SAGE Research Methods is a remarkable new tool created to help faculty, librarians, and students with their research projects. SAGE Research Methods links book, journal, and reference content with instructional materials on research methods concepts that help researchers design projects, understand particular methods, conduct research, and write up findings.
The British Education Research Association and SAGE Publications have teamed up to create the BERA/SAGE Handbook of Educational Research, an excellent reference for all education practitioners and scholars.
