Biology 275: Invertebrate Zoology T, R 3:00—4:15 PM Fall 2010 Birck 235 Instructor: Dr. Phil Novack‐Gottshall E‐mail: pnovack‐gottshal[email protected] Office: Birck 332 Office hours: TBA or by appointment
Course Description Survey of major invertebrate animal groups through comparative study of their biodiversity, anatomy, physiology, development, and ecology. Focus on evolutionary relationships and importance of reproduction, development, feeding strategies, mobility, skeletonization, bilaterality, cephalization, terrestrialization, and parasitism throughout the tree of life. Required textbook 1) Brusca, R.C. and G.J. Brusca. 2003. Invertebrates. 2nd ed. Sinauer, NYC. Prerequisites: This is a 200‐level biology elective that requires you have successfully taken the introductory BIO 197 and BIO 198 courses. IDEA Objectives: 1. Gaining factual knowledge (terminology, classifications, methods, trends). 2. Learning fundamental principles, generalizations, or theories. Blackboard and technology requirement The Blackboard site will serve as a repository for additional readings, outline discussion forums, grades, and important announcements. You can get to the course site using http://www.ben.edu/blackboard. Once there, log‐in and click on the course site. If you have problems logging in or locating the site, just follow the links. A note on my office hours The best science teachers also practice scientific research. Although I do research throughout the week, I reserve Mondays for uninterrupted research. I will not regularly be available to meet with you on this day except for exceptional circumstances. You are still welcome to e‐mail me with questions and concerns during this time, and I will make every effort to respond in a timely manner. However, an e‐mail response cannot be guaranteed until the next work day. On other days, you’re welcome to call me on campus (678‐839‐4061), stop by my office or lab, or e‐mail me (pnovack‐ [email protected]). I don’t accept phone calls at my home.
Grading Policies Your grades will be assigned on a percentage scale, as follows: ≥90% = A; 80‐89% = B; 70‐79% = C; 60‐69% = D; <60% = F Exam #1 (Sept. 23) 20% Exam #2 (Oct. 21) 20% Exam #3 (Nov. 18) 20% Final Exam (Dec. 17) 20% Understanding Science Writing (Nov. 9) 10% Attendance 10% Exams (and policy on attendance on test dates) There will have three non‐cumulative exams and a cumulative final exam. Attendance is required on all test dates. Make‐ups will only be allowed for exceptional circumstances. The professor will make the determination of whether or not the documentation justifies a make‐up exam. In those rare cases where a make‐up is allowed, the exam will be scheduled for final exam week. Make‐up exams will be essay‐ based and substantially more demanding than regular exams. Do not leave campus until your scheduled final exams are over. If you have a trip requiring you to leave before your scheduled exam, you will receive a zero on the exam or have to reschedule your trip. The format of exams may include multiple choice, matching, fill‐in‐the‐blank, short answer, and essay questions. Exams will have you apply concepts learned in class instead of asking you just to repeat facts and definitions (although you will still be expected to use relevant terms correctly). Memorization, last minute studying, and over‐dependence on lecture notes are not useful strategies. Reading the textbook throughout the semester and reviewing your notes daily will help support and enrich your knowledge. The final exam is cumulative, although it will emphasize material since the second exam. Although longer than previous exams, it will have the same general format. It will occur Friday, Dec. 17 in our regular classroom 3:15‐5:15 PM. Understanding Science Writing Science is communicated in the primary literature, primarily journals. Most lay people find these articles challenging to read because they are technical presentations of original findings and ideas. To help you learn to understand science writing, you will read one recent article that presents some notable but controversial idea concerning invertebrate zoology. I will provide this article during the semester. Your assignment, worth 10% of your grade, will be to (1) read the article and (2) write a journalistic news summary explaining the discovery and its wider implications to a lay audience. Besides helping you comprehend science writing, this assignment will help you understand the role of data in scientific knowledge and how scientific arguments are structured, and 3
help you convey complex information in a succinct manner. This assignment is due Nov. 9. A late assignment will be deducted 10% per 24‐hour period (excluding weekends).
Attendance Because this class is relatively small, it is critical that you come to and participate in every class. I will record your attendance throughout the semester. You can miss up to two classes without penalty. You will be penalized 2% from your final class grade for missing each additional lecture, regardless of excuse.
Lateness See above for the lateness and absence policy on exams and the Understanding Science Writing assignment.
Withdrawing from class The last day to withdrawal from class is Sunday, November 21. If you are considering withdrawing, please come to speak with me first. I want to help you do the best you can in this class. You may be doing better than you fear!
Extra credit Extra credit will not be available in this course. Your success is your responsibility. Make the most of every assignment, knowing you have limited opportunities to counter grades you later regret.
Academic honesty policy The university faculty and student representatives have agreed to the following uniform statement of academic honesty. The search for truth and the dissemination of knowledge are the central missions of a university. Benedictine University pursues these missions in an environment guided by our Roman Catholic tradition and our Benedictine heritage. Integrity and honesty are therefore expected of all members of the university community including students, faculty members, administration and staff. Actions such as cheating, plagiarism, collusion, fabrication, forgery, falsification, destruction, multiple submission, solicitation, and misrepresentation are violations of these expectations and constitute unacceptable behavior in the university community. The penalties for such actions can range from a private verbal warning, all the way to expulsion from the university. The universityʹs Academic Honesty policy is available at http://www.ben.edu/AHP and students are expected to read it. Giving information to another student about the contents of a test or receiving such information is considered cheating, regardless of whether the action was intentional or consequential. Using cheat notes on a test is cheating. Copying from or looking at another student’s test or allowing someone to see or copy from your test is also cheating. In‐class cheating is a very serious offense. In the Biology department, the first infraction on an 4
assignment/paper/quiz will result in a zero for that task. The second infraction will result in an F in the course. Dishonesty on major assignments will result in an F for the course. All assignments in this class are considered major assignments. According to university policy, the Provost will be notified of all incidents of cheating and you will be subject to the penalties imposed by that office which may include expulsion from the university. (See Student Handbook for details on academic honesty policies.)
Cell phones, calculators, and laptops Please turn off your cell phones, ipods, Blackberries, and other electronic devices before coming to class. Calculators will be supplied if they are required during exams. Laptops and classroom computers can only be used during lecture to take notes or do assignments; you cannot use them to catch up on Facebook, e‐mail, or to surf the internet.
Policy on academic accommodations for religious obligations A student whose religious obligation conflicts with a course requirement may request an academic accommodation from the instructor. Students must make such requests in writing by the end of the first week of the class. Upon receiving such a request, the instructor will offer reasonable accommodations whenever feasible, and communicate this to the student. However, the course requirements listed in the syllabus remain in effect if accommodations cannot be offered.
Disability support If you have a documented learning, psychological, or physical disability, you may be eligible for reasonable academic accommodations or services. To request accommodations or services contact Tina Sonderby in the Student Success Center, Room Krasa 012A (630‐ 829‐6512). All students are expected to fulfill essential course requirements. The university will not waive any essential skill or requirement for a course or degree program.
What if I miss a class? It is your responsibility to come to class regularly and to take notes. If you miss a class, I assume youʹll contact at least two other classmates to learn what happened in class on the day you were absent, and to receive any materials distributed that day.
What if I come late to a class? Students who arrive to class late not only miss important information, but also disrupt other students’ learning. For this reason, I expect that you will be on time and ready to begin work.
A final caveat Your professor is not capricious, but he does reserve the right to alter this syllabus, class policies, or the class schedule to best accommodate the needs of the class. If such a change is needed, you will be given sufficient and timely notice, as well as the ability to contest or contribute to the alterations thereof. 5
