Computer Science 153 studies basic concepts of computer science, with an emphasis on problem-solving techniques from functional and object-oriented perspectives. Functional elements include data types, procedures as first-class objects, recursion, and binding. Classes, objects, and methods are introduced as basic elements of object-oriented problem solving. Examples of core data types and classes include stacks, queues, priority queues, trees, and lists. Additional topics include the representation of data and some elements of algorithm analysis.
Problem-Solving Perspectives: Computer science recognizes four problem-solving approaches as being fundamental to work in the discipline. Each approach involves a distinct way of thinking, and each is supported by a range of computer languages. These paradigms may be outlined as follows:
Since different approaches have advantages for different problems, people involved with computing should be comfortable with several of these paradigms.
A Comparison of CS 151-152 with CS 153:
At Grinnell College, the first courses in computer science (CS 151-152 or CS 153) introduce the functional, imperative, and object-oriented paradigms.

Optional Java Resource: During the first half of the semester, a textbook for the Java programming language will be identified as an optional resource for use in the second half of the semester.
Also, Sun's on-line Java documentation and manual provides useful information about the Java programming language. Two helpful sites follow:
While the schedule for this course is expected to evolve, a Tentative Class Schedule is available in dvi , postscript, and pdf formats.

Course Work will involve a combination of the following activities.
Supplemental Problems extend the range of problems considered in the course and help sharpen problem-solving skills. Through the semester, eight supplemental problems will be required. Supplemental problems numbered 9 or above may be done for extra credit, although extra credit may not raise a student's average on assignments above 120%.
Approximately ten labs require a formal write-up, explaining what work you have done, showing any programming you have done, indicating tests or experiments run, and giving your conclusions. Labs designated [Req] on the Tentative Class Schedule are required -- labs designated [EC] may be done for extra credit. In order for extra-credit labs to provide reasonable benefit, any such lab being submitted for credit must be turned in within 2 weeks of when it is scheduled for coverage in class. As with written homework, extra credit may not raise a student's average on laboratories above 120%.
Many lab activities should be done in groups of two or three, although you may work individually on labs after Lab 8. Only one write-up is expected per group.
Deadlines are shown on the Tentative Class Schedule , and work is due at the start of each class specified. A penalty of 25% per class meeting will be assessed for any assignment turned in late, even work submitted at the end of a class. However, an extension of at least one class period is automatically granted if MathLAN is down for an unscheduled period for a period of three or more hours during the week preceding the assignment. Normally, a program, project, or laboratory write-up is due every third class meeting.
Absolute Deadline: All homework must be turned in by Friday,
14 December at 5:00 pm;
laboratory reports or programs received after that time will not be counted in the grading of the course.
The work in this course is split between individual and group work. Students are encouraged to work together on all laboratory activities and on the simulation project. However, since a primary goal of the course is to enable students to develop their own programs, collaboration is not allowed on supplemental problems, the CGI project, or tests. In addition, students should note the department's policy regarding the role of technology-consultants for Computer Science 153 .
The final grade will be based upon each student's demonstration of his or her understanding of and facility in programming, not on the performance of the class as a whole nor on a strict percentile basis. While some flexibility may be possible in determining a final semester grade, the following percentages approximate the relative weights attached to various activities in this course.
