The study focuses on general academic vocabulary, which is most challenging for ELL students. It explores using morphological analysis and cognates to help students unlock meanings of new words. The study involved vocabulary lessons with 6 Spanish-speaking ELL high school students. Data was collected through pre/post-tests, surveys, interviews and student work to analyze the effectiveness of the instructional strategies.
