Text: Elementary Differential Equations and Boundary Value Problems, 10th Edition by Boyce and DiPrima. It is important and expected that you read the text, especially the examples.
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:
- acquire proficiency in quantitative methods for solving (systems of) differential equations;
- acquire proficiency in qualitative methods for interpreting and analyzing (systems of) differential equations;
- understand the conceptual aspects of the topics covered in Differential Equations;
- improve general problem solving skills;
- improve technical and quantitative reading ability;
- improve skills for acquiring technical and quantitative knowledge;
- improve technical and quantitative communication;
- improve skills required for working with a diverse group of individuals.
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.
- There will be daily homework, due at the beginning of class (excluding exam days). Homework will be posted on Pioneerweb and Gradescope after each class. There will be two types of problems listed on an assignment:
- HW: These four problems require a formal, written solution including explanations and/or justifications of applied concepts and techniques. These are the only problems submitted for grading.
- Recommended: These problems are part of the homework assignment and should be completed. They are not submitted and therefore not graded.
- You and your partner should submit ONE, JOINT, written assignment. If a scheduling conflict occurs, or you disagree on the solution to a problem, you may submit individual assignments with an explanation. Submitting one, joint assignment is expected and submission of individual assignments should be unusual.
- Homework will be submitted via Gradescope. A link to our Gradescope page is available on the Pioneerweb page.
- Solutions to problems should be written in complete sentences and include an explanation of the techniques used to solve a problem.
- The two lowest homework scores will be dropped.
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).
- You will submit HW via Gradescope.
- Only submit the four problems marked HW. Do not submit other problems.
- Number your homework problems.
- The problems should appear in your homework in the same order they appear on the assignment. A problem that appears out of order will likely not be graded. (You will designate the locations of the problems during Gradescope submission.)
- Do not divide your pages into columns; rather work entirely across the page so the problems appear in order.
- Turn in neat homework, with legible calculations that are large enough to be read.
- You do not need to compute decimal approximations for your solutions unless explicitly requested in the problem. For example, square roots and trigonometric functions may be perfectly acceptable answers.
- Homework submitted after the beginning of class but on the same day will be reduced by 3 points.
- No homework will be accepted after the due date unless arranged in advance.
- When one partner is not able to participate in completing the HW, individual assignments have the same due date and time requirements.
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.
- Wednesday, February 17;
- Monday, March 8.
The final exam is scheduled for Tuesday, March 23, 9:00am - 12:00pm. The final exam is three hours and will be comprehensive.
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.
