Characteristics of Successful Programs in College Calculus

Three parts: 1.  National survey of students in mainstream

Calculus I and their instructors (Fall, 2010) 2.  Statistical model of factors influencing

changes in student attitudes and intention to persist from start to end of Calculus I

3.  Case studies of 18 institutions with “successful” Calculus I programs (Fall, 2012)

Switchers: students who started certain that they would go on to take Calculus II, but by the end of the term were no longer sure or had definitely decided not to continue.

Ellis & Rasmussen model of “switchers” Variables: gender, SAT/ACT math, previous calculus, intended major, institution type, good teaching, ambitious teaching, instructor type. Strongest predictors of switching: 1.  Female (1.68 times male) 2.  Low good teaching (1.54 times high) 3.  Taught by graduate student (1.43 times other)

Switchers by grade in Calculus I. Women:

A: 10% B: 13% C: 24% Men

A: 6% B: 6% C: 12%

Women in Engineering: A or B: 4% C: 19%

Progress through Calculus •  Restrict to departments with graduate programs in

Mathematics (Masters and/or PhD) •  Pre-Calculus through Calculus II sequence •  Multiple outcome measures (including pre- and

post-testing of student knowledge, tracking persistence, success in subsequent courses)

•  Focus on networking and observing departments that are reforming one or more courses in this sequence

Spring 2015, surveys on the precalculus through single variable calculus sequence sent to all 330 US math departments offering a graduate degree in mathematics. Response rates:

PhD departments: 134/178 = 75% MA departments: 89/152 = 59% Overall: 223/330 = 68%

Percentage of respondents using placement tool (could select multiple placement tools)

From 2010 to 2015, use of ALEKS for placement at universities with PhD programs has jumped from 10% to 28%. Adaptive questioning Includes focused instructional modules Opportunities for retesting Does not use multiple choice questions

Across all placement instruments 9% are not satisfied

39% consider them adequate, but could be improved

30% are currently replacing or have recently replaced their placement instrument(s)

29% are considering changing their placement instruments

Interesting approaches (in place or planned):""Illinois-Urbana/Champaign. Separate 5-credit

Calculus I for those who have not had calculus

Arizona & Michigan. Diversion to special precalculus class that starts after first exam

OK State. Diagnostic quiz after Calc I starts with easy switch to precalculus.

Florida, George Mason, Colorado-Boulder. Easy late switch to precalculus
