What Better Way to Spend A Friday Evening? – 3D Printer Building

Last week I missed the Saturday class and 4 hours of time to work on my 3D printer. Fortunately they offered some extra time Friday night to work. So about 6 of us showed up and spent 3 to 4 hours.

This all takes place in the University of Nevada, Reno, Engineering Design Lab.

 

 

 

 

Doug Taylor and I spread out all the parts from our 2 printers – still lots to assemble.

Slowly but surely the printers take shape.

As usual the laser cut wood that makes up the bulk of the pieces reeks of burned wood.

I add 2 more motors, (out of 5 total)  several belts and rollers that snap into their tracks and then make sure each part moves smoothly and easily. And when they don’t, adjustments are made and parts are taken apart and put back together correctly a few times (messy learning for sure).

The screen is attached and it starts to look more like a 3D printer.

This is where I ran out of time today, but back at it tomorrow. Lots of parts left to go, and based on others that are farther along … “lots of soldering … lots and lots of soldering.”

The prototype was running again today … mocking us it seemed. We’ll get there. 🙂

Update: Rethinking School District Social Media Policies for Teachers / Students

One of the challenges of my job as STEM Learning facilitator for 6 counties, has been that some of those counties (school districts here are by county, so every county is it’s own school district) have very restrictive online access policies … meaning they block almost anything even remotely social – blogs, wikis, photo archiving sites like Flickr and more. In one school district I was working with a group of teachers and pointed out that I’d found one of the above “not-blocked” – my mere mention of the fact was met with “SHHHH!” and,  “Don’t tell anyone! If they know its open they’ll block it!” But when I asked if that meant someone was using it they admitted that no they weren’t – for various reasons … none of them about educating children.

DSC00001.JPG

I just want to point out that the “T” in STEM stands for technology, and the real power of that technology is learning to learn, sharing learning, collaboration and more. The standards even demand that students collaborate globally, and as I point out often, I don’t think they mean by sending letters back and forth.

Back in November I wrote a post about this issue and asked for feedback on:  “What would be the most useful thing we could do to encourage district leaders to rethink their social media policies for teachers/students?” I received some great feedback in the comments section from some really smart people – check them out in the comments on that post. During a Twitter chat I even got a response from Arne Duncan, the US Secretary of Education asking for the names of the districts that blocked these sites. Although I did collaborate with folks from the USDOE after that, it was agreed that having Secretary Duncan contact these school districts directly was probably not the best course of action.

Instead we ramped up our campaign of information – both gathering information about what led the opposition to access, and disseminating information about safety and the reality of the various laws on internet and information use and access that many were misinterpreting to mean if they gave access to anything social on the internet they’d lose their e-rate funding.

In December I was invited to present to one district’s EdTech committee. I used a 2-pronged approach. I showed them numerous examples of the powerful use of these technologies and applications as learning places. Collaborative projects, how blogging can be used to motivate writing, editing, communicating, collaborating and more – wikis, video-conferencing, Google Docs and more – I have many examples right from my own classroom, but also with the many teachers and students my classes collaborated with over the years.

Next I pointed out the realities from laws designed to keep students safe online (the ones that lead folks to believe they’ll lose their e-rate funding and be sued). I was able to use numerous sources to point out that the law, in a nutshell, states that you must basically show that you are trying hard to keep students safe, if something then goes wrong you are OK (slightly more complicated than that).

The good news is, that that school district has “green lighted” a pilot program of blogging in one of their elementary schools with 4th graders. Tomorrow I meet with the teachers at the school to get their blogs set up and a bit of training … then Tuesday I’m back all day to get each class started to blog and post a few times to get the process down as a first step. I noted last week while visiting the school that wikis are now unblocked and even Flickr (but almost no one uses them yet or even realizes that they are unblocked), so we have a foot in the door!

I’m not nervous at all to work with the teachers tomorrow, but I don’t get to work with students more than a handful of times a year anymore, and so I can tell I have that combination of being both excited and nervous about being in a classroom … like the first day of school feeling. I’ll keep you updated.

I’m Building a 3D Printer – Day 2

A few days ago I posted about being part of a class for teachers and educators where we build a 3D printer and learn to use it and the keep it to use with our students and teachers.

Today we were given the entire 3-4 hours to just get back to work assembling our printers. The group all retrieved their boxed printers and got to it.

BELOW: What I got done the 1st week:

IMG_1859

 

 

 

 

 

 

 

BELOW: Most of what still needs to be assembled.

IMG_1861

 

 

 

 

 

 

 

This printer is mostly made from wood. Wood that has been laser cut into parts … VERY precisely. The burning involved in laser cutting is betrayed by the black edges of the parts as you break them apart during assembly, as well as a hint of burning wood in the room and our somewhat blackened fingertips. Lots of screws and nuts, washers, gears and more are involved.

