Mathematical Induction: What will the NSW HSC Markers accept for a conclusion?

One of my students asked me this question last year. Here is my research and response. 

2008 Ext 1 Mathematical Induction Question


From the marker comments (produced by the Board of Studies) they seem to suggest that there was:

• 1 mark for  step,
  


• 1 mark for 'the inductive step' (assuming true for )
  


• 1 mark for proving true for
  

In addition, from 2009, the BOS has started to provide "sample answers"


The marking guideline clearly gives one mark for proving true for n = 1 (this is actually part (i) of the question). For part (ii), one mark is given for the 'inductive step' --- i.e. assuming true for n = k and one mark for proving true for n = k+1. It looks like NO marks are allocated to the conclusion.

At MANSW's Markers Reports and advice days in the past it has been said that a conclusion as brief as "Hence proved by Mathematical Induction" would be sufficient.


However, there is no harm in taking the 5-10 seconds to write a conclusion.


In 2010, Q7(a) was a reasonable typical divisibility induction question. The marker's notes affirm one mark for proving n = 1, The inductive step and proving n = k + 1 are both important steps. The conclusion was not mentioned in the notes, except to say that there is no point writing out the structure of an induction proof (conclusion) without any attempt at a proof. The conclusion given is very similar to the previous year: "result is true for all integers n > 1 by induction."

Use an iPad (+ Griffin Stylus) & SplashtopRemote to create your own IWB instead of using a Tablet PC

I currently use a TabletPC and love its functionality. I can setup lessons in Microsoft OneNote, with links to all the resources I will be using for the lesson (including Geogebra applets). I love being able to using my table PC to write on the screen and have it automatically updated to the screen. Unfortunately I face losing my TabletPC and have been looking into other alternatives.

1. Epson BrightLink Projectors.
We have recently had these interactive projectors installed. Unlike a typical IWB, they project onto a normal whiteboard and you use a special pen to interact with the connected computer. I have found this quite freeing, being able to stand in front of the class, and point to exactly what I want. However, when it comes to digitally writing, the quality is not good enough and I retreat to my TabletPC to do any written work. The BrightLink is great for working with Geogebra!

 



2. iPad and Stylus with SplashTop Remote
I love Splashtop Remote as it allows me to control my computer from my iPhone (and and iPad, when I get my hands on one). This Griffin stylus is quite nice and it works (unlike the 50c one that I got on ebay). It is great with being interactive, but the quality of digital writing is not great - It's also difficult to get the exact point to put it on the ipad so when writing a 5, the top sometimes isn't joined to the rest of it. So, this solution is very similar to using the brightlink, with the added flexibility to walk around the room.



3. Wacom Tablet. I have seen these tablets used by Douglas Butler (TSM,Oundle) and have been very impressed with the precision he has with them. These are quite expensive, but look like the best solution for digital writing, if I do not have a TabletPC in the future.

I will write a post later about why a TabletPC is an essential tool for Mathematics Teachers.

NSW Draft Syllabus - is this really a stage based syllabus

Whilst the syllabus is presented in stages (Early Stage 1 through to stage 5), there are some peculiarities as a result of the Australian Curriculum be year based.

The Australian Curriculum clearly has Year 7 content and Year 8 Content.

 

The Draft NSW Syllabus includes the following substrands "Probability 1" and "Probability 2" and also "Single Variable Data Analysis 1" and "Single Variable Data Analysis 2"

 

Seems like it is giving a clear indication of what is "Year 7" content and what is "Year 8" content.

 

Also - it is disappointing that dot points are now linked to the Australian Curriculum Content Descriptors, rather than the outcomes - means that outcomes are less important. It is harder to teach one outcome as they are all intertwined.

 

More to come!

NSW Draft Maths Syllabus - Please give me codes like NS4.1

I didn't realise how much I liked have NS4.1 outcome codes in the syllabus documents. It made it so easy to communicate with other staff about particular content. Now, the outcomes are clustered at the start of the content and dot points do not hang off individual outcomes, but rather hang off the Australian Curriculum Content Descriptions.

Now I have to say "In Stage 4, Number and Algebra, in the Computation with Integers substrand, under the Australian Curriculum content description to Apply the associative, commutative and distributive laws to aid mental and written computation..."

Solution: Please include the AC Content Codes, i.e. ACMNA151

NSW Maths Syllabus Draft - Now Available

With 369 pages of reading... it will take a little time to digest the draft syllabus. Initial thoughts are that I'm not too keen on the new format, but stay tuned for some more thoughts on Stage 4 and 5.
