In a previous issue of "The Physics Teacher", John Hubisz explained how a mathematics background check has been used at three different colleges to determine the appropriate physics sequence for incoming students. Based on their performance, students are placed into either calculus-based physics (CBP), algebra-trig physics (ATP), or a year of conceptual physics (CP). By placing the mathematically less-prepared students into either ATP or CP, Hubisz notes, higher success rates in CBP have been observed.
