An instrument for measuring performance in geometry based on the Van Hiele model
[EN] In this paper we present the process of constructing a test for assessing student performance in geometry corresponding to the first year of Secondary Education. The main goal was to detect student errors in the understanding of geometry in order to develop a proposal according to the Van Hiele teaching model, explained in this paper. Our research methodology took into account reliability using Cronbach's alpha coefficient, as well as the construct validity, with the extraction of 13 factors that accounted for a high percentage of variance. This result leads us to conclude that the instrument constructed has the appropriate technical and pedagogical features to be considered an original and significant contribution to the field of geometry teaching. The final version of the test constructed after the extraction of factors is shown in the Appendi
Communicating Heritage Through Contemporary Art Based on Technologies: a Proposal for the Heritage Sites in the WARMEST project
WARMEST MSC-RISE-H2020 project has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie, grant agreement #777981An integrative and innovative communication model to enhance the knowledge, comprehension and delectation of cultural and natural heritage through technology-based contemporary art is described. By relating these two traditionally dissociated fields (heritage and contemporary art), a particular form of dialogue between them occurs and it is transferred to society within an emotional and intellectual discourse away from those merely informative. The heritage sites Alhambra Lions Court in Granada (Spain), Santa Croce's second cloister in Florence (Italy) and Marzamemi underwater Wreck of Church (Italy) are under study in the framework of the European research and knowledge transfer project, WARMEST3. A strategy of communication based on pieces and actions of contemporary art will be proposed to set up a new frame in the diffusion of the cultural and natural legacy. That will encourage its preservation and, at the same time, will set up a new research line around site specific art work related to heritage sites communication.European Commission

La integración de los inmigrantes en la comunidad educativa: objetivo número 15 del pacto mundial por una migración seguro, ordenada y regular
[ES] Desde LOMLOE se potencia la educación inclusiva y equitativa de calidad. En este trabajo analizaremos si se está avanzando en España en la mejora de la inclusión social y la integración educativa de los migrantes, como indica el Objetivo número 15 del Pacto Mundial por una Migración Segura, Ordenada y Regular. Se han analizado las respuestas de 378 participantes sobre la valoración del derecho a la educación, valoración del impacto la incorporación de inmigrantes en los centros educativos, valoración de la percepción de xenofobia y valoración económica. La mayoría de las personas creen que los inmigrantes tienen derecho a la educación y que su inclusión en las aulas es enriquecedora, aunque se considera que los niveles educativos han bajado debido a los emigrantes y deberían tener un mayor presupuesto económico las escuelas que tienen mayor número de inmigrantes. [EN] LOMLOE promotes inclusive and equitable quality education. In this paper we will analyze whether progress is being made in Spain in improving social inclusion and education integration of migrants, as indicated in Goal 15 of the Global Compact for Safe, Orderly and Regular Migration. The responses of 378 participants were analyzed on the evaluation of the right to education, evaluation of the impact of the incorporation of immigrants in educational centers, evaluation of the perception of xenophobia and economic evaluation. The most people believe that immigrants have the right to education and that their inclusion in the classroom is enriching, although it is considered that educational levels have dropped due to immigrants and that schools with a higher number of immigrants should have a larger economic budget
Evolutionary processes in the development of errors in subtraction algorithms
[EN] The study of errors made in subtraction is a research subject approached from different theoretical premises that affect different components of the algorithmic process as triggers of their generation. In the following research an attempt has been made to investigate the typology and nature of errors which occur in subtractions and their evolution throughout primary education. The main aim of the research is to examine whether in our school context systematic errors are made and if these decrease throughout schooling. In order to do this, we carried out a rigorous analysis of over 7140 subtractions done by children of 7 to 13 years of age in 2nd, 3rd, 4th, 5th and 6th years of primary school, using a sample of 357 primary school students who were tested with the VanLehn 20 subtractions test. The SPSS 11.5 computer programme was used to analyze the data generated by the tests. One hundred and twenty-two different errors were analyzed, the results showing systematic errors in 55% of the cases. We likewise found that the evolution of the error throughout primary education shows certain similarities with the results obtained in other teaching contexts. The results obtained are undoubtedly valuable for programming the teaching process
