With funding from NSF, the Prime the Pipeline Project (P[cube]) is responding to the need to strengthen the science, technology, engineering, and mathematics (STEM) pipeline from high school to college by developing and evaluating the scientific village strategy and the culture it creates. The scientific village, a community of high school students, teachers as learners, undergraduate students as mentors, and university scientists as leaders, collaborate to solve challenging long-term problems/projects that develop villagers' expertise with STEM concepts/skills and give them a taste of the work of STEM professionals. Data were collected from both a group of intervention students and a matched control group to address the research question, "Does participation in P[cube] increase students' interest in and success with the study of mathematics and science in high school?" Data were collected through surveys and interviews to address the question, "Does participation in P[cube] change teachers' instructional practice and expectations for student performance?" Results showed that intervention students completed significantly more and more advanced courses in science and mathematics in high school, and their GPAs were significantly higher than their matched controls. Surveys of students' postsecondary plans and intended college majors confirmed increased interest in STEM or business fields. (Contains 9 tables.)
