BIOL 335 (Invertebrate Zoology) Review, Stan Eisen, 2008

Objectives and Grading Criteria:

For the lecture:

Objectives:

• To introduce students to the diversity of animals without backbones and understand the evolutionary relationships and taxonomic classification of animals as currently understood.

• Learn to identify animals (to phyla, class and sometimes lower taxonomic levels) by sight.

• Become familiar with the collecting, taxonomic identification, and curatorial methods for preserving invertebrates.

• Improve dissection techniques and learn functional anatomy of select invertebrates.

To meet these objectives, you will be looking at specimens during the same lecture hour that they are discussed. As a result, the lab time will be freed up to conduct collecting trips and long-term projects. There is one extended field trip tentatively scheduled for the weekend of September 28-30 to the Gulf Coast Research Laboratory near Biloxi, MS.

You will be graded on the following:

1. Four semester exams, each of which will count 1/7 towards your final grade. All exams will be comprehensive and will include short-answer, multiple-choice and essay questions;
2. Weekly, non-comprehensive quizzes, given on the Friday of each week. These quizzes will cover the previous week's lectures only, and will consist of short-answer and multiple-choice questions. Collectively, these quizzes will count 1/7 of your final grade.
3. A comprehensive final exam scheduled during Final Exam Week. The final exam will consist solely of short-answer and multiple-choice questions. These questions will be drawn from previous exams, and will count 2/7 towards your final grade.

For the lab:

Objectives:

1) To learn collection techniques routinely used in population and taxonomic studies;

2) To acquire experience in utilizing taxonomic keys;

3) To conduct field and laboratory studies.

Each of the following will count 20% towards your final grade:

1. One laboratory report. This laboratory report will deal with the biota and chemical characteristics of the Gulf of Mexico near the Gulf Coast Research Lab, located in Ocean Spring, MS. (Here are views of CBU’s visit to GCRL in 2002.) We will be visiting the GCRL during the weekend of September 28 -30. During that time, we will collect benthic (ocean floor) and water samples to examine the biota of the Gulf, and we will collect water samples to determine chemical characteristics. Again, we will have access to a laboratory report filed by a previous Invertebrate Zoology class;
2. Weekly non-comprehensive lab quizzes. The clock in the hallway will serve as the standard for the class for which people should synchronize their watches;
3. 1 comprehensive mid-term exam;
4. 1 comprehensive final exam.
5. An invertebrate collection. Details of this collection are described in the lab book.

Please note that most of the experiments you will be conducting require cooperation and sharing of data. Although you are welcome, even encouraged, to discuss the results and meaning of all experiments, each of you is responsible for submitting a separate lab report.

Classroom Management Details

I assume that you have the intention of learning something when you attend class. Therefore, I would appreciate it if you would do the following:

1. Arrive on time. During quiz and exam dates, I shall close the door to prevent late-comers from disrupting the administration of the quiz/exam;
2. Mute or turn off your cell phone prior to the beginning of class. If you don’t, then I reserve the right to answer your phone. (I promise I’ll be civil.);
3. Restrict your use of laptop computers to note-taking, or if requested, to access appropriate web sites to acquire information that is directly pertinent to the class. If you’re more interested in using the computer for inappropriate uses, such as instant-messaging your friends on Facebook during class time, then you don’t have to suck up valuable oxygen that the rest of us can use in the classroom.

GUIDELINES FOR LABORATORY REPORTS

1. Please DOUBLE-SPACE your laboratory report, and use margin size to 1 inch.
2. Place a cover sheet at the front of your laboratory report. The cover sheet should have your name, the report title, the course and section numbers centered on the page. PLEASE DO NOT PLACE YOUR LABORATORY REPORT IN A PLASTIC OR OTHER BINDER.

The laboratory report should include the following sections:

1. An ABSTRACT section, in which you describe in briefest form, the purpose, primary results and conclusions of the research report. By convention, it is 200 words or 3% of the laboratory report, whichever is LESS;
2. An INTRODUCTION section, in which you provide information pertaining to the problem as it is recognized and in which you discuss background information which would be pertinent to the reader. The purpose, in which you specify the questions to be addressed in THIS lab report, should be in the LAST paragraph of the introduction section;
3. A MATERIALS AND METHODS section, in which you discuss the organism(s) under study and the experimental protocol in "text" form. PLEASE DO NOT INCLUDE A MATERIALS LIST. If there are several parts to the experiment, each part should be described separately. Briefly describe, in text format, the protocol you followed in conducting the experiment. If there are several parts to the experiment, each part should be described separately;
4. A RESULTS section, in which you discuss the data from each part of the study in the same sequence as the parts were described in the Materials and Methods section. Use a paragraph to tell the reader what the main point is, and at the end of the sentence, refer to a specific Table or Figure, as in the following: "Seedlings exposed to either .1% or .2% phosphate grew vigorously, but the controls did not (Figure 1)." It is essential to convert or present the data in an understandable format. CHARTS OF RAW DATA ARE NEITHER NECESSARY NOR DESIRABLE!;
5. A DISCUSSION section, in which you relate the results of your experiment to the general body of knowledge pertinent to this area of research;
6. A REFERENCES section, in which you list the references used for background information and/or protocol procedures, including your laboratory textbook.

CRITERIA FOR THE GRADING OF PAPERS AND EXPERIMENTAL REPORTS

The report grade is a composite of three grades based on spelling grammar, and content.

I. Spelling counts 10% of the total grade. Each different spelling or typographical error will usually result in a point deducted from the maximum. However, if one word is consistently misspelled, it will be deducted only once. Low grades in spelling can be avoided by keeping a dictionary on hand and proofreading your work before you submit it for review.

II. Grammar counts 20% of the total grade. Each grammar error (wrong tense, poor sentence of paragraph structure) will usually result in a point deducted from the maximum. Low grades in grammar can be avoided by proofreading your work before you submit it and by writing practice essays.

III. Format counts 30% of the total grade. The format for your laboratory reports should follow that of a typical research article, with the following sections mentioned above

IV. Content counts 40% of the total grade. The kinds of questions that are considered in evaluating content include the following:

1. Is your information accurate?
2. Is your discussion logical?
3. Did you transform the raw data into a more useful and appropriate format?
4. Do you adequately support your argument?
5. Do you adequately correlate and contrast your data to previous experience?
6. Do you support your conclusions with the appropriate statistical test(s)?

You should write your reports as if you were submitting them to the Transactions of the Tennessee Academy of Sciences. I, in turn, will review them as if I were an editor for the journal.
