This document reports on a materials development project created for volunteer tutors in the English-In-Action (EIA) program of the Bechtel International Center at Stanford University. EIA provides foreign students, visiting scholars, and their spouses with the opportunity to improve their English language skills in an informal, conversational setting. Participants spend about 1 hour per week with a volunteer English-speaking tutor. The document is designed to serve as a guide for new and continuing tutors in the program, providing them with concrete ideas and resources to help carry out their tutorial assignments. The first section contains guidelines to help tutors with preparation, participation in activities, and follow-up. The second section consists of 25 topic chapters, each of which has ideas for vocabulary, discussion, and practice, leading to the student participating in an independent activity involving English.
