LEVERAGING THE ACTIVITY OF WATCHING VIDEO VLOGS: ITS EFFECTS ON STUDENTS' VOCABULARY MASTERY GRADE VII

Abstract

Previous studies have shown that English as a foreign language (henceforth, EFL) students learned English through watching videos. However, its effects on first time EFL students’ vocabulary mastery remains unclear. Therefore, this research was conducted to determine the effect of watching video blogs (henceforth, vlogs) on EFL students’ vocabulary mastery. This research employed a quantitative approach. Particularly, this study employed quasi-experimental research using a posttest-only control group design. The research was conducted at a junior high school in Indonesia. The experimental group was taught using vlogs, and the control group used conventional strategies. The sample was selected using an intact group sampling technique. The total population of this study was 117 students, and the sample was 61 students. Data was collected through a post-test through a multiple-choice test given to students. The data were analyzed using the Mann Whitney U Test in the SPSS 25.0 program. The Mann-Whitney U Test for independent samples shows a significant difference in students' vocabulary understanding between the experimental and control classes where the significancy value was smaller than 0.05. The learning outcomes of the experimental class were higher than the control class (Mexp=62.34; Mcon=47.24). Based on these results, there is a significant influence on EFL student's vocabulary mastery.
