How to Make a Human Drum kit

In my Masters of Educational Technology program at Michigan State we had the opportunity to host a Maker Faire. We broke up into groups and each group designed a maker “station”. Our group created a human drum kit and it turned out awesome! I want to share a “how-to” for building a human drum kit.

Purpose: The purpose of this activity is to leverage the power of a Makey Makey and Scratch programming to create a set up where one person in a group is a drummer, and each of the other people in the group are part of the drum kit (snare, cymbals, etc.). When the “drummer” touches the hand of the person connected to the snare wire it will complete the circuit causing the snare sound (in Scratch) to play. If you have a person for each part of the drum kit you will then have a fully operational drum set (made of people).

Materials Needed

  • Makey Makey
  • Several Alligator clips and connecting wires
  • Conductive thread (This has two uses, first it is sewn into the “drummers” head band, second it extends the connections between the Makey Makey and the parts of the drum kit.)
  • Pipe Cleaners (To create the bracelets that parts of the drum kit will wear.)
  • Copper Tape (To wrap around the pipe cleaners, so that the wristbands are conductive.)
  • A computer with working speakers that is running this Scratch Program

For the set up I will be referencing the diagram below. The blue dotted lines represent conductive thread connected to wristbands (pipe cleaners wrapped in copper tape) which must be touching human skin. The red dotted line is conductive thread connected from the “earth” part of the Makey Makey to a headband. The headband had conductive thread woven into it. The thread must be touching the forehead (skin). With the scratch program running on the computer a person only needs to touch the drummer for that instrument to sound. This completes the circuit which sends the signal to the computer.

A special note about the kick drum: You can use a wrist band and a person for the kick drum. We found that it worked better if we attached the blue kick drum wire to copper tape on the floor. Then when the drummer touched it with their bare foot they completed the circuit for the kick drum. This allowed for the kick drum to feel more natural. (You could also connect the blue wire to tin foil and wrap it around the person’s shoe if you didn’t want to go barefoot.)

Human Drum Kit Set up

 

General Suggestions

Here are a few suggestions after having been through the project. First, tape down the wires. This keeps them much more organized. Second, make sure there are many points of contact for the headband. Third, make sure no wires are touching the headband wire. This unintentionally completes the circuit. Last, make sure that the copper on the wristbands has a good contact with human skin. Without that you can’t complete the circuit.

Below are a few images and videos of the drum kit in action. If you have any questions at all please leave a comment or tweet me and I’d be happy to point you in the right direction.

Lesson Plan Version 5.0: Final Revision

Over the course of the last week and a half I’ve taken my old lesson plan over the Fundamental Theorem of Calculus and made several revisions to it as it was examined through different frameworks. The lesson plan was originally very traditional (direct instruction to start, modeling with guided instruction, independent practice, and follow up the next day). However, as I looked at it through different lenses I made several modifications to the original lesson plan that made a better use of technology, made the learning more accessible and engaging, and leveraged networks in an effective way. You can check out my original lesson plan and my revised lesson plan directly below it, here.

Major Revisions

I want to first highlight some of the major revisions I implemented and my justification for them. I started with the beginning of the lesson. I wanted to start with some sort of inquiry style activity to get students familiar with the concepts on their own terms. I did this because often when students are faced with tasks lacking apparent meaning or logic, it will be “difficult for them (students) to learn with understanding at the start; they may need to take time to explore underlying concepts and to generate connections” (Bransford, Brown, Cocking, 1999, p. 58). You can check out the activity I developed and the Wolfram Alpha animation it’s centered around.

In addition to making a shift towards inquiry, I wanted to leverage technology in a more effective way. To do that I decided that each student would do the activity mentioned above, on a Google doc. This will allow me to easily follow along and provide feedback as they work through the activity. Frequent and timely feedback is incredibly important to the learning process (Bradsford et al, 1999, p. 59). During the proof stage of the lesson, I will have them participate in a backchannel via Google Docs, providing me with questions they still have and a summary of their understanding of the proof. I can then send this out to a few teachers in my network and get feedback on how to approach whatever student misconceptions still exist. I will still be using “low tech” methods in the collaborative whiteboarding, but will be having them share out their solutions with the class in a more structured way. I will be pushing them to verbally explain their thinking process as they worked through each problem. This gives students another means by which to express their understanding (beyond writing) which breaks down barriers to learning by allowing multiple means of expression (Rose and Gravel, 2011).

One of my last revisions was to create a more focused prompt for students focus on in there weekly blog reflection. My research on Gifted and Talented Learners suggested that it’s good for students to consider how they used inductive and deductive learning so I built that into the learning prompt (Sheffield, 1994, p. xvi). In addition to the blog post post they will also have to give constructive feedback on their blog posts to each other. They will look at a peer’s post through a critical lens which will help students further explore their own understanding of the concept.

Thoughts on the Revision Process

This process has allowed me to see assessment and evaluation differently. Some of the technology I’ve implemented will allow me to assess and provide feedback during and after the lesson in a much more effective way. In other lessons I want to build in a better continuous feedback loop to help students understand where they’re at in the learning process. I tried to do this before, but I think I have some techniques that will allow me to do a better job of it in the future.

More broadly speaking I’ve grown as a professional in this process. Now that I’ve studied the constructivist approach to learning, Universal Design for Learning, the TPACK framework, and network learning I will be able to better utilize these frameworks in my other lessons. I won’t do it in such a formal way, but as I revise in the future I will look through each one of these lenses to create effective lessons that integrate technology and reach more learners. These are powerful tools that I didn’t have prior to going through those revisions. I think being a quality educator means being able to evaluate lessons from different perspectives and I think I’m closer to that standard now.
