The weakness of education research

Saturday, 06 September 2014 | 0 Comments

This is my new go to post when I see a new idea in education labelled as research-based, This Is Interesting & Depressing: Only .13% Of Education Research Experiments Are Replicated. That blog post also links through to the press release and full paper as well as this summary video:

... in the current education research process we seem to focussing on a lot on novelty and what's new and less on focussing on the scientific process...

Preparing to Engage, Enhance and Extend

Tuesday, 26 August 2014 | 0 Comments

I am presenting twice in September about how I use technology to engage, enhance and extend in my teaching.

I guess, this is a promo.

My focus in this presentation is on using a projector, the internet and a digital camera to improve the learning experiences in your classroom. Seems simple, but I suspect these tools are often overlooked for their true capabilities. Rather, teachers are being tantilised by BYOD, tablets and apps.

Fridge Shelf

Engage

How does this simple image of the bottom shelf in my fridge help get my students talking and learning about capacity?

[I used this image just today and one student couldn't believe I was using a photo from my own fridge, not sure why.]

Parts of Circle

Enhance

How is this better than the static images of a textbook?

Racing Car

Extend

How does a toy car extend my students?

 

 

 

 

I will be presenting these ideas and much more in two sessions (each slightly different):

 

 

Maths in ACtion!

For DEC teachers, this is a 90 minute workshop.

I'll also be presenting at the MANSW Annual Conference.

Stem-and-leaf plots… an activity

Sunday, 03 August 2014 | 0 Comments

I recently came across the blog Resourceaholic. As a fellow resourceaholic, I immediately added it to my feed reader. In the post, Long Live Stem and Leaf, there's an image of a "real-life" Japanese train timetable represented as a stem-and-leaf plot, found on Wikipedia.

So good, I've added it to MathsLinks:

Glenn said to me, 

We should do the same, would be much more compact.

Good idea. I went to the Sydney Trains' timetable for the Western Line.

Here is the resulting stem-and-leaf version for the station local to me.

The shaded orange cells are express services, the strike-through purple cells are for trains on the Cumberland line that also stop at this station.

This compares to the downloadable 25 page PDF version (obviously with much more detail, 55 clicks on the on-line version to get all these times, or a $3.79 app.

If I were still a commuter, I wouldn't mind a credit card sized version showing there and back around my common travel times.

Why?

Well, it's always nice to have real data and there are only so many times that you can plot the heights of students in the classroom. Plus, this is a practical activity that could be as small or large as suits your class.

Lots of the common data discussions could happen, outliers, clusters.


Maths Teaching Crisis

Wednesday, 09 July 2014 | 0 Comments

Everyday in the media, maths teaching and teachers are being judged. Maths teaching is in crisis. A shortage of maths teachers (and science) and the, presumably poor, quality of maths teaching.

This talk has been around since I've been teaching, and presumably longer. In fact this "crisis" may have been around since 1868:

In a report dated 1868, the Schools Inquiry Commission expressed serious alarm about the neglect of school mathematics and about the effectiveness of teaching the subject in UK.
