Description

This course is part of the introductory sequence for biology majors.  We will study the evolutionary mechanisms that explain how life diversified from one original “species” to the myriad of species on Earth today.  We will survey the major groups of organisms on the planet.  It will be a good time.

 

Required Texts

Purves, W., D. Sadava, G. Orians and H. C. Heller.  2004.  Life (7th ed).  Sinauer, Sunderland, MA.   (The 6th Edition is also acceptable.)

 

Van De Graaff, K and J. Crawley.  2005.  A photographic atlas for the biology laboratory.  Morton, Englewood, CO.

 

You also will need a dissecting kit.

 

You probably already have the word root book and a guide to writing (Pechenik 2004 or an earlier version) from Biol 1101.  If so, no need to replace them.  If not, then you should consider Knisely (2005), which we are using to replace Pechenik (2004).

Lab attendance

You cannot make-up labs without an excused absence.  My first choice if you miss your lab is for you to attend another section during the same week’s activity.  If you absolutely cannot attend a week’s lab activity, alternate assignments will be arranged.

 

Grades

Participation (including mic assignments)                                           120 pts

 

Exams 1-3 (100 pts each)                                                                    300 pts

Final Exam                                                                                          200 pts

 

Short Papers (3 x 60 pts)                                                                     180

 

Lab Quiz 1-4 (50 pts each)                                                                  200 pts

---------------------------------------------------------------------------------------

Total                                                              1000 pts

 

At worst: A = 90-100%; B = 80-90%; C = 70-80%; D = 60-70%; F < 60%.

I may curve up, but I will not curve down.

 

Grade expectations

Satisfactory work demonstrating a simple, but largely complete, grasp of the course material will receive a “C.”  An “A” or a “B” requires you to demonstrate more thought and sensitivity to nuance.

 

Partial credit on problems and calculations will only be given if you show your work.  If I explicitly ask you to show your work on a homework or exam problem, then a mere answer is not enough (even a correct answer)—you must show me how you reached your answer.

 

On average, this course should require 12 hours a week of work (4 credits* 3 hours a week per credit).  That means that you should expect to work an average of 8 hours a week outside of class.  If the work associated with this class appears to be either too light or excessive, please let me know.

 

Policy on incomplete grades

In accordance with University policy, incomplete grades will only be awarded under extraordinary circumstances.  Normally, I will only consider awarding an incomplete in cases where illness or family emergency prevent a student from completing the last assignments in a course (end of the semester projects, final exams, etc.).  You can only be eligible for an incomplete if your average on all graded, completed work is greater than an F.

 

Attendance policy

Lecture attendance is not mandatory, but I will take attendance and deduct 5 participation points for each unexcused absence.  Tests will be based primarily on material covered in class. Fifteen points will be deducted for each unexcused lab absence. 

 

Excused absences will be granted for family emergencies, illness, varsity athletic events, and other official university functions.  Written documentation for excused absences must be submitted and can be obtained from health services or chancellor’s office.

 

Late work policy

Unless otherwise specified, assignments will be turned in at the beginning of class on the day they are due (though they will not be counted as late if in by 5:00).  Late assignments lose 20% of their value for each day or portion of a day they are late (not counting weekends).  For example, if an assignment is due on a Friday, and you turn it in Tuesday, the assignment is 2 days late and thus only worth 60% of its original value. 

 

Policy on Academic Honesty

I have no tolerance for cheating or plagiarism.  Any paper, assignment or examination showing signs of academic dishonesty will be investigated.  If I suspect dishonesty, I will notify the student that we must meet to discuss the matter.  Failure to respond to a request for such a meeting will be taken as an admission of guilt.  The standard penalty for dishonesty will be a grade of “0” on the assignment in question.  In egregious cases, I will give an “F” for the course grade.  In accordance with University policy, I will report any penalties levied to the vice chancellor for student affairs.  Penalized students then have the right to appeal.

 

Any work submitted by a student must be written in his or her own words (i.e. you cannot simply copy or paraphrase textbooks, other written sources, or work submitted by other students).  In the case of group work submitted with multiple names, I will assume that all have contributed equally.  For homework and problem sets, I encourage students to work together, but that cannot mean that one student simply copies from another. 

 

Recycled paper and two-sided printing

I encourage you to save paper by printing typed assignments on the back of previously used paper.  If you do this, I ask that you draw an “X” through the side I don’t need to read.  Alternatively, print your assignments on both sides of fresh paper.  Spreadsheets and graphs can be sent to me via e-mail, and if possible, I will refrain from printing them at all.

 

Extra credit policy

I may periodically offer extra credit as an incentive to participate in activities that are related to class, but not otherwise required—public lectures, service projects, etc.  Extra credit cannot be used to raise your final course grade more than one step—i.e. a C- to a C or a B+ to an A-.  Thus, any extra credit earned beyond 40-50 points will enrich your soul, but cannot enrich your grade.

 

Disability Accommodations

I will make reasonable accommodations for students with disabilities or special needs upon request.
