Daylight Optimization of the South-Faced Architecture Classrooms Using Biomimicry-Based Kinetic Facade Shading System
Authors:   University Metropolitan Tirana, Tirana, Albania, Yunitsyna Anna , Sulaj Esi ,   Epoka University, Tirana, Albania
Published: January 2025

Building design is a product of multiple factors, such as concept and aesthetics, building materials and technologies, environmental conditions, and daylight requirements of the inner spaces. Biomimicry is an innovative approach that is used for the design of adaptable kinetic façade systems that can emulate the behavior of living organisms and provide an optimal solution to reduce heat gain and visual discomfort. This research is focused on the evaluation of the daylight performance of the south-facing architectural studios of the university building and the further proposal of a parametric shading system that emulates nature-based behavior. The study proposes multiple scenarios of kinetic façade behavior based on different degrees of openness and location of the shading elements. Computational simulations are used to evaluate visual comfort and find the solution that increases the use of natural light and provides visual comfort in the studios. The study considers the range of activities performed by architecture students, such as modeling, drawing, reading, writing, and computer use. As a result, several scenarios are selected, providing façade design that varies depending on the season and classroom.
Neon signage as cultural placemakers in America
Authors: Cempellin Leda
Published: January 2025

This exploratory qualitative case study examines the cultural significance of Carlos and Ed Garcia’s neon sign collection as components of American cultural heritage. By integrating secondary sources from human geography, cultural history, and philosophy, along with conversation with Carlos Garcia and photographic documentation primarily from the Garcia collection, this study analyzes how neon signs in American landscapes embody the interplay between mobility and permanence. These signs transition from functional advertisements to nostalgic artifacts, sparking reflections on the tension between historical restoration and artistic revitalization. The presence of these grandfathered and orphan signs in situ, long after the associated businesses have closed, stands as the last nostalgic remnant resisting a sense of placelessness, where unique local identities are overshadowed by corporate landscapes. Removal of these signs from their original locations and reorganization within a private museum underscores the tension between original and reimagined contexts. The findings provide a deeper understanding of the cultural narratives embedded in neon signage from this collection, emphasizing their unique value in American cultural heritage and their evolving role in expressing and interpreting communal and cultural identities.
Contextual Effects to Modulate Sign Adherence

Published: January 2025

Dynamic message signs (DMS) are crucial traffic control devices on roads, delivering real-time traffic conditions and valuable information to drivers. Several state transportation agencies developed non-traditional or creative messages for DMS with the intent to modify driver behavior. However, there is no scientific evidence to support the effect that creative messages have on changing behavior. The purpose of this study is to investigate how drivers with diverse demographic backgrounds respond to traditional and creative messages related to different message categories (work zone, maneuvering, speeding, and visibility) in a controlled setting using a driving simulator. Ninety-two participants were recruited for the experiment and each participated in sixteen scenarios. Statistical analyses revealed that creative signs led to a significant increase in time-to-collision with reduced lane position shifts compared to traditional signs, which indicated safer conditions. Also, when the number of words on DMS increased to between six and eight, speed decreased, suggesting a positive outcome related to the processing of information and responding while driving. Overall, the results of this study indicate that creative messages significantly improve driver behavior, clearly highlighting their advantages over traditional messages.

Apuntes históricos sobre los orígenes del servicio militar obligatorio
Authors: Atehortúa-Cruz Adolfo León
Published: January 2025

La propuesta del servicio militar obligatorio como fundamento para la construcción del Estado Nacional aparece en la historia con múltiples ejemplos. Para algunos autores, como Charles Tilly, el Estado no solo precisa de la coerción, sino que nace y se construye a partir de ella; un fenómeno que, por lógica, es detentado a través de un aparato armado permanente, compuesto por soldados en su base —hombres compelidos a desempeñar funciones militares— y oficiales profesionales, académicamente formados. El presente artículo de investigación aborda el carácter obligatorio del servicio militar en sus orígenes, prestando especial atención a los antecedentes y a su surgimiento en Francia y Alemania, modelos de la conscripción moderna. La historia global se convierte en trasfondo mediante el análisis de la guerra y sus desarrollos.
¡Otra vez prueba! Construcción epistémica de sentido común de la evaluación educativa en futuros docentes
Authors: Maldonado-Fuentes Ana Carolina , Sandoval-Rubilar Pedro Rodrigo , Tapia-Ladino Mónica
Published: January 2025

