Lecture Hall Back-Channeling 297
emmastory writes "The New York Times is running a story on the phenomenon of lecture hall back-channeling - now that many conferences and universities have wireless access, some people discuss lectures via instant message or weblog as they happen. Although the article quotes an instructor at NYU, I haven't seen much of this in lectures I've attended there. I would guess it varies from department to department, but laptops aren't yet as common in classes as one might think. Either way, some people consider the practice rude, others consider it progress, and good arguments can be made on either side."

The process was quite interesting and helpful for me since it allowed me to interact with other participants and gain new perspectives on the session topic.
I could see how a lecturer might not appreciate Hydra, blogging or anything else like it since it could basically be a way to silently pass notes, chat, and otherwise not pay attention to the lecture. But, there isn't much the lecturer can really do other than making it important to listen and pay attention.
University must be too easy (Score:3, Interesting)
Maybe it's a matter of course material. I don't honestly thing that University is getting any easier--probably the opposite in fact--but laptops and wireless might be leading the charge away from frantically taking page after page of notes with a cramped hand, while trying to absorb the information at the same time. If so, it's probably a Good Thing. (Of course, some fields are harder to move to the computer. Writing out the formulae in phys. chem. and quantum mechanics strikes me as still a pen-and-paper exercise)

Also, it would be great to get WebEx or Netmeeting or something like that working with it too to provide interactive whiteboard/diagram support. Perhaps even interacting with Smart whiteboards like are installed at my University, perhaps the whiteboard could be input realtime to each of the laptop clients logged in. This would make it easier to see diagrams from longer distances, allow students to save the diagrams for studying later, and would also allow realtime feedback if a student had a question. (i.e., they could draw a circle around the trouble area momentarily.).
Neat stuff!

I've certainly known it happen at many conferences. People will often look up the website of the speaker, try out their tools, look up their papers while they are speaking. A very good thing.
Of course others do spend lots of time checking their email, or doing other work. But this is the nature of the beast. At many conferences most delegates are not interested in all the talks, but you often do not know whether you are or not, till a couple of minutes in. So now the choice is between listening to something you are not interested in, or email. A improvement from when you could listen, or fall asleep....

Since we were spread out across several floors & buildings, we had a telnet chat server running, basically doing IM functionality.
We got into the habit of holding tech-only meetings via this server, with following benefits:
- Less waffle, it's harder to digress on a keyboard
- People actually thinking before "saying" something
- Instant meeting minutes (a GREAT bonus)
Unfortunately, this only works if ppl can actually type more than 5 words per minute, hence I don't forsee this reaching the mainstream anytime soon.
Only very few of the managers understood the benefits, the natural assumptions was geeks+network+server = "this can't be work, they must be playing"

It seems that in the CS and EE classes that I take, the profs are pretty glad to see students taking an active role in the lectures rather than just sitting and obsorbing information.

