Authors: Wati Morina , Silitonga Melva
Published: January 2024

One of the demands of 21st-century learning is optimizing students' problem-solving abilities. The problem-solving ability of students at SMA Negeri 18 Medan is still low. One of the contributing factors to low problem-solving ability is the lack of application of learning devices and models that can activate students and are still teacher-centered. One learning model that can improve problem-solving skills is the guided discovery model. This study aims to analyze students' problem-solving abilities with the implementation of the guided discovery model, the implementation of guided discovery syntax in learning, and student responses to the guided discovery model on excretory system material. This type of research is quasi-experimental research with a pretest-posttest control group design. Sampling using random sampling technique, XI IPA 1 as guided discovery class and XI IPA 2 as direct instruction class. The instruments used consist of essay questions on problem-solving skills, syntax implementation observation sheets, and student response questionnaires. The data obtained are first tabulated, searched for averages, and then analyzed by normality tests and independent sample t-tests. From the results of the independent sample t-test, a significance value of 0.000<0.05 was obtained, indicating that students' problem-solving abilities with guided discovery models and direct instruction models differed significantly. The results showed that the problem-solving ability of grade XI students of SMA Negeri 18 Medan who were taught using the guided discovery model was very high (82.69), the implementation of the guided discovery model syntax with a percentage of 99%, and student responses to learning showed a positive response. Based on the results of the study, the guided discovery model is very appropriate to be used in training the problem-solving ability of grade XI students at SMA Negeri 18 Medan on excretory system material.

The Covid-19 pandemic has changed the way people live, including in the field of education. One of them is WFH (work from home), which causes the learning process to be carried out from home  by online. Students found it difficult to understand the material during online learning which caused learning outcomes to decrease. On the other hand, the development of technology and information can be used so that it is beneficial for education. The advantages of learning video media greatly assist the teacher in conveying the material to be delivered and students better understand the material presented by the teacher. For this reason, it was necessary to develop video-based media for learning the Reproductive System material. The purpose of this study was to analyze the validity, feasibility, and influence of media effectiveness on student learning outcomes based on learning videos on the Reproductive System material. The research steps that were passed used the 4D development model, namely Define, Design, Development, and Disseminate. The research instruments used were student questionnaire sheets, interview sheets, validity sheets, teacher and student response questionnaire sheets, as well as pre-test/post-test sheets. The results of research on the Reproductive System learning video media have met the criteria of being very valid by media experts at 98% and valid by material experts with a score of 72%, the media feasibility score is 94% or very feasible by a questionnaire of teachers and students, and learning video media is effective in improving results student learning on the subject of the Human Reproductive System at SMA Negeri 1 Banjarnegara.

Authors: Asshoumy Syifa Zukhruf , Rahayu Enni Suwarsi
Published: January 2024

Learners need to observe various types of plants to achieve basic competencies in the subject of "Plantae." However, teachers find it challenging to manage learning activities outside the school environment. This research aims to: 1) analyze the influence of three different teaching methods on motivation, classification abilities, and data presentation, and 2) determine the most effective teaching method among the three.This study adopts a quantitative approach, specifically quasi-experimental research, using a non-equivalent control group design. The research population comprises all 10th-grade students in the Science Program (MIPA) at MAN 2 Banyumas, totaling six classes. The sample consists of three classes: X MIPA 2, which uses PlantNet + TGT, X MIPA 3, which uses TGT, and X MIPA 4, which employs discussion. Data collection methods include questionnaires, tests, and observation sheets. Data analysis techniques encompass statistical methods such as normality and homogeneity tests, analysis of variance (ANOVA), and post hoc tests.Based on the ANOVA analysis results for all three classes, a significance value of 0.00<0.05 was obtained. This indicates the impact of the techniques of analyzing images using the PlantNet application and TGT, TGT-based learning, and discussion-based learning on motivation, classification abilities, and data presentation. The least significant difference analysis shows that the PlantNet + TGT class had an average motivation score of 48.20, the TGT class had 36.69, and the discussion class had 28.64. The average increase in classification abilities was 35.25 for the PlantNet + TGT class, 21.18 for the TGT class, and 15.58 for the discussion class. In terms of data presentation abilities, the PlantNet + TGT class had an average increase of 25.02, the TGT class had 17.15, and the discussion class had 11.00. This indicates that the PlantNet + TGT class showed significantly higher improvement compared to the TGT and discussion classes.In conclusion, the study results indicate that all three teaching strategies, including the technique of analyzing images with the PlantNet application and TGT, TGT, and discussion, have an impact on motivation, classification abilities, and data presentation. Among these methods, teaching with the technique of analyzing images with the PlantNet application and TGT resulted in the highest improvement in motivation, classification abilities, and data presentation.

