CREATIVE REASONING VS. ALGORITHMIC THINKING: IMPACTS ON STUDENT PERFORMANCE IN MATHEMATICS EDUCATION
Authors: Mucat Geraldine Bagowan
Published: December 2024

In the field of mathematics education, one of the most questions remaining beneath debate is whether students' advancement of scientific thinking and problem-solving is supported more by tackling assignments with given enlightening or by solving them without enlightening. It has been contended, that giving small or no instruction for a numerical errand produces a numerical battle, which can encourage learning. This see in differentiate, tasks in which schedule methods can be connected can lead to mechanical reiteration with small or no conceptual understanding. This consider contrasts Inventive Numerical Thinking, in which understudies must develop the scientific strategy, with Algorithmic Thinking in which foreordained strategies and methods on how to illuminate the assignment are given. Cognitive capability was appeared to have an impact on students' learning for both CMR and AR learning conditions. In any case, math tracks appeared no critical impact.

Published: December 2024

The increased awareness has opened avenues to explore innovative strategies for promoting sustainable consumer behaviour. Notably, artificial intelligence (AI) has become a transformative tool, redefining how consumers interact with products and make purchasing choices. This paper explored AI applications to foster healthy shopping habits in Nigerian retail. The aim of the study was to determine the relationship between AI applications to foster healthy shopping habits in Nigerian retail. The study adopted the survey research design. Based on the research questions, a structured questionnaire was administered to 400 respondents. These copies were analysed, and the hypotheses were tested using the Spearman Rank Order Correlation analytical tool via the SPSS package (version 23.0). Findings revealed a significant relationship between personalization, automation, predictive analytics, and consumer nutritional awareness. The study concluded that the potential for AI applications does not only streamline retail operations but also act as a transformative tool for enhancing consumer shopping habits in Nigerian retail. The study recommended amongst others that Nigerian retailers should prioritize investment in AI-driven solutions like predictive analytics, personalized nutrition recommendations, and automated dietary guidance tools to promote nutritional awareness.
A Corpus-Based Study of Four-Word Lexical Bundles in Chinese and U.S Phd Dissertations
Authors: Chen Min , Abdul Aziz Roslina , Turiman Syamimi
Published: December 2024

Lexical bundles (LBs), which are crucial for smooth language articulation, are deemed a significant unique characteristic in scholarly writing. Many PhD students find that their English academic writing output often falls short of academic expectations compared to native language academic authors in terms of vocabulary sophistication. This study aimed to examine both the functional commonalities and variances in the usage patterns of four-word lexical clusters among Chinese PhD postgraduate EFL students (CH-PhD) and their American counterparts (US-PhD). The study adopted a corpus-based approach, relying on two self-built learner corpora (CH-PhD and US-PhD), and incorporated both quantitative and qualitative data analysis methods. Using AntConc’s N-gram tool, 72 bundles in CH-PhD and 37 in US-PhD were extracted. Findings indicate that Chinese PhD students employed a greater number of four-word word clusters in their academic writings. As for the functional types, Chinese PhD learners are more inclined to use research-oriented bundles to provide descriptions to organise writer’s actions, while native American PhD students are more inclined to use text-oriented bundles to organise the text. Furthermore, the findings illuminate methods to improve the instruction of LBs in China’s academic writing curriculum.
Laicidade em disputa:Centro Dom Bosco versus Católicas pelo Direito de Decidir
Authors: Rosado-Nunes M. J. F. , Bandeira O.
Published: December 2024

Neste capítulo, analisam-se os efeitos das mudanças ocorridas nas últimas décadas no campo religioso brasileiro, alterando, de alguma forma, as relações da sociedade e do Estado com a religião e desta com o Estado,atravessando as discussões em torno de liberdade religiosa, liberdade de expressão e as questões de gênero e sexualidade. E fazendo assim,repensar o significado teórico e político das necessárias relações entre princípios democráticos, Estado de Direito e laicidade. Nessa perspectiva, aborda o caso recente do processo judicial movido pelo Centro Dom Bosco de Fé e Cultura (CDB), uma organização da sociedade civil, contra outra organização, a Católicas pelo Direito de Decidir(CDD), solicitando a esta que deixe de utilizar o termo “católicas”.Este processo judicial permite analisar, a partir de nossas reflexões acadêmicas e de nossa atuação política como militantes feministas, como a laicidade está configurada de distintas formas e está em disputa, e como está articulada com as liberdades públicas de consciência, de expressão e de associação. Do mesmo modo, permite perceber como a igreja e a sociedade civil acionam a Justiça e a ideia de Estado laico de acordo com seus interesses de atuação, ora questionando a Justiça como arena legítima para regular os direitos sexuais e reprodutivos, ora recorrendo a essa mesma arena para defender seus interesses.

The die is cast: Sweden and Finland’s long road to NATO
Authors: Korunova E. V.
Published: December 2024

The accession of Sweden and Finland to NATO came as a shock to many politicians and experts, who until the last moment had believed that these two states would not renounce their traditional neutrality policy. The surprise effect was further enhanced by a remarkable coherence of the countries’ approaches to their membership in the alliance. In order to provide a better understanding of this fundamental shift in Sweden and Finland’s foreign policy courses, this paper examines the evolution of their policies of neutrality during the tribulations of the Cold War. The first section considers the formation of the non-aligned strategies of Finland and Sweden in the aftermath of World War II, which took the form of the so-called Paasikivi-Kekkonen and Unden doctrines, respectively. The author emphasizes that, despite the formal resemblance, the approaches of Sweden and Finland to the neutrality policy varied substantially, since their ambitions and aspirations, as well as their role in the emerging bipolar order were also very different. However, the two states had tended to coordinate their foreign policies already back then and this trend only strengthened in the following decades of the Cold War. The second section shows how the Finnish neutrality model, initially focused on building special relations with the USSR, and a more flexible Swedish non–aligned policy, facilitated convergence of the two states, as well as their cooperation with the Nordic members of NATO. The third section outlines the determinants of the foreign policy transformation of the Northern European neutrals in the aftermath of the Cold War. The author notes that it was the collapse of the bipolar order that paved the way for the comprehensive engagement of Finland and Sweden in the activities of the alliance. It is shown that apart from this cooperation with NATO, a number of regional initiatives involving the Nordic and Baltic countries strengthened foreign policy coordination and contacts between Finland and Sweden. The formal accession of both to NATO thus became only the end point of these processes and the result of the conscious refusal of these countries’ leadership from the original and time-tested non-alignment policy. The consequences of this decision have yet to be assessed by politicians and experts, but one its immediate effect is clear — the emergence of a new security dilemma for the countries of the region.

Authors: Santos Rodrigo Medeiros dos
Published: December 2024

Esta investigação busca compreender, descrever e avaliar o percurso histórico do uso de Tecnologias Digitais de Informação e Comunicação (TDIC) aplicadas ao ensino de Matemática no Brasil. Para tanto, foi desenvolvida uma pesquisa de natureza exploratória e histórico-bibliográfica, com o intuito de coligir e organizar as informações dispersas na literatura sobre o tema. Os principais resultados indicam que as primeiras iniciativas brasileiras no sentido de aliar o uso de tecnologias com a educação ocorreram nos anos 1970, inicialmente nas universidades federais. A década de 1990, entretanto, representou um marco de transição, com a crescente democratização do acesso ao computador e a sua recente chegada às escolas, notadamente as escolas particulares. Porém, a chegada do computador à escola por si só não representou imediatamente uma revolução nos métodos de ensino. Era necessário tanto alfabetizar digitalmente os alunos, quanto formar professores aptos ao trabalho com as tecnologias digitais. Neste sentido, o grande entrave foi adequar os cursos de formação inicial à nova realidade. Esta investigação enumera dois principais desafios e perspectivas futuras para área, a saber: i) as novas potencialidades da inteligência artificial e as suas aplicações ao ensino de Matemática; ii) a formação inicial de professores para o trabalho com as tecnologias digitais, que segue historicamente como um dos maiores entraves para a área, uma vez que os contantes avanços tecnológicos e as novas diretivas curriculares em frequente mutação demandam constantes atualizações na grade curricular das Licenciaturas.

Os jogos eletrônicos são artefatos amplamente presentes na sociedade, alcançando, ao longo dos anos, pessoas de várias idades e transformando nossas relações com a tecnologia por meio das interações que temos com suas histórias e ambientações. Tratam-se de elementos que, a partir da mediação docente, são capazes de potencializar a construção do conhecimento científico através da representação de diferentes espaços e tempos, podendo ser utilizados em contextos educacionais que envolvem a interação entre pessoas e tecnologia. Neste artigo, nosso objetivo é analisar como os jogos eletrônicos representam o tempo histórico e o espaço geográfico em uma aproximação com a Base Nacional Comum Curricular (BNCC). Para isso, revisamos os conceitos relevantes dos componentes curriculares de História e Geografia e examinamos a presença desses conceitos nas narrativas, imagens, personagens e cenários dos jogos Assassin’s Creed Origins e Horizon Zero Dawn. Por fim, concluímos que esses jogos são artefatos que nos conectam a diferentes épocas e lugares, permitindo-nos perceber nossas ações no passado e presente bem como refletir criticamente sobre o futuro.
Analysis of recurrence of risk factors after transcatheter bronchial artery embolization for hemoptysis
Authors: Dong Yanchao , An Jianli
Published: December 2024

BACKGROUND:

As a proven and preferred technique for hemoptysis, bronchial artery embolization (BAE) cannot avoid the possibility of postoperative recurrence; however, few studies have examined the causes of hemoptysis recurrence after BAE.

OBJECTIVES:

Identify the risk factors for hemoptysis recurrence after BAE treatment.

DESIGN:

Retrospective

SETTING:

Tertiary training and research hospital

PATIENTS AND METHODS:

A retrospective analysis was conducted on 406 patients with hemoptysis, 55 patients who developed with recurrent postembolization hemoptysis, covering the period from January 2011 to January 2021. Single factor analysis and multiple factor logistic regression were used to analyze high-risk factors for hemoptysis recurrence.

MAIN OUTCOME MEASURES:

The incidence and risk factors for recurrence hemoptysis associated with transcatheter BAE.

SAMPLE SIZE:

406 patients

RESULTS:

Multivariate logistic regression analysis showed that preoperative computed tomography angiography (CTA) (odds ratio [OR]: 0.052, 95% CI: 0.012–0.225), tumor-related hemoptysis (OR: 20.753, 95% CI: 6.778–63.545), pleural thickening (OR: 3.168, 95% CI: 1.081–9.286), and bilateral lung lesions (OR: 8.442, 95% CI: 2.449–29.101) had a statistically significant impact on the recurrence of hemoptysis after BAE.

CONCLUSIONS:

Preoperative CTA serves as a protective factor against hemoptysis recurrence, whereas tumor-related hemoptysis, pleural thickening, and bilateral lung diseases are significant risk factors for hemoptysis recurrence following interventional therapy.

LIMITATIONS:

This was a retrospective analysis of a single center with a small sample, which may have a certain degree of recall bias when collecting data, thus, reducing the reliability of the results.

Published: December 2024

BACKGROUND:

Postoperative complications of colorectal cancer surgery contribute to increased morbidity and mortality in patients.

OBJECTIVES:

Investigate the role of biochemical markers in serum and peritoneal fluid in the development of postoperative complications in patients with enteral anastomosis.

DESIGN:

Prospective.

SETTING:

University hospitals.

PATIENTS AND METHODS:

The studied population consisted of patients who underwent surgical treatment with created anastomosis or Hartmann's resection from April 2022 to April 2024, conducted at the Clinical-Hospital Center Kosovska Mitrovica and the University Clinical Center Kragujevac. Spearman's correlation coefficient (r
s
) was used to test associations between categorical variables.

MAIN OUTCOME MEASURES:

Lactate, albumin, lactate dehydrogenase, and IgA antibodies were monitored as predictors of anastomotic dehiscence and general postoperative complications.

SAMPLE SIZE:

52

RESULTS:

The concentration of lactate in the drain fluid on the third postoperative day was statistically significantly higher in patients who did not develop anastomotic dehiscence (
P
=.006). The concentration of IgA antibodies in the drain fluid on the third and fifth days post-surgery showed a moderate negative correlation with lactate concentration (r
s
=-.670,
P
=.012; r
s
=-.577,
P
=.039), repectively. There was a significantly higher concentration of albumin in the drain fluid on the third day post-surgery in patients who developed dehiscence (
P
=.040), and on the seventh day post-surgery in those who did not develop dehiscence (
P
=.001). The concentration of LDH on the third day in the drain fluid after surgery was statistically significantly higher in patients who did not develop dehiscence (
P
=.020). There was a statistically significant difference in lactate concentration in the drain fluid on the third (
P
<.001) and fifth days (
P
=.041) post-surgery, as well as in albumin concentration on the third day post-surgery (
P
=.024) with respect to the development of general postoperative complications.

CONCLUSION:

This study revealed significant differences in the concentrations of lactate, albumin, and LDH in the drain fluid on the third and fifth days post-surgery with respect to the development of complications. These results suggest that monitoring these markers may help in the early identification of patients at risk of complications such as dehiscence.

LIMITATIONS:

Limited literature on specific aspects of this study, including the absence of a control group, small sample size, and two-center study.

Published: December 2024

Despite applying conventional predictive methodologies to obtain genomic insights, predicting drug sensitivity for healthcare organizations in the USA remains a daunting challenge. Cancer is a highly dynamic, adaptive disease tumor cells have repeatedly shown the capability to evolve mechanisms whereby therapeutic interventions can be evaded. Besides, one genomic alteration seldom predicts drug sensitivity. This research project aimed to address the challenges of predicting drug sensitivity by leveraging the GDSC dataset, an extensive resource connecting genomic profiles of cancer cell lines with their sensitivity to a wide range of anti-cancer drugs. This research's key focus was identifying robust genomic markers, including any specific mutations, gene expression patterns, or epigenetic modifications associated with drug sensitivity or resistance. Advanced machine learning and statistical methods were utilized by the predictive models to analyze complex relations that may exist between different genomic alterations and their drug sensitivity. The dataset used for this research project was derived from the Kaggle website. This dataset was compiled by the research project Genomics of Drug Sensitivity in Cancer collaboration between the Sanger Institute in the United Kingdom and the Massachusetts General Hospital Cancer Center in the United States. In their investigation, there was a massive screening of human cancer cell lines with a wide range of anti-cancer drugs. Data collection was performed by large-scale screening of diverse anti-cancer drugs against human cancer cell lines of various types. Cell viability was measured using the Cell-Titer-Glo assay following 72 hours of drug treatment. Several machine learning models were deployed, namely, Random Forest, Linear Regression, and XG-Boost, which exhibited specific strengths. Specific performance metrics used included MSE, RMSE, MAE, and R². As the statistics indicate, among the three models, Random Forest stands out and performs the best on this dataset across all metrics. A smaller value of MAE, MSE, and RMSE signifies that it provided the best forecast for the target variable. It also gave the highest R-squared value. Application of drug sensitivity prediction analysis in cancer can provide an overview of the mechanisms that underlie both tumor response and resistance by investigating the model predictions. The proposed predictive models have the potential to make significant impacts on clinical decision-making in cancer therapy. Predictive models derive informed decisions regarding a patient's risk of recurrence of disease, their response to certain therapies, and their prognosis based on complex clinical and genomic data.

Published: December 2024

The use of tobacco products poses a significant public health challenge, affecting approximately 1.1 billion smokers and is expected to rise. In Kenya, 37% of university students in Nairobi County were engaging in Shisha smoking. Despite the growing prevalence of Shisha smoking among the youth, studies specifically focusing on reasons for its use in Kenya remain limited. This study aimed to establish individual factors influencing Shisha smoking among students in tertiary institutions in Kisumu County. The study used a cross-sectional study design. The target population was 26,384 students aged 18 - 24 years. The sample size obtained was 398 students, which was computed based on a known prevalence of 37%. The study targeted tertiary institutions: Maseno University, Uzima University College, Great Lakes University of Kisumu, Kenya Medical Training College-Kisumu, and Kisumu National Polytechnic. Institutions were purposely sampled, and each sample was determined using population proportionate to size, stratified sampling was employed to obtain students across all academic years and simple random sampling was used to achieve the sample size. The reliability of the questionnaires was assessed using a Cronbach’s Alpha with a score of more than 0.7 for all the objectives, and data collection was conducted by trained research assistants using pre-tested questionnaires. Data analysis was conducted using SPSS version 25. Frequencies and percentages were used to determine the prevalence and reasons for Shisha smoking. Cramer’s V and Chi-square p-value <0.05 were used to establish associations. Curiosity (26.6%), pleasure-seeking (21.8%) and the appeal of flavours (19.4%) of the students led them to smoke shisha. There was no significant association between self-esteem and shisha smoking (p-value 0.407). The study concludes that curiosity and social factors: as the appealing and stylish nature of flavoured Shisha were identified to be the motivators for tobacco smoking among the students the study recommends that there should be social and behavioural change communication strategies for promoting healthy Shisha, conducting support groups and working with parents in sensitisation of education initiatives on Shisha smoking.

New insights into the polar ozone and water vapor, radiative effects, and their connection to the tides in the mesosphere-lower thermosphere during major Sudden Stratospheric Warming events

Published: December 2024

Abstract. We examine the variability of diurnal (DT), semidiurnal (SDT), and terdiurnal (TDT) tide amplitudes in the Arctic mesosphere and lower thermosphere (MLT) during and after sudden stratospheric warming (SSW) events using meteor radar data at three polar-latitude stations: Sodankylä (67.37° N, 26.63° E), Tromsø (69.58° N, 19.22° E), and Svalbard (78.99° N, 15.99° E). By combining tidal amplitude anomalies with trace gas variations, induced by large-scale dynamical changes caused by the breaking of planetary waves, this study provides new observational insights into the variation of ozone and water vapor, transport, and tides at polar latitude. We use short-wave (QRS) and long-wave (QRL) radiative heating and cooling rates simulated by the WACCM-X model to investigate the roles of polar ozone and water vapor in linking mesospheric tidal variability during SSWs in the polar regions. Our analysis reveals distinct tidal responses during SSW events. At the onset of SSWs, a significant negative anomaly in TDT amplitudes is observed, with a decrease of 3–4 m/s, approximately 15–20 % change compared to mean TDT tide. Meanwhile, SDT shows a positive anomaly of 10 m/s, with changes reaching up to 40 %, indicating an enhancement of tidal amplitude. The DT amplitude exhibits a delayed enhancement, with a positive amplitude anomaly of up to 5 m/s in the meridional wind component, occurring approximately 20 days after the onset of SSWs. A similar, but weaker effect is observed in the zonal wind component, with changes reaching up to 30 % in the zonal component and 50 % in the meridional wind component. We analyzed the contributions of ozone and water vapor to the short-wave heating and long-wave cooling before, during, and after the onset of SSW events. Our findings suggest that the immediate responses of SDT are most likely driven by dynamical effects accompanied by the radiative effects from ozone. Radiative forcing change during SSW likely plays a secondary role in DT tidal changes but appears to be important 20 days after the event towards the spring transition. Water vapor acts as a dynamical tracer in the stratosphere and mesosphere but has minimal radiative forcing, resulting in a negligible impact on tidal changes. The interaction between dynamic processes and the transport of radiatively active gases is important for explaining the observed tidal variability during SSW events. This study provides the first comprehensive analysis of mesospheric tidal variability in polar regions during SSWs, exploring and linking the significant role of trace gases and radiative effects in modulating tidal dynamics.
Boosters in academic discourse: contrastive analysis concerning their use in theses from the fields of social sciences and natural sciences
Authors: Álvarez-Gil Francisco J. , Quintana-Toledo Elena
Published: December 2024

In this paper, a corpus linguistics study is performed to analyse the metadiscursive function as boosters of three adverbials, namely absolutely, highly and strongly, in two subcorpora of doctoral dissertations. These dissertations are written in English and were submitted to Spanish universities between the years 2011–2021. The corpus contains more than ten million words overall, with one subcorpus corresponding to the field of the natural sciences and the other to the social sciences. The goals of the present study are twofold. On the one hand, from a quantitative perspective, we aim to determine the number of cases in which these three adverbials play the role of boosters and compare the results of the two subcorpora. On the other hand, we analyse the function of these adverbs as boosters by considering the linguistic elements that co-occur with them and that affect this function, either to reinforce or to mitigate content.
La construcción discursiva en WhatsApp: relaciones demarcativas desde una perspectiva de género
Authors: González-Sanz Marina
Published: December 2024

Este artículo presenta los resultados de una investigación sobre los procesos de demarcación empleados en la construcción de un tipo de comunicación digital: WhatsApp. Para ello, hemos aplicado un tratamiento cuantitativo-cualitativo sobre un corpus de conversaciones efectuadas mediante esta plataforma de comunicación, constituido por más de 22 000 mensajes, sobre el que se ha aplicado la metodología de la lingüística pragmática. Los resultados muestran que, aunque aparecen recursos propios de la conversación cara a cara, tales como fórmulas de saludo o marcadores discursivos, resulta más rentable hablar en términos de par adyacente iniciativo-reactivo, porque los usuarios no parecen querer iniciar una conversación con fines transaccionales en la mayoría de los casos, sino simplemente mostrar una información al receptor para incitarle a reaccionar. Esto se formaliza mediante recursos verbales, multimodales o una combinación de ambos, siendo este último el esquema más frecuente en el corpus. Asimismo, hemos llevado a cabo una aproximación desde la perspectiva de género, que nos ha permitido demostrar que las mujeres presentan una preferencia por emitir una intervención reactiva pospuesta sobre la intervención anterior antes de abrir un tema nuevo, lo que puede atribuirse a la tendencia tradicionalmente atribuida a la mujer del fomento del fin relacional.

Los libros ilustrados de no ficción como estrategia para concienciar hacia los Objetivos de Desarrollo Sostenible: una experiencia con talleres de lectura
Authors: Gutiérrez Molero Salvador , Trigo Ibáñez Ester
Published: December 2024

En los últimos tiempos los sistemas educativos están realizando un notable esfuerzo para concienciar a la ciudadanía sobre la importancia de alcanzar los Objetivos de Desarrollo Sotenible (ODS) de la Agenda 2030. Este estudio aborda la utilidad de los libros ilustrados de no ficción (LINF) en la promoción y concienciación de los ODS, en concreto, los vinculados con el ciudado del medioambiente. En este sentido, la investigación sugiere que los LINF pueden ser una herramienta efectiva en la educación para el desarrollo sostenible. Para ello, se llevó a cabo la dinamización de un LINF a través de un taller de lectura para generar conciencia entre estudiantes de sexto de Educación Primaria (EP) respecto a los ODS. Así, se utilizó el LINF SOS. Monstruos verdaderos amenazan el planeta con el objetivo de vincular la promoción lectora con la concienciación y reflexión crítica sobre los ODS a través de actividades manipulativas, debates y búsqueda de información fiable. Para la correcta dinamización del LINF se ha seguido la dinámica de acompañamiento a la lectura propuesta en investigaciones precedentes y se ha utilizado una parrilla de observación. Los resultados indican que los/las estudiantes mostraron una actitud positiva hacia la lectura y el aprendizaje de los temas relacionados con los ODS abordados en los talleres. Además, demostraron haber adquirido conocimientos y vocabulario específico que no poseían previamente al desarrollo de los talleres. Esto nos hace concluir que, teniendo en cuenta la experiencia realizada, se aprecia la evidente capacidad de ciertos LINF de funcionar como un recurso efectivo para la promoción del pensamiento crítico, para lo cual es necesaria una selección cuidada y una planificación sólida y coherente.

La escritura creativa de textos literarios es una de las competencias que el alumnado debe desarrollar como parte de su formación lingüística y litrearia, pero también como instrumento de expresión artística de su identidad personal y social. Pese a ello, habitualmente estos contenidos son objeto de una enseñanza desestructurada (tal como reflejan las propuestas simples e imprecisas de los libros de texto de Lengua Castellana y Literatura), lo que imposibilita que gran parte del alumnado pueda desarrollarlos con éxito. Para mejorar el proceso de enseñanza-aprendizaje de la escritura creativa hemos diseñado “Escritores de mapa”, una situación de aprendizaje centrada en la elaboración de cuentos literarios y dirigida al primer ciclo de la ESO, que se basa en la estructuración y división en tareas del proceso de escritura creativa, de modo que cualquier alumno o alumna, independientemente de sus necesidades y capacidades, pueda narrar su propio cuento. Esta situación de aprendizaje se sustenta en la aplicación práctica de algunos de los modelos narratológicos más conocidos, como la teoría actancial de Greimas, el llamado “viaje del héroe” de Campbell, las teorías sobre el narrador y la focalización de Genette, las tipologías de personaje planteadas por Forster o el concepto de cronotopo de Bajtín. Nuestra situación de aprendizaje, basándose en la estrategia didáctica del modelado, explicita los procesos de creación que desarrollan los escritores, para que el alumnado realice gradualmente tareas hasta obtener un objeto, el cuento, como resultado de un proceso de aprendizaje significativo. Pretendemos así que la escritura creativa se convierta en un instrumento esencial para la formación lingüística, cultural, artística y emocional de nuestro alumnado.

This research aims to analyze school mathematics teaching materials from a practical perspective, where the researcher seeks to understand how students engage with the content presented in the teaching module. The concept of praxiology is a fundamental construct of the Anthropological Theory of Didactics (ATD). Teaching materials serve as empirical sources that can reveal the knowledge to be taught during didactic transposition. Through document study (in phenomenological design qualitative research) of the school mathematics teaching materials based on the Merdeka Curriculum, the results obtained are: (1) The task component in the material of direct and inverse proportions uses operational techniques and includes standalone tasks for students to complete; (2) The technique component is appropriate because the information presented in each session has continuity; (3) The technology component is not yet fully aligned, thus requiring improvements and enhancements in the development of information and communication technology-based learning media, and (4) The theory component aligns with a constructivist theory where students can build knowledge based on their individual experiences.

The current reality is that the employers of labour no longer have adequate space to accommodate the teaming population of tertiary institution graduates.  For a few job vacancies that exist, employers look beyond academic qualification. They want graduates who have skills and entrepreneurship orientation that will help their firms to remain profitable and competitive. This paper is an entrepreneurship education that provides graduates/undergraduates of civil engineering in particular and other related disciplines in general, with the necessary skills to appreciate and embrace plumbing as a profession. The aim is to expand the scope of opportunities available to graduates for employability and self-employment after graduation. The paper covers the scope of plumbing, plumbing tools, fittings and fixtures, safety in plumbing, estimates, installation and maintenance work, a step into the plumbing profession, and characteristics of successful plumbers.

