Project LEAP (Learning English-for-Academic-Purposes) is a three-year faculty development and supplemental instruction partnership to improve the academic literacy skills of native-born, immigrant, and international language minority students. Course teams composed of discipline faculty, peer study group leaders, and professional language specialists enhance conceptually and linguistically demanding general education courses by (1) integrating content and language instruction and (2) helping students master complex academic literacy skills through guided, sequential learning tasks, with frequent practice and peer and faculty feedback opportunities. Students (n=576) participated in the 9 language enhanced general education courses; of these, 128 of the most high-risk students participated concurrently in complementary language-enhanced study group courses. Study group participants, despite skill deficiencies on entry, achieved course grades and course completion rates approximately that of non-study group participants. The programs' approach and materials are models for other institutions seeking to improve the success of high-risk, underprepared students. (Author/MSE)
