PRIMUS: Problems, Resources, and Issues in Mathematics Undergraduate Studies (print: ISSN 1051-1970, online: ISSN 1935-4053) is a peer-reviewed academic journal covering the teaching of undergraduate mathematics, established in 1991. The journal has been published by Taylor & Francis since March 2007 and currently has eight issues per year. Its primary interest is in first person descriptive and narrative articles about implemented teaching strategies and interesting mathematics, but broad survey articles, formal studies of new teaching approaches, assessments of planned and in place strategies, and general discussion of teaching undergraduate mathematics are also published. The journal is abstracted and indexed in Cambridge Scientific Abstracts, MathEduc, PsycINFO, and Zentralblatt MATH.
