Coordimate on KickStarter

Sunday, 15 February 2015 ·

The Coordimate looks like a great idea, currently 80% funded:

Mathematical Symbols in PowerPoint for Mac

Sunday, 25 January 2015 ·

This screencast follows on from the previous Mathematical Symbols in Word for Mac.

In this screencast, I show a fast method for typing mathematical expressions involving basic symbols (like × and ÷). This method doesn't require the mouse to navigate a menu nor does it require an Equation to be inserted.

Stand-alone YouTube

Saturday, 24 January 2015 ·

Increasingly I am consuming media on my desktop computer rather than my TV when at home.

Numberphile, for example, publishes one or two videos a week that I want to watch. However, I've always found watching in the browser annoying. Two ways to improve the YouTube viewing experience are:

  1. install an extension like ImprovedTube (for Chrome) which, as the name suggests, improves the experience of watching on YouTube - stops AutoPlay for example.
  2. download YouTube videos to watch in a media player. There are online services and software that can do this. But you then have to wait for the download (rather than streaming) and I don't necessarily want a copy of the video once watched.

Being too helpful?

Saturday, 25 August 2012 ·

As I said in an earlier post...

2012 is looking like a year of quiet reflection (i.e. maybe not much on this blog), contemplation and trial and error.

Here is some recent thinking, please comment.

Frequency Distribution Table

Sunday, 25 September 2011 ·

On MathsStarters, I have added a Frequency Distribution Table tool. The tool lets you have 3 to 10 scores, you tally as you go and the frequency and total are calculated.

You could use this on a projector/IWB (the buttons for incrementing the tally are sized for an IWB). Or, students could use this to record data on their own laptop as they collect it – paperless!

Laptop Wraps

Saturday, 30 January 2010 ·

For NSW DET teachers, I’m sure you know of TaLe, and hopefully have seen some of the resources for the DER that have been published there.  One category of resources has been called Laptop Wraps (they are also available publicly).

Getting your network in order

Friday, 01 January 2010 ·

Reading blogs and networking on Twitter seem an obvious part of being a teacher.  Yet when I take in to school a shiny new resource that I’ve received through one of these means, I usually get asked “where did you find this?”.  The person behind the question is often thinking that I spend copious hours sitting at home in front of a computer “web surfing” or trying endless combinations of search terms in Google.

Making a matching activity

Thursday, 12 November 2009 ·

As I mentioned, the DER roll-out hit my classroom as we were in the midst of Algebra.  Due to a tight program and exams shortly, I had to stick with a couple of topics which don’t really allow for “play” on the laptops as much as I would have liked.

A lot of the Algebra taught at the Stage 4 level is technique, and so matching activities work particularly well to practise and review skills.

Here’s a review of some of the ways I’ve found to make matching activities for use on the laptops.

Resize to Netbook Size

Not really maths related, but handy if you’re looking at a web-site that will be used on a Netbook.

Using GeoGebra

Wednesday, 22 July 2009 ·

This article is not a “how-to” but rather some thinking about using GeoGebra (a discussion starter maybe).

Keeping organised

Wednesday, 13 February 2008 ·

I’ve found that teaching is one of those jobs where you end up making “to-do” lists.  Years ago, I was determined to do away with paper-based to-do lists chasing me around.  I started using Backpack described as an “information organiser” — Gather your ideas, to-dos, notes, photos & files online.
