Kenji Hakuta, Professor of Education at Stanford University, is offering a new free Massive Open Online Course (MOOC) in May, intended for instructional coaches and leaders. The curriculum will focus on formative assessment practice to support the language demands of the Common Core State Standards. In this introductory course, participants will learn to systematically observe student language through data collection, analysis, and group discussion. Data collected and insights gained throughout the course will contribute to the design of a more comprehensive formative assessment course expected to serve teachers in fall 2014. Dr. Hakuta will be joined by co-teachers Jeff Zwiers and Sara Rutherford-Quach, researchers at the Understanding Language initiative. Additional information is available on the Understanding Language website.
