Fare Thee Well, Summer Session II, Part 2: The YouTubes!

Holy cow, Summer Session II is over tonight? We have covered 5 whole weeks of Calculus already? Actuallly, what I should be asking is: "How the heck did we cram Calculus I into 5 weeks?" 

Well, I already blogged about the first week, 

Also, I had previously blogged about my tech setup:

What follows are the YouTubes I used to break up the class routine! I usually started each class with a review of the homework, then I showed one of the following "educational" YouTubes and then I started the actual lesson.


Week 1
201 = mathematicious
202 = I will derive
203 = calculus rhapsody

Week 2
301 = calculus summer
302 = theorem night
303 = sleigh bells

Week 3
401 = hopper1
402 = hopper2
403 = hopper+letterman

Week 4
501 = Lehrer – new math
502 = Lehrer – periodic tablex2 videos

and
601 = Lehrer – lobachevsky

Week 5
602 = archimedes
701 = pauschx2 videos
1101 = escalantex3 videos

HTH, I hope you enjoyed Calculus I this summer!

Welcome to Summer Session II!

Wow, is it really Summer Session II 2011 at Nassau Community College already? I am privileged to have a section of 25 eager new students in NCC Math 122, Harvard Calculus I. Welcome!

We just finished our first week. We flew by Chapter 2 on differentiation in the 5th edition of Deborah Hughes-Hallett's wonderful reformed text, Calculus Single Variable. The first thing I did (after making seating assignments, discussing the syllabus and collecting bio sheets) was to create an http://www.edmodo.com group just for this class and showed my new students how to join and spoke to the benefits of joining. Of course, I had to show them http://shadowfax.blogspot.com and http://www.youtube.com/calcpage2009 and I began the class with a filk from Youtube (Mathematicious).


Here's some of the first uploads I made to Edmodo for this group. Lesson 201 was about limits and finding the derivative at a point using convergence tables. This document is the syllabus for this summer. In other words, all the legalize and rules of the road! Also, all the assignments are listed as a pacing guide.

This pdf is a copy of all my SmartNotes for Chapter 2 Lesson 1. As you can see, I started talking about solving problems Graphically, Numercally, Analytically or Wordily!

This YouTube is a ScreenCast of the first class. 




Lesson 202 was about finding derivative functions analytically. In this, the second class, I realized that I had never formally stated the definition of continuity at a point, what I call the "Cuban Theorem." So, after stating this definition, I had to start that class with "Theorem Night!" 

See more screencasts: http://www.patreon.com/calcpage2020


Yesterday's class, Lesson 203, was mostly about Newton's Method and writing a program to do Newton's Method in TI-83/84 BASIC (today was our first test). BTW, I had to start this class with "I Will Derive!" I think Monday we'll view "Calculus Rhapsody."



HTH, I hope you enjoyed our intro to Calculus!

Taking the show on the road!

I am fortunate enough to have secured a PC Lab/Classroom for this summer at NCC. So, I brought my laptop and tablet to do all my SmartBoarding! What follows are pictures from Room B115 that show my tech setup! As you will see, I pipe everything through my laptop that is, in turn, attached directly to a PC Projector in the front of the room. I had to sit in the front of the room in order to use my bluetooth tablet to control the works! I had to sit in an odd position such that if I turned my head to the left I could see my students and if I turned my head to the right I could see what I was writing on the PC Projector! This was the only configuration that worked. The room is too skinny and deep. I tried not to seat anyone in the back row as they would have a hard time seeing the "SmartBoard." In fact, it's not a SmartBoard. There is some sort of 3Comm infrared pen interactive whiteboard, but they don't let anyone use the pens. As a result, there is a swing arm projector on the board, but its really just a marker board. I don't even get a Projection Screen! Also, the PC Projector is so close to the board, that the output is very small. The setup in this room is far from optimal. However, as you will see, I tried to improve things with my laptop and tablet, aka my portable smartboard!

















HTH, I hope you enjoyed seeing how I setup my portable SmartBoard!

Screencasting 101: "To be or not to be?"


I've been screen-casting and smart-boarding in various mathematics and computer science classes for over 5 years now. So, I thought it would be beneficial to some of you who haven't had that much experience with all this technology if I were to summarize some of what I've learned though out all my trials and tribulations!

(1) To Smarttech or not to Smarttech?
There are alternatives after all! Many teachers swear by their Promethean or Interwrite products. Even 3Comm has an interactive whiteboard based on infrared pens! I did all my so called smart boarding for the longest time without any Smarttech products at all! I use all Smarttech now as my High School finally upgraded all our classrooms. If I had my druthers, I'd use a Tablet PC such as the Lenovo X201T connected remotely to another PC with a PC Projector via RDP. So, "To Smarttech or not to Smarttech?" Not!

