Math 250 Linear Algebra

Homework will be due two times per week, generally Tuesdays and Fridays. It will be due at 3:00 pm on the due date. All homework assignments are posted on the webpage MATH 250 Assignments. Part of doing homework is reading the text. The text contains additional examples and material that may be relevant for homework and quizzes. All homework may be rewritten for full credit. All rewrites are due one week following the original due date. Late homework will be accepted within one week the due date. Note that the rewrite deadline is firm, so late homework may not be eligible for rewriting.

At the start of each section, there is a “Preview Activity.” You are required to complete these BEFORE we start the section. To get credit, you need to complete these in Runestone. They are not graded for accuracy, but just for completion. Since the point of these questions is to be prepared for class, you will only get credit if they are completed within 24 hours from when we start the section.

Also in Runestone, there are PROTEUS Questions. These questions are part of an NSF grant project. The grant and the necessary consent forms will be discussed in class. You are not required to be part of the grant, however, the PROTEUS questions are still required as part of your grade. As with the Preview Activities you will only be graded on completion of the questions. The due dates for the PROTEUS Questions will be the same as the Homework for the section and will have the same late policy as the homework.

Due dates for Preview Activities correspond to start dates for the sections as found in the Daily Schedule

Due dates for the PROTEUS Questions correspond to the Homework due dates as found on MATH 250 Assignments.

There will be six quizzes. The quizzes will be completed in class. You may use Sage for some computations. The quizzes are every two weeks. You may retake any quiz. It is recommended that make-up quizzes be completed within one week. The final deadline to retake a quiz is 3 pm on Reading Day, Friday, May 22. Each quiz may be retaken only once.

At the start of each module, you will take a multiple choice assessment (iRAT) based on assigned material. After submitting you answers, you will work with your team on the same assessment (tRAT), submitting team answers. Your scores on both the iRAT and the tRAT will be averaged for your RAT score. If you are unable to be at class for the RAT process, you may take the iRAT before the next class period. Your iRAT will stand as your score. If you miss a RAT and are unable to make it up before the next class, I will drop one RAT score.

Each section will have several activities that you will work on with your team. You will work in groups of 4-6 students on the activities. You will not be assessed on your team’s specific answers to the activities, but you will be assessed on your general engagement with your team. This includes attendance, participation, and teamwork. There will be both a peer evaluation score and a faculty evaluation score. If you are unable to be in class, it is your responsibility to check with your team about what activities you missed.

Over-reliance on AI tools to do mathematics is often a replacement for doing mathematics with other people. This can impact your ability to learn, evaluate, and communicate mathematics. Evidence of such use will affect your community grade. See the AI statement for the specifics of appropriate uses for this course.
