A Little Bit of Cross Campus Collaboration

Over the last few weeks, I have been privileged to have the opportunity to do some collaborative learning with our local Secondary School - Ormiston Senior College (OSC). One of the teachers there, Mr Chandar K, has been using the Sphero robot in his teaching and had heard that we were using them as well in the primary school. He contacted us and offered to take a small group of our learners and do some activities with them, to teach them how to code the Sphero Robots.

I've had a couple of Spheros (and two Ollies) and have been letting our learners use these all year, but I wanted to learn how I could use these a bit more. We were a bit limited by our small numbers, so the opportunity to use 8-10 of them in another setting was very enticing. We asked the 90 learners in our habitat which were interested and got 18 who were keen to make the once weekly trek through the Junior College to go learn about how to code a robot.

For the past month or so, we've been learning and developing our coding capabilities and I've been getting lots of ideas as to how you can manage a robotics curriculum in a school.

On the teaching side of things, Mr Chandar K started by letting the learners free drive with the sphero. This was the last time he let them do this. We had a couple of races to get them used to how the sphero moves and what it is capable of doing.

From there we did some simple coding - making the Sphero roll for a short amount of time, at a specific speed in a specific direction.

That was the end of week one. When we came back the next week, we tried another challenge: to make the robots go in a square (and then back again). This proved difficult for some learners as they had to change the directions (so we learned a bit about angles), and adjust the speed or time so that the sphero would go the correct distance. Some were able to complete the task AND make the robot retrace its steps.

The third session involved our learners trying to program the sphero around three objects inside a square - so essentially they had to program a triangle. This was also difficult, but many managed to do it.

Our most recent session involved the learners coding the sphero to go in an L Shape on the carpet. We had some difficulties today and discussed concepts like friction (the carpet was pretty bumpy itself, but the little markers used for the shape were slowing the sphero down a bit and knocking it off course) and fractions, ratios & proportions (when trying to adjust the distance the sphero would go). As a learning coach, I am starting to see a lot of the mathematical applications with using a sphero.

As you can also find out in the video, we learned about putting a delay between roll blocks so that the sphero goes in straight lines, instead of curved.

So why was this helpful? Well, just on the surface this was great for my learners because they got to experience these robots and learn in ways that we cannot yet provide (with only my two personal sphero at our school) and I was given a great starting point for what I can do with them and lots of ideas as to where we can take this.  But there are deeper implications from this experience. At Ormiston (and I mean the three schools combined) we have a great opportunity for some great collaboration between all people (leadership, learning coaches and learners) and this was a great example of what could be done. I know Mr Chandar K is also working with the Junior College. This will hopefully provide future opportunities for the adults at the three schools to sit down and figure out what we want to teach when it comes to robotics and to start to share knowledge and resources.

As for next steps in the coding, I'd like to start introducing some looping functions and then eventually if statements. There is a lot that can be explored in this coding and the doors are starting to get a bit wider for me.

If anyone out there has any other innovative ways to use these robots, please share in the comments!

Exploring Literacy and Coding

A while ago, I participated in a wonderful Twitter chat with #digitaledchat where we discussed what you could do with robots in class, such as Sphero. One of the things that came up was using them to create stories or videos by coding the robots as characters. I liked that idea so much, it got me to thinking quite a bit about how coding and literacy could be combined.

I've tried really hard to make my class a creative one, in which my learners are able to explore different ways of learning that are fun, creative and exciting. I want the children in my charge to wake up in the morning, excited to come to school and do their work (which they won't see as work). I have had many different ways of making stories and being creative (including Stop Motion and Digital Storybooks) so it wasn't a big step to try some new things. Here are three ways in which my learners used coding or computational thinking to create stories:

Choose Your Own Adventure Stories Using Google Forms

Many of us have read these books as children and this idea is definitely not a new one. You can use the "go to page based on answer" feature of multiple choice questions to direct readers to new pages based on their choices. When we first did this, I used Google Drawings to plan out the story (it can get very complicated if you have a lot of choices) but it isn't always necessary. A pair of my learners created this story earlier this year.

There are other ways of making stories like this, including Scratch.

