Electricity + OLPC Lesson Plans (Grammar School Science)

This post is about the lesson plans that I created for the Electricity chapter of the class 6, 7, and 8 students back in Meerut, India. They include the basic concepts, some examples of classroom interaction and homework, as well as the low-cost science experiments (materials and explanations) that I produced. Additionally included are notes on the learning curve and student interaction with the OLPC laptops. As with the OLPC report, this one wasn't written with a clear audience, and in hindsight, should have been separated into a mostly-science report and a mostly-OLPC report. C'est la vie. Take it or leave it.

It should be noted that I've posted this content just for blog readers - mostly friends and family. As the folks over at Iridescent Inc have discovered, random lesson plans on the internet aren't too helpful for educators, there are plenty of bad ones out there to sift through (I'd like to think mine are good although I'm sure we all would). The times are changing, and now even lesson plans are out - replaced by simpler concept maps that teachers can build around.

OLPC Laptops in the Classroom - report

This post goes back to April when I was teaching science to the 6th, 7th, and 8th graders
at Chiragh Grammar School, in Meerut, India. I was experimenting with the role of the low cost, rugged, OLPC laptop computers in science classrooms.
So how did it go? Well I just so happened to write it all up! Although I wrote up this full report (20 pages) in early May, we weren't sure where the report should go. If you're interested in reading it all, find it over at Iridescent Inc -- the non-profit science education group I've been involved with the past few years in Los Angeles.

Since I wasn't sure the audience that I was writing this for, nor where the report would show up, I didn't put a whole lot of effort into polishing it (grammatically or otherwise). That said, I put in our experiences and hope that others can benefit from what we learned!

Leaving Meerut - Academic Edition

My time in Meerut, India has come to a close, and so I thought I'd post some pictures from the classroom over the last month. Hopefully I'll have time for a non-academic "Leaving Meerut" post as well.


First off, I've finished my time as science teacher for 6th, 7th, and 8th class here at Chiragh Grammar School. I've written a roughly one-month syllabus for each class, to teach Electricity and Magnetism, using loads of hands-on experiments, at varying levels of complexity. Of course the experiments require only very simple, inexpensive, easily obtainable materials! I'm currently not sure where the syllabus/report will be posted, but It will probably be in conjunction with our friends over at Iridescent Inc. and have some sort of a free-to-use Creative Commons license.

I'm glad that I got the chance to be a teacher, and I really learned more than I had thought I would. I was surprised to hear the exact same questions that I used to pose to teachers before a test, and this time around they seem like such silly questions. "Will there be multiple choice? Will there be true/false?" It doesn't matter! Study the content! :-)

Most positive realization: Students look up (metaphorically) at the content of the course as a series of facts that are hard to understand, and thus must be memorized. Teachers look down (metaphorically) at the content of the course as one, completely related string of interdependent ideas. Thus, the teachers job is to (sure, why not. once again, metaphorically) weld the links of steel into a chain of knowledge that can be relied upon for strength in later courses. It just blew me away when I realized the way I used to see content, and the way I see it now, after teaching it.

Second, I've finished my time as a science teacher who was using the OLPC laptops in an unofficial deployment! Very related in that the initial hope was to use the OLPCs as the platform for the hands-on experiments. Unfortunately, there were limited opportunities for this. But to turn a negative into a positive, the laptops will stay here for the students to learn computer skills, and are available for all teachers at the school to use in their curriculum. Additionally, I've written another document which outlines what it was like and the hurdles to using these OLPCs in an unofficial deployment. More to come on where that will be posted later as well. (Psst! One of my recent blog postings was covered by someone else! Check me out!)

Just a regular day at the office.
Theme in the last 5 pictures? We're not exactly a One Laptop Per Child deployment.
More like a One Laptop Per Multiple Children deployment! OLPMC!
6th Class happily showing the XOs they use.
8th Class is a bit more stoic, although equally appreciative!

Winner for third-world Skyping: OLPC!

New Picture: Me in my normal Skype environment (wireless!).

It occured to me the other day that at my fingertips were two options for wanting to talk to the US from over here in Asia:

Option 1: Desktop computer, external monitor, wireless receiver, Uninteruppted Power Supply (UPS) backup battery
Option 2: OLPC XO laptop (built in wireless, monitor, battery (UPS))

Option 1: Full desktop setup (UPS was faulty so it was removed [and I lost the first version of this blog posting due to a power outage!])

Option 2: OLPC XO Laptop (Cup of chai optional)

Now to either of the above lists I just add a standard headset with microphone and chat away! (In fact, if the conditions are perfect, don't even add the headset to the OLPC, just use the Built in microhphone, speakers, and webcam!)

For the audiophiles out there, it turns out that the XO laptop gives way better filtering of background noise (I'm in a 20' x 30' concrete room)! Way to go OLPC team! (I would have thought it would be standard due to both computers running Skype brand software, but there is a repeatable difference!)

The official page for installing Skype on the OLPC laptops can be found here, but I used an amalgamation of help forums, etc. because I installed it a while back (and/or didn't see the main page... :-) )

(Now looking into the status of Google Talk on the OLPC (Seems like might have to use a third-party for billing to call to non-computers at the other end). -- suggestions welcome!)

1 more day to Enroll!

Just wanted to give a quick update on my status -- I arrived in Delhi a few days ago and was whisked away from the airport around midnight by some new friends - the principle of the Chiragh Grammar School (in Meerut, India) and her son. Over the past few days we've been getting ready for the new school year to start- April 2nd is just around the corner!

(This is the quality picture taken from the OLPC laptop -- click for full resolution.)

(Side note: I'm posting this from one of the OLPC laptops that the school had donated from friends in the US. Lots more to come on these gems, but the current point is that I can't post pictures from them to the blog, although I can post video from them to the blog, see entry a day or so ago. So I'll have to edit this post to add pics separately, bummer.)

The current plan for teaching is to try to elevate the student's understanding of electricity and magnetism. These subjects are covered in their science class and text books in class 6, 7, and 8, to varying degrees. Since I'll have the small, combined 7th and 8th graders, I have some freedom with respect to the depth of coverage. I'm going to try and let the students complete some hands-on-hardware experiments, as well as software simulations on the laptops. As such, the first few periods are set aside for the students to 'explore' (that's code for play with) the laptops -- then it's down to business! Keep checking back as I may try to post some of the documentation generated in the course.

More to come!
