that is supposed to erase a message is the Escape key. @: Message 9: exactly the same & Message 6: Slight problem & Message 9: To whole message & Message 6: To whole message |

| Annie,
12:38 (13.06): We are running it on our server and would likely be
happy to support something like that. Johann knows more about the
official status of the software, though. @: Message 15: To whole message | | |
|
| 17 |
| | zebroid, 12:39 (13.06): Great. This has all sorts of potential. Are he developers looking for a testing site? | |
|
| 18 |
| | | JohannMF,
12:42 (13.06): We are very interested in runing pilot programs with
this software as we learn more about how it can support collaborative
problem solving and other uses. We can talk more after the Tool Fest.
@: Message 16: To whole message & Message 15: To whole message |

| | | JohannMF,
12:45 (13.06): One thing that I would suggest is to try to use the
upper left corner as your reference point for new images as people may
have very different screen sizes and it gets a bit difficult to predict
how far down (or to the right) they can actually see). @:  |

|
| 41 |
| | | | Gene,
13:35 (13.06): This looks quite interesting but maybe we should call
our week the Cutting Edge Tool Fest! Still, lots of potential. You must
have had a grand time with this, Jon. |
|
| 42 |
| | Suzanne, 13:39 (13.06): Gene we haven't actually started yet - the session starts at 2:00 | | |
|
| 43 |
| zebroid, 13:41 (13.06): Johann, Did you get my message about not being able to delete items from the whiteboard. | | | | |
|
| 44 |
| zebroid, 13:42 (13.06): Did anyone get my message about not being able to delete maerial from the whiteboard? | | | | |
|
| 45 |
| JohannMF,
13:45 (13.06): Yes, Jon. It turns out that the delete key is sort of
mapped differently in different Mac keyboards. In some laptops you can
click on an object and do Function + Delete, and in some desktops you
have to use the special "Del" key that is in the little section between
the alphanumberical keyboard and the numeric keyboard. Let me know it
that does not work. @: Message 43: To whole message | | | |
|
| 46 |
| JohannMF, 13:46 (13.06): Usually, below Insert, and before "End" @: Message 45: Del" | | | |

| | | | Gene,
13:47 (13.06): I know it's not started yet, Suz! just practicing my
typing. Incidentally, I won't be able to stay around for the whole
thing. (Another project has things I must do). | |
|
| 50 |
JohannMF,
13:50 (13.06): Great! BTW, feel free to erase my instructions for
latecomers, since they are recorded in the history of the whiteboard
and you can refer to them in a message if you want. @: Message 48: To whole message | | | | |
|
| 51 |
| | | | | zebroid, 13:48 (13.06): You're right Gene about this. I am having a ball and can't wait to try and use it in real time. |
|
| 52 |
| JohannMF,
13:52 (13.06): Jon, do you know how to make references (links) between
messages and from messages to the whiteboard? That can be very handy
specially for the "presenter" so if you need any help, let me know @: Message 51: To whole message | | | | |
|
| 53 |
| | | | | zebroid, 13:50 (13.06): No. How about a quick lesson. |
|
| 54 |
| JohannMF,
13:54 (13.06): Sure! To linke one message to another, simply click on
the message you want to link to (respond, comment, etc) and you will
see a blue arrow linking the Message textfield with that message @: Message 53: To whole message | | | | |
|
| 55 |
| | | | Gene,
13:52 (13.06): Oops, Return doesn't work the way I wanted--submits and
doesn't start a new paragraph. Well my new paragraph was to ask who
will be the note taker. I hope something is put up so that others (like
me) can use to learn what happened and join in the discussion later. | |
|
| 56 |
JohannMF,
13:55 (13.06): To link a new message with a point on the whiteboard,
use the "Reference" button on the toolbar on top of the whiteboard are.
Click on it, then click on the whitebaord and drag your mouse to open a
"highlight area" like this one. IT will be automatically connected to
your new message. @:  | | | | |
|
| 57 |
| | | | | zebroid, 13:53 (13.06): Neat! double clicking changes it if you make a mistake which I did the first time!!!! @: Message 55: To whole message |
|
| 58 |
| JohannMF, 13:56 (13.06): That's true, Gene. Ctrl + Return starts a new paragraph. Retursns, submits your message. @: Message 55: Return doesn't work the way I wanted--submits and doesn't | | | | |
|
| 59 |
| JohannMF,
13:57 (13.06): Exactely! Now you know more than I do! ;-) BTW, Esc
clears all references from a new message but it also deltes the message
you are typing as I said before @: Message 57: double clicking | | | | |

