Redesign of Developmental Mathematics THE UNIVERSITY OF ALABAMA College of Arts and Sciences Department of Mathematics NCAT Redesign Workshop March 17, 2008
Setting • 2 developmental math courses • Intermediate Algebra • Remedial Mathematics • 1700 students per year • Taught in traditional, lecture-based setting • Taught entirely by instructors and GTAs
Course Format • Courses taught in rigid format • Common syllabus • Common presentation schedule • Common tests
Problems • Courses teacher-centered • No support for multiple learning styles • Inconsistent coverage of topics • No flexibility in instructional pace • Lack of student success • Very high course repeat percentage • Negative impact on student retention • Significant drain on resources
Solution • Identify an alternative structure that: • Had faculty and instructor support • Was learner centered • Supported multiple learning styles • Provided consistent presentation of material • Allowed students to work at own pace • Increased student success • Reduced resource demands
Approach Selected • “Math Emporium” model developed by Virginia Tech • Initial application to Intermediate Algebra (Math 100) • Approximately 1300 students per year
Course Format • 30-50 minute “classes” that introduce students to topics and integrate the topics into the overall course objectives • 3-4 hours in Mathematics Technology Learning Center (MTLC) or elsewhere working independently using course software that presents topics covering specific learning objectives • Instructors and tutors available in MTLC 71 hours/week to provide individualized assistance
Course Format (continued) • Students review topic material • Students work homework problems that cover defined learning objectives • Homework is graded immediately by the computer providing the student with instant feedback on their performance • After completing homework, students take quizzes that cover learning objectives
Course Format (continued) • Students can do homework multiple times and take quizzes twice, always receiving instant feedback • After completing homework and quizzes on a series of topics, students take a section test • Tests are given only in the MTLC • Tests available on demand with a specified completion date
Fundamental Premise Students learn mathematics by doing mathematics
Advantages of Course Format • Learner-centered • Software supports multiple learning styles • Consistent presentation of material • Individualized tutorial support available • Students can work at own pace
Advantages of Course Format • Students can work in lab or at home • Software provides instant feedback on work • Homework, quizzes, tests, & exam computer graded • Software records all student activity

Traditional Course Cost 2001-2002 Academic Year - 1480 Students 43 Sections of 35 Students Each 2 FTTI (16 sections) @ $36,250 $72,500 5 GTAs (20 sections) @ $17,565 $87,825 7 PTTI (7 sections) @ $1,655 $11,585 Total Cost $171,910 Cost Per Student $116
Redesigned Course Cost 2001-2002 Academic Year - 1480 Students 18 Sections of 85 Students Each 2 FTTI @ $36,250 $72,500 6 PTTI @ $1,655 $9,930 UG Tutors 5760 hrs @ $7/hr $40,320 Total Cost $122,750 Cost Per Student $83
Cost Savings Traditional Course $116/student Redesigned Course $83/student Savings $33/student (28%)
Cost Savings(Economy of Scale) 955 Students in Math 005 & 112 1 FTTI @ $36,250 $36,250 4 PTTI @ $1,655 $6,620 Total $42,870 $45/student
Cost Savings(Reduction of Course Repeats) 1480 Students in Math 100 20% increase in success rate = 296 students 296 students @ $116/student = $34,336
Cost Savings (Room Availability) 2001-2002 Academic Year - 1480 Students Traditional Course 43 Sections of 35 Students Each 43 sections X 3 hr/wk = 129 classroom hours Redesigned Course 18 Sections of 85 Students Each 18 sections X 1 hr/wk = 18 classroom hours Savings = 111 classroom hours (37 3-hr/wk course slots)
Conclusions • Based on our experience, we are confident that computer-based instruction in precalculus mathematics courses can: • Enhance student learning • Increase success rates, particularly for underserved students • Reduce resource demands
