This document introduces electronic lessons (E-Lessons) created by R.D. Sivakumar and K. Sivakami. E-Lessons are animated teaching materials developed based on research in cognitive development, learning theories, and pedagogies. The goal is to provide learners with a tool that accelerates learning. For learners, E-Lessons offer an unusual way of learning that helps them remember lessons, track their progress, and gain confidence. For teachers, E-Lessons add variety to teaching, help address different abilities, allow teaching outside the classroom, and save time and energy.
