The Children's Museum of Indianapolis has developed the Curious Scientific Investigators (CSI) program, which mixes the best the Museum has to offer with classroom instruction. Therefore, CSI’s vision is to support learning by all members of a classroom community, stimulate a lifelong interest in science, and demonstrate the museum as a place of investigation. The program targets three areas of emphasis: (a) guiding students in active and extended scientific inquiry, (b) developing teacher skills in integration of science knowledge, and (c) helping teachers implement inquiry strategies. The program combines the strong informal learning orientation of the museum with these elements of the NSES standards into a cohesive program that incorporates professional development, small-group inquiry experiences, student-centered learning, and content-rich experiences. These learning opportunities are grounded in the inquiry-based environment of the museum that promotes interaction and collaboration.
