Class Meeting TimesTuesday, Thursday 9:30 a.m. - 10:45 a.m. in Young 402B. This course

                                   counts 3 hours credit.


Test Dates: To be announced (There will be two major tests and a final exam).

Final Exam Date:  Tuesday, December 12th at 10:15 a.m. in Young 402B.


Grading Policy: 44 % 2 Major Tests 

                           22 % Final Exam

                           20 % Hand written Homework, Computer Assignments

                           7 %   Term Paper*

                           7 %    D2L Cryptography Discussion Participation**


* The term paper will be a short paper (4 pages) describing a person or cryptographic method pertaining to cryptology. I will give you a handout later this semester showing possible topics. I must approve the topic you choose. The paper should be typewritten (using Microsoft Word, for example) using 1.5 line spacing and should have good grammatical structure with references clearly stated. Do not plagiarize! The term paper will be due on Thursday November 30th.          


** For this part of the grade, you will be required to participate in Desire2Learn (D2L) discussion groups. This discussion will include you communicating with your classmates in groups (preferably using the wireless capabilities of your laptop) in a secret manner using some of the cryptographic techniques we study in class. You will have the opportunity to encrypt and decrypt your own messages and to break messages sent by others.

                        A “-” grade will be awarded at the discretion of the instructor

Prerequisite: High School Algebra, Honors Academy membership or permission of instructor.


“Makeup” Test Policy: Approval for making up a missed test should be given prior to the scheduled test. The makeup test must be taken within one week following the scheduled test. Documentation is required for all make-ups. Except for extraordinary circumstances, approval for a makeup test will not be granted if the scheduled test has already been given.


Late Homework Policy: Late hand written homework will be accepted but only limited credit will be given. I consider late homework to be homework turned in later than 5:00 p.m. of the day the assignment is due. The maximum number of points a student can receive for a late homework is ten points lower than the minimum grade of all students who have turned in the assignment on time. For example, if an assigned homework is worth 80 points and the lowest score of the on-time assignments is 60/80, the maximum grade a student can receive for the assignment is 50/80. No exceptions to this policy will be granted except for extreme circumstances that require official university documentation or a predetermined arrangement between the student and myself that is done prior to the assignment due date. Late assignments must be turned in within one class day of the assignment due date to obtain any credit. 


Attendance Policy:    Attendance is a requirement in this class. If you miss a class, you are responsible for making up any missed work. Attendance will be taken each class period. Attendance means RESPONSIBILITY – I look much more favorably on students who have good attendance habits.


Laptop/Cell Phone/Electronic Device Policy: No cell phones, computers, or other electronic devices are to be used in this class when these devices are not being used in a way that is conducive for learning what is being taught in class during a particular day or time. Determining what is conducive will be left up to the instructor's discretion. The instructor retains the right to ask a student to leave class if they exhibit this or any other behavior that is a distraction to learning for other students in the class.


Catalog Course Description: An introduction to the application of mathematical ideas for Honors students. Topics vary. This course can be taken more than once with different topics. This course has been approved for credit in the Mathematical Sciences of the Core Curriculum.


Student Goals and Objectives of the Course: Students should gain a deeper understanding and appreciation for mathematics and its applications, and some skill in addressing the particular types of quantitative issues included in the course. Math 132 concentrates on applications. Applications likely to be treated—cryptology is an example—are those which are interesting to many people, can be profitably approached using only elementary mathematics, and reward careful study with deepened understanding and appreciation of the power and beauty of mathematics.

Students will be able to use the tools of mathematics and quantitative reasoning to conceptualize and solve problems. Students will be able to:

a. identify and interpret relationships among numeric, symbolic, and graphical information
b. generate mathematical models using numeric, symbolic, and graphical information for use in
    real-world applications
c. solve problems using numeric, symbolic, and graphical information.

Disability Policy: Students seeking academic accommodations under the Americans with Disabilities Act must register with the Center for Accessibility Services (CAS) to determine eligibility. Students qualified for academic accommodations will receive accommodation letters and should meet with each course professor during office hours, to review and discuss accommodations.  To begin the registration process, complete a Student Registration Form and submit documentation to PO Box 6902, Radford, Virginia 24142, or deliver to the Russell Hall, Room 325, by fax to 540-831-6525, or by email to (See documentation guidelines).  For more information, visit the Center for Accessibility Services (CAS) website or call 540-831-6350.

Honor Code: By accepting admission to Radford University, each student makes a commitment to understand, support, and abide by the University Honor Code without compromise or exception. Violations of the University Honor Code include (but are not limited to): lying, stealing and unauthorized possession of property, cheating, multiple submission, and plagiarism. This class will be conducted in strict observation of the honor code. Refer to your Student Handbook for a complete copy of the University Honor Code.
