## Graduate Degrees Offered

- M.S. in Informatics
- M.S. in Mathematics
- M.S. in Mathematics Teaching
- M.A.T. (emphasis in Mathematics or Computer Science)

The Department of Mathematics and Computer Science offers graduate studies leading to the following degrees: Master of Science in Informatics, Master of Science in Mathematics and Master of Science in Mathematics Teaching.

The Master of Science prepares the student to enter the workforce or to pursue doctoral degree programs in informatics, data science, mathematics, statistics, applied mathematics, or related fields.

The Master of Science in Mathematics also provides the student an opportunity to include computer science and statistics in the plan of study. An emphasis in applied mathematics is available for those desiring to pursue further graduate study, pursue a career in a mathematics-related area in industry or government, or teach at the community college level. An emphasis in statistics is available for those interested in careers as applied statisticians or statistical programmers.

The Master of Science in Mathematics Teaching is especially designed for elementary or secondary school teachers of mathematics. Course work emphasizes topics needed for the elementary or secondary mathematics teacher. The department also provides a plan of study designed to prepare current teachers for Master Mathematics Certification at the 4-8 or 8-12 level.

The Master of Arts in Teaching (M.A.T.) degree offered through the College of Professional Education prepares graduate students to be future mathematics teachers at the 4-8 or the 7-12 levels in mathematics or the 8-12 level in computer science. Mathematics or computer science courses required for the degree are determined in consultation with a departmental advisor.

### M.S. in Informatics

Informatics is the study and application of information science, computer science, cognitive science, and organizational science to the arts, sciences, and professions. The Master of Science program in Informatics at TWU provides students with a flexible, adaptable, interprofessional, and interdisciplinary approach to the study of Informatics in a hybrid learning environment.
