Purpose:

The purpose of this course is to introduce biology students to the fundamental

concepts that underlie the process of evolution.  Students will learn how this

discipline is relevant to all aspects of biology from the level of the molecule to

the level of the ecosystem. 

Office Hours:

Dr. Etterson - immediately after class on T and Th or by appointment

Matt Jahnke - Mondays 10:00-11:00 and Thursdays 11:00-12:00.

Lecture:

2:00-3:15, T and Th, 175 Life Science Building

Text:   

Evolution, 2nd Edition by Douglas J. Futuyma (2009).  Lectures will also include the figure numbers from the 1st edition of this text.

Software:

EvoBeaker SimBiotic software disk and workbooks from UMD bookstore.  You must purchase this packet.  When exercises are turned in to be graded, the original publisher’s workbook must be submitted. Photocopies will not be accepted.

Populus - simulations of population biology (D. N. Alstad, U of MN, 2007), is available for free download at http://www.cbs.umn.edu/populus

Readings:

Articles from the primary literature are listed on syllabus and can be downloaded if you would like to follow up on a topic of interest.

Attendance:

Attendance is expected.  Activities conducted during class periods will be considered in the computation of your final grade.  Unexcused absences from any exam will result in a grade of zero.

EvoBeaker Software & Workbooks:

Check out this recent NPR story on the ineffectiveness of the traditional lecture for student learning and you will begin to understand my rationale for the unusal format for this course.  Rethinking the way college students are taught

Lectures don't work!

We will use five EvoBeaker computer simulation exercises in this course to deepen your understanding of evolutionary concepts.  These exercises were developed with funding from the National Science Foundation to help introduce evolutionary thinking and provide opportunities to develop your skills in hypothesis generation and testing.  A packet is available in the bookstore which includes the software disk and workbooks for each simulation exercise. 

If you have a laptop, please bring it to class to submit answers to in-class simulation exercises and discussion questions.  We need one lap top for each 2-5 students to use in class for simulation exercises.  Students are free to change groups on a weekly basis.

 

There will be three kinds of assignments in the course (2 kinds of in-class assignments and one out-of-class weekly assignment):

In-class assignments - either 1. or 2. every class period : 

1.  Answer a problem in class

    • Etterson will project or pass out a problem on paper
    • Students will work in small groups (2-5 people) to solve the problem and upload their answer as a single file in Moodle. 
    • Only one upload is necessary per group but the names of all students who contributed to the answer must be clearly indicated at the top of the file.
    • Answers must be uploaded by 3:50 pm.
    • These answers will be graded by the TA and will be considered a component of "class participation." See grading matrix below.

2.  Answer a discussion question (a), peer review (b), and revise (c)

  • This is a three-part exercise that will be completed over the course of one week.

(a) On Tuesday in class Etterson will project a discussion question.

  • Students get into small groups (2-5 people) and write a short essay question directly into Moodle

(b) Between Tuesday at 4:00pm and Thursday at 2:00pm, each individual student will:

  • Open an answer in Moodle and write a short review of one of the other groups answers. Ttry to make one good substanative point (not spelling or grammar).  Each answer must get at least three reviews.  If a answer already has three reviews, then move on to the next one.

(c) On Thursday in class, the original Tuesday group will get back together and:

  • Rate the usefulness of the peer reviews they recieved. Tthese ratings will go into your Moodle gradebook and are considered a component of "class participation."  See grading matrix below
  • Rewrite the disucssion question answer taking peer reviews into consideration.
 

Outside of class:

3. Weekly Assignments

    • Students work in small groups to develop hypothesis, design experiments, and interpret their meaning following the instructions in the EvoBeaker packets. 
    • There will be an assignment from this group work due every week on Tuesdays that should be uploaded onto Moodle by 11:55 pm.Click here for uploading DIRECTIONS.Most of assignments will be the sythesis questions from the EvoBeaker workbooks.  Assignments should be prepared in a standard word processing program, like MS Word. 
    • A single group submission is encouraged.  Please clearly list all students who have participated in preparing the submission. 
    • These will be graded by the TA and will constitute 25% of your grade.

When we are finished with the exercises in the workbook:

  • Three times during the semester, you will be requested to turn in completed EvoBeaker workbooks that will be graded on a pass/fail basis (complete or not complete).  You must turn in the original publisher’s workbook at this time.  Photocopies will not be accepted.

 

Grading:

To calculate your final grade, the percentage of points obtained for each assignment and exam will be recorded, averaged across categories, and then weighted according to the table below.

Academic Dishonesty:

Academic dishonesty tarnishes UMD's reputation and discredits the accomplishments of students. UMD is committed to providing students every possible opportunity to grow in mind and spirit. This pledge can only be redeemed in an environment of trust, honesty, and fairness. As a result, academic dishonesty is regarded as a serious offense by all members of the academic community. In keeping with this ideal, this course will adhere to UMD's Student Academic Integrity Policy, which can be found at www.d.umn.edu/assl/conduct/integrity. This policy sanctions students engaging in academic dishonesty with penalties up to and including expulsion from the university for repeat offenders.

 

Student Conduct Code: 

The instructor will enforce and students are expected to follow the University's Student Conduct Code (http://www.d.umn.edu/assl/conduct/code). Appropriate classroom conduct promotes an environment of academic achievement and integrity. Disruptive classroom behavior that substantially or repeatedly interrupts either the instructor's ability to teach, or student learning, is prohibited. Disruptive behavior includes inappropriate use of technology in the classroom. Examples include ringing cell phones, text-messaging, watching videos, playing computer games, doing email, or surfing the Internet on your computer instead of note-taking or other instructor-sanctioned activities.

 

Access for Students with Disabilities:

It is the policy and practice of the University of Minnesota Duluth to create inclusive learning environments for all students, including students with disabilities. If there are aspects of this course that result in barriers to your inclusion or your ability to meet course requirements – such as time limited exams, inaccessible web content, or the use of non-captioned videos – please notify the instructor as soon as possible. You are also encouraged to contact the Office of Disability Resources to discuss and arrange reasonable accommodations. Please call 218-726-6130, 218-726-6130 or visit the DR website at www.d.umn.edu/access for more information.   

 

Promotion of Bias-free Instruction:

The University of Minnesota is committed to the policy that all of its students shall have equal educational opportunities. The University expressly forbids discrimination on the basis of race, color, gender, sexual orientation, disability, veteran's status, ethnicity, religion, creed, national origin or marital status. If you believe that your Biology instructor has not followed this policy, you are invited to bring this to the attention of the Biology Department Head (211 Life Science; 726-7263) or the Associate Dean of the College of Science and Engineering (140 Engineering; 26-7585). Your conference will be kept confidential.
