You have to really know chemistry to pass their exams. For your summer question, you might eliminate the silly answers and offer:<br /><br />A. Earth moves closer to sun.<br />B. Tilt of earths axis.<br />C. All of the above.<br />D. None of the above.<br /><br />It works better when there are 3 plausible answers. The test taker must really know the subject in order to avoid the ambiguity.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-80998327840903595322016-09-24T17:49:01.327+01:002016-09-24T17:49:01.327+01:00Best kept apart, tested separately.Best kept apart, tested separately.Anonymoushttps://www.blogger.com/profile/09320614837348759094noreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-53916967476288153132016-09-24T17:19:58.704+01:002016-09-24T17:19:58.704+01:00Not necessarily a problem.

For once, I think that employers might talk to educationalists and explain what sorts of maths skills they need.

When school maths was made "more modern" much of the change was, alas, just silliness: set theory, but with no purpose, that sort of thing.deariemenoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-57707246840913771412016-09-24T08:57:26.779+01:002016-09-24T08:57:26.779+01:00Fascinating.

The second is teaching what. Finland does well on PISA but the Finns are clever enough to "teach to the test" and may be distorting their efforts so as to get good results. My own education stressed fractions and elementary algebra, but I cannot say it has influenced my life. If I had been taught statistics, life might have been different.