Disponer de antecedentes empíricos acerca de la evaluación de los aprendizajes como objeto representado por futuros profesores es fundamental para atender con pertinencia su formación. En particular, se vuelve más necesario ante las nuevas propuestas de estándares docentes que explicitan el dominio de saberes pedagógicos. Este artículo de investigación presenta un estudio de carácter descriptivo que investigó las connotaciones atribuidas a la evaluación por futuros profesores de una universidad regional chilena. En un muestreo por conveniencia, participaron 105 estudiantes de Formación Inicial Docente, que cursaron estudios universitarios durante 2021. Mediante preguntas abiertas y la técnica de Asociación Verbal se recoge información acerca de cómo los participantes definen y caracterizan las evaluaciones a partir de la experiencia escolar. El análisis de contenido interjueces facilitó la identificación de diez categorías para interpretar los datos, los que se sintetizaron en 23 de los términos asociados. A nivel de jerarquización, las palabras definidoras del núcleo central aluden a instrumentos, tipos de ítems y estados emocionales negativos. Estos hallazgos dejan en evidencia la tendencia a una mirada naturalizada, de una episteme de sentido común inexperta de la evaluación. Se sugiere diagnosticar estas connotaciones para el trabajo formativo desde el ingreso a la formación inicial.
Tensions and Turning Points: A Narrative Study about Professional Identities of Two Colombian English Teachers
Authors: Castañeda-Trujillo Jairo Enrique , Largo-Rodríguez José David
Published: January 2025

This research article explores the tensions and turning points experienced by two English teachers from the onset of their careers to their enrollment in a Master’s Degree program in Applied Linguistics For Teaching English. As researchers, we assume that the process of becoming an English teacher is social and co-constructed over time. Within this co-construction, the English teachers underwent moments of tension through which they had to make goal-oriented decisions related to their profession. Theoretical constructs suggest that identity construction is a dynamic and fluctuating process, with teachers continuously using their agency and investing in constituting their identities. The methodology employed written autobiographical narratives and narrative interviews for data collection. The analysis of these narratives revealed a sequence of critical moments that significantly influenced the formation of the participants’ identities, highlighting the role of agency in navigating emerging tensions. Findings indicate that teacher identity construction is influenced by the destabilizing nature of teacher education programs and the inherent tensions within these programs and teachers’ broader professional journeys. The study concludes by emphasizing the need for teacher education programs in Colombia to support teachers’ identity construction, enabling them to integrate and reflect their evolving self-conceptions in their pedagogical discourses and practices. The pedagogical implications rely on how teacher education programs in Colombia understand and support the construction of teacher identity and how teachers embody and reflect their new understanding of themselves in their pedagogical discourses and praxis.
Estrategias metacognitivas en el desarrollo del pensamiento crítico en inglés como lengua extranjera
Authors: Galarza-Guevara Alexandra Elizabeth , Pérez-Barral Osmany , Hernández-Junco Varna
Published: January 2025

El presente trabajo de investigación buscó determinar la relación entre las estrategias metacognitivas y el pensamiento crítico en la enseñanza de inglés como segunda lengua, con el fin de mejorar el pensamiento crítico. Con un enfoque cuantitativo y mediante un diseño cuasi-experimental, se hizo un estudio correlacional través de dos instrumentos: los cuestionarios Metacognitive Awareness Inventory (MAI) y Cornel Critical Thinking Test Level Z, aplicados a 50 estudiantes de cuarto nivel del Centro de Lenguas de la Pontificia Universidad Católica Sede Ambato. Para ello, se llevó a cabo una validación por parte de expertos, quienes evaluaron los instrumentos. Después de su aplicación, se evidenció una correlación positiva entre la metacognición y el pensamiento crítico, utilizando al prueba Wilcoxon. Se obtuvo un valor de p (Sig. asintótica (bilateral)) inferior a 0,01, lo que permitió concluir que, cuanto más se utilicen estrategias metacognitivas, los estudiantes pueden potenciar las áreas de pensamiento crítico, tales como la interpretación, el análisis, la evaluación y la autoevaluación, la inferencia, la explicación y, en especial, la autorregulación y el autoaprendizaje de una segunda lengua.
Cinco experimentos de naturaleza urbana: relatos desde un nicho de los Cerros Orientales de Bogotá
Authors: Mejía María Angélica , Wiesner Diana
Published: January 2025

