This module on medical terminology (using common prefixes, suffixes, and root words) is one of 17 modules designed for individualized instruction in health occupations education programs at both the secondary and postsecondary levels. This module consists of an introduction to the module topic, a list of resources needed, and three learning experiences. Each learning experience contains an overview, an objective (e.g., after completing the required reading, use some common medical terms and identify these terms with their proper meaning), and two activities (e.g., study the list of medical terms and their meanings; practice writing the medical term and its meaning). Information sheets (such as word lists and puzzles) are generally provided for each activity. To provide feedback to students, a self-check with model answers is given for the first two learning experiences; a student performance assessment form for use by the instructor follows the third learning experience and completes the module.
