Abstract

English speaking skill is essential yet challenging for EFL learners due to linguistic barriers and psychological constraints. This study aims to empirically investigate the effectiveness of the Stimuler Application as a learning medium in improving students' English speaking skills. Employing a quantitative true experimental design, specifically a pre-test and post-test control group design, this research involved 36 eleventh-grade students at MA NWDI Ketangga, divided equally into an experimental class and a control class. Data were collected through a speaking test assessing pronunciation, fluency, vocabulary, grammar, and comprehension, and subsequently analyzed using the Mann-Whitney U test. The results revealed a highly significant difference in speaking performance between the two groups (U = 0.0, Sig. < 0.001). The experimental class achieved a massive post-test mean score of 90.44, significantly outperforming the control class's mean of 71.56, with the most prominent improvements observed in the aspects of fluency and pronunciation. In conclusion, the Stimuler Application is highly effective in accelerating oral proficiency by providing high-frequency independent practice and immediate AI-driven diagnostic feedback, thereby successfully reducing speech hesitation and lowering the students' affective filter.

Abstract

Although previous studies have examined smartphone-based assessment in EFL contexts, empirical research directly addressing teachers' experiences with smartphone-based summative assessment, particularly regarding its accuracy and implementation challenges remains limited. This study aims to explore teachers' perceptions of the smartphone-based summative assessment, to examine whether the results accurately reflect students' actual abilities, and to identify the challenges and benefits teachers experience in its implementation. This research employed a descriptive qualitative method, conducted at MA NW Korleko, involving two English teachers selected through purposive sampling. Data was collected through observation, semi-structured interviews, and documentation, and analyzed using an interactive model of data reduction, data display, and conclusion drawing. The findings show that smartphone-based summative assessment was effective in terms of administrative convenience and grading speed, but not yet effective in measuring students' English proficiency, as the application used could only assess two skills, reading and writing. Regarding accuracy, results did not always reflect students' true proficiency, as some students reportedly exploited a security loophole to bypass anti-cheating features. This study concludes that the effectiveness of smartphone-based summative assessment depends heavily on the quality of the application and the readiness of supporting technical infrastructure, rather than on the assessment method itself.
