The Vocabulary Profile of The English Textbook Used in The 10TH Grade of Satya Wacana Christian Senior High School Salatiga

Abstract

Vocabulary is the most important role in learning a target language. The students who want to learn a language should understand the vocabulary as the beginning step. However, students often face difficulties in reading material or textbook because of the limitation of vocabulary knowledge. To minimize the students’ difficulties, the teachers need to profile the material or textbook which is used so that they can determine appropriate vocabulary for the students. Since vocabulary profile is needed, the research was conducted to profile the vocabulary in the students’ textbook of the 10th grade of Satya Wacana Christian High School, which shows negative vocabulary in the textbook, and to show the number of words (token) recycling index of the textbook. This study used a descriptive method. There was a selected textbook with fifteen chapters on it as a sample of this study. The analysis used an electronic tool name the Compleat Lexical Tutor which can be accessed at lextutor.ca. The findings showed the cumulative percentage of the overall vocabulary profile in the textbook from K-1, K-2, and AWL words (89.17%). The findings also showed the negative vocabulary profile (words not found) based on the New General Service List (NGSL) as much as 6.02% for K-1, 37.53% for K-2, and 43.23% for K-3.
