Key Competencies

I like the New Zealand Curriculum. I get excited by things like the Vision and Values in it. I think its awesome that we are encouraged - expected, even - to explicitly teach about citizenship, to integrate creativity, and to develop curiousity.

Anyway, one of the big pushes in our school right now is to make the way that we teach the Key Competencies more explicit in our classrooms. I think this is a great idea, so long as it can be done relatively painlessly. Fortunately, this is possible. I used the activity below with my Y10 students yesterday:

Key Competencies Self Evaluation

I just wrote this on the board, and typed it up this morning so it could be shared. Some students found the matching difficult, and I worked with them to remind them/build with them a definition of what each KC actually is. Some students flew through it, and were coming to me with their statements and wanting to know what to do if they thought they did the KC twice. I haven't had a good look at what anyone wrote yet, but I will do that soon and give some feedback and feedforward. Overall, though, it was a simple activity that students got into far more than I expected. I guess all my excitement was infectious for some people.

The perils of trying new things, and why it's important to try

I can totally see why teachers, heads of departments and school managers and governors stick to what they know. It's just so much easier than setting fire to the past and starting from scratch (or even just hacking the past back to rubble and then trashing the useless bits).

So, one of the things about the new units we're using in junior science is that they need fine-tuning as we teach, and that is hard work. It's worthwhile work, but it's not like any of this stuff has been tested before, or even like any of the teachers have worked in schools where science is taught this way. So each lesson is a learning experience.

Today, I learned that some students are idiots. Well, that's a pretty mean way to describe it, so let me say it in a more professional way. Some students are so accustomed to being given knowledge that they find the most simple of self-directed tasks daunting - even paralysing. So they cover it up with not caring. This, then, is the most nerve-wracking part, for me. I am trying something new, and expecting students to try something new, and expecting my staff to try something new.

Sometimes, I wish we could all have a group hug.

One of the things I like about being a teacher...

Is trying things first.

Next term, the Y10 class is doing a unit based around investigations and different inquiry processes. It features self-direction, individual learning outcomes and all sorts of happytiems so-hot-right-now educational features.

But the bit I am happiest about is that there is an exemplar for the first round - for very low ability students, they can use the exemplar as a template and basically plod along in the exemplar's footsteps.

Naturally, I get to make the exemplar.

Even that wouldn't ordinarily be enough to excite me, but I am making my exemplar about using plastic bags as t-shirt transfers. Yeah, I know, exciting right?

Look at this example of what someone made with plastic bag transfers:



I was inspired by three posts on Filth Wizardry - post one, post two, and post three.

And there is lots of science behind this - like why the particle structure of plastics makes them prone to melting, not catching alight. Why some plastics are softer and more melty than others. Like where plastics come from in the first place. Even though the tutorial gives basic instructions, there is still plenty of scope for investigation and coming up with a solid hypothesis. My exemplar deals with the effects of plastic type, holding the temperature and time of fuse constant. At the moment, though, I am freeform experimenting, to get the basic range of my constants settled. I will have pictures later.

So, I'm hoping that a few other students will choose other plastic recycling topics to use for their first investigation. I have some awesome tutorials on fusing plastic bags - here, with patterns if you want to make a rain hat or bag and here, with some more crafty ideas, and even a video tutorial:



But I need more! I'm going to exercise my google-fu later and come up with as many awesome plastic recycling ideas as I can. If any readers have ideas, I'd be delighted to hear them too!

But getting back to this unit of learning. Not many students are going to grasp quite what I'm on about quickly and be able to run with it. Some will, and I am really looking forward to seeing what they and their awesome imaginations come up with. But many will need a lot of support to get through it. That's where the exemplar and some supported options come in - at least for the first round of investigations. And if I get to play round with making t-shirt transfers out of the fifty million plastic bags littering my house, that's even better.

Good teaching, good learning?

So, today I did a rather adventurous activity with my Year 10 science class involving mixed ability grouping, student-directed activities and a peer-assessment survey to follow up. One of the things I did in the peer-assessment survey was ask about how well I did. Specifically, I asked how well I explained my instructions, how well I explained the content, and how well I responded to questions.

After seeing these results, I am doing a little reflection on how I actually do respond to questions. Two of the three groups gave me an unfavourable ranking for my question-response skills.

My default, whenever I am asked a process question (like, "how do I fold this paper?"), or even a content question, is to refer them to someone who is successfully doing the process or task. My view is that students should turn to each other for advice, so long as the questions are appropriately difficult for them. If no one gets it, then I am definitely at fault and should explain. Otherwise, they can work collaboratively to find answers, and this includes asking someone else for help on what a word means or what a question is asking for.

But it occurred to me that students still think that teachers are the founts of all knowledge and that an answer from me is 'better' than an answer from a classmate, even if the content if exactly the same.

Since I don't want to have to answer the same questions fifty million times, I guess I have to take some action. Here are some thoughts:

1. Work on my instructions. In particular, make better use of bullet points and short, sequential sentences in a list rather than a short, paragraph-style set of instructions

2. For each class, assign two or three people (in a rotating roster) who will be experts on explaining tasks. Then the role can be filled by people who have a good track record on understanding the type of task we're doing that day

3. Do more examples and modelling and make more use of templates

I shall continue thinking on this and making improvements.

Ooooh, practical thinkies

One of the things science students always say, no matter who their teacher is, what year level they're at, whatever, is that they want more practical work.

