Subject List پايان نامه هاي لاتين Gathering information about students’ reactions to open-ended questions is useful for understan‎ding the value of communication made by educators an‎d how it relates to motivation. The current research used sentiment analysis, which is an artificial intelligence technology, on students’ open-ended answers about Teacher-Engaging Messages. The proposed research used Natural Language Processing (NLP) polarity scores to investigate how Teacher-Engaging Messages have an effect on students’ sentiments. Finally, it investigated how students’ sentiments can be a mediator for Teacher-Engaging Messages on Motivation to Learn (MTL). A quantitative ex post facto research design was used with a total of 595 Iranian EFL (English as a Foreign Language) learners from Isfahan University of Technology as participants. Data were collected using the Teacher Engaging Message Scale (TEMS), the Academic Motivation Scale (AMS), an‎d an open-ended item. Data was analyzed using Structural Equation Modeling (SEM) to test the hypothesized links. Results indicated that students who perceive that their teachers use engaging messages have a more positive sentiment toward their teacher communication. Furthermore, results indicated that student sentiment acted as a partial mediator of the relationship between teachersʹ engaging messages an‎d student motivation to learn. Findings demonstrate the usefulness of sentiment analysis as a credible approach to examining the affective dimension of teacher-student interaction an‎d suggest the usefulness of collaboration between educational psychology an‎d artificial intelligence to obtain data-informed understan‎dings of the way teacher communication influences student motivation an‎d engagement in an EFL context. Keywords: Teacher-Engaging Messages; Sentiment Analysis; Motivation to learn; Natural Language processing; Teacher-student interaction; EFL context; Academic Motivation Grammatical metaphor (GM), a key element in systemic functional linguistics as proposed by Halliday, deals with the ways in which meaning can be manipulated at the grammatical level. By equipping texts with abstraction an‎d persuasion, GM serves as a fundamental linguistic feature in constructing formal an‎d technical genres. While it has been explored in both scientific an‎d non-scientific texts, comparative research on GM in journalistic discourse remains insufficient. This study explored the forms an‎d functions of GM in the environmental news of Inner, Outer, an‎d Expan‎ding circles of world Englishes through a qualitative approach, while also seeking to identify significant differences quantitatively across these varieties in terms of GM usage by means of SPSS 25. The corpus of this study consisted of 90 news articles in the timeframe of 2022-2024 (30 online news articles for each of the three circles of world Englishes). The focus of this study was the Stratal model of GM, which includes both ideational an‎d interpersonal metaphors. The qualitative results revealed that the dominant forms of GM in environmental news were ‘shift to thing’ an‎d ‘shift to quality.’ The findings of the quantitative analysis revealed that despite the absence of significant differences among the three circles of world Englishes in total GM usage, metaphor of modality appeared with higher frequencies in environmental news from the Outer Circle an‎d Inner Circle, respectively. Additional trends in GM implementation in environmental news across these varieties were observed through Mean Rank Comparisons. The findings of this study can equip language teachers with insights into the dominant forms of GM that are useful for writing instructions. Moreover, they provide valuable guidance for educators seeking to refine their teaching methods an‎d curricula to support students in developing persuasive writing skills effectively. Consequently, this study can contribute to promoting critical thinking by encouraging learners to move beyond surface-level information also it fosters register awareness. Enhancing knowledge about the forms an‎d functions of GM can also aid translators in identifying instances of it within texts an‎d ensuring appropriate translation wherever possible.
