By Salman Khan Every day during the academic year, tens of thousands of students across the country sit passively in 300-person lecture halls listening to 90-minute lectures on freshman or sophomore-level calculus, chemistry, or biology (and this isn't even counting the students who have decided to punt the lecture altogether). Some students take notes to keep up. Most are lost or bored or both, trying their best to stay awake. Professors stare at a sea of blank faces while delivering a lecture not much different from the ones they have delivered in each of the past 10 years. Students go back to their dorms to work on problem sets in a vacuum. They fight through 1,000-page, 10-pound tomes to get at the nuggets of information they really need or can comprehend. Many give up and copy from their peers. This cycle continues for several weeks, until just before the midterm or final exam, when students cram everything they should have learned into one or two sleepless nights. Regardless of whether they can prove proficiency in 70, 80, or 90 percent of the material, they are "passed" to the next class, which builds on 100 percent of what they should have learned. Fast-forward six months, and students are lucky to retain even 10 percent of what was "covered.""
