The purpose of this study was to develop vocabulary materials to aid non-native English speakers, specifically Russian speaking test-takers, in their preparation for the mathematical sections of the General Record Examination (GRE) and the Graduate Management Admission Test (GMAT) in terms of English mathematical vocabulary. GRE and GMAT preparation materials and practice tests published by the Educational Testing Service, Kaplan, and Barron's were analyzed with the help of computer software. This data was then used to determine which key words to include in the vocabulary tool, which is now available on Quizlet (www.quizlet.com). The developed materials were further proofread by competent mathematics and English language professionals and assessed with the help of a questionnaire administered to them. The rationale of the materials development and the procedures used for the process are described in detail in this thesis project.
