Abstract

English teacher’s personality competency in improving students’ English language skills at Unggul Cut Nyak Dhien High School, Langsa City, is quite good. However, although the teacher’s personality is good, namely attitude and learning methods, it still needs to be improved in terms of using innovative learning media according to current developments because the teacher’s attitude and personality greatly influence students’ interest in learning. The method used in this research is descriptive qualitative. Data collection techniques use observation, interviews, and documentation, while data analysis uses Miles and Huberman’s theory through data reduction, data presentation, and data conclusions. The research results found that the personality competence of English teachers is very good, thereby increasing students’ competence in English; this can be seen through teacher discipline, good communication with students, fellow teachers, and the surrounding environment, and carrying out their duties as teachers well. The hope is that the results of this research can be used as a reading reference or increase knowledge.

The use of conventional and unvaried learning media causes students to be unenthusiastic and will affect student learning outcomes. This research aims to determine the influence of Wordwall learning media on student learning outcomes on the topic of changes in natural appearance. This research method is a quantitative method. Sampling used a purposive sampling technique with a total sample of 41 students at SD Negeri Bukit Tiga for the 2023/2024 academic year, namely 21 VA students in the experimental class and 20 VB students in the control class. Data was collected using objective test questions to measure learning outcomes on changes in natural appearance. The research results showed that there was an increase in student learning outcomes after learning using Wordwall with student learning outcomes based on the average posttest score for the experimental class of 85.71 and the control class of 73.75. As for the results of hypothesis testing using the Mann-Whitney test, there is a Sig (2-tailed) result of 0.003. This Sig (2-tailed) value is < α (0.05). This means that there is a significant difference in posttest scores between the experimental class and the control class. It can be concluded that there is an influence of the Wordwall learning media on student learning outcomes in the periodic system of elements material.