Authors: Sviķe Silga
Published: January 2024

The study provides an insight into the life history of a Baltic German pastor H. Kawall and illustrates his contribution into the knowledge transfer in the field of botany and during the early stages of the Latvian botanical terminology development. Mainly his work “God’s Creatures in the World” („Dieva radījumi pasaulē”, 1860), which is the Latvian translation of the book “Die Naturgeschichte für Kinder und Elementarschüler, oder erster Unterricht über das Mineralreich, Pflanzenreich und Tierreich, mit über 300 kolorierten Abbildungen” (1855), is described in the study. The study discusses translation strategy used by H. Kawall in the Latvian translation when searching for equivalents of German botanical terms and thinking about the addressee of his work. The Latvian botanical terms used in H. Kawall’s work are also analysed in relation to the contemporary botanical terminology. The research of older translations is instrumental in understanding the history of translation; the findings of the research are useful for contemporary translation practice.
Alcohol and Heart Failure

Published: January 2024

Alcohol is the most frequently consumed toxic substance in the world and remains a major global public health issue, with one in three adults consuming it worldwide. Alcohol use is a leading risk factor for disease, contributing to over 60 acute and chronic health conditions, with a particularly complex association with cardiovascular disease. Chronic excessive alcohol consumption is associated with a range of cardiac complications, including decreased myocardial contractility, hypertension, arrhythmias, MI and heart failure. However, low-level alcohol consumption is believed to have a protective effect against ischaemic heart disease and diabetes. In most cohort studies, small to moderate amounts of alcohol consumption have not been linked to heart failure, indicating a threshold effect of alcohol with individual (possibly genetic) predisposition rather than a continuous effect of exposure. This review article explores the potential benefits of alcohol on the heart, the association between alcohol use and alcoholic cardiomyopathy and the epidemiology, clinical correlates and management of alcoholic cardiomyopathy.

The purpose of the article is to present the research results on the land surface temperature change in the frame of the Edu- cational and Professional Program «Ecology and Environmental Protection» developed at the Department of Environmental Sciences at National Aviation University, where the importance of the development of education in the noosphere paradigm is emphasized, as the most integral bio-adequate basis for the interaction of society and the environment in the conditions of today’s challenges. The climate’s change and the land surface temperature, as an integral part of it, are highlighted to tackle the environmental challenges in- cluding those connected with the warfare activities in the country. Development of the remote sensing technique within the framework of the Educational and Professional Program provides students with the opportunity to perform the environment changes assessment due to long-term anthropogenic stress, and also acquire knowledge and skills from the new course of «Adaptation to Climate Change», introduced to strengthen the ability to survive and effectively work and study in conditions of global climate change. The land surface temperature assessment is considered on the examples of the highly technologically loaded areas within the central part of the Ukrainian Shield, in particular the mining area and thermal power plant. Land surface temperature is one of the key features that could represent environmental changes caused by anthropogenic influence, for example, urbanization. It makes land surface temperature an appropriate Earth’s attribute that combines remote sensing and environmental sciences in the sense of environmental education. It is clear, that its influence on environment is intuitive for students and it could be represented using geoinformation systems. Land surface estimation is still a challenging task for non-specialists but its ecological significance makes land temperature mapping useful and important in environmental education.
Análisis de la estructura y evolución de la pobreza en Costa Rica
Authors: Rodríguez Soto Jorge Andrés
Published: January 2024

