Books by PTTW


for universities

This book addresses the value system needed for a society to excel and grow, filling the gap left in most educational systems by teaching the principles that make for successful individuals. The goal of the book is the development of character. The values and principles presented here are not new, but have been transforming lives and societies for generations.


for primary schools

The principles presented in this book are geared to children in primary schools especially fourth and fifth graders. Although the focus is on children in these grades, a teacher can apply the many stories to children of any age. Teachers using this book in the classrooms will be surprised at how quickly their children will respond. When one child begins to take responsibility, others will join in. Don’t be surprised if your schools become better organized, cleaner, and your students better behaved and equipped to become the students you will take great pleasure in teaching.



John Potts and Erik Valenzuela, the authors of this book combined their experience in writing this book. John, an Electrical Engineer, and Erik the pastor of a Spanish speaking church are concerned with the shallowness of many Christians.

John is concerned with the dearth of Christians in business, health care, military, workers, scientists, lawyers and doctors. Erik is less concerned with new converts than he is with making disciples.

Together, they have written this book to show Christians how to live and how to represent their Lord Jesus wherever they are. They do this with stories from the Bible and stories of men and women living great lives in obedience to their calling.

For Teachers

how to use the book in your classroom

If you are a teacher in a primary school, middle school, high school or university, the best way to teach these principles to your students is to focus on just one principle at a time and connect it with some type of project, so that students can truly discover the value of the principle being considered. For example, you could break your class into groups and have them share what the principle means by way of a drama or discussion or you could help them prepare a program for a children’s hospital or orphanage.



“Values and Principles is an extraordinary tool that ought to be implemented in all centers that develop leaders in Latin America.
