Last week, in an effort to keep both my sections of Honors Chemistry moving at the same pace, I found myself with a day to spare in one section. With a unit on lab techniques, specifically titration, quickly approaching, my thought was to pre train this section on the specifics of the laboratory procedure.
Simultaneously, a more playful side of me wanted to bust out the MakeyMakeys from summer science camp and give students some time to explore conductivity, and tinker around a bit repurposing everyday materials to build something just for fun. Then it hit me: Why couldn't we do both?
Back to titration. Digital Drop Counters used to measure the precise volume titrant added to a flask are nearly $100 with the need for more complex software companions for reading data. This it hit me: Could we recreate a Drop Counter using MakeyMakey (along with the pH probes we already have) to simulate the tools we needed for a successful titration? Yes. Sort of! But super fun.
With the help of a few students we devised a simple workflow: First, students wrote a simple program using Scratch that counted clicks when the space bar was pressed. Then, using some fancy graduated cylinder action measured the approximate volume of 1 drop from our Burets, and added a variable to their program that also counted the volume (in mL) of liquid added along with drop number.
Then for the MakeyMakey! By positioning two wires (one connected to ground and the other to the space button on the MakeyMakey) above the Erlenmyer flask with just enough room for a single drop to complete the circuit, and adding some code to delay the click function for any drops that "stick" to the wires, we were able to accurately measure drops added! Finally something more than a video game controller or banana piano!
"Show Your Work!" by Austin Kleon was a very important book for me as an educator. Albeit short, and a bit polarizing, the book reminded me that it sharing the process of my work, not just products, and encouraging my students to do the same, can be a very powerful process if curated strategically.
Not all work is worth sharing, however an attitude of curating the journey towards a final product can yield excellent feedback and subsequently empower one's learning community. Keeping this in mind, I have decided to take Kleon's call to action a step beyond simple tweeting, blogging, and encouraging my students to keep blogs.
This coming year, I will be doing ALL OF MY LESSON PLANNING (classroom teaching AND science camps) on my public website: cyclesoflearning.com. Thus, my website will serve as our classroom LMS, and be an interactive space for all lesson prompts, links, documents ,etc. (Click here to be directed to specific sub page where lessons will be kept).
I am hopeful that this approach will not only share work I find effective with other colleagues, but also force me to organizes my work for students in a more user friendly fashion.
I am blessed to teach at a school that incorporates an "Intersession" program into the month of January. Upon returning from winter vacation, students sign up for a two-week-long, 9am-3pm, course of their choosing. Courses are offered by individual teachers and represent areas they are deeply passionate about and would not have time to expose students to during the normal school year. Courses spanned from Fly Fishing, to Mural Painting, to Molecular Gastronomy, to Virtual Reality and even a course designed to break as many Guinness Records as possible in two weeks. Needless to say, it is incredible to see what students can produce an do, when the pressure of grades are removed and students are given ten full days to slowly dive deep into a subject area.
Over the past two years, in addition to my role as a high school science instructor, I have have developed a growing passion for facilitating youth science camps. The MakeyMakey, given its simple implementation, and incredible potential for open-ended invention has always been an an important tool for sparking an interest in science and invention at my camps. See the two videos below to learn more about the intricacies and development of the MakeyMakey.
As is evident in the above videos, while it is an extremely flexible design tool, when introducing young students to the MakeyMakey it is very tempting for them to immediately begin designing video game controllers. While not inherently a bad thing, the potential for more meaningful invention is incredible. Keeping this in mind, I have always wanted to teach a class that leveraged the MakeyMakey as a tool to empower students with either severe physical or intellectual handicaps. The ability to repurpose everyday objects to interact differently with a keyboard, as well as the ability to program and interact with a myriad of different online modules using physical, tactile objects, opens up a world of possibilities for creating Assistive Technology.
My desire to develop such a course was amplified when I stumbled across this website and the below TEDx talk by educator Tom Heck.
Tom and his students brought to life the exact experience I was dying to create, and his website provided a detailed roadmap for how to make it happen! I immediately contacted Tom, and shared my ideas with him. Tom was gracious, excited to collaborate, and eager to discuss his process.
Back to Intersession. My growing passion for leveraging the MakeyMakey as an invention tool, interest in Assistive Technology development, and Tom's TEDx talk serendipitously overlapped at the right time and it was clear that Intersession would be a perfect opportunity to create such a course! After establishing a strong relationship with a local middle school teacher of exceptional students, a few months of brainstorming, I developed this course, and Assistive Technology devices that leveraged not only MakeyMakey, but also Arduino and Scratch, were created and delivered by a passionate team of 11 Sonoma Academy students. Needless to say, it was one of the most powerful two weeks of my career as an educator!
