Impact of a Social Constructivist Instructional Strategy on Performance in Algebra with a Focus on Secondary School Students
2020
There have been perennial concerns on the low academic performance of students among researchers and other education stakeholders. Innovative teaching strategies have, therefore, gained prominence in the field of mathematics education. The purpose of this study is to investigate the impact of a social constructivist instructional strategy on students’ performance in algebra. The present study is quasi-experimental, and its type is a posttest control group involving 154 secondary school students that are randomly selected across four intact classes. The random selection of students to treatment and control controls is assumed to improve the validity of the results. Two research questions are…
La productividad científica sobre MOOC: aproximación bibliométrica 2012-2016 a través de SCOPUS
2017
Los Massive Online Open Courses (MOOC) han supuesto un hito en la educacion online en los ultimos cinco anos. La proliferacion de cursos y plataformas para su difusion han hecho que el fenomeno no solo sea un punto de reflexion educativa, social y politica, sino que tambien pase a la esfera academica como objeto de investigacion. El presente estudio analiza la productividad cientifica del fenomeno MOOC a partir del analisis de 752 publicaciones indexadas en la base de datos SCOPUS en el periodo 2012-2016. Los datos extraidos permiten realizar una radiografia global del estado del fenomeno, la evolucion que ha sufrido en los ultimos anos, el tipo de publicaciones que sustentan el fenomeno, l…
Prospective mathematics teachers’ self-referential metaphors as indicators of the emerging professional identity
2019
Ideals play a key role in a student teachers’ identity work. They form targets to strive for and a mirror for reflection. In this paper, we examine Finnish mathematics student teachers’ metaphors for the teacher’s role (N= 188). We classified the metaphors according to a model that identified teachers as subject matter experts, didactical experts, and pedagogical experts, with the addition of another two categories, self-referential and contextual. For the exploration of emerging professional identities, we studied the self-referential metaphors, which formed the most common category in the data. We observed that every third metaphor described either student teachers’ personalities or their…
Asymptotic Lipschitz regularity for tug-of-war games with varying probabilities
2018
We prove an asymptotic Lipschitz estimate for value functions of tug-of-war games with varying probabilities defined in $\Omega\subset \mathbb R^n$. The method of the proof is based on a game-theoretic idea to estimate the value of a related game defined in $\Omega\times \Omega$ via couplings.
¿Revuelta de Masaniello o revolución de Nápoles? Una reinterpretación
2020
Between 7 and 16 July 1647 a popular revolt, led by a young fishmonger, Masaniello, shook the city of Naples. The killing of Masaniello, however, did not lead to the end of the riots. On the contrary, the revolt involved the entire kingdom of Naples, radicalized in an anti-Spanish sense and resulted in the proclamation of the Republic and the call of a French prince, the Duke of Guisa. On these events, and especially on the fracture that permanently opposed people and nobles, historiography has long debated. It is possible, however, today, also on the basis of new archival documents, to propose a different interpretation of the events, which integrates the two moments and allows an updated …
Effects of Grazing on the Behaviour, Oxidative and Immune Status, and Production of Organic Dairy Cows
2019
This study compared the effects of a short daily grazing time with those of permanent free-stall housing on the behaviour, oxidative status, immune response, and milk production of organically reared cows. During a 63-day period, two homogeneous groups of eight lactating Brown cows were allocated to either housing (H) in a free-stall building for 24 h/day. Feeding was based on a total mixed ration or grazing (G) on barley grass for 5 h/day, and housing in a free-stall structure with feeding was based on the same total mixed ration offered to the H group. With regard to behaviour, H cows spent more time idling, walking, drinking, and self-grooming, whereas G cows showed a greater intent to e…
Revista complutense de educación
2020
Este artículo se encuentra disponible en la siguiente URL: https://revistas.ucm.es/index.php/RCED/article/view/63205/4564456553652 Introducción. Las normas legales se fundamentan en unos principios y valores que las instituciones escolares asumen y expresan en las diferentes dimensiones de su planificación y, sobre todo, en su acción. En aras de hallar los valores comunes que se supone impregnan los hechos educativos de cualquier escuela española, nos hemos decantado por realizar un estudio axiológico del currículo básico, que es el texto legal que orienta los desarrollos curriculares autonómicos y, en última instancia, de cada centro y equipo docente. Presentamos un estudio axiológico del …
Multimessenger Binary Mergers Containing Neutron Stars: Gravitational Waves, Jets, and γ-Ray Bursts
2021
Neutron stars (NSs) are extraordinary not only because they are the densest form of matter in the visible Universe but also because they can generate magnetic fields ten orders of magnitude larger than those currently constructed on earth. The combination of extreme gravity with the enormous electromagnetic (EM) fields gives rise to spectacular phenomena like those observed on August 2017 with the merger of a binary neutron star system, an event that generated a gravitational wave (GW) signal, a short γ-ray burst (sGRB), and a kilonova. This event serves as the highlight so far of the era of multimessenger astronomy. In this review, we present the current state of our theoretical understand…
THE RELATIONSHIP BETWEEN FOREIGN LANGUAGE ENJOYMENT AND GENDER AMONG SECONDARY GRAMMAR SCHOOL STUDENTS
2018
In the context of second language acquisition, foreign language enjoyment (FLE) is a relatively new concept. For that reason, none of the few research carried out in the field thus far has been focused on whether gender might be an important determinant of either a high or a low level of FLE. Thus, the purpose of the present paper was to examine the influence of FLE on learning English as a foreign language, as well as to investigate this relationship from the perspective of gender. The results of this study revealed that there are no statistically significant differences between males and females in FLE, while such differences are found in terms of the sources of FLE each gender perceives …
New national and regional Annex I Habitat records: from #60 to #82
2023
New Italian data on the distribution of the Annex I Habitats are reported in this contribution. Specifically, 8 new occurrences in Natura 2000 sites are presented and 49 new cells are added in the EEA 10 km × 10 km reference grid. The new data refer to the Italian administrative regions of Campania, Calabria, Marche, Piedmont, Sardinia, Sicily, Tuscany and Umbria. Relevés and figures are provided as Supplementary material respectively 1 and 2.
