A Bad Apple in the Classroom? Know It To Change It

Recently, I was part of the Global Economic Symposium held in Rio de Janeiro. This year’s theme was Growth through Education and Innovation; I presented as part of a panel entitled Effective Investments in Education.

My presentation focussed on the fact that a growing and compelling body of research shows that teacher effectiveness varies widely - even across classrooms in the same grade in the same school. Getting assigned to a bad teacher has not only immediate, but also long term, consequences for student learning, college completion and long-term income.

Can Public Accountability Motivate Teachers to Perform at their Best? The Conversation Heats Up

In recent weeks, several articles have appeared in the main U.S. newspapers– including the Washington Post and the New York Times – discussing the potential benefits and pitfalls of the Los Angeles Times’ decision to publish performance data on individual teachers.  Together with an economist, LA Times’ reporters used long-existing data on student test scores by teacher over time, to estimate individual teachers’ “value-added”, that is, the change in a student’s test score in the year that they had a specific teacher, attributing this change to the teacher’s effectiveness. They found enormous variation in the change in scores of students of particular teachers, and published the names of some teachers – both the “best” and “worst”.  Further, the paper announced that it will soon release the approximate rankings of all individual teachers in LA.


Will public accountability of individual teacher performance contribute to improve education quality in Los Angeles? Is this something that other education systems around the world struggling with finding options to raise teaching quality and student learning outcomes consider?
