Google SketchUp

Google Sketchup is one of the applications bundled on the DER netbooks being rolled out into NSW Public High Schools in Term 3. But as it’s free, you can download it now for Windows XP/Vista & Mac OS X.

I’ve been looking for resources to help me learn this app, and you don’t have to go far from Google’s own video tutorials. But the quickest way, to get the general idea, is this screencast from the ICT Guy:

More important is to find some lesson ideas…

From 3DVinci comes a Free Teacher Guide. This is a great resource, there are three activities for maths:

  1. Patterns with circles and tesselations (my circle creation is shown to the right)
  2. Nets of solids
  3. Making some interesting objects using the golden section

There are some projects for other subjects too, but I reckon you could adapt these for maths. I’m thinking of taking the build a house project and connecting it to surface area (Sketchup can measure the area of a surface).

I’m also working out whether it’s possible to make a 1:1 drawing that could be printed out and constructed. The way I think you’re supposed to do it is with Document Setup. I currently get Year 9 to design a box to hold a mini Toblerone (roughly a triangular prism) – what I’m thinking is that they could design the box in Google Sketchup, print it out and then make it.

Have you found or got any good lesson ideas for teaching with Google Sketchup? How did you teacher Surface Area or Volume with Google Sketchup? Share your ideas in the comments.

Teach the teachers

From The Australian, Technology lesson one: teach the teachers comes this:

… “This isn’t just about teaching teachers to use the technology,” Professor Stoney said.
“It’s about teaching them to use it for learning. How do students learn with technology?

I thoroughly agree.

I’m highly IT literate. I can use a new application presented to me with a little bit of fiddling, I can edit photos, make videos, record and edit sound, build web-sites etc. But, what no-one has been able to show me is how to effectively integrate those skills I have into my teaching. I don’t want online tutorials for using software, I don’t want to be shown how the magic pen draws stars and happy faces – I want to know how this helps me teach, how this helps my students learn.

Sure, there’s lots of teachers blogging and twittering about wizz bang software and web-sites, but few seem to be recording how they apply it in their classroom. Or, they seem to have a different clientele to me.

Some of the reasons I struggle with incorporating technology into my teaching:

  • The students at my school required highly structured activities. Even student-centred learning at my school requires significant structure to allow all students to achieve something. My evidence for this is that the subject that is taught with the most structure is probably maths, and it seems to have the least behavioural issues. A structure gives the students at our school, many who come from very unstructured to wildly chaotic homes, security, belonging and an opportunity to learn.
    In terms of technology, I once took a Yr 8 class to the computer lab to undertake an activity about ratios from the Tale site. Beforehand, I had spent about 15 minutes working through it. The students were through it in just a couple of minutes – they didn’t read any of the content, they just pushed buttons till it worked – and then told each other how to get through it.
  • Combine this with low academic levels. Most students at my school struggle to apply one concept let alone multiple concepts. Whilst we try in many and varied ways to give students the ability to connect concepts and to develop their knowledge, only some students arrive at a level of higher-order thinking that allows them to manipulate, apply and present information. But, many online widgets and activities assume prior understanding of basic concepts.
  • Therefore, we need to create our own activities. Absolutely, we do… but that takes time, and with so many other demands, we can’t do everything we want to.

Another misconception worth noting in this post, is that today’s students are technologically savvy. My observation and experience disagrees with that. Much like teaching your mother to program the VCR, the students I teach seem to have a very limited repertoire when it comes to using technology: they know how to text and listen to music on their phone, they know how to search Google, and most could make an ugly WordArt heading for an assignment. Their grasp of technology only extends to what they need to know to entertain themselves and complete basic tasks. I’ve had students in a computing class that have struggled to save their work or open a program. Most students are not using their easy access to technology to independently learn; it’s the “nerds” who would have been reading books and magazines and pulling something apart in the garage when I was at school, now using the internet to learn how to take apart more complicated things.

As I thought about this I realised, that I grew up as computers were growing up. Windows didn’t exist when I started using computers, we learnt about the DOS command line, which taught us about how computers store files. We wrangled with primitive word processors to produce assignments. We learnt how to use the technology because we were interested in the technology. Now, the generation at my school, aren’t interested in the technology but it’s output – which I think means they’re not exploring the technology beyond achieving satisfactory outputs.

