ISTE 2011: LEGO Workshops (Post 2 of 2)

26 Jul

ISTE 2011 Post #2: Notes: Working my way through my conference notes. Trying to get them out of the brain and onto the page. 

LEGO Sponsored Workshop: Revolution through Serious Play and WeDo 

I have only one big gripe as a newbie at ISTE this year; the online program was a pain in the neck to navigate. Searching by keywords brought up a few workshops and presentations, but completely ignored others. “Sponsor Activities” weren’t listed under “Presentations by Time” and… well… I won’t waste your time venting about the schedule. The short of it is that I paid for a half-day NXT workshop, when I could have attended a free sponsored workshop on the same topic by the same presenter, and I almost missed out on the opportunity to attend this LEGO WeDo workshop that I completely lucked into when I happened to walk by and I recognized the familiar kits.

Part 1: Serious Play

I slipped into the room a few minutes late and took an empty seat. We sat in pairs at workstations, each containing a WeDo Kit and a laptop. While I was interested in hearing what the presenter, Kathy Holberg, would share about WeDo, I was also interested in:

1) Connecting with other educators who are using WeDo in the K-6 classroom

2) Learning about “LEGO Serious Play“, something I had read about, but had never seen.

Kathy started by giving us this brief overview of LEGO Serious Play (LSP). LSP is used as a training tool or training methodology in a variety of industries and businesses, as well as in schools, for purposes such as team building, fostering out-of-box thinking, encouraging the expression of feelings, ice-breaking activities, making connections, aiding awareness of others’ feelings, and developing listening skills. It is also used to improve communication skills, logical thinking, and creative thinking. It is a vehicle for exploring metaphoric language and thoughts.

After her overview, Kathy gave each participant a bag of LEGO Serious Play parts and this prompt:

Construct a model that represents a hands-on STEM lesson in your classroom. Try to use all the pieces.

I looked at the meager pile of random pieces lying on the table in front of me, and thought “Really? Do that? With these?” I looked over at my neighbor; she appeared equally hesitant. Regardless, we set to work clicking and snapping pieces together.  What I found interesting, is that due to the limited number of pieces to choose from, I was quickly forced to let go of any desire to create a specific or concrete representation of an object or idea and to instead embrace my creativity and explore which pieces I could use to represent an object or symbolize an idea. It got easier and easier.

After five minutes, Kathy stopped us and asked us to turn to our neighbor to describe our models regardless of where we were in the building stage. This was my model…

…and here is my partner, LeRhonda’s (@lgreats) model.

I love that even with so few pieces to work with, we were both still able to create and share something unique regarding our ideas on STEM lessons in the classroom.

According to Kathy, a teacher’s, or facilitator’s, main role during a Serious Play build, is to ask questions and move around the room without introducing any type of bias into the building effort. For example, a facilitator should not say “Good job, Tom”, because it could create the impression that there is a “good way” or a “bad way” to complete the activity. The goal is to have everyone be comfortable using the LEGO blocks as a vehicle to explore or express an idea, a thought, or a feeling without worrying about the consequences of not doing it well, or right, or as good as the next guy.

Kathy made sure to clarify that the LEGO Serious Play methodology required specific training in regards to how to“properly” write a challenge question, set the stage for using LSP (LEGO Serious Play), work with students when they are telling their stories, and  connect the activities to student learning, but I would venture to say that any teacher with a bunch of LEGO bricks and a good grasp on inquiry-based, constructivist instruction could engage a classroom in some “LEGO Serious Play”. 

That’s not to say that teachers wouldn’t benefit from a formal LSP training or from having access to specific LSP kits. It’s more to say that the use of LEGOs or other manipulatives to explore thoughts, ideas, and feelings is something that could be done with little to no additional cost to a school that already has access to LEGOs, granted a teacher did a little research to understand the core concepts involved in the LSP model.

Part 2: LEGO WeDo

Kathy next introduced us to the new LEGO Education WeDo Robotics Extension Activity Bundle. Basically, LEGO took the same basic 12 builds for the WeDo Kits and then created a new curriculum set to connect the builds with subject matter from PE, language arts, and social studies. I’m not too interested in purchasing this extension pack. I tend to naturally make cross-curricular connections when using the kits. For teachers who prefer to teach from a written curriculum, or for new teachers who may benefit from the structure of a pre-designed curriculum, it will be great. For those of us who nerd out on the creative aspects of unit planning and lesson writing, it may be less appealing.

The rest of the workshop gave teachers time to explore the kits and build a model.

