Course Information

Course Catalog Description

Treatment of ordinary differential equations with applications. Topics include: first-order equations, first-order systems, linear and non-linear systems, numerical methods, and Laplace transforms. Computer-aided solutions will be used when appropriate.

Prerequisites

The prerequisite for this course is MATH 222 Calculus III. Implicit in this is that students enrolled in the course should also have a mastery of Calculus I and II. In particular, students should be proficient in computing limits, derivatives, and integrals using techniques including but not limited to u-substitution, integration by parts, partial fractions, and trigonometric substitution. A solid grasp of Taylor series is also beneficial. Students should be able to independently look up or review calculus techniques when necessary.

Student Learning Outcomes and Assessment

Table 1: Course outcomes and assessment.

After taking this course, the student should be able to: Methods of assessment
Recognize and explain what is meant by a differential equation as a mathematical model for a phenomenon, and understand the meaning of a solution to an ODE and an initial value problem. Homework assignments, DE model project, and in-class written exams.
Recognize and solve separable equations; recognize and solve basic first- and second-order constant-coefficient linear differential equations; and apply Laplace transform methods to solve differential equations. Homework assignments and in-class written exams.
Analyze by a variety of methods—including graphical, qualitative, and numerical—first- and second-order nonlinear autonomous differential equations and systems. Homework assignments and in-class written exams.
Recognize and interpret differential equation models arising from applications in science, engineering, and the biosciences. Homework assignments and DE model project.

Course Policies and Procedures

Attendance

It is important that you attend class regularly and participate actively by asking and answering questions during lecture. If you must miss class for any reason, it is your responsibility to notify the instructor as soon as possible and make arrangements to quickly make up any content or assignments missed due to absence.

Use of AI

Artificial intelligence (AI) can be an effective tool in science and engineering. For example, generative AI platforms like Copilot, Claude, or ChatGPT now help programmers to write better code in less time. Learning to use AI effectively and responsibly is quickly becoming a basic skill for the modern scientist. Because of this, I do not want to completely discourage the use of AI assistance.

However, I insist that you avoid using AI platforms or tools in a manner that is inappropriate in the context of this course. This course teaches a variety of concepts, skills, and problem solving. Using AI in such a way as to avoid learning, developing skills, or problem solving is not appropriate. If you find yourself using AI to look up answers, search for complete solutions to problems, or things like this, then your use of AI is not acceptable.

It might be helpful to think of AI as an analog to a calculator. If the goal of an assignment is for you to demonstrate that you can do a certain calculation, then using a calculator is not appropriate. On the other hand, if the goal of an assignment is for you to demonstrate that you can solve a problem for which a minor step involves doing a calculation, then using a calculator is okay. AI use in the context of this course should be treated analogously.

In particular, it is expected that students will be able to explain independently and in detail any work or ideas on assignments this semester. If you have any doubts about your use of AI, then either ask the instructor if your use of AI is acceptable or just don’t use AI.

Assignments

Homework

There will be regular homework assignments posted on the course learning management system. The homework assignments will be made up of problems relating to or extending the material covered in lecture and assigned readings.

Students are permitted (in fact, encouraged) to collaborate on the homework assignments. Note that collaboration in this context means a roughly equal amount of contribution from all parties involved. Thus, asking another student to show you how to do a complete problem is not collaboration and constitutes copying the work of someone else, which is academic dishonesty. On submitted homework, please identify for each problem who you worked with. All homework problems (with the exception of computer code) must be submitted as a hard copy in your own handwriting. Looking up solutions to homework problems online is academic dishonesty. Of course, all students are always welcome and encouraged to seek out help from the course instructor for solving homework problems.

Extensions on homework must be requested in writing via email no less than 24 hours before the assignment is due. No extension greater than 2 business days will be granted except in rare circumstances. Homework assignments for which an extension is granted should be submitted electronically via email to the instructor.

Do not underestimate the value (and joy) of carefully working through homework problems.