Stories on Scratch

This idea came from CS-First.com where you can find a whole 8 lesson module on coding stories for code clubs, though if anyone has used Scratch Jr, that's basically what that app is for. The idea is simple: code the sprites to speak to each other and interact. As coding knowledge increases, so too does the complexity of the stories. This is definitely an area to explore for reluctant writers who happen to like coding (and I've noticed the majority of my learners are liking coding more and more everyday, some even attempting to code a Choose Your Own Adventure story).

Coding Robots to Tell a Story

This was the big idea from #digitaledchat that I have been waiting a while to try. We only have made one attempt at this, but it went, in my opinion really well. Some interested children joined me for a short brainstorming session. We came up with some characters and starting thinking about what their story was going to be about. Some other learners got interested and joined us at this point and the discussion started taking off. I backed off and let them sort things out. There were varying levels of coding abilities in the group and they were able to support each other. A lot of the story didn't really utilize coding knowledge, but it was a fantastic start. Again though, a little disappointed that these children won't get to try this again with me, but I'll keep on introducing these ideas to children and see how they develop.

The plan with this topic is to continue to explore it further, get children making more and more stories using their coding skills and then to share this in more depth next year (hopefully at GAFE & ISTE). So keep an eye out if you're interested as I think this is an exciting way to develop a plethora of skills amongst learners.

TAP Lab Visit #3

This Wednesday I returned to the TAP Lab to continue my education in all things Maker. Most of this involves Arduino and other types of coding, but we'll see where things take me and how much time I'll actually have in the future to come back (it is pretty far away - but definitely worth it).

Today's session started with me figuring out another sensor - a temperature sensor which is surprisingly accurate. Then the very helpful people at the lab started telling me all about all the parts I had in my Arduino kit, including some displays. Well, I was intrigued. My big thought was to get the display to show the temperature. Well, it was a massive job just to 1) figure out how to hook up the display to the Arduino board and then 2) figuring out the coding, which had a very simple, but inexplicable error.

The code we found on the Internet for the lights was giving some really strange results. We poured through it, trying to figure out what went wrong. Then we started testing things to see what changed. It became apparent, at one point, that the lights were doing the opposite of what they were meant to do in the code. So, I changed all the 'trues' (which the code said meant the lights would go off) to 'falses' and amazingly, the display lit up as it should have. It was a good lesson in debugging, though it got pretty frustrating at one point, and I was definitely in the dip (growth mindset FTW!). But this only led to a static display. I managed to change the display to my birth year and then discussed ways in which I could program the numbers to change - though due to the tediousness of the code I'd have to write, I put that off for another day.

Learned how to code a 4digit display today at @TAPLabMakers Next step: make numbers change! #MakerEdNZ #hacksterlive pic.twitter.com/KkrINLhHb2

— Michael Davidson (@michaelteacher) August 31, 2016

Since I remembered to bring my mBot to the lab, I decided to have some fun with its display as well. It is much easier to program the lights there (it's all visual, and you just need to click on the squares), so I was able to spell out all the number words to ten and get it to count up. I bet I can modify this program to make it do addition or subtraction (or many other things). Hmmmmm.... I do love how learning one skill can get you thinking about how it can be applied. Have a look at the video of the lights changing.

Today was a fantastic lesson in what actually goes on in a makerspace. It was often quiet when I was working, but when I had a problem, many people there were willing and even eager to help me. That's the kind of atmosphere I'd like to create for makerspaces. I spent two hours there, but it felt like 10 minutes. Again, that's what I want for MakerEdNZ. 

TAP Lab Visit #2

Once again, this past Wednesday I made my out to Te Atatu Peninsula Makerspace for their weekly meetup. I wanted to a) learn more about using Arduino (specifically sensors), b) potentially figure out what's wrong with my mBot and c) continue to build a relationship with people who actual know how to run and organize a makerspace so that I have some real-world experts to help with MakerEdNZ.

Overall it was a pretty good evening. Though the weather was bad there were a good number of people who could help me figure some things out. It was nice being in a room of problem solvers - people who will try different things to figure stuff out. With some help I set up a photoresistor sensor on the Arduino board to check for light. We had a good discussion on what the results actually meant (I was getting high numbers when it was dark and low numbers when it was light, which was confusing to me).

