    Lecture Time
Click For Summary
The discussion centers on the diminishing value of traditional lectures in higher education, particularly among medical students who increasingly opt not to attend. Many students find that lecture content is often redundant with textbook material or easily accessible online, leading to sparse attendance. Some argue that lectures can be beneficial for real-time interaction and guidance from professors, while others feel that self-study and online resources are more effective. The conversation highlights the importance of personal learning styles, with some students thriving in interactive environments while others prefer independent study. There is a consensus that lectures can sometimes lack engagement and that the educational system may need to adapt to modern learning preferences, potentially shifting towards more flexible, self-directed learning models. Concerns about the high cost of education and the effectiveness of lectures in justifying that cost are also raised, suggesting a need for universities to reconsider their teaching methods.

Entire? All 5000 schools? That's nonsense. Does anyone really doubt that MIT is not Harvard is not Reed is not St. Johns is not Wellesley?

Meh, I see them enough in lab.

If you don't mind letters that say "He showed up in my lab but couldn't be bothered to show up for lectures."

Are you pulling down A+'s in the classes you're skipping? If not, there's a line from Bull Durham: "Think classy, you'll be classy. If you win 20 in the show, you can let the fungus grow back and the press'll think you're colorful. Until you win 20 in the show, however, it means you are a slob."

Personally I think lectures are an ancient practice that needs to evolve. We get the material taught "at" us for an hour and go home to read a book or the internet that does the same thing, teaching "at" us. For me, I'm a hands on learner. If you teach at me, I will know it for a day and tomorrow it will be gone.

Now if instead, the class was split up into groups to have the students provide the lecture with the guidance of the instructor (maybe with the instructor clarifying things that are obviously misunderstood, rather than wasting time on trivial subjects that everyone already knows about (maybe the book was pretty clear)). In this way, the instructor immediately see's his/her students' weak points. I think there would be a much higher rate of actual learning (opposed to temporary learning) with this sort of teaching strategy. I'm a firm believer that if you can teach the subject, you know it.

We're getting taught "At" from every angle there is, mostly commonly through commercials. I think it's becoming a pre-programmed thing in our minds to simply toss that stuff out the other ear, and with it goes the important stuff that we learned in that same exact way in class.

I think a lot of it has to do with the university I am at though too... Most of my classes have 100+ students. That makes it hard to really involve everyone. Not to mention, a lot of the professors are only teaching classes to fulfill grant requirements for their research. So if you fail, it's not the end of their world.

It's pass fail.

I wish my lectures will all recorded and online, however some of my teachers don't allow it as they want students to come to class. I would imagine my brand new 500 person lecture theatres for Chemistry and Physics would be quite empty if it was all online, and the class average would drop too. Let's be honest, a majority university students (especially first year) procrastinate and would pick sleeping in and partying over classes any day.

Not really. I always liked the lecture atmosphere and I get to ask questions that may seem confusing to me. You can't really do that and get a decent response whilst looking on a streaming version of the lecture.

Lecture is sometimes the only way to learn about a particular instructor's quirks. Off the top of my head, I remember a chemistry instructor who stated in a lecture that he considered all other physical sciences to be fields of chemistry. One of the questions on his test was 'Name 12 fields of chemistry'. Without attending his lecture and catching that throwaway remark, it would be very difficult to answer the question for full credit.

I think it depends on the lecturer, one of my professors just does nothing but quickly read off his power point slides. The notes are well written and great for review but he doesn't present it in such a way as to catch anything interesting or meaningful in the lectures. Other professors give very rigorous notes that you learn a hell of a lot from the lectures, it can be a hit or miss situation.

Its worth-while I think to see the professors approach to the subject. For example in my complex Analysis class the professor often presents the material in a way that intuitively seems a bit odd to me. However more than once doing homework I've been stuck and thought "how would professor X look at this" and was able to do the problem.

Maybe I'm arguing something different than everyone else. I'm saying classes in general suck. As far as I know, MIT, Harvard, Reed and St. John's all have classes in the same general way (lecturer gives a lecture while 10-300 people sit and listen).

Yes, but ultimately Professor X can always solve his problems by sending in Wolverine.

Perhaps for you. But the argument that's being made is that surely there is some university that approaches teaching in a manner that doesn't 'suck' quite so much. What about open universities or on-line or correspondence courses? What about reading courses? There are plenty of other options out there - particularly for the more common undergraduate courses.

