distinguishing advanced readers from novice readers in both L1 and L2 settings The explicit and intensive instruction of discourse structure awareness could be conducted via the use of discourse structure graphic organizers (DSGO) This thesis attempts to verify the effectiveness of discourse structure awareness and the use of DSGO in improving EFL learners’ reading comprehension A total of 48 college-level Vietnamese learners participated in this study under the membership of two different groups: Experimental Group and Comparison Group The Experimental Group received explicit training on how to use DSGOs to represent and organize a specific discourse structure, while the Comparison Group strictly followed the syllabus outlined by their traditional course books A Toefl iBT (Test of English as a Foreign Language) reading comprehension test, a graphic organizer test, and a recall protocol test were administered to participants before and after the treatment The results showed DSGO instruction significantly improved students’ performance on a number of measures: general reading comprehension ability, discourse comprehension, and their recall of idea units Moreover, the data obtained from the questionnaire indicated that participants believed that DSGO instruction is beneficial in helping them relieving the cognitive strain when reading According to most of the respondents, DSGO instruction had a positive effect on their motivation and their future reading habits The main research questions about the effects of DSGO instruction, therefore, were answered with satisfactory results iv TABLE OF CONTENTS Statement of Authorship………………………………………………………………… i Retention and use of the thesis……………………………………………………………ii Acknowledgement……………………………………………………………………… iii