Model pembelajaran Numbered Heads Together (NHT) dirancang untuk memberikan kesempatan kepada siswa untuk bekerja sama dan mendukung interaksi interpersonal antar siswa. Aspek yang sangat penting dalam pembelajaran matematika adalah pemahaman konsep. Pemahaman konsep matematika adalah memahami konsep matematika dengan benar, yaitu siswa dapat menerjemahkan, mengartikan, dan menyimpulkan suatu konsep matematika berdasarkan pembentukan pengetahuannya sendiri, bukan hanya sekedar menghafal. Pemahaman konsep, siswa dalam proses pembelajaran dapat mengembangkan kemampuannya, masalah sederhana hingga kompleks dapat dipecahkan oleh siswa dengan menerapkan konsep yang telah dipelajarinya. Salah satu ciri siswa yang dianggap memahami suatu konsep adalah siswa yang mampu memahami suatu konsep dan mampu menjelaskannya kembali dengan menggunakan tata bahasanya sendiri. Jenis penelitian ini adalah quasi eksperimen dengan desain pretest-posttest dengan Simple Random Sampling. Sampel dalam penelitian ini sebanyak 67 siswa kelas VII B dan VII C. Teknik pengujian hipotesis menggunakan uji-t (Independent Sample T-Test) dengan taraf signifikansi 0,05. Hasil analisis data dan pembahasan yang telah dilakukan, dapat disimpulkan bahwa model pembelajaran Numbered Heads Together (NHT) memiliki pengaruh dalam meningkatkan kemampuan pemahaman konsep matematika siswa pada proses pembelajaran matematika.
Effets Des Activités Portuaires Sur L’écosystème Marin Et Côtier A Cotonou (Benin, Afrique De L’ouest)

Les activités portuaires affectent l’écosystème marin et côtier. La présente recherche étudie les impacts des activités portuaires sur l’écosystème marin et côtier. La démarche méthodologique adoptée s’articule autour de la collecte des données, du traitement des données et de l’analyse des résultats. Le traitement des données a été réalisé à l’aide des logiciels SPSS et ArcView. Les résultats de la recherche montrent que les activités portuaires menées dans les six zones (IP1, IP2, IP3, IP4, IP5 et IP6) sont la manutention (98%), l’appareillage (98%), le pilotage (96%), le remorquage (95%), le dédouanement (95%), la pêche artisanale ou industrielle (86%), le magasinage (11%), l’aconage (11%), le relevage (10%), l’entreposage (10%), l’ensachage (9%) et le linguage (9%). Cependant, la manutention (le chargement et le déchargement), le stockage ou l’entreposage, la réparation navale, l’avitaillement génèrent des effets négatifs sur l’environnement. Les impacts des activités de déchargement et d’ensachage ont une portée et régionale, une durée courte et longue, une intensité moyenne, une forte importance et une probabilité d’occurrence moyenne pour le déchargement et une forte probabilité d’occurrence pour l’ensachage. Les incidences des activités de déchargement des hydrocarbures ont une portée locale et régionale, une durée longue, une intensité forte, une forte importance absolue et une forte probabilité d’occurrence. Ainsi, les activités portuaires dans les zones IP1, IP3, IP5 et la zone du port de pêche affectent plus les éléments physiques et humains dans le secteur de recherche. Ce qui engendre plusieurs risques. Les risques de pollution des eaux de mer à partir des navires en rades et/ou en quais au port (28 %), les risques de collisions avec les cétacées (15 %), les risques de déversement accidentel des hydrocarbures au port (37 %) et les risques de déversement accidentel des hydrocarbures sur le littoral (20 %) constituent les risques d’ordre physiques. Ces risques impactent négativement l’écosystème marin et côtier. En outre, il s’observe les risques d’accident de travail en manutentions portuaires (39 %), les risques de contamination chimique (27 %), les risques de congestion et engorgement des rues de Cotonou (18 %) et les risques de collision entre les navires accostant au port et les pirogues des pêcheurs (16 %). Les activités portuaires engendrent des risques humains dans le secteur de recherche.
