Why it's hard to close learning gaps

Student behavioral issues are a major barrier to closing learning gaps, say 67 percent teachers in a Khan Academy survey, reports Lauraine Langreo on Ed Week. Another 57 percent chose "student mental health."

Khan Academy's blog stresses teachers' support for mastery learning to help address learning loss. Most teachers would like to let students advance at their own pace and retake tests until they can show competency in a subject. However, many say rigid pacing guides make it hard to spend more time on a concept if it's needed.
