Circuits Learned by Example Online (CLEO): A video-based resource to support engineering circuit analysis courses

The "circuits learned by example online" (CLEO) web-based repository of over 250 worked problems in engineering circuit analysis provides students with a video-based learning tool suitable for self-guided study, homework support, and exam preparation. Each problem offers the complete solution process embodied as a narrated video "screencast" of handwriting and drawings captured from a tablet device; the audio commentary explains each step of the multistep solution process. The searchable repository matches the organization of leading circuit textbooks, and can also be tailored to a specific course syllabus. Many examples of correct problem-solving strategies are presented, including explanations of why specific strategies are selected among competing approaches. Students report that they consider the CLEO system a useful resource to support their homework activities, as a tutorial to learn more about concepts presented in class, and as preparation materials for exams. Students also reported that the system helped them to better understand course concepts, make efficient use of study time, and improve their problem solving skills.
