Tests and Quizzes


Pop Quizzes

Pop quizzes may be given at the beginning of a lab period to encourage students to read the lab protocols and Web pages ahead of time and come to class prepared to do the lab. They will typically consist of five, short-answer questions that are worth two points each, and are based on the contents of the lab protocol and Web page for that day’s lab. These might include questions such as
What is the name of the piece of equipment we will be using?
or
Define xxx,
where xxx is some important term with which students must be familiar. Since the reason for these pop quizzes is to see if students are arriving on time and are prepared for class, if a pop quiz is missed, including the situation in which a student arrives 15 min. late for class when everyone else has just turned in their finished quizzes, it cannot be made up.


Field-Hike Quizzes

Field-hike quizzes will be on the days noted in the schedule for the semester. They will consist of going out on a “regular” hike and noting any new organisms we see, and also answering questions about any organisms we see that should be familiar from previous hikes. These quizzes are fill-in-the-blank, and typically include 25 questions at two point each, for a total of 50 points. The questions asked about a particular organism will depend on what has previously been discussed about that organism, and might include such things as
What is it?
and/or
In what plant family is it?
or
For what is it used?
or
How are its leaves arranged?
Anything we saw (or heard) on a previous hike during the current semester and that we happen to see again is “fair game.” Because these quizzes will be based on whatever we happen to see when we’re there, it is pretty-much impossible to administer a one-on-one, make-up, quiz hike, so the policy is that if missed, these cannot be made up.

If it is raining, the instructor may choose to do one of three possible things, instead: a) shift labs around and re-schedule the field-hike quiz, b) collect plant material and bring it indoors for a “show-n-tell” quiz, or c) project photos of some of the organisms we’ve seen and ask questions about those photos.


Other “Regular” Quizzes

In winter, when it’s too cold to go outside and all the plants are under snow and not visible, the regularly-scheduled quizzes will cover the indoor labs, instead. In that case, a particular quiz will cover the labs that have been done since the last big midterm (or if it is the first quiz, since the beginning of the semester). These will consist of 25 questions that are worth two points each, for a total of 50 points. These questions will be fill-in-the-blank, and will include not only concepts from the protocols and Web pages, but also questions based on what was done in those labs and the results that were obtained (Do you understand what was done and why, and what did you learn from doing that lab?).


Midterms and Finals

These will be worth 200 points each, and will cover material from the labs that have been done since the last such “big” test. Each will be divided into two sections: there will be a 100-point closed-notebook section and a 100-point open-notebook section. The first test that is missed may be made up before the next lab period, but if there are any hands-on and/or demo questions that cannot saved from the original test date and re-set-up at a later date, students who make up the test late will forfeit the points on those questions. Only one, late, make-up test is allowed, and all subsequently-missed tests will be given a score of zero (0) points.

The closed-notebook section will include about 20 Greek and Latin wordstems (found in the protocols and Web pages, and/or given verbally) to be translated into English — for example,
Tell what ‘bios’ is in English.”,
about ten definitions of key terminology — for example,
Define ‘accuracy’.”,
and a variety of short-answer essay-type questions that could range from something such as
Draw a 250-mL beaker with all lines correctly indicated.
to
Use a pH meter to determine the pH of this solution.
to
Calculate the average of the numbers 1.00, 1.02, and 1.05.
to
Explain why water forms a meniscus in a glass container.

On the subsequent, open-notebook portion, students will be allowed to use lab protocols which are permanently bound into their protocol book and items which are a permanent part (written in or mounted with contact paper) of their lab notebook, but not a bunch of loose papers that, “...but I didn’t get time to put them in, yet.” This portion of the test will include a section of questions to test the completeness and correctness of the information in your cumulative lists — for example,
What is the common name for Asimina triloba?”,
where you would not be expected to memorize that information, but would be expected to find it in your lab notebook. There may be some fill-in-the-blank questions covering such things as
Identify this piece of equiment used in xxx lab.”,
or
Name this microscope part. ”,
etc. There will be more short-answer essay-type questions, which could range from questions such as
If 100 mL of dH2O was found to weigh 33.62 g and 100 mL of JunkPop was found to weigh 34.63 g, how many teaspoons of sugar are in one can of that soft drink?
to
Explain how and why the energy ‘budgets’ of Ragweed and Goldenrod are different.
to
Draw and label the face of a sphygmomanometer.
to
Make a buccal smear and get a representative group of cells in focus at 400×.


End-of-Class Pop Quizzes

While, in general, these will not be a regular part of lab, it is possible/probable, on a day when microscopes have been used, that the “microscope police” will come around after everyone has left to grade students on how their microscopes were put away. Additionally, if it is noticed that numerous students have developed the habit of rushing through labs, not doing a thorough job, and not really spending the time needed to really focus on the job at hand, and/or if many students decide to skip a particular hike just because they “don’t feel like it,” then it is entirely possible that a surprise, end-of-class, pop quiz might be given to those students who are still present in class. If that happens, that quiz would typically be very short and would be the sort of question(s) that should be very easy for anyone who has been paying attention to answer. Since the purpose of these quizzes is to encourage students to stay for the whole class period and be engaged in that day’s lab activity, if missed, they cannot be made up.