This is awesome, but also a little problematic for teachers. The reason why I am conflicted over it is twofold. First, by the time I get my grubby little scientific mitts on them, students have usually defined what practical work is in their heads and it is a pretty narrow definition. It almost always includes bunsen burners and WORKSHEETS where you fill in things (like the aim and the method) and there is always a defined end point which you know about going in (because, usually, you've covered the topic in class already and so everyone knows that the candle gets lighter as you burn it). Second, they are often woefully useless at self-preservation and so teachers spend an awful lot of time making sure that the classroom is not set alight and that no one tries to drink the acid.

But we have to perservere with this. Experimentation and investigation are essential (the justification for that is a topic for another day). So, right now, I am devising a block of work around chemistry and skin care that will involve enough practical work to satisfy the most demanding adolescent audience. Even better? There is no set end goal. There are activities on the way, but the final golaposts require creativity, critical thought, and actual original experimentation.

Today, I am so happy.

Playing round with content creation

I have no voice today, so I am at home messing round with animoto and Stupeflix to see which one is going to work best for introducing students to the idea that they can create their own little learning videos.

I made one in each provider, both on the same topic - Air Pollution. We're studying that, briefly, as part of our unit on fuels in Y10 science.

Here is the animoto one:



I like this because:
They have music available to use as soundtracks
Their mixing is pretty funky and I love the visual aesthetic
They make embedding and sharing really, really easy

I don't like it because:
It's limited to 30 seconds only
Images have to be saved to your computer, you can't input urls
If you put in too much stuff, they cut it instead of giving you the option to cut it
Their flash uploader is incompatible with my school laptop settings and the simple uploader is hard to find

Here is the stupeflix one - youll have to follow the link, because, as I say below, embedding is not it's strong point:

Air pollution video

I like this because:
You can download a copy to your computer
You can make the videos as long as you like
The visual is pretty clean and there is plenty of room for text
You can control how long each image set appears for

I don't like it because:
You have to use music from your hard drive for sound tracks - royalty issues, anyone?
Their flash uploader is incompatible with my school laptop and there is NO simple uploader to be found (I'll be telling them about this one directly)
There is no easy option to embed and only a few sharing options are available (I will also be giving them feedback about this)


So, as you can see, it's not easy to choose. I'll have to provide the students with a step-by-step guide anyway, and I'm not sure which would be most painful to write. I think I shall discuss this with my minions and we'll decide which one is going to give us the fewest headaches while providing the coolest learning experience for the students.

I love school *displays unseemly enthusiasm*

This morning has kicked off brilliantly - although I could do with more coffee. My Y10s did an interesting reading exercise about fossils, my Y13s estimated the rotational inertia of each other and used it to explain why we put our arms out when we balance, and my Y12s demonstrated Newton's First Law with an egg. Have some video evidence:


I'll stick this video on the school site too, so the students can access it. They had a lot of fun making it, even though there was a lot of "no, YOU do the voiceover" going on. We didn't have time to add a proper audio track, sadly. Nevermind, it's pretty good for their first ever attempt at using Movie Maker and Audacity on the same day.

Java problem solved, wordle made of awesome

So, this is the wordle I made for a vocabulary exercise for a reading on convergent boundaries:

Wordle: Convergent boundaries of tectonic plates

The idea is that they get the wordle and a list of vocabulary questions - not content, not yet - to answer. The questions are ordered from easy to hard, so that more able students can start with a harder question. After answering the questions, the students then go on to using the actual reading to answer content questions.

I'm pretty stoked with this, and think it will work well as a way of supporting vocabulary learning without being a boring list of definitions. I can circulate throughout the class and give support to students who are struggling without the rest of the class being bored.

In case anyone is interested, here are the questions (with the answers in brackets):

  1. What are the four biggest words? (plate, earthquakes, mountains, collisions)
  2. Put one word into the gap to complete the sentence using these words: Plate collisions _________ earthquakes and mountains (cause or make)
  3. Find the word in the wordle that means:
    the part of the plate that collides with another plate (edge or boundary)
    the place where the land meets the sea (coast)
    a really big number (millions)
  4. Make three sentence using words from the wordle (plus a, an, and, the, are and other joining words) (eg. When an oceanic plate meets a continental plate to make a convergent boundary, you get a trench in the ocean and a mountain range)
  5. Plates come in two types – continental and oceanic. What do these words mean? (about continents and about oceans)
  6. Adjectives are describing words, like tiny. Find four adjectives in the wordle. Write a sentence using each one (eg Plate collisions take place over a really huge time)

Next time, I want the students to make their own wordles. I just have to find a way for this to happen *makes a considering face*

YouTube is my happy place

Nearly every day, I am grateful for youtube. Today, it was the turn of my Y10s to benefit from the fact that people worldwide have waaay too much time on their hands.

We're studying electricity, and my class is up to generating electricity. We did a little thing yesterday on turbines and the main types of generation. Today I wanted to ease them into a reading activity on wind power, so we watched a video on youtube. I backed it up with a little worksheet, of course.

The video was a parody of NIMBYs and their complaints about wind farms. I thought it was hilarious. The students just thought it was odd. The worksheet asked students to tick the reasons against windpower that actually appeared in the video, and cross those that did not appear or had nothing to do with the video. Then there were a couple of more probing questions for the more advanced students - I see this class right after lunch on Wednesdays, so I didn't want anything too complicated.

It worked really well, was quick, simple, and made the students laugh (although they claimed that he wasn't funny, just annoying). What's not to love? If you need to have a laugh, just watch it and giggle
