OldHawk777 writes with news that MITx, the Massachusetts Institute of Technology's online learning initiative, has opened free enrollment for its first course: 6.002x: Circuits and Electronics. "Modeled after MIT’s 6.002 — an introductory course for undergraduate students in MIT’s Department of Electrical Engineering and Computer Science (EECS) — 6.002x will introduce engineering in the context of the lumped circuit abstraction, helping students make the transition from physics to the fields of electrical engineering and computer science. ... 'We are very excited to begin MITx with this prototype class,' says MIT Provost L. Rafael Reif. 'We will use this prototype course to optimize the tools we have built by soliciting and acting on feedback from learners.' To access the course, registered students will log in at mitx.mit.edu, where they will find a course schedule, an e-textbook for the course, and a discussion board. Each week, students will watch video lectures and demonstrations, work with practice exercises, complete homework assignments, and participate in an online interactive lab specifically designed to replicate its real-world counterpart. Students will also take exams and be able to check their grades as they progress in the course. Overall, students can expect to spend approximately 10 hours each week on the course."
