Thanks to the internet and MOOC (massive open online courses) culture, it's not hard to find courses from prestigious universities such as Yale online for free or cheap. Counter to the Ivy League's legacy of exclusivity, MOOCs are designed to remove traditional education barriers: price and location. In fact, Yale offers access to a handful of recorded in-person courses such as African American History: From Emancipation to the Present via Open Yale Courses, a platform where anyone can access the lectures. However, lecture-listeners won't earn course credit, degrees, or a certificate of completion. If you're looking for a classroom-like educational experience with more structure, feedback, and peers, you'll want to turn to Coursera. The online learning platform features more than a dozen Yale courses that range in topic from economics to parenting to happiness. Coursera classes typically include video lectures, resources, community discussions, and quizzes. They're free to enroll in, but you'll have to pay a low fee (starting at $49) for features like graded homework assignments or certificates of completion, which can be added to a LinkedIn page. Based on the most popular course in Yale's history, [The Science of Well-Being] combines positive psychology with the real-life applications of behavioral science to increase your own happiness using concrete, productive habits.
