Why Am I Here? Top
Reasons
 I have a natural love for the subject
 I heard a really good instructor was teaching the
course
 I like skipping my meal to feast on intellectual
stimulation
 I love the punishment and pressure (I also slam my
hand in the car door for fun)
 My department requires this course and I want to get
out of here and make some money
 The class is about money and how to get more of it –
Whats not to like?
Why Your Department
Requires it
 Your degree teaches you how to design things
 Building them costs money
 People Build Things Because They Make
Money
 The difference between a paper decoration
and a project may come down to whether you
can show it will make money
Another Reason
 Taking Care of #1
 Personal Investments involve making money
 Credit cards, loans and mortgages all require
paying extra money
 Choosing ways of meeting needs have both
extra costs and cost savings
 Understanding how money and interest works
helps you to keep more of the green for
yourself
How will I be Graded?
 Grading will be based on points earned
 Points come from Homework (about 23
problems) and Two Tests
 Each Test will be 25% of the grade (50%
total for tests)
 Homeworks will be equally weighted and
the average score will be 50% of the
grade
What Will You Do With the
Points?
 Grading will be on a strictly % basis





90% + = A
80% + = B
70% + = C
60% + = D
<60% - You'll get to enjoy my course again
in the fall
What Kind of Tests Do You
Give?
 Tests are open book open notes
 If you can hook to internet you can use that
 If you want to bring a computer or financial calculator you can
use that
 You cannot use another person in any form
 Usually about 2 problems
 Often similar to homework (another reason to do your
homework)
 May have multiple problems with you picking what to do
 Don’t give you a do them all and take grade on best
 Old Test Archives on the Web lets you look at previous
tests
 I also have often posted practice tests.
More on Tests
 In general tests are time intensive
 If don’t already have an idea what the
answer is
 If your trying to do research during the test
 Your probably a sunk monkey
Homework
 Homework is intended as an application
exercise for class
 Get your hands on the problem or procedure
 Working in groups is acceptable
 Sometimes learning from your peers or being the
teacher for a while is best way to learn
 Everyone must turn in an individual assignment
 Just copying the work of others is not
acceptable
Homework Timing
 Most homework can be done in 20 minutes or
less
 If it is taking you more you have probably become
lost (might be good to consult a friend or the
instructor)
 Warning on Wait till 30 minutes before class
approach
 Often are best able to do homework right after
learning about how – not waiting several days
 If something goes wrong you won’t make it
Textbook
 Don’t require a textbook
 Makes class attendance more critical
 Some People Learn Best from Reading or Alternate
Perspectives

(2nd Addition)
Two books are same for chapters covered
 Portions of these books are available on-line
Comments on Learning
Resources
 Resources Available
 Class Lectures (attending class)
 Doing Problems
 Class Website
Class Attendance
 In general this is #1 correlation with A students
 Professors are most likely to test what they teach
 If its on their mind when their lecturing its likely to be on their
mind when they test
 My class is designed to emphasize lecture heavily
 Material found only in the text book isn’t going to be on the test
 My approach to subject differs from the book
 Uses a lot of examples to illustrate
 Uses a lot of intuitive logic as opposed to proofs and derivations
Doing Problems
 Given a series of assigned problems
 Most assignments are a single problem
 Purpose is to give you hands on experience
practicing something covered in lecture
 An issue of Balance
 Tried to keep modest reasonable workload for 2
credit class
 Problem
 Some people learn by repeatedly doing
 Not enough homework problems to beat it into
your skull
 Can do supplemental problems from book
Class Website
 Web site has copies of all lecture notes
posted
 Some print out and take notes beside
 Warning – some feel easy access to notes
removes need to attend class
 Not enough text on power point slides to teach
everything