The subject of my non-working mBot came up as well. Another person there helped me use their mBot to try connecting it via the 2.4GHZ connection. It worked reasonably well and I was able to explore a little bit about the sensors on the mBot. It was good because while I was doing so, I was able to imagine in my head how these lessons and ideas could be put to use in a classroom or makerspace (and now I have some skills to work with as well).  The unfortunate part was that when I went to school the next day, I was unable to get the mBot working completely, so there must be some other issue. So there will be a visit #3 coming up soon (I've signed up to go next week and the week after, but we'll see if I can actually make those days). 

Anyone interested in makerspaces or joining us for #MakerEdNZ, I'd suggest visiting a community makerspace and see what they do. Everyone I've met has been very friendly and extremely willing to help. You can find lots of those on Meetup.

ISTE 2016!

It has taken me a few weeks (almost a month, in fact) to fully come to grips with my ISTE 2016 experience. To sum it up in word: Amazing! But obviously there were some really good takeaways that came from the experience. I'll try my best to share all of what I learned, but no doubt some good stuff will get left out.

edit: Now it's almost two whole months after ISTE! But still thinking lots about it. Some of this may be repetitive because of the time between when I started writing and when I finished, but I think the tone that will likely be consistent throughout will convince you of the value this experience had for me and could have for you in the future.

People, People, People

The first place you need to start when dealing with ISTE is the people. I'm not talking about the sheer number (though that is staggering on its own). What I'm talking about is the people you meet. The biggest draw for something like ISTE is to meet lots and lots of like-minded and incredible people. And don't get me wrong, EVERYONE at ISTE is incredible. When I told one of the people I met that "I'm just a classroom teacher," she responded by saying that nobody is "Just" anything. We all have something to offer, no matter the title or experience. Though I did realize this before, it was interesting to see how our language can affect our perceptions (and the perceptions we create in others). Later on that day, I met someone who said pretty much the same thing about being "just" something. I was spurred on to share my new perspective.

There are also countless opportunities to meet and connect with educators around the world (well, mostly the US). There is so much value in this for all of us and our students who will benefit from these connections. I made a concerted and deliberate effort to seek out new people and talk to some who I wouldn't have otherwise spoken with - including the CEO of ISTE! I made several great connections which will help me make further connections in the future. It's all about the people. If that were the only result of the week in Denver it would have been worth it completely.

On top of meeting people at official conference events (probably the best source of that was the Global Ed Day - a great group of people to connect with, if you're looking), there were several social events which turned out to be just as valuable. I had made it my mission to find the "seedy underbelly of ISTE" this year, and while it definitely wasn't seedy, it made the conference that much more impactful. My only regret is that I didn't find more events to go to. In all, I attended events put on by Wonder Workshop (happy hour at a restaurant), the Ed Tech Team & Symbaloo (Karaoke), Gaggle (a party) and OSMO (a Sneak Peak event). All of those events, helping to strengthen my PLN (personal learning network for the uninitiated). I was able to build on some of the connections I made a year prior and hopefully will be able to build on these ones in 2017 (because yes, I'm going).

New Things and Old Things with More Pizazz

Having been at ISTE last year, I found that there were a lot of things repeated, but with more development. There were literally tons of resources (if you weighed them all together, there is no doubt of this) showing how makerspaces and making can be used in the classroom. Many people were sharing how they've been using their robots (many of which I bought last year after ISTE) and other cool gadgets in the classroom. For example, there were many people sharing what they've done with paper circuits (a shout out to Chibitronics & Spark Fun who both gave me some free samples to use in my classroom) as well as robots (guess who won a free kit from Hummingbird?) One really cool startup that was sharing in the expo was Hyperduino which had some really simple applications with their custom built arduino boards. They ran out of free samples by the time I got to their booth, but I may pony up the dough to get one.

It seemed like everyone had a Dash & Dot, Sphero & Ollie and Ozobots. Not to mention Makersaces. Perhaps this, too, was one of my big takeaways from the conference, and (since it's taking me forever to write this reflection) one of the things I've been most active promoting since I've returned. While I'm fully trying to gear up my classroom's Makerspace, ISTE this year has planted the seed of a big idea in my head. I'm working now to start #MakerEdNZ, a community of schools and teachers who are using Makerspaces in their classrooms. I'll write a long post about it later, but for now, just know that ISTE inspired me.

