Also - thank you for the shout out to alt grading. To me, the problem is grading with points; that will always have poor results in measuring s. learning. I think contract grading for mastery is another idea. Exams built for multiple levels of demonstrated learning for the purpose of reducing blanks

When do we get to know details of the *technical issue*? Stop treating *technical issues* as some esoterica best left to wizards apprenticed to the craft. We want to know what happened so we can avoid it happening in our lives. www.theguardian.com/business/202...