Erreurs algorithmiques. Processus cognitifs et actions éducatives
In this paper we define the cognitive space of subtraction and place emphasis on procedural control and on the processes that need to be improved by the educa- tional framework for proper acquisition. We describe the theory behind error acquisi- tion. To do this, we consider the analysis of negative transfer processes induced from the educational context. The analysis is inscribed within the intersection between educational theory and cognitive theories of algorithmic learning.En este trabajo definimos el espacio cognitivo de la sustracción e incidimos en el control del procedimiento y en los procesos que tiene que potenciar el marco educativo para su correcta adquisición. Describimos la teoría que subyace a la adquisición del error. Para ello, tomamos como referencia el análisis de los procesos de transferencia negativa inducidos desde el contexto educativo. El análisis se inscribe en la intersección entre la teoría de la educación y las teorías cognitivas sobre el aprendizaje algorítmico.Dans cet article, on définie l’espace cognitif de la soustraction en mettant l’accent sur le contrôle des mécanismes pour son correcte acquisition et sur les diffé- rents processus devant être mis en place par le cadre éducatif. La théorie sous-jacente à l’acquisition de l’erreur y est décrite. Pour ce faire, on tient compte de l’analyse des processus de transfert négatif induits par le contexte éducatif. L’analyse s’inscrit au point de rencontre de la théorie de l’éducation et des théories cognitives sur l’apprentissage algorithmique
Academic Performance and ICT. A Study with Educational Websites at the University of Murcia, Spain
Se analizan las relaciones entre implicación del alumno en la utilización de webs didácticas de asignatura (a través del número de accesos) y rendimiento académico (calificaciones). Todo ello en 189 alumnos de 3 asignaturas de la Universidad de Murcia. Se comprueba como esa implicación de los estudiantes con la utilización de la web didáctica de su asignatura se relaciona positivamente con sus resultados académicos (analizando los datos tanto con técnicas correlaciónales como con técnica de ANOVA). El resultado supone un paso más allá de la constatación previa existente de la buena acogida que los alumnos hacen de estas herramientas didácticas.Connections between the student's involvement in the usage of teaching webs (via access count) and academic performance (grades) are analyzed in 189 students of 3 subjects at the University of Murcia. It can be observed that involvement of students with the use of teaching webs is positively related to their academic performance (data was analyzed using both correlational and ANOVE techniques). This result is a step beyond the previous acknowledgement of the favorable reception of those didactical tools by the students.Universidad de Murci
Please, Don’t Shoot the Meta-analysis: A Response to “A Commentary to Toddler Screening for Autism Spectrum Disorder: A Meta-analysis of Diagnostic Accuracy by Sánchez-Garcia et al. 2019”
[EN] In their letter to the editor, Øien et al. (2019) highlight concerns about conducting a meta-analysis on screening instruments for ASD. They focus on lack of information and heterogeneity among the individual studies pooled in the research by Sánchez-García et al. (2019). The authors do not question the experimental method; even stating that it “provides us with important knowledge of how screening instruments perform across various studies.” Of course, clinical and methodological heterogeneity could cause statistical heterogeneity leading to inaccurate conclusions in a meta-analysis (Higgins and Altman 2008). Although this should not preclude conducting meta-analytic investigation, since understanding the causes of heterogeneity increases its scientific value and the clinical significance of the results (Thompson 1994). Therefore, it is not a threat or concern to synthesize the available evidence (Lijmer et al. 2002). Having said that, the methodological limitations among studies included in a meta-analysis is not specific to ASD screening; yet, there is a large literature about the viability and importance of diagnostic or screening accuracy meta-analyses. Given empirical support in other disorders, it is logical to apply them to a meta-analysis in screening instruments for ASD. There are three specific points that warrant further consideration
