What We Have Been Up To In Class

In Biology we have been studying arthropods. The creepy-crawlies are a favorite with the students. Never underestimate the "gross factor" in keeping their attention! We had our first dissection, the crayfish. It went very well and the students were all excited and really caught up in the learning. At the end of the dissection I gave them their first lab practicum. This is where they move from station to station answering questions while looking at marked areas of the crayfish. College science professors love to give this type of test and many students who have not been exposed to practica will bomb the first test. You have to prepare differently for a test of this type. You can't simply memorize material from a book like they are used to doing. That's why I always break my students in gently to experiencing lab tests. With the crayfish I make it pretty basic. Even then some of them do not perform well. It takes some students a practicum to figure out how to correctly prepare for them. You can tell them over and over that they study for this type of test primarily by carefully completing the lab and then drilling with their lab partner over the material and some of them just don't get it. Experience is the best teacher and those who do not perform as well as they wanted to on the first practicum will quickly catch on and make a much higher score on their next dissection. For us this will be the perch since we are moving into the chapter on fish. It is always exciting watching their progress.
We are coming up on about 5 weeks remaining in the term. Boy, time flies when you are trying to cover so much material. Ultimately you have to pick and choose what material to study and what to leave out because of the vast amount of information in the book. I try to include everything that will help those who are going on to take more advanced biological courses to succeed and to give those who are not science oriented a new appreciation of the world around them and the ability to think critically. This will aid them even if they are not meant to be future scientists or doctors. One of my goals is to enable them to help make their own decisions for medical treatment rather than just relying on the knowledge of their doctor.
