Modules:

Study the linked on-line material before the end of the day in the reading scheduled.  Make sure that you can work the problems that are worked out in the web material.  Explore some of the links that are embedded in the web material.  Read the associated chapter in the textbook.  Complete homework assignments, laboratories, and extra credit assignments and contribute to the module discussion before midnight on the due date in the homework, lab, and extra credit schedule.   

Homework assignments:

• Assignments cover the material presented in the online material.  They may refer you back to a module or to some activity you were asked to complete in a laboratory.
• Assignments are submitted online on Canvas.  Assignments are scored by the computer and you will receive your assignment grade immediately.  You can submit the assignments up to three times if you need to improve your score.  The highest score counts.
• Assignments are due at 11:59 PM on the indicated date.  No late assignments will be accepted.

Laboratories:

Each section has its own lab instructors.  The lab instructor will help students with the laboratories and grade the lab reports.  The Spring 2026 Physics 221 Lab Syllabus on Canvas explains the lab grading policy.  You cannot earn passing grade for the course, unless you earn a passing grade for the labs.

Class participation:

Participate in online discussions for class participation credit.  Meaningful participation before the due date of the second homework, lab, and extra credit associated with a module gives you 100% class participation credit for this module.  Post questions, answers, hints, comments, etc, under one of the suggested topics or start your own topic.

What is a meaningful contribution?

Extra credit assignments:

You can earn up to 50 extra credit points from answering extra credit questions on Canvas.  You can submit the Canvas extra credit assignments up to three times if you need to improve your score.  The highest score counts.  The questions are challenging, but you are encouraged to discuss extra credit questions with your fellow students before the submission.  Extra credit points are added to your total score from tests, homework assignments and laboratories. 

Tests:

Tests are 90-minute online exams.  Test 1 questions are about material covered in modules 1 - 6, and test 2 questions are about material covered in modules 7 - 12.  You will take the tests online using the Chrome browser with the Proctorio extension during any 90-minute period between 7:00 am and 11:30 pm on the test day.
