The Lawrence Hall of Science (LHS), University of California at Berkeley has completed a 3-year project to develop a science and mathematics education course and science curriculum for early childhood educators. This project was in response to the need for improving the science and mathematics knowledge and teaching skills of adults who work with young children. The project conducted three 18-hour community college courses for 98 teachers. Eight Saturday workshops reached another 245 preschool educators. As support for the course activities, four teacher's guides and a handbook on early childhood teaching strategies were developed. The four teacher's guides have been translated into Spanish. The project materials were disseminated through 13 conference workshops for over 800 early childhood educators. The project courses, workshops, and teacher's guides were highly received by the 1,143 project participants and continue to be offered through LHS and local colleges. This project report provides an overview of the project, a section tracing the project from problem definition to project conclusion, information on the background and origins of the project organized into phases, a full description of the project and its courses, and an evaluation and project results.
