In education, a "module" is a fractional part of a student's education experience. In an entire degree program, each class represents a module focused on a given subject. In a single class, a module is a chapter, class meeting or lecture on a specific topic.
In a four-year business degree, it is common that students complete course modules in areas like economics, accounting, marketing, management and finance. In a science degree, modules include physics and chemistry. In a math course, students may complete modules in addition, subtraction, multiplication, division and word problems. Each module contributions to broader learning goals in the subject.
