Abstract Vocabulary mastery is one of the key factors in improving English language skills, particularly for university students who are learning a foreign language at the tertiary level. However, based on observations of second-semester students in the Agribusiness Management Study Program at Politeknik Negeri Lampung, it was found that limited vocabulary remains a major obstacle to their ability to construct varied sentences To address this issue, this study implemented the Memrise application as a digital-based medium for vocabulary learning. Memrise was chosen due to its interactive features, which enable students to learn and retain new vocabulary more effectively through a gamification approach and spaced repetition. This study employed a quasiexperimental method with a pre-test and post-test design on a group of students who received treatment using Memrise. The results revealed that the use of Memrise had a significant positive effect on studentsAo vocabulary improvement. After the treatment, students were able to use a wider variety of vocabulary in constructing sentences, which directly contributed to greater complexity and diversity in the sentence structures they These findings indicate that the integration of digital technology into language learning can serve as an effective strategy to enhance studentsAo competence, particularly in enriching vocabulary that supports their English communication skills.

Quasi-Experimental Study INTRODUCTION Vocabulary mastery plays a crucial role in the process of language learning, particularly English. Without adequate vocabulary mastery, an individualAos ability to comprehend texts, speak, write, and listen becomes severely limited (Baker et al. , 2. the context of higher education, studentsAo ability to master English vocabulary not only affects their academic performance but also serves as an essential asset in facing an increasingly globalized workforce (Latif, 2. However, in reality, many students still struggle to develop their vocabulary mastery. One of the consequences of this limitation is their difficulty in constructing varied and complex sentences, both in oral and written communication (Lailiyah & Suryati, 2. This phenomenon is clearly observed from studentsAo tendency to repeatedly use the same simple vocabulary when asked to construct sentences in English. The inability to master and utilize a variety of vocabulary not only limits their expression but also reflects a lack of understanding of word meanings and contextual usage (Laufer, 2. Such limitations are often caused by insufficient exposure to effective vocabulary learning practices and a lack of motivation to engage in independent learning outside the classroom (Nation, 2013. Sundqvist & Sylvyn, 2. Kognisi: Jurnal Ilmu Keguruan ISSN . : 2987-0240 Volume 3 Nomor 1 Tahun 2025 https://afeksi. id/journal3/index. php/kognisi/index Along with technological advancements. English language learning now offers a wider range of methods and media. One of the rapidly growing media is digital-based learning applications, such as Memrise. This application is designed to assist users in memorizing vocabulary through the use of spaced repetition, enhanced with gamification elements. These features create an interactive and enjoyable learning experience, thereby increasing studentsAo motivation to learn (Godwin-Jones, 2. With its structured approach. Memrise enables users to acquire new vocabulary in a relatively short period while also retaining it in longterm memory (Li & Hafner, 2022. Loewen et al. , 2. The use of technology in language learning, particularly applications such as Memrise, has been widely studied, one of which is a study conducted by Auczak . The research demonstrated that this application is not only effective in improving vocabulary acquisition but also has a positive impact on studentsAo learning motivation. However, the implementation of this technology in Indonesia, particularly in the context of higher education, still requires further investigation. The effectiveness of this application in helping students improve their vocabulary mastery while simultaneously developing their ability to construct varied sentences has not yet been extensively explored (Pratama & Yulianto, 2020. Shadiev et al. , 2. In this study, the main focus is to evaluate the effectiveness of the Memrise application in improving studentsAo English vocabulary mastery. In addition, this study also aims to examine the extent to which the improvement of vocabulary mastery impacts studentsAo ability to construct more varied sentences. The study is based on the assumption that the use of innovative learning technologies, such as Memrise, can serve as an effective solution to address vocabulary learning challenges among university students (GodwinJones, 2018. Li & Hafner, 2022. Pratama & Yulianto, 2. To test this assumption, the study adopted a mixed-method approach combining both quantitative and qualitative designs, specifically classroom action research. The research was conducted on a population of university students with a sample of 30 participants selected randomly. This study not only measured studentsAo vocabulary mastery outcomes after using Memrise but also analyzed their experiences during the use of the application. Through this approach, the findings are expected to provide a comprehensive overview of the benefits of using digital technology in English language learning (Creswell & Creswell. Mertler, 2019. Fraenkel et al. , 2. This study is also grounded in theoretical foundations regarding the use of technology in language learning, as explained by Chapelle . in her book Computer Applications in Second Language Acquisition. According to Chapelle, technology provides opportunities to enhance the efficiency of language learning by offering adaptive and interactive materials. In addition, the theory of spaced repetition applied in Memrise, as described by Cepeda et al. , serves as the basis for the applicationAos approach in helping users retain vocabulary in long-term memory. By integrating digital approaches and technological innovations into language learning, this study not only contributes to the development of more effective teaching methods but also provides practical benefits for both instructors and students. The use of Kognisi: Jurnal Ilmu Keguruan ISSN . : 2987-0240 Volume 3 Nomor 1 Tahun 2025 https://afeksi. id/journal3/index. php/kognisi/index applications such as Memrise is expected to serve as a learning model that can be widely applied in higher education contexts, particularly to enhance studentsAo English vocabulary mastery (Beatty, 2013. Stockwell & Hubbard, 2013. Kukulska-Hulme & Shield, 2. METHODS This study employs a classroom action research design. To ensure the smooth implementation of the study, certain procedures related to the research problem are required in the form of research preparation. The course of the study can be described as follows. Figure 1. Classroom Action Research Design The population in this study consisted of all second-semester students of the Agribusiness Management Study Program, totaling 30 students. The sample used was equal to the population, in accordance with the opinion of Arikunto . , who stated that if the population is fewer than 100, it is preferable to include the entire population as the sample. Data were collected through tests and observations. The tests were conducted in two stages, namely a pre-test to measure studentsAo initial ability and a post-test to evaluate the effectiveness of the Memrise application in improving studentsAo English vocabulary mastery. Observations were carried out during the research process to examine the alignment between the planned actions and their implementation. Data analysis included both quantitative and qualitative data. Quantitative data were analyzed descriptively by calculating the mean score and the percentage of learning mastery based on studentsAo level of comprehension. Students were considered to have achieved mastery if they reached a minimum comprehension level of 70% (Arikunto, 2010. Creswell & Creswell, 2. Kognisi: Jurnal Ilmu Keguruan ISSN . : 2987-0240 Volume 3 Nomor 1 Tahun 2025 https://afeksi. id/journal3/index. php/kognisi/index This study employed a classroom action research method consisting of two cycles. In each cycle, planning, implementation, observation, and reflection were carried out. The first cycle included lesson planning, learning activities with teacher guidance, and observation of studentsAo interest and skills. The reflection results from the first cycle were used to make improvements for the second cycle. The second cycle followed the same stages, aiming to further optimize the learning process. The final reflection served as the basis for evaluating the effectiveness of the teaching method applied (Kemmis & McTaggart, 1988. Mertler. RESULTS & DISCUSSION Result This classroom action research was conducted to evaluate the effectiveness of the Memrise application in improving studentsAo English vocabulary mastery. The study was carried out in two cycles, each consisting of the stages of planning, implementation, observation, and reflection. In Cycle I, the planning stage began with English language course activities. The implementation was conducted in two sessions: the first session focused on applying conventional methods by analyzing English vocabulary, while the second session was dedicated to an evaluation consisting of 10 multiple-choice questions. During the learning process, the lecturer formed groups, demonstrated the application, and guided students in discussions as well as in presenting their results. However, observations revealed that student activity was not yet optimal, with relatively low engagement in paying attention to the lecturerAos explanations, writing down discussion outcomes, and responding to other groupsAo The reflection on Cycle I involved collaborative evaluation between the lecturer and the researcher to identify obstacles, such as the lack of student participation in discussions and difficulties in understanding English vocabulary. Based on these findings, improvements were planned for Cycle II to increase student engagement and enhance overall learning Table 1.