Here are few WeDo tips Kathy shared: 

1.Use “fun foam” to cover the WeDo kit lids.  Kathy likes using fun foam on the lids so that students don’t get distracted by the images on the lids, so they can use the lid as a building mat since the LEGOs don’t bounce off the fun foam, and finally so the lid can be used as a tray to display the students’ builds.

2. Create an “NXT” parts diagram for organization. Kathy creates a system for arranging the kits and then takes a picture for the kids to help them stay organized. (I thought about doing this when I initially started to work with the kits, but decided not to for the sake of time. I think it’s a great idea for teachers who are uber-organizers.) 

My favorite tip… Use “Alt-tab” to quickly see the desktop when working in WeDo. (If you are familiar with the WeDo software interface then you know it defaults to a full-screen view. This tip will come in handy for sure.)

A Fun Fact: Black axels are even. Grey axels are odd. (I never noticed that.)

During the workshop, Kathy was kind enough to give me the opportunity to plug my blog and to invite teachers using the WeDo kits  to send ideas, lessons, or reflections that I could include in a post or put up as a “guest blogger post”.  Although a few people expressed interested in sharing or posting, I haven’t heard from anyone yet. The offer stands! If you want to get something out there about elementary robotics, but don’t want to commit to your own blog… just let me know.

By the way… we got to keep our LSP kits and we got these sweet keychains. Pretty cool, huh? 😉

ISTE 2011 LEGO Workshops (Post 1 of 2)

15 Jul

I’ve been wanting to post my notes from the LEGO workshops I attended at ISTE 2011, but I’ve been procrastinating. I need to post them so that I can make room in my brain for some new ideas. So here goes!

ISTE 2011 Post #1: Notes from Sunday June 26, 2011…

Introduction to Classroom Robotics: Computer Science in Motion!

The workshop room was full of people seated behind workstations. Each workstation had a LEGO NXT kit, a pre-built Domabot with a few sensors attached, and a computer with NXT-G software.

Our presenter was Christopher Michaud, a Music Teacher at  Nebo Elementary School in Dallas, Georgia, and a graduate from Temple University’s Music program. (Woot! Philadelphia in the house.) He taught himself to program, and now in addition to teaching music, he teaches a computer science curriculum for grades 3-5. He focuses mainly on Open Office/ Alice/ Python/ and Robotics and has a terrific website with loads of great resources. (I couldn’t help but secretly love the fact that his background is in music, since my undergrad was a music technology degree. music + math + curiosity = awesome life!)

Chris started the workshop with a Powerpoint presentation in which he provided us with a brief overview of his goals for the workshop: Build, Program, Experiment, Apply, and listed a few of his reasons for teaching robotics at the elementary level, including my favorite, “Robots are cool.”  (He has headier reasons listed in the presentation that will make for stronger plugs when trying to sell a robotics program to your administration, so  I encourage you to check it out.)

The remainder of the Powerpoint presentation was a bit of NXT Robotics 101, which sensors did what and the like, and was a perfect introduction to NXT robotics.

Within just a few minutes of starting the first workshop activity, getting the domabot to drive in a square, I, and the woman next to me, realized that this was perhaps a true beginners workshop. (As in, many people in the room had never even touched an NXT kit before. I guess it’s time for me to bump my status up to advanced beginner.) My partner was open to going off script to explore some of the features of NXT-G that we were curious about and so we started messing about, clicking on buttons and pulling down menus.

Chris came over and asked how we were doing. We confessed and told him we had gone rogue.

Lucky for us, he was not at all offended and was an excellent differentiator of instruction and he immediately found us a task that would both challenge us and highlight a few new features of the software that we were not familiar with. We worked on “Simple Pi Challenge 1” and “Simple Pi Challenge 2”,  two worksheets which not only provided us with an excellent opportunity to practice writing formulas within the NXT-G software, but which also gave us great take-away lesson to use in the classroom. It provides a perfect opportunity for students to see “Pi in action”.

Once we had worked our way through that challenge, we quickly discussed what else we’d like to get out of the remaining time.

We both admitted that we had no idea how to use… DATA WIRES.

Yep. It’s true. I’ve been avoiding them. I don’t why. I think it’s because I learn so many things just by messing around or through trial and error. But when I approached data wires in this manner… there was a whole lot of “error” at the end of every “trial”. Chris was great, and he broke datawires down for us and helped make them seem at least approachable. (I’ll try to post a simple example of the use of datawires at some point for anyone else who is hesitating on getting a handle on them. Or maybe someone has a great intro resource they could suggest…)

Here are few helpful suggestions Chris made for teachers who are about to take on robotics…

1. Start with a robot built. “Kids understand build. Programming is more difficult.” The domabot is great example of a robot you can easily have ready for students to work with.

