THE CONTRIBUTION OF SENTENCE STRUCTURE COMPETENCE AND SELFEFFICACY TO WRITING ABILITY

Abstract

The aim of this study is to find out (1) the contribution of sentence structure competence to writing ability; (2) the contribution of self-efficacy to writing ability; (3) the contribution of sentence structure competence and self-efficacy to writing ability. The method of this study is correlation method. To fulfill the aim of study, 30 students out of 512 of senior high school students were taken as sample by cluster random sampling and random sampling. The instruments used to collect the data are test and questionnaire. The data obtained are analyzed by Pearson Product Moment Formula and Multiple Regression and Correlation. The result of this study indicates that sentence structure competence and selfefficacy give significant positive contribution to writing ability; both partially and simultaneously. It means sentence structure competence and self-efficacy can be used to predict writing ability. The result also indicates self-efficacy has greater contribution than sentence structure competence. Therefore, self-efficacy should be paid more attention.
