The inbuilt functions of Apples iWork 08 Numbers are great for student marking and reporting.
I can easily create averages, rankings and then 3D graphs or tables that correlate to my data.
A personal favourite of mine is the ability to graph a student’s results next to the class average in an easy to see format. This is a great tool for informing parents of their child’s progress at parent teacher nights.
The blue line is the class average while the green line is the student’s results. And you will notice their rank is given for each individual task as well!
