Course Goals

Learning Outcomes:  Upon successful completion of Math 338 - Topology, a student will be able to:

    Your grade in this course will be based on presenting problems in class, problem sets and one research project. Problem sets will be worth 13/20, the project 1/5, and presentations worth 3/20. 

Student Presentations
    Every two weeks ending on Wednesdays, each student must present at least one problem.  Problems are to be selected from the material for that day's section(s).  Discussing problems with classmates or me is highly endorsed.  Presentations will be scored out of at most 4 points.  The class presentations will be graded roughly as follows:
4    excellent
3.5 very good - at most minor errors
3    some problems, but the main idea of the solution is clear
2    some correct things
1    attempted
0    no presentation
    I will determine priority for presenting problems.  Each student who has not yet presented will have priority over students who have presented.  A second (or more) problem may be presented in order to replace a prior presentation.   

Problem Sets
    Problem sets will consist of 5-10 questions related to material presented in the previous two weeks.  They will be due two weeks after assigned.  They will consist of assigned problems not presented by students in the prior two weeks.  Before these papers are handed  in,  I strongly suggest discussing them with me and others outside of class.   Each problem will be graded on a ten point decile scale based on completeness, accuracy, and writing.
    These problems will be evaluated as follows.
0    missing
3    question copied, nothing written
6    something written that appears that it was only written to take up space
7    substantially incomplete.  Something written,  but does not really answer the main questions.  Major errors. Very poor writing
8    mostly complete. maybe a few minor errors
9    complete, no errors, some personal insight, well-written
10  wonderful
    No late problem sets will be accepted.

Solutions and Plagiarism
    There are plenty of places that one can find all kinds of solutions to problems in this class.  Reading them and not referencing them in your work is plagiarism, and will be reported as an academic integrity violation.  Reading them and referencing them is not quite plagiarism, but does undermine the intent of the problems.  Therefore, if you reference solutions you will receive 0 points, but you will *not* be reported for an academic integrity.  Simply - please do not read any solutions for problems in this class. 

Final Project
    You will write a 1200-2000 word research paper on a topology topic not covered in class.   Selecting the topic by the deadline will be worth 5%, annotated bibliography will be worth 15%, the draft will be worth 20%, the 10-12 minute presentation will be worth 20%, and the final paper will be worth 40%.

   Occasionally you will be given anonymous feedback forms.  Please use them to share any thoughts or concerns for how the course is running.  Remember, the sooner you tell me your concerns, the more I can do about them.  I have also created a web-site which accepts anonymous comments.  If we have not yet discussed this in class, please encourage me to create a class code.  This site may also be accessed via our course page on a link entitled anonymous feedback.  Of course, you are always welcome to approach me outside of class to discuss these issues as well. 

    SUNY Geneseo is dedicated to providing an equitable and inclusive educational experience for all students. The Office of Accessibility will coordinate accommodations, auxiliary aids, and/or services designed to ensure full participation and equal access to all academic programs, activities, and services at SUNY Geneseo. Students with letters of accommodation should submit a letter and discuss needs at the beginning of the semester. Please contact the Office of Accessibility Services for questions related to access and accommodations.  Erwin Hall 22 (585) 245-5112

Religious Holidays
    It is my policy to give students who miss class because of observance of religious holidays the opportunity to make up missed work.  You are responsible for notifying me no later than September 12 of plans to observe the holiday.  

Military Obligations
    Federal and New York State law requires institutions of higher education to provide an excused leave of absence from classes without penalty to students enrolled in the National Guard or armed forces reserves who are called to active duty. If you are called to active military duty and need to miss classes, please let me know and consult as soon as possible with the Dean of Students.
