Enrollment Program for Math~Summer Workshop~

Each summer the LSU College Readiness 8-day Summer Workshop for Math is held for first-time DE teachers.

Schools participating in LSU DE can send other math teachers from their school to the workshop to get certified for other courses.

The workshop focuses on three areas: Math Content: Teachers have access to homework for each

course that can be customized into any groupings for units, quizzes, and tests

Redesign Pedagogy: Group presentations and individualized instruction

Technology Training: MyMathLab online learning system
