Old Announcements
- If
you have any questions regarding the grading or about upcoming
homework or anything else you are encouraged to ask before or after
class or in office hours.
- Grades
in the left margin mean: check-plus=perfect or nearly perfect, check=mostly
right, check-minus=mostly wrong, x=nothing or nearly nothing.
The
initial marks and scores were fairly lenient as you get used to what is
expected. As we go along expect them to become more stringent!
- On homework please
- start all problems at the left margin,
- write your work as clearly as possible including using pencil (or white out errors if using pen),
- give complete answers including explanations and responses to all parts of the problem,
- use
graph paper for all graphs and label scales, variables, and (in applied
problems) meanings and units for those variables on the axes,
- round
to the number of decimal places listed when requested in the problem
(and show this using an approximation sign rather than an equal sign),
- use correct notation including only connecting items by an equal sign when they are really equal.
- The updated class directory and solutions to selected problems from homework, quizzes, and worksheets are posted in Moodle.
- The Math
Center is now open for drop-in tutoring help in Museum 433 M-Th 9am-7pm
and F 9am-2pm and in CHE 220 in Idaho Falls M,W 9am-3pm, T 9-9:30am,
10am-4pm, Th 9-9:30am, 10am-3pm, F 10am-1pm.
- Some
studying suggestions for the exam: start early, work extra problems from
the book including the review at the end of the chapter (it is
especially important to work different types of problems mixed
together, as opposed to ordered by section, and to work problems
without your book or notes available and under some time
pressure), go over old homework and quizzes, reread sections and
use supplementary materials to make your own outlines of important
points, check if you can do the objectives below, come and ask
questions in office hours.
- Exam 1 revised: Mean: 73.2 Median: 72.5 High: 95.6
Your
slip shows all the scores I have recorded for you - please check these
and bring any errors to my attention. It estimates your grade in
the course by dropping the lowest quiz and the lowest homework scores
and weighting your exam score as 76% of your grade. Later exams
will give you the opportunity to change this. - Remember
that in-class work (worksheets and other problems covered in class and
turned in for points based on effort) counts as 8% of your grade.
- For
the Mastery Quiz you
should be able to work straightforward differentiaion problems
involving the constant mutliple, sum, difference, product, quotient,
and chain rules applied to all basic types of functions (powers,
polynomials, exponentials, logarithms, trig functions, inverse trig
functions, hyperbolic functions, and inverse hyperbolic functions).
If you do not get at least 7 of the 8 problems perfect then you
will need to take a new version of the quiz outside of class time until
you do so. A good way to study for the quiz is to work as many of
the 50 differentiation problems in the Chapter 3 review as possible.
- Make sure to always include units in answers to applied problems - consider the NASA Mars Lander example!
- Midterm
grades were submitted for those estimated to be earning
below a C- in the course - please check your MyISU. If you
received one of these you are especially encouraged to come ask me
questions individually to help improve your grade as I believe all of
you are capable of succeeding in the course given sufficient and
consistent hard work.
- You may submit a problem you make up (not just taken
from the book), that is at a medium level of difficulty and testing one
of the objectives listed for one of the sections on the exam. You
will earn up to 2 points toward your in-class score and your problem
may be chosen to be on the exam depending on the appropriateness and
creativity of the question.
