<div dir="ltr">Hi Anthony. I wish my old school had enough room for a golf course - we might manage a minigolf game near the canteen :-)<div><br></div><div>It might be hard to explain level 1 DFD processes in words. e.g. "Just include the big tasks. If a task is just a pretty trivial step towards achieving a bigger task, then just show the bigger task." If I said that, some kids would end up with a single process in the DFD labelled "Bigger task".<div>
<br></div><div>I'd use lots of examples to get the idea across.</div><div style><br></div><div style>And make a "don't do this" DFD with trivial subtasks and ask the kids to fix it. For a discussion they could argue why a process would be moved into a parent process, or why it should remain as a level 1 process.</div>
<div style>Come to think of it, I might do one of those myself as an exercise.</div><div class="gmail_extra"><br><br><div class="gmail_quote">On 3 March 2013 17:23, Anthony Sullivan <span dir="ltr"><<a href="mailto:asullivan@tps.vic.edu.au" target="_blank">asullivan@tps.vic.edu.au</a>></span> wrote:<br>
