Registration is now open (until October 1st) for this free, eight-week, massive open online course (MOOC) offered by Oregon State University. The MOOC is designed to help teachers support English Language Learners in meeting new, rigorous standards. The course will focus on a key practice within both the Common Core State Standards and new ELPA21 English Language Proficiency Standards: constructing claims supported by evidence. This MOOC is endorsed by the Oregon Department of Education for Oregon K-12 teachers, and the content is also open to teachers outside of Oregon (especially educators in the ELPA21 consortium). This MOOC is collaborative effort among the Oregon Department of Education, the Stanford Graduate School of Education, Understanding Language, and Oregon State University.