Global Connections

The only actual planned event I went to at ISTE was the Global Ed Day 2016. What a great group of people. Again, this is something I want to explore in much greater detail. Yes, we've done Twitter chats and Mystery Hangouts, but those connections are only on the surface (but again, much, much better than no connections at all). A lot of the talk around the Global Ed Day was starting collaborative projects between schools on different continents. This is another area for leadership within New Zealand, I feel, and something that is many people are primed for. We'll see what comes out of this, but perhaps someone reading this will take the call to arms and run with it. I only ask that you please include me.

Things I've Been Using

So it has taken me 2 months to get this far in my reflection. But that provides a great opportunity to reflect upon how those new things are going. Probably the most immediate thing I tried was Seesaw. For anyone who hasn't heard of this before, I urge you to have a look at it. I was lucky enough to have it explained to me by a teacher at the Seesaw booth in the expo. It's basically like Facebook for schools. Using the app (on tablets, phones or chromebooks) my students can take pictures or videos of their work, record an explanation over top of it, tag themselves in it and just generally share their amazing ideas. They can like each others' work and make comments - both written and oral! And I've only scratched the surface of what I can do with it. So far my students have found it super easy and have enjoyed sharing.

I also re-met my good friends at Kiva, which got me back to teaching the Kiva U curriculum (in the small amount of time that I can fit it in).'

I've also given my students focus with the Student Blogging Challenge. Though we may have been a few months late, meeting some of the people who have set this up, got me intrigued. My students have had some ups and downs with it (some of them spent a whole week or writing time making an avatar, not saving it, then making a new one), but overall it has helped teach them about blogging a bit more.

Another, practical thing I saw at ISTE and brought back to use were all the paper circuits that were being shown. I was extremely lucky to have been given those starter kits from Chibitronics AND Sparkfun, so I had a go with that at school AND at some educamps. It was interesting to say the least and something I want to look more into.  I was also given the chance to make a wearable circuit with some Lilypad Arduino components:

One of the sessions I went to was actually done as a walk around Downtown Denver. The presenter was telling us that we should be getting our students more active in class, and building movement into every activity. I had previously had swiss balls in my class but had given them up because of some behaviour issues. However, he inspired me to pump them back up and get my students moving more often. A small thing, but I think it's something that's important.

Conclusions

I could go on for pages and pages talking about how ISTE has changed me and my practice, but my biggest advice is: Go next year to San Antonio! It will change so many things about how you see teaching and give you so many ideas to help you do so. It will give you connections that will change your idea of teacher-teacher relationships and the way our profession should interact. It was honestly the best four days of the last year for me. Unlike a lot of the New Zealand based conferences that I've been to, ISTE has made me feel that we lone nuts are much stronger in numbers. It's nice to have our smallish group here, but expanding beyond our shores, in my opinion, is never a bad thing. Being part of something so big, is truly empowering. Meeting so many genuine people who only want the best for their students is inspiring. So, I urge all of you Kiwi teachers (and why not all my Canadian teacher friends as well, I belong to two countries), come with me next year! Come join my tribe!

Educamp Auckland

This past Saturday, I attended Educamp Auckland at Aorere College. I was quite nervous because, though I had attended two Educamps previously, this was the first I was going to stand up and share (though, I guess I did share at Sparkshop, but that was slightly different).

The nervousness turned out to be unnecessary, as everyone was amazingly supportive of me and what I was sharing. I guess I have become accustomed to people shooting me down and trying to get me to stop sharing.

I ended up having two sessions out of the three, which was good, but it also meant that I missed out on what a lot of other people were sharing. Though, the conversations are the best part (for me, at least) and I had lots of those.

It was also the first time where I publicly talked about my pet project: #MakerEdNZ. No doubt I will be sharing more of this along the journey, but suffice it to say, I was also overwhelmed by the support I got from many of my twitter friends (I guess they are real-life friends now). If anyone is interested in what this might be (i.e. if you know or want to know about makerspaces) please follow @MakerEdNZ on twitter (or me) and information will be coming out soonish (and probably another post on here as well - when I get caught up).

I did get a number of takeaways from the unconference. The first is (and I can't say it's the first time I've realized this) that I can easily go a bit too fast when sharing what I know. This is something for me to work on (but hey, I'll likely get a chance each of the next three weekends, so there's that).

