As each term completes, the Cumulative Total for the Year will update. Included
in this WebScores summary view is the total number of points earned by term,
the percentage score by term, the grade earned by term, and a projection for
the year-end course grade based on the term percentage grade to date. Note that
when all is complete, each term will count 20% toward a total of 80% for term
scores, and the final exam will contribute the remaining 20% of the total from
which the course grade will be calculated.
Scores are recorded in four major categories, plus
possible bonus points:
At this time you should plan on two tests per term. Tests are usually
100 points, and will be written to take 40 minutes, although 55 minutes will
be allotted. Sometimes a test will be a unit test that is given at the completion
of a chapter of the book. As your background in chemistry builds and our pace
increases, it is more likely that a test will cover more than one chapter.
The focus material for each test will be made clear in advance of the test.
Note that chemistry is inherently cumulative, thus necessarily material studied
from previous units will appear in current tests.
Quizzes are designed to take 10 minutes, and are generally 20 or
25 points; quizzes will be given as needed. Quizzes will usually be announced
several days in advance, however, this is not a promise. The focus on quizzes
can be over a portion of a chapter, or over the entire chapter as preparation
for an upcoming test.
Homework is a catch-all term for assignments given. Certainly this
category includes all assigned chapter homework and worksheets that are intended
for completion outside of class time. Also included in this category are your
chapter summaries in you reading notebooks, and in-class group work and other
Laboratory assignments are all forms of written material pertaining to laboratory
work, plus any points given for safety inspections and workspace clean-up.
Written assignments include. pre- and post- laboratory assignments, laboratory
data sheets and prepared report forms, and written scientific laboratory reports.
- Bonus Points
Bonus points may be made available as difficult problems on quizzes and tests,
but also as special assignments given in class. Or, bonus points may not be
offered at all. We'll see.... Bonus points are added directly to your total
score, and will be used to calculate your term total percentage score. Bonus
points will, however, not show up in any other category total, even if offered
on a test or quiz.
- Lex, Hex, Gex or Qex
Anything with the ending ‘ex’ are points that have been excused for one or a few specific students. Why might a student be excused from assignments? Here are few examples: (1) A student transfers into a class mid-term, thus is excused for some or all of the earlier assignments. (2) A student is excused for medical reasons from certain assignments. Points that are excused for a student are subtracted from the denominator, thus allowing the precentage score to be calculated based on fewer total points. Most students should have no points under these labels.
Webscores identifies each item by a code. Use the links below to translate
the codes into short descriptions of the assignments that have been issued to
date for each term. You may also view a histogram of the percentile scores for
the entire class. Note that when the information displayed is for the current
term, the scores shown represent what has been graded so far for the term. There
may be assignments that have been handed in, but have not yet been scored or