IMG_1864

 

 

 

 

 

 

 

We got to a certain point today and the next step meant we had to get the 5 electric motors required:

IMG_1865

 

 

 

 

As we assembled the frame, which involved installing the first motor, the shape of the printer emerged.

IMG_1867

 

 

 

 

 

 

 

 

 

 

When we ran out of time today we had a few more parts assembled and ready to add.

IMG_1869

 

 

 

 

 

 

 

 

By that point we had also installed the second motor.

IMG_1870

 

 

 

 

As pieces are snapped out of the laser cut wood lots of these little pieces fall out … are they all unnecessary? Or ??? Deciding keeps you on your toes.

 

That’s as far as we got today and it might be 2 weeks before I get a chance to work on it some more. We’re told it could be 20 hours of work when tweaking all the settings and getting software setup and all … after today we were about 7 hours in.

BELOW: The printer they assembled to check out the assembly process was busy today printing out gears for a transmission (note the image on the computer):

On The Road – Project Wet Training

logo

One of the valuable STEM learning opportunities I’m part of right now is training teachers across our state in Project Wet. Think of it as Project Wet with a STEM focus.

We wrote and received a rather large grant sponsored by the Nevada Division of Environmental Protection (NDEP). Its enough money that we will be conducting these trainings for about 2 years with the goal of training hundreds of educators statewide in water and other science content.

Myself (I’m the STEM Learning Facilitator for northwest Nevada), Lou Loftin who is the Science Learning Facilitator, and Mary Kay Wagner an Environmental Scientist in the Bureau of Water Quality Planning with NDEP, are a team that travels around providing 16 hour trainings statewide. Nevada is a huge state (from here in Reno to Las Vegas is over 400 miles one way) so we put many miles on Lou’s truck which we cram full of equipment and supplies when we go on the road.

Currently we are in the middle of a 4 session class that convenes just south of here at River Fork Ranch in Genoa, Nevada.

We combine lessons right out of the Project Wet Guide 2.0 (which you cannot buy – you must participate in a least 6 hours of training in Project Wet to receive a guide) with hikes through the parks where our classes usually take place, some training in online photo archiving (Flickr), wikis and the online Project Wet Educator’s Portal.

Besides receiving a copy of the Project Wet guide, participants in our trainings also take supplies and resources provided by the grant back to their classrooms – beakers, pipettes, graduated cylinders, measuring tapes, Earth globes, maps and more. They also take back the links and online resources we help them register for (see above) and the network of teachers they meet and link to as part of the class. Several participating teachers have already brought their own students to the sites on field trips.

If you follow me on Twitter I often Tweet out photos and reports of where we are and what we’re up to. We have several more “Wet” classes coming up before June in eastern Nevada, and come fall we’ll continue our treks around the state. One of the “perks” of a project like this is getting to visit the beautiful places that abound in Nevada.

BELOW: Photos from our training in Las Vegas at the Clark County Wetlands where they pump 3 million gallons of water from the water treatment facility through the park daily to help provide habitat for a surprising amount of flora and fauna in the desert.

Building My Own 3D Printer

A few weeks back I was invited to participate in a class at the University of Nevada, Reno, where participants would build a 3D printer from a kit and learn how to use it. I jumped at the chance since you get to keep the printer, and I saw the possibilities to take it with me on the road as I travel throughout the rather large region I cover as STEM Learning Facilitator in northwest Nevada.

IMG_1842

 

 

 

 

 

 

The class is being taught by the same mechanical engineering folks that facilitate our high altitude balloon launches (see the TEDxDenverEd video in the right margin of this blog). My colleague Doug Taylor who taught with me for years when we collaborated on those launches and much more is taking the class with me and is building his own 3D printer.

I do not have much of a background in programming unless you count a bit of BASIC I learned 30 years ago or the LOGO I dabbled in with students, so I see this as stretching me a bit as well as providing another resource for the school districts I serve.

IMG_1843

 

 

 

 

 

 

 

 

After presenting us with some background on advanced manufacturing we were put into pairs since 2 printers came in each box, and put to work putting them together. The directions are YouTube videos and PDF files you are linked to –  which is a nice combination.

IMG_1844

 

 

 

 

 

 

 

You can see they crammed 2 printers in each box and there are numerous parts and many are very small. The tools are Allen wrenches, screwdrivers and pliers.

IMG_1845

 

ABOVE: Everything required to build 2 printers.

BELOW: A finished printer printing gears. This is the instructors’ practice printer – they figured they better go through the process of building one themselves. The printing material is blue plastic – reminds me of the line you use in a yard trimmer, but a bit thicker. You can see the blue spool of material in the upper left of the photo.

These are MakerFarm Prusa 8″ i3 3D Printers – about $600

Learning Is Messy!

