Abstract
This study aimed at evaluating the General English textbook currently in use at Payame Noor University (PNU) of Iran. In fact, it investigated the differences between students majoring in humanities and students majoring in science and engineering in terms of their attitudes and achievement after taking the corresponding course and studying the General English textbook for one semester. The study was conducted in two stages: administering attitude questionnaires, and comparing students’ grades at final examination of the general English course. About 150 students took part in the questionnaire including 94 students majoring in humanities and 56 ones majoring in science and engineering. Additionally, the final exam grades of 520 students, 260 from the faculty of science and 260 from the faculty of humanities, were compared in order to find any differences in their achievement in English. The results demonstrated that the textbook falls short of students’ expectations. It was also revealed that while students majoring in humanities showed more positive attitudes towards the textbook, students majoring in science and engineering achieved higher grades in the general English final exam at PNU.