The lecturer began the lesson with attendance and provided an overview reflection of the Cycle I evaluation results, emphasizing that the scores obtained were still unsatisfactory and that students were expected to study more diligently. After conducting a question-and-answer session as an apperception activity, students returned to their groups to analyze English vocabulary using Memrise. Each group recorded the results of their discussion and presented them through a representative, followed by reinforcement from the lecturer. Observations indicated an increase in student activity compared to Cycle I. StudentsAo attentiveness to the lecturerAos explanation improved, although some were still less focused. Participation in writing discussion results also showed improvement, even though in each group there were still one or two students who were less active. In addition, nearly all students began to engage in responding to other groupsAo presentations, which demonstrated progress in interactive English vocabulary learning. The reflection on Cycle II revealed that students experienced significant Observation data and test results showed that the students had met the success Furthermore, the use of Memrise to enhance studentsAo English vocabulary mastery proved to be highly effective, as evidenced by their improved activity compared to Cycle I. Thus. Cycle II can be considered successful in enhancing studentsAo mastery of English Table 2.

Based on the findings, before the intervention, the average pre-test score was 60. 33, with a learning mastery rate of 50%. After the second cycle of intervention, in which learning activities were combined with the use of Memrise, the studentsAo average test score increased to 80, with a mastery rate of 90%. These results clearly demonstrate that the application significantly enhanced studentsAo vocabulary The integration of Memrise not only improved vocabulary acquisition but also increased student engagement and motivation. Students became more enthusiastic and focused during the learning process. The lecturerAos open, attentive, and guiding attitude further encouraged students to stay engaged. Additionally, the provision of praise from the lecturer helped students feel more confident, active, and willing to ask questions. Memrise also fostered a collaborative learning environment by encouraging mutual support among students within their groups, aligning with research that highlights the social and motivational benefits of gamified learning environments (Li & Hafner, 2022. Loewen et al. , 2. Furthermore. Memrise is designed in such a way that students can analyze English vocabulary and transform it into sentences based on the content within the application. This approach places greater emphasis on contextual analysis, which is considered essential in promoting deeper understanding and long-term retention of vocabulary (Nation, 2013. Godwin-Jones, 2. The table 3 describes studentsAo learning outcomes in Cycle I and Cycle II. Table 3. Average Results of Cycle I and Cycle II Description Average Score Mastery Level Cycle I 60,33 Cycle II 80,00 RESULTS The implementation of the Memrise application has been proven effective in enhancing studentsAo mastery of English vocabulary. In the first cycle, studentsAo participation was relatively low, as reflected in their limited activeness in answering questions, recording discussion results, and responding to other groupsAo presentations. After improvements were made in the second cycle, students demonstrated a significant increase in engagement, better understanding of the material, and higher average learning scores. The findings indicate that Memrise not only improves vocabulary acquisition but also fosters active participation, critical thinking, and collaborative learning among students. Therefore. Memrise can serve as an effective alternative medium in vocabulary learning to create a more engaging and interactive learning environment in higher education. REFERENCES
