[Jprogramming] J Midterm exam 2011

[Linda Alvord]

I always knew kids could learn APL.  It is comforting to know that they can
learn  J also.

Subject: [Jprogramming] J Midterm exam 2011

Kids can learn J!

I teach a highschool class in J, attended by 14 students.  For my 
midterm this year I set 16 problems.  I posted the exam on the Web 24 
hours before it was due, with instructions that they could bring 
handwritten notes to class, where they would type in their solutions 
during the 2 hours of the exam.

The median score was 7, with all but one student offering 5 correct 
answers.  One student got 12 problems right and made a tiny error on a 
13th.  Amazingly, 2 students solved all 16.  Astonishingly, one of those 
students provided tacit solutions for 13 of his 16 correct answers 
(tacit was awarded extra credit).

The exam can be seen at

and my suggested solutions at
