English classroom language is very essential for teaching and learning activities. The electronic book or e-book is one of the various tools to enhance teachers’ English communication in class. This study aimed to develop Mathematics Teachers’ English classroom language usage by using electronic book, and to study Mathematics Teachers’ opinions toward electronic book. The participants consisted of 3 Mathematics teachers at Demonstration School, Suan Sunandha Rajabhat University. The instruments were the electronic book, the supervision forms, the questionnaires and the interview. The data were analyzed by the applications of mean, standard deviation, conclusion and description.
The study’s findings revealed that English classroom language usage of Mathematics teachers was in a high level (mean = 3.73, S.D. = 0.59). The highest average was “Mathematics teachers use English classroom language in class” (mean = 4.33, S.D. = 0.57). For Mathematics Teachers’ opinions toward electronic book, the result showed that Mathematics Teachers’ opinions was in a high level (mean = 4.20, S.D. = 0.57). When considering the part of content, it revealed that, “the contents are accurate and appropriate for the students’ (mean = 4.67, S.D. = 0.58). For the design, it showed that “the pictures, colors, font sizes are appropriate and interesting” (mean = 4.00, S.D. = 0.00). For the benefit, it illustrated that “the electronic book is convenient to use anywhere or anytime and Mathematics teachers are able to adapt the sentences from electronic book to be as a model for communication” (mean = 4.67, S.D. = 0.58). For Mathematics teachers’ opinions from the interviews, it revealed that the electronic book benefits the teachers who do not have English basic knowledge, it enhances the teachers’ self-confidence in English communication, it’s very convenient to use. However, the sounds are too fast and there are not various sentences in the electronic book.
