Online Homework Assignments (see p. 4 for access instructions):
We will use the ALEKS online Homework system in a "responsive" (rather than
"responsive/adaptive") format. The former option, which was recently incorporated into
ALEKS, gives each student essentially the same end-of-chapter problems (selected by the
instructor), with different numerical values or sample molecules. There are 6 online
homeworks with a total of 200 questions worth 0.1 point each. The maximum score that
can be earned is 15.0 points. (You can ignore the ALEKS pie.) That is, if you have
completed 150 out of the 200 questions by their due dates, then you have earned the
maximum possible points. (It is useful to do the other questions too, for additional
practice and to prepare for Quizzes and the Final.)
The "Initial Knowledge Check" (IKC) and the Math Review (48 topics), which do not
earn any points, are based on 48 math topics chosen to help students review aspects of
their high school math that may be useful when solving problems this semester. If a
student answers the first 10 or so of the IKC questions correctly, ALEKS may decide that
further review is not needed. If a student's incorrect answers indicate that more math
review would be useful, then more questions will be presented. Thus, it is most efficient
to answer the initial questions carefully, after working them out on paper. ALEKS
estimates that the average student will spend 2 ½ hours on this IKC.
Our online Homework assignments (A through F) will generally be due on alternate
Fridays (by 11:59 pm) on non-Quiz weeks; see the class schedules on pp. 19 - 20..
(An exception is Homework F, which is due the last day of classes, Mon. April 29.)
Each Homework (except the last one) can be submitted a week after its due date, with a
20% point penalty.
Homeworks B through F include some material covered on a Quiz given before that
Homework's due date. For example, Homework A, due Fri. Feb. 2, covers material in
the first chapter we will cover, Chapter 5, on the history, interpretation and applications
of the ideal gas law. Homework B, due Fri. Feb. 16, covers Chapter 6 on thermo-
chemistry. Our first test, Quiz 1 on Wed. Feb. 7 or Thurs. Feb. 8, will cover the material
in Chapters 5 and 6 (although Homework B on Chapter 6 is due later). So, it is a good
idea to do the relevant Homework problems before taking the Quiz covering those topics.
On the ALEKS Homeworks, students have 2 "question attempts" (which may have
different numerical values or sample molecules), and 3 tries per question attempt. A
second "assignment attempt" is also available, in which questions previously answered
incorrectly can be tried (3 times) again, and the better score counts. After submitting each
Homework, the problems can be redone for practice an unlimited number of times.
