Welcome to MA 103! This course is designed to introduce you, the students, to applications of mathematics that lie outside of STEM fields and which have seen major innovations in the last century. The course also aims to expand your notions of what mathematics and mathematical reasoning entail and what sorts of fields they can be applied to, and to build your confidence in engaging with mathematical reasoning. This semester, we’ll be focusing on three main topics: voting theory, network analysis, and cryptography.
Course Description
(3 credit hours) Primarily for students in Humanities and Social Sciences. Illustrations of contemporary uses of mathematics, varying from semester to semester, frequently including sets and logic, counting procedures, probability, modular arithmetic, and game theory.
Prerequisite: MA 101 or equivalent completed in high school
GEP Mathematical Sciences.
Learning Objectives
You will be able to explain and apply foundational concepts in voting theory, network analysis, and cryptography, and you will be able to identify major recent innovations in these fields. You will also be able to explain how mathematics has impacted our understanding of these fields. And you will be able to engage with the mathematical practices of mathematical modeling, abstraction, example generation and analysis, and deductive reasoning as they pertain to these fields.
Course Structure
Lecture Materials
Your primary instruction for this online course will be through watching the lecture videos posted on the Moodle site. These videos were recorded by Dr. Stepan Paul from NC State specifically for this section of MA 103. They are organized into 26 lessons, each of which corresponds roughly to one class meeting (most lessons contain more than one video). The videos have embedded questions that you’ll need to answer along the way, which are designed to give you immediate practice with the material and keep you engaged with content. There are also Preview Questions for each lesson that should be completed before watching the corresponding videos. These are designed to get you thinking about the questions that will be addressed in the videos.
Live sessions
Our live sessions will be most Wednesdays at 2pm. They are optional to attend and will be recorded and posted on the course Moodle page. Please check Announcements for any changes or cancellations of weekly live sessions.
Communication and Getting Help
Forum
The course will use a Moodle Discussion Forum for asking and answering questions regarding the homework, exam preparation, and logistics. If you have a question, then one of your classmates may have already asked it on the forum; if not, you can make a new post. Students can answer each other’s questions, and instructors will monitor the forum regularly.
Contact me for confidential and private discussions about grades, scheduling office hours, etc. Please include MA 103 in the subject line. In general, I may not respond to messages outside of business hours (M-F, 9am-5pm), and it may take 24-72 hours for me to respond to an message. Math questions are generally best asked in office hours or on our forum, not by email.
Tutoring Centers
During the regular school year, there is free help available on campus for MA 103. See the following links:
- Math Tutoring Center (MTC) in SAS 2105. This room has many computers available so that you can work on your assignments. The room is a low-stress environment: you may work quietly in the room without engaging a tutor, or you may ask questions of the graduate tutors when they are available.
- Academic Success Center (ASC) in D.H. Hill Library has a few options:
For Drop-In Tutoring hours, notice the MTC is open during the day, and the ASC is open in the evening.
We encourage and expect you to work together with your classmates on homework assignments and studying, either remotely or in person.
Homework
Moodle Online Homework
You will have online homework assignments through Moodle. These will typically be due on Wednesday nights at 11:59pm. Please always check the assignments themselves, as the due dates are posted for each one.
Written Peer-Graded Homework
You will also have written assignments on Moodle. These are short answer questions that you’ll answer in paragraph form. You’ll have 1 or 2 of these per week. These will typically be due on Wednesday nights at 11:59pm, and the assessments will typically be due on Friday nights at 11:59pm. Late submissions are NOT allowed.
You are also responsible for doing a peer assessment for each other's work on Moodle. A rubric is provided for each question, and you’ll be assigned 4 other students’ responses to evaluate. You’ll get a grade based on both how your response is evaluated and on your evaluation of others. This process will be overseen by the instructional staff, and scores may be overridden. The purpose of this peer-grading system is to give you a chance to see what goes into quality responses on the homework so that you can be best prepared for the exams.
You should still complete the written problem assessment if you miss the corresponding written problem submission.
Test Information
Proctors
All examinations will be proctored through DELTA. You will either take your exam with DELTA, or coordinate remote proctoring with DELTA, according to which situation best describes you:
- If you live less than 50 miles away from Raleigh, NC, then you will take your tests on our campus through the Distance Education Testing Centers. Students should be mindful of closing hours for both Testing Centers, and give themselves plenty of time to complete their exams. For information, please visit DELTA on-campus testing services.
- Those students who live more than 50 miles away from Raleigh, NC do not have to take their tests on NCSU campus. They may use a proctor in their town for testing. The proctor must be approved in advance through DELTA (not the instructor). It can take up to 1 week to verify a proctor and set up all needed contact info, so please do this early! Please visit the remote proctor website at DELTA remote proctoring.
I encourage you to look through DELTA Testing Service's website, especially their frequently asked questions (FAQs).
Note: the word remote in this context means that you are using a professional testing site (for example, a testing center, a local library, a college, etc.) other than DELTA. Remote testing does not mean testing at home.
Quick Links
Please sign up your preferred time and date as soon as possible. Time slots fill up fast:
You may reschedule an exam appointment directly with DELTA using the link above. You do not need to contact the instructor for permission, provided that your new appointment is scheduled within the exam's posted date range.

