The purpose of this study is to investigate the effect of using a blended learning method on ninth grade students' achievements in English and their motivation towards learning it. The sample consisted of 100 female students selected purposefully and distributed into two groups: experimental and control. The experimental group studied English through a computerized program in the traditional method, while the control group was taught by the traditional method only. The results revealed statistically significant differences between the two groups in favor of the experimental group both in the achievement and the motivation towards learning English. The researchers recommended using computerized teaching in addition to the traditional method due to the positive results shown by the current study. In addition, they recommended conducting studies that measure the effect of blended learning on some aspects related to English language such as: vocabulary, spelling, pronunciation, or any other aspects.
