ROOM429: A Little PC Classroom Remodeling after XMAS Break! (The optimal PC Classroom setup)

OK, I finally broke down and moved my whole room around ... again!

I moved the front two rows about one foot forward. Also, I staggered the back row so as to make room in the rear center part of the room for a Teacher Station. Take a look at the pixs below! Its almost a PC Podium/SmartBoard setup now. All I need for a PC Podium is some extra audio/video/internet cables to easily hook up a laptop. In addition, I wouldn't mind another PC in the Teacher Center so I can have one running WIndows all day and the other Linux.

Size Matters!

Wow, now the story is my cluster is moving with me and I have to picka room. I was told I'd be going to Room 622 but I complained that is was too small. Room 429 is 34 ft x 25 ft. Room 622 is 28 ft x 26 ft. So, I was told to measure out Rooms 513, 615, 616 and 619 to pick the largest of these. However, these rooms are all 27 ft x 23 ft!

So, Room 622 is the least of all evils. If I had my druthers I'd stay in Room 429. However, I happened to wander into Room 620 which is not an English room, so its off limits. Room 620 looks like a one-time Chemistry Lab, but it only has desks, do apparatus and its 30 ft x 28 ft! This room would be OK. Lets see if i can persuade the powers-that-be to let me have it.
IDK, how this move is going to happen at all. The logistics are phenomenal and the funding reduculous.... Maybe it won't happen after all!

The Tech Dept goes postal!

Wow, the entire tech dept descended upon me the other day! All I did was innocently dispatch an email to the tech dept that I needed an ethernet cable extended as I moved my PCs around a bit.

Well, don't ya know, all hell broke loose! First the head of the tech dept emails my chairperson asking what the heck I was doing. Then my chair comes to my PC Classroom asking who the heck I was to do such a thing? Then the assistant principal for tech catches me in the hallway and calls me on the carpet. Finally, the new superintendent for curriculum and tech paid me a visit wondering what I was up to!

I proceeded to show each of these worthies that all I did was move the PC tables toward the front of the room by one measly foot! The only problem was I couldn't move the printers out of the way sufficiently as the ethernet cables were too short. The reason I did all this was to make room for my desk in the back of the room by the teachers' PC. I had to move all my stuff back there as my wireless mic failed so I had to use a standard wired PC mic.

BTW, I was the one who brought PCs to the school for the first time in the 80s. My PC Classroom is used as a model for all the other labs in the district now. There was no tech dept then. I was the only tech guy from 1984 to 1996.

Well, I don't mind telling you that I was just flabergasted!

Size Matters!

Wow, now it looks like my cluster is moving with me to Room 622! The problem with this scenario is that my current room is 34ft x 26ft, while this new room is only 28ft x 25ft. So, of course, I complained, and was told to pick from 613, 615, 616 or 619. However, these rooms are 28ft x 24ft or smaller!

If I had my druthers, I'd stay right where I am. The logistics of this move are so phenomenal, not to mention the tremendous expense, that maybe it just won't happen.... I can dream, can't I?

Another possiblilty is Room 620. Now, this is not an English room, it looks like Earth Science, so I guess its off limits. But, if I could persuade the powers-that-be to let me have it, its a bit bigger so not a bad choice (28ft x 30ft).

Regardless, to fit in a 30ft or 28ft space as opposed to a 34ft space will necessitate new furniture. Right now I have 2.5 ft x 3.5 ft desks. Half of each desk is taken up by the student's "PC desktop," the other half is the student's "wooden desktop." I have these desks arranged in 3 rows of 8 desks. This arrangement fits lengthwise in the 34ft space I currently have in Room 429 leaving a nice 3-4 ft aisle down the middle. We won't have this luxury in any of the new rooms. Maybe 2ft x 3ft desks will work better?

Hand-me-down lab?

Wow, I cannot tell you how upset this move is making me....

It's as if the last 25 years of work that I have done in Room 429 is just to be thrown out the window. Now I'm told that I'm not to have a new lab in Room 622 after all. I'm to go into Room 612, the current English Dept Writing Lab! If memory serves, this lab is on the first floor and is really small without even any room for a projector and consists of several computers I used to have in Room 429 years ago - my own had-me-downs!! What at a huge step backwards obviating many innovations I've brought to the Baldwin school district in general and to my students in particular!!!

Best case scenario is that I don't move at all. If I stay in Room 429 and the rest of the Math dept moves to the 600 wing, so be it, I'll be an island onto myself in a sea of Foreign Language classes (Math is replacing English, but English is replacing Foreign Language)! Room 429 is already the ideal Computer Science/Calculus Research Lab! It isn't just the computers, which are state of the art by the way (25 dualcore 2GHz 64-bit AMD Athlons amounting to a 50 core superCluster or super computer running at 100GHz with 1000GB storage and gigaBit switched Ethernet) . Its the infrastructure too:

(1) I'm running three Linux servers from there (ftp, ssh and apache soon to be SAGE; centauri, colossus and guardian).
(2) There's an enourmos amount of power going into that room for PCs, printers, projectors, speakers, mics and AC.
(3) I've setup a Windows Smartboard as well as a Linux Smartboard after many hours of research and work on my part these past three years alone.
(4) Don't forget, there's three networks in there too for Windows, Linux and the superCluster.