Bogotá cuenta con una de las reservas naturales urbanas más grandes de América Latina: los Cerros Orientales. Aunque sus 14 000 ha de áreas verdes urbanas benefician indirectamente a toda la población de la ciudad, un estudio realizado por Greenpeace Colombia en 2020 concluyó que el 80 % de los habitantes de Bogotá tienen un déficit de áreas verdes. De las diecinueve localidades de la ciudad, trece presentaron esta carencia. Estos resultados ponen en evidencia los desafíos que enfrenta Bogotá en términos de distribución y acceso a la naturaleza y sus beneficios. De otra parte, la ciudad ha sido protagonista de movilizaciones ciudadanas emblemáticas en defensa de la naturaleza urbana, especialmente en relación con los humedales y los Cerros Orientales. En este escenario dinámico, la Fundación Cerros de Bogotá (FCB) desarrolló una propuesta técnica para crear el corredor socioecológico más grande y diverso de nuestra región: 57 kilómetros de biodiversidad y tejido social. Este artículo presenta tres experimentos de acupuntura urbana que buscan hacer realidad ese sueño. En los últimos ocho años, más de 6500 personas han participado en actividades lideradas por la fcb en la Reserva Umbral Cultural Horizontes enfocadas en los siguientes aspectos: i) restauración ecológica y construcción de infraestructura para recuperar el suelo, el agua y la biodiversidad; ii) fomento de una cultura ecológica ciudadana, integrando el arte como herramienta de transformación, y iii) incidencia en política pública. Este artículo presenta los principales lineamientos metodológicos que hemos desarrollado en cada frente de acción, junto con recomendaciones que, esperamos, puedan replicarse.
Principios para la formación de escritores en posgrado
Authors: Narváez-Cardona Elizabeth , Chois-Lenis Pilar Mirely
Published: January 2025

Los estudios e intervenciones educativas sobre la escritura en posgrado son aún incipientes; por eso, contribuir con reflexiones sistemáticas de intervenciones educativas puede aportar tanto a comprender el complejo fenómeno de formación de escritores a lo largo de la vida como a nutrir la agenda educativa global que incluye el incremento de la matrícula de posgrado. En este artículo, derivado de una sistematización, las autoras presentan cinco principios para la formación de escritores en posgrado basados en el análisis de narrativas propias asociadas a sus experiencias pedagógicas. Dicho análisis muestra que futuras iniciativas de trabajo deben: 1) explorar prácticas pedagógicas para apoyar el uso de las retroalimentaciones en relación con la construcción identitaria y autorial de los estudiantes; y, 2) realizar estudios longitudinales que pongan en relación experiencias letradas y el desarrollo de la conciencia de los géneros discursivos.
Relación de las teorías implícitas del profesorado sobre la enseñanza con compromiso escolar estudiantil y clima motivacional de clase en educación superior
Authors: Bravo-Verdugo Edwin Ricardo , Fernández-Heredia Blanca de la Luz , Moreno-Candil David , Meza-Calleja Adriana Marcela , Barrios-Campos Ricardo , Xelhuantzi-Santillán Rafael Izcoatl
Published: January 2025