My point:

As a teacher, I will continue to read about and watch what others are doing with technology in the classroom, experiment with my own ideas and leave negative comments at training courses that show me how to use an application like a user guide.

As a teacher, I also want to broaden the horizons of my students about what they can achieve with technology, how they can use it to make their life better and increase their opportunities in future employment.

Finally, I want to encourage more teachers to share. Generally, I think teachers hold on to the resources they create like precious gems – sharing must be earnt or paid for, but we should really have moved beyond that. Create a blog or a wiki, share on someone else’s blog or wiki. Imagine if every Year 9 Maths teacher in NSW was asked to create one resource for use on the DER laptops – we’d have enough stuff to cover a year’s worth of classes many times over.

Laptop rollout

I recently contributed some comments to the executive at my school about the DET roll-out expected to be happening soon. A slightly editted version is below. I’m really not sure where the executive are at with this roll-out, I haven’t heard much except from the computer coordinator – it’s a shame, or more accurately, it makes me nervous, because there is the potential for a lot of problems to arise from this roll-out if we’re not prepared. I’m republishing my comments because they might help you in engaging with your school about planning and preparation.

School Policies

Like other aspects of our school activities, we must have expectations and rules in place before this roll-out commences:

Student expecations – this will cover:

  • Technical – e.g. charging
  • Responsible ownership – e.g. looking after the machine, bringing it everyday
  • Ethical – e.g. appropriate use, cyber bullying, privacy (camera in computer, ability to record audio)
  • Behavioural – e.g. respecting requests by teacher’s to put laptop away

Teacher expectations – what does student use of laptops look like in a classroom. For example:

  • Should it be a standard that class notes are still kept in a workbook. Writing notes in Word is not an effective use of technology in the classroom.
  • Teacher’s commit to professional development (formal and informal), seeking out resources, sharing resources and ideas.
  • Management ideas – what to do when:
    • Student’s forget laptops, when you have a lesson planned that uses them.
    • Laptops in class that are not charged, or run out of battery.
    • Dealing with demands of students to use laptops.
    • “Seeing” what students are doing.
    • Teacher monitoring of student activity
    • Casual teachers in a classroom full of laptops

Professional Development / Training

This needs to be more than online tutorials.

For teachers, 3 areas:

  • Introducing teachers to the machines
    Basic use of the laptops, fixing common problems.
  • Software
    Effective use of the applications.
  • Pedagogy
    Creating netbook based lessons. Moving teachers beyond Word, PowerPoint and Google.

For students:

  • Expectations and rules
  • Technical procedures
  • Introducing students to the machines

Dam Water

Still on capacity. With Australia having been in a drought since 2003 another interesting way to engage with the topic of capacity is to look at the water storage levels.

The Sydney Catchment Authority provide weekly statistics on water use and storage, including an interesting graph that’s been kept since 1998.

Available water storage at 11 June

Unfortunately, the graph is not very high quality to show on a projector. The Quarterly drinking water quality report has a higher quality version (not as recent) in a PDF.

There’s lots to discuss from this graph and other information on the site.

  • For starters, you get to consider millions of megalitres.
  • When did Australia go into drought?
  • How did the “total system full operating storage” increase in 2006? (expanded storage in April 2006)
  • You could also use the Water supply summary and look at a rain effected week and a dry week, discussing the net weekly storage change.
  • Find the average weekly supply for a year, and calculate how many weeks worth of water Sydney has available.

Related, but not necessarily available to everyone – find out if your school has a Watersave Smart Water Meter. Inline with our water supply, this device sends data to the internet every 15 minutes about our school’s water usage. Teachers and students can get access to the data through a web-site, and can change settings of the graph displayed and also download the data for further analysis in Excel.

This graph shows Monday-Friday of last week (Monday was a public holiday). Clearly our school has some water leaks.

My previous post on having an IWB in my classroom was written about three weeks after it’s installation. Tomorrow, we’ve got an IWB consultant/trainer/type-person-thingy coming to school, and I was asked to share what I’ve been doing with the IWB. So I wrote a quick list.

Transparent layer

  • Annotating worksheets

Interactive demonstrations:

PowerPoint

  • Consumer Arithmetic topic, Yr 10
  • Transformations animation
  • Ratios – simple animation
  • Equations – seesaw
  • Scientific Calculator
  • Longer notes – e.g. Congruent triangles
  • Step Graphs

Photos

Graphs

  • Dam storage
  • WaterSave
