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)
Fall 2010 Phase I: Survey Responses from
213 colleges and universities
502 instructors representing 663 Calculus I classes and 26,257 students

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%
Men in Engineering A or B: 2% C: 7%

8 Common Features of Calculus Programs at Selected PhD Granting Institutions
1- Rigorous courses 2- Attention to local data 3- Solid GTA professional development 4- Support for active learning 5- Coordination of courses 6- Strong student support services 7- Attention to placement issues 8- Regular meetings of course instructors

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