México se encuentra en un periodo de reforma educativa, la cual pretende universalizar la educación superior reconociéndola como un bien público y un derecho. De este modo, se establece la Ley General de Educación Superior, que busca garantizar que la educación superior sea laica, pública, gratuita, inclusiva y universal. Para ello, se reconoce al profesorado como un elemento clave; sin embargo, se enfrenta el desafío de modificar las prácticas docentes, lo cual requiere conocer el pensamiento docente. El concepto de teorías implícitas resulta esencial para este análisis, ya que estas orientan la práctica. A su vez, la práctica docente establece climas de aprendizaje que impactan en el compromiso escolar del estudiantado. El objetivo de este estudio fue explorar la relación entre las teorías implícitas, el clima motivacional de clase y el compromiso escolar. Se usó un diseño no experimental de alcance correlacional, con una muestra compuesta por docentes y estudiantes de una universidad pública mexicana. Los resultados mostraron que el pensamiento docente se conformó de ideas posmodernas, emancipatorias y tecnicistas. No se encontró una correlación entre el clima motivacional de clase y el compromiso escolar. Sin embargo, se vislumbró una relación entre la teoría implícita dominante de distintos docentes y la evaluación del clima de aprendizaje realizada por sus estudiantes. Los docentes con una teoría implícita emancipatoria fueron mejor evaluados que aquellos con una teoría posmoderna. Estos resultados aportan evidencia de la relevancia de la perspectiva pedagógica que orienta las reformas educativas actuales en México.

Authors: Herrera-Cortés Martha Cecilia , Quintero-Garzón Cindy Johana
Published: January 2025

Este artículo de reflexión hace parte de las reflexiones y resultados de la investigación Perspectiva infantil en la literatura colombiana: del retorno a la infancia a las infancias figuradas, financiado por el Centro de Investigaciones de la Universidad Pedagógica Nacional de Colombia. Aborda algunas de las obras literarias de Ricardo Silva Romero y Melba Escobar de Nogales, con el propósito de auscultar arquetipos en torno a la infancia y sus conexiones con el ser humano, de modo que se constituyan en puentes de diálogo con lecturas en torno a los nuevos procedentes del campo de la pedagogía y alimenten las discusiones a propósito de la relación entre literatura, infancia y educación. De la mano de Bachelard, se señalan las posibilidades de la ensoñación –características de la infancia– presentes en la escritura poética y literaria, para concluir que estas permiten abrir las puertas de la imaginación y de otros mundos posibles.

Authors: Díaz-Pareja Elena María , Cámara-Estrella África , Barrero-Fernández Beatriz
Published: January 2025

Conseguir crear comunidades inclusivas es un proceso compartido en el que deben implicarse todos los agentes educativos, labor que debe ser impulsada desde un liderazgo inclusivo que fomente la participación y la adecuada respuesta a la diversidad. Por ello, en esta investigación nos centramos en analizar cómo percibe el profesorado de los centros andaluces la labor desarrollada por el equipo directivo en este ámbito. Se presentan los datos recogidos tras aplicar un cuestionario a 747 docentes para valorar el grado en el que el liderazgo ejercido por la dirección de los centros educativos favorece la inclusión. Se han realizado análisis descriptivos y análisis inferenciales, comprobándose que existen diferencias estadísticamente significativas. En general los docentes valoran positivamente las iniciativas para el fomento de la participación de todos y la comunicación con las familias, mientras que las prácticas que consideran que necesitan mejorar están relacionadas con las acciones emprendidas para colaborar con otros centros, con el mundo empresarial y con la participación de los miembros de la comunidad educativa en la evaluación de las labores de dirección. Podemos decir que la gestión de los líderes escolares está bien valorada por los equipos docentes, pero aún quedan retos por conseguir.

Authors: Torres-Sánchez Julián Darío , Zapata-Castañeda Pedro Nel
Published: January 2025