DE Model Project

The differential equations model project (link to guideline) is an assignment designed to assess students’ understanding of differential equations as mathematical models for scientific or other phenomena. In addition, this assignment assesses the students’ ability to effectively communicate mathematical ideas in the context of differential equations. Guidelines and a rubric for this assignment will be posted on the course learning management system.

Exams

The in-class exams are meant to assess 1) students’ understanding of the material covered in class and in homework assignments, 2) students’ understanding of the core concepts, 3) students’ problem solving abilities, and 4) students’ ability to think independently. You may use a non-programmable scientific calculator on exams. If you wish to use a calculator on an exam, you must bring your own. (If you provide the instructor with sufficient advanced warning (at least two days), they may be able to assist you in acquiring a calculator for use on an exam.) You may not share calculators during exams. You may not use a cell phone as a calculator during exams. You may not use any other electronic device during exams.

If you must miss an in-class exam, you are required to notify the instructor via email at least 24 hours before the exam or as soon as possible in the case of an emergency. Acceptable reasons for absence include but are not necessarily limited to medical emergencies, serious illness, family emergencies, religious observances, and participation in university-sanctioned events. You must provide appropriate documentation to substantiate your reason for the absence. If your absence is excused, you will be allowed to take a make-up exam scheduled within one week of the original exam date.

Write Your Own Exam Problems

In order to encourage active participation in the learning process, the instructor invites all students to submit suggested problems to appear on each exam. On any given exam, any individual student is welcome to submit up to two problems for consideration. Submissions must be made a minimum of three days before the exam. Along with a clear statement of the problem must appear a carefully, clearly, and correctly written solution. Any problem submission, along with its solution, will be copied and handed out to the rest of the class at least one day before the exam. Students will not know in advance if their problem has been chosen to appear on the exam. The instructor is under no obligation to use any or all submitted problems. However, the more problems that students submit, the greater the chances that some will be chosen to appear on an exam.

Academic Honesty and Integrity

Each student is expected to do their own work. It is also expected that each student respect and abide by the Academic Code of Honesty as set forth in the University of Scranton student handbook. Conduct that violates the Academic Code of Honesty includes plagiarism, duplicate submission of the same work, collusion, providing false information, unauthorized use of computers, theft and destruction of property, and unauthorized possession of tests and other materials. Steps taken in response to suspected violations may include a discussion with the instructor, an informal meeting with the dean of the college, and a hearing before the Academic Dishonesty Hearing Board. Students who are found to have violated the Code will ordinarily be assigned the grade F by the instructor and may face other sanctions. The complete Academic Code of Honesty is located on the University website at https://www.scranton.edu/academics/wml/acad-integ/acad-code-honesty.shtml.

My Reporting Obligation as a Responsible Employee

As a faculty member, I am deeply invested in the well-being of each student I teach. I am here to assist you with your work in this course. Additionally, if you come to me with other non-course-related concerns, I will do my best to help. It is important for you to know that all faculty members are required to report incidents of sexual harassment or sexual misconduct involving students. This means that I cannot keep information about sexual harassment or discrimination, sexual assault, sexual exploitation, intimate partner violence or stalking confidential if you share that information with me. I will keep the information as private as I can but am required to bring it to the attention of the University’s Title IX Coordinator, Elizabeth M. Garcia, or Deputy Title IX Coordinator, Diana M. Collins, who, in conversation with you, will explain available support, resources, and options. I will not report anything to anybody without first letting you know and discussing choices as to how to proceed. The University’s Counseling Center (570-941-7620) is available to you as a confidential resource; counselors (in the counseling center) do not have an obligation to report to the Title IX Coordinator.

About Pronouns

It is easy to make assumptions about an individual’s pronouns, but we try not to! Please inform the instructor either in class or via a private email if you would like to share your pronouns, if/when you would like the instructor (and others) to use them, and certainly feel free to correct the instructor or others if a mistake is made. Using the pronouns that a person has indicated they prefer is considered both professional and polite, and as such we ask that all members of our class use the appropriate pronouns.

If you have questions about this, please feel free to look up more information at https://www.mypronouns.org/ or email with any questions.

Student Mental Health: Suggestions and Resources
