HiPerCiC Collaborative Web Applications

Course number: ID 259
Status: Offered in Fall 2017.
Prerequisites: SD for CS students; prerequisites for non-CS students determined by instructor and faculty collaborators..
General Education: [WRI].
Role in major requirements: Elective.
Knowledge units: (for CS students) PF5 NC1 NC2 NC5 HC1 HC2 HC4 HC5 HC6 HC8 IM1 IM2 IM3 SP2 SE4 SE7 SE9 CN1 CN4
Revised model curriculum: Elective
Description:A project-based course in which interdisciplinary teams create web-based software systems that each provide a convenient user interfaces to high-performance computations of interest to students and faculty in an application area. Teams will be co-supervised by a CS professor and a professor in another discipline; CS students will implement the software in consultation with non-CS students and faculty, using the HiPerCiC (High-Performance Computing in the Classroom) framework; non-CS students will study the role of CS and high-performance computing in society; and all students will study project management practices.

Accelerated Principles of Computer Science (CS1+)

Course number: CS 225
Status: Offered by arrangement in the Fall.
Prerequisites: Advanced placement or substantial prior programming experience in C++ language, or consent of instructor.
General Education: [MAR/AQR].
Role in major requirements: Foundation course.
Knowledge units: PF1 PF2 PF3 PF4 OS5 PL6 PL7 SE1 SE3 SE4 SE5 SE7 SE8 SE10 SP3 (union of knowledge units for CS1 and SD)
Revised model curriculum: Computer Science I and II
Description:An accelerated course accomplishing the combined goals of CS1 and SD, for students with sufficient prior C++ programming skills. Includes a weekly laboratory meeting and a team project experience. Prerequisites: Advanced placement or substantial prior programming experience in C++ language, or consent of instructor.
Comments:
- Offered through Fall 2008.
- This course addresses the needs of students who have substantial programming experience in C++ or Java prior to enrolling at St. Olaf, such as students with Advanced Placement credit. The material of CS1 is new to these students, both in terms of concepts and programming language; however, such students can master this material more quickly than beginners. Also, these students do need little or none of the introduction to C++ programming included in SD, although they have not had the team project experience and exposure to ethical considerations that appears in that course. CS1+ serves such students by exploring CS1 material at approximately double pace, then treating C++ briefly and turning to a team project in the style of SD.

Mathematical Foundations of Computing (MFC)

Course number: CS 231
Status: Offered each Spring
Prerequisites: CS1. Students with especially strong or especially weak mathematical skills should check with the instructor..
General Education: [MAR/AQR]; may be offered for [WRI].
Role in major requirements: Foundation course.
Knowledge units: DS1 DS2 DS3 DS4 DS5 DS6 AL5
Revised model curriculum: compare to Discrete Mathematics
Description:A presentation of mathematical topics that form an essential background for the study of Computer Science. Functions, relations, basic logic, predicate calculus and formal reasoning, verification of programs, proof techniques, basics of counting, graphs and trees, discrete probability, introduction to computability. Prerequisites: CS1. Students with expecially strong or especially weak mathematics backgrounds are encouraged to check with the instructor.
Comments:
- The goal for MFC is to create a sufficient prerequisite for TC (and revisions to ADS). This goal is accomplished in part by taking advantage of the mathematical reasoning skills developed in CS1 (or CS1+), particularly those involving verification of programs.
- MFC includes a gentle introduction to mathematical proofs. Mathematics majors can use the course as a “warmup” for transition courses Math 244 and Math 252.
- MFC counts towards the Mathematics major as well as the CS major.

