Grading

Exam 1 = 100 points
Exam 2 = 100 points
Final Exam = 150 points
#Research Reviews = 30 points
#Tree Quizzes = 15 points
#Collections Tour = 5 points

There will be two one-hour, non-cumulative, exams scheduled during the lecture hour. The final exam will be cumulative, with an emphasis on material from the final third of the course.

Research Reviews

As a research field, vertebrate biology is alive and well, with discoveries being made constantly. Each week, we will select one paper from the primary scientific literature that describes a study relevant to vertebrate biology. On Tuesdays, class will include a short in-class written exercise, in which we ask you to answer three standard questions about the paper:

  • What was the major new result?
  • How does this change what we think?
  • Why does it matter?

The written exercise will be followed by a brief discussion of the paper, during which we will call on pre-determined, but randomly selected, students to talk about the paper.


In-class assessments are worth 3 points each. 11 will be offered over the course of the semester, and the best 10 counted towards the final course grade. There will be no paper selected for the first week, or the weeks of the first and second exams.

All papers will be available electronically. A link to each paper will be posted on the course schedule below, next to the date of the in-class exercise. While many articles in scientific journals are now made available free to everyone ("open access" articles), access to other articles requires a subscription, which the UConn library buys. On campus, you should not encounter difficulty accessing the full text of selected articles. From off-campus, the easiest way to access articles that require a subscription is using the EZProxy. If you get a message saying that you may purchase access to the paper, then try again through the proxy. In some cases, it may also be necessary to quit and restart your browser. Alternative ways to access the articles via UConn's subscription are to configure the proxy within your web browser and to use the VPN. It is your responsibility to test that you have access in a timely fashion. Course instructors will not respond to requests to provide the article directly to individuals.

Tree Quizzes

On several of the research response days, we will incorporate additional questions about the phylogenetic tree of vertebrates into the written exercise. These will be worth a total of 15 points over the course of the semester. As with the research responses, you must be present to receive credit and no make-ups will be given. If you have a valid, documented reason for missing class on the day of a tree quiz, and have followed the policy on missed exams, then your quiz score will be prorated.

Collections Tours

Every student is expected to visit the EEB Biological Collections for a tour that will introduce you to the resources and opportunities in the collection. We will offer 10 different opportunities, on different days and times. You will need to sign in at the collection; at the end of the semester, everyone who has signed in will have 5 points added to their grade. Tours will take about 45 minutes; they meet at the south end of the Biology/Physics building lobby on the hour. You are responsible for finding a day and time to attend from the options below; if your class schedule prohibits you from attending any of these, you are responsible for letting us know that you will need an alternative opportunity AT LEAST TWO WEEKS PRIOR TO THE FINAL TOUR. If you have already toured the collections (e.g., in a previous class), provide us with documentation to that effect, and we will just add the points to your grade without you needing to tour the collections again.

Course Policies

Missed Exams
Any student who does not attend an exam and fails to receive permission in advance will receive a 0 for the exam. Approval of any request to miss an exam requires, but is not guaranteed by, verifiable written documentation of the reason. A student who receives approval to miss an exam will have his or her grade for the missed exam prorated based on his or her performance on the remainder of the exams. We will not give make-up exams. Every student must take the final. Permission to reschedule the final can only be obtained through procedures determined by the Office of Student Services and Advocacy.

Other Absences
No make-ups will be given for research responses or tree quizzes. The first research response from which a student is absent will be dropped. If a student misses a second one, then he or she will receive a zero. For tree quizzes, the missed exam policy applies.

Academic Integrity
Plagiarism and cheating are violations of the student conduct code, and may be punished by failure in the course or, in severe cases, dismissal from the University. For more information, see Section IV of the Student Conduct Code.

Disabilities
If you have a disability for which you may be requesting an accommodation, you should contact a course instructor and the Center for Students with Disabilities (Wilbur Cross Building, Room 201) within the first two weeks of the semester.

Classroom Conduct
We expect all students to behave in a way that is respectful of others. The Pdficon small.gif classroom conduct form, which describes our expectations in more detail, must be signed and returned to the teaching assistant by the end of the 2nd week of class.

  • Arrive on time and stay until the end. If you must come late or leave early, sit by the back door.
  • Turn cell phones OFF and store them out of sight.
  • Use laptops only for taking notes.
  • Recording is prohibited without the written permission of instructors.
  • Course materials are the intellectual property of the course instructors. Students may not make these materials (including handouts, exams and quizzes) available electronically.


Honors Conversion

Can I convert this course to honors?

Help Resources

The secret of success to this course is to not let yourself fall behind. Be sure to fill gaps in your notes and navigate blocks in your understanding as soon as possible. Should you run into trouble with the material, below we have listed some steps for obtaining assistance. While we welcome any and all questions on the material, before you contact us, please first check the resources below to see if your question has already been answered. If/when you do contact us, please understand that we will respond as quickly as we can, but we do have other obligations that might prevent this from happening as urgently as you may need (like 3:00 am the day of an exam...).

Study Materials:
The textbook for this course is Pough F. H., C. M. Janis, and J. B. Heiser. 2009. Vertebrate Life, 8th Edition. Prentice Hall. Three copies of the textbook are available at the library iDesk. Ask for call numbers XR5, XR6 and XR7. We strongly encourage you to read the assigned sections before lecture.

Study questions will be posted online after every lecture. These are intended to help you think about and synthesize information. They are not intended to provide a comprehensive study guide.
