Just “Scratch”-ing the Surface


While one group of students are investigating the 3D printer, I have another group exploring yet another technological territory.  It started two years ago when one of my boys found a program called “Scratch“. He tried to tell me about how you could learn to code by using it.  I was not willing to investigate computer programming back then.  I saw it as “game-playing” and failed to see its educational value.  Lucky for me, this student persisted and continued to produce “games” for others to play.  It wasn’t until I saw the Hour of Code website that I finally understood what he saw as game playing, could be turned into mathematical thinking and problem solving skills.   I told him that he could start teaching the class.  He was beyond ecstatic!  Within a day he created a Google Slide presentation and used morning meeting  time to teach my entire class how to code.

The students who are intrigued by learning how to code  have created a team.  They work together during recess to produce, collaborate, critique, and learn to create new code.  While some of their projects have focused on school topics such as simple machines and Ancient Greece, other games have been made for birthday presents, fun, and competition.  One of their recent games, “Wipeout” , was the featured game on the Scratch site receiving over 39,000 hits.

The Scratch team has presented at our talented and gifted committee and were invited as presenters to a local elementary school career day.  Together they ran four sessions to teach about 60 lower elementary children how to code.  The excitement we all felt was beyond words.  I know we are onto something here!  All it took was for one boy to “Scratch” the surface.

If At First You Don’t Succeed

I had no idea what I was doing.  There was no formal lesson plan, just a spark that had ignited a fire of self-directed learning.  The old question of, “how does this fit into curriculum?” came lurking through my mind.  Do I really have the time to set aside to help these children build a nameplate?  The pile of uncorrected work mounted on my table reiterated the negative thought pattern that was brewing within me.   Everyday they asked me if we could print their design until I finally caved in, took a deep breath, and learned how to import their design into Makerware.

It was time to hit print once again.  The build was to take over an hour.   The boys who created the nameplate gave up lunch and recess and we watched the printer build layer by layer.   We were in a state of disbelief as we saw letters begin to form.    We were confident that the build was going well.  I stepped out of the room, the boys left for another class, and I returned to a frozen Makerbot!

Ughhh! How could this have happened?  It must be the Makerbot’s fault, or so I thought.  I waited until the kids came back and broke the news that their design was not meant to be.  Problem solving was the furthest thing from my mind.  However, my kids knew better.  One of them came up with the idea to print a pre-made design again.    If it worked, it would prove the Makerbot was not the problem.  If it didn’t work, we had bigger issues.  The pre-fab design printed in perfect perfection.  The kids kept brainstorming and took a look at their design.  I started to look at what had happened too.  After 24 hours I realized that my computer had gone to sleep ending the communication to the printer.   Human error had caused the disruption.

The spark was ignited once again and we were all on board to go for the first real build…take 2.  This time we learned how to resize the design so that we could print a smaller version.  That way if it failed, it wouldn’t be long before we could find out why.  We had success.  My nameplate came out perfectly…mini-size.

The lesson I wanted my students to learn was how 3D printing software worked.  I guess sometimes the best lessons come from the unexpected.  We have all learned that we must  always remember to  try and try again!

Live in 3D


After 17 years of teaching, I feel like I am just beginning to find the surface of hidden potential within my students.  For years I have taught curriculum by making sure kids can understand math concepts, historical events, and more recently scientific theories.   I have taught life skills by helping kids to learn how to solve problems, get along with others, and the importance of kindness.  So why do I now feel like I have just arrived?  This year I see sparks!

I have entered another dimension of teaching I never thought possible.  Through Donorschoose.org I wrote a project to aquire a 3D printer.  I thought it would take months to fund this project.  However, within 6 days, the project was fully funded.  I had the printer two weeks later.  The excitement grew among my students as we stared at the unopened box.  I was afraid to begin.  The students asked me almost every hour about when we would open it.  It sat for days as an ominous threat to my teaching career.  What if I failed in front of my class?  What if I wasn’t capable of getting the $2400 gift to my class up and running? What if it broke?

With some soul searching I decided to grab the bull by the horns and go for it.  If I was to fail, I would use it as a “teachable moment” in learning from mistakes.  Together my kids took the printer out of the box,  set-it up, and rearranged my class to find the perfect spot.  A day later we hit “print” and we stared in wonderment as the printer hummed quietly and a comb appeared before our eyes.   We didn’t fail!!   We succeeded! Could we repeat it again?  We tried with another pre-designed item and a shark magically transformed from melted plastic.

That’s when it happened…there were sparks everywhere! I felt it in my heart.  I saw it in their eyes.  I heard it in their conversations. Suddenly the impossible dream, became a reality.  They knew they were into greatness and so did I.
