Quantitative Reasoning and Technological Literacy

Menu

The purpose of the Quantitative Reasoning and Technological Literacy (QRTL) at DePaul University is to help DePaul students to become confident and critical users of quantitative information of all kinds.

The program addresses the growing need for quantitative and computer literacy in response to the enormous expansion in the use of quantitative methods and information in the social and physical sciences as well as civic life. The use and misuse of quantitative information in public policy and scientific issues are particularly emphasized; students are taught to recognize the limitations of the quantitative methods as well as the insights they provide. Students learn by working with data sets from many different disciplines, such as psychology, environmental science, economics, finance, sociology, history. Students write critiques of quantitative arguments, gather data and present arguments of their own. The course is taught by instructors from many disciplines; psychology, communication, geography, history, mathematics and computer science. QRTL provides a solid foundation upon which subsequent courses in the disciplines and the Liberal Studies Program can and must necessarily build.

In the first year, students begin a two-course sequence comprised of the following courses:

Course Title Quarter Hours
LSP 120QUANTITATIVE REASONING & TECHNOLOGICAL LITERACY I4
LSP 121QUANTITATIVE REASONING AND TECHNOLOGICAL LITERACY II4

Some students may be required to take preparatory math classes before being eligible to enroll in QRTL courses, while other students may have one or both QRTL courses met by AP scores, transfer credit, or proficiency tests. Majors that require calculus do not require QRTL.​

QRTL Waiver

Readiness for LSP 120 is determined by the math placement test taken online after admission. Students may need to take developmental coursework prior to LSP 120. The LSP 120 requirement may be waived by credit already earned for advanced math coursework or by passing a dedicated proficiency exam. Students who complete both LSP 120 and LSP 121 take one less Learning Domain course. Students may not apply the course reduction to any Domain where only one course is required, and if taken within the SI Domain, the reduction cannot be applied to the SI Lab or SWK requirement.
