Sam pointed out that my software replaced the podcast with the pdf, leaving me with 2 copies of the same thing. DOH!
So I spent a week trying to get Edublogs to allow the upload. No success, and lots and lots of failure!
So, here it is, linked from Box.net. Operations with numbers MP3
Which left me with a week of trying services to figure out a way to share files like this. I settled on Box.net, simply because it was easy. The free service gives you 1 Gig to share. That is a lot of space, unless you are sharing a ton of MP3 files. We will have to see if I need to upgrade or just get my own server space. I am collecting lots of images, video, and sound, and it is difficult to share this.
So what are the technology needs of the modern teacher?
Let’s look at Dan. He has HUGE amounts of video available on his site, as well as the new geometry section, constant images, and text. How much of that is required to be accessible to the teacher every day?
And if your school district is like mine, the firewalls and filtering they have set up keep the teachers out of things like Box.net, but not the learners.
I scanned my hard drive today, and I have over 10 gigs of data on it. This is just my laptop that I only use for school and my personal classes I am taking. No pictures of family and friends, no CD’s ripped just for fun, only professional stuff on this computer.
10 gigs.
That is a lot of files that I use, have used, or will use. I carry my laptop with me everywhere, because I can not depend on an internet connection at school (personal computers are not allowed to connect to the district system) and useful sites like Box.net are blocked because of “file sharing”.
It would be so much easier to just upload the whole hard drive to a secure, yet accessible site, and just use the files from that location.
Should teachers have to take on the burden of cost for this too? After all, we already purchase paper, pencils, and other supplies for our rooms. Heck, 15 seconds with Quicken tells me that I have already spent $351.91 this year alone. The year is not over, not by a long shot.
Do we need to start bearing the burden of server space and web hosting too? It can get expensive, and yet the monthly charges for a service like Box.net (I just signed up for the free service though) also can get pricey. 5 Gigs for $95.40 a year ($7.95 per month) or 15 gigs for $239.40 per year ($19.99 per month).
For those prices a domain name from GoDaddy.com is only $8.99 and I could get an unlimited account for only $170.88 per year ($14.24 if you sign up for a year, it is only $12.74 per month if you sign up for 3 years!)
At what point do teacher stop being just classroom entities and start becoming producers of content. I think we NEED to be already there. And if we are, is sharing with just our learners sufficient? Dan already has shown us how much can be done. How willing are WE to step up to the plate and start sharing what we do in the classroom with each other?
And if we do share, we must bear the burden of cost on our selves. I know my district won’t pay for it (although shouldn’t they if it helps me, my learners, and my school?)

I told Sam that I would post this, so here is a sample of the podcast of my lecture. It is rough and unedited. I am torn between editing them right now. It takes me about 3 to 5 minutes to post these on my school’s Edline website for the learners. If I edited and took out the “so” (do I really say that 200 times a class, I must, it there on the recording) and the “okay’s” then it would take much much longer.
I am going for information to learners with this. So far I have had at least one person PER day tell me they have listened to it and it has helped. That is enough for me to continue all year.
If I had to edit, then it would take so much time that I probably would not do it, honestly.
The PDF does not show the steps that I used, nor the animations for the Commutative property. I refuse to use animations unless it has a purpose. When I draw arrows, then I use a wipe that goes from the beginning to the arrow.
For the Commutative property, I used a rotation that had (a + b) rotating around the “+”. That gets the idea of movement across to the learner. I ‘think’ it helped.

The first part of technology that I am using is my laptop. It is my personal laptop, and I have a cable lock for it just to keep it from wondering away when I am not looking. It is nothing special, a Toshiba Satellite, 12.5 inch screen, 3 years old. I use OpenOffice on it exclusively (mainly because I purchased it when I was in grad school and broke.) I have had great luck with OpenOffice, and I make my daily powerpoints for Alg 3-4 with it. Very easy to use, and I have constructed some simple graphics on it to make my points. I am running into the barriers of the software though, and I will be installing the 2007 version of Office I bought under the “ultimate steal” campaign they have. [$60 for the full Ultimate version of Office!!!].
Okay, laptop connected to the projector on the second video cable. I also purchased an Elmo, HV-110xg off of eBay over the Summer. total cost including shipping was $120. Totally worth it. This shares a video cable, so I have to swap devices. Takes about 3 seconds.
So the laptop is running the presentation that I have carefully built to teach the lesson. I turn the presentation to a pdf, and upload the pdf to Edline (our district’s online software). If someone has a question not addressed in the presentation, I can switch devices to the Smart Panel using the projector’s remote and do the problems and address the questions on the whiteboard. More importantly, I can have the learners come to the board and work the problems on the white board. I use a remote control for the presentation, so I am teaching from the back and sides of the room, not the front. I am not tied down anywhere.
I also have an iPod, 80 gig, that is record my lectures on. Very powerful to upload the presentation, and the MP3 to Edline. I have had several learners tell me they listened to the MP3, and looked at the presentation, and were able to figure out the assignment.
The iPod works terrifically. The iTalk I use retails for $50, but on eBay I snagged one for $12.00 including shipping. Plug it into the iPod, hit record voice memo on “low” quality, drop it in my shirt pocket, and I get stereo recording of what I am saying. It will pick up a learner if I am close to them, but otherwise not.
Sync the iPod to my laptop during break, import it into Audacity with the LAME MP3 encoder installed and export the .wav file as an .mp3 file. Reduces file size significantly, and makes for faster uploads and downloads. More importantly, it can now be listened to on any device in existence today, even cell phones. Total time is around 3 minutes, total software cost = ZERO dollars.
I can also play video from the iPod and show it over the projector. Using the Apple Component AV Cable I can connect my iPod to the projector (remember that 5 wire cable I ran?) (Retail cost = $50) Now I can show the YouTube videos that my district has blocked on my iPod. Some very great videos on YouTube, if you are selective. I can also play music over the speakers I installed. That is nice for beginning of class, breaks, etc.
I have also been using Geogebra to model mathematics over the projector. More importantly, I have been asking the learners to bring in photos on their cell phones and use those pictures to model the mathematics. Now the cell phones actually have some valid use in class! When I purchased a SD card for my cell phone, it came with one of these adaptors, so I didn’t have to purchase anything else to read the little cards that they have in their cell phones.
Whew. That is a lot, but it is not hard once I got started and did it. It took three weeks to get a system down though. I spent all summer trying to do this, and then that, and then this again to make sure it would work. The effort is worth it though.
I recorded a class, synced the recording to my laptop, converted it to an MP3, uploaded to Edline, and let the class listen to it, all in the span of 3 minutes.
They ask me if I am recording and remind me now. That is successful. They tell me they listened to it over the weekend. That is successful.
