MIT's OpenCourseWare initiative has garnered favorable mentions from educators around the world since its inception several years ago, and new material is added to the site every semester. One recent addition to the site was this particular set of materials for an introductory course on electronics. Under the direction of Professors Manos Chaniotakis and David Cory, this course is designed as a "practical-hands on-introduction to electronics with a focus on measurement and signals." Included on this site are a set of lecture notes, laboratory assignments, review notes, and practice exams. While students from around the world could definitely benefit from this material directly, educators could also peruse this material in an effort to gain some sense of how they might structure their own course.
