I kind of feel that everybody is overestimating high school chemistry classes. Due to regulations, costs, knowledge, etc?, many of our high school kids aren?t doing much of anything in terms of formal training for labs. They are using copper sulfate, baking soda, vinegar, a few bases, and some muriatic acid for the majority of their experiments. And, with this, they have 1 2-place electronic balance, some bunsen burners that may or may not leak at the bottom, and simple test tubes and beakers. They have 43 minutes to do lab (and that includes getting them in the room, taking roll, any instructions you may have). Add to that the fact that many of the class standards do not include laboratory skills, and one can see why lab tends to fall away more often than not.

Now of course they are not all equipped this way, but a lot of them are, and so these kids may or may not have anything before coming to a University.

We treat our incoming students (beginning classes) as if they have never had a lab before. For those who have, the beginning is a refresher - while for those who haven?t, it?s a welcome response to their nerves. By the time they are seniors we do expect some serious things from them, but leading up to that is our job, and why we are here.

That?s probably not the answer you wanted, but in my opinion it is what is happening, at least in a few states (Indiana included - but many of our students coming here have very poor lab skills).

Don?t interpret this as bad, we can turn them around. I?d put our graduating seniors against any, but for those coming in to college, we?ve had to adapt to try to include rather than exclude.

Dave (can you tell it?s summer ;)
