A degree in chemistry, in addition to being an excellent preparation for industrial employment, graduate study or secondary teaching, also prepares students to apply for further study in the areas of medicine, law, business administration, government service and agriculture science. To this end, the department offers a variety of introductory and advanced courses.

CHEM 125 is intended as an introductory chemistry course for all natural science majors.  It provides students with a comprehensive survey of chemical structure and ensuing chemical and physical properties that arise from structure.  Chem 125, together with the separate lab course Chem 201, fulfills the Common Curriculum Natural Science requirement.  200-300 level courses are intended for the students seeking a major or a minor degree in chemistry; they also serve as supporting courses for students majoring in biology, biochemistry, natural science, or nutrition science, and for pre-health profession students.

Students majoring in nutrition with a dietetics concentration should take CHEM 107 after taking CHEM 125. CHEM 105 and 107 do not meet the prerequisites for any other chemistry course.

The Chemistry Department is in the midst of a major change in its curriculum that will result in changes in the required courses for science majors taking courses past CHEM 125. These changes will start in Spring 2012 and continue through Spring 2014. First year students enrolling in Fall 2011 will be the first to complete the full four years of the new curriculum. In addition, the American Chemical Society (ACS) has changed course requirements for students taking the ACS-certified Chemistry Major. These latter changes will affect students graduating in Fall 2011 or later. In the new curriculum, all lab courses, except for CHEM 234, are stand-alone courses not attached to another course. Please consult the latest electronic versions of the course catalog for the most recent course changes as they are officially approved by the CSB/SJU Curriculum Committee.

Assessment

Each year, the Chemistry Department assesses its overall program and its students in a number of ways. For example, several courses employ standardized final exams for which there are national norms. All chemistry majors are required to take a nationally-normed exam (CHEM XXX) in the spring of their senior year. In addition, senior majors are asked to complete an anonymous survey to probe the extent to which they believe the department meets its stated goals and objectives. Every five years, the department must be re-accredited by the American Chemical Society, and, at similar intervals, departmental alumni are polled to obtain their evaluation of the education they received in the department. All of this information is employed to improve our program and ensure that the educational opportunities we provide are the best possible. Based on our assessment program and new Common Curriculum requirements, we will continue to make changes in courses and requirements that will promote student learning.
