Course Content

The course is split into five Modules, each of which is split into several Standards of learning.

In particular, our course standards are aligned with the following learning outcomes defined by the Association of American Colleges & Universities:

  • Convert relevant information into various mathematical forms (e.g., equations, graphs, diagrams, tables, words).

Textbook and Resources

Much of the material for this course will be provided on the course website or uploaded to Google Drive.

The textbook carried in the univeristy bookstore will not be required. A free online respository of homework exercises will be provided instead.

The use of any calculator is allowed on assessments, as long as it does not support communication functionality or internet connectivity.

Grading

Grades in this course are determined based upon your mastery of the Course Standards. Each time you successfully demonstrate mastery of a Standard by correctly completing a relevant exercise/project, you will earn a Mastery Mark ✓. Up to two ✓ per Standard will be awarded for the 16 non-modeling standards, and one ✓ per Standard will be awarded for the 8 modeling standards, for a maximum of 40 ✓.

Letter grades are assigned based on how much content was learned by each student, measured by how many ✓ were earned.

  • A: 38✓
  • B: 33✓
  • C: 28✓
  • D: 23✓

Student Data

Grade data will be provided to students via regular printed progress reports. Students are also highly encouraged to opt-in to using the Gradescope platform to receive instant notficiation of assignment results via email and the web.

Active/Inactive Students

By default all students are considered Active in the course. However, students that meet any of the following criteria may be designated as Inactive:

  • Accumulating two unexcused absences within three weeks of each other.
  • Failing a Readiness Quiz.
  • Receiving excessive negative feedback on a Peer Evaluation Survey (or neglecting to complete it).

Such students may be returned to Active status by making an appointment and meeting with the instructor and signing a contract to address the issues that caused them to fall Inactive. A student that becomes Inactive three times will remain Inactive permanently for the semester.

Teams

Teams will be organized near the beginning of the semester. Much of our class meetings will be spent in teams completing activities related to the material, allowing students to master the course standards in an environment where they may discuss topics and ask questions freely with their peers and the instructor.

If any student from the class submits a request to the instructor by email to do so, a Peer Evaluation Survey will be conducted to allow teammates to provide anonymous feedback to each other.

Attendance

Attendance will be taken daily. Generally, only absences that have been previously approved by the instructor or that are related to a medical issue (with accompanying documentation from a medical professional) will be considered excused. All excused absences must be documented via email with the instructor.

Readiness Assurance

Before each module of the course, students are given a list of materials for review. Readiness for that module will be assessed on a Readiness Quiz, first individually and then as a team. High scores reflect sufficient preparedness for the module, while low scores demonstrate a need for further review. A 70% average of both quizzes is required to pass this quiz.

Class Activities

The instructor will introduce each course Standard, providing theory, formulas, and examples. After this introduction, students will collaborate on one or more team activities similar to exercises that will be assigned for that standard. These should be completed by each team on the provided whiteboard, showing all details and uploaded to Google Drive.

Mastery Quizzes

During most class days, Active students will be able to complete a short Mastery Quiz. Each non-modeling standard covered in class will appear on up to three Mastery Quizzes, at most once a week. A schedule of which standards are covered on each quiz is available on the Calendar.

Submissions by Inactive students will not be marked unless they have previously scheduled a time to meet with the instructor to discuss their status.

In addition, all students will be offered two 75-minute Comprehensive Mastery Quizzes and a 120-minute Final Exam that include exercises for every standard covered in the class to that date.

Quizzes are randomized and personalized for each student based upon their current progress; standards that have already been completely mastered by a student will not be assigned on the personalized quiz.

Marking Quizzes

Each submitted solution will be marked as follows:

  • Mastery Mark ✓: The solution demonstrates complete mastery of the given standard.
  • Revision Mark ✱: The solution might demonstrate mastery of the given standard, but needs to be revised for clarity/accuracy.
  • Issues Mark ⓘ: The solution demonstrates partial understanding of the given standard, but has one or more issues that suggest that further study is required to develop complete mastery.
  • ✘: The solution demonstrates negligible understanding of the given standard.

Only ✓ affect a student’s letter grade for the course; all other accumulated marks will be ignored at the end of the semester. So, a student who earns 35 ✓ and 3 ✘ throughout the semester will earn the same grade as a student who earns 35 ✓ and 300 ✘.

Revising Solutions

A student may improve a solution marked as ✱ to ✓ by completing a Revision Form outside of class and promptly submitting it in class, usually the following Tuesday.

This submission will be marked as usual, with at most one additional re-revision allowed in the case of a very minor mistake.

Modeling Projects

As they are covered in class, individualized take-home projects will be assigned based upon the modeling standards. These will be marked similarly to quizzes, except that all submissions may be revised for an improved mark.

Keep in mind that while the first submission will be marked promptly by the instructor upon its due date, further revisions will be marked based on the instructor’s availability. Since projects with even minor errors will be marked as ✱ and will require corrections, it’s highly encouraged that students write in pencil or type up their projects so they can be easily revised.

Project revisions are due either on the last day of class or the date of the final exam (depending on when the project was assigned).

Office Reassessments

During office hours each week, Active students may take advantage of Office Reassessments. Students that satisfactorily meet the requirements given on the linked form will be given the opportunity to solve a new exercise for credit.

Note that availability for this opportunity may be limited due to student demand, particularly later in the semester.

Missed Quizzes

Students that miss one or more quizzes due to excused absences may request additional time on the second Comprehensive Mastery Quiz held near the end of the semester.

Final Exam

The Final Exam is the same format as a Comprehensive Mastery Quiz, except that students will have 120 minutes and no revisions will be allowed. Instead, up to four ✱ marks earned on the Final Exam will be automatically upgraded to ✓.

In particular, demonstrating mastery on the Final Exam has the same benefit as demonstrating mastery on Mastery Quizzes throughout the semester, so students who keep up with the material throughout the semester will have a shorter final than students who attempt to cram everything in at the last minute.

Academic Honesty

Academic Honesty is defined in USA’s Student Academic Conduct Policy. Any student who is caught cheating will immediately lose credit for all earned ✓ throughout the entire semester, will become permanently Inactive in the course, and will have to take the remaining assessments by appointment in the instructor’s office. In addition, the incident will be reported to the university.

Any student who is caught cheating twice will automatically receive an F letter grade for the course.