Pulling your laptop out in class seems to get the same reaction as if you pulled out an assault rifle.
*lecture*? (Score:5, Interesting)
I've heard some fairly good arguments to suggest that the lecture itself is a mediaeval form of presenting information and is now out of date as a way of transforming knowledge. What do students gain by sitting listening to the great master spout his wisdom?
Several lecturers I know have moved to providing their "lecture" online (e.g. hypertext document) and use the allocated lecture time for a follow up workshop, requiring the students to have already read and considered the "lecture" and to come along with some sort of academic response. Seems a far more effective use of teaching time to me, far more likely to be of value to students.
RIT IT Wifi Everywhere (Score:5, Interesting)
Our entire building [rit.edu] (three floors, just recently expanded) is covered with 802.11b connectivity. Many of the students, including myself bring laptops to class. Sure, some kids abuse them, and surf or play games during lecture (I've been known to do the former during a very boring Intro to System Administration 1 class [rit.edu]), but there are some excellent uses.
I think the best is checking on something taught in class. More than once in that System Administration [rit.edu] class the teacher has mentioned something, I doubted it, googled for it, and either learned it to be true (there was a use for the sticky bit to keep programs memory resident, but in current linux the sticky bit's purpose has changed), or false (Windows 2K does NOT require NTFS to do software RAID -- you can use FAT just as easily). This is an excellent way to reinforce information being taught. Had I not had my laptop in class I would've gotten sidetracked, forgotten about it, and never learned the truth about these and other things.
In another class I took, Network Administration [rit.edu], the teacher, Bill Stackpole [rit.edu], would often take advantage of those in class with laptops. If he brought up a topic and wasn't sure about something he mentioned, he'd encourage those of us with laptops to research it quickly, and let the class know the correct technical data. If a student would ask him a question in class that he couldn't answer, he'd encourage anyone with a laptop to help out and find the answer. From even those few excellent uses of wireless connectivity in the classroom I feel its been a great addition to the technology classes at RIT. If someone is going to goof off using a laptop, then they are the same person who was going to goof off doodling in their notebook, nothing lost, nothing gained.
I could go on and on about the times the Wifi access has saved my ass in one way or another in the GCCIS building. (and maybe I will later) Come out of the wood-work RIT students -- I know you have more stories!
Tutorials in the Humanities (Score:4, Interesting)
That's been part of the teaching style of the humanities for a long time now: go read this paper or book by some smart dead dude (readings), then I'll tell you what I think about it (lecture), then we can discuss (tutorial).
It's pretty obvious that a lecture can be converted to a meta-reading and put online, but the big question right now is whether tutorials can also be as effective online. Of course, never underestimate a university student's desire to be passive: many would rather snooze through a two-hour lecture than spend that time reading. And tutorials at anything below an advanced level are pretty dismal, at least at my alma matter: two students team up with the professor to mock the one student who will actually voice a minority opinion, while the rest snooze.
If the Internet can fix any of this, I'm all for it.

The Laptop Dilemna (Score:5, Interesting)
I used to use a laptop in class, but found it ultimately more trouble than it was worth. It worked fine for the English elective (waste of time) or the History of Science courses I took, but not for my core Math & Science classes.
Basically, by the time you copy out a diagram or complex formula, it will take you so long (especially if you have to switch to Symbol to make half the characters), that it's simply not worth it.
Now, some profs distribute their lectures in PDFs/Word Documents/HTML files, which makes it much easier, but then many students just download the lecture notes and skip class, which professors tend to hate.
I think a great solution would be for all students to have wireless laptops, and have the prof stream the lecture to students as he goes. That way, there's an incentive to go to class still, and laptops become a worthwile tool.
I'm thinking along the lines of a custom program that feeds one page at a time into a PDF or something.
Alternately, documents with blanks spots to be filled in during the lecture can also work.
Or, finally, something like the Mimio [mimio.com] would also be very cool.
Possible problems... (Score:2, Interesting)
I have had a few different lecturers over the past three and a half years, some I remember fondly, others I remember in pain. I have suffered through hours of lecturers from people who I cannot understand (that was not intended to be racist, and anyone who takes it that way is a moron) I just cannot understand what they are saying due to their accents... it makes it very difficult to learn.
One of my favourite lecturers, teaches by making the students THINK. This is a practice that is uncommon in the university world. A student is more likely to pay attention and learn if they are involved in the lecture. He would tell stories from industry, teach the course material, and then in the lecture would ask the students questions. What a novel idea... why don't more lecturers follow his example? I can tell you all with absolute honesty, that I have retained far more knowledge from his classes than from all of the other classes combined. He has found a way to make his material interesting to the students. This encourages them to learn... to think... many lecturers just expect you to absorb the information, and then spew it all back to them verbatim. Thought appears to be disencouraged.
I must apologise now for the seeming randomness of thought there. I feel rather strongly about this, and can get a little excited and begin to ramble.

