Online teaching and learning provide a flexibility and variety that brick-and-mortar classrooms just can’t match. Both students and teachers can work from home, or from anyplace they have a computer or mobile device. Additionally, online learning is generally much less expensive than in-person tutoring. And with a vast array of course offerings—everything from calculus to languages to social science—there is a subject for nearly every learning requirement or ambition.
