Redesign of Precalculus Mathematics THE UNIVERSITY OF ALABAMA College of Arts and Sciences Course Redesign Workshop October 21, 2006
Setting/Problem Course History Course Format Outcomes Implementation issues Cost-Savings Conclusions Redesign of Precalculus Mathematics
Setting • 6 Precalculus math courses • 6500 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 • D/F/W rates as high as 60% • Very high course repeat percentage • Negative impact on student retention • Significant drain on resources
Issues • Tenure-track faculty not invested in precalculus courses • Courses damaging to department’s reputation • Solutions proposed required significant resources • Smaller class size • Increased support (graders, tutors)
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 History • Fall 1999 • Visited Virginia Tech • Began initial planning for course • course text/software - Intermediate Algebra by Martin-Gay/MyMathLab (Prentice-Hall)
Course History • Spring 2000 • Piloted redesigned format in 3 sections of Math 100 (100 students)
Course History • Summer 2000 • Received $200,000 Pew grant • Assigned a 70-seat computer lab to course • Established the Mathematics Technology Learning Center (MTLC) • Taught 5 sections of Math 100 (130 students) using redesigned format
Course History • Fall 2000 • Taught 18 sections of Math 100 in MTLC (1140 students) 1140
Course Format • 30-50 minute “classes” that introduce students to topics and integrate the topics into the overall course objectives • 3-4 hours in MTLC or elsewhere working independently using course software that presents a series of topics covering specific learning objectives • Instructors and tutors available in MTLC 71 hours/week to provide individualized assistance
Course Format (continued) • 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 and take quizzes multiple times and receive 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
Advantages of Course Format • Students can work at own pace • 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
Implementation Issues • Instructor Buy-In • Instructor Training • Detachment From Students • Student Engagement • “No Teacher” Syndrome • Staff Scheduling • Scheduling Deadlines, Tests, Etc. • Data Management
