Abstract

• The primary purpose of this study was to investigate the personality styles of Grade 10 students and its correlation with their learning gains. A total of 712 Grade 10 students from Yangon and Bago regions were selected by random sampling technique. The Personality Style Questionnaire and Students Learning Gain Questionnaire were used as the research instruments. According to the survey data, Grade 10 students in this study could be classified into three groups; extrovert personality style (17.84%), introvert personality style (16.43%) and ambivert personality style (65.73%). T-test results showed that there was no statistical difference between personality styles of students by gender. Students in Bago are more extrovert than those in Yangon. Comparing students’ learning gains, male students gained better in science when comparing female students. Students in Yangon attained higher scores in science subjects than students in Bago. Concerning the relationship between the personality styles and learning gains, the statistically significant positive relationship between the variables was found. Finally, the regression analysis was conducted in order to predict the Grade 10 students’ learning gains by their personality styles and socio-economic status. The results revealed that father’s education level and mother’s profession were the predictors of students’ learning gains for extrovert personality style, mother’s education level and father’s profession were the predictors of students’ learning gains for ambivert personality style while father’s profession and mother’s education level were the predictors of students’ learning gains for introvert personality style.
