[Year 12 SofDev] Updated version

Fri Mar 24 16:01:16 AEDT 2017

Using an inbuilt function like isNumeric() in Visual Basic will do the same thing, and gives another place to see the KK point “processing features of a programming language, including instructions, procedures, methods, functions and control structures” ☺ .

I guess it’s entering the land of philosophical debate, but I like the line, “If you perform arithmetic on it, store it as a number. Otherwise it's a string.” There used to be an argument of data size (4 1-byte characters vs a 4-byte integer) but now we’re measuring in terabytes, that argument’s gone the way of the floppy disk.

Integers are great if the postcode is for Australia, it enforces validation right from the data type. As soon as you go international though, postcode should be a string. I think if you added in a sentence about this being Australia only you could get away with it, especially as it provides a good chance for them to do some data validation.

Thankyou Darren,

I was going to add file access but as I only have 1 week left of the term I decided to do it later, with a joint class Informatics/software I have been pushed for time. I probably should have used postcode as an integer and am hoping some of my students pick up on that and I will have to fi point 4 and in task 8 it is supposed to indicate making a tic tac toe game it was a good visual design that I found.

Thankyou very much for the feedback

I also decided to give them a choice of either 6 or 7 and either 8 or 9 as they give me variety.

Hey Vera, I just had a quick look over and thought the following … feel free to add or ignore.

  *   I’ve seen a few people mention that sorting isn’t in U3O1 specifically, but there’s no reason you can’t do it as an algorithm, so I did sorting in U3O1 anyway … to me, it makes no sense to binary search if you haven’t covered sorting first/as well.
  *   Are you doing any file access stuff? XML file formats is a key knowledge so I’d recommend putting in something that reads from/writes to a file.
  *   In task 1 you have postcode as an integer … why not a string? You’re never going to do any maths on a postcode.
  *   Task 5 refers to task 1 in the form, but your swapping question is task 2.
  *   I don’t know what you want the kids to do in task 8 … are they making tic-tac-toe? Or just a subpart of the game where the board is already 6 pieces in?

How long were you giving for this?

Darren

Thankyou Vera