2 .Organize the room with computers on the perimeter and workspace in the middle. Have a place  in the room where it is possible to have students with empty hands.

Here’s some new vocabulary for neophyte robot programmers:

Swing turn: 1 wheel turns 1 wheel doesn’t. (Think “pivot” on a basketball court.)

Point turn: 1 wheel turns forward, the other goes in reverse. (Think… I don’t know… any ideas?)

To be honest. That’s all I got for you. Those are my notes. I know. Not very impressive. Which might be why I was procrastinating. But at least there out of my head and on the page. 😉

Thanks Chris! I finally learned to use variables, custom blocks, data wires, and the formula review in NXT-G. It’s about time. My students better get ready… next year will be a whole new ball game!

LEGO WeDo Vehicle Challenge: Using WeDo kits with older students

20 Jun

The LEGO WeDo kit is designed and marketed for early elementary children. It’s so basic that even a first grader can use it, but be careful not to write this kit off as a “just-for-the-little-kids” kit too quickly.

This year, one of my favorite mini-lessons with the 7-9th grade students in the after school STEM club was this “WeDo Vehicle Challenge”:

Design a WeDo vehicle that has either 2, 3, or 4 wheels. Use only the pieces in the Wedo kit. The vehicle does not need to have steering, but it must be able to drive forward and in reverse. Innovation is encouraged. You have two class periods (1 hour each). We’ll present at the end of the second.

The kids usually take a look at the WeDo kit and presume the challenge will not be much of a challenge. Once the students get started, it isn’t long at all before they realize what makes it challenging; there is only one motor, the motor is fairly heavy relative to the parts, and that the axle sticks straight out of the center of the motor. Hmmm….

I’m guessing the challenge is probably easier for students that have prior experience working with LEGO kits and robotics; I’m not sure. (Let me know if you try it.) All my students were new to working with the NXT kits when I tried the WeDo lesson. I wanted to see how they worked when asked to think out of the box and to be creative. Following a blueprint is great for developing spatial skills and following instructions, but it doesn’t necessarily foster innovative thinking.  I found that forcing the students to work with the limited parts of the WeDo kit encouraged them to be persistent, to attempt multiple solutions, to redesign and improve, and to work together.

I’m curious if other teachers and after-school educators have tried using the WeDo kits with older students? Let me know!

Here are a few examples of our WeDo vehicle designs if you are curious… (The kids filmed the clips.)

Taking Damien Kee’s NXT “Mexican Wave Activity” for a Test Drive

16 Jun

In my last post about the Tufts LEGO Engineering Symposium, I mentioned Damien Kee‘s  presentation and included an embedded  video of his NXT “Mexican Wave” activity.

Yesterday morning, I tried the activity with a group of 21 fifth graders that had never worked with robotics before and it was a blast! It was the perfect activity for introducing the kids to the NXT robots and the NXT-G software.

We met from 9:30-12:15 and took a 15 minute snack break, so all told, we had about 2.5 hours to try to meet the following three objectives:

1) Work collaboratively in small groups to program the NXT Domabot to move from one specified location to another. Time permitting, write a program to turn the robot around and have it return to it’s starting position.

2) Gain a basic understanding of what sensors and thresholds are and find out how they apply to today’s activity.

3)Work collaboratively as a class to program all five NXT Domabots to do a wave and at least one additional choreographed movement.

Students collaborated well and worked hard and met all three objectives by lunch!

After reviewing the objectives, we warmed up with a five minute activity called “Computer Says”. (The activity is similar to Simon Says. I am the computer; students are the robots. Robots should only follow programs that start with “Computer says”) Students made three lines and faced me.

For Round 1, I said, “First we’ll learn use a motor block to run simple programs. Let’s try a few.” I then led them through a few simple commands,  “Computer says take one step forward.”  “Computer says take one step back”.

In Round 2, I said, “Next we’ll learn to use a “wait-for-sensor block and write slightly more complex programs.” I then gave a few commands like these: “Computer says wait until you hear me clap, then take one step forward. Computer says, wait until I shout loudly and then jump”

And finally for Round 3, I said, “For our third objective, we will have to collaborate to write a series of programs to get our robots to work together to create a movement wave. Let’s try to run three programs at once and see what happens. Computer says, Line 1 robots, wait until I clap then put both hands in the air and back down again. Line 2 robots, wait until I clap, then wait one second, then put both hands in the air and back down again.  Line 3 robots, wait until I clap, then wait two seconds, then then put both hands in the air and back down again.” I clapped my hands and watched as the students did a perfect mini-Mexican-wave!

The whole activity took less than 5-minutes, but it helped to build a context for what came next. Being able to refer back to the warm-up came in especially handy when we started thinking about how to program the robots to do a wave.

