I am stressed on behalf of one of my students, who took the International Baccalaureate diploma chemistry exam today.
Something went *very* wrong, and they were told they weren't allowed the data booklet or even a periodic table for Paper 1. I've NEVER heard of a public examination where you weren't allowed a periodic table for chemistry. Even my university exams, we got a periodic table!
The IB Paper 1 is an absolutely terrifying exam at the best of times. It's an hour long, multiple choice - but it is the HARDEST multiple choice exam ever. It takes me an hour to do one of the papers, and I'm a graduate chemist who's been teaching chemistry for 3 years. If it's true that they're not allowed a periodic table for Paper 1, I need to know, so I prepare my kids appropriately.
Let's say you get a multiple choice question about the electronic configuration of silicon. Armed with my l33t chemical knowledge, I know that silicon is in group 4, period 3, and can work out within seconds that it thus has the electron configuration 2,8,4, and can attempt to add 2+8+4 to work out the atomic number must be 14. But it takes me maybe 3-5 seconds to do that without a periodic table, compared to instantaneous lookup with. ( Read more... )
