Keywords: Mobile-Assisted Language Learning (MALL), reading comprehension, formative assessment INTRODUCTION The rapid advancement of mobile technology has significantly reshaped English language learning practices Mobile-Assisted Language Learning (MALL) offers learners flexibility, accessibility, and interactivity, enabling them to engage in language learning beyond the traditional classroom. Within MALL, mobile-based reading comprehension assessments have emerged as innovative tools for evaluating learnersAo understanding of texts while providing immediate feedback. These assessments have the potential to enhance learner autonomy, promote engagement, and improve performance. However, in EFL contextsAiparticularly at the secondary school levelAithe pedagogical quality, validity, and reliability of such assessments remain Mobile-Assisted Language Learning (MALL) refers to the use of handheld mobile devices, such as smartphones and tablets, to facilitate language learning through applications, multimedia content, and interactive MALL enables learning beyond classroom boundaries, providing flexibility, immediate access to resources, and personalized learning paths (Kukulska-Hulme & Viberg, 2018. Traxler, 2. Recent studies highlight that MALL enhances learner autonomy, motivation, and engagement, especially in reading skill development (Chen et al. , 2021. Noori, 2. In EFL contexts, mobile-based applications offer a valuable platform for integrating assessments into learning, allowing for real-time feedback and continuous performance Reading comprehension involves the ability to construct meaning from written texts by integrating prior knowledge, language skills, and textual information (Grabe & Stoller, 2. In EFL settings, students often face challenges such as limited vocabulary, lack of reading strategies, and insufficient exposure to authentic texts. Mobile applications can address these challenges by offering multimodal resources, interactive tasks, and adaptive difficulty levels that align with learnersAo proficiency (Zhang & Zou, 2. Research indicates that the use of cognitive reading strategiesAisuch as predicting, summarizing, and inferencingAiembedded within mobile applications can significantly improve reading comprehension outcomes (Liu et al. , 2. Formative assessment refers to ongoing evaluation during the learning process to provide feedback that informs and improves student performance (Black & Wiliam, 2. In mobile-based learning environments, formative assessments can be integrated directly into instructional content, allowing learners to immediately apply How to cite this article: Pratiwi. , & Firdaus. Effectiveness of mobile-assisted language learning on EFL studentsAo reading comprehension. Global Expert: Jurnal Bahasa dan Sastra, 13. , 32-36 feedback and adjust their strategies (Shute & Rahimi, 2. Features such as instant scoring, personalized hints, and adaptive task sequencing enhance the effectiveness of formative assessments in EFL reading comprehension (Wang & He, 2. However, poorly designed assessmentsAisuch as those relying solely on repetitive multiplechoice questions without meaningful feedbackAimay fail to foster deeper comprehension (Noori, 2. The integration of MALL, reading comprehension strategies, and formative assessment practices offers a promising approach to enhancing EFL learnersAo reading skills. Mobile applications that embed well-structured formative assessments using cognitive reading strategies can facilitate deeper engagement, improve comprehension, and support autonomous learning. Empirical evidence suggests that when these elements are aligned, learners experience measurable gains in performance and maintain higher motivation levels (Chen et al. Liu et al. , 2. Nevertheless, there remains a need for further investigation into how these assessments influence studentsAo reading performance and how learners perceive their effectiveness in real-world educational Existing studies have shown the positive impact of mobile learning applications on vocabulary acquisition, reading fluency, and learner motivation . Chen et al. , 2021. Noori, 2. While some research has addressed mobile-based reading activities, few have specifically examined the design and effectiveness of reading comprehension assessments embedded in these applications. Moreover, many previous studies relied primarily on self-reported measures, without integrating objective performance data such as pre- and post-test scores. This limits the ability to draw strong conclusions about the actual impact of mobile-based assessments on learnersAo comprehension performance. Despite the growing adoption of MALL, there is limited empirical evidence on the effectiveness of mobilebased reading comprehension assessments that employ cognitive reading strategies and provide meaningful, timely feedback. Additionally, little is known about how studentsAo perceptions of these assessments relate to their actual performance gains. Addressing these gaps will provide valuable insights for educators, app developers, and curriculum designers seeking to optimize mobile-based reading assessments in EFL contexts. This study aims to evaluate the effectiveness of mobile-based reading comprehension assessments