The general teaching methods we have right now are heavily influenced by history. For hundreds of years lectures have been the most efficient way to convey complex intellectual information. They seem to have worked pretty well for students throughout history.

The only thing that's special about the current generation is easier access to information. We may now have the technological means to challenge the efficiency of the lecture hall teaching method, but that doesn't negate any value it has. It's a baseline that works. If you can improve on it - great. I think as educators we should be exploring that.

Right, in that case what I was talking about fits. I was arguing against the classical lecture-style classes. I fully agree with doing directed reading courses with teachers and other alternatives. What I'm confused about is Vanadium seems to think that the value of going to college is contingent upon how much you get out of the [literal] classroom.

Students should attend lecture because they, being humans, are social and intelligent animals.

The natural education system is set up with a classroom, social style focus, and as such most of us are used to the idea of going into a classroom, being taught by some authority figure (teacher) and then using that medium for interaction in education.

Chances are that if this was not the case, then we probably wouldn't be in this mindset. There are people who do not learn a majority of their knowledge/experience in this environment and still manage to be good at what they do. Not many people are like this, but they do exist and some particular industries have a bias for these kinds of people.

Also I think you'll find that people who have an inclination to learn by themselves have the advantage that they do not "require" coursework to learn something. They do not have the mindset that in order to learn, they must take a formal class on something to actually learn it and this is a very powerful advantage over someone else who is so used to the social system, that they think that learning and social interaction are both prerequisites for each other.

Sorry... I wrote up a well-sized reply explaining what I was talking about in my first reply to your earlier post. Your posts are these little one-liners that don't tell anyone about what you're trying to say. Maybe you should try and explain a little bit what your points really are instead of leaving it up to others to try and guess at it.

Well for example in my university i can say its almost a waste of time to go to class, the professors they just mind their work, some don't even bother to answer your questions because they just come to university when they give class, they don't really teach you something that isn't in the book so i would rather just read the book.

Now i think this is actually a good thing, not that the class is worthless but the fact that you have to study by the book because it forces you to learn how to absorb and generate knowledge, some people are too used to ask someone else as soon as they get a doubt, at least i used to but as the time went by i got better at clearing doubts by myself, so i barely now need a teacher to ask something for. If you think about it when you need to generate knowledge by research or something else in something new you won't have a teacher for that, at some point you have to do it by yourself so its better to learn soon.

So if class was a time of the day for the professor to tell you something he had gained by his experience in the field and not something that you are capable of learning by the book it would all be great, but it generally isn't like that. Also i would say its good if they would teach you how to '' read a book'' in the sense of to be critical about what you are absorbing and think about it and make conclusions about it, then i think it would be worth it (im no exactly sure how that would be possible i guess you learn it by watching your teacher deduce things from given info).
In change of that we get an education that every semester turns easier making most of the students lazier, which in turn makes professors care less about students and it just makes a vicious circle.

I can say in all my undergraduate time as ME i only had a good professor, he was the one that i had from Calc II-III-IV-complex analysis-numerical analysis and it wasn't because his class were great i mean he tried but he had to teach a lot from the book and didn't have time for lots of insight but when i asked him stuff outside the class he answered in such an analytic way of thinking, not the ''ok i solve your problem this way'' but he would really give meaning to what he was doing and i just really appreciate him for that.

PS English is not my language so i hope the idea is understood

If you present to me a good lecturer that can speak fluent english and can convey concepts in a way that I can understand then yes, I will go. However, this is not always the case. Most of the time I get more from skipping my classes and reading the textbook...

Well, I missed a huge fraction of my lectures in undergrad - and mine weren't recorded.
I found that most classes were either boring and too slow, or too fast so that all I could manage to do was scribble down the notes without understanding. Later I would be studying, but my handwriting is bad and I didn't like looking at my notes, so I would always read the book instead, and usually that was enough to complete the problem sets. In fact, piecing together some sparse information in the notes was usually much more challenging than looking at a full description in a textbook. So you see where that kind of experience can lead. Then you just get in the habit of skipping classes even though you probably would have gained at least a few tidbits from going.

I think I would have been able to benefit a lot more if I didn't have to write down notes, but it's hard to sit there without writing anything down if you know it's material you're responsible for.

Also if I would have read through the chapter a bit before coming to a class I'm sure I would have gotten a lot more out of it, but I could never manage to keep ahead like that.