I also have a few twitter chats planned with other people. It's amazing how quickly things can happen when you're in the right company. I'm excited and a bit nervous for this, but looking forward to both of those opportunities.

It was also a really great experience (going back to #MakerEdNZ) to give others a chance to spend some time doing some STEAM activities. I brought some copper tape, LEDs and batteries to make paper circuits. This is part of what I want Maker Ed NZ to be doing, so it was a good first step (though I wish I would have gotten some more pictures for the twitter account.

If anyone reading this has never heard of an educamp, I strongly urge you to go to one (educampBOP is this weekend). Thanks to Jackie Allen and Stuart Kelly for all their organization of the day. Was definitely a positive way to spend my Saturday!

GEGNZ Sparkshop!

This past Saturday, I attended the first (I think) ever GEGNZ Sparkshop at Ormiston Primary School. Over the last few weeks and months, I've slowly started becoming someone who shares a lot, and it seemed like a good idea to come to this prepared to share.

Smorgasbord
The conference (or rather, unconference) started with a smorgasbord of ideas that people voted on. I put two ideas in. The first was sharing mystery hangouts (or skypes, depending on where your loyalty lies) by myself. The second was a collaboration with Angela Lee on makerspaces and robots.

I was pretty much the first person to share and it was quite nerve-racking to go up first, especially since I was trying to sell what I was sharing. I spoke quickly and tried not to be too imposing. I think I do give off a very nervous air, but that's ok.  It was then a lot of sitting and listening to other people share their ideas before we voted.

When all was said and done, both of my ideas were booked into places to share. I figured they might be. I'm not being full of myself, but they were interesting things. Luckily I was in the last two sessions, so I had a chance to go check out another session while I fretted away.

Forms (Sarah Allen, from Riverhills)

My one and only session that I participated in the audience was based around using Google Forms. This is something that I've done a lot lately, so I figured I might get some new pointers (there's always something new to learn) or at the very minimum be able to contribute something.

Among other new ideas, we were introduced to Poll Everywhere, a very quick way to get feedback from students and to get them to share. Like other tools (padlet comes to mind) it has some specific uses, but it was also extremely useful in that it can embed into slides (unlike so many other things).

We discussed reasons for gathering student voice (none of which were really earth shattering, but it's important to note that I do think it's important for a variety of reasons - I wouldn't be focusing changing my practice towards increasing this if I didn't), and also wondered whether or not Kahoot! can do similar things (I'm going to try this at some point in the near future).

We discussed various other uses of forms and some add-ons to use. I particularly liked the add-ons Choice Eliminator and Email Confirmation (it may be called something else).

A random idea that came up in the discussion (I actually brought it up) was to use a form to make a choose your own adventure story. I actually got so excited about this that on Sunday I went home and started making an example so we can do it as a class in the upcoming weeks. Hopefully I'll be able to write about that.

MakerSpaces

Next up was my joint presentation with Angela. We shared a few makerspace ideas, but in the end, it was the robots that were the most popular. Several other attendees loved playing with my Dash and Dot (I may, in fact, be one of the only - if not the only - classrooms in New Zealand that have these robots). I think Wonder Workshop may owe me a bit because I'm pretty sure I've convinced some people to buy them. I'd like some more myself.

We did have a lot more out - Squishy Circuits and Makey Makeys. The circuits got some attention, but I was naturally drawn to the robots and I think a lot of people followed me. I guess people can easily get overwhelmed.

Mystery Hangouts

The crowd for my second presentation was much smaller (6 people) but it was nice to have an intimate setting. I briefly talked about how a mystery hangout works and then we practiced it. I quite enjoyed watching adults have a go at figuring out different strategies for guessing. I think I sold the idea to them though as at least one had already booked a call for the week coming up!

Here's the slideshow I shared during that presentation (in case anyone else wants to try it).

All in all it was a good day. I had lots of interesting conversations about coding and got to know some more people (though to be honest, it's getting to the point where a lot of people know and remember me, but I can't remember them - at least I'm pretty good with faces, but it could make for an awkward meeting in the future. If you're reading this, I have't forgotten you on purpose, I'm sorry).

I do enjoy this presenting thing, though I do sometimes feel like I don't actually know what I'm talking about (ok, I don't actually know) but I think that's part of it. I don't ever want to feel like the expert, but rather I want to constantly be learning an improving.

