Grades are loaded on OWL and SPIRE.

There were alot of good grades!  I went as low as 68.5% to give “C”, in order to be sure than anybody on that C/C- boundary got the benefit of the doubt.

Points came from:

1) exams + blog (70% of points): 420 points (100 per MT, 120 for final; up to 5 extra points added for blog participation).

The lowest MT was replaced by a better final (on a percentage basis!) as shown by the extra column of numbers in the OWL Gradebook.

2) Lab (17% of points) 100 points

3) OWL (10% of points) 60 points.

4) PRS (3% of points) 20 points.

*******************************

Letter grades have been placed on SPIRE

Letter grade regions will be pretty close to traditional percentages, but this is key:  you need a passinge exam average to pass the class. I accepted an exam average as passing if it were greater than 54%.

Yes.  Probably.

The final exam is worth 120 points.  Each MT is only worth 100 points.  Therefore, the replacement of a low MT by a Final is on a percentage basis.

For example, your lowest MT = 55, your final = 90.  You do not get a 90 for that low MT.  Instead, you get (100*90/120 = 75).  So a “75” replaces the “55”.  Please double check your calculation of percentages – before you write to ask about this!

Merry Christmas!

ChemPrep is an optional preparatory OWL course for students prior to starting GenChem.

http://www.chem.umass.edu/chemprep/chemprep.htm

It is optional, and provided as a way for you to be better prepared for the course.  You are still eligible for GenChem, even if you did not chose to take advantage of this opportunity.  ChemPrep does not directly figure into your course grade in Chem 111.

This is the website for Chem111 (sections 3,4).  Feel free to look around and post comments.  I look forward to meeting you in the Fall.

Lecture begins on Wed., Sept. 9
You will need to use your PRS transmitter during each class.

Labs begin on Sept 14 (or after, depending on  section).
