Students will:

  1.  Know how to think logically and mathematically
  2.  Have the ability to construct formal proofs in propositional and predicate logic
  3.  Have the ability to judge the validity of arguments
  4.  Have the ability to construct algorithms
  5.  Have the ability to assess the complexity of algoithms
  6.  Have the ability to use abstract structures to represent discrete objects and their interrelationships
  7.  Have the abiltiy to model using sets, functions, relations, trees, and graphs.


CSE 261 substantially supports the following student enabled characteristics:

A. An abiltiy to apply knowledge of computing and mathematics appropriate to the discipline

Assessment Plan for the Course

The students are given 10 medium-length homework assignments, two one-hour and fifteen minute tests, and a three-hour final examination. Each homework assignment typically covers two topics, and each test has seven questions. The final examination typically has eighteen questions and covers the whole range of topics. The performance of each student on each assignment and test and the final is rigorously tracked. Mean scores are computed for each assignment.

How Data in the Course are Used to Assess Program Outcomes:(unless adequately already in the assessment discussion under Criterion 4)

Each semester I include the above data from the assessment plan for the course in my self-assessment of the course. This report is reviewed by the Curriculum Committee of the CSE Department.
