PRIMUS (Problems, Resources, and Issues in Mathematics Undergraduate Studies) is a leading journal for exchanging ideas about teaching collegiate mathematics. PRIMUS publishes lively and engaging articles for a readership comprised primarily of practitioners. The journal’s focus is on pedagogical initiatives in college-level mathematics, mathematics education, and elementary statistics ranging in scale of application from individual students and courses to curricula and entire programs. Articles published in PRIMUS typically present a novel idea, evidence that the idea supports student learning, and indication that the idea is transferable to other faculty, courses, or institutions. PRIMUS also publishes survey articles on relevant mathematics or teaching endeavors, exploration and assessment of particular pedagogical approaches, and accounts of programmatic endeavors that affect multiple courses or courses across institutions; in every case, the goal is sharing information to improve undergraduate teaching and student learning in mathematics.
