Learning Outcomes

By their efforts in this course, students should improve in the following course learning outcomes: linear systems, vector spaces, linear transformations, augmented matrices, Gaussian reduction, vector equations, matrix equations, linear independence, affine geometry, subspaces, bases, coordinates, matrix operations, matrix inverses, elementary matrices, matrix factorizations, matrix representations, inner products, orthogonality, outer products, affine transformations, orthogonal projections, the Gram-Schmidt algorithm, least squares, determinants, Cramer's rule, cross products, eigenvalues,  eigenvectors, characteristic polynomials, diagonalization, similarity

Additionally, students will improve in the following university Essential Learning Outcomes: Quantitative Literacy, Problem Solving, Communication, and Critical Thinking.

Course Requirements

Your final grade will be determined by your acquisition of points throughout the course. Points are rewarded based upon your engagement in learning activities and positive performances on course assessments, as outlined below. If x is the number of points earned, then letter grades will be assigned based upon x according to the following bounds:
A: x ≥ 930 pts                A-: 900 ≤ x < 930 pts     
B+: 870 ≤ x < 900 pts    B:  830 ≤ x < 870 pts     B-: 800 ≤ x < 830 pts     
C+: 770 ≤ x < 800 pts    C: 730 ≤ x < 770 pts      C-: 700 ≤ x < 730 pts
D+: 670 ≤ x < 700 pts    D: 630 ≤ x < 670 pts      D-: 600 ≤ x < 630 pts     
F: x < 600 pts

A grade of UW (unofficial withdrawal) will be assigned to students who have no course engagement after the official withdrawal deadline for this course, which is 21 May 2026.

There will be four types of assignments collected in this course:
Homework - 250 points - typically one pt per lesson and five pts per homework
Exams - 750 points - three unit exams (250 pts each)

More specific details about how to complete assignments and their due dates can be found on Canvas.

Instructor's policies on late assignments and/or makeup work

All graded assignments have a due date posted on Canvas. Students are expected to submit all of their work by these due dates. All assignments will be submitted via Canvas. After each due date, Canvas will lock the submission of that assignment. For this reason, it is important to submit all assignments on time.
Understanding there is a need for reasonable accommodations to strict due dates, the following late policy applies to all course assignments. If a foreseeable event prohibits your ability to submit an assignment by its due date, then it is your responsibility to email Dr. Misseldine before the assignment's due date to explain the situation and request an extension. If requested before the due date, then nearly all extensions will be granted. If requested after the due date, the extension is most likely to be denied. Of course, in the situation of an unforeseeable event, such as illness or emergency, you are expected to email Dr. Misseldine as soon as you reasonably can to explain the situation and request an extension. All university-approved absences and extensions will be approved if requested before the due date. Late work submitted without approval will receive no credit. No student work will be accepted after 26 June 2026, and work cannot be submitted after the grading of the final exam to improve a final grade.
Note that the above procedure should only be used rarely as there is no substitute for timely submission of work. Students who need to submit more than occasional late work will need to schedule a conference with Dr. Misseldine to discuss the concern and design an accommodation and responsibility schedule to serve the best needs of the student within university policies. 

Attendance Policy

This is an asynchronous course, that is, attendance is not required at any time. If ever there are live events throughout the term all students are invited to attend, but attendance is optional.

Course Fees

$3.75

ADA Statement

Students with medical, psychological, learning, or other disabilities desiring academic adjustments, accommodations, or auxiliary aids will need to contact the Disability Resource Center, located in Room 206F of the Sharwan Smith Center or by phone at (435) 865-8042. The Disability Resource Center determines eligibility for and authorizes the provision of services.

If your instructor requires attendance, you may need to seek an ADA accommodation to request an exception to this attendance policy. Please contact the Disability Resource Center to determine what, if any, ADA accommodations are reasonable and appropriate.

Academic Credit

According to the federal definition of a Carnegie credit hour: A credit hour of work is the equivalent of approximately 60 minutes of class time or independent study work. A minimum of 45 hours of work by each student is required for each unit of credit. Credit is earned only when course requirements are met. One (1) credit hour is equivalent to 15 contact hours of lecture, discussion, testing, evaluation, or seminar, as well as 30 hours of student homework. An equivalent amount of work is expected for laboratory work, internships, practica, studio, and other academic work leading to the awarding of credit hours. Credit granted for individual courses, labs, or studio classes ranges from 0.5 to 15 credit hours per semester.

Academic Freedom

SUU is operated for the common good of the greater community it serves. The common good depends upon the free search for truth and its free exposition. Academic Freedom is the right of faculty to study, discuss, investigate, teach, and publish. Academic Freedom is essential to these purposes and applies to both teaching and research.

Academic Freedom in the realm of teaching is fundamental for the protection of the rights of the faculty member and of you, the student, with respect to the free pursuit of learning and discovery. Faculty members possess the right to full freedom in the classroom in discussing their subjects. They may present any controversial material relevant to their courses and their intended learning outcomes, but they shall take care not to introduce into their teaching controversial materials which have no relation to the subject being taught or the intended learning outcomes for the course.

As such, students enrolled in any course at SUU may encounter topics, perspectives, and ideas that are unfamiliar or controversial, with the educational intent of providing a meaningful learning environment that fosters your growth and development. These parameters related to Academic Freedom are included in SUU Policy 6.6.

Academic Misconduct

Scholastic honesty is expected of all students. Dishonesty will not be tolerated and will be prosecuted to the fullest extent (see SUU Policy 6.33). You are expected to have read and understood the current SUU student conduct code (SUU Policy 11.2) regarding student responsibilities and rights, the intellectual property policy (SUU Policy 5.52), information about procedures, and what constitutes acceptable behavior.

Please Note: The use of websites or services that sell essays is a violation of these policies; likewise, the use of websites or services that provide answers to assignments, quizzes, or tests is also a violation of these policies. Regarding the use of Generative Artificial Intelligence (AI), you should check with your individual course instructor.

Emergency Management Statement

In case of an emergency, the University's Emergency Notification System (ENS) will be activated. Students are encouraged to maintain updated contact information using the link on the homepage of the mySUU portal. In addition, students are encouraged to familiarize themselves with the Emergency Response Protocols posted in each classroom. Detailed information about the University's emergency management plan can be found at https://www.suu.edu/emergency.

Mandatory Reporting

University policy (SUU Policy 5.60) requires instructors to report disclosures received from students that indicate they have been subjected to sexual misconduct/harassment. The University defines sexual harassment consistent with Federal Regulations (34 C.F.R. Part 106, Subpart D) to include quid pro quo, hostile environment harassment, sexual assault, dating violence, domestic violence, and stalking. When students communicate this information to an instructor in-person, by email, or within writing assignments, the instructor will report that to the Title IX Coordinator to ensure students receive support from the Title IX Office. A reporting form is available at https://cm.maxient.com/reportingform.php?SouthernUtahUniv