(2) To Smartboard or not to Smartboard?
Again, there are other options here. When I started out smart-boarding for my students, I used a Wacom Graphire 6x8 Bluetooth remote mouse. I call it a remote mouse rather than a tablet as its not like today's tablets. The Graphire was a great solution that would take over the function of your mouse from anywhere in the room typically used by graphic artists to make freehand illustrations. The one drawback was that you could not see what was written on the tablet itself. It had a magnetic sensitive 6" x 8" (capacitive not resistive) writing surface and a magnetic pen. So, I had to crane my neck to see what I wrote on the PC Projection Screen way across the room! One good thing about this setup was that all you needed was a PC Projector, no Smart Board need apply! Also, I could hover the pen over the writing surface moving the mouse pointer around on the screen without writing anything so I could use the mouse pointer as if it were a laser pointer! So, "To Smartboard or not to Smartboard?" Not!

(3) To Smart Notebook or not to Smart Notebook?
I've used other pen apps in the past as well. For example, I used to use Xournal all the time. Since my school recently upgraded every classroom to Smarttech, I've been using Smart Notebook a lot. However, I just use Smart Notebook to record what I write in class as a pdf. I even installed Smart Notebook in Linux to record my Computer Science notes! However, I do not use Smart Notebook to prepare lessons ahead of time. I refuse to waste hours of prep time using all the bells and whistles in Smart Notebook to make every class into a PowerPoint presentation! Anyway, most of the Smart Notebook features seem to me to be designed more for Elementary School or Junior High, not High School or College. So, "To Smart Notebook or not to Smart Notebook?" Not!

(4) To Smart Record or not to Smart Record?
Whenever I am teaching a new topic, I also record my desktop as a video, usually in *.mp4 format, for students to review as needed. All I add to the mix is a wireless 75Mhz Lapel Mic (from Radio Shack) to record all I say as I write. I love http://screencast-o-matic.com as it encodes videos very quickly. Also, if you don't have time to encode right away, screencast-o-matic stores a cookie on your PC that points to a temporary file stored on their website that you can encode later. The only drawback to screencast-o-matic is that you need an internet connection the entire time you are recording. Also, you are limited to 1 hour and that's if you subscribe as a "Power User" for $12 per year. If you want to record offline, there's other solutions. In Smart Notebook for Windows, you can use Smart Recorder which records as lomg as you want. This application encodes quickly if you use the *.avi format, but these files tend to be huge! You can set Smart Recorder to encode *.mp4 files which are smaller but take a long time to encode! In Linux many users like RecordMyDesktop as it has a nice GUI. I have had better results with ffmpeg, however. So, "To Smart Record or not to Smart Record?" Not!

(5) To GC or not to GC?
I am convince that using TI-81s, 82s, 83s, 84s, 85s, 86s, 89s and 92s constantly for the last 20 years or so has contributed to my needing reading glasses! So, I never use an actual hand-held Graphing Calculator, I use an emulator such as VTI on my SmartBoard or a Computer Algebra System such as http://www.sagemath.org So, "To GC or not to GC?" Not!

(6) To Windows or not to Windows?
As you know, "I don't do Windows, and neither does my Maid!" So, most of the hardware and software solutions I recommend above work well in Windows and Linux! I use a Smart Board or Tablet with Smart Notebook or Xournal and Screencast-o-matic or ffmpeg in Linux: 
ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 800x600 -i :0.0 test.mpg 
I find that the 32bit Ubuntu Desktop 10.04 LTS works quite well and is easily customizable to accommodate all the above! So, "To Windows or not to Windows?" Not!


(7) To Tablet or not to Tablet?
I've used a Smart Airliner Slate for years now. Its really a relabeled Wacom Graphire 6x8 Tablet that's more commonly used by artists to make sketches on a computer. It has a magnetic pen and a capacitive surface but you can't see what you write on it directly. You need to look at the remote desktop connected via Bluetooth or a PC Projection. I've used this setup instead of a SmartBoard for my ScreenCasts. I now have a SmartBoard, so I only use it on the road at conferences or at the local college. The picture above is of a Tablet PC from Lenovo model X220T. It converts to a regular ThinkPad laptop and back to a Tablet PC in a flash. If I had my way, I'd be using this device instead of the Airliner or the SmartBoard! Take a look at this rock-solid update to the X201T, http://www.trustedreviews.com/Lenovo-ThinkPad-X220-Tablet--X220T-_Laptop_review

So, it seems that I've come down on the side of "Not!" for all of the above, but that's really just my personal preference! Perhaps, now you have some food for thought?

I hope you found all these screen-casting tips useful! What do ya think?

SmartBoard on Linux? They said it could not be done!

