		<description>We install blackboards at our University (University of Toronto) because:
low maintenance
wide appeal (not all, of course)
low cost
no training required

Whiteboards are more visible, but have the marker-cap and smell issues. so they are not as bullet-proof. Electronic options are great - but require training and have down time. Of course, with a screen in front (hopefully allowing for the screen and part of the blackboard to show at the same time), a number of the electronic options can occur in conjunction with blackboards. So we use the blackboard as the &#039;lowest-common denominator&#039; interface. It is not the best for all. But in terms of being a reliable base level for the greatest number, it is very effective.

A number of the comments above fall into concerns about which is the best or worst teaching method. Of course, most rooms or blackboards will outlive one user, and everyone will agree that not all teachers should be forced to teach in exactly the same way. So it comes down to providing options to accommodate many styles of professor and student. When I spec a room, I want as much blackboard as I can get on the front wall (24&#039; sounds good to me) - and then we can start worrying about the harder parts; data projectors etc.

When I was a TA, if I didn&#039;t want to use the blackboard, I&#039;d just go digital. I almost never used the blackboard myself, except for posting  announcements etc. But I&#039;d spec it in a room every time.</description>

		<description>Well, I share the hate of real blackboards; chalk dust is one of the very, very few things I seem to be allergic to.  Love whiteboards but understand why some people don&#039;t like the markers.  and I NEVER, EVER make my notes available (I can understand how that works for upper division and grad classes though; my best class in grad school was taught by an atrocious lecturer who had the good sense to make his hand written notes available) as I sorta want my intro students to actually show up.  but I tell them the truth:  aside from simulations and movies etc., mostly my slides are for MY benefit and they should NEVER, EVER attempt to copy slides down verbatim.
    Interesting factoid: try writing on the board (of any type) with your off hand.  You may be surprised by the results.</description>

		<description>Wow I never realized my physics department was such an anomaly here- we have a historic building meaning during renovations a few years ago there was a fight to keep our blackboards to the jealousy of surrounding departments (in large part because whiteboard markers always seem to be in critical shortage, whereas chalk never seems to have that problem).  And now that I TA this year I too write on a chalkboard and find it much more satisfying than the alternatives!</description>

		<description>I like whiteboards for small groups, and one on one discussions, or for personal use.  But Powerpoint rules the day when it comes to presentation and explanation.  There&#039;s a lot of cool tricks you can do with powerpoint, and I rather like spending my time trying to explain that what I am saying makes sense.</description>

		<description>The magna doodle idea I have seen implemented in Kyoto. Actually, the company that produces the board is not Japanese, if I remember correctly. I want to buy this board for my office, because can&#039;t stand neither the chalk dust, nor the smell of the aceton. Strangely, I cannot locate the company on google (tried various key words). Probably, because this type of board is not very widely used.

ps: the board is about 4feet x 6-7feet and it costs quite a bit.</description>

		<description>Julianne,

Yes good idea! LOL!

I was laughing my head off your comment!

(At first, I was going to put what you said too, or expressive dance at least, before the silly comment I made). Of course I was just being jokey and for that reason I actually think the Magnadoodle idea is very good. 

It&#039;s a difficult one as it&#039;s your job day in day out. Maybe you could have a chat with your University bosses to see what they can arrange. It&#039;s been a while since I have been at Uni (early 90&#039;s) so not sure what the situation is with regards to how lecture theatres are kitted out these days, especially in the US. 

Cheers,

Claire</description>

		<description>Magnadoodle is fine. But chalk and blackboard is still the low cost, low tech, low energy, renewable solution. 

Chalkboards are little more than plywood and a specialized paint. Chalk is very basic. Expenditures in energy and oil for both are fairly low. Magnadoodle, not so much. 

You have a point about visibility of chalkboards but this just suggests small class sizes. Perhaps some sort of technical improvement in chalk to make it more visible.</description>

		<description>I once had a math teacher with wild, flying hair and a weird german/polish accent. Class was in the 2nd floor of an ancient building with large triple hung windows. He worked on this long stage/riser that was level with the window sill, and the window was open because we didnt have A/C and it was spring. He would race back and forth, madly deriving Laplace transforms, and we were always afriad he would get so excited he would fall out the window. NOBODY missed a class. 