El presente artículo tiene como objetivo establecer un marco de referencia para la caracterización de los procesos cognitivos que subyacen al pensamiento tecnológico (pt), mediante una revisión de diversas fuentes documentales orientadas al estudio de los procesos cognitivos y a la enseñanza de la tecnología. El propósito de esta revisión fue caracterizar los procesos cognitivos que intervienen cuando se piensa tecnológicamente. En este sentido, se recopilaron, seleccionaron y organizaron diferentes fuentes documentales relacionadas con el pt y los procesos cognitivos implicados en este tipo de pensamiento. Adicionalmente, se contrastaron los diversos postulados teóricos de diferentes autores frente al tema y, finalmente, se planteó una interpretación propia de los procesos cognitivos que estructuran el pt. Los resultados de la revisión se presentan en tres apartados: procesos cognitivos asociados al pensamiento tecnológico, procesos cognitivos asociados a la solución de problemas (sp) tecnológicos y procesos cognitivos relacionados con el uso de herramientas tecnológicas. Entre los hallazgos más importantes se destaca la ubicación de los procesos de razonamiento tecnológico en el área frontoparietal dentro del lóbulo parietal inferior izquierdo y la existencia de procesos cognitivos exclusivos de la especie humana dentro del contexto tecnológico. Como conclusión, en este texto se finaliza reconociendo nueve procesos cognitivos que subyacen al pt.
Explorando el vínculo entre las emociones y el Conocimiento Didáctico del Contenido (CDC) en la formación inicial docente
Authors: Retana-Alvarado Diego Armando , De las Heras Pérez María Ángeles , Vázquez-Bernal Bartolomé , Jiménez-Pérez Roque
Published: January 2025

Las emociones del profesor conforman el Conocimiento Didáctico del Contenido (CDC) e influyen en la enseñanza. Este estudio analizó una práctica de aula que considera las emociones en el CDC, relacionado con la Hipótesis de la Complejidad. Utilizando un método etnográfico, se examinó el clima emocional y su rol en el modelo teórico. Se entrevistó a una formadora experta, quien reflexionó sobre su práctica con docentes en formación inicial en la Universidad de Huelva (España) durante el curso académico 2016-2017. Se creó un sistema de categorías para analizar el contenido y la relación entre códigos. Los resultados indicaron que la interacción emocional es modulada por facilitadores u obstáculos afectivos y cognitivos. Las emociones se incorporan en la planificación y reflexión docente, estableciendo un modelo didáctico afín con el CDC personal. La formación inicial requiere educación emocional dentro de un modelo profesional con estrategias de metacognición y autorregulación.
Historietas conceptuales contextualizadas, una estrategia didáctica para comprender el territorio como construcción social
Authors: Falla-Falla Ana María , Bustos-Velazco Edier Hernán , Reyes-Roncancio Jaime Duván
Published: January 2025

Este artículo expone la investigación propuesta dentro del paradigma cualitativo y bajo un enfoque interpretativo con la finalidad principal de desarrollar dos Historietas Conceptuales Contextualizadas (HCC) e implementarlas como estrategia didáctica, motivadora, contextual y reflexiva para posibilitar la discusión y comprensión del territorio como construcción social en el aula. A través de situaciones específicas se busca identificar y establecer la relación, implicaciones e ideas que tienen los estudiantes sobre el territorio del cual hacen parte, y al cual construyen, apropian y transforman. Del mismo modo, la estrategia se basa en el interés de orientar, fortalecer y/o consolidar actitudes de valor, respeto, cuidado y preservación del ambiente. Finalmente, el trabajo de investigación permitió concluir que las HCC configuran elementos encaminados al fortalecimiento de la conciencia, sensibilidad y responsabilidad ambiental, teniendo en cuenta que las ideas globales extraídas de las apreciaciones de los estudiantes, a partir de los instrumentos aplicados y analizadas posteriormente a la luz de las categorías teóricas y los indicadores establecidos, evidencian que respecto a las situaciones propuestas y las preguntas planteadas realizan descripciones de su realidad y/o cotidianidad, mencionan características de los espacios físicos, relacionan conceptos con el ambiente y/o elementos de este, señalan algunas situaciones referentes a normatividad, ejercicios de poder y aspectos legales. Además, se refieren a la importancia de encontrar consensos entre los actores sociales y proponer soluciones a problemáticas del contexto enunciando el presente y futuro a nivel ambiental, social, económico y político.

Observou-se que tal aprimoramento ocorre quando a professora/pesquisadora avalia criticamente sua práxis no contexto do itinerário formativo analisado, destacando a importância de conhecer e refletir sobre os componentes do PCK. Esse processo contribui para qualificar tanto as concepções quanto as ações envolvidas na formação continuada de professores de Química.
[DES]ENCUENTROS Y [DES]PROPUESTAS: LA EVOLUCIÓN DE LA PROPUESTA DE BASE CURRICULAR NACIONAL COMÚN (BNCC) EN LA MAREA DE LA POLÍTICA BRASILEÑA
Authors: Oliveira Lucas Sávio Freire da Silva , Lima Jeylla Salomé Barbosa dos Santos
Published: January 2025

Fruto de la ampliación de un proyecto de investigación iniciado y aceptado en 2022 (Oliveira; Salomé, 2022), este trabajo busca ampliar y problematizar las circunstancias que rodearon el desarrollo de la hoy controvertida Base Curricular Nacional Común (BNCC) (2014 - actual) (Macedo, 2014, 2015). Sin embargo, su objetivo también es articular los fundamentos que sustentaron esta germinación con los últimos veintisiete años de algunas políticas educativas en Brasil, es decir, el período que va desde el inicio del gobierno de Fernando Henrique Cardoso (FHC) en 1995 hasta el de Jair Messias Bolsonaro (2019-2022). La investigación adopta una metodología bibliográfica, de naturaleza cualitativa y enmarcada en un paradigma de investigación científica interpretativo-constructivista (Bogdan; Biklen, 1994; Morse, 2007), que implica la consulta de textos fruto de investigaciones científicas y documentos encontrados en la literatura específica, desde una perspectiva de reflexión subjetivamente situada en la criticidad analítica, que, a su vez, se alinea con la metodología. Desde esta perspectiva, se buscó indagar cómo los últimos cinco gobiernos presidencialistas-partidistas del país han conducido algunas de sus principales políticas educativas, para contrastarlas con el seguimiento e implementación de una Base Nacional Común (BNC), que se canalizaría como la “BNCC”. Como resultado, se constató que la desarticulación, discontinuidad y desmembramiento de las políticas educativas entre los gobiernos (e incluso dentro de ellos) (Gandra; Dering, 2019) - combinada con el desapego del escenario de enseñanza y aprendizaje en Brasil - han afectado críticamente la calidad de la educación impartida a la población brasileña, afectando, de diferentes maneras, a todas las partes involucradas en el proceso de desarrollo humano integral que la escuela puede proporcionar. Como conclusiones, destacamos la [todavía] ineficaz actuación del BNCC en la promoción de una educación socialmente justa y democrática - actuación, a su vez, fuertemente entrelazada con el escenario político, y no exenta de ingenuidad o neutralidad.

The Case for Mediation: A Conceptual Review
Authors: Xirofotou Evangelia
Published: January 2025

This conceptual review investigates the use of mediation in English language teaching contexts. Following a review of mediation and its background and uses. The Common European Framework of Reference for Languages (CEFR) and multilingualism are explained, along with its history and goals. The various definitions of mediation are examined, including those from the CEFR, as well as definitions related to translation and interpretation, and the one underpinning the mediation aspect of the National Foreign Language Exam System (KPG). It is argued that mediation is critical in all linguistic, social, and cultural contact zones, including language teaching and learning contexts. Mediators have a vital role in settings where the meanings of languages, identities, and relationships are being reassessed and renegotiated, and English as a foreign language (EFL) learners' mediation ability should be developed to enable them to fulfill this critical role in society. Teaching mediation strategies should constitute a new objective in foreign language learning and teaching by adopting new methodological approaches.
The Criteria and Challenges in Evaluating the Performance of the Writing Skills of German Language Students
Authors: Rexhepi Sadije , Suka Çliresa
Published: January 2025

The goal of this study was to learn how the performance of German as a Foreign Language (GFL) writing skills is evaluated, what criteria it is based on, and what challenges can be expected during the evaluation. Performance measurement is a challenge for many, and previous research and experience show that when it comes to productive abilities, writing takes a back seat in the classroom, where speaking skills are prioritized. Nonetheless, since the focus of this study is on German writing skills, it is important to clarify their role in GFL teaching. Although there are different aspects and criteria for the assessment of productive and writing skills, some are more important than others. The study takes a theoretical and empirical approach, utilizing a questionnaire and interviews to analyze the perspectives of both examinees (students) and examiners (teachers). For a justified assessment, certain quality criteria are considered, including objectivity, reliability, and validity. Additionally, the study also references Goethe, ÖSD, and TELC model tests, as well as other test forms used in private schools and university courses in Kosovo. Thus, this research focuses not only on the various forms and functions of performance measurement but also on the potential obstacles that may develop during assessment and how to avoid and fix these issues.

Enhancing Vocabulary Acquisition Efficiency Through Metacognitive Strategies and Vocabulary Tasks: A Study of EFL Learners in a Taiwanese University of Technology
Authors: Tu Hsiu-Lien
Published: January 2025

Recently, universities of technology in Taiwan have shifted their emphasis from teaching everyday English to workplace English to improve graduates' employability. Such a transformation has presented significant challenges to college students from universities of technology with low learning proficiency. Particularly when acquiring workplace English vocabulary, including unfamiliar terminology, a large number of complex words, and diverse meanings, EFL learners in universities of technology frequently confront a range of obstacles. Therefore, learners need to implement effective learning strategies, such as metacognitive strategies, to enhance their vocabulary acquisition proficiency. In addition, educators can design appropriate vocabulary task activities to improve learners' vocabulary acquisition efficiency. This study aims to investigate the efficacy of learners' metacognitive strategies and suitable vocabulary tasks in enhancing their vocabulary acquisition efficiency. The results reveal that frequent utilization of metacognitive strategies improves vocabulary acquisition in comparison to low-frequency users. Furthermore, the degree of vocabulary task involvement also impacts vocabulary retention. These findings demonstrate that metacognitive strategies and vocabulary tasks can promote vocabulary acquisition and provide educators with an opportunity to improve English vocabulary learning efficiency for EFL learners in universities of technology.
Psychological Suggestive Connotations in Fahd Al-Askar’s Poetry: “Woman and Wine” Poem as a Model
Authors: Al-Gayam Ismeel M. M. , Al-Rawashdeh Basma A. S. , Essa Ahmad H. M. Bany , Rababah Mahmoud A.
Published: January 2025

This study explores the existentialist ideas and perspectives of the poet Fahd Al-Askar played a prominent role in challenging societal values and traditions, which he viewed as obstructing freedom and social justice. The study employed a descriptive analytical approach to analyse Al-Askar’s poetry. The results revealed that Al-Askar, as a poet with a mission, undertook the defense of his society's people, striving to spread intellectual and religious freedom. He used the themes of “woman” and “wine” as effective tools to convey his intended message. The “woman” was both a means and an end: a means to provoke societal taboos through sensual poetic descriptions, and an end to advocate women's recognition of their existence, identity, and right to participate equally in social roles alongside men. Sensual depictions served more as a pressing tool rather than an intrinsic purpose. As for “wine,” it represented another tool that Al-Askar utilized to challenge traditional societal norms. Being religiously forbidden, it served to create tension and provoke the customs of a conservative and committed society. By focusing on the central connotations of both “woman” and “wine,” Al-Askar infused them with suggestive and psychological peripheral meanings to produce the desired implications.

This study examines the impact of ChatGPT on reducing the affective filter and enhancing speaking proficiency among EFL medical track students. An experimental group of 18 students participated in speaking practice facilitated by artificial intelligence (AI) tools using ChatGPT. Specifically, the influence of ChatGPT was evaluated on motivation, self-esteem, and anxiety levels among English as a foreign language (EFL) learners. A mixed-methods approach was employed, combining quantitative and qualitative data collection through pre-posttests on speaking proficiency, as well as interviews. Results indicate a significant positive shift in students' anxiety levels post-intervention, along with improvements in speaking performance and reduced affective filter. ChatGPT's role in providing personalized feedback, simulated conversations, and a supportive learning environment is highlighted as an asset in language learning and emotional barrier mitigation. Further exploration into the long-term effects of AI technology in language learning is recommended to enhance teaching practices and create inclusive learning environments.

