The mole is an important theoretical concept and a powerful tool in the study of chemistry. Traditional approaches to teaching the mole focusing on memorization and rote learning do not help students to develop the conceptual understanding and problem-solving skills necessary to be truly successful in chemistry. An alternative approach is to use discovery-oriented laboratory exercises for helping students to develop an intuitive understanding of moles. Once students have discovered for themselves the utility and power of moles, the reason for using moles becomes obvious. Additional open-ended experiments provide students with the opportunity to apply this knowledge base in a non-directed laboratory setting.

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