En Costa Rica la pobreza suele calificarse de estructural, debido a ello, el objetivo de esta investigación es indagar en la estructura de la pobreza y su evolución en el país. Para esto, se recorren las principales concepciones del desarrollo, sus definiciones de pobreza y los indicadores asociados a dichas definiciones. Con esta base, se realiza un estudio de la pobreza en Costa Rica entre 2010-2021, mediante líneas de pobreza e índice de pobreza multidimensional [IPM] (por dimensión e indicador) para cada región de planificación. Se encontró que las asimetrías regionales parecen ser cuantitativas, no cualitativas y las estructuras de privación son similares en las regiones. También, se identifican tres grupos de comportamiento según IPM: la región Central en mejores condiciones, un grupo intermedio y las regiones huetares en peor estado. Seguido, se analizan los datos cantonales para dar una visión coyuntural y corroborar las tendencias. Finalmente, se señala un camino en la atención de la pobreza y elaboración de política pública.

szerológiai vizsgálatok elterjedése, a molekuláris módszerek elérhetővé válása
és a kórokozók szeroepidemiológiai változásai együttesen eredményezték, hogy a

Published: January 2024

Bár a fiúgyermekeket, illetve a fertilis korú férfiakat érintő daganatos
megbetegedések száma világszerte emelkedik, az onkológiai kezelések
eredményessége folyamatosan javul. Ennek következtében jelentősen
felértékelődött a terápiát követő életminőség, és ezen belül, kiemelten, a
nemzőképesség megőrzése. Magyarországon még nem áll rendelkezésre egységes
fertilitásprezervációs szakmai irányelv, betegirányítási rendszer és dedikált
infrastruktúra. A szerzők áttekintik a legfrissebb, irányadó nemzetközi és hazai
szakirodalmi adatokat, és elemzik az érintett szakterületeken szerzett hazai
tapasztalatokat. Ezek ismeretében írnak a fiúgyermekek és a fertilis korú
férfiak onkológiai kezelésének fertilitási kockázatairól, a számukra elérhető
nemzőképességi prezervációs módszerekről, külön kitérve a prae-, illetve
peripubertas-korú fiúkra, valamint a heredaganatok esetén alkalmazható
eljárásokra. Eredményeik multidiszciplináris szemléletet tükröző ismertetése
szakmai ajánlás alapját képezheti. Pubertas utáni életkorú férfiaknál a
fertilitás megőrzésének leghatékonyabb módja az onkológiai kezelést megelőző
spermium-mélyfagyasztás, melyet ejakulációs képtelenség esetén asszisztált
ejakulációs technikák vagy sebészi spermiumnyerés egészíthet ki. Adolescens korú
férfiaknál is lehet spermium-mélyfagyasztás, de ez a mintaadás miatt sokszor
nehézségbe ütközik. Ilyen esetekben, illetve prae- vagy peripubertaskorban
(ejakuláció hiányában) műtéti úton nyert hímivarsejtek vagy spermatogenetikus
őssejtek krioprezervációja végezhető. A spermatogenetikus őssejtek
vonatkozásában a későbbi felhasználás lehetőségei jelenleg experimentális
jellegűek. Speciális megközelítést igényelnek a heredaganatos páciensek.
Megállapításaik alapján egyértelműen szükséges egy egységes szakmai irányelv
szerint, az andrológiai és onkológiai team szoros együttműködésén alapuló
fertilitásprezervációs rendszer kialakítása, amelyhez a megfelelő hely
biztosítása, a humánerőforrás képzése mellett az infrastrukturális,
finanszírozási és jogi környezet megteremtése is szükséges. Tekintve, hogy
hazánkban az onkológiai kezelésre szoruló fiúgyermekek és fertilis korú férfiak
nemzőképesség-megőrzésének mértéke elmarad az ideálistól, egyéni és társadalmi
szempontból is kiemelten fontos, hogy a legkorszerűbb eljárásokhoz az érintett
betegek megfelelő helyen és módon hozzáférjenek. Orv Hetil. 2023; 164(51):

EFFECT OF PREPARATION ACETONE ON FISH BONES SYNTHESIZED THROUGH SINTERING METHOD TO IMPROVE HYDROXYAPATITE CHARACTERISTICS
Authors: Kusumawardani Ratna , Noviyanti Atiek Rostika , Nurhadi Mukhamad , Umar Akrajas Ali
Published: January 2024

In the development of advanced materials and various technological applications, the preparation and sintering processes have become two important factors in determining material characteristics. This research focuses on two main aspects, namely the effect of fish bone preparation by soaking in acetone and the surface area of the material in the sintering process as part of the process of developing better materials. This research aims to determine the effect of soaking fish bone powder with acetone and the effect of the surface area of sintered fish bones to produce hydroxyapatite (HA). The immersion process with acetone is included in the sample preparation stage, while the sintering process is included in the material synthesis stage. These two things can affect the characteristics of the HA produced after analysis from the X-ray diffraction test. The HA structure obtained from all samples is hexagonal with cell parameter values a = b ≠ c and space group P 63 / m, where all samples have a value range of a = b = 9,42 Å and c = 6,88 Å. HA crystallinity was identified through the XRD peak at 2θ = 25,8 (002); 31,7 (211); 32,1 (112); 32,8 (300); 34,0 (202); 39,7 (310); 46,6 (222); 49,4 (213); 50,4 (321). The PAF-900 and CAF-900 samples are similar to HA in JCPDS 01-089-4405 whose compound formula is Ca5(PO4)3(OH) while the PWAF-900 sample is similar to HA in JCPDS 01-075-3727 whose compound formula is Ca5(PO4)3(CO3)0.01(OH)1.3. The percentage of crystallinity of PAF-900, CAF-900, and PWAF-900 respectively was 84,767; 73,506; and 71,962% with HA grain sizes of 0,8964; 0,6808, and 0,7398 nm. The HA density of PAF-900 and CAF-900 samples is 3,149 g/cm3 while PWAF-900 is 3,146 g/cm3. Based on this description, it can be concluded that the soaking preparation stage with acetone produces HA with the chemical formula Ca5(PO4)3OH with a higher percentage of crystallization and is denser compared to HA obtained without going through the soaking preparation stage with acetone. The sintering stage also plays an important role in increasing the crystallization percentage. The surface area of the material being sintered also influences the percentage of crystallization and the grain size of the resulting HA. Sintered fish bone powder produces a greater percentage of crystallization and grain size than fish bone chunks

Authors: Fadhila Salma Iza , Hayati Elok Kamilah , Rafi Mohamad , Sabarudin Akhmad
Published: January 2024

Acalypha indica is an abundant and obtainable wild weed plant in Indonesia. This is a possible opportunity to enhance its utility. The effect of free radicals is one of the factors that contribute to oxidative stress in the body, which can lead to cell damage and trigger various diseases. Plants rich in antioxidants can inhibit free radical reactions and protect the body from oxidative stress. In this study, we conducted the identification of major metabolite compounds using UHPLC-Q-Orbitrap HRMS from 70% ethanol extracts of Acalypha indica. We also performed phytochemical and antioxidant activity tests with various concentrations of ethanol-water solvents including water, 30%, 50%, 70% ethanol, and absolute ethanol to determine the optimal extraction conditions and the influence of solvent concentration on the antioxidant activity of Acalypha indica extract. The results of UHPLC-Q-Orbitrap HRMS identification showed that the 70% ethanol extract of Acalypha indica contains 10 major compounds suspected to correlate with its antioxidant activity. These include five flavonoids compounds (palasitrin, vitexin 2"-o-p-coumarate, isorhamnetin 3- (3",6"-di-p-coumarylglucoside), peucenin, and sulfuretin), two amino acid compounds (2-amino-3-carboxymuconic acid semialdehyde and N-Acetyl-L-phenylalanine), two carboxylic acid compound (citric acid and traumatic acid), and one phenolic compound (quinic acid). Phytochemical tests show positive results for flavonoids, tannins, alkaloids, and triterpenoids in each of water, 30%, 50%, 70% ethanol, and absolute ethanol extracts. The best antioxidant activity was obtained from the 70% ethanol extract with an IC50 value of 47.064 ppm, categorizing it as an extremely strong antioxidant.

The scientific objective of this article is to gain a deeper understanding of crisis intervention as an immediate action in a difficult situation, corresponding to the needs of the present day. The article focuses on the issue of crisis intervention, which can play a stabilising role in a post-modern, dynamic reality. The article uses an analysis of scientific texts. The content of the article explains the development and specificity of crisis intervention and outlines the role it can play today. Crisis intervention is not a psychotherapeutic intervention, a long-term process. It is an immediate action aimed at quickly restoring the current functioning of persons and communities experiencing difficult situations. The crisis intervention does not solve the per problems for them, but accompanies them. The article indicates that crisis intervention is an action that responds to the need to create spaces where those experiencing difficult situations could benefit from the 24-hour support needed in an unstable reality.

Full-scale tests of a long energy pile subjected to separated and coupled thermo-mechanical loads
Authors: Zhang Guangzhe , Du Fenglei , Cheng Xiaohui , Li Xiangyu , Mao Anqi , Cao Benyi
Published: January 2024

In this paper, four individual full-scale tests were carried out to study the mechanical response of a cast-in-place energy pile beneath a liquefied natural gas (LNG) tank subjected to separated and coupled thermo-mechanical loads. The results show that the temperature profiles displayed a comparable trend in response to pile heating, cooling and recovery. Specifically, the temperature at the mid-depth of the pile fluctuated rapidly, while the changes at both ends were relatively slower. During the thermal stages, when the pile had the flexibility to expand or contract, the observed strain at the pile head significantly deviated from the free thermal strain. In contrast, the strain at the pile toe was relatively aligned with the free thermal strain. The thermally induced stress obtained at the end of the coupled loading–cooling stage was found to exceed the tensile strength of the C40 reinforced concrete. However, under the actual testing conditions, both the settlement and the bearing capacity of the pile remained well within the required values, ensuring the structure of the LNG tank will not be damaged.

Published: January 2024

O objetivo deste artigo foi analisar o desempenho dos estados do nordeste brasileiro no tratamento final dos Resíduos de Serviços de Saúde (RSS). Para tanto foi desenvolvida uma pesquisa exploratória e documental, na qual foram analisados os dados do Sistema Nacional de Informações sobre Saneamento (SNIS). A gestão dos resíduos sólidos tem sido alvo de debates ao longo dos tempos, a discussão reside no alto nível de degradação ambiental que esse material representa, tal a situação é reforçada quando se trata dos RSS. Pois, além do fator degradação, eles acumulam o potencial de contaminação e proliferação de doenças, caso não recebam o tratamento adequado, portanto conhecer m. A gestão adequada dos RSS produzirá cidades mais saudáveis. Os dados apontam que o uso de lixões está presente em todos os estados, mesmo sendo essa uma destinação imprópria. Contudo, alguns estados como a Bahia e o Ceará já lideram o processo de migração para destinações otimizadas, como os aterros sanitários e de unidades de descontaminação, essenciais ao tratamento dos RSS. Por fim, os resultados permitiram a construção de um ranking entre os estados nordestinos, figurando nos primeiros lugares os estados que apresentam maior capacidade de fornecer a destinação final adequada aos RSS, bem como evidenciou a imprecisão do SNIS em não segregar os RSS por categorias. A compilação dos dados permitiu esclarecer as especificidades dos RSS e possibilitará aos demais estados seguirem a trilha da evolução traçada.

