Foundations and Structure of Mathematics 1  Fall 2004

COURSE: MATH 5025
TIME: 5:00 p.m.  8:00 p.m. Tuesday
PLACE: Executive Auditorium of the Higher Education Center at Virginia Highlands Community College
INSTRUCTOR: Dr. Robert Gardner
OFFICE: Room 308G of Gilbreath Hall at ETSU

TEXT: The text for this course is The Heart of Mathematics: An Invitation to Effective Thinking, 2nd Edition, by E. B. Burger and M. Starbird, Key College Publishing, 2004. The first edition is also acceptable (the text in the sections we will cover is virtually identical from the first to the second edition, but some of the pictures are different). You can order a copy of the first edition from www.Amazon.com for around $49 postage paid (see the Amazon site for this book for details). I will refer to the "manipulatives kit" but you don't need to buy it. I will have 3D glasses available for each of us when we cover the sections which require them. I will also try to find some of the manipulatives (which involve cutouts) online for you to download.
ABOUT THE COURSE: This course (as well as the others in the ETSU program for elementary and middle school teachers in southwest Virginia) will be consistent with NCATE/NCTM standards and be guided by the "PUFM" philosophy ("Profound Understanding of Fundamental Mathematics"). Performance based assessment will be used to modify instruction as needed.
CLASS WEBPAGE: A webpage for this class is available at:
http://www.etsu.edu/math/gardner/5025/silfall04.htm
Although we will use Blackboard in this class, the majority of material available to you online will be accessible through this website.
BLACKBOARD: A Blackboard site is available for this class. We will use it primarily for "Discussions." I will use this site to communicate with you as a group, so it is important that you have the email address you normally use as part of your "profile" in Blackboard.
GRADING: Grades will be based on student performance on written homework assignments (HW),
a written report combined with inclass oral presentation (RO),
and class participation (CP, which will include inclass discussion and individual student presentation of homework problems) as follows:
AVERAGE = (HW + RO + CP)/3.
Grades will be assigned on a 10 point scale with "plus" and "minus" grades being assigned as appropriate (up or down 3 points, as is consistent with the grade points assigned to plus and minus grades by ETSU).
WRITTEN HOMEWORK ASSIGNMENTS: Two or three written problems will be assigned each class period and collected during the next class. These problems will be graded for accuracy and returned during the following class meeting.
INCLASS HOMEWORK PRESENTATIONS: A student will be selected to present each written homework problem in class (with access to their written solution). Each student is expected to present at least one problem during the term. If necessary, second chances will be given.
CLASS PARTICIPATION: I will lecture on each topic or present a video. We will then, as a group, discuss the topic at hand. Each student is expected to participate in some of the discussions. We will also carry on discussions through Blackboard. Each student is expected to post comments on Blackboard at least three times.
WRITTEN REPORT: A written report of at least five pages in length will be turned in some time near the end of the term. A number of suggested topics will be given on the class webpage (see below) and you should get your topic approved by the instructor before getting too involved in your project. It is expected that each report will include mathematical content (for example, if one were to do a report on Rene Descartes, then the report should include a discussion of his contributions to mathematics and their influence on future mathematical development). The written report will be due on November 30!!!
ORAL PRESENTATION: Each student will give an inclass presentation of roughly 10 minutes in length on his/her written report. The last three class days will be devoted to student presentations.
Your instructor will be quite impressed with multimedia presentations (assuming we have access to the appropriate equipment). Alternatives to an inclass presentation will be considered!!! Make a proposal to the instructor. Presentations will be given during the last two class meetings (November 30 and December 7).