I can't tell you how many times I got in a tough situation studying for an exam or completing an assignment, where I knew it would have been far easier if I had been to class. Ah well, it worked and I got into graduate school, and now I skip classes for the much more noble reason
of being in the lab.

I would say if I read ahead of schedule and maybe even worked problems before the upcoming lecture I would almost always get something out of it. If I was behind, then it was next to worthless because the lecture was too fast to follow without knowing anything beforehand.

One thing I would always try to do was to think before the professor. If there was a concept being written on the board I would try to think of an analogy for it. Or if there was a problem, try to solve it faster than the professor writes. Doing these things kept me interested and challenged during a lecture. I am a strong believer that only listening to someone talk about something will teach you next to nothing. The best method for me was to take info in, process it, then teach it to myself (by explaining it out loud) or to someone else.

I'm in first year engineering. For the first 1 1/2 weeks at the beginning of this term I went to all my lectures. I haven't attended a single one since. I learn best through self-study, through thoroughly reading the textbook and doing problems. Now I only go to my labs. So far I've been getting along quite well. I've had one midterm so far, in Chem, and did considerably better than the class average.

Lectures may benefit some, but they certainly are of no help to me. All of the profs I have just go through powerpoint presentations with stuff taken directly from the textbook. I honestly think lectures are more for people who are too lazy to actually read the book themselves and hope for just enough of an understanding of the course material to get by with a passing mark.

The way I see it is that lectures are free to attend. Literally anyone off the street can go, buy the book, attend the lectures, and learn as much or more than anyone actually enrolled in any given class. The difference is they can't write the exams, attain the diploma, etc. You're paying for that opportunity. The lectures are optional.

You can get a degree from 1000's of places. If you are not happy with the quality bof instruction where you are, why not vote with your feet?

This comes across as a little arrogant to me. People learn in different ways. And lots of people, if not most BOTH attend lectures and read the text.

Based on a single mid-term you've found a system that works for you. That's great. But why would you call someone lazy who learns in a different way?

You're equating "probably won't be escourted out by security" with "free to attend."

Wow, you must be extremely intelligent; you're only in your first year and you've already figured out that lectures are of no use to you. You have also found some way of knowing that all of your future professors and classes will be the same as the ones you're in right now. Incredible! Have you ever considered dropping the whole engineering thing and going straight for the Nobel?

You must have some very unqualified instructors.
Nothing compares to learning from an expert in the field; all of the most rewarding experiences in my academic life have involved interacting with my professors, either during classes/seminars, or in the lab itself.

Well, this is all very interesting. I reconcile high tuition costs by considering what I gain from lectures. There is one driving reason that keeps me going to lecture. Here it is...

Every professor is different and comes from a different place/background. More than likely they see something in a way that is unique. They see a concept from a point of view that most don't, and all professors have their own little jewel. AND! All you have to do is go to lecture to gain access to the their view of things. If I sit in a class an entire semester and only get ONE unique point of view or idea then IT WAS WORTH IT. Each professor can offer you something that no other can.

Feynman always talked about seeing things from a different point of view. Now, maybe you have a different goal with your education, but if you want to do any research or solve any new problems you need to see things from all possible angles, even ones you don't know exist... yet!

Best of Luck,
Eric

What makes an instructor qualified? A PhD? If yes, then you're probably wrong. If "good teaching skills/aptitude"? Then YMMV.

What works for you won't work for somebody else. I was watching a lecture on YouTube on multivariable calc (http://www.youtube.com/watch?v=PxCxlsl_YwY") and I didn't like it at all. Curiously, many of the comments for the video are positive and it's the first result that's returned on YT when one enters the words "multivariable calculus" in the search field. The cool thing with YouTube is you can close that tab and go view Berkeley's multivariable calculus lecture (I like this one better). It really sucks if you're spending bucket loads of money to attend an institution where the majority of your lecturers are not lecturing in a style that's not appropriate for you. Note: I'm not saying anyone is rubbish.

If I can't convince the admissions committee of US colleges A, B & C that I'm worth the money they're going to spend on me, I'm going *elsewhere*. Where it's dirt cheap, comfortable enough to live and where I can still get a good maths/physics education. At the end of the 3-4 years, I'll still be getting out of the program with something that says BS Physics, so what does it matter anyway.