 

Rethinking School District Social Media Policies for Teachers / Students

I’ve been fortunate enough to teach in a school district that blocks very little – blogs, Twitter, Flickr, wiki’s, YouTube, Cover-It-Live, and more are all open. FaceBook and the obvious porn and other sites are blocked. However in my job as STEM Facilitator I hear from teachers locally and nationally in school districts that block most to all the above and more. If there are any social possibilities, whether it is moderated or not … it’s BLOCKED, no questions or comments allowed.

I’ve also been asked to share with local, state and even the US Department of Education, “What would be the most useful thing we could do to encourage district leaders to rethink their social media policies for teachers/students?”

So for everyones benefit it would be more than helpful to get feedback about that here. Especially if you are an administrator or government representative that has successfully dealt with this issue. The Common Core State Standards require students to collaborate globally, and certainly many of us can sing the praises as to why and how that is a valuable learning experience. So again – What would be the most useful thing we could do to encourage district leaders to rethink their social media policies for teachers/students? PLEASE share in comments and I will pass on.

Thanks in advance!

Unleash the Learning Power of Blogs By Actually Using Them Consistently!

Blogs are an incredible learning tool. But like an exercise bike, having one does not lead to self improvement unless you use it. And using it sporadically is only barely helpful. You have to invest time to get the great results … imagine now the sculpted/toned bodies of the models they use in ads for any exercise equipment … then imagine the sculpted/toned brains of your students using blogs. That doesn’t happen without consistent use.

Now that I think of it though, blogs are not like an exercise bike, blogs are like one of those pieces of fitness equipment that include multiple exercises – weight lifting, sit-ups, pull-ups, leg lifts and so on. Blogs are certainly writing spaces, but they lend themselves to not just publishing writing, but also response and discussion which is that higher level thinking we are vying for. But wait! There’s still more. Blogs also include, publishing photos, videos, podcasts, spreadsheets, slide shows, art work, and much more. AND all of those pieces can be written about and discussed. AND note its not even all writing, notice in my partial list it can be oral language and media … and of course it involves reading. So multiple exercises for the brain! AND all of that is archived and it is then easy to see improvement over time – you can see it, your students can see it and their parents can see it.

Did I mention the family connection? Not only is the blog available for student collaborators to see and interact with, the students’ families can as well. Students can go home and show parents what they did today, family members can comment … see what I mean? Oooh, and I’ve had experts like scientists and athletes and the like leave comments and interact as well.

Here’s the thing though, getting back to my initial point, that doesn’t happen if we don’t use them consistently. Blogs are powerful, engaging, motivating, learning tools. So use them consistently, and use all their possibilities. Otherwise it is like doing one or two writing projects a year that you turn into published books … “My Poetry Book” and/or “The Day I Was My Dog” – great stuff, but imagine doing that all the time and you (the teacher) doesn’t have to find the special paper and laminate and so forth.

Oh, and couple your class blog with a wiki and a photo sharing service like Flickr … it only gets better.

So if you have your students blogging because you want them to learn. Then really have them blogging all the time!!!! The initial time it takes to get them up and going will pay big dividends!

Sharing Real-World Projects Sharpens the Literacy Skills of Connected Students

I have a new post up over at the Powerful Learning Practice Blog entitled: Sharing Real-World Projects Sharpens the Literacy Skills of Connected Students. Head over and give it a read … and comment as well. 🙂

I’ve been making the point in my STEM trainings that part of the appeal, to me at least, of STEM and Maker learning, is how language intense it should be. Teachers react well when I point that out and make the case for not leaving the language experiences “on the cutting room floor,” so to speak. There are so many deep, thoughtful, and especially, creative language possibilities that are too often not realized or wasted in the rush to do an interesting, engaging activity and then move on.

Learning is messy!

A Professional Learning Community/Network Example

Or: “Why many educators find Twitter and other social networks indispensable.”

I’m currently attending the NSTA STEM Forum and Expo in St. Louis. Last night while taking a class on using telescopes in the classroom,  not far from my house in Nevada I got an email request from a teacher wanting to know if there was a way to live stream from her classroom so that the chicken eggs her class is observing could be watched all night so as to not miss their hatching.

I thought of USTREAM, but I haven’t had reason to use it in awhile and when I checked it out I could see it wasn’t going to meet her needs. So I went to Twitter to see if the network of educators and various “techies” and others I’ve been fortunate to be part of could help:

My Twitter Request

 

 

 

About 5 or so minutes went by and lo and behold Chris Craft from South Carolina chimed in. He suggested using Google Hangout … then when I balked somewhat, he filled me in as to why it should work:

Chris Craft Twitter

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(Note my typo in the last Tweet – it should say “so I’ll have…” not si)

In the meantime I touched base with the teacher that requested the help and set up a time next week when we will try to make this work (or a variation of it) well in advance so we have time to problem solve. I’m not positive it will work (at least in part due to limitations on my part) but it gives us a solid place to start and a resource (Chris) I can go back to for clarification if we do run into issues.

