To fulfill the purpose of the study, a sample of 110 fourth-year student-teachers; 86 females & 24 male, of the English Department, in the Faculty of Education at Hodeidah University, was selected. They enrolled in the four-year B.Ed. course. The Big Five Inventory (BFI) originally developed by John & Srivastava (1999) with little modification was distributed among the selected subjects. This inventory comprised of forty-four statements about the big five personality traits that are Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness. Collected data was analyzed by using simple descriptive and inferential statistical techniques such as mean, Pearson correlation, t-test and f-test. It was found that there is a relationship between the pre-service teachers' performance in Practicums I&II and their personality traits so pre-service teachers' personality DO influence their performance of teaching English. Also, pre-service teachers' personality traits of Extraversion, Agreeableness, and Conscientiousness are nearly same, so no significant difference found among male and females on these three traits. However, significant difference exists among the females and males on the trait of Neuroticism as female student-teacher score higher than males on this trait. Moreover, both male and female pre-service teachers have quite good level of Extraversion and Agreeableness, and similar reasonable level of Conscientiousness and Neuroticism but their level of Openness is a very low. It is recommended that Teacher Personality Development should be a part of teacher education programs and suggest some strategies for development of pre-service teachers’ personality.

Introduction Teaching and learning have been of great importance in all educational settings. Lately, the introduction of the different modern methods of teaching, the paramount role of psychology in education, and the shocking fact that some of the EFL students are reluctant to get involved in the language learning process, have turned the attention of educationists and language specialists into a highly effective issue to identify the probable relation of teachers’ personality and their teaching performance in the learning settings which is of course of great value for both teachers and learners. Also, it is quite clear that some teachers are more effective than others (Atteberry, Loeb & Wyckoff 2013), yet the source of such differences is largely unknown. For this reason, scholars of various disciplines are trying to identify the factors that characterize effective teachers and make differences clear in teachers' performance. Personality may be seen as the dynamic organization of those attributes and characteristic patterns of behavior that are solely specific to the individual (Callahan, 1996). Some social psychologists illustrate that personality is completely a matter of social awareness - which is pointless to discuss about one's personality separated from the individuals who interacts with him, get impersonation about him and use trait terms in uncovering him (Holt, 1971).
