Learning Goals:

The course content is clearly a critical component of Differential Equations. The course also has supplementary learning goals regarding problem solving skills, interacting with technical and quantitative material, and working with peers. The learning goals for this course are:


The College credit hour equivalence for the 7.5 week terms requires us to perform approximately 24 hours of course related work per week. This includes interacting with class meetings, reading, working on problems with and without your weekly partner, asking and answering questions on Piazza, writing solutions, studying, and completing exams. The take away message here is that you should expect to dedicate roughly 24 hours per week to the course.


A significant course goal is developing the skills to work in a group toward a mutual comprehension of the material. Students will be randomly assigned a weekly partner. You and your partner will occasionally work to answer a question during class meetings. Most importantly, you and your partner will work together on the daily homework assignments.


Especially in our online environment, it is critical to your learning, the learning of your peers in class, and the overall experience of everyone that we are engaged with the course. Participation will be a portion of the course grade. You will demonstrate active participation by attending and participating in the class meeting (synchronous online class sessions), meeting with and studying with your weekly partner, engaging with class members on Piazza (asking and answering questions in our online discussion board), attending office hours (online meetings with the Professor), completing assignments, etc.


Instructions for Preparing and Submitting Homework:

The homework must be legible and organized to be graded. Follow these guidelines:

The homework is due at the beginning of class: 8:30 am (US Central Time).

Midterm Exams:

There will be two in-class, midterm exams tentatively scheduled for These midterm exams will test the material covered since the previous exam. The exams are timed. When you begin the exam, you will have a specified amount of time to complete and submit the exam.

Final Exam:

The final exam is scheduled for Tuesday, March 23, 9:00am - 12:00pm. The final exam is three hours and will be comprehensive.
Course Grade:
Participation: 10%
Homework: 25%
Midterm Exams: 40% (20% each)
Final Exam: 25%

Academic Honesty:

All students must be aware of and comply with the Grinnell College Academic Honesty policy.

In this course students may collaborate on homework assignments with their assigned partner. All work should be the creation of the students. If one partner does not participate on a specific homework, submit individual assignments. It is expressly forbidden to look for solutions online, in other textbooks, or from other students. It is also an academic honesty violation to solicit assistance from any online forum other than our class discussion board.

The midterm and final exams are individual endeavors. Students may not consult other students, family, friends, nor the Internet during the exam. Students MAY consult the textbook, posted lecture notes, and their own notes and homework.


Attendance at online course meetings and arranged study sessions with your weekly partner is expected. In addition to impacting the participation portion of the course grade, excessive absences may result in a reduction in the final letter grade.


If you are in need of specific learning accommodations, please let me know early in the semester so that your learning needs may be appropriately met. If you have not already done so, you will need to provide documentation to the Coordinator for Disability Resources, Autumn Wilke, located on the 3rd floor of the Rosenfield Center (x3702) and discuss your needs with her.
