Email Etiquette

Effective communication is crucial for a successful online learning experience. Please adhere to the following guidelines when corresponding via email:

For Your Instructor (Me)

  • Response Time: Please allow me 24-48 hours to respond to your emails. During weekdays, I usually respond much faster.

  • Check First: Before emailing, always check the Syllabus to see if your question has already been answered there. This helps ensure a quicker resolution for common inquiries!

For You (The Student)

  • Official Email: Always use your CLC email to correspond with me.

  • Subject Line Clarity: Your subject line must include the name of the class you are in (e.g. of subject lines, "MTH 144 Homework Question" or "Precalc - Help"). I teach multiple online classes, and including this information will help me respond to you much faster without having to look up which class you're in.

  • Clear and Complete Questions: Use complete sentences and be as clear and specific as possible when asking your questions.

  • Visual Aid: If you are encountering an error or a technical issue, please include a screenshot to help me understand and address the problem more effectively.

Late Work

Extensions will be granted on a case-by-case basis and is situation dependent. I understand that things come up, and communication is essential. Emailing me to communicate your situation (if possible before the missed class/assignment) is your responsibility, but not a guarantee of an extension. (csizemore@clcillinois.edu). There is no make-up for exams. The final exam will replace a lowest exam grade (if higher). While this policy provides a safety net for an off day or unexpected circumstances, you should plan to take all three exams. Missing an exam intentionally removes your buffer against illness, emergencies, or underperformance on a later test. Be strategic - take every exam and give yourself the best chance at success in the course.

AI Usage Policy

I'm okay with you using artificial intelligence (AI) as a tool to help you succeed in this course. While AI can be a powerful learning aid, it's important to use it wisely and responsibly.

Acceptable Uses of AI

Feel free to use AI to:

  • Check your work: Use it to confirm your answers for homework problems.

  • Debug your errors: If you're stuck, ask the AI to identify and explain where you've made a mistake.

  • Get targeted help: Share a specific part of a problem you're struggling with and ask for guidance.

  • Deepen understanding: Have the AI explain a challenging concept in a way that relates to your hobbies or interests, or ask it to show you how to use your calculator for a specific task.

Unacceptable Uses of AI

Using AI for any of the following is considered academic misconduct and will not be tolerated:

  • Completing exams: All exams are proctored in person so will not be allowed to use AI. Exams make up 80% of your final grade.

  • Submitting AI-generated work as your own: The goal is for you to learn the material, not for an AI to do the work for you. Using AI to generate a complete solution that you then submit is prohibited.

  • Being caught submitting work that is AI-generated or trying to use AI during exams twice may result in a failing grade for the course.

Grading

Your overall course grade will be based on your performance on the WebAssign Homeworks, Exams, Cumulative Final Exam and Check-in Assignments.

Exams (proctored in person)

You will have three exams and a mandatory cumulative final exam. You may not use books, notes, unauthorized calculators, phones, tablets, AI or software applications during the exams.

Exam Requirements: All exams are taken in person at an approved testing center. You cannot just drop in. You will have to schedule an appointment at least 12 hours in advance. Spots at the centers fill quickly.

Exam dates are fixed and listed in the course schedule below. Mark these dates on your calendar now and plan accordingly - request time off work, arrange transportation, and avoid scheduling other commitments on these days. If you anticipate any conflicts, contact me immediately rather than waiting until exam day.

Exam Dates

Exam 1Friday Oct 2nd - Wed Oct 7th
Exam 2Friday Nov 6th - Wed Nov 11th
Exam 3Monday Nov 30th - Friday Dec 4th

Final Exam

The Final Exam is a cumulative final that covers all the material. The final is set up like the unit exams but covers more material. Final must be taken to receive a passing grade (A, B, C, or D).

Final Exam is Wed Dec 9th - Thursday Dec 10th

WebAssign Online Homework 

Online homework will be assigned after each class session and is due on Mondays. 

Regular practice through homework is essential for mastering mathematical concepts - problems are carefully selected to reinforce your understanding and build computational fluency. If you find yourself struggling with the material, please utilize office hours, the math tutoring center, or email me to get help early rather than falling behind.

Check-in Assignments: 

Additional assignments like discussions, Kahoots, reflections, and engaging activities are scheduled weekly throughout the semester to enhance your learning experience. Don't worry – each one will come with clear instructions and plenty of notice about due dates, and together they'll account for 5% of your final grade. These assignments are due on Wednesdays. To address extenuating circumstances, one check-in  assignment grade will be dropped.

Withdrawing from Class

You are responsible for dropping or withdrawing from classes you do not intend to complete. Grades of W will only be assigned to students who withdraw themselves. Tuition and fee refunds will be issued to eligible students based upon the effective date of withdrawal, which is recorded in the system at the time the student drops the class.

Instructors are required to administratively withdraw students who never attended or stopped attending class. All administratively withdrawn courses will remain on your academic record and are not eligible for a refund. Grades will be assigned based on dates of attendance:

WN – You never attended class: no impact on GPA

WS – You stopped attending class: no impact on GPA

FW – You stopped attending class after the official withdraw deadline and your instructor deems you failing: equivalent of F grade for GPA.

In order to withdraw and receive a grade of W after the deadline, you must request a withdrawal from your instructor; requests must be made in writing and additional approvals may be required. You must have a passing grade at the time the withdrawal request is made. Once approved, you will be withdrawn from class.

Withdrawing from the Class: There are 3 types of Withdrawals

Withdrawing from a class means that you no longer want to be enrolled in the class. Your transcript and the grade for the course may vary depending on the time at which you withdraw or request to withdraw from a course. The table below briefly outlines the actions you must take and the potential outcomes if you decide to withdraw from this course. I can help with understanding the difference. We can discuss different options if you are unsure.

If you wish to withdraw:
