Critically ill patients admitted to the intensive care units (ICUs) often face numerous challenges, including severe metabolic stress, systemic inflammation, and compromised immune function. Studies have suggested that critically ill patients frequently experience a negative nitrogen balance due to a hypercatabolic state, leading to impaired organ function and muscle wasting, which can cause severe muscle weakness and physical disability for years after discharge. Arterial blood gases (ABG) reflect patients' oxygenation and acid-base status and are crucial indicators of respiratory and metabolic function in critically ill individuals. We aim to address this by conducting a double-blinded, randomized controlled clinical trial to compare the effects of standard feeding with a high-protein diet on ABG in ICU patients. In this double-blinded, randomized controlled clinical trial, we will use block randomization of 80 patients aged between 18 to 65 years old and Patients expected to be hospitalized in the ICU for at least 3 days from Kosar Hospital, Kurdistan, Iran. The intervention group (n=40) will receive a protein diet (consisting of 18.7% protein, 45% carbohydrates, and 35% fat per 1000cc). A control group (n=40) will receive a standard diet (14.4% protein, 54% carbohydrates, and 32.4% fat per 1000cc) for the same duration in addition to usual care. The caloric requirements of each patient will be determined by a nutritionist based on their nutritional status, height, weight, age, and initial diagnosis, utilizing the Harris-Benedict formula. The parameters of ABG, including PO2, PCO2, SAO2, HCO3, BE, and pH, will be assessed. By optimizing protein intake through a high-protein diet, we aim to improve the nutritional status of patients and enhance their overall clinical outcomes. This reassures us of the potential benefits of our study.

Clinical decision-making is a critical and essential skill in clinical care. Nurses' proficiency in proper clinical decision-making significantly improves the quality of nursing care. As an active learning approach, concept mapping education plays a vital role in deep learning and applying critical thinking skills in clinical decision-making. This study aimed to investigate the impact of concept mapping on clinical decision-making in nursing students. The study was an experimental design with two groups, where participants were randomly assigned to the test group (25 students) or the control group (25 students). Data were collected using the clinical decision-making questionnaire. Based on relevant literature, the test group participated in eight concept mapping sessions lasting 60 to 90 minutes each, while the control group received traditional lecture-based education. Covariance analysis, excluding the effect of the pre-test, showed no significant difference (P=0.86, eta=0.01). Still, a paired t-test revealed a significant difference in the test group before and after the intervention (P<0.01). The results demonstrated that concept mapping education enhances clinical decision-making. Therefore, this teaching method, which promotes students' reflection, creativity, and decision-making skills, is recommended in nursing education. Concept mapping is an effective, innovative, and cost-efficient educational strategy.

The present study was conducted to determine the effect of manual acupressure on uremic pruritus and quality of life (QoL) in patients undergoing hemodialysis. This randomized controlled trial was conducted with a pre-post design on 90 patients with hemodialysis in southern Iran. The patients were divided into three groups using block randomization: intervention, sham control, and passive control. The intervention group received acupressure on SP6, SP10, ST36, and LI11 points. In the sham group, pressure was exerted on sham points two Cuns away from the actual points, and the passive control group solely received routine treatment. The intervention was carried out three times a week for four weeks. The patient's QoL was evaluated before and after the intervention using the Itchy QoL scale, and the dimensions of itching were assessed before the intervention and two and five weeks after commencing the intervention using the 5-D Pruritus scale. The groups' QoL and itching parameters were the same before the intervention. The analysis of variance (ANOVA) showed significant differences among the groups in terms of QoL following intervention. This index improved significantly in the intervention group compared to the other groups (P<0.001, G1=107.20 (standard deviation [SD]=5.45)). Repeated measures ANOVA showed that acupressure significantly reduced the severity and duration of itching and the number of itching points in the intervention group. Acupressure can improve hemodialysis patients' QoL and itching sensations. Being a non-pharmaceutical, risk-free, and inexpensive method, this intervention could be recommended to be used for relieving uremic pruritus.

With the expansion of the global healthcare business market, nursing entrepreneurship is also expected to grow. The concept of entrepreneurship in nursing is linked to personal and professional attributes such as independence, flexibility, creativity, confidence, and responsibility. The challenges of entrepreneurship in nursing are categorized into three main areas: traditional nursing education perspectives, individual factors, and lack of support. The first challenge, traditional nursing education, includes subcategories like the absence of student start-ups, the lack of entrepreneurial content in nursing curricula, entrepreneurial knowledge among nursing educators, and the non-practical nature of nursing research in entrepreneurship. The second challenge involves individual factors, which include risk aversion, low self-belief, resistance to change, lack of knowledge, conflicting ideas, and lack of perseverance. It's important to note that perseverance is vital to overcoming these challenges. The third challenge is the lack of social support for nursing entrepreneurship, which includes subcategories like job burnout and unprofessional behavior from peers. Based on the results of this study, nursing curricula must be reviewed, with greater emphasis placed on entrepreneurship during postgraduate education. Increasing entrepreneurial knowledge and skills among nurses can enhance problem-solving abilities and risk-taking in nursing. This, in turn, can increase motivation and job satisfaction in nursing.

The present study aims to determine the effect of the spiritual self-care model on the self-efficacy of spouses of veterans with post-traumatic stress disorder (PTSD). This quasi-experimental study, conducted in 2023, focused on the wives of veterans with PTSD. Data collection was carried out using a non-random sampling method. Data for this research were gathered using demographic and self-efficacy questionnaires. The demographic questionnaire collected information on the age of the veteran's spouse, duration of marriage, percentage of military service, education, and occupation. A total of 30 participants were divided into intervention and control groups. The independent t-test revealed a significant difference between the control and spiritual self-care groups after the intervention (P<0.01), whereas no significant difference was observed before the intervention (P=0.36). Additionally, the paired t-test indicated no significant difference in the control group before and after the intervention (P=0.89). Still, a significant difference was found in the spiritual self-care group (P<0.01). After adjusting for the pre-test effects, it was demonstrated that the spiritual self-care model significantly impacts the self-efficacy of veterans. It is estimated that approximately 85% of the changes in self-efficacy can be attributed to the spiritual care intervention (Eta=0.85, P<0.001). This research demonstrated that spiritual self-care enhances self-efficacy in veterans' wives. As a psychological variable, self-efficacy is crucial in managing life crises and stresses. Spiritual beliefs serve as an effective strategy for coping with challenges and significantly improve the self-efficacy of veterans' wives.
Challenges of work migration for nurses
Authors:   Far Eastern Federal University, Vladivostok, Russia, Mohammadi Matin
Published: October 2024

According to the World Health Organization, the global healthcare system is increasingly challenged by an aging population and the rising burden of chronic diseases [1]. Additionally, European societies are rapidly becoming multicultural, which presents new challenges and opportunities for communities receiving migrants [2]. Based on the International Centre on Nurse Migration report, the world needs nearly 6 out of 10 million new nurses, turning the nursing shortage into a significant global challenge [3]. With the growing elderly population and the prevalence of chronic diseases, the demand for healthcare professionals, especially nurses, has never been higher [1]. As a result, many Western countries have turned to recruiting nurses from other nations, leading to increased nurse migration, which has now become a global issue [4]. The professional threats associated with nurse migration include communication barriers, heavy workloads, and high levels of responsibility [1]. Moreover, the lack of language proficiency among migrant nurses is considered the biggest obstacle in communicating with patients and healthcare teams [5]. Low wages and high workloads are also significant challenges for migrant nurses [3]. Additionally, recruitment agencies exploit nurses, another issue faced in foreign countries [6].

Published: October 2024

This research paper investigates the application of window-based refresh strategies to enhance the performance of data extracts in large-scale data management systems. Traditional extract, transform, load (ETL) processes often struggle with the increasing volume and velocity of data in modern environments. Window-based refresh strategies offer a promising solution by focusing on specific subsets of data during each refresh cycle. This study examines various window-based techniques, including time-based, size-based, and hybrid approaches, and evaluates their effectiveness in improving extract performance. Through extensive analysis and empirical testing, we demonstrate that window-based strategies can significantly reduce processing time and resource utilization while maintaining data consistency and integrity. The paper also explores optimization techniques, challenges, and future research directions in this field.

Análisis del restablecimiento de la respuesta usando reforzadores cualitativamente diferentes
Authors:   Universidad Nacional Autónoma de México, Dionisio Olga M. , Roca Alicia ,   Universidad Nacional Autónoma de México
Published: October 2024

El restablecimiento ocurre cuando una respuesta previamente eliminada recurre como consecuencia de entregar reforzadores independientes de la conducta. Típicamente los experimentos constan de tres fases; 1) se entrena una respuesta, 2) se extingue la respuesta, y 3) se entregan reforzadores independientemente de la conducta. El propósito del estudio fue comparar los efectos de entregar el mismo reforzador y reforzadores cualitativamente diferentes en las Fases 1 y 3 sobre el restablecimiento de las presiones a la palanca y de los patrones temporales de respuesta en ratas. En la Fase 1, las respuestas se reforzaron conforme a un programa de intervalo fijo 30 s. En la Fase 2, las respuestas se extinguieron. En la Fase 3, se entregaron reforzadores independientemente de la conducta de los sujetos. En condiciones sucesivas, se entregó el mismo reforzador o reforzadores diferentes en las Fases 1 y 3. El restablecimiento de la respuesta ocurrió en las dos condiciones, sin embargo, el grado de restablecimiento fue mayor cuando se empleó el mismo reforzador. Los patrones temporales de respuesta se restablecieron únicamente en la condición del mismo reforzador. El restablecimiento de la conducta al emplear diferentes reforzadores podría constituir un caso de renovación de la respuesta.
Acumulación de comida en ratas con una operante libre
Authors:   Universidad Nacional Autónoma de México, Flores R. Andrea , Bruner Carlos A. ,   Universidad Nacional Autónoma de México
Published: October 2024

La investigación anterior sobre la acumulación de comida en ratas ha usado diferentes situaciones de ensayo discreto. El descubrimiento de que la variable activa en la acumulación es la magnitud de reforzamiento demorado hizo evidente la relación entre la acumulación y los estudios clásicos y los modernos sobre demora de reforzamiento. Dado que los estudios modernos sobre demora han usado operantes libres, este trabajo intentó replicar la típica función creciente entre la respuesta de procuración de comida y la duración de la demora empleando una operante libre. Se expuso directamente a tres ratas a un programa tándem modificado intervalo fijo (IF) 30 s tiempo fijo (TF) de 0, 2, 4, 8, 16 o 32 s. El tándem se adaptó para que el número de presiones a la palanca durante el IF entregara el mismo número de bolitas al finalizar el TF. Se encontró que la tasa global de respuesta durante las sesiones (y el número de bolitas) aumentó monotónicamente al alargar la demora de reforzamiento. Estos datos muestran que la acumulación de comida no está limitada a situaciones de ensayo discreto. Además, que el fenómeno de acumulación contradice la presunta universalidad de la disminución en la respuesta en gradientes de demora de reforzamiento.

Published: October 2024

Este experimento tuvo como propósito principal evaluar la condición de habilitación lingüística del aprendizaje comprensivo con modos reactivos combinados no redundantes en una tarea en que debían cumplirse criterios de congruencia utilizando la propiedad conmutativa de la suma. Adicionalmente, se intentó probar si existían diferencias ante una misma prueba respondiendo con modos activos distintos (señalando, hablando, escribiendo), así como determinar si la posible habilitación obtenida podía transferirse a tareas con otros criterios de ajuste (diferencialidad, efectividad, precisión y coherencia) respondiendo con el mismo modo activo de Señalar. Participaron 12 estudiantes de 5º de primaria distribuidos en 3 grupos de comparación. G1 únicamente observó la demostración automática de la solución a la tarea; G2 observó y adicionalmente escuchó una explicación y un ejemplo extra-situacional sobre la tarea; G3 observó y leyó la misma información presentada a G2. Los resultados mostraron niveles de habilitación más altos en el grupo que observó y leyó (G3); indicaron también un alto grado de transferabilidad de la habilitación ante tareas con otros criterios de ajuste. Sin embargo, se encontraron diferencias importantes entre algunos participantes respondiendo con modos activos distintos. Se concluye principalmente sobre la necesidad de evaluar si la operacionalización tecnológica de los modos activos jugó algún papel determinante en estos resultados.

Published: October 2024

A aprendizagem da relação condicional emergente no responder por exclusão nem sempre ocorre. Se o responder por exclusão é um fenômeno robusto, as evidências da aprendizagem não vêm sendo observadas quando diferentes tipos de sondas foram empregados e raramente as sondas de discriminação foram adotadas com esta finalidade. Este estudo verificou o estabelecimento de relações entre palavras e objetos em sondas de discriminação, que avaliaram a relação modelo-S+, após a emergência da relação condicional no responder por exclusão, para sete crianças, entre 18 e 22 meses. As relações condicionais de linha de base eram compostas por nomes e respectivos objetos. A emergência de relações condicionais foi verificada em sondas de exclusão e o estabelecimento das relações emergentes foi testado em sondas de discriminação, com follow-up. Seis em sete crianças responderam por exclusão. Uma participante respondeu aos estímulos previstos nas sondas de discriminação após uma tentativa de exclusão e nove tentativas subsequentes, similares à tentativa de exclusão, e no follow-up entre dois e seis dias. As respostas às sondas de discriminação sugeriram o estabelecimento das duas relações condicionais. Os resultados sugerem que as sondas de discriminação podem ser utilizadas para verificar a aquisição de novas relações nome-objeto (medida de aprendizagem).

A Análise do Comportamento tem avançado no estudo de relações de metacontingências para explicar fenômenos culturais. Nesse sentido, o presente estudo teve como objetivo verificar os efeitos da aplicação de um procedimento análogo de reforçamento negativo sobre a recorrência de culturantes em duas microculturas de laboratório. Duas microculturas de laboratório de 3 participantes foram expostas a um delineamento ABAB e BABA, respectivamente. A tarefa consistia de escolhas de linhas em uma matriz 10x10, com linhas coloridas e numeradas. Os dados sugerem a seleção de um culturante como resultado de um procedimento análogo de reforçamento negativo. As microculturas foram afetadas diferentemente pelo contato com a metacontingência, uma teve a produção de consequências individuais reduzida após o contato com a metacontingência, e outra manteve a produção de consequências individuais durante toda a sessão experimental. Embora a literatura aponte para uma possível diferença entre efeitos de procedimentos análogos de reforçamento positivo e negativo sobre a seleção de culturantes, não foram encontradas evidências disso no presente estudo. Contudo, tendo o presente estudo tratado apenas da seleção de culturantes, é sugerida a utilização do atual procedimento como condição inicial de estudos que procurem explorar a transmissão de culturantes utilizando um análogo de reforçamento negativo cultural.

Published: October 2024

Pessoas com Deficiência Intelectual (DI) ou com Transtorno do Espectro do Autismo (TEA), muitas vezes apresentam dificuldades na aquisição de linguagem, incluindo o repertório intraverbal. Este déficit pode estar relacionado aos antecedentes verbais que, na maioria das relações intraverbais, envolve discriminações condicionais verbais, em que uma resposta está sob controle de dois ou mais estímulos verbais. O presente estudo teve como objetivo investigar o repertório intraverbal de indivíduos com DI, TEA e desenvolvimento típico. Foi realizada a tradução e a aplicação de um protocolo de teste de relações intraverbais, originalmente em inglês. Os participantes foram 26 indivíduos com DI, 23 com TEA e 30 com desenvolvimento típico. O protocolo traduzido, com 80 perguntas, foi administrado individualmente com cada participante. Cada pergunta era apresentada sem que houvesse tempo limite para o participante responder. As respostas eram registradas em protocolo específico. Os resultados replicam dados encontrados anteriormente e indicam que o desempenho torna-se menor conforme as perguntas tornam-se mais complexas (de discriminações simples a discriminações condicionais).

O presente estudo propõe a utilização da modelação em vídeo no ensino de pares típicos em uma Intervenção Mediada por Pares (IMP) como estratégia para promover habilidades sociais em crianças com Transtorno do Espectro Autista (TEA). Participaram do trabalho duas crianças de seis anos diagnosticadas com TEA e seis crianças com desenvolvimento típico. Cada grupo de quatro crianças, incluindo um participante com TEA e três pares típicos, realizou sessões de brincadeira livre durante quinze minutos. Foram contabilizadas as respostas de “iniciar” e “responder interação”. Antes de cada sessão de intervenção, os pares típicos assistiram vídeos apresentando estratégias para interagir com seus colegas com TEA. A intervenção foi planejada em sistema de linha de base múltipla entre pares típicos. Os resultados demonstraram aumento no número de respostas de “iniciar interação” realizadas por pares típicos e tendência de aumento no “responder interação” das crianças com TEA. Interações envolvendo brinquedos também foram mais frequentes. Houve, entretanto, variação individual e ao longo das sessões. Além disso, verificou-se maior concentração de interações nos minutos iniciais da sessão, logo após a exibição dos vídeos. Esses resultados indicam que a modelação em vídeo pode ser uma estratégia efetiva para o ensino de pares típicos em IMPs.

Authors: Mahfuza Rahat Oishy  , Sharmila Siddika Mila
Published: October 2024

This paper focuses on the issues of racism and segregation in Maya Angelou’s selected poems. As an African American, Maya Angelou in her poems and autobiographical novels demonstrates the historical, social and economic condition of her community, especially till the 1970’s. To argue on these grounds, power structure between the white and the black, or African American is also important to discuss. In this paper, six poems of Maya Angelou which are “Still I Rise”, “Caged Bird”, “Alone”, “Harlem Hopscotch”, “Phenomenal Woman” and “My Guilt” will be discussed and analyzed to discover and rediscover the themes of racism and segregation. So, this paper examines the historical reality of Maya Angelou’s community, important features, facts and information found in her poetry, along with the way of segregation in a racist society. Simultaneously, this paper explores the socio-economic context of the blacks as a base for racism and segregation and the apparent mentions of racism and segregation in Maya Angelou’s poems.
The Postmodern Individual in J.M. Coetzee’s Novels: Exploring Issues of Identity, Representation, Intertextuality, and the Self
Authors: Nader Fatima , El Bakal Mohamed
Published: October 2024

This paper explores the postmodern elements in J.M. Coetzee’s novels, focusing on his treatment of themes such as representation, intertextuality, fragmentation, and ambiguity. Through a close examination of works like Foe, Waiting for the Barbarians, and In the Heart of the Country, the study demonstrates how Coetzee disrupts conventional narrative structures and challenges traditional ideas of truth and reality. The analysis delves into how Coetzee’s novels reflect the postmodern rejection of a singular truth, emphasizing the plurality of perspectives and interpretations. The paper also highlights Coetzee’s use of fragmented narratives to depict the instability of identity and meaning in a chaotic world. Furthermore, it explores Coetzee’s conscious deployment of intertextuality, where his works engage with and reinterpret previous literary texts, reinforcing the postmodern view that no text is entirely original. The paper ultimately argues that Coetzee’s fiction exemplifies postmodern techniques, inviting readers to actively engage in constructing meaning and questioning established narratives.

Authors: Riea Kashfi Barua , Chakma Rocky
Published: October 2024

The highly efficient CIGS thin-film solar cell is numerically investigated in this paper using solar simulator software wxAMPS (Analysis of Microelectronic and Photonic Structures). WxAMPS is a customized simulation software package mainly used for photovoltaic cells, which supports quick data input and enhanced visualization with its improved user interface. Copper–indium–gallium–diselenide Cu(In, Ga)Se2 (CIGS) is a semiconductor material with chalcopyrite crystal structure that has high conversion efficiency and structural stability. CIGS model- ZnO: Al/ZnO/CdS/CIGS/Mo/substrate is mainly experimental research that considers the physical characteristics, dimensions, and thicknesses of the different layers. The bilayer window and absorber layer with different thicknesses are the critical factors that influence solar cell performance. The bilayer window concept can assist in reducing the loss at the window layer. In this paper, through the numerical simulation, the highest conversion efficiency was achieved, 18.7%, with an optimum bandgap of 1.12 eV with 3000 nm thickness of the absorber layer under AM 1.5G.
Reinforcement Learning and PD Control Based Trajectory Tracking for a Quadcopter UAV
Authors: Karahan Mehmet
Published: October 2024

Nowadays, quadcopter unmanned aerial vehicles (UAV) are used in a wide variety of areas, such as reconnaissance and surveillance, firefighting, search and rescue, agricultural spraying, cargo transportation, photography, and mapping. The use of quadcopters in a very wide area makes their trajectory tracking control important. In order for quadcopters to perform their duties successfully, they must be able to follow the given trajectory with the least error. In this study, the quadcopter’s trajectory tracking under random noise is provided by an algorithm based on reinforcement learning and a proportional derivative (PD) controller. Modeling, simulations, and reinforcement learning algorithms were carried out using the MATLAB program. Simulations were made under noise for the x, y, z trajectories and roll, pitch, and yaw angles of the quadcopter. A detailed time response analysis was performed by obtaining rise time, overshoot, and settling time data. It has been observed that the references given were successfully followed thanks to the algorithm based on reinforcement learning.
Language Preservation through Popularization of Regional Indian Music: A Data-Driven Approach
Authors: Goel Pramit
Published: October 2024

The increased global connectivity due to internet penetration has resulted in the dominance of international languages and the decline of regional languages. To help preserve these languages, this study identifies the non-native regions in India that offer the most promising opportunities for expanding the popularity of music for each of the 14 regional languages. It analyses the audio features of 41,000 songs from 14 Indian languages on Spotify, employing two approaches – clustering algorithms and Random Forest Regressors. An overlap between the regions identified by both methods for any given language is considered a robust result, providing greater confidence in the results. The results show that while geographical proximity is a significant factor in determining non-native market fits for the music of a given language, alignment in preferences of audio features driven by cultural similarities plays an integral role as well. The findings have important implications for music industry stakeholders, including artists, management, digital platforms, and governments, who can leverage this data to devise strategies to expand the reach of regional music. This includes designing targeted marketing strategies, fostering cross-regional artist collaborations, and optimizing content recommendation algorithms, among others.

Published: October 2024

La presente investigación sitúa a los estudiantes como sujetos de análisis, concibiéndolos como sujetos sociales, con voz y vida propias. El objetivo del estudio fue analizar las experiencias socioemocionales que han construido las y los estudiantes de la Licenciatura en Ciencias de la Educación del Instituto de Ciencias de la Educación de la Universidad Autónoma “Benito Juárez” de Oaxaca, a fin de comprender su impacto durante su trayecto formativo. Se desarrolló desde una perspectiva cualitativa, situando como eje rector analítico a la fenomenología, se emplea el recurso narrativo mediante el cual se recuperan las experiencias vividas de los estudiantes universitarios. La técnica empleada fue la entrevista semiestructurada, aplicada a 301 estudiantes inscritos. Los datos empíricos se sistematizaron a través del software Atlas.ti. Se obtuvieron interesantes registros narrativos integrados en la unidad de análisis “tipos de experiencias socioemocionales”; se construyeron tres categorías analíticas: experiencias escolares, experiencias extraescolares y experiencias de relación con el otro; en ellas se dio cuenta de las voces de los estudiantes, comprendiendo de una manera compleja, humana y situada la significación que confieren los estudiantes universitarios a las experiencias socioemocionales como resultado de las intersecciones construidas entre lo individual y social de la condición estudiantil.

Published: October 2024

El presente artículo muestra los hallazgos de un análisis cualitativo de contenido que tuvo como finalidad explorar la configuración discursiva de la propuesta curricular en la Nueva Escuela Mexicana (NEM), formulada desde los documentos abordados en las sesiones de los colectivos escolares en los ciclos 2019-2020 y 2022-2023. Para ello planteamos tres objetivos específicos: primero, identificar y analizar los conceptos centrales de las dimensiones generales –social amplia, institucional y de aula-didáctica– de la propuesta curricular; segundo, identificar los sujetos de desarrollo curricular enunciados en los documentos; tercero, identificar y analizar las demandas hacia los docentes, formuladas desde los textos examinados. Los hallazgos muestran que en el primer periodo se sentaron las bases para la institucionalización de la NEM mediante la socialización del marco curricular y del establecimiento de lineamientos de gestión. En 2022-2023 los documentos acompañaron un proceso de formación dirigido a la apropiación del plan de estudio por parte del profesorado, el seguimiento del codiseño y la integración curricular, así como la construcción de los programas analíticos. Finalmente, consideramos que el proyecto educativo sugiere un cambio en el rol de los docentes como sujetos sociales del currículo formal.

Authors: Purwaningsih Endang
Published: October 2024

Character education is essential in shaping students’ morals and ethics. This study aims to examine the role of metacognition in character education through a comprehensive literature review. Metacognition, encompassing metacognitive knowledge and skills, enhances the effectiveness of character education by providing strategies such as self-reflection, goal setting, self-monitoring, and self-assessment. The research employs a literature review approach, selecting articles and studies from credible and relevant sources. Data analysis addresses the main question of how metacognitive strategies can be applied to shape students’ morals and ethics. Key findings indicate that metacognition significantly contributes to character education, although challenges such as limited teacher understanding and resource constraints persist. Identified opportunities include developing teacher training programs focused on metacognition and character education and the potential for improved student learning outcomes. This study concludes that integrating metacognition into character education not only enhances the formation of students’ morals and ethics but also offers practical strategies for implementation in schools. Practical recommendations and areas for further research are presented for ongoing development in this field.
