The Implementation of Metacognitive Strategy in Writing Sentences at Junior High School 22 Jakarta

Abstract

This research aims to investigate the implementation of metacognitive strategy in students’ sentence writing at the ninth-grade students of Junior High School 22 Jakarta in the academic year 2022 – 2023. It was pre-experimental research in which the students were given pre-test, treatment, and post-test. The sample of the study was 30 students from one class. To know the implementation of metacognitive strategy, t-test formula was used to prove the effectiveness of metacognitive strategy in students’ sentence writing. To test research hypothesis, normality test and paired sample t-test were used. The calculation of the normality test in the pre-test was 0.68 and the normality in the post-test was 0.65.  Based on the calculation, the data were normally distributed. Then, the calculation of t-test was 5.83 greater than t-table 2.045. It can be concluded that the null hypothesis is rejected while the alternative hypothesis is accepted. It means that the implementation of metacognitive strategy is effective in sentence writing performance for students of Junior High School 22 Jakarta in the academic year 2022/2023. It is suggested that metacognitive strategy is useful for improving students’ competence in writing sentences.