| JohannMF,
13:59 (13.06): I will ask Annie when he joins us, Gene. This

can summarize it. @: Message 55: note taker. | | | | | |

| | | | | zebroid, 14:03 (13.06): Suzanne, you've done a lot with polyhedra. Do you see Cabri 3D as being able to enhance wha tyou do? |
|
| 70 |
| | Suzanne,
14:04 (13.06): Yes! From the little that I've been exploring (very
little up to now I admit) I think it looks very cool. | | | |
|
| 71 |
| | Suzanne, 14:04 (13.06): From your experience, Jon, what age level is it appropriate for? | | | |
|
| 72 |
| | | | Gene,
14:04 (13.06): While we're waiting for Suz let me mention that I once
tried to get a 3D drawing program along with the Geometry Center. Never
got funded. | |
|
| 73 |
| | Suzanne,
14:05 (13.06): I ask because I just cataloged it in Math Tools and I'm
wondering if I checked the appropriate courses/topics. | | | |
|

| | | | | | steve, 14:04 (13.06): joins the room |
|
| 75 |
| | | | | zebroid,
14:06 (13.06): I'm planningto use it in my 9th grade geometry course
and in a linear algebra coure we teach to stduedents who have done the
BC calculus. There is a ton of interesting problems yo ucan attack
using this vectors anda computeralgebra system. I have found the vector
capabilities of the softwarefascinating. | |
|
| 76 |
| | Suzanne, 14:07 (13.06): I just put the URL on the WhiteBoard | | | | |
|
| 77 |
| | | | Gene, 14:07 (13.06): How about a bit of a whiteboard tour, Jon or Johann? I'd like to see how this integrates. | | |
|
| 78 |
| | Suzanne,
14:08 (13.06): One thing I'll be sure to do once we finish this is post
to Math Tools and ask for help cataloging Cabri 3D then people of
different levels can help me and I'll edit what I put originally | | | | |
|
| 79 |
| JohannMF,
14:10 (13.06): Integrates with Cabri 3D? Unfortunately it does not. It
would be really wonderful if you could have this kind of chat with
Cabri 3D instead of the Whiteboard... that is something we are
exploring. @: Message 77: integrates | | | | | |
|
| 80 |
| | | Bethany,
14:09 (13.06): Any idea on what specs that cabri 3D requires? Cabri
seems really jumpy on my machine, particularly the rotate feature... | | | |
|
| 81 |
| | | | | zebroid, 14:09 (13.06): Johann, lead us. | |
|
| 82 |
| JohannMF, 14:12 (13.06): O.K. I'll just give you a quick tour so that you can concentrate on Cabri 3D. @: Message 81: Johann, lead us. | | | | | |
|
| 83 |
| | | | | zebroid,
14:10 (13.06): Good question. I've use dit on ag4 powerbook and a G-5
desk top and it works fine. The rotation tool takes a while to ge t
used to. Did you try changing the view ratio? @: Message 80: To whole message | |
|
| 84 |
JohannMF,
14:13 (13.06): The Whiteboard works like pretty much any object drawing
program but, of course, it is shared so everything you do is
broadcasted to all chat participants. The cool thing is that you can
reference things in the whitebaord (like the URL) from your chat
messages. @:  | | | | | |
|
| 85 |
| JohannMF,
14:15 (13.06): You can also link your new message to another message
just to make it clear what you are responding to. To do that just
double click on the message you want to link when writing your new
message. I think that is pretty much all that you probably need for
this kind of session. @: Message 81: To whole message | | | | | |

2. Click on your image and drag and a box appears with a blue line connecting to the message box
3. Type your message and when you press return it connects to it. | | | | | |
|

|
| 121 |
| JohannMF,
14:41 (13.06): Very good idea. To do that, you can use the icon on the
right of the elipse tool. Click on it, click on the whiteboard and then
create a yellow note on the Whitebaord. @: Message 120: atext box | | | | | |
|
| 122 |
| | Suzanne,
14:40 (13.06): 1. I selected the tool at the very right side of the top
navbar and saw that "cube" was one of the options.
2. Once I selected it I just followed the prompts.
3. What I don't know is if it really is a cube. How do I measure the
edgelengths or angles or anything to confirm that each face is a
square? @:  | | | | |
|
| 123 |
| | | | zebroid, 14:41 (13.06): Cabri has no measurement tools per se but you could do it indirectly using coordinates | | |

| | Suzanne,
15:01 (13.06): Annie can color her faces differently because she
constructed hers. Mine is all one color because I used the "cube"
option from the menu. | | | | |
|
| 138 |
| | | | | | Annie,
15:02 (13.06): Jon, how similar is this to regular Cabri? I'm assuming
that if you're comfortable with that, this is a piece of cake. (Being a
Sketchpad person and a very non-regular user of Cabri, I'm finding
things clunky and frustrating at times, when a particular tool, like
the circle, won't do what it just did a minute ago.) |