I lament all the time along with many of my colleagues that we don’t share these examples of how a PLN helps … is really indispensable anymore. So when this happened I made sure to share … but there are many examples and it is hard to always share. Hope that helps clarify PLN’s a bit more.

Oh! And I’ll do my best to share how it goes!

STEM-ing the Tide of Education Reform

NOTE: This post was originally published at the Voices from the learning revolution blog.

“Everybody in this room understands that our nation’s success depends on strengthening America’s role as the world’s engine of discovery and innovation. And that leadership tomorrow depends on how we educate our students today—especially in science, technology, engineering, and math.” (STEM)

President Obama to a gathering of CEOs, scientists, teachers, and others. September 16, 2010

STEM is the new education buzz-word, even the president has been talking it up.

I’d have to confess though that this attention also worries me. I’ve been to conferences where everything on the vendor floor displays a sticker announcing how — whatever it is — it’s “aligned to the Common Core State Standards and STEM!” I’ve even visited a school that claims it is a “STEM Academy” because (it brags) teachers are mandated to do at least 15 minutes of science EACH DAY!

If any of this sounds familiar, it’s the same approach and attitude that led to technology getting a shady reputation in education. Another “big idea” that is inevitably reduced to a subject or activity — something teachers must spend another chunk of precious class time on. It’s typical education “reform.” Instead, what we need to do is transform. STEM, done right, can help make that happen.

STEM (Science, Technology, Engineering and Mathematics) is not a separate subject, and you don’t “do” STEM just by doing any one of its pieces. One of the reasons I took my current position was that I recognized that STEM education has promise in leading us away from each subject only having a singular focus — its own chunk of time in the schedule. STEM demands that we teach lessons and pursue projects that connect all the subjects represented in its acronym. In this day of narrowed curriculum, that is a very important distinction!

The STEM connection
So how does STEM education differ, and what does it have to do with connected learning? One way to think about STEM is in the context of that desirable learning strategy we hear about now and again: “taking the time to go deep.” One of the big complaints about NCLB “reform” has been the narrow “surface” learning its accountability mechanisms have produced as a by-product. STEM provides in-depth experiences that students share and can therefore discuss, explain and argue about.

A STEM unit often starts off with a science activity that introduces the concept and leads to the initial research. Besides library books and internet searches, that research should now include communicating with experts. Email, blogs, chats, video-conferencing and other social networking tools and strategies not only add to the learning by involving advisors and collaborators, but teach students how being connected should be part of their learning process.

In addition, a true STEM experience involves the “E” – Engineering. Students should be building something or improving a design. Solving a problem through building and improving involves trials and testing things out, in other words, collecting data, the “M” or math component of STEM. By analyzing performance data, students can make adjustments to their design — quantifying what is really best or most efficient.

Students working in small groups will learn as they note differences in design and efficiency between their creation and those of other groups in the room. And we can up the “connected learning” factor by having them partner with peers beyond the room — students anywhere in the world who are working on the same or a similar activity.

Taking it one step further: what if the groups our students are working in include students in other locations? What if the groups in my class in Nevada have virtual members who are in British Columbia or Scotland or India?

Now the challenge of STEM collaboration takes on new dimensions … staying in communication across time zones, being responsible for getting your part done, being able to share your learning in a way that is understandable to students in different contexts and cultures. Will connected teams use blogs? wikis? email? Google groups? Dropbox? Live meeting spaces? Weighing the advantages and disadvantages of various combinations of virtual partnering is all part of the learning.

Now imagine connecting with an expert in the field you are working in… asking questions, sharing insights, getting tips on design, learning from their experience. All this connectedness can be a huge asset; done well, it can become a vital and very “sticky” part of the learning.

Expanding STEM across the curriculum
As the overall project continues, the potential connections afford many opportunities to vocalize and clarify thinking, as well as the motivation to do quality work because you have authentic audiences. The writing and communications work should also be deep. This can involve creative writing and sharing experiences through stories, poetry, music, video, art of various kinds (STEAM!), and more.

Blending STEM with “connected classroom” strategies is a powerful learning model — a highly active learning model. For this to work well in schools, however, we have to have innovative thinking, teacher autonomy and flexibility in scheduling. These essential components of “going deep” with teaching and learning have been eroded away in the last decade. If we are truly going to integrate and embrace STEM education and innovation, we will have to revive them.

The possibilities of authentic, globally connected STEM projects that flatten curriculum walls, engage students through curiosity, and ignite their natural desire to solve challenging, worthwhile problems is why I am personally promoting the STEM concept. I see it as a way to bypass the most misguided aspects of current “reform” movements while promoting — even requiring — critical and creative thinking and true innovation.
