CAS Academic Code: The CAS Academic Conduct Code is strictly followed. Academic misconduct involves not only direct cheating on tests, but some more subtle acts as well. All work handed in for credit must be your own, with the exception that you may refer to other sources if you cite the references using the guide below. It is not permissible to use another student’s work. You may discuss items with other students but your written work must be your own. If you have any questions you should consult Professor Godrick or the Teaching
fellow before the deadline. We are required to report cases of suspected academic misconduct to the Dean’s Office. Penalties for violations of the Academic conduct code may include suspension or expulsion from the University.

Discussion Sections
The objective of the session is to look at current immunological techniques.
Students will select a protocol(s) upon which to report to the group examining a paper published within the last three years which uses a selected immunological technique. Students can choose from but are not limited to the repertoire of immunological techniques listed below.
Discussion will center about (1) problems with the technique - accuracy, false negatives/positives etc, (2) alternative protocols experimenters might have considered, and (3) future work. It is estimated three students will present per session depending on size of discussion section(s).
Administration:
Each student will give instructor 1st, 2nd, and 3rd choices for topic and then be assigned for presentation throughout semester. The sessions will be organized so each meeting discusses a different protocol. Prior to talk, students will submit 1-2 page abstract of their talk for class distribution. Difficulty of protocol will be taken into consideration of presentation/abstract.
Grading:
Abstract = %
Presentation = %
Attendance/Participation = %
Discussion Section = 10% of total grade.
You are expected to be punctual. Attendance is not taken after the first five minutes.

Guidelines for BI385 Technique Talks
Please prepare your talks in the manner of a NOVA presentation i.e. for an intelligent, interested audience but an audience with NO background in the techniques you will describe or to which you will refer.
Please use bulleted high points for what you want the audience to see. Font 20 allows your audience to read your image. Copy onto transparency or prepare for power point.
Use diagrams to substitute for words whenever you can.
Remember to let me know a week ahead if you will be using power point. You will have to supply your own laptop. Plan on arriving in the room 5 mins early to make sure you can set up the laptop/projector.
General Steps in your Talk
1- Big Picture
It helps if you start with the big overview of what you will discuss. If you are
presenting two different unrelated experiments—outline up front the common
thread for your audience.
2- Procedures
What were the investigators attempting to do by using the protocol you are
describing? What question(s) were they attempting to ask?
Focus: What do we Know? How do we Know It?
Flow Chart(s) may help here.
Describe procedures
Use Diagrams/cartoons whenever you can to illustrate your talk.
What works/ what doesn’t
3- It helps the audience to understand the procedures if you give some idea of time
involved to run them. Are you discussing a process that takes a day/week/month to
run or something that is completed within minutes/hour? If both—explain.
4- Talk should end with unanswered questions—where does the researcher go from here.
