Next Generation Science Standards and college level STEM coursework emphasize the application of science, technology, engineering design, and mathematics to promote reasoning and problem-solving skills applied in formulating potential solutions for real-world problems. One such problem relevant to students in grades 6-12 and at the introductory college level is successfully deciphering structures they attempt to view with microscopes and telescopes. Such experiences can become a frustrating

The goal of this module is to apply algebraic and geometric principles to elucidate stereology as it applies to making sense of 3-D images and 2-D cross-section images derived from the projection of 3-D images. The module builds student understanding through a series of visual demonstrations using basic principles used in imaging of structures with short didactic presentations to scaffold learning. Students construct physical models to demonstrate stereology and explain it in the context of microscopic images, and computer tomography (CT). Integrating algebra and geometry in relation to stereological phenomena is of importance in developing appreciation of mathematical application in scientific topics, a deeper understanding of technology applications in science, and more specifically in understanding the application of stereology in scientific imaging.
