a jittery bot

I love leaving the lab open after school on Fridays because it’s a nice relaxing time when everyone can take some out to make something before the weekend. At least, that’s the idea.

What really happens is that on most Fridays, there is decent enough attendance, especially from some of our 6th graders, that I find myself running around helping everyone instead of making something myself. BUT I am absolutely not complaining because the alternative of no one coming to Bourn Fridays would be much much sadder.

Anyway, what this means is that when there is that Friday when attendance is minimal and the only kids here are those who know the lab inside and out, I will absolutely take advantage and play around myself. Like this Friday, I got to tinker around with this little guy:

I’ve had this project pinned on our lab’s Pinterest page forever and it feels good to finally get some time to make one!

a lot of soldering and a LoL shield

After much patient soldering (made worse because of OCD nature of yours truly), the LoL shield is finally up and running! These assembly instructions were superb, especially the video on how to straighten all the LEDs for maximum OCD-ness.

It doesn’t last super long on a 9V battery (unsurprisingly) but it was enough to help me advertise the Valentine Day’s edition of Bourn Fridays. On top of that, I now kind of know what “charlieplexing” means!

a light-up whale

I was at FabLearn the last couple of days and one of the highlights was definitely the soft circuits workshop I took. Even though we had only a short amount of time, many of us teachers were determined to finish a stuffed animal project that would light up.

Here’s my little light-up whale:

The whale was one of the standard patterns given to us and I thought that as a former electrical engineer, I would blast right through it. Ha! Yeah, right! Turns out sewing circuits is a LOT different from breadboard, which my mind is way more used to. I can’t tell you how many times I had to undo the stitches and start over.

Looking back, I really should have sat down and drawn out the circuit paths before I jumped into sewing. Once I started sewing, I kept forgetting which path was supposed to connect with which side of which component and kept getting myself confused. If I ever do soft circuits with kids, I will definitely insist they do some planning first!

a little motor

Success! The little motor kit I bought from RAFT has finally been put to the test!

It zips along pretty nicely but it’s probably a bit complicated to use if we want students to really understand the essentials of how to use electromagnetic interactions to generate movement. Something a lot simpler would work a lot better to strip away any “magic” and allow us to focus on the physics. For example, something like this or this.

a way to measure curiosity

Last week, I got to get away from school for a couple of days to attend FabLearn, a conference on digital fabrication in education hosted by our collaborators, Dr. Paulo Blikstein and his lab at Stanford. I met so many interesting people and got to play with various cool toys, including things like TinkerCAD (a simple, easy to use 3D design app on the web with what seems to be some social networking functions as well as upgrades for extending their library of forms with JavaScript), Fritzing (software tool to help with teaching and sharing of electronic circuit designs), and Arduinos (yay!!). I was extremely honored to be asked to be part of the educators panel and the best part for me was meeting my fellow panelists, all of whom are doing such exciting things in this space, e.g. Hack the FutureAthenian School, Castanheiras School in Brazil, and Beam Camp.

The conference gave me so many ideas for projects, collaborations, and ways of thinking about incorporating building and tinkering in K-12 education. If I had to pick one thing that really resonated with me, I would say it has to be the research of Dr. Sherry Hsi from Lawrence Hall of Science. She is working on finding a way to measure and assess curiosity!

In a talk I went to many years ago, Dr. Jeff Goldstein of the National Center for Earth and Space Science Education talked about how science is really just a way to organize curiosity. And now, in almost all of projects we do in our lab, I want kids to wonder about things – how something works, why it works that way, can it work any other way, etc etc. So if there is a way to measure curiosity, that would be an incredible way to assess whether the projects we do and the way we teach is really having the desired effect of making kids more curious. The next step is then empowering them to go one step further and teaching them the tools to satisfy that curiosity, whether by doing research, building prototypes, or what not.

Dr. Hsi talked about a type of study they did where they gave kids cameras and asked them to record everything they wonder about throughout the day. At the end of each week, they looked through the pictures and reflected on what they were curious about. Over the course of months, they can track how curiosity fluctuates and they are also trying to find ways to distinguish different types of curiosity, e.g. how something works and why something doesn’t make sense versus specific facts.

Other highlights from the conference:

  • many cool projects coming out of Mike Eisenberg’s Craft Tech lab at Univ of Colorado, including physical input devices for 3D modeling, 3D printing using kid-friendly materials (like chocolate!!)
  • being introduced to the amazing metal sculptures of Bathsheba Grossman
  • Howtosmile.org
  • the discussion about how to create equitable spaces for tinkering where everyone gets to participate (versus the moms holding jackets problem)
  • instead of aiming for the highest technical level of some project, there is a lot of learning even in the more whimsical and low tech projects
  • LEDs as “gateway drugs”
  • cool products like Tangles (3D Tangrams), DrawBot, Midas, Hummingbird, etc

I am wildly inspired by all that I saw/played with/heard and all the people I met. Can’t wait until next year!

a start of something new…

After too many years in grad school and brief stints as a part-time lecturer at assorted universities in the Bay Area, I’m now embarking on a new journey as the director of a tinkering studio at an independent, all-girls school down in the peninsula. Next year, I hope to be able to say that I’m also teaching engineering at this same school. There is already so much to do, so many toys to play with, and I truly cannot be more excited to be in this new position –  new not only to me but to the school!

I have so, so much to learn which of course is one of the things I love most about teaching in the first place. Signing up to be a teacher is really signing up to be a lifelong student. This is my attempt to record what I’m learning, what I’m inspired by, and what I’m thinking about along the way. But I reserve the right to sometimes, just post cute photos of my cat – don’t say I didn’t warn you.

Teaching at the high-school level wasn’t something I had planned on. In fact, up until about a year ago, I didn’t even think of it as possible career option. A bunch of random events – attending a TEDx conference where I met a really awesome former high school history teacher, Castilleja finding me at a hiring conference even though I didn’t know a job like mine existed and had only registered for science teaching positions – brought me to where I am now.

Of course, the most exciting and rewarding paths are the unforeseen ones, right? I can’t wait!