Below is a playlist with three videos captured when delivering the devices to students.
Below are a myriad of different pictures taken during the two-week Intersession course.
Like many teachers, I have always struggled with making assessment meaningful for students. After reading Show Your Work by Austin Kleon I moved from student Google Doc lab reports in chemistry class to blog posts. My goal was for student to build a public archive of curated work that students can feel proud of. For the past few years student blogging has been a success. Click here for an archive of this year's chemistry blogs.
Keeping the above in mind, this is my first year teaching a robotics class in the curriculum and I wanted to institute the same blogging strategy. Unlike chemistry, my robotics class didn't show as much enthusiasm about the blogging process. When I asked one student why his answer was fascinating: "The stuff we make in Robotics class doesn't feel like school. It feels real. Blogging feels like school. They don't really match."
Over the past two years, many of these student's teachers have embraced blogging, and while I firmly believe it to be a powerful, public and authentic medium for sharing work, it was clear from the above response, and others I have gathered, that the students yearned for a more authentic, less contrived vehicle to break down the barrier between the "real-world" and school environments. Our answer: Instructables! Whenever I have to learn how to create anything I, and my students, use Instructables. It's just what we do.
Because Instructables represents a place where "real" people, go to create "real" things, and is run by a "real" company (Autodesk), whose software we use to create "real" prototypes, it felt like a perfect place to help students, in a Robotics class where building authentic "real" prototypes is core to the class ethos, engage in a type of "real" world product showcasing. Once the decision was made (two weeks ago), I jumped in headfirst, and invited students to use Instructables to post not only share their most recent inventions, but outline their design process.
The student's products exceeded my expectations and reminded the power of not only a public product, but also how the power of outlining and unpacking the invention process into steps for others to follow. Instructables provides a fabulous medium where this process happens, not via a teacher created rubric, but via observing the thousands of examples that already exist on their website! Below are three student created examples from my Robotics class at Sonoma Academy.
Shortly after he left The Daily Show Jon Stewart told Fresh Air's Terry Gross that, "It is through intense structure that I find the safety to be creative." As a teacher, this statement resonated with me. I love the lesson planning process and Stewart's quote really encapsulated why I do. Through a structured, directional process, even the most "control freakish" teachers (I fall in this category) can carve out space that allows for intense student creativity, showcase, mess, disaster, invention, tears, high fives, and the myriad of other emotions that come along with LEARNING, when the lesson plan process is given the respect that it deserves.
On to a more tangible example of what I am referring to. This year is my first teaching a Robotics class in the curriculum, rather than as a team, club or after school workshop. My fear in teaching the class was that it would turn into a "club" like environment full of "BattleBot Obsession" and void of meaningful discussion around programming, mechanical engineering, and the ethical implications associated with deciding which tasks we keep for ourselves, and this we offload to our "machines.". However, you can't deny that placing technology such as littleBits, Lego NXT, MakeyMakey, VEX, TETRIX, SAM Labs, Arduino, and the many other tools we have and will explore in the hands of high school students isn't also a recipe for fun, and at times, fun just for fun's sake!
Click here for an example of a similar invention cycle template. As you can see, this template positions the learning of basic NXT programming, rather than as an individual project, in the context of the larger, more meaningful task to "smash" together the littleBits and NXT systems to do something that is currently difficulty and/or expensive to do: build a functional remote control for an NXT robot. See a picture of a final product below.
Upon conclusion of the RC project, students then blogged about their process, and reflected on ways other tools could be combined to create, new, unusual and useful outcomes. Click here to read student blogs. This project was then followed up with another project where students leveraged a more "Human-Centered" design process to build an NXT powered device that would improve the quality of life for another faculty member on campus.
Like the project described above, the initial part of this invention cycle involved learning basic skills in the context of the overall plan. This time, students needed to framliarize themselves with a more complex programming language (RobotC) and in doing so, built "BattleBots". Per my fear described in the second paragraph, the structure of the invention cycle lesson plan kept me centered and focused on the overall, more meaningful goal rather than distract from learning tasks that require more rigor and depth of focus. This structure carved out a space where the pure fun of constructing a BattleBot existed in the context of an overall, more meaningful process. One student even built an NXT Robot Flamethrower as her BattleBot! Love it! See video below.
Teaching Robotics is teaching me that structure and student creativity can exist together and can, if positioned correctly, be symbiotic.