in improving EFL studentsAo reading performance and to explore the relationship between studentsAo perceptions of these assessments and their reading comprehension gains. Based on the background and identified gaps, the study addresses the following research questions: Is there any significant difference on EFL studentsAo reading comprehension before and after being taught by using MALL? To what extent do mobile-based reading comprehension assessments improve studentsAo reading comprehension performance in English learning applications? What is the relationship between studentsAo perceptions of mobile-based reading comprehension assessments and their reading comprehension gains? METHODOLOGY This study employed a quantitative quasi-experimental pre-test/post-test design with a correlational component. The quasi-experimental approach was used to measure changes in studentsAo reading comprehension performance before and after the intervention, while the correlational analysis examined the relationship between studentsAo perceptions of mobile-based reading comprehension assessments and their reading score gains. The participants were 120 upper secondary school EFL students from three public senior high schools in South Sumatra. Indonesia. The sample was selected using purposive sampling to ensure that participants had basic digital literacy skills and access to mobile devices. The group consisted of 58 males and 62 females, aged between 16 and 17 years. All participants provided informed consent, and the study was approved by the institutional ethics In this study, two primary instruments were used: Reading Comprehension Test Ae A 25-item multiple-choice test adapted from nationally standardized English examinations and aligned with the cognitive reading strategies framework (Grabe & Stoller. The test was piloted with a comparable group of students, yielding a CronbachAos alpha reliability coefficient of 0. Perception Questionnaire Ae A 20-item questionnaire adapted from established reading assessment frameworks (Chen et al. , 2021. Noori, 2. , measuring five dimensions: usability, content quality, feedback mechanisms, engagement, and learning support. Items were rated on a 5-point Likert scale. The questionnaireAos reliability was confirmed with a CronbachAos alpha of 0. The study was conducted over two weeks. In Week 1, participants took the pre-test to measure their baseline reading comprehension performance. They were then introduced to two mobile learning applications (BBC Learning English and English Reading Tes. and instructed to complete the assigned reading comprehension Global Expert: Jurnal Bahasa dan Sastra Vol. No. July 2025 activities integrated within the apps. The apps included interactive tasks and immediate feedback features. Week 2, after completing the intervention period, participants took the post-test and filled out the perception Quantitative data from the pre- and post-tests were analyzed using a paired sample t-test to determine whether there was a statistically significant difference in reading comprehension scores before and after the Pearson product-moment correlation was used to examine the relationship between studentsAo perceptions of the mobile-based assessments and their reading score gains. Statistical analyses were conducted using SPSS version 25, with significance set at p < 0. FINDINGS AND INTERPRETATION Pre-Test and Post-Test Reading Comprehension Scores The results of the paired sample t-test indicated a statistically significant improvement in studentsAo reading comprehension scores after the intervention. Table 1. Paired Sample t-Test Results for Reading Comprehension Scores Test Condition Pre-Test Post-Test Mean p-value CohenAos d < 0. The mean reading comprehension score increased from 64. 75 (SD = 7. in the pre-test to 72. 13 (SD = 7. in the post-test. The paired sample t-test showed that this difference was statistically significant . = 13. 427, p < . , with a moderate-to-large effect size (CohenAos d = 0. , indicating substantial practical significance. Figure 1. Pre-Test vs. Post-Test Mean Scores This visual clearly shows an upward shift in reading comprehension performance following the use of mobilebased assessments. StudentsAo Perceptions of Mobile-Based Reading Comprehension Assessments Descriptive analysis of the perception questionnaire revealed that students expressed highly positive attitudes toward the mobile-based reading comprehension assessments. Table 2. Mean Perception Scores by Dimension Dimension Usability Content Quality Feedback Mechanisms Engagement Level Learning Support Mean On a five-point Likert scale. Usability (M = 4. and Engagement Level (M = 4. received the highest ratings, indicating that students found the applications easy to navigate and engaging. Feedback Mechanisms received the lowest rating (M = 4. but was still above the AuAgreeAy level, suggesting room for improvement in providing more comprehensive and explanatory feedback. Global Expert: Jurnal Bahasa dan Sastra Vol. No. July 2025 Figure 2. StudentsAo Perceptions by Dimension Correlation Between StudentsAo Perceptions and Reading Score Gains Pearson product-moment correlation analysis showed a moderate positive correlation . = 0. 