It should be noted that such a slick class has had the priviledge of being granted the kind of institutional suport which is extremely rare across higher education today, at least in the West. Being allocated the same module for 13 years? Having it be the only module you teach? Having an entire production team at the ready? It's a mistake to think this is one man's achievement, and a model to universities everywhere…

What's the institutional incentive to switch up the teacher of a module?

Ageist against whom? Gray hair isn't a problem image-wise if you are a professor nor is youth. I think the writer is just painting a picture.

Yeah, normally as quick to comment on casual ageism as anyone. But, in this case, it's the New Yorker and I think they're just humanizing the story. (And, per another comment, with respect to "knowing their audience" I expect the New Yorker readership skews relatively old.)

Humanizing the story via insulting/encouraging ageism toward a former MIT Chancellor (Grimson), and/or another well-known MIT Prof (Guttag) who is an expert in diverse CS sub-fields and has collaborated with the likes of Barbara Liskov? Given how long they’ve both been teaching and doing research, and how much cross-pollination there is between Harvard and MIT, it’s very likely both of them were influences on Malan himself.

FWIW, my wife also found Prof. Grimson to be “too monotone” and asked me “how do you stay awake during those lectures?” but without bringing age into it.

Side rant: I am the child of baby boomers, and I think their generation had it much easier than we do. I also get infuriated with the callousness and lack of empathy exhibited by many people from the Boomer generation. But rude retorts like “OK Boomer”, aside from being disrespectful, only encourage further callousness and lack of empathy.

Taking CS50 feels similar to watching a movie that has an auteur’s fingerprints all over it. Every word in the lecture, every technology, and every problem set has been carefully crafted to fit together to create a cohesive experience. College instructors everywhere should take the course to see what the zenith of multimedia online education looks like.

I've watched some of the lectures of CS50 in the past, and the one question that has always come into my mind is this: "How do these lectures help you learn at a deep level?" I already knew most of the material, so I found it to be an entertaining review, but that's different from a beginner needing to learn new material at a deep level. I kind of think it'd be a nightmare to take good notes while watching his lectur…

When I took the course as a near-beginner (someone who had taken programming 101 classes before but struggled to make anything useful), I found that jumping between languages frequently was more frustrating than helpful. Ultimately I moved on to something else. CS50 had high production values but I didn't find it superior in any other way. None of the content is bad, but I didn't get the feeling that many seem to have that its the greatest intro to CS.

Definitely didn't seem super beginner friendly after the first week or so. Perhaps I'm too slow at picking this stuff up.

1. There’s a companion C book for the course 2. The labs go into much more detail compared to lectures 3. The psets can be Nintendo-hard; you’ll be doing devilish pointer stuff by week 3 or 4. The happy-go-lucky, flashy tone of the course is completely misleading. It is a challenging course, so much so that it’s been the subject of numerous cheating scandals from students caving under the pressure over the years. As…

My comments were focused specifically on the lecture style - I just don't see the CS50 lectures as particularly effective. The students are almost certainly doing their learning by reading the textbook, attending the labs, and doing the problem sets that you mention. I have trouble seeing how the lectures contribute to truly learning the material. They're designed for passive consumption.

I wasn't referring to depth of topics but depth of learning. The latter is how deep you understand a given set of material. Passive consumption of an entertaining lecture doesn't help much.

> Still quite a bit of people decide to concentrate on CS after taking the class, so it must be doing something right in that sense...

That means it's optimized for recruiting folks to the field of CS rather than optimized for student learning. The only reason I've ever taken a class is to learn.

Usually it frees up the prior instructor to a) teach a more advanced course or one that's closer to their research interests rather than teach the same beginner level course over and over, or b) conduct research, which is why most tier 1 research uni profs took the job anyway.

Most major research uni profs are obliged to teach 2-3 courses per semester. Most would prefer to teach fewer or more advanced courses. Only those who love to teach revel in intro courses, and from what I've seen, that's less than 10% of profs at big name research-driven schools.

Perhaps people appreciate this course because the prestigious Harvard school is behind it. I would traduce that bias by "a good school involves necessarily good courses" . Is it true though?

My wife watched his class on the architecture of the internet. She’s not technical at all but was absorbed by it to the end.

And I never told her it was from Harvard.

well said. Prof Malan has achieved a great deal, for sure, but he does have that rockstar air to him which usually turns out badly when/if the press someday turns on him.

also i guess worth pointing out that it's win-win for Harvard to be giving this kind of support, with the attendant marketing it drives and the implication that if you take this class you can be the next Zuck.

Yes, this was noted in the article, which certainly does not proclaim that the CS50 model is the one that all universities and courses should be adopting.

"Malan’s contract at Harvard allows him to focus almost exclusively on CS50; even the research he publishes centers mainly on the class...Malan’s method of remote teaching is not easily replicable; CS50’s pyrotechnics would not be possible without an unusually deep well of resources and his own fanatical commitment"

> I'm not bashing the lecture style, but if I were a student, I'd prefer a good textbook to those lectures. I suspect you're in the minority here. The majority of students are more engaged by a good professor lecturing on material than by reading a textbook. This is especially true for introductory classes which CS50 is, because a lot of the students are from other majors and are being introduced to the entire field…

Me too. I'm not saying that in general textbooks are better than lectures, I'm saying the lecture style of this class is sufficiently ineffective that I don't see how it's worth anyone's time to watch. In contrast, Martin Odersky's lectures are designed to effectively teach the material, and they absolutely are better than reading a textbook.

The difference might be that I've always learned by taking notes and working through the ideas during the lecture. For those that are into passive lecture consumption, CS50 is about as close to perfect as you'll find. The style definitely doesn't work for me.