After our warm-up, students then learned to move their robots using a single motor block. As recommended by Damien in his presentation, I placed two lines of tape on the floor at a random distance from each other and then students worked to program their robots to start with wheels on the first line and stop with wheels on the second line. They set to work trying different motor on durations and very quickly developed an appreciation for the decimal point! If 5 rotations were too many, they tried 4, then 4.5, 4.6, 4.7…

They began to see that trial and error and persistence were important for solving this problem, and they experienced the intrinsic joy that came along with finding an exact solution to a problem.

Soon all groups had mastered the line-to-line challenge and were on to trying to figure out how to turn the robot around and bring it home. Despite my having mentioned that changing the “degree” parameter of the motor block to 180° would not turn their robot around, all the groups tried that strategy first, which led to a series of great teachable moments surrounding what “rotation” meant in the motor block. After some experimentation with the remaining parameters in the motor block, groups soon started to catch on that the steering parameter in combination with the duration setting was the ticket to that 180° turn. At least two of the five groups got the turn close to an exact 180° turn, and the remaining groups were well on their way before I cut them off and moved on to objective 2.

Once the kids had a general sense of how to move their robots and turn them, we regrouped and I introduced them to the sound sensor and to the threshold parameter.

As I usually do when explaining threshold to kids, I said, “I bet you already know what threshold means. Let me show you. Listen to my voice and when I reach your threshold between soft and loud, clap.”

I then talk very quietly and get progressively louder until they clap. I repeat and set the threshold for “really loud”. I do a few more examples of simple thresholds they understand. For example, their threshold for drinking hot liquids. I quickly made the correlation to the threshold parameter on the  sensor block. Students seemed confident they understood the wait-for-sound block and so we moved directly on to discuss how to create a wave.

To plan the wave, we created a chart on the wall that sketched what each group needed to do and then parted. We met back up about five minutes later.

On the kids’ first try, the robots took off and executed a perfect little wave. Wow! We had thirty minutes left to add a choreographed movement of our choice. We lined up 5 students to represent the five robots and planned our dance move. Groups ran off in all directions to program. Shortly after we met back up, pushed run, waited for the signal and yelled “Go” What came next was…

Terrible. Our little robots were all over the place. And so we began to learn about collaborative trouble-shooting. We came back to the line over and over again, each time it got better, but something wouldn’t be quite right.

With one minute left and groups scrambling to download their last attempts, I called them back to the line. The room was quiet. Thumbs went up to signal all programs were running. Their classroom teacher quietly counted “1-2-3” and then the kids yelled “Go!” one last time. You can see for yourself the fruits of their efforts in our video. The simple sequence of movements won’t blow your mind… but the kids’ cheers and screams of enthusiasm may brighten your day. 

Meet them where they are…

8 Feb

We’ve all heard the phrase, “Meet students where they are.” Today, I saw once again how transformative meeting a student where he or she is can be.

As I’ve mentioned in previous posts, the students who currently attend after-school robotics club, didn’t truly elect to join. They kind of got roped into it. In total there are eight students, six young men and two young women. One of the young women is especially quiet and up until today has been very shy about participating in most activities. I’ve tried to encourage her and to use my best teaching strategies to engage her, but honestly… I was beginning to think she just was not connecting to the activities and that she simply had no interest in robotics and engineering.

I ran 20 minutes late getting to club today because of a doctor’s appointment. The laptops were still down at the elementary school from Friday’s lesson with the first graders, and I didn’t have time to move them before our meeting.

I made a last-minute decision to switch up my plan for the day. (Something I don’t usually do.) Instead of working with the NXT kits and software, I took the middle school club down to the elementary lab to explore the LEGO WeDo kits.

What I observed was awesome. That quiet, non-participating  young woman I just mentioned explored and built models non-stop for the entire meeting. She then elected to stay an extra twenty-five minutes, leaving her and two others just five minutes to run to the dining hall for dinner!

She worked independently for the most part and focused on using the “Getting Started” tutorials to build the models shown. I mainly observed. As she completed each model, I engaged her in a quick conversation and asked a few guiding questions.

She was a completely different student than I had previously seen. She was 100% engaged. Check it out! Hard at work and completely in to what she’s doing! (And with no coaxing or encouraging.)

I could see the confidence in her building right in front of me. It was amazing. I asked her if she’d like me to bring a WeDo kit to future club meetings so she could continue working with one. The answer? “Yes, please.”

