This module on the structure of the microscope 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 two learning experiences. Each learning experience contains an overview, an objective (e.g., after completing the required reading, identify the parts of the compound microscope and state the functions of each part), and two or three activities (e.g., read the information sheet on the history of the microscope; list, group, and label some additional magnifying objects). Information sheets are generally provided for each activity. To provide feedback to students, a self-check with model answers is included with each learning experience. A student performance assessment form for use by the instructor completes the module. (KC)