Hardware Design (HD)

Course number: CS 241
Status: Offered each Fall
Prerequisites: CS1.
General Education: None.
Role in major requirements: Foundation course.
Knowledge units: AR1 AR2 AR3 AR4 AR5 AR6 AR7 AR8 AR9 PL2

Virtual machines, overview of computer organization, forms of parallelism, machine-level representation of data, memory organization, digital logic, functional organization, microprogrammed and RISC architectures, performance enhancements and alternative architectures, assembly level machine organization and programming, architecture of networks and their protocols. Prerequisites:CS1, or consent of instructor.
Comments:
- Newly expanded emphasis on understanding of machine-level implementation of standard features of five popular programming languages, beginning in Fall 2010.
- Exposure to multicore programming included, beginning in Fall 2010.
- This course is an entry point to the major for students with advanced placement in computer science.

Software Design and Implementation (SD)

Course number: CS 251
Status: Offered each Spring semester.
Prerequisites: CS1.

Role in major requirements: Foundation course.
Knowledge units: SE1 SE3 SE4 SE5 SE7 SE8 SE10 OS5 PL6 SP3
Revised model curriculum: intersects with Computer Science II
Description:An introduction to the structure and creation of computer software, using C++ programming language and emphasizing object-oriented programming and software lifecycle methodology. Includes a weekly laboratory. Concepts and skills are applied in a team project based on the “waterfall model” of software development. Object-oriented programming, specification, high-level memory management, indirect addressing, formal methods, tools including UML, team software process, requirements analysis, software design strategies, elementary ethical analysis of software systems. Prerequisites: CS1, or consent of instructor.
Comments:
- Must be taken together with the laboratory SDL: sign up for SD and for one section of SDL in the same semester.
- The combination of CS1 and this course constitutes a two-term introduction to Computer Science that includes a survey of disciplinary principles, a solid foundation in computer programming (in two contrasting programming languages), participation in a team project based on sound software development methods, consideration and elementary analysis of ethical and social issues in computing, satisfying multiple general education requirements. This combination functions as a service sequence for students in other majors who may seek an introductory background in Computer Science for application to computing projects or out of general personal interest. If you intend to take two CS courses, CS1 and SD provide the best balance of concepts, practical skills, and insight into the world of computer software. See the reasons to take SD for more information.
- Besides serving non-majors, SD also opens the most doors for further study in CS. See prerequisites for the courses below.
- Planning note: This course doesn’t introduce as many new ways of thinking as CS1, but learning to program well requires a lot of “time on task” for homework and assignments related to the separate laboratory meeting. Be sure to allow for this extra time demand in schedule planning.

Software Design and Implementation Lab (SDL)

Course number: CS 252
Status: Introduced as a separate course Spring 2005
Credit: 0.25
Prerequisites: SDL.
General Education: None.
Role in major requirements: Foundation course.

Prerequisite: concurrent registration in SD.
Comments:
- Required laboratory for SD: sign up for SD and for one section of SDL in the same semester.

Algorithms and Data Structures (ADS)

Course number: CS 253
Status: Offered each Fall semester.

Prerequisites: SD or CS1+, or consent of instructor.
Comments:
- The description above refers to the existing course CS 372. In future offerings, emphasis on algorithm analysis will gradually increase. Beginning in 2005-06, MFC or comparable mathematical background will become an additional prerequisite to support this change.

Ethical Issues in Software Design (ESD)

Course number: CS 263
Status: Offered each Spring.
Prerequisites: SD (or CS1+).
General Education: [ORC], [EIN].
Role in major requirements: Core course.

Prerequisites: SD or CS1+, or consent of instructor.
Comments:
- While other courses in the curriculum raise general awareness of ethical and social concerns in computing and may involve elementary analysis of ethical impact, this course examines such issues more formally and in depth. The CS1+/SD prerequisite not only takes advantage of the introduction to ethical and social matters present in those courses, but also enables more extensive exploration of those issues, since students are knowledgeable about the practice and methodologies of team software development.
- This course carries [ORC] and [EIN] general-education credit. To receive the [EIN] credit for CS 263, the [BTS-T] requirement must be satisfied before or during the term in which you take CS 263.

Comments:

Theory of Computation (TC)

Course number: CS 333
Status: Offered alternate years in the Spring. Next offering Spring 2011.
Prerequisites: MFC.
General Education: None.
Role in major requirements: Core course.
