The world wide web has been in existence for just over twenty-five years, but already its potential for impacting education appears to be infinite. Online platforms provide increasingly sophisticated tools for the mass dissemination of knowledge and sharing of ideas. These platforms can currently be accessed by the more than half of the people on Earth who have access to the internet in 2017, and the infrastructure for the internet continues to expand rapidly into developing global locations. Today, online learning is an important current topic for contemporary educators in diverse fields. The chapters in this book address these topics specifically for the field of chemistry, giving overviews of existing work as well as "snapshot in time" examples of the work being conducted in this area. The purpose of the book is to examine the relevant successes, challenges, research findings, and practical examples in online approaches to chemistry education.
