Anyone teaching this course? What did you think of the papers?
I've taught this course. It's pretty thorough. There are definitely some good points, but the treatment of ADTs is insanely complex, IMO. They have linked lists implemented inside arrays, and then base stacks, queues and trees off of this. The implementations given in the text book and teacher resource are nasty and my students could make little sense of them even with various tracing tools. OOP is covered in depth and well, and it's great there is no course work, IMO. All very subjective of course...
Linked lists are best taught using a language which has pointers, like C. Stacks are a nightmare to implement in arrays, I have tried it but easy in languages which support stacks, like VB.
Tracing tools are useless. Never found one which helped me in any way. I rarely use any resources supplied by an exam board. I write my own to suit the students in front of me.
I get my Y13 students to create a stack class using an array, with push and pop methods and suitable error catching. Then a queue. Using C# now, although I did it with VB for several years. It wasn't a nightmare at all.
I did attempt linked lists a few years ago and only my very best students got anywhere. It is no longer in the AQA theory spec (although they are mentioned in the project, and that annoys me for several reasons).
