**Special Course Notes for PHYS 150**

Note on regular homework: You must
use the 7 step problem solving paradigm:

1. State this at top: I want to and I can

2. **Draw
a diagram** and include what you know on the diagram

3. Show on the diagram what you are looking
for

4. State basic laws or relations that
apply to the situation (e.g.,
Conservation of Energy, Newton’s 2^{nd} Law)

5. Write equations named above that
relate what you know to what you are looking for.

6. Show your work and include units
whenever you use a numerical value.

7. See if your result is reasonable.

Note on homework. The homework is not just graded on whether you can get the correct answer. It is also graded on how well you can communicate your process using the 7 steps above.

**Opportunity to improve one test grade:** You can get up to half credit
for the questions you missed on any one of the first three tests if you do the
following:

a) for questions you got correct, nothing is required;

b) for yes/no or less than/greater than type questions, please tell me the
correct answer and, if possible, why you answered the way you did;

c) if you just missed units, then simply correct the units;

d) for regular numerical answers, write up the solution in the **regular homework seven step paradigm**
method.

Doing the above can earn you up to 50% credit on the points you missed, so if you made a 50, you can raise your grade up to a 75; if you made a 75 you can raise it to an 88; if you made an 88, you can raise it to a 94; etc.

**You must turn in your original test with your corrections ** so I know how much to award for each part.

Please note that this **applies only to
one** of the first three tests. You can wait until after the 3^{rd}
test to choose which test you wish to correct in this manner. You must turn in
your corrections in the above format by the last regular class of the term.

If you have three or fewer absences, I will still drop your lowest test.
