									                                  BIOLOGY 102 LECTURE
                                        Winter Quarter, 2006

Professor:            Dr. Ronald DeBry, 835 Rieveschl Hall,, 556-9743

Office Hours: MW 2-3; T 11-12. I am always willing to arrange an appointment at other times.

Text:                 Life: The Science of Biology. 2004 (7th ed.). Purves, Sadava, Orians, and
                       Note: In-class quizzes will be given, using personal response system
                       (PRS) transponders. If you do not already have a PRS transponder, you
                       will need to purchase one from the Bookstore.

Prerequisites:        Successful completion of Biol 101. Biol 112 is a co-requisite lab course.

Course objectives:
This course is part of a yearlong sequence for biology majors. The sequence aims to give
students an overview of biology before they take specialized elective courses. Other programs in
the College of Allied Health Sciences, and tracks such as pre-med, pre-vet, and pre-pharmacy,
also require or recommend this course. If you are unsure about whether or not you are
required to take the majors version of biology, check with your advisor. Many non-biology
majors can take the 104, 105, 106 sequence. Biol 101 focuses on metabolism, cells, and plants;
Biol 102 focuses on genetics and evolution; while Biol 103 focuses on animal physiology and
development. In addition to learning factual information that will prepare you for future biology
courses, my goal is to have all students able to answer the following type of conceptual questions
by the end of the quarter:
        1. How does meiosis produce genetic variation among daughter cells?
        2. How are simple genetic traits passed from one generation to the next in sexually
            reproducing species?
        3. How are Mendel’s laws a reflection of the physical basis of heredity?
        4. How is the information encoded by genes turned into the gene products used to build an
        5. How do alleles behave in populations, with and without the influence of natural selection?
        6. How have species diverged and diversified over evolutionary time?

This course fulfills the General Education Breadth of Knowledge (BoK) area of Natural
Sciences. It promotes the development of the following Baccalaureate Competencies: Critical
Thinking and Knowledge Integration.

Class attendance policy:
Attendance will not be taken. You cannot, of course, receive credit for the in-class PRS quizzes
unless you attend class. Most importantly, there is a strong and undeniable correlation between
lecture attendance and final grade.

Electronic communication:
My email address is; put “102” in the subject line for quickest response.
Course materials will also be posted at I will communicate important
information outside of class by posting announcements on Blackboard and by sending you email
messages. You are responsible for making sure that your correct email address is registered with

Additional resources:
Your textbook (if purchased new) provides you with a Student CD, and free access to a student
website ( The website contains online quizzes, animated tutorials, and
other activities designed to help you to learn the material. You will find the website to be very
helpful in preparing for exams.

Courtesy in the auditorium:
Rules of common courtesy must be followed during lectures. This includes arriving on time, not
carrying on conversations in the classroom, not eating lunch during class, and turning off your
cell phones and pagers. If the noise level in the auditorium becomes excessive, the lecture will
simply stop. But the material listed in the syllabus will still be covered on the exams. If you are
hard-of-hearing you are encouraged to sit toward the front of the classroom. Actually, everyone
is encouraged to sit toward the front of the classroom. The screen is more visible there, you can
hear the lectures better there, you can better interact with the professor there, and there are fewer
distractions there.

Basis for grades:
There will be four lecture exams and one final exam. You will be given 25 minutes to complete
each lecture exam. With the exception of the 4th lecture exam, a lecture will be presented in the
remaining class time on exam days. It is vitally important that you be on time on exam days,
as the exam will end at the same time for everyone. Each lecture exam will cover material
since the last exam and up to the date of the current exam. The final exam will be cumulative.
The material tested on the exams will include information covered in class lectures and those
parts of the text that cover the same topics. The exams are multiple-choice and will be computer
graded. You will need to bring a #2 pencil. Bring a student ID to all exams and show it to the
person collecting the exams. Cell phones are not permitted during exams.

The lecture exam portion of your final grade will be based on your best three lecture exam scores
– your lowest lecture exam score will be dropped. There are no makeup exams.

In-class quizzes will use the PRS transponders. You will receive 2 points for every correct
response and 1 point for every incorrect response. Practice in-class quizzes will be given during
the first two days of class. Graded in-class quizzes will begin on January 6.

Registering your PRS clicker. To receive credit for the in-class quizzes, you must properly
register your clicker. You must register your clicker for Biology 102, even if you have already
registered it for another course. In Blackboard, go to the Student Tools tab and then click on
“PRS Registration”. Follow the instructions on that web page. PRS ID numbers will be posted as
an Announcement on Blackboard.

There will be online quizzes (on BlackBoard). You will receive full credit for each online quiz
simply for completing it (in other words, the points are an incentive to get you to use the online
quizzes as a study aid). You will be able to re-take each online quiz as often as you like.

Your overall grade will be determined by the following weighting: lecture exams (50%), final
exam (35%), in-class PRS quizzes (10%), online assignments (5%).

Scale for Letter Grades:
A = 90-100%          B+ = 87-89.9%                   B = 80-86.9%           C+ = 77-79.9%
C = 70-76.9%         D+ = 67-69.9%                   D = 60-66.9%           F = <60%

Grade totals are not “rounded up”. If you want to be assured of receiving, for example, a B, then
you need at least 80.0% of the total available points. Do not expect a curve. The median grade
for this course is typically a C. Once the final grades are assigned, there will be no adjustments
(except in the case of a clerical error). There is no extra credit. I will not respond to any
requests for or questions about extra credit.

Guidelines for non-letter grades:
W or EW: The last day to withdraw from class is Wednesday, March 1st.

UW: Assigned when a student ceases to attend class or never attended class, but does not obtain
a W.

I: Assigned only when a student is unable take the final exam (with a valid excuse) and the
student has a passing grade going into the final. An Incomplete will only be assigned if there is a
plan, approved in writing by both the student and instructor, for making up the final exam as
soon as practical. This plan must be approved before the regularly scheduled final exam or (in
the case of a last minute illness or emergency) as soon as possible.

Academic Integrity Policy:
The University Rules, including the Student Code of Conduct, and other documented policies of
the department, college, and university related to academic integrity will be enforced. Any
violation of these regulations, including acts of plagiarism or cheating, will be dealt with on an
individual basis according to the severity of the misconduct.

Special Needs Policy:
If you have any special needs related to your participation in this course, including identified
visual impairment, hearing impairment, physical impairment, communication disorder, and/or
specific learning disability that may influence your performance in this course, you should meet
with me to arrange for reasonable provisions to ensure an equitable opportunity to meet all the
requirements of this course. Some accommodations may require prior approval by Disability

All portions of the syllabus are subject to change. Students are responsible for any changes
announced in class and on Blackboard.
