[Year 12 SofDev] NEW TO SD

Fri Feb 10 16:11:17 AEDT 2017

Hey Fatima, the SAC for U3O1 is now a collection of modules that can be done as a folio or set of tasks. The conventional wisdom is to break it into a few pieces and assess each as a smaller task that grows in complexity/skill. So last year I gave the kids a task to read from/write to an XML file for part A (20 marks, one 90 minute double), then the next week I gave them a fully working part A and got them to write a sort/filter and enhancements as part B (20 marks, one double). The week after that, I got them to do the entire process on a different problem (60 marks, full week).

My practice SAC/class example is a car yard problem, which did the rounds last year and is attached again. I use VB for my language and the assessable dot points/rough rubric for part A I used are:

Performance descriptor

Guiding questions (note: these are a guide and do not necessarily match one-to-one with the allocated marks)

Interpretation of software designs:

Does the program have the functionality listed in the task:
Open a file and load data into a structure
Display data on the screen
Navigate through data
Edit and add new data
Save data to a file

Identification and use of data types and structures

Is there an appropriate class?
Have the data structure (array) commands been used appropriately?
Are all variables appropriate?
Are screen controls appropriate to the data being kept?

Use of processing features of the programming language

Are there examples of:
Sequence, repetition and selection?
Reading from and writing to files?
Subprocedures and functions?
Appropriate object procedures such as With?

Test data and testing table

Has the testing table been filled in?
Has every element of the program been tested with appropriate data?
Have appropriate amendments or modifications been documented in the testing table?

Internal documentation

Is there an appropriate documentation header containing name and date?
Does each module have appropriate commenting?
Is each line of code that requires explanation commented?
Are the comments included clear and easy to follow?

So there's:
* no writing a data dictionary or pseudocode - you provide it, it's assessed in the SAT
* no user documentation - that's out of the study design completely, only internal doc
* XML as the standard file structure - don't waste time with CSVs or other files
* pretty much the only things handed in are the program with internal doc and the testing table. No 4-page written report.

I'm sure others interpret it in slightly different ways but that was I thought the SAC was about.

Subject: [Year 12 SofDev] NEW TO SD

Greetings SD teachers,
I haven't taught SD in 6 years and a lot has changed.  During my year 12 SD days, the edulist helped me heaps. Now I'm back, in a new school and teaching SD again.

I am currently organising my U3O1 practice SAC  would be very grateful If someone could   share their U3O1 practice sac with me. I want to know if I'm heading in the right direction.

muchly thanx

Carpe Diem :)
