The Modular Electronics Learning (ModEL) project represents the culmination of over two decades of professional instruction in the field of industrial electricity and electronics. It is substantially different from earlier publications such as Lessons In Electric Circuits in multiple ways.

First, the tutorials seek to explain as much as possible about electric and electronic circuits from first principles such as physical Conservation Laws. Second, each complete module contains multiple tutorials approaching the topic from different perspectives and levels of complexity (e.g. Introduction, Case Tutorial, Simplified Tutorial, Full Tutorial). The Tutorial chapters strive to apply fundamental concepts and problem-solving strategies at every opportunity so that readers emerge with a strong conceptual foundation. Third, some modules additionally contain Historical References and/or Animations chapters providing further exposition and context. Fourth, each modules contains question sets, projects, and experiments in order to be a comprehensive learning tool. These application questions specifically address qualitative, quantitative, and diagnostic modes of thought in order to encourage well-rounded development of the reader's understanding. Finally, these modules showcase the use of computer-based simulation tools, especially SPICE and text-based computer programming languages such as C, C++, and Python, as an aid to exploration of circuits and their underlying principles.