That being said, apparently I've been included on a proposal for part of the pre-conference things (I think?) at ULearn this year. Should be fun.

Educamp Science

Introduction
This Saturday morning, I woke up early to run so that I could go to the first Educamp Science unconference. Luckily for me, it was local, so I was able to enjoy the sunshine before the conference. Having been a chemistry major before I went into education, science has always been something I enjoy. I got to meet several of my twitter friends early in the day and there were lots of choices for breakout sessions.

Data Logging with Stuart Hale
The first breakout session I went to was about Data Logging. The first bit of the talk was about using pictures, since they are a large part of collecting data in science. Stuart showed us how to share between devices when no wifi is available (through airplay on the iPads) as well as showing us how you can use a loupe (a magnifying glass for jewellers, if I'm not mistaken) to make a really cheap digital microscope. In fact, I was able to find loupes online for even less than what he shared. All you need beyond that is some blue tack.

Another neat thing he showed us with the iPads is to use the built in Time Lapse feature on the camera app. You can put it on things, such as leaves, construction sites (I'm trying that now in class, with the builders behind our room), tides, etc to see how things change over time.  He suggested putting a sticker in the corner of the iPad where the camera is, to help children who might put their finger in front of the lens.

Digital Microscope with Wooden Blocks as a Stand

He then went on to show us some really cool things that iPads can do. Most iPads have the ability to measure things such as vibrations (a seisometer), magnetism (telsameter) and acceleration (accelerometer). These things can be use to make graphs and conduct scientific investigations (he used an iPad to test what makes a bike ride smoother as well as to see how to make sturdy buildings).

On top of that, there are loads of sensors that can be purchased (temperature, movement, etc) that can be used to make graphs. PASCO was the company he suggested, though I imagine, a quick internet search will provide other, cheaper options.

Fischertechnik Makerspace with Jacqui Kao

The next session I went to showed us about some makerspace tools that you could use. The company that makes them is called Fischertechnik. They have reusable parts, which can be really useful in a classroom or for companies that don't want to spend money on something that might fail and be very expensive.

During the presentation, there was an interesting discussion on buying kits vs. buying parts to make things with. Both have things that can make using them prohibitive. Kits can be quite expensive, BUT buying parts can be a very daunting task for someone who is just learning how to use these things in a classroom. It was a good discussion, but I think the answer is a lot more grey than it is black or white.

An interesting website was shared during this presentation, that I hope to look at later: Thingiverse. The site contains a lot of pre-designed things (for lack of a better word) that can be printed out using a 3D printer.


Maker Spaces with Chris Clay & Mark Mack

The last session I went to was a discussion about maker spaces and maker clubs.  One of the teachers from Elim shared with us a project one of his students completed: a word clock. The student came and they discussed the process and challenges they faced in making it. The one student alone put about 60 or 70 hours into the project (which was quite impressive, as shown below). One thing that did come out of this discussion was that the original club had a lot of members and they all were working on the same project. Over time, the numbers dwindled until it was just the one boy who ended up finishing it. The teacher spoke that perhaps it was too difficult of a project to START with (not that it was too hard, there is a difference). So, big ideas are great, but aim for them one small step at a time.

Then Chris Clay (of Mind Lab fame, when I was in their course) spoke about making robots out of recycled materials which could cost less than $25. He uses Arduino boards and imports most of his parts from China (like I've started doing recently). He showed us several models he had made and discussed the challenges. He is one to keep following for tips about this as he has spent the last few months, testing and prototyping lots of different things and is in the process of helping schools along their journey. He spoke of a new way to program Arduino (I haven't learned the original way yet!) which is much like Scratch.  It's called Snap.

Another thing that Chris (briefly) showed was Lilypad Arduino. I have heard of this before and was considering it. It's a small arduino board that can be sewn into clothing to make wearable technology. I've ordered some of these parts to have a play with so hopefully that will be another post on this blog in the near future.

 Overall, it was an interesting day. Most of the things we talked about I had some knowledge of, but each session helped me build on that knowledge and has pushed me even further on my journey. I've got some more confidence to try some new things.

Also, I find that spending time in the real world (as opposed to the virtual world of twitter and blogs) is quite beneficial for my thinking process. People share ideas, ask questions and challenge me. I'll definitely keep attending more of these unconferences!