The WeDo kit was perfect for introducing her to some important concepts. In just one hour, we were able to explore the movement of gears, the function of a motor, the use of a belt, and how programs are used to command the models’ movements. All she needed was to have the materials kit and the computer interface simplified. With no previous exposure to programming or model building, the NXT kit and software had been overwhelming for her, keeping her from getting involved.

When I said, “You know. The models you were building and programming today aren’t that different from the ones we’ve been working with up the road”, her face completely lit up. I think today’s experience has changed her ideas about “robotics club” and I’m excited to see where the excitement leads.

I will definitely continue to explore the benefits of using the LEGO WeDo kits with some of the older students. In addition to providing the perfect scaffolded introduction to robotics, it also brought out the playful and creative side of the students. When one student asked, “How are we supposed to build a robot if we don’t have any instructions?”, it led to a great conversation about the importance of play and trial and error.

It was a really good meeting today. There’s plenty of room for improvement, but it was really good. I can never figure out who is learning more… me or my students? I like to think we’re both learning.



Kick off a “belt” lesson with a 1-2-3 video connect!

4 Feb

If you plan to teach your elementary (or middle school) students how a belt works, consider kicking off the lesson with this 1-2-3 video connect:

  1. (Something fun and familiar) Show a video snippet of a DJ spinning on turntables
  2. (Something informational that uses plain language and supporting visuals) Show the first minute or two of this belt-drive turn table explanation video
  3. (Connect) Either review what has been learned or introduce what will be learned!

It’s as easy as 1-2-3 and can be done in five minutes or less!

Tip: I embed the videos in a Prezi so that they are located in one convenient spot and so I don’t have to worry about distracting comments under the videos that may be inappropriate for younger students.

Let go… you don’t need to know everything.

21 Jan

I have no prior experience working with robotics. In fact, what I do know when it comes to robotics is basically that I don’t know much at all. I also know that the activities we are doing so far in the after school club are not mind-blowing, world shifting activities that will win us any competitions, be heralded as wildly innovative, or require immediate patent applications (not just yet anyways)… and that’s ok.

We have to start somewhere.

I don’t know much about robots… but I do know a whole lot about kids. I also know an awful lot about problem solving, collaborating, asking for help, experimenting, being resilient, finding experts, locating resources, and mediating conversations. I know about boundaries and high expectations. I know about trust. So when I show up for our new after school robotics program, that’s what I bank on. I do my best to model and teach the skills I do know about and I get out of their way for the rest. So far this plan seems to be working well. See for yourself.

Keep in mind, the students in the club were not selected to participate in the program based on their excellent math or science skills, and they were not selected because they show great promise in any specific academic area or have outstanding GPAs or have consistently good behavior. (Honestly, I have no idea what type of students they are during the school day — which I like.) In fact, the students in the program weren’t selected at all. We are together by complete chance; their previous after school program finished early in the season, they needed something to do, and I came along and said, “Hey, try this with me. I don’t really have a plan but I know we can make it great if we work together.”

In a million years, I could not have picked or selected a more perfect group to start with. They are learning so quickly and they are proof that you just have to jump in and trust the kids to help you figure out where to go to next.

At the end of each meeting, we review our time together and each member shares his or her biggest “take-away” lesson for the day. I’m sure you can imagine how it felt when, completely unsolicited, these are the types of responses students gave:

“I learned that even if its hard at first, you have to try again, because you can figure it out.”

Or how about this comment caught on tape by his teammate, “I was just tampering with the program and I actually figured something out.” (Pay attention to that smile. Its the intrinsic-joy-smile and it’s what keeps me hooked on teaching.)

My biggest take-away lesson learned so far…

Let go. Let go of fears of inadequacy. Let go of the idea that you have to “teach” kids and embrace the idea that you can “facilitate learning”. Let go. You don’t need to know everything

(For the record… I’m a realist. I know there will be a point where my mathematical and scientific knowledge will not be enough. Not to worry. I have a plan. I have a few SMEs standing at the ready and I am in regular contact with a local university partner. When we are ready for the next step, we will reach out for help.)

I promised to share practical classroom tips and ideas so before I say good-bye for the weekend…

Here’s a super easy to implement strategy for integrating technology in your club or classroom:

I keep a Flip Camera available for the students in the club to use when they want to document. Anyone can use the camera, anytime they want. Sometimes I use it. Sometimes they use it. The camera provides a good break for a student who is frustrated. I say, “Why don’t you walk away for a moment and document?” It gets him or her up and moving around, gives him an opportunity to stay involved, and in many cases he ends up observing a peer working through the same problem.

(BTW…This strategy works great with kids who have a difficult time staying still in the classroom. You don’t have to do anything with the footage. It’s more that the student stays involves, continues to learn, and does not disrupt the class.)
