Abstract

In the last two decades, teaching spoken English to EFL students has become a critical issue in the TESOL context. However, a few studies touch upon how EFL learners are taught to speak English spontaneously. Learning to speak English spontaneously in large classes becomes a big challenge for ESOL teachers because of space and time constraints. In response to this growing need, this article provides an empirical account of how modified role playing, more student-centered learning, is implemented as an innovative learning design in an EFL university setting where a large class is concerned. Data were garnered from open-ended and close-ended questionnaires, students’ personal narratives, and photovoices. These data were analyzed using Interpretative Phenomenological Analysis (IPA). Findings of the study show that the students were finally able to survive in their speaking tasks, engaging them in a real-life communicative encounter. This study concludes with some pedagogical implications for how a teacher as a curriculum designer engages students in motivating and anxiety-free speaking tasks.

Abstract

This study explores the relationship between entrepreneurship and ecological awareness with a focus on the Enzim Bakti community, using a descriptive qualitative approach. The Enzim Bakti community, known for its efforts in utilizing enzymes to support environmentally friendly practices, serves as a case study to understand how entrepreneurship can be integrated with the principles of ecological sustainability. Through in-depth interviews, observations, and document analysis, this study identifies various aspects of entrepreneurship implemented in this community and their impact on the ecological awareness of its members. The results show that entrepreneurship in the Enzim Bakti community is not only focused on creating economic value but also contributes significantly to environmental sustainability goals. Community members develop innovations that are oriented towards waste reduction, resource efficiency, and maintaining environmental quality. Ecological awareness, instilled through education and daily practices, plays a significant role in shaping entrepreneurial strategies that support environmental goals. These findings highlight that the integration of sustainability principles in entrepreneurship can have positive impacts on both business and the environment, and provide insights into how entrepreneurial communities can contribute to broader ecological awareness.

Abstract

Road damage indicates a condition where the structural and functional roads are no longer able to provide optimal service to traffic crossing the road. Traffic conditions and the types of vehicles that will cross a road greatly affect the design of construction planning and road pavement made. Asphalt or concrete pavement has frequent damage due to water entering the pavement so that it becomes damaged, this can be seen on Munif Rahman Street, Palu City, Central Sulawesi Province at Sta 0+000 – 2+200. The purpose of this study was to determine the relationship between vehicle speeds caused by various road damage conditions such as potholes, edge cracks, grain release, crests on Road Munif Rahman, Palu City, especially Sta. 0+000 – 2+200. The method used to determine the speed of the vehicle is the Spot Speed, and the Pavement Condition Index (PCI) method to determine the condition of the road pavement. From the results and discussion, some conclusions that can be drawn are the regression equation obtained is y = -0.0029x2 + 0.4101x + 10.841. R2 (R Square) obtained is R² = 0.3789. This means that the relationship between road damage and vehicle speed is 38% (poor), showing the relationship between the level of road damage and vehicle speed, that the lower the PCI value, the slower the vehicle speed as in Sta 1+900 to 2+000 with a PCI value of 13. (very poor) then obtained a vehicle speed of 14.611 km/hour. The results are inversely proportional to the influence of several factors in the research conditions, namely Sta. 1+300 to 1+400 with a PCI value of 33 (medium) then the vehicle speed is 26,800 km/hour, indicating that the lower the PCI value, the faster the vehicle speed, this is influenced by the driver, obstacles, and vehicle disturbances along the way. Munif Rahman street, Palu city.

Abstract

This study aimed to analyze the implementation of the Visible Thinking Routine (VTR) in Nurul Fikri Islamic School as an approach to training students' thinking skills. Using the survey research methodology, data were collected through observation, in-depth interviews with the science teacher population, and document analysis. The study's results stated that the use of VTR has a varied pattern, with a reasonably high adoption rate in Islamic Elementary School (IES) and Islamic High School (IHS) in certain months. At the same time, Islamic Middle School (IMS) recorded lower and consistent usage; IES was more active in implementing VTR in the last months, while IHS tended to be consistent throughout the month in this study. However, a significant issue in its implementation is the teacher's paradigm, which views the primary focus of learning as completing the subject matter, limiting the broader application of VTR as a tool for developing critical thinking skills. In addition, the biggest obstacle in implementation is the teacher's paradigm, which views the main focus of learning as completing the subject matter. VTR has a strategic role in training thinking skills and has yet to become the main focus of the learning process. This study recommends strengthening teacher training programs and integrating VTR into learning planning to improve teaching effectiveness in Islamic schools.

Abstract

This study examined the differences in sperm quality and metabolite profiles among X and Y sperm in Friesian Holstein bulls. It also tried to find specific metabolites that can help improve the accuracy of sexed semen use in humid tropical dairy farms. Semen samples from five bulls were separated by sex and tested for movement, live sperm count, shape, and membrane and acrosome health. The tests used Computer-Assisted Sperm Analysis (CASA) and regular microscope checks. Metabolite analysis was performed using LC-HRMS, followed by various statistical tests, pathway checks, and ROC curve analysis. The outcomes showed that X sperm had better movement and acrosome health, while Y sperm had stronger membranes, fewer shape problems, and moved faster. The untargeted metabolite study showed clear differences between the two groups. X sperm had more identified metabolites and greater average levels. The crucial metabolites found more in X sperm were D-(−)-fructose, L-(+)-lactic acid, and sn-glycero-3-phosphocholine. Meanwhile, Y sperm had greater levels of acetyl-L-carnitine. The pathway analysis showed that X sperm primarily utilized carbohydrate and fat processing through glycolysis and phosphocholine pathways to maintain their movement and membrane integrity. On the other hand, Y sperm mainly use a carnitine-based energy pathway to support their faster and straighter movement. The identified metabolites can serve as reliable biomarkers to aid in laboratory quality control checks and enhance the quality of semen extenders. This outcome gives a good way to make sexed semen more stable and reliable in tropical dairy farming conditions.