Authors: Grzegorzewski Flávia Costa , Nemer Luciana , Silva Felipe Gustavo
Published: January 2024

O trabalho apresenta uma análise da aplicação dos conceitos de sustentabilidade junto à produção de arquitetura de discentes da Escola de Arquitetura e Urbanismo da Universidade Federal Fluminense. A pesquisa investiga os desdobramentos do conceito, elencando oito princípios e os demonstrando em exemplos práticos de projetos. O texto também aborda como se formaram as bases e os parâmetros através de dimensões e indicadores; não obstante, descreve a trajetória da sustentabilidade nas cidades, na construção e na arquitetura, complementada pelas Agendas Mundiais. Por outro lado, a construção civil, sendo um dos maiores consumidores de energia em todo mundo, necessita de instrumentos para otimização sustentável e as certificações de eficiência energética se mostram como um meio palpável na busca pela redução do impacto do setor de arquitetura, sejam as internacionais como o Building Research Establishment Environmental Assessment Method (BREEAM) e o Leadership in Energy and Environmental Design (LEED), como também as nacionais, como o Selo Procel Edifica.

There are critical challenges to measuring substance use exposure, particularly among adolescents, with major limitations to the most common methods of assessment – self-report and biomarker (urine, saliva) analysis. This study examines the use of wipe sampling as a measure of adolescent illicit substance exposure. Among low-income families, this study compared forensically analyzed wipe samples from 51 adolescents’ homes and cell phones with self-reported substance use to identify overlaps and discrepancies. There were major gaps between adolescents reporting any substance use in the past year and adolescents whose homes and/or cell phones tested positive for illicit substances via wipe sample analysis. This study builds upon previous adolescent substance use and exposure research, highlighting the profound limitations of self-reported use, and introducing wipe sampling as an effective measure of toxicant exposure. Wipe samples also provide a means to examine environmental contexts in new novel ways.

El trabajo que presentamos surge de un proyecto de innovación docente desarrollado en la Universidad de Extremadura. Tiene como propósito explorar nuevos itinerarios formativos en relación con la competencia digital, la autonomía y el trabajo colaborativo, en estudiantes de Grado de Maestro/a en Educación Primaria, Educación Infantil y Psicopedagogía a través del desarrollo de sus Entornos Personales de Aprendizaje. Estos nuevos entornos hacen posible el fomento de comunidades virtuales de aprendizaje, que combinan ámbitos formales e informales de aprendizaje. Para dicho estudio hemos analizado su tecnografía, valoraciones, opiniones y experiencias acerca de cómo aprende el alumnado. El estudio de las aportaciones del alumnado corrobora que este nuevo enfoque de aprendizaje favorece la adquisición de competencias personales tales como difundir información y comunicarse y ampliar otras competencias profesionales necesarias en el ámbito laboral.AbstractThe present paper stems from a large project of teaching innovation developed at the University of Extremadura. Its purpose is to explore new training routes in relation to the several skills such as teamwork, self-autonomy and digital competences. Specifically, we present the experience carried out with students from Elementary Education Degree, Early Childhood Education Degree and Learning Psychology Degree using and developing Personal Learning Environments. These new environments make possible the development of virtual learning communities that combine formal and informal learning environments. For this study, we have analyzed its technopraphy, ratings, opinions and experiences that the students expressed about the learning with this tool. The study of student contributions confirmed that this new learning approach favours the acquisition of personal skills such as communicate and disseminate information and expand other professional skills needed at labour market.

Authors: Hernández Rivero Víctor Manuel , Sosa Alonso Juan José
Published: January 2024

