A teacher in Western Australia has apparently set an assignment for her 15-year-old students wherein they had to plan a lethal terrorist attack.  Further details, as reported through the mass media, are available here  
Unsurprisingly in an environment where a major swing to conservative politics has just been recorded in last week-end's federal election, and where a major contributing factor in this was the conservatives tapping xenophobic, racist and similar sentiments buried not too far below the surface in large sectors of this country, this classroom event has generated a storm of outrage. Some reports have an explanation of the teacher's motives as trying to have students understand something of belief-driven actions of those who are demonised.  I haven't seen anything by way of a comment by the teacher herself, and it would be highly unlikely that her State government employer would allow her to make such a comment to the media anyway.
While there can be little doubt that there is valuable pedagogical material somewhere in the scenario provided by the teacher, I don't think this is a particularly sensible way to go about trying to generate understanding of the position of the Other.  It seems to me that genuinely critical educative work has to be based in a position of concern for the well-being of humanity in the first place.  Asking students to plan to kill as many people as possible in their assignment work flies directly in the face of that basic premise.  Further, critical work is surely about building ties of solidarity and understanding within and across communities of difference - I don't think this will do that is quite the ways the teacher might have hoped.  A major part of critically engaging communities through teaching must be to pick the arenas and the topics that will help build commonalities, not shatter them.
