BOOKS ON TCK'S:
Third Culture Kids: Growing Up Among Worlds by David C. Pollock and Ruth E. Van Renken
A secular book dealing with all types of TCKs, Pollock and Van Renken have created an excellent resource which should be in the library of every missionary with children. The first section describes TCKs and CCKs (Cross-Cultural Kids). The second section explains some of the factors of cross cultural living that affect them, causing them to be their own subculture. The third section explains how to help your TCKs to make the most of their experience and deal with the challenges.
Misunderstood: The Impact of Growing Up Overseas in the 21st Century by Tanya Crossman
Examining the Third-Culture Kid experience for children of missionaries, diplomats, military personnel and businesspeople, this book offers "a window into how international life can affect the way a child thinks and feels about their world, and how this different perspective may manifest in the way they interact with others." Crossman attempts to help the reader understand TCKs and how their experiences have shaped them. She includes information about helping TCKs through transition and grief, helping them say 'goodbye' well, understanding what they go through during home visits and repatriation, and being aware of tools that can help TCKs strengthen their ability to experience and express their emotions.
Families on the Move by Marion Knell
Knell has produced a very practical book focused on helping parents understand how to help their children navigate the challenges of growing up as a TCK with chapters on building a firm foundation within the family, dealing with transitions, preparing for overseas living, building bridges between cultures, dealing with educational options, living in a non-Western culture, and coping with re-entry. The book closes with a chapter addressing the unique challenges of missionaries.
