This report is based on the discussions of the February 2008 "Teaching by Choice: Beyond 2 + 2" conference, convened by the American Association of Community Colleges to focus on the growing role of community colleges as providers of teacher education and source of professional development for elementary, middle and secondary teachers of science, technology, and mathematics. The report includes recommendations for community colleges to expand post-baccalaureate teacher education programs and to enhance professional development in science, mathematics, and technology for teachers in kindergarten through twelfth grade (K-12). Some community colleges already offer these services to their communities. For most community colleges, providing post-baccalaureate and professional development programs is an extension of their traditional role as transfer institutions. The report addresses issues for recruiting and retaining K-12 mathematics and science teachers, for designing and delivering programs to place well-prepared instructors in the nation's K-12 classrooms, and for developing appropriate assessment and evaluation strategies for community college post-baccalaureate teacher education and professional development programs. A list of conference participants is included. [This text was edited by Lynn Barnett and Faith San Felice.]