Este artículo recoge los resultados de un estudio cuya finalidad es conocer la percepción que el conjunto de asesorías especialistas en TIC de los Centros del Profesorado (CEP) de Canarias  tienen de las funciones que desempeñan, de las estrategias de apoyo al profesorado que despliegan, y de las demandas de asesoramiento que reciben en el marco del proceso de implantación de las tecnologías en las escuelas. También se identifican algunas problemáticas con que se encuentran en el desempeño de su labor. El diseño de investigación se apoya en metodología de tipo cualitativo empleando la entrevista como técnica de recogida de información. Se evidencia que el rol del asesor TIC está en proceso de redefinición, evolucionando desde un perfil de experto en cuestiones de tipo técnico e informático a otro más pedagógico centrado en aspectos didácticos relacionados con la incorporación de las tecnologías en las aulas y las escuelas.AbstractThis article presents the results of a study aimed at knowing the perception that the set of consulting specialists in ICT Teacher Centers (CEP) Canary (18 subjects) have the roles, strategies to support teachers deploying, and the demands of advice given in the context of the implementation of technology in schools. Some problems they encounter in the course of their work are also identified. The research design is based on qualitative methodology using the interview as data collection technique. It is evident that the role of the ICT advisor is being redefined, evolving from a profile expert on issues of technical and computer type to another more focused on didactic teaching aspects of the incorporation of technology in classrooms and schools.
La educación para la competencia digital en los centros escolares: la ciudadanía digital / Education for digital competence in schools: digital citizenship
Authors: Sanabria Mesa Ana Luisa , Cepeda Romero Olga
Published: January 2024

En este artículo se reflexiona sobre la respuesta de los centros educativos ante los «conceptos emergentes» que están surgiendo en torno a la omnipresencia y desarrollo exponencial de las tecnologías digitales en los contextos sociales. En una primera parte se presenta un análisis teórico de dichos conceptos emergentes a partir del propio concepto de competencia digital. Se propone un esquema orientativo para el estudio de la competencia digital para la educación de la ciudadanía digital en los centros escolares. La segunda parte pretende acercarse al concepto de competencia y ciudadanía digital que se maneja en la realidad educativa y qué dimensiones se contemplan en su integración en las aulas. Se presenta un estudio cualitativo al objeto de analizar el concepto de competencia digital reflejado en los PTIC de los centros públicos de Infantil y  Primaria para comprobar si existe relación, y en qué sentido, entre el concepto de ciudadanía y sabiduría digital y el nivel de integración del uso de las TIC en el aula. Los resultados permiten afirmar que sí hay relación y que la evolución del concepto de competencia digital tiene un claro reflejo en las dimensiones (siguiendo el esquema orientativo propuesto) contempladas en los objetivos, contenidos y aprendizajes que se plantean en los PTIC de los 11 centros objeto de estudio, ubicados en diferentes niveles de integración de las TIC en las aulas.AbstractThis article reflects on the response of schools to the 'emerging concepts' that are emerging around the omnipresence and exponential development of digi tal technologies in social contexts. In the first part theoretical analysis of these emerging concepts it is presented from the very concept of digital competence. a policy framework for the study of digital competence for digital citizenship education in schools is proposed. The second part tries to approach the concept of competition and digital citizenship that is handled in the educational reality and what dimensions are contemplated in their integration in the classroom. A qualitative study is contemplated in order to analyze the concept of reflected digital competition in PTIC of primary schools to check whether a relationship exists , and in what sense , between the concept of citizenship and digital wisdom and level of integration use of ICT in the classroom. The results confirm that there is a relationship and that the evolution of the concept of digital competence is clearly reflected in the dimensions (following the trend chart proposed) referred to in the objectives, content and learning that arise in the PTIC of the 11 centers object studio , located at different levels of integration of ICT in the classroom.
La metamorfosis digital del material didáctico tras el paréntesis Gutenberg / The digital metamorphosis of didactic material after the parenthesis Gutenberg
Authors: Area Moreira Manuel
Published: January 2024

This article is an essay that analyzes the changes or mutations that are taking place in the characteristics and functionalities of educational materials in the context of the digital society. It is based on the thesis that the hegemonic didactic material of the modern school (specifically textbooks) responded to the logic of printed culture characterized by packaging knowledge and a standardized and mass curriculum development model. In this S. XXI educational materials are affected by digital transformation whose mutation is described in terms of five dimensions or areas: artifactual or technological, pedagogical, teaching functionality, learning functionality, and production processes, distribution and consumption. It concludes by pointing out that the metamorphosis of the didactic material does not consist only in a change of the technological format, but it must be fundamentally of the cultural story and of the pedagogical functionality of the material.
Análisis del concepto de Competencia Digital Docente: una revisión sistemática de la literatura
Authors: Hidalgo Mario
Published: January 2024

