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.

CS Undergraduate Majors/Minor

Overview

Note that the current major includes 10 courses required of all majors, 5 additional courses required for information science, 3 CS courses required of computing science, and 2 math courses required for computing science.

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 - current proposal for CS Ed minor is - CS 101, CS 151, CS 260, CS 305 Computer Science Teaching Methods, ECT 173 - Fundamentals of Information Technology.

Question - also add - programming for the sciences, with CS 151 as a prereq? Check with NSM chairpersons.

Question - DS concentration called Data Mining?
