This study aims to use a question-answer relationship strategy to improve reading comprehension skills for grade 10 students at Dong Hy High School. During the research, 20 grade 10th students participated in the survey questionnaire and 20 students participated in the experiment. There are 20 students who took the pre-test to check their level and then were divided into two groups: the experimental group and the control group, and each group had exactly 10 learners. Members of the control group did reading comprehension exercises. They also performed both before and after tests to compare the effects of using the Question-Answer Strategy on the experimental group. While the experimental group had the same level as the control group after pre-test. They were asked to read short or medium passages applying each question type in the strategy once a week. The researchers also created groups on Facebook to exchange and sent practice links to the exercises and tests to the participants so that the researchers could review and track their learning and progress their sets. The researchers used questionnaires and a reading comprehension test as the two main tools, and SPSS 20 was used to analyze the data. The findings of this study led to several conclusions. The question-answer relationship strategy had a positive impact on students' reading comprehension. Furthermore, all students participating in the study expressed satisfaction and enthusiasm during the study period.