Try THAT with powerpoint.</description>

		<description>If you&#039;re worried about getting chalk dust on your clothes the obvious solution is not to wear any. I&#039;m sure that would also increase attendance at your lectures.</description>

		<description>One of my best physics classes was a Stat Mech class where the professor made the notes for the semester available at the beginning of the course (bought from the university printer).  He encouraged everyone to buy the notes, and pretty much everyone did.  The notes were good enough that it was nearly verbatim what he said in class. At first I felt like I should be taking notes, but after a while, I just learned how to annotate parts that confused me.  The class was much more productive than normal - all of us actually listened to understand during the class and people asked questions when the didn&#039;t understand.</description>

		<description>@17 and @18:  I should elaborate:  several studies[insert missing references here!] have shown that you can do best by not taking notes during the lecture, but rather listening and participating (I ask discussion questions once or twice during a lecture).  Then, that very same day, that evening at the latest, print out the copies of the slides and annotate them.  Don&#039;t wait for the next day or you will forget things.  The important thing is that it appears that writing and listening (for comprehension) tend to be incompatible.  Too often I see students who are so intent on writing down everything that they don&#039;t even know what it is that they are writing.  And, by the way, I have tried put up my slides ahead of time, and I still see people writing furiously on them.</description>

		<description>Julianne, 

My advice would be to replace blackboard - chalk/whiteboard - markers/overhead projector/computer white board - projector/magandoodle/crayola coloured crayons with a large metal board (white or black - black if dyslexic as I am) then use those coloured magnetic alpabet letters and notations - those used on fridges. For pictures you could use long bendy ones or even putty. You could create three dimensional visual effects with the putty, for the students to see theories better with, thereby cutting the amount of space used on a flat vertical plane, that otherwise would be used when writing things like inverse square law eqations. The putty will have ferrite mixed with it so would have to wear gloves over along period of time. In that case, the gloves could have an in built microphone (on the back of the hand area) whereby the sound from the lectuer, reaches the students at the back of the lecture hall.&lt;- less of an excuse for not handing in homework.

		<description>At my university, several rooms employed a projector and a camera.  You wrote in ink, on paper, and the results were displayed on the screen.  Need a fancy graph?  Get the source and show it.  Flip a switch and you have your laptop screen displayed instead.  It worked great, and it allowed dust-averse professors to lecture with something besides PowerPoint, which might as well not be lecturing at all.  Established, versatile technology.  Why you would do anything else is beyond me, though it does work better if you&#039;re right handed, since your hand isn&#039;t covering what you just wrote.</description>

		<description>Ever used the magna-boards at length?

I have, in a classroom setting (with 25 2nd graders doing math or literacy).

They&#039;re not that great.

The writing tends to be messy in appearance, the resistance thing is even weirder than whiteboards, the &quot;erasing&quot; with the magnet poses problems, and above all, they don&#039;t last. With second graders having personal slates, at least, after a couple years the magna-boards are barely functioning as writing platforms.</description>

		<description>I hate whiteboards. Chalkboards generate more dust, but it&#039;s inert stuff that you can pat off or dust off fairly easily. Whiteboard dust from dry-erase markers is nasty sticky stuff that smudges books and stains clothes. (And stinks.)

My experience with handwriting is the same as those who say it&#039;s neater on a chalkboards. The friction level is right for me, resulting in better handwriting and neater drawings. Chalk is my medium and I hate it whenever I&#039;m scheduled to teach in a whiteboard room instead of one of our remaining chalkboard rooms.

One of my colleagues recently asked when we would &quot;finish&quot; getting rid of the chalkboards. Over my dead body.</description>

		<description>&quot;Students in the back can’t see what you write&quot; when writing on a black board with chalk, says Julianne. From my experience this is absurdly false. I recognise then many, many advantages of white boards over black boards (almost all of which come down to one thing: dust), but the one thing that still makes me prefer black boards when I&#039;m in the audience is legibility, especially  at a distance. Size, contrast and handwriting all tend to be better.

However, as a few people have mentioned, it is neither necessary nor particularly desirable to always rely too much on black/white boards. You can prepare your lecture notes beforehand and post them for the students to print, and then you can use projectors, boards, transparencies or whatever happens to fit the lecture best.

And Bob, I think you are making a big mistake by waiting until after the lecture with posting your notes. Especially if you want the students not to take notes. It is the best thing ever, in terms of taking notes, to have your own printed copy of the lecture notes with you to the lecture. Then you can follow the lecture and listen to everything while also keeping an eye on the notes. Then you just have to fill in whatever extra information you get from the lecturer that you want to add to the notes. If you only get the notes afterwards, you still have to try to take your own notes during the lecture because you don&#039;t know what you get otherwise.</description>

		<description>&quot;I try to convince the students not to take notes, but to try to listen to what I am saying (and to watch the demos)&quot;

My mind doesn&#039;t retain anything unless I take notes.  And notes I can refer back to years later.  

Whiteboards are ideal.</description>