The technological revolution experienced in today’s society has led educational organisations to assume the responsibility of training skills and abilities for this new context. Despite the high degree of complexity within technology-mediated ecosystems, the scientific literature seems to agree that the development of teachers' digital competence is identified to be a key variable of success. The definition of digital competence is however not clearly delineated. Moreover, direct and indirect interactions within this technology-mediated teaching and learning process are not clearly identified. The objective of this study is to define the concept of Digital Teaching Competence through a Systematic Literature Review published between 2017 and 2022, using the Scopus and Dialnet databases. A total of 316 references in English and Spanish were identified, of which 32 were selected for the final analysis, following the PRISMA protocol guidelines. The results confirm the existence of a high degree of conceptual fragmentation, as well as the lack of agreement on the terminology to be used. There is a need to reach a consensus on a taxonomy that facilitates, on one hand, the analysis of the elements that make up Digital Teaching Competence, and on the other hand, the improvement of the capacity to analyse specific contextual variables that contribute to enhancing technology-mediated teaching and learning processes.
Percepciones de maestros en prácticas sobre aceptación de tecnologías móviles en procesos de enseñanza-aprendizaje. Un estudio de caso
Authors: Caballero-Mariscal David
Published: January 2024

The pandemic crisis highlighted the need for a technological and digital transformation of the university, a process that has already begun and that has marked a before and after in the incorporation of technologies in the teaching-learning processes. On the other hand, teachers in training are a privileged group as they are at the end of their training process, in contact with active teachers and will be pillars of social training. For this reason, this study aims to analyze the perceptions of trainee teachers at the University of Granada on the acceptance and inclusion of smartphones in teaching and learning processes, as a result of the Covid-19 pandemic crisis. A qualitative methodology (focus group) was implemented with a sample of 16 trainee teachers belonging to the area of social sciences. The results showed an incorporation of technologies in future teachers, the need for the implementation of smartphones, as well as mobile literacy for students and teachers. In the same way, generational differences, the relevance of motivation and perception in usefulness and ease of use of devices are highlighted. It is concluded that there is a need for training actions in teachers and educational centers to provide an effective response to social and educational needs. For this reason, universities, educational institutions and teachers must strive to understand the scope of mobile teaching and the possibilities of smartphones in increasing motivation and the acquisition of basic skills. Future studies are needed to broaden the scope of analysis to different areas and contexts
Onomastické termíny obyvateľské meno, katojkonymum a demonymum
Authors: Valentová Iveta
Published: January 2024

The article deals with the characteristics of the onomastic terms inhabitant name, katoikonym, and demonym and with their place (position) in the system of onomastic terminology. The author analyses the definition, content and character of these terms and their use, primarily in Slovak linguistics and onomastics. Different views on their content also lead to an orthographic problem. This problem concerns in particular the differentiated writing of initial letters in the names of the objects that are denoted by them. The problem of writing capital or small initial letters comes to the fore in Slovak, especially in the case of so-called living (unofficial) inhabitant names or inhabitant nicknames.
„Życzeniem jego jest nadać mu imię Wincenty Kadłubek”. Kult bł. Wincentego w świetle małopolskich ksiąg metrykalnych (poł. XVIII–początek XX w.)
Authors: Rutkowski Rafał
Published: January 2024

W oparciu o małopolskie księgi metrykalne z okresu 1765–pocz. XX w. zebrano materiał antroponimiczny, pokazujący, że imię Wincenty Kadłubek było nadawane wówczas na chrzcie. Jest to niewątpliwie związane z kultem beatyfikowanego podówczas biskupa krakowskiego, trudno to natomiast powiązać z recepcją jego Kroniki. Zwyczaj ten praktykowany był raczej wśród warstwy chłopskiej i mieszczańskiej, a jego charakterystyczną cechą jest to, że imię Kadłubek nadawano chłopcom urodzonym wczesną jesienią, tzn. w okolicach wspomnienia liturgicznego bł. Wincentego.
