The Department of Mathematical Sciences offers the B.S. degree with a major in mathematical sciences with emphases in general mathematical sciences, applied mathematics, computational mathematics, probability and statistics, and mathematics education. Successful completion of the emphasis in mathematics education leads to certification to teach at the 6-12 grade levels.

The department also offers minors in mathematical sciences and in applied probability and statistics. These minors should be of interest to students majoring in the physical or social sciences or in business. In addition, the department offers an honors program in mathematical sciences and participates in the University Honors Program.

All students interested in the emphasis in probability and statistics or in actuarial sciences, a degree with honors in probability and statistics, or a minor in applied probability and statistics should contact the office of the Division of Statistics.

Several of the department's courses fulfill the university mathematics core competency requirement and others can be used by non-majors toward fulfilling the sciences and mathematics area requirement in the university's General Education Program. In addition, many of its courses are included as requirements for other programs.

Mathematical sciences majors are not permitted to count courses in computer science (CSCI) toward fulfilling general education area requirements.

For all majors in the department, the GPA in the major is calculated by using only those mathematical sciences courses numbered 229 or above which are available for credit toward the major.

Students majoring or minoring in mathematical sciences must obtain a minimum GPA of 2.00 in those MATH/STAT courses applicable to that major or minor. Courses not applicable to the major or minor are identified in the course descriptions.

All majors are required to have a satisfactory portfolio of work done during their undergraduate studies on file in the Department of Mathematical Sciences. The contents of the portfolio are to be used to assess the department's program and are to be accumulated largely through course work assignments and examinations; students are expected to cooperate with instructors as these items are collected. In addition, each student must submit in his or her senior year a 250-300 word typed essay describing the student's experience in the major, including comments on the connections of mathematics with other disciplines. Details on the submission of materials and approval of the portfolio should be obtained from the student's adviser in the Department of Mathematical Sciences.

Students planning to take MATH 110, MATH 155, MATH 206, MATH 210, MATH 211, or MATH 229 must take the Mathematics Placement Examination, so they may begin their mathematical studies at the appropriate level.

Ordinarily students will not be allowed to attempt a proficiency examination for a course if they have received credit for a higher numbered course (for exceptions, consult the department).

Successful completion of the emphasis in mathematics education leads to certification
to teach at the 6-12 grade levels. In addition to the course work and certification
requirements in the Department of Mathematical Sciences, students must complete other
course work and certification requirements outside the department. A minor which includes
a teaching endorsement in a teaching area outside of mathematics is highly desirable to
enhance placement opportunities. All students who wish to pursue the emphasis in
mathematics education and to seek teacher certification should consult with an adviser in
the Department of Mathematical Sciences before the end of the sophomore year. Transfer and
postbaccalaureate students should see an adviser in the Department of Mathematical
Sciences on arrival. Graduate students majoring in the mathematical sciences, graduate
students majoring in secondary education, and students-at-large should consult the *Graduate
Catalog.*

1. Apply for admission to teacher certification in the Department of Mathematical Sciences. This is usually done three semesters prior to the semester of student teaching.

2. Pass the Basic Skills Test of the Illinois Certification Testing System in order to be formally admitted to the teacher certification program. This should be accomplished before taking MATH 412. An informational booklet about the test and registration materials for the test can be obtained from the Office of Testing Services.

3. Obtain departmental approval for admission to teacher certification. This is normally done through a conference with the coordinator of teacher certification in mathematics two semesters prior to the semester of student teaching.

4. Satisfy the minimum GPA requirements established by the department for the undergraduate emphasis in mathematics education: an overall GPA of 2.50, a GPA of 2.25 in all courses counted for credit toward the major, and a GPA of 2.25 in all courses counted for credit toward the major numbered above MATH 231.

Hours do not include general education requirements. The state of Illinois requires extensive work in general education for certification. In some cases these requirements exceed those required by the university for a baccalaureate degree. Therefore, students should consult with an adviser within the department as early as possible to ascertain all of the requirements.

The teacher certification requirements are the same for undergraduate mathematical sciences majors with an emphasis in mathematics education and for postbaccalaureate students seeking certification in mathematics without becoming a candidate for a degree. Admission to MATH 413, the student teaching course, is dependent upon the availability of resources.

All students seeking certification must pass the Illinois certification examination. Information about this test may be obtained from the Office of Testing Services.

The Department of Mathematical Sciences offers the exceptional student an opportunity to earn a degree with honors in any of the five emphases. Any mathematical sciences student may become a candidate for an honors degree in mathematical sciences at the end of the sophomore year provided the student has a 3.00 or higher overall GPA and has a 3.50 or higher GPA in all mathematical sciences courses completed, including MATH 232 and MATH 240.

A student with these qualifications who wishes to become an honors degree candidate should go to the office of the Department of Mathematical Sciences (or, in the case of students in the emphasis in probability and statistics, to the office of the Division of Statistics) to fill out a candidacy form and be assigned an honors adviser. After the end of the sophomore year, a student showing exceptional talent may also become an honors degree candidate by obtaining consent.

Most 300-level and 400-level mathematical sciences courses may be taken as honors courses.

Maintain a 3.00 or higher overall GPA.

Maintain a 3.50 or higher GPA for mathematical sciences courses numbered 300 and above.

Take at least four mathematical sciences honors courses numbered 300 or higher, which must include a two-course sequence of 400-level honors courses appropriate for the student's emphasis and approved by the honors degree adviser. The honors sequences from which a sequence appropriate for the student's emphasis may be chosen are MATH 420H-MATH 421H, MATH 420H-MATH 423H, MATH 430H-MATH 431H, MATH 434H-MATH 435H, STAT 470H-STAT 472H.

In one of the 400-level honors courses, prepare and submit an independent study paper on a suitable topic. The paper must be approved by the instructor of the course and by the honors degree adviser.

- MATH 229, MATH 230, and MATH 232, Calculus I, II, and III (12)
- MATH 240, Linear Algebra and Applications (4)
