CCT is conduct an evaluation of the ISS EarthKAM project's impact on middle school and undergraduate students in Earth Science research. ISS EarthKAM (Earth Knowledge Acquired by Middle school students) is a NASA education program that enables students, teachers, and the public to learn about Earth from the unique perspective of space. At the core of the program is a spectacular collection of digital images of Earth. ISS EarthKAM images are unique because middle school students take them. Using the World Wide Web, select middle schools request images based upon their classroom investigations. Since the program's inception in 1996, the ISS EarthKAM camera has flown on five Space Shuttle flights and taken almost 5000 images. The image collection and accompanying learning guides and activities are extraordinary resources to support classes in Earth science, space science, geography, social studies, mathematics, communications and even art. For its study, CCT will help NASA staff determine the degree to which the program is effective and addresses the relevant NASA education goals through study focused on learning outcomes across different grade levels and an adult sample. The study will employ a qualitative and quantitative approach.
