The most pressing need in early childhood mathematics education in the United States is to improve early childhood teacher preparation. A Web-based video system, "Video Interactions for Teaching and Learning (VITAL)", is a novel and effective approach for teacher preparation integrated into early childhood mathematics education courses. With extensive analysis of videos involving children's mathematical thinking, VITAL provides prospective teachers with engaging and intellectually stimulating hands-on and minds-on learning experiences that supplement the traditional textbook and readings.
