Course Description: Math 130 is a flipped course with online section notes, videos, tutorials, assignments, and tests.
Math 130 is designed primarily for students who will enter the calculus sequence Math 231-233. Topics include the
basic concepts of trigonometry and analytic geometry and algebraic concepts relevant to the future study of calculus.
The course is mainly problem oriented, and you should anticipate spending about 12 hours per week on this course. (3
credits)
Emails: Course emails will be sent via CC and will include important items of business.
Section Notes: Links to section notes, that accompany the material in the text, are available on WA. The notes include
section objectives, required readings, a discussion section with additional worked examples, helpful hints, warnings
about pitfalls, and a list of practice problems from the text.
Section Videos: Links to videos are available on WA. These short videos introduce topics or demonstrate how to solve
various types of examples.
Assignments:
 General WA Assignment Information
o All WA assignments are open resource and not proctored.
o Due dates for each assignment are listed on your Schedule of Instruction and on WA.
o You will have 1-3 attempts to answer each question correctly.
 1 attempt for binary type questions such as true/false or multiple choice items with 4 choices,
 2 attempts for multiple choice items with 5 choices,
 3 attempts for open response questions that are not binary in nature.
o After an assignment is past due, to view the assignment and/or key, click on Past or All Assignments,
click on View Key.
 Before-Class WA assignments
o Vocabulary, Review, or Tutorial style questions
o 22 assignments, each worth 5 points, due 1 hour before the start of class

 If you added this course after the first day of classes, you are responsible for contacting the course coordinator
immediately to arrange to make up all missed assignments.
Class Time: The 50-minute meeting will either be a Problem Session day or a Help Session/Review day as indicated on
your Schedule of Instruction.
 Problem Sessions will involve working problems on the During-Class WA assignments. Prior to each Problem
Session, read and study the appropriate section notes and section from your text, watch the video(s), and
complete the Before-Class WA assignment. Bring your computer, textbook, and calculator to the meeting and be
ready to work.
 Help Sessions are a time to get help from your instructor on concepts or WA assignment questions in a smallgroup or individual setting. Bring your computer, calculator, and textbook. These sessions are mandatory if your
HW assignments are not complete at 80% or higher.

You will take 3 computer-generated tests on your laptop computer with only 1 submission each.
Test deadlines are listed on the Schedule of Instruction along with the sections covered on each test.
All tests are proctored, calculators are not allowed, and test scores are not curved.
You will need to show all work and your answer clearly marked on the cover sheet and pledge.
Be sure your computer is charged and that your wireless access works in Phillips 335. Power and Ethernet cables
are recommended. Each student is responsible for his/her working, connected computer.
At the end of the semester, you may elect to retake 1 of the 3 tests. The higher score will be the one that counts.
See the Schedule of Instruction for the Retake test date.
There are no extensions or make-up tests. If a test is missed, it will be scored as a zero no matter what the
excuse. The retake can be used to replace the zero.
Shortly after a test deadline, the scores and answer key will be released on WA.
After a test is released, to view the test and key, click on Past or All Assignments. Click on the test you wish to
view and click on the View Key box.
Final Exam: The comprehensive, paper-and-pencil final exam will be taken on Thursday, April 30 from 4-7 PM. This
is a common exam taken by all sections of Math 130 at the same time. Old final exams and keys are on WA. A
certain level of performance on the final examination will be required to earn a grade of C- or higher in the course.
Grading System:

Entering Answers on WA:
 Know the difference between tenths vs. tens, etc.
 Know the decimal location of tenths, hundredths, etc.

 Enter a calculator value when asked to round to the nearest …
otherwise provide the EXACT answer such as
2 or

.
3

Use lower case pi   , not upper case    , or you can simply type pi.

Use parentheses around arguments of functions, i.e. sin (2x) not sin2x or ln  2x  not ln 2x .
 Use the right arrow key to exit a function.

Success in Math 130
Emails: Read all course emails! They include important business items.
Study Suggestions: Some Guidelines to help with success in this course.
 First reference the Objectives and the Required Reading portions in the Section Notes for the section you are
about to begin.
 Carefully read the corresponding section of the text and the Discussion portion in the section notes.
o Be an active learner; keep paper and pencil handy while reading and follow along with each example.
o Try to avoid using your calculator unless a question says, “answer to the nearest …”.
o Watch the videos for the section.
o Complete the Before Class WA assignment.
 Start the WA assignments within 24 hours after each Problem Session and treat each attempt like it is your only
attempt; do not just guess. Have your Section Notes available and your textbook open so that you can match
each WA question with the question from the text and see the groupings of questions with common directions.
 Be sure to work the Not-On-WA Problems from the Practice Problems List.
 Be a good problem solver. Draw pictures when applicable.
 If you are having difficulty with a WA question, reference your section notes, textbook, videos.
 Seek help when you do not understand a concept.
 Be sure that you understand and can work all problem types from the Section Notes, Videos, and WA
assignments without any assistance.
 You can rework problems from the assignments on WA using Practice Another Version after the due date.
 Always remember that it is important to Communicate Mathematically when working problems or writing for a
test or the final exam. Write in a mathematical fashion using numbers, variables, symbols, and words to clearly
express your solution to a problem. A solution to a problem includes not only the answer(s) clearly indicted, but
also the logical progression of steps to achieve the answer(s). When applicable, clearly label all sketches, graphs,
and/or charts.
 View all assignment/test keys. Carefully review all graded materials and rework problems that were not
completed correctly as soon as the key is available. This will help you avoid making similar errors in the future.
General Suggestions:
 Avoid having more than 2 back-to-back classes.
 ARS students with extended time on tests must be free either before class or after class.
