Cognitive Academic Language Learning Approach

A program model based on cognitive learning theory, CALLA integrates content-area instruction with language development activities and explicit instruction in learning strategies (Chamot & O’Malley, 1994). 

CALLA emphasizes active learning, in which students are given the skills and opportunities to take an active role in their own learning. Developed by Anna Uhl Chamot of George Washington University and J. Michael O’Malley, CALLA is being implemented in approximately 30 school districts in the United States and in several other countries. Chamot and O’Malley (1996) report that some studies in certain districts show ELL students in "high implementation CALLA classrooms performed significantly better" (p. 271) than ELL students in low-implementation classrooms on the use of procedures such as problem solving. They do, however, acknowledge that more research and formal program evaluations are needed.
