The purpose of this classroom action research project is to find out how well seventh-grade female students at Mutiara Qur'an Islamic Boarding School in Wonogiri learn Arabic with the use of the audiolingual approach. By emphasizing active listening and pronunciation, the audiolingual approach makes it easier for students to comprehend and communicate in Arabic. Twelve female seventh-graders at Mutiara Qur'an Islamic Boarding School participated in the researcher's qualitative study in order to gather the research findings. The study was conducted in two cycles to enhance Arabic language learning. Planning, action, observation, and reflection are the four components of each cycle in the Kurt Lewin model. Tests, observations, and interviews were the methods utilized to get the data. The proportion of learning mastery and descriptive analysis were used to examine the collected data. The study's findings show that the audiolingual approach is successful in raising female students' Arabic language learning outcomes.

Vocabulary acquisition is fundamental to language proficiency, yet retention remains a persistent cognitive challenge for students. Conventional rote-learning strategies often fail to facilitate long-term recall. This study examines the effectiveness of the keyword technique in improving students’ vocabulary mastery. Employing a quantitative quasi-experimental design, the research involved 48 students selected through cluster random sampling. The samples were separated into two groups: an experimental group of 26 students (taught by using the keyword technique) and a control group of 22 students (taught by using conventional strategy). Data were collected using a validated multiple-choice vocabulary test administered before and after the treatment. This result validates a notable difference in outcomes where the experimental group demonstrated better performance; consequently, the alternative hypothesis (Ha) is accepted, leading to the rejection of the null hypothesis (H0). These findings confirm that the Keyword Technique significantly enhances vocabulary mastery by leveraging acoustic and imagery associations. Consequently, this strategy is recommended to foster more effective vocabulary retention.

This thesis discusses efforts to increase students’ interest in learning Mathematics through the use of concrete media among third-grade students at SDN 110/1 Tenam. The purpose of the study is to improve students’ interest in learning Mathematics by using concrete media with these third-grade students. The results of the study show an increase in learning activities that indicate student interest during Cycle I and Cycle II. In Cycle I, all student learning activities were still at percentages below 70%, with ratings categorized as poor and adequate. Meanwhile, in Cycle II, the increase in student learning activities was shown by all activities reaching percentages above 74%, which means they exceeded the predetermined Learning Objectives Achievement Criteria (KKTP) and were rated good and very good. In addition, improved learning outcomes, as evidence of increased student interest, also showed a significant rise. In Cycle I, students’ learning outcomes did not meet the Learning Objectives Achievement Criteria (KKTP), with a class average of 68.9%, whereas in Cycle II, overall class mastery reached 82.3%. This improvement in learning outcomes indicates that students showed fairly good interest when learning with concrete media.

This study aimed to improve the English learning outcomes of 9B grade students at UPT SMP Negeri 28 Medan in the 2024/2025 academic year through the implementation of the Student Teams Achievement Division (STAD) method. This research applied a Classroom Action Research (CAR) approach conducted in two cycles. Data were collected through learning outcome tests administered in the pre-cycle, Cycle I, and Cycle II. The results showed that the STAD method improved students’ average scores from 67.125 in the pre-cycle to 73.75 in Cycle I, and further to 78.81 in Cycle II. The percentage of students achieving the Minimum Mastery Criteria (KKM) increased from 25% to 78.1%. The Wilcoxon test indicated a statistically significant difference in learning outcomes before and after the intervention. The findings suggest that the STAD method is an effective cooperative learning strategy to enhance students’ English performance and foster collaborative classroom skills. Nevertheless, teachers must consider individual differences within teams to ensure equitable learning experiences for all students.

This study explores the application of English education focused on the topic of body parts, utilising musical resources as a supplementary tool for students in class IV-D at SDN 060871 Medan Timur. The research method used is quantitative with an experimental design through pre-test and post-test to determine the effectiveness of song media in improving English vocabulary mastery. The research results showed that before the application of song media, student learning outcomes were in the poor category with a completeness level of 54.54%. After implementing song media, there was an increase in student learning outcomes until they reached a completion level of 90.90%. This demonstrates that utilising music can aid learners in grasping and retaining English vocabulary with greater efficiency. Apart from that, the results of the confirmation questionnaire also showed that the majority of students gave positive responses to the application of song media in learning English. Therefore, song media can be used as an alternative learning method that is interesting and effective in improving student learning outcomes in mastering English vocabulary.

This study analyzes the effectiveness of using Word Wall as a learning medium to enhance student’s understanding in English language learning, particularly on the topic of parts of the body. A Word Wall is a visual medium consisting of a collection of specific words displayed on a large wall or board in the classroom, helping students recognize, memorize, and understand vocabulary interactively. This research employs a descriptive qualitative method with a literature review approach, collecting and analyzing various relevant sources. The results indicate that Word Walls are effective in improving student’s vocabulary mastery, which is a crucial component of English language learning. Students using this medium showed increased activity, enthusiasm, and confidence in practicing speaking. Additionally, post-test scores were consistently higher than  pre-test scores, indicating significant improvement in understanding. This medium also enhanced students' learning outcomes, with the percentage of learning completeness increasing from the first to the final cycle in several classroom action research studies. Thus, Word Walls prove to be an effective and engaging learning medium for improving students' understanding and learning outcomes in English language education.
