resting state fMRI

• Traditional in person teaching generally has characterists of: in person, lecture style, non-scalable, high cost, restricted access with a large amount of instructor interaction valued credentialing
• "Tranditional" online courses are online or blended online and in person and otherwise try to approximate traditional in person classes.
• Online interactive learning (OIL Code School, Code academy) primary characteristics are student-paced interactive learning
• Intelligent tutoring systems (swirl), like OILs just not necessarily online
• Khan Academy is online, interactive, scalable and low cost
• Other modalities : iTunes U, OpenCourseware, Udemy

Primary characteristics are open access, low cost, scalable, online
