6. Course Format:
This class will require active engagement from you, because that’s truly how we learn best. This is a flipped
class, which means that in-class time will be primarily spent on what was traditionally called “homework” (in
this case, solving statics problems). The course format looks like this:
a. Before each class: Watch the assigned videos, read the assigned sections from the textbook,
and complete the MasteringEngineering Homework assignment for the corresponding sections.
Take notes in your notebook. If you have questions about assignments that are due at the
beginning of the next class, contact your classmates or me ahead of time.
b. In class: Turn in notes as requested. Ask any questions that have come up when preparing for
class and completing assigned problems. Work on the EOS problems for the current sections,
and ask questions as they come up. Some days there will be a quiz.
c. After each class: Finish the assigned EOS problems from the previous class and submit the
answers via MasteringEngineering. If you have questions, contact your classmates or me before
the assignments are due.
d. Then repeat the cycle
7. Grades:
Your grade for the course will come from the following categories:
MasteringEngineering Problems (20%): You will work on MasteringEngineering problems both
outside of and during class. This is the primary way you’ll practice working out solutions to
problems. The MasteringEngineering assignments will be submitted online and counted toward
your homework grade.
Note Checks, Quizzes, and other in-class assignments (20%): I will check your notes for a randomly
selected video or ME problem at the start of each class period, and you will be given up to 2 points
for thoroughly completing them. Quizzes will be given most weeks throughout the semester and
may or may not be announced. You are expected to come prepared to each class meeting. There
will occasionally be other activities or assignments in class to supplement your learning. The lowest
quiz score and lowest two notebook scores from the semester will be dropped.
Tests (30%): There will be three tests given during the semester, as shown in the schedule of topics.
Each test is worth 10% of your grade.
Final Exam (30%): The Final Examination will be comprehensive and worth 30% of the semester
Letter grades correspond to the Final % as follows: A = 90-100; B = 80-89; C = 70-79; D = 60-69; F = 0-59
8. Online Discussion/Communication: Canvas
Rather than emailing questions to me, I ask that you post your questions in the Canvas Q&A/Discussion
forum so that your classmates can benefit from the question and ensuing discussion and answer. I
encourage all of you to respond to each other’s questions – this way you may get an answer much faster,
and you can just as easily learn from each other.

Statics – ENG GEN 131
Fall 2016
Tips & Guidelines for posting in Canvas:
 In the topic name, state the specific problem, assignment, and/or section number (as applicable) that
you are asking about.
Before posting, check that someone hasn’t already posted about a similar topic. If so, see if you can find
your answer there, and post within the same thread if you need to ask something additional but related.
Be detailed - the more detailed you are when asking your questions, the more likely some is going to be
able to help you. Describe what you have tried and where you are stuck.
Please respond to other students when possible, and be respectful in your responses.
9. MasteringEngineering:
 You will use MasteringEngineering to access reading and video assignments, tutorials, and assigned endof-section problems.
MasteringEngineering assignments will be due on Tuesdays and Thursdays prior to the start of class. All
due dates will be given within MasteringEngineering.
Your MasteringEngineering assignments must be submitted on time in order to receive full credit. I still
encourage you to complete assignments, even if they will be late. Late assignments will be accepted
with a 1% deduction for each hour they are late.
The MasteringEngineering assignments are grouped into one of two categories:
Homework includes video lectures, tutorial-type problems, where you will be given hints along
the way; coaching activities, in which you will watch a video solution example prior to solving a
similar problem on your own. For the tutorial-type problems, I encourage you to use the hints
when needed. You will not be penalized for using the hints, nor will you receive bonus points if
you do not use them.
End-of-Section (EOS) problems are problems from your textbook, but may have different
numerical values.
Although MasteringEngineering only requires that you submit your answers, and not your work that led
to the answer, I’m going to require that you neatly complete the work by hand on paper, identifying
each problem. See the posted instructions for formatting problem solutions. This habit will be helpful
for several reasons:
On quizzes, tests, and exams you will be required to submit all work. In order to award you
credit, even if the answer is wrong, I’ll need to be able to follow what you’ve done. If you get in
the habit of working out your problems neatly, it won’t be hard for you to keep doing this when
taking the tests.
If the answer is wrong and you need to go back to see what mistake(s) you made, you’ll need to
be able to follow your work.
If you need to ask for help on solving the problem, you’ll need to be able to explain what you
10. Attendance and Make-ups:
Page 3 of 7
Statics – ENG GEN 131
Fall 2016
I will be keeping attendance through the last day to drop. Attending class is essential to your success
in learning. This is not an online class. The “flipped” model only works if you come to class prepared,
and are able to engage with me and each other. In addition to time spent solving statics problems,
class time may include quizzes and other important activities. Therefore, my drop/exclusion policy is
as follows:
4 unexcused absences (=2 weeks of class) and you will be excluded from the class.
