MyMathLab Course Structure

Course Design

Courses are offered both on-site and online. All students use MyMathLab for homework; on-site students are required to spend a minimum of 12 hours per semester in the lab. Some instructors give quizzes.

Assessments

There is an in-class test for each chapter. Intermediate Algebra includes a midterm. All courses include a comprehensive departmental final examination.

MyMathLab Implementation

MyMathLab homework and quiz features are used and contribute 15 percent to each student’s final course grade. After MyMathLab implementation, online enrollment increased from 1.6 percent to 14.75 percent. Grades are imported from other sources.

Conclusions

The positive change in pass rates indicated by Table 2 points to the conclusion that required use of MyMathLab increases success and retention rates. Plans include a study to ascertain the effects on pass rates when more-in-depth use of the program—such as videos, study plans, and PowerPoints—are required as well.