Authors: AlSalem Abeer S.
Published: January 2025

This study examined Arabic language teachers' conception of argumentative writing and their perceptions towards developing argumentative writing skills among middle school students. It also sought to identify the factors that affect or hinder teachers' implementation of teaching argumentative writing skills in middle schools in the Kingdom of Saudi Arabia. The study employed a mixed-method approach with a sequential explanatory design. The study collected data from 260 middle school Arabic language teachers using a structured questionnaire with five sections covering: their conceptions of argumentative writing, their conceptions of argumentative writing skills, their perceptions of the importance of developing these skills in middle school students, their perceptions of the requirements for developing these skills, and their perceptions of the obstacles to developing these skills. Additionally, a semi-structured interview was conducted with nine female teachers to provide qualitative insights and further contextualize the quantitative survey findings. The findings revealed that middle school Arabic language teachers held a moderate level of perceptions towards the development of argumentative writing skills among their students. Based on these findings, the study recommended that the Arabic language curricula in Saudi middle schools should place a greater emphasis on cultivating argumentative writing skills, given their importance in refining students' personalities and enhancing their ability to express opinions and persuade others.

The growing cultural consciousness and other needs emerging due to rapid globalization in contemporary times have led to an addition to the available literature in the translation subfield of film subtitling. This has created new challenges for the learners enrolled in translation courses. However, the problem specific to the subtitling of films is relatively less researched, especially concerning learners' perceptions and attitudes towards it. This study aimed to bridge this gap, investigate the problems encountered by Saudi EFL learners in subtitling film content, and chronicle their suggestions for dealing with them. The study used a validated questionnaire to gather perceptions and attitude data from a large sample of 583 translation students across four Saudi universities in the second semester of the academic year 2021-2022. This phase lasted for almost four months. All the items in the questionnaire were loaded onto five factors. The findings showed a significant positive correlation between the number of translation courses/credited hours and participants’ knowledge, attitudes, applied practice, and suggestions for improving learning outcomes in their universities. The findings also established that Saudi EFL students face several challenges in subtitling, including linguistic, cultural, and technical problems, of which technical issues, followed by cultural issues, were perceived to top the list. Finally, there were no significant differences in the participants' perceptions attributable to the alma mater, indicating that the challenges are universal and that changes in policy, curricular, and pedagogical levels are needed in all participating universities.

This study examines politeness strategies employed by Muslim preachers in Arabic-scripted Friday Khutbah “sermons”, especially those available on the Internet. The data consist of four sermons delivered by renowned Saudi preachers in Mecca’s Haram, Muslims’ holiest mosque, and published on verified sites on the web. Findings reveal that the preachers have employed twelve distinct politeness strategies, based on Brown and Levinson’s (1987) four major types of politeness: positive face, negative face, off-record, and bald-on record. Positive politeness was found to be the most predominant. This suggests that the preachers tend to promote collective identity and mutual respect, in line with the principle of acceptance inherent in positive politeness. In addition, negative politeness, which emphasizes the listener’s autonomy, ranked second in frequency, consistent with the cultural norms, communicative intentions, and socio-religious sensitivities prevalent in Muslim communities. Through examining these sermons, this study contributes to broader research in politeness in religious discourse, providing data for comparison with earlier studies.

Published: January 2025

Engagement is a crucial part of language learning as it shows how much a learner is involved in the learning process. Language learning with engagement is considered meaningful. This study measured Saudi male college EFL students' L2 engagement levels while learning English as a foreign language in their preparatory year. The relationship between students' scores in the English course and their L2 engagement was also discovered. An L2 engagement scale with three engagement domains (behavioral, emotional, and cognitive) created by Hiver et al. (2020) was utilized to measure students' L2 engagement levels. Pearson correlation was administered to explore the relationship between students' learning success (scores) and L2 engagement. The results indicated high behavioral, emotional, and cognitive engagement levels. In addition, the results showed a statistically significant positive relationship between students' scores and their L2 engagement. Implications for educational establishments and language teachers were presented, as well as the impact on future research and limitations.