Next best case would be moving to Room 622 with all the hardware listed above moving with me. However, that's a huge undertaking, requiring a large commitment of man-hours and funding. Further, you know that there will be millions of bugs after a move like that severely limiting instructional time after the move.

Third best case is moving to Room 622 and designing a whole new lab from scratch. Wow, imagine the man-hours and funding involved for that! Also, don't forget that Room 622 only has room for 18 students as opposed to the current 24 stations (computer desktop + wooden desktop) in Room 429.

Clearly, the worst case scenario is dumping me into a writing lab! How will I run Linux and java to teach my AP Computer Science classes? How will I run all the superCluster apps for myComputing Independent Study class?? How will we implement SAGE for the new Calculus Research Lab??? How will I display and record my Smartboard lessons in AP Calculus BC????

As you can see, moving the Computer Science/Calculus Research/SmartBoard/superCluster Lab is a really, really bad idea! I've been working to perfect this lab since the 1980s. I've made several hardware/firmware/software/infrastructure/curricular innovations over the course of these past, nearly, three decades that have inspired computer labs all over the district. Said innovations, built into Room 429, will be near to impossible to move or replicate....

Remodeling the PC Classroom?

OK, I started thinking about a new PC Classroom. So, even if we don't move the PC Classroom from room 429 to room 622, I think we should do a little remodeling in 429 anyway.

The way I teach in 429, I really don't need a teacher's desk in the front of the room. I usually teach from the back of the room using simply a keyboard when teaching programming or the Smart Airliner when teaching math. This way I can see what everyone is doing so as to make sure everyone is on task.

So, why not create a "teacher center" in the back of the room? In other words, move the teacher's desk to the back with the teacher PC. That way, I don't have to take up a student's station when using the Smart Airliner and I have more space for all my books and notes while teaching.

Also, we could use a 2nd teacher PC in this new "teacher center" so one PC runs Linux only and the other PC runs Windows only all day. Switching back and forth is very time consuming especially if another teacher needs the classroom the following period. We would also need at least a video switch, if not a KVM switch that allows for just one keyboard, one mouse and one monitor controling both PCs, to easily change the PC Projector's source from the Linux PC to the Windows PC.

Now, the students' desks can move forward so there's room for this new "teacher center" in the back of the room and the students can better see the Projector Screen. To further facilitate students' view from the back and sides of the room, I think we could also use flat screen monitors.

Last, but not least, we really need the new Projector Mount ASAP for the new PC Projector we got from http://www.donorschoose.org since we are currently going blind trying to see what's on the Projector Screen now!

... and the beat goes on!

Wow, I just found out where they plan to move my pcLab/classRoom. We are moving from room 429 to room 622 in order to be closer to the science department so as to improve collaboration! BTW, we already collaborate plenty.

This move is a huge mistake, however. I've been in room 429 since 1984 and I've been perfecting it all that time. Room 429 is great the way it is. If The-Powers-That-Be decide to move my existing hardware, software, firmware, linux LAN, linux cluster, windows LAN, ftp server, ssh server and apache server you know there's going to be a ton of debugging to do after the move. Nothing will work right for months adversely affecting the amount of instruction time available.
On the other hand, if we build a new lab from scratch, we are still looking at a lot of manhours before, during and after the move. I didn't even mention the expense of all new hardware...
A bigger problem still, is the fact that room 429 is about 22 ft x 32 ft. The new room, 622, is only 22ft by 25ft or so. How will we fit all 24 student stations in the new room? If we move to the smaller room, we would have to sacrifice upwards of 6 student stations!

BTW, please realize that room 429 is not just a resource lab used once in a while for its PCs. Room 429 is used everyday as a classroom too. As such, every one of the 24 students has a "PC desktop" and an old-fashioned "Wooden desktop." The wooden desktop is necessary for taking notes, writing drafts, taking tests, etc. The PC desktop is necessary when the students are programming.

My AP Computer Science students have always used both desktops every period, every day. My AP Calculus students traditionally only used the wooden desktops, but they are starting to use the PC desktop more and more as we discover more scientific computing and computer algebra system applications! Origianlly, I moved my AP Calculus students into this pcLab/classRoom some years ago as it was the only room where I could use the Smart Airliner Slate (Wacom PC Tablet that works with Smart Notebook like a Smartboard) to present and record all my lessons.

Current Room 429:
SS_SS_SS_SS_         _SS_SS_SS_SS
SS_SS_SS_SS_    x    _SS_SS_SS_SS
SS_SS_SS_SS_         _SS_SS_SS_SS
                        TS
Propsed Room 622:
SS_SS_SS_         _SS_SS_SS
SS_SS_SS_    x   _SS_SS_SS
SS_SS_SS_         _SS_SS_SS
             TS1     TS2
SS = Student Station/PC desktop
_ = wooden desktop
x = ceiling mounted projector
TS = Teacher Station/PC desktop

BTW, the new room has 2 teacher stations proposed. One will run Linux all day and the other will run Windows all day. This way, we don't have to reboot the teacher station every period when teachers need to switch from Linux to Windows and back again!
