General Information
This is a short “conceptual” physics course for students who are either entering or are currently in
the Diagnostic Medical Ultrasound (DMS) program. The course is designed to introduce you to
various concepts in physics that are required by the National Education Committee for Sonography
(NEC) using as little math as possible. Specific topics are listed below.
NOTE: This course is only for prospective or current students in the DMS program. You will not
get credit for this course if you are in any other program, and the course will not transfer.
What Do I Need to Do Every Week?
(1) Go through the e-text Reading
Each week (after the first week), there’s specific sections in the e-text (contained in the
MasteringPhysics program) that you need to read. Each week’s reading assignment is listed below.
The e-text also contains some videos and interactive modules that will probably help as you go
through that week’s homework and quiz.
(2) Check Out and Print the “Notes and Equations” PDF File for the Week
Each week (after the first week), I’ve posted a “Notes and Equations” document that covers all the
specific stuff out of the week's material that you need to know for that week's homework and quiz.
You should print this out and have it with you when you do the homework and quizzes.
(3) Do The Homework
Each week (after the first week) there’s a homework assignment in the MasteringPhysics program
you need to go through. You can take as many shots as you need at each question, but you need to
answer them correctly in order to get full credit. The homework is worth 40% of your total grade for
the course.
Post to the weekly forum or email me at demarcochrisj@jccmi.edu if you have trouble with the
homework!
(4) Do Forum Postings
Each week (after the first week) you’re required to post at least twice to the weekly forum, either to
post something you thought was interesting, ask a question or answer someone else's question. You
need to post at least twice in order to get full credit. The forum posts are worth 10% of your total
grade for the course.
(5) Take the Quiz
Finally, each week (after the first week) you’re required to take a quiz over that week’s material.
You can only take the weekly quiz between 8am and midnight of the Friday of each week. Here,
you only get one shot at a question. Again, print out the weekly "Notes and Equations" thing to use
as a guide as you take the quiz. The quizzes are worth 50% of your total grade for the course.
NOTE: The last week of class ends on Thursday, 12/22. That last week, you can take the quiz
anytime between 8am on Monday, 12/19 until midnight on Thursday, 12/22. That way, you can
finish early if you want to.
Grading
e-Text Readings and Homework: Each week, you need to read the assigned sections from the etext, which is available in the MasteringPhysics program, and do a homework assignment which is
also contained in the MasteringPhysics program.
You get credit for the homework as long as you complete it. You won’t get penalized for putting in
wrong answers, so you can put in as many answers as you want. But, for each question, you need to
eventually put in the right answer to get credit. The homework must be completed by midnight on
Friday of each week.
All of the homework assignments together are worth 40% of your grade.
Forum Posts: Each week (except for the first week), you need to get onto the weekly forum in
JetNet, post at least twice with questions relevant to the material and/or try to answer someone
else’s question.
You’ll receive full credit for doing both posts if it looks like you made a serious attempt to do them.
You’ll get half credit for doing just one post, and, obviously, no credit for doing neither of them.
The forum posts must be completed by midnight on Friday of each week.
All of the forum posts together are worth 10% of your grade.
Quizzes: Each Friday (except for the first week) you need to take a quiz of roughly 30 multiplechoice questions over the material covered in the e-text and the homework during that week. The
quizzes are also in the MasteringPhysics program.
The quizzes can only be taken between 8am and midnight on that Friday, and you have to complete
them within 90 minutes.
These quizzes are the only part of the course which you don’t get credit just for doing them. You
only get credit for a quiz question if you get the correct answer, and you only get one try at
answering a quiz question.
NOTE: Once you submit the answer to a quiz question, you can’t go back and change it. You can,
however, skip a question and go back to it later. Make sure you make a note of questions you skip
so you remember to go back and answer it!
Each quiz is graded on the basis of your percentage of correct answers, and all of the quizzes
together are worth 50% of your grade.
Grading Scale:
Your overall grade will be determined using the following scale:
90% – 4.0
85% – 3.5
80% – 3.0
70% – 2.0
65% – 1.5
60% – 1.0
75% – 2.5
55% – 0.5
Late Policy
Homework and Forum Posts: There is no opportunity to make up these assignments if you miss
the weekly due date. You can work ahead on them, though, if you need to.
Quizzes: You have to take the quizzes each Friday (except for the first week) between 8am and
midnight. You will be able to make up a quiz only if you inform me that you will be unable to take
the quiz during that time before the quiz is given, and then only under unusual circumstances.