Remember the basic metaphor is different. In GSP you choose an object

the opposite. @: Message 138: To whole message | | |

| | | | | | Annie,
15:07 (13.06): right, I've accepted that metaphor thing and don't
usually run into problems. But here, for example, I selected the circle
tool, clicked on one point and then another (thinking center-radius),
and then told it which plane. That worked great. But when I tried it
later, it wanted to instead do a circle through three points. Maybe I
had something else selected in some menu or something, but it was
confusing (and I had to come up with another way to do it). @: Message 140: To whole message | |
|
| 145 |
| | | | zebroid, 15:08 (13.06): Try making a plne out of the three points and then make your circle. @: Message 144: To whole message | | | |
|
| 146 |
| | | | zebroid, 15:09 (13.06): Should be plane. @: Message 145: plne | | | |
|
| 147 |
| | | | | | Annie,
15:10 (13.06): I actually already had a plane in which I could put the
circle, but it wouldn't let me do it. It just wanted a third point.
I'll play with it again, but for now I'll briefly rest on the laurels
of having constructed an honest to goodness cube! @: Message 145: To whole message | |

there a way to have a "solid" cube, with all six faces created, and
make the side translucent so that you can actually see the tetrahedron
inside? I've tried making the faces of the cube thin or very thin, but
all I can see of the tetrahedron is the edges. |

|
| 181 |
| | | Bethany,
15:56 (13.06): Honestly, I gave up. I've just been struggling too much
with trying to get the positioning correct (using the rotate tool) so I
can see what I'm doing... I don't know if its me, my computer, or the
download version. | | | | | |
|
| 182 |
| | Suzanne,
15:57 (13.06): Annie and I are both using the full version (not the

too. | | | | | | |
|
| 183 |
| | | | zebroid,
15:58 (13.06): We already do a lot with polyhedra and I will use it
when we study duals and the semi-regulars. Latr in the year when we
focus on a more traditional approach to triangle geometry I will use it
to study those properties of tetrahedra that are similar to those for
triangles: special centers, special circles and spheres, etc. . | | | | |
|
| 184 |
| | | | zebroid,
15:59 (13.06): You're right about the rotate tool. It can be tough and
you can get lost easily. I found that if I started with a small figure
and used the View feature I had better luck. What kind of computer are
you using? | | | | |

16:20 (13.06): Isn't that what happens when you poke out each face of
the cube, constructing a pyramid on each face? Only I guess I poked out
so much that adjacent pyramids merged, to give rhombi. I guess that
would be the only time that the dual would be as "clean" as the
truncated cube. @: Message 211: To whole message |

but I'm not yet convinced of utility for all (after over 12 hours spent
with Geometer's Sketchpad, some of my gifted students are still
relatively unable to use it for conjecturing, much less proving). |
|
| 223 |
| | | | | | Annie,
16:28 (13.06): I think it's pretty slick, just because it actually does
work, and if you are at all familiar with dynamic geometry, it's
doable. But it's clunky, and things are sometimes hard to see (which is
almost always true when doing 3d geometry in 2d, of course). @: Message 220: To whole message | | |

| | Suzanne, 16:52 (13.06): By the way, EVERYONE who was here today should give the tool a rating, perhaps write a comment? | | | | | |

| | Suzanne, 16:57 (13.06): I think that some of the memory issues and all could be good for short comments after you've rated. @:  | | | | |

17:00 (13.06): An on-line session dedicated to learning more about
Cabri 3D was held today. Taking part were members of the Math Forum
staff as well as participants in the Forum's MathTools Fest last
summer. Participants used the software to first construct regular
polyhedra and then perform a variety of transformations on them. If you
are interested in finding out more you can download a free demo from
http://www.chartwellyorke.com/cabri3d/cabri3d.html. In additon a
collection of video tutorials and some introductory exercises can be
found at http://ww.zebragraph.com/cabri tutorial.html | | |

| | | | | Annie, 17:01 (13.06): Point out the cabri.html page, at least. @: Message 271: To whole message | |

| | Suzanne,
17:02 (13.06): Is there a second paragraph that you could add that
might get some of the participants to respond or ask questions or ? | | | | |
|
| 274 |
| | Suzanne, 17:02 (13.06): Also, I'm thinking we might want to point out that the participants were from the Remote Tool Fest '05? | | | | |

| | | | zebroid, 17:02 (13.06): Which page do you mean? @: Message 272: To whole message | | |

JohannMF,
17:09 (13.06): BTW Annie you can include the screenshot of the
whiteboard by referencing the image included in the transcript of this
session. It looks really cool. @:  | | | | | |
|
| 279 |
| | | | | Annie,
17:08 (13.06): I think you can leave out the links to your stuff and to
the chartwellyork site by instead pointing to our cabri.html page. That
way people will make more connections with the work we did anyway. | |
