xerou Posted April 4, 2012 Report Share Posted April 4, 2012 My IA is due tomorrow and I'm almost done. However, today my teacher mentioned that most people would be unable to score a 5 on Criterion D (results) which mentions that "the student gives a correct informal justification of a general statement". What does the rubric mean by "informal justification"? Thanks! Reply Link to post Share on other sites More sharing options...
Peanut Butter Jelly Posted April 5, 2012 Report Share Posted April 5, 2012 OP is taking math SL, which is an informal justification. However, if math SL students give a formal proof, they automatically recieve a 4/5. Informal justification just means sound reasoning with data that supports your results (which have to be correct).