46, p < 0. between studentsAo overall perception scores and their reading comprehension gains . ost-test minus pre-test This indicates that students who reported more positive perceptions of the mobile-based assessments tended to achieve higher improvements in their reading performance. The findings of this study provide empirical evidence that mobile-based reading comprehension assessments can significantly enhance EFL studentsAo reading performance when designed with pedagogically sound principles. The statistically significant improvement in post-test scores, with a moderate-to-large effect size (CohenAos d = . , suggests that the integration of interactive assessment features, authentic materials, and immediate feedback in mobile applications positively influences studentsAo reading comprehension. These results align with previous studies that have demonstrated the benefits of Mobile-Assisted Language Learning (MALL) for skill development in EFL contexts. Chen et al. and Liu et al. found that mobile applications incorporating cognitive reading strategiesAisuch as prediction, summarization, and inferencingAican foster deeper engagement and comprehension. Similarly. Wang and He . reported that formative assessment embedded within mobile learning environments enhances studentsAo motivation and learning outcomes, particularly when feedback is timely and constructive. The high perception scores for Usability and Engagement Level indicate that user-friendly design and interactive elements are crucial for sustaining learner interest. This is consistent with NooriAos . conclusion that ease of navigation and engaging task formats significantly influence learnersAo willingness to persist in completing reading tasks. In contrast, the relatively lower rating for Feedback Mechanisms, although still positive, highlights an area for improvement. As Shute and Rahimi . emphasized, feedback that is specific, explanatory, and actionable is more likely to result in meaningful learning gains compared to generic or purely evaluative comments. The moderate positive correlation between studentsAo perceptions and their reading score gains . = 0. 46, p < . suggests that attitudes toward the assessment features are not only reflective of user satisfaction but also linked to measurable learning outcomes. This relationship supports the self-determination theory (Deci & Ryan, 2. , which posits that learner motivation, autonomy, and engagement can directly impact performance. Students who viewed the assessments as useful, relevant, and supportive of their learning were more likely to invest cognitive effort, thereby improving their reading comprehension. Implications for EFL Practice These findings have several implications for EFL teachers, curriculum designers, and application developers: Pedagogically Aligned Design Ae Mobile-based reading comprehension assessments should be built on evidence-based reading strategies and aligned with curricular goals. Interactive and Adaptive Features Ae Engagement can be enhanced through interactive tasks, gamified elements with educational value, and adaptive difficulty levels that respond to learner performance. High-Quality Feedback Ae Feedback should go beyond indicating correct/incorrect responses. it should explain reasoning, suggest improvement strategies, and encourage metacognitive reflection. Teacher Mediation Ae While mobile applications can facilitate autonomous learning, teacher guidance remains essential to integrate these tools effectively into classroom instruction and support learners in developing transferable reading strategies. CONCLUSION Global Expert: Jurnal Bahasa dan Sastra Vol. No. July 2025 This study aimed to evaluate the effectiveness of mobile-based reading comprehension assessments in improving EFL studentsAo reading performance and to examine the relationship between studentsAo perceptions of these assessments and their reading gains. Using a quantitative quasi-experimental pre-test/post-test design with a correlational component, data were collected from 120 upper secondary school students in South Sumatra. Indonesia. Instruments included a standardized 25-item reading comprehension test and a validated 20-item perception questionnaire. The findings indicated a statistically significant improvement in reading comprehension scores after the intervention, with a moderate-to-large effect size. Students expressed highly positive perceptions toward the mobile-based assessments, particularly in usability and engagement, while feedback mechanisms received slightly lower ratings. A moderate positive correlation was found between studentsAo perceptions and their reading score gains, suggesting that positive attitudes toward assessment design can translate into measurable learning Practical Recommendations: Design Improvements Ae Mobile-based reading assessments should integrate cognitive reading strategies, authentic materials, and high-quality feedback to maximize learning outcomes. Curriculum Alignment Ae Applications should be aligned with EFL curricular goals to ensure relevance and transferability of skills. Teacher Involvement Ae Educators should mediate the use of mobile-based assessments to guide learners in applying strategies effectively. REFERENCES
