CS Curriculum Revisions 2019-2020
This page lists proposed changes for the CS programs. A few guiding principals...
- BS - widen the split between the computing science and information science concentrations - making the IS concentration more doable/attractive to more students, firming up the foundations in the CS concentration, adding a data mining concentration.
- MS - new data science concentration, streamline academic concentration
- BS and MS - shift some key courses to be 4-5 hour courses, ensuring a stronger foundation for more students.
- 1 CS Undergraduate Majors/Minor
- 2 CS MS Major
- 3 Teaching Schedule
CS Undergraduate Majors/Minor
CS 401 Programming for Data Science - CS 501 exists, need to create CS 401 and decide on prereqs.
CS XYZ - Programming for the Sciences - check with NSM chairpersons on what they would want (something with CS 151 as a prereq, or what, is there something they would recommend their majors take?).
CS 305 - Computer Science Teaching Methods - to be used in CS Education minor - model syllabus.
New Minor - CS Education
Proposal for CS Ed minor is - CS 101, CS 151, CS 260, CS 305 Computer Science Teaching Methods, ECT 173 - Fundamentals of Information Technology. Mapping from courses to licensing exam

Stats - Math 241 or 341 (3)
Math 131, 132 Calc I, II (8)
101 Fundamentals of Computing (3)
Math 131, 132, 231 Calc I, II, III (12)
Note - courses that are currently part of the major that no longer would be - CS 420 Theory of Computation, CS 421 Formal Methods, CS 451 (changes to become CS 351).
Note - courses that we haven't offered in a while - CS 440 Graphics Programming, CS 463 Compilers - what should we do with them?
Note - current major is 51-53 credit hours, including 3 credits of 300 level and 25-28 credits of 400 level. Proposal would be for 50-54 credit hours, including 9-12 credits of 300 level and 16-22 credits of 400 level. Students need 45 300-400 level credits overall to graduate. Students will normally have at least about 12 credits of 300-400 level courses as part of Foundational Studies.
Note - calling new concentration "Data Mining" at the request of chairperson, so we don't use the same name "Data Science" as a new BS program that is being proposed by the department.
Question - create a Data Mining certificate and/or minor? Would there be demand for this?
Question - electives?
- 101 or 151 -> CSS 210, CSS 211, CSS 311
