Reading comprehension is essential in English language learning, yet many EFL learners continue to struggle with vocabulary, implicit meanings, and complex academic texts. Addressing these challenges requires innovative pedagogical approaches that go beyond surface-level instruction. This study reports on a needs analysis conducted to support the development of a Corpus-Based Language Pedagogy model integrated with AI for reading instruction. Data were collected through a questionnaire administered to Indonesian EFL students, focusing on their reading attitudes, challenges, and instructional expectations. The results reveal that students generally hold positive attitudes toward reading in English, particularly when authentic texts and interactive activities are incorporated. However, they experience notable difficulties with unfamiliar vocabulary, complex grammatical structures, and lengthy passages. Current classroom practices are often limited to surface-level comprehension, which students perceive as inadequate for developing critical and analytical reading skills. In contrast, learners express the need for authentic corpus-based materials, relevant vocabulary, and contextualized reading strategies. They also highlight the importance of integrating technology and AI to enhance engagement and facilitate deeper comprehension. The study concludes that a corpus-based approach integrated with AI can provide authentic language input, expand lexical knowledge, and foster data-driven learning. The proposed model, therefore, offers a promising framework for improving students’ reading competence in the EFL context.
Sustainable teacher professional development requires school-based organizational mechanisms that enable continuous collaboration, reflection, and professional learning. This study aimed to analyze the management of the SeBAIK CANDA Professional Learning Community (PLC) in supporting sustainable teacher professional development at an Indonesian elementary school. A qualitative approach with a case study design was employed at SD Negeri Candirejo 02 Ungaran Barat, Semarang Regency, Central Java, Indonesia. Ten participants were purposively selected, comprising one principal, seven classroom teachers, and two learning community coordinators. Data were collected through semi-structured interviews, observations, and documentation and analyzed using inductive thematic analysis adapted from the interactive model of Miles, Huberman, and Saldaña. Research credibility was strengthened through source and technique triangulation, member checking, and an audit trail. The findings revealed five interconnected dimensions of sustainable PLC management: structured planning and organization, collaborative and reflective professional learning, supportive school leadership, continuous evaluation and follow-up, and adaptive organizational support. Professional discussions, peer feedback, experience sharing, classroom-based reflection, and follow-up activities strengthened collective responsibility for teacher learning and connected professional development with instructional practice. Although limited time, administrative workload, scheduling conflicts, and differences in professional readiness constrained program continuity, teacher commitment and flexible communication supported sustained professional interaction. The study proposes a sustainable PLC management framework that positions professional learning communities as organizational systems for continuous, collaborative, reflective, and school-embedded teacher professional development.
Meaning extends beyond the literal form of language since it is a dynamic system. Defixis is a remarkable pragmatic phenomenon in language usage; it refers to a collection of statements whose meaning is contingent upon characteristics including speaker, place, time, discourse, and social context. Everyday speech, literary works, and creative expressions (such as song lyrics) all include deixis. Songs are great resources for linguistic analysis and language acquisition because they provide rich contextual references, which are a result of the language's genuine usage. There is a dearth of literature on pragmatics in literary and media texts, although there is some study on deixis in song lyrics, especially as it pertains to ELT. The purpose of this research is to dissect the album Being Funny in a Foreign Language for its deixis and the pragmatic roles they play in certain tracks. Based on Levinson's (1983) theory, this research used a qualitative content analysis methodological approach to classify deixis as follows: personal, temporal, geographical, discourse, and social. Five songs were chosen at random using a purposive sample strategy to gather data for the investigation. As a source of information, documentation procedures were used to gather the official lyrics of the five songs. In addition, the data were evaluated by classifying different kinds of deixis and then determining how often each kind occurred. Out of a total of 482 deixis expressions, 455 were found to be personal (94.40%), 2 to be spatial (0.41%), 7 to be temporal (1.45%), 17 to be discourse (3.53%), and 1 to be social (0.21%), according to the findings. The study revealed that personal deixis was the most common form of deixis, with discourse, time, location, and social deixis following closely behind. Each of these types added to the rich contextual meaning found in the song lyrics. This discovery suggests that students' comprehension of pragmatic studies, particularly as it pertains to deixis, might be enhanced by using song lyrics as realistic teaching resources.
Limited access to affordable and consistent ball-feeding technology remains a practical challenge for table tennis training in schools and grassroots sports programs, particularly in resource-constrained environments. This study developed and preliminarily evaluated “Robopoly,” a low-cost table tennis ball launcher engineered from repurposed fan motors to support structured technical training. Its novelty lies in a sustainable mechanical design intended as an affordable alternative to commercial robotic systems. The development process included needs assessment, prototype development, expert validation, product refinement, and preliminary field testing. Content validity, assessed by four experts using Aiken’s V Index, yielded a mean score of 0.78, classified as feasible. A pre-experimental one-group pretest–posttest design involving 10 athletes was used to assess forehand and backhand stroke accuracy. The paired-samples t-test indicated improvements in forehand accuracy, t(9) = −4.25, p = .002, Cohen’s d = 1.34, and backhand accuracy, t(9) = −3.98, p = .003, Cohen’s d = 1.26. These findings provide preliminary evidence of short-term improvements in stroke accuracy following the use of Robopoly and indicate its potential to support consistent and repeatable ball-feeding practice in resource-constrained educational and community sport settings. However, the absence of a control group limits causal interpretation. Further controlled studies with larger samples and longer follow-up periods are needed to establish the effectiveness and longer-term training effects of the device.
Halal authentication using the polymerase chain reaction (PCR) technique relies on amplifying specific DNA sequences derived from non-halal sources, which requires thermostable enzymes such as Taq DNA polymerase. Currently, most commercial halal detection kits in Indonesia, as a Muslim-majority country, rely on imported Taq DNA polymerase enzymes for halal detection kits, resulting in limited access. In this study, the production of in-house recombinant Taq DNA polymerase (TaqPol) expressed in Escherichia coli BL21 Star (DE3) containing plasmid pD871 was optimized, and the TaqPol was applied as an enzyme in a halal detection kit in optimized condition. The optimization of expression parameters, including post-induction incubation time, IPTG concentration, and cell density (OD600), was carried out systematically. The optimum conditions obtained with maximum TaqPol production were a post-induction incubation time of 18 h, an IPTG concentration of 0.4 mM, and an OD600 of 0.6. Under these optimized conditions, the enzyme yield increased by approximately 145