However, if your intention is to drop the class, do not just stop attending and assume you’ll be
dropped. It is still your responsibility to drop the class.
Excused absences: If you will be absent due to religious holidays or other planned events, please let me
know the date(s) and reason in writing as soon as you are able to. If you miss class because of illness or
emergency, contact me as soon as you can. If you miss class for any reason, please be sure to obtain any
missed information from another student.
In-class activities (quizzes, notebook checks, other activities) may not be made up for any reason.
Make-up tests/final exam will not be given except under extraordinary situations (such as a severe
illness or an emergency) and when proof is provided that you were physically unable to take the exam.
If you need to request a makeup test/exam, please follow this procedure: Ask in writing as soon as
possible (email), and include an explanation for your request, and the earliest date you will be able to
take the test.
11. How to succeed in this class
Come to class prepared and on time, and be mentally present while engaging with course material.
Successfully learning statics (or anything else) requires active involvement on your part, both in class
and on your own. Outside of class, you should expect to spend approximately 10 hours per week
studying, with the majority of this time spent working out practice problems. While reading the text and
watching video lectures is important, you cannot adequately learn statics without lots of practice solving
Begin assignments early. Even if you know how to do all of the problems, they will take time to
complete. More than likely you’ll have some questions along the way, and starting early will give you
time to ask me or your classmates questions if you get stuck.
Ask for help when you need it. Don’t be shy – if you already knew it all you wouldn’t be taking this class.
The most successful students are those who ask for help when needed. There are several ways to ask
for help:
Ask in class: there will generally be lots of time to do this, as you’ll be watching the lectures
outside of class.
Come to see me during office hours.
Ask in the online (Canvas) discussion forum outside of class.
When studying for exams, go back and rework problems that have been assigned (in-class and through
Mastering) and solve new problems from your textbook. I will assign bonus problems in
MasteringEngineering for each chapter that serve both as extra practice as well as extra credit. It’s just
like physical exercise: the more problems you work, the better you’ll be at solving them on your own.
Page 4 of 7
Statics – ENG GEN 131
Fall 2016
Work collaboratively. I strongly encourage you to form study groups to work on practice problems. This
helps with keeping you motivated and keeps you from getting stuck on something for too long with no
one to ask.
Make sure you can solve problems successfully on your own! This is critical. Although working in groups
is great, you do need to be able to solve problems without help too. I am aware that solutions manuals
are available, however, copying from them will not help you learn. It’s obvious when students do this –
the result is great homework grades and terrible quiz and test grades.
Before submitting an answer, be sure your answer makes sense. Ask yourself, “Does it have the right
units? Is it physically reasonable?”
12. Collaboration vs. Cheating:
I encourage students to work together to understand concepts and tackle assignments. This is
collaboration, when each student still submits his/her original work. Cheating is a different thing entirely
and involves submitting work that has been copied for an assignment, quiz, or test. Examples of cheating
include copying work from another student or any other source, allowing someone else to assume your
identity for submitting assignments online, using references not allowed by the instructor during a quiz or
exam, or copying text from any other source without proper citation (see www.plagiarism.org). If you are
caught cheating, all students involved will receive a zero on the assignment(s), quiz, or test, a report may
be submitted to the Dean of Student Services, and more serious consequences may result.
The purpose of the assignments given in this course are to give you practice applying the concepts you’re
learning, and are therefore part of the learning process. Cheating directly threatens the goal of learning. If
you don’t understand how to do something, ask for further help so that you understand to the point where
you can complete the assignment yourself. Students who have been copying work never do well on tests
because they haven’t learned the concepts.
13. Mobile Devices:
Because of the flipped model of the class, I will allow you to use a mobile device in class exclusively for the
use of completing class related work. You will not be permitted to use mobile devices for any other purpose,
as this is a distraction both to you and everyone else in the room. If you are using your device for an
unrelated purpose, I will count you as absent for that day. The use of mobile devices is prohibited on
quizzes or exams.
Note: It is not a requirement that you have a mobile device in class, but it will assist by allowing you to
access MasteringEngineering.
14. Email Communication Guidelines:
 Please only use my email to send me private messages that are not related to course content.
Otherwise, use the Canvas discussion forum.
Written communication is an extremely important skill, even for engineers. Please keep all email
messages to me professional by following these guidelines:
o Include a brief subject related to the reason for your email.
o Include a greeting (Ex. Dear Professor Cheung,).
o Use complete sentences.
o Spell check – almost all email systems can do this.
