachers at micro-level also revealed positive outcomes. These findings show that video feedback training for early childhood educators is a promising method to increase their socio-emotional support and verbal stimulation in childcare practice.
