The findings from 20 years of research on undergraduate education have been unequivocal: The more actively engaged students are--with college faculty and staff, with other students, and with the subject matter they study--the more likely they are to learn, to stick with their studies, and to attain their academic goals. The existing literature, however, focuses almost exclusively on students in four-year colleges and universities. This special report provides summary highlights from a large-scale research project that examined, for the first time, relationships between student engagement and a variety of student outcomes--including academic performance, persistence and attainment--"in community colleges". The bottom line for community colleges: "Student engagement matters".