Bioethical perspective of the limitation of therapeutic effort in adult terminal patients. Systematic review
Introducción: Ante la capacidad de mantenimiento de las funciones vitales de forma artificial, surgen nuevas preocupaciones éticas en los profesionales sanitarios en relación con la muerte. Se cuestiona desde la ética si el equipo asistencial debe hacer siempre todo lo necesario y posible para impedir la muerte de un paciente.Objetivo: Analizar los aspectos bioéticos de la limitación del esfuerzo terapéutico en pacientes en el final de la vida, fomentar la reflexión y contribuir a mejorar los cuidados en el final de la vida.Método: Se realizó una revisión narrativa e integradora de la literatura científica mediante la búsqueda de publicaciones en metabuscadores y bases de datos de PubMed, SciELO y la revista de Nursing Ethics. Se identificaron 6.325 estudios publicados a partir de 2018 y se incluyeron un total de 9 artículos. Resultados/Discusión: Se describen las dificultades que presentan los profesionales en relación a la toma de decisiones en el final de la vida, la necesidad de mejorar la formación en ética y en aspectos relacionados con pacientes que se encuentran en sus últimos días, los cuidados paliativos y la limitación del esfuerzo terapéutico. Solo una minoría de los estudios están enfocados en enfermería.Conclusiones: Las decisiones del profesional están influenciadas por valores, emociones, creencias y experiencias, que unidas a la dificultad que existe en ocasiones para establecer un diagnóstico clínico certero, dificulta las decisiones de limitación de esfuerzo terapéutico. Se hace necesario mejorar la formación en ética y conocimiento de los procesos de final de la vida por parte de los profesionalesIntroduction: Faced with the ability to maintenance vital functions artificially, new ethical concerns arise among health professionals regarding death. It is been questioned from ethics if the care team should always do everything necessary and possible to prevent the death of a patient. Objective: to analyze the bioethical aspects of limiting therapeutic effort in end-of-life patients, encourage reflection and contribute to improving end-of-life care. Method: a narrative and integrative review of the scientific literature was performed by searching for publications in meta-search engines and databases of PubMed, SciELO and the journal of Nursing Ethics. A total of 6,325 studies published since 2018 were identified and a total of 9 articles were included. Results/Discussion: Issues presented by professionals regarding making-decisions at the end of life, the need to improve training in ethics and aspects related to patients in their last days, palliative care and the limitation of therapeutic effort are described. Only a minority of studies are focused on nursing. Conclusions: professional's decisions are influenced by values, emotions, beliefs and experiences, which, together with the difficulty that sometimes exists to establish an accurate clinical diagnosis, makes it difficult to limit therapeutic effort. It is therefore necessary to improve training in ethics and knowledge about end-of-life processes from professionals
Wastewater Treatment by Advanced Oxidation Process and Their Worldwide Research Trends
Background: Water is a scarce resource and is considered a fundamental pillar of sustainable development. The modern development of society requires more and more drinking water. For this cleaner wastewater, treatments are key factors. Among those that exist, advanced oxidation processes are being researched as one of the sustainable solutions. The main objective of this manuscript is to show the scientific advances in this field. Methods: In this paper, a systematic analysis of all the existing scientific works was carried out to verify the evolution of this line of research. Results: It was observed that the three main countries researching this field are China, Spain, and the USA. Regarding the scientific collaboration between countries, three clusters were detected—one of Spain, one of China and the USA, and one of Italy and France. The publications are grouped around three types of water: industrial, urban, and drinking. Regarding the research, 15 clusters identified from the keywords analyzed the advanced oxidation process (alone or combined with biological oxidation) with the type of wastewater and the target pollutant, removal of which is intended. Finally, the most important scientific communities or clusters detected in terms of the number of published articles were those related to the elimination of pollutants of biological origin, such as bacteria, and of industrial nature, such as pesticides or pharmaceutical products