I finally broke down and ran Linux on my SmartBoard in every class for the the past couple of weeks!
(1) bluetooth Tablet (Wacom Graphire 6x8 with capacitive surface)
(2) wireless Mic (Radio Shack 75Mhz Lapel Mic)
(3) pen app (xournal)
(4) SAGE (keyboard intensive CAS)
(5) http://screencast-o-matic.com/ (online service)

First, I got my old setup (as listed above) working with the Smart Airliner Slate. Actually, its a bluetooth remote mouse from Wacom called the Graphire 6x8. Its the kind of tablet whereby you don't see what you're writing on the tablet itself (please see my donorschoose project). You get used to craning your neck and watching the PC Monitor or the PC Projection Screen or the SmartBoard clear accross the room to see what you've written.... 

Anyway, I've used the Graphire for years to write my Smartnotes on the fly in class and to make live Screen-casts of my classes. Its a nice little tablet with a 10" diagonal writing area. Also, it has a capacitive surface so I can hover the magnetic pen over the tablet without writing so that the students can see me highlight something on the screen as I circle over it. So, my YouTube Recording Studio works fine. BTW, xournal is a nice java *.jar app so its cross-platform. It can save to *.pdf and has nice paper backgrounds such as graph paper. It also recognizes geometric figures, so if I draw a circle or triangle, xounal redraws it for me nice and neat! I use xournal because of these features and because installing Smart Notebook takes for ever. Why install Smart Notebook if I only use it as a pan app?

However, one hiccup was that the bluetooth mouse sensutivity is way too high even when I set it to the lowest possible setting, so you have to write really, really slowly.... Another little SNAFU is that the SmartBoard will go to sleep at times. The surface will stop reacting to the pen (the green light goes red). This may be due to the fact that I have a very long USB line (extended via ethernet) from my Teacher station in the back of the room to the SmartBoard in the front? I find that the only way to counter act this problem is to start using the regular keyboard and mouse for a few minutes and then the SmartBoard starts to function normally. One time I had to logout of my Linux user account and log back in!

(1) SmartBoard 885ix (xtra wide 78" resistive surface SmartBoard)
(2) wireless Mic (Radio Shack 75Mhz Lapel Mic) 
(3) pen app (Smart NotebBook for Linux)
(4) virtual TI (TI-83/89 emulator) + WINE
(5) http://screencast-o-matic.com/ (online service)

Next, we enter the world of true SmartBoarding! So, I installed WINE to run Virtual TI right on the SmarBoard! Also, xournal did not work well from the SmartBoard. Every time I started a blank page, the pen would draw a line from the top left hand corner of the screen to the pen! It was time to install Smart NoteBook for Linux.

Otherwise, the wireless mic worked fine as it is platform independent (connects to sound card input). Also, screencast-o-matic worked fine once I added JRE to FireFox. BTW, be careful to use the same audio input/output as you do in Wimpdoze if you are running Ubuntu on a dualboot box and said box is running your SmartBoard in Wimpdoze too!

So, my STUDENT Linux Boxes have Ubuntu 10.04 Desktop plus SAGE (and JRE for 3D graphs in SAGE) + WINE + VTI. Don't forget, I downgraded all my Ubuntu boxes to 32bit so as to make JRE and Flash installation in FireFox easier. 

My TEACHER Linux Boxes also have VLC + Handbrake, WINE + VTI, Smart NoteBook, xournal as well as Flash for Firefox. We recently had our AP exams in Calculus and Computer Science. So, we are using WINE to play vintage StarCraft in APCS class and VLC to watch The Lord of the Rings Trilogy in AP Calculius! I had to a add libdvdcss2 from http://packages.medibuntu.org/ to get VLC to play my DVDs, however. Note that the teacher boxes include all the functionality of the student boxes so I can model what the students need to do in their work. I added VLC to watch videos such as my MP4s and screen-casts on YouTube. I added Handbrake so I can convert my own DVDs to MP4s for YouTube. I have made DVDs from old VHS tapes on my DVDR for YouTube Wednesday documentaries. I've also taken DVR recordings off my cable box and burned them as DVDs for this purpose. I added VTI so the students could follow my using a Graphing Calculator right on the SmartBoard. I mostly use VTI ROMs for TI-83+ and TI-89.

My SERVER Linux Boxes also have JDK, openSSH and vsFTP for APCS. I'm also looking into adding a local SAGE server for Computer Math but we'll leave that for another day. Note that the server boxes have all the functionality of the teacher boxes as I sometimes use the server as a demo machine via a video switch. In this mode, I use the SmartBoard as a glorified video projector as the resistive surface is not connected to the second box. This setup allows me to have one box running Wimpdoze and another running Linux all day without having to reboot. However, I'm needing to use a Wimpdoze box less and less....

BTW, I recently became a Twit on Twitter just so I can Tweet! Take a look at some of my recent tweets:

Joy is after and libdvdread4 libdvdcss2
Happiness is running a vintage server over over during AP Week!  
 
Happiness=setting up a BZFLAG server using BZFS via WINE on my Ubuntu Maverick Meercat 10.04 LTS 32bit Desktop Edition Athlon dual-core!

Yes, I know all things ! But, I celebrated related app! yesterday by downloading a

So, as penance, today I downloaded the app to my droid!