While I saw and was part of some of the type of on-topic conversing going on back then, it wasn't a large part of the usage of the laptops. Aside from where they were explicitly used as part of the lecture, I used mine for about 1/2 on and 1/2 off topic.
For instance, during math and science classes it was very useful to be able to do and play around with complex calculations quickly while a lecture was going on. The ability to do bits of research in realtime helped too. And yes, some real-time conversing on the subject.
I guess some of my usage fell in-between on and off topic. Things like working on homework for that or other classes, being able to do little bits of work on projects as you happen to think of things during classes, speaking with or emailing team members, that kind of thing. Education related, but not necessarily related to the topic at hand.
As for off-topic, that ranged from emails to web surfing to playing network games with other people in that and other classrooms around you. 95% of that probably happens in the first quarter of school, though. That kind of goofing off drops off pretty quickly as the novelty wears off and as you realize just how much you're paying for that time. Many (probably most) of the profs were too intense to be able to do other things anyway.
I've recently learned that my high school [bsu.edu] will begin requiring/providing laptops in this coming school year. The whole campus is already bathed in 802.11b goodness. It will be interested to see how *that* turns out...

The big reason the computer helped is that i could search through them insted of skimming my aweful handwriting.
I think the tablet would come in useful as you could do those drawings where needed, type where needed, etc. I know there is no handwriting recognition software on earth that could decipher my chicken scratch, but it would have negated my need to waste paper.
I do agree that most people will just use them to play games, and have had profs make people turn off the monitors while class was going on because the clacking was annoying, and people wernt paying attention(which drags everyone down). Maybe in class there could be wireless that isnt open to the outside world, so im and browsing could be cut off at the will of the instructor. But that gets into other issues. Just a thought. Might try the tablet when i go back for more degrees.

Agreed. I took a chemistry course like this several years ago. This course had reputation for being extremely difficult and you heard scary stories about it around the lunchroom table. The people who actually did the work before the lecture (including myself) did reasonably well (70-90%, and 80+ was a flippin' good mark for that class.) The people who fell behind on the readings were in a pit too deep to possibly climb out. They dropped, failed or barely squeaked by.
Of all the courses I have ever taken for anything, I think this chem one was the one where I learned the most. I liked the format because it really causes the information to stick in your head. Also, it weeds out the people who are not committed and really forces everyone else to actually learn. Four years later I was helping my brother learn the same stuff and I could correct or guide him on the material from memory because I remembered it.

Re:*lecture*? (Score:1, Interesting)
First about the "knowledge". Often as you say the material is available online or as course literature. With some reading instructions you can easily get the same amount of knowledge on your own. Maybe the lecturer can clarify one or two things but these occasions are rare at best (unfortunately). This isn't about the knowledge.
For me however these are the reasons for going to lectures:
1. Consistency
I _know_ I don't have the self disciplin to actually study enough on my own. Lectures give me regular times of studying and if I go to them all I know that I will at least have learnt something. Something I've been starting to experimenting with is to take my book along and actually read _at_ the lecture instead of listening. This has the advantage that I will get good use of my time and if the lecturer actually comes up with anything interesting I get to hear that as well.
2. Dialog
If there is something unclear I can take it up with the lecturer. You can do this on your own of course, the lecture just becomes a natural meeting point. To be honest, students of computer science seems to be terrified at the thought of asking questions (at least so the whole class hears), I often think that this comes from being insecure in what we actually know. And shyness of course. Or they are of the other sort of course, the ones that "knows" that they know everything there is to know. They never ask questions, instead they just have to have some irrelevant remark that shows just have good they are.
3. Social
I actually like to meet people. I wan't to be able to talk a bit in the break, not necessarily about school, or before and after the lecture. Study groups are often created this way which is great (once again this is something that computer students often seem to underestimate, perhaps because of the same reasons as above).
So, while lectures might not have the same information spreading purpose that they had once but they are still very important.

This is a suprisingly good idea, since the material that is being presented at _________(college name left blank so as not to offend) is not really at the level that a normally intelligent person should have to pay more than minimal attention. The downside is that there are only 3 ppl with laptops in class, and no easy to use network protocol for chatting in class, so very little class work gets done.
Another benefit is that I can look up subjects and read about them while ignoring questions that are being asked for the 2nd and 3rd times.

I'm not sure how I feel about this... I like the professors' readiness to use technology (one would hope that would occur, considering which course it is!), but I can see how many students would benefit from a traditional lecture format.