Requirements for Credit-Only (S/U) Grading
In order to receive a grade of S, students are required to take all exams, complete all assignments, and earn a grade of C- or better. Conversion from letter grading to credit only (S/U) grading is subject to university deadlines. Refer to the Registration and Records calendar for deadlines related to grading. For more details refer to REG 02.20.15 - Credit-Only Courses.
It is the student's responsibility to check if an S grade gives progress towards their degree(s).
Requirements for Auditors (AU)
Information about and requirements for auditing a course can be found at REG 02.20.04 - Audits.
Policies on Incomplete Grades
NC State Policy
At the discretion of the instructor, students may be given an IN grade for work not completed because of a serious interruption in their work not caused by their own negligence. An IN must not be used, however, as a substitute for an F when the student's performance in the course is deserving of failing. An IN is only appropriate when the student's record in the course is such that the successful completion of particular assignments, projects, or tests missed as a result of a documented serious event would enable that student to pass the course.
If an extended deadline is not authorized by the instructor or department, an unfinished incomplete grade will automatically change to an F after either (a) the end of the next regular semester in which the student is enrolled (not including summer sessions), or (b) the end of 12 months if the student is not enrolled, whichever is shorter. Incompletes that change to F will count as an attempted course on transcripts. The burden of fulfilling an incomplete grade is the responsibility of the student. See the university policy on incomplete grades: REG 02.50.03 - Grades and Grade Point Average.
Course Schedule
The course schedule is tentative and subject to change. Adjustments may be made to accommodate the pace of the class and unforeseen circumstances. All major changes will be announced in class and posted on Moodle.
- Course Calendar: HTML
Important Dates
For holidays and other university closures, please consult the general NC State Academic Calendar.
Your final exam schedule is already determined; find it here: NC State Final Exam Calendar. You are responsible for reviewing your final exam sessions to arrange a suitable time for this course.

Additional Information
Student Expenses
There are no expected expenses for this course.
Late Assignments
Generally no late assignments are accepted in this course. Please plan your work carefully and submit assignments by their stated deadlines. Extensions may be occasionally granted by the instructor for extenuating circumstances, which are best documented with NC State Absence Verification.
For longer-term, recurring, or more serious illness or other interruptions to your participation in this class, you should reach out to your instructor as soon as you can.
Late Examinations
Excused absense. If an exam is missed with an excused absence (that is, for a university-approved reason with supporting documentation), then a make-up test will be scheduled individually. The make-up test may contain different questions and be assessed differently than the regular test. Documentation for an excused absence must be provided within 1 week of the missed class. All absences that require a make-up exam or other special accommodations must go through the NC State University absence verification process. Here is the link to that office: NC State Absence Verification.
Failure to schedule. You must schedule exams in a timely fashion to guarantee that you will be able to take them. It is the instructor’s discretion whether a make-up exam will be allowed if you are not able to schedule an exam appointment within the selected time frame. If the instructor approves a make-up exam, there may be a 10% penalty on that exam. The make-up test may contain different questions and be assessed differently than the regular test.
Other absences. If an exam is missed for an unexcused absence, that exam will be given a score of 0.
Attendance
Since this course is an asynchronous online course, there is no daily attendance. Instead, each student's participation in Moodle is tracked to check for regular activity. For complete attendance and excused absence policies, please see Attendance Regulations (NCSU REG 02.20.03).
Academic Integrity
Students are required to comply with the university policy on academic integrity found in the Code of Student Conduct (NCSU POL11.35.01). Your submission of any exam indicates "I have neither given nor received unauthorized aid on this test or assignment." Violations of academic integrity will be handled in accordance with the Student Discipline Procedures (NCSU REG 11.35.02).
Posting any course material to websites like Chegg, ChatGPT, and Course Hero is a violation of copyright law and course policy and is strictly prohibited. Violations of this policy will be reported to the Office of Student Conduct.
- Tests: Proctored tests are closed book assessments. You may not consult any internet resources nor receive help from anyone else. Do not share information about the content on the exams with anyone else in the class. See the calculator policy in the Test Information section of this syllabus.
- Homework: You may consult your notes, the textbook, each other, or online resources.
- Forum discussion boards: You are encouraged to discuss mathematical concepts and problems with your classmates. However, you must arrive at your own solutions with your own work. Do not seek nor state final answers on the forum; focus on understanding the concepts.

Course Evaluations
ClassEval is the end-of-semester survey for students to evaluate instruction of all university classes. The current survey is administered online and includes 12 closed-ended questions and 3 open-ended questions. Deans, department heads, and instructors may add a limited number of their own questions to these 15 common-core questions.
Each semester students' responses are compiled into a ClassEval report for every instructor and class. Instructors use the evaluations to improve instruction and include them in their promotion and tenure dossiers, while department heads use them in annual reviews. The reports are included in instructors' personnel files and are considered confidential.
Online class evaluations will be available for students to complete during the last two weeks of the semester for full semester courses and the last week of shorter sessions. Students will receive an email directing them to a website to complete class evaluations. These become unavailable at 8am on the first day of finals.
