INTRODUCTION
One of the biggest challenges faced by teachers of English Language Learners (ELLs) is
to help students achieve proficiency in academic language and vocabulary or Cognitive
Academic Language Proficiency (CALP). Every day in our schools a fast growing number of
teachers of non- English speakers search for an essential tool their students need to
continue their education. The missing piece is academic language. The vocabulary, grammar
and comprehension skills that will enable these students to read, write, and construct
meaning of subject specific texts (WestEd Education, 2008).
