|The fields of mathematics, computer science, and information systems complement each other with a synergism that carries over into the relationships between students and faculty members in the department. We stress developing the student’s ability to think analytically and independently in all problems whether or not they are mathematical. We pursue developing the student’s aptitude for mathematical reasoning so that the student will be prepared for the pursuit of knowledge and truth beyond the boundary of the classroom. As the department offers its courses, it strives to be a place where students and faculty can study and learn in a cooperative, supportive environment.|

Visiting Instructor of Computer Science
Cathy A. Beicker began working at TLU in 1979. She worked part-time for Texas Lutheran while she taught math and computer science in public middle/high schools. She received her B.S. in Education with a major in Math and a minor in Computer Science in 1976. By Aug 1978, she received her M.A. in Math and Counseling Education. Mrs. Beicker joined TLU full time in 2012, after retiring from public education.
Cathy Beicker has taught at Randolph AFB(Schertz, TX), Seguin ISD(Seguin, TX), University of the Incarnate Word(San Antonio, TX), and Central Texas Technology Center(Clear Springs, TX).
Cathy Beicker’s personal interests lie in community work. She has been President of several community organizations--namely, the Seguin Sports Booster Club and the Seguin Education Foundation.
