Syllabus and general information for
MCS-178: Introduction to Computer
Science II (Fall 2007)
Overview
In MCS-178 we continue exploring the perspectives and methods of
computer science, particularly abstraction. We'll first consider the
notion of computations with changing state by looking "under the hood"
at computers. We'll extend this notion of state into other areas,
such as the use of state to construct more efficient computational
processes than otherwise, and the use of object-based and
object-oriented programming to model systems of objects with changing
state. Along the way, we'll also confront language issues, by
investigating how one might write and modify a Scheme system in Scheme
(a so-called meta-circular evaluator) and by introducing a second
programming language, Java. At the end of the semester we'll take a
brief look at using Java in writing event-driven and concurrent
programs (those that behave in response to user actions and those that
do more than one thing at a time).

Prerequisites
MCS-177: Introduction to Computer Science I.
Text and readings
The primary text for the course will be
Concrete
Abstractions: An Introduction to Computer Science by Max Hailperin,
Barbara Kaiser, and Karl Knight. We will cover chapters 10-15.
There's also an on-line Java Tutorial at http://java.sun.com/docs/books/tutorial/
,
and copies of several Java books in
the MCS Lab monitors' room, any of which you are welcome to use as a
supplement to the material on Java in our book.
All course handouts, as well as some supplementary materials,
will be available through the class web page
http://www.gac.edu/~mc28/F2007/index.html.
Course structure
Classes will be on Mondays, Wednesdays, and Fridays; except in the
last week of the semester, labs
will be held Tuesdays and Thursdays.
Note that all Monday/Wednesday/Friday sessions will be during 1:30-2:20pm,
even when (at the end of the semester) they are in the lab.
Labs will be held in the OHS 326 lab, using the Linux computers.
Tests
The two intra-term exams will be conducted during the evening from
7:30-9:00pm on October 4 and 26, both in OHS 321.
Please let me know as soon as possible if you
won't be able to take the tests at those times.
The final exam will be as scheduled by the registrar;
a tentative date and time is shown in the syllabus.
Mastery homework
The syllabus shows due dates for six homework assignments; each will
typically consist of four or five problems. You must turn in all the
problems in an assignment by that assignment's due date, but may turn
in individual problems earlier if you wish. I will mark each problem
as "mastered" or "not yet mastered," and return them to you as rapidly
as I can. For those not yet mastered, I may write some brief
indication of what area needs work, but you should really take these
as an invitation to come talk. You may turn in a revised version of
each problem however many times it takes to reach the "mastered"
point, even after the original due date. The only restrictions are
these:
- You must have submitted an initial attempt by the original due
date.
- No revision will be accepted for homeworks 1 and 2 after 1:30pm on
October 3rd, for homeworks 3 and 4 after 1:30pm on October 25th,
or for homeworks 5 and 6 after 1:30pm on December 14st.
These cutoff dates are intentionally
synchronized with the test reviews;
the point of the homeworks is to prepare you for the tests.
Note that if you turn in each homework problem as soon as you can do
it, rather than saving them for the assignment due dates, you will
have more opportunity for revision and resubmission before the cutoff
dates listed above. Particularly for the last homeworks before each
cutoff date (and test), I can't guarantee you'll have time for a
revision cycle otherwise.
I may also announce an earlier cutoff date for any individual problem
I consider important for us to discuss in class.
The homework portion of your course grade will simply be determined by
the fraction of the homework problems you eventually mastered.
Attendance policy
Attendance is mandatory for all lab sessions, unless you have already
turned in your project report. I will excuse up to two absences per
student, for any reason. Use yours wisely. If you exceed this
allowance, I may reduce your course grade by up to one letter grade.
Regarding class days, the policy is that you will be responsible for
all material, whether or not you are in attendance when it is covered
or distributed.
Honor
I expect you to adhere to the highest standards of academic honesty
and to uphold the
Gustavus Honor Code.
You are required to write
the honor pledge in full and sign it on every exam and lab report.
For co-authored lab reports, each author should write and sign the pledge.
Late lab assignments
All lab assignments are due at the beginning of class on
the day indicated. Late assignments will be penalized by one "grade
notch" (such as A to A- or A- to B+) for each weekday late or fraction
thereof. However, no late assignments will be accepted after I've
handed graded assignments back or discussed the assignment's solutions
in class.
If you are too sick to complete an assignment on time, you
will not be penalized. Simply write "late due to illness" at the
top of the assignment, sign your name and hand it in. Other circumstances
will be evaluated on a case-by-case basis.
Grade changes
Please point out any arithmetic or clerical error I make in grading,
and I will gladly fix it. You may also request reconsideration if I
have been especially unjust.
Grading
I will provide you with a grade on each lab
assignment and on each test, in addition to the mid-term and final
grades, so that you may keep track of your performance. As a
guideline, the components will contribute in the following proportion
to the final grade:
- 36% lab assignments (6 @ 6% each)
- 16% homework (see above)
- 48% exams (3 @ 16% each)
Please see me if you have any question how you stand.
Style guidelines
All homework and project reports should be readily readable, and should
not presuppose that we already know what you are trying to say. Use
full English sentences where appropriate (namely almost everywhere)
and clear graphs, tables, programs, etc. Remember that your goal is to
communicate clearly, and that the appearance of these technical items
plays a role in this communication process. Be sure your assignments
are always stapled together and that your name is always on them.
Each project assignment will include specific expectations for that
project's report, including the audience for which it should be
written. You should pay careful attention to this information.
