'The Traditional Lecture Is Dead' (wired.com)
Rhett Allain, an Associate Professor of Physics at Southeastern Louisiana University, writing for Wired: What is the traditional lecture? It is a model of learning in which a teacher possesses the knowledge on a given topic and disseminates it to students. This model dates to the beginning of education, when it was the only way of sharing information. In fact, you occasionally still see the person presenting the lecture called a reader, because way back before the internet and even the printing press, a teacher would literally read from a book so students could copy it all down. Now, don't get me wrong. The traditional lecture model worked wonderfully for eons. But it is an outdated idea (free pass for adblockers). Close your eyes and imagine yourself in a college physics course with a professor giving a traditional lecture. Now open your eyes. Did you envision The Best Physics Lecture EVAR? I doubt it. You probably pictured someone droning on and on in front of a chalkboard or PowerPoint presentation. No way that is more engaging or interesting than an episode of The Mechanical Universe , and if you're a teacher who uses traditional lectures, just stop and play the show instead. Everyone will be better off. You may think by now that I think most physics professors are dolts. I promise that's not the case. But traditional lectures simply aren't effective. Research shows students don't learn by hearing or seeing, they learn by doing, a model often called active learning. Physics faculty should start thinking about how they can go beyond just a traditional lecture. There are some easy things they can do (or students can ask them to do) to make learning more engaging. First, make students read the book outside of class, rather than in class. If your lecture merely covers the material in the textbook, why make students buy the textbook? Now, you may put a different spin on the material, but still. You're merely repeating what students can read on their own. Let them do that on their own time, and use the classroom for experiments and demonstrations and so forth.

Speak for yourself, a good lecture reduces the time to learn for many. For me, I figure at least 2x. The interactions rapidly clarify areas of confusion.
A great lecture inspires.
Wrong.
Beyond Wrong.
"The Mechanical Universe", what the fuck I don't even.
Fuck off with your hipster pseudo-intellectualism. Here is a lecture on hydrostatic pressure by Walter Lewin. It is more interesting, more entertaining, and more educational than ANY of your pop-science crap. I don't care what privatised iCloud lecture service you are trying to hock, or your bullshit smear stories against Lewin either. The traditional lecture format is better than anything you can come up with with your cheap credit funding and fly by night websites and social media scam promotions.
Get the fuck out of of my fields. Get the fuck out of my hobbies. Get the fuck off the internet you anti-intellectual Hipster frauds!
This type of response is why education in the US is off the rails. You extrapolate your response to learning via YouTube to the entire student population. Students learn differently. Some respond to visual learning methods. Some to auditory methods. Some respond best to experiment. The point being, instructor input is vital. During a lecture, the instructor can see the "deer in the headlights" look, and adjust the instruction style and content appropriately. Videos can't do that. Self-study only works with brilliant, entirely self-motivated individuals, and those are rare indeed.
Speaking as a physics professor who has tried many of these new techniques - I've done video lectures which are up on YouTube, in-class tutorials, clickers etc. - I get really annoyed by this type of hyperbolic promotions of them. Technology has indeed given us some better ways of doing things and in that the OP is right that we should explore and use them. However, somethings are best taught in the more traditional lecture format and frankly, when I was a student myself we were all supposed to read around the subject - not just limited to reading the textbook but other books too - as well as attend the lecture so this is hardly a "new idea".
In particular one of the things I have noticed with many of these new techniques is that they communicate far less information and those using them often have to take material out of a syllabus. They then compare this to the original lecture and it is no surprise that they find that students learn the material better. However if the original lecture format was repeated with the same reduced syllabus and far more time on each topic I expect that this too would get better results if for no other reason than students have less to revise for the exam.
So please let's not start the irresponsible hype that old lectures are dead just because we have an arsenal of new techniques. Some of these techniques may have disadvantages over the "old" lecture style particularly when it comes to the amount of material covered which, for a subject like physics, is extremely important because it has a more linear nature until you get to the final undergrad year. Plus some of the new techniques are grossly unfair since they award marks for a group and not individuals which means it can be heavily influenced by how lucky you are with your group members.
You need the lectures, the tutorials, the 1 on 1 time and a varied approch. All of these things happen now at the university where I work. There are all kinds of learning and activities put together in the LMS, online. The lecturer is still required and the subject mater expert and the lecture is part of effective modern learning. One thing though is to limit the length of the lecture and keep in mind that its not the whole story. However its far from dead - thats just click bait headlines.
