True, but incomplete. Filtering just EE/CS, there are 30 or 35 courses with full video lectures on ocw.mit.edu (which are all hosted on Youtube AFAIK). OLL seems to have four. Sometimes lectures are linked on a class website e.g. the modern Underactuated Robotics lectures: https://underactuated.mit.edu/ https://underactuated.mit.edu/ If you're going down the rabbit hole, search "site:https://video.odl.mit.edu/collections/ https://video.odl.mit.edu/collections/" or videolectures.net or archive.org, or you can search MIT's student pages for class assignments. Honestly, this is the only way to find substantial info on some entire fields e.g. Thermal-Fluids Engineering (2.005 and 2.006) ... or Course 2, in general. It helps to learn a specific school's curriculum (Stanford and Berkeley also have great resources) and target specific courses. You won't find lectures such as MIT's Inference course by looking on Youtube and OCW alone. [Not just replying to parent comment] If you plan to teach, sample some lectures by Patrick Winston, Anant Agarwal, Donald Sadoway, robert ghrist, and/or David Malan. The modern approach to engineering instruction seems to be 5 to 15 minute snippets posted online, but these five are among my favorite when it comes to full lectures.
