Autoevaluación del estudiante : ¿qué hemos aprendido y cuáles son los desafíos?
2015
Este artículo examina los principales temas que han sido una preocupación constante para los investigadores en el tema de la auto-evaluación de los alumnos en el mundo de habla inglesa. Estos incluyen si los estudiantes deben calificar su propio trabajo y si lo hacen adecuadamente, si hay bastantes precisión en la calificación y si la autoevaluación les empodera. Presentamos estos temas dentro de su contexto histórico, el análisis incluye los contextos y las creencias que motivaron su desarrollo. Los datos demuestran que la poca aceptación de autoevaluación está en contra de la investigación sobre la teoría y la práctica, la cual pone de relieve su importancia para apoyar el aprendizaje de…
External Inspection or School Self‐evaluation? A Comparative Analysis of Policy and Practice in Primary Schools in England and Finland
1998
The findings reported in this article form part of a wider comparative research project investigating the processes of curriculum change in primary schools in England and Finland during the period 1994-97. The two countries' policies on inspection and monitoring were moving in opposite directions. Finland has abandoned its national inspection system and is promoting school self-evaluation, whilst in England external accountability has been imposed on schools through Office for Standards in Education (OFSTED) inspections. Using data from case studies of six schools in each country, it is argued that each country has something to learn from the practice of the other. In England, the impact of…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2021
Resumen basado en el de la publicación Este trabajo está fundado en una concepción constructivista del aprendizaje de las ciencias, más concretamente en el modelo conocido como enseñanza aprendizaje como investigación orientada. De acuerdo con esta base teórica, los autores han desarrollado una investigación empírica enmarcada dentro de la enseñanza de la electroestática en educación secundaria. Los modelos desarrollados permiten valorar el aprendizaje logrado por los estudiantes. De acuerdo con los resultdos podría decirse que los materiales desarrollados y la forma en que se ha trabajado con ellos han contribuido a un aprendizaje más significativo y ha favorecido una actitud más positiva …
A strategy to improve the comprehension and learning in morphological science: Powerpoint presentation
2003
In this paper, a hypertext to the Morphological Sciences in biological area was developed and evaluated. The application with format of digital atlas approaches Anatomical, Histological and Functional concepts about the man and animals in integrated form. PowerPoint presentation was developed to operators which experience in the handling of software are limited. This digital resource was qualified as a good complement of other didactic materials. In this knowledge area offers opportunity to develop significant knowledge to improve the understanding and learning through an interactive methodology.
How Enlightenment is taught in Higher Education? An analysis of textbooks, their contents and gender
2017
Con el presente artículo tratamos de analizar cómo se enseña y cómo se ha enseñado el movimiento ilustrado en las aulas de secundaria de nuestro país, a través del estudio de algunos materiales curriculares de 2.º de Bachillerato correspondientes a la asignatura de Historia de España. Estos han sido elaborados en distintos momentos, los últimos años del periodo de vigencia de la Ley de Ordenación General del Sistema Educativo (1990) y en el marco de la actual Ley Orgánica para la Mejora de la Calidad Educativa (2013). Nuestro objetivo es tratar averiguar si las innovaciones aportadas por la historiografía más reciente sobre la Ilustración se han trasladado o no a los mismos. También si esto…
Improving geoconservation of the palaeontological heritage through a semiotic vision
2019
The panoply of reasons that may attract people to fossils, which result from the meaning they attribute to these palaeontological objects, may contribute to endangering of the integrity of the fossil record. Semiotics can be of great help to assist geoconservation actions, usually based only on expertise statements, and are of particular relevance in palaeontological heritage inventory, evaluation, conservation, valuation and monitoring procedures. This work argues that fossils can be envisaged as signs displaying different meanings among experts and non-specialists. Such meanings support the heritage contents and values attributable to any palaeontological object and are affected by the re…

Apoptosis and cell growth arrest in A375 human melanoma cells by diorganotin(IV) and triorganotin(IV) complexes of [meso-Tetra(4-sulfonatophenyl)porp…
2011
In previous studies we have demonstrated that two derivatives of meso-Tetra(4-sulfonatophenyl)porphine (TPPS), (Bu2Sn)2TPPS and (Bu3Sn)4TPPS, cause apoptotic death of A375 melanoma cells and, at lower concentrations, arrest of cell proliferation. In the present study, we examined if the manganese metal inside the porphyrin cavity could improve the efficacy of this class of compounds. Thus, [meso- Tetra(4-sulfonatophenyl)porphine]Mn(III)Cl (=MnTPPS) derivatives, namely (Me2Sn)2MnTPPS, (Bu2Sn)2MnTPPS, (Me3Sn)4MnTPPS and (Bu3Sn)4MnTPPS, were tested on the A375 human melanoma cell line. A cytotoxicity assay showed that (Bu2Sn)2MnTPPS and (Bu3Sn)4MnTPPS were highly cytotoxic by inducing apoptosi…
INDICATORI PER LA VALUTAZIONE DELL'APPROPRIATEZZA DEL PERCORSO NASCITA
2015
Introduzione:La gravidanza, il parto ed il puerperio sono eventi fisiologici che possono talvolta complicarsi in modo non prevedibile e con conseguenze gravi per la donna, per il nascituro e per il neonato. Gli standard nazionali prevedono la razionalizzazione/riduzione progressiva dei punti nascita con numero di parti inferiore a 1000/anno, e l'abbinamento per pari complessità di attività delle UU.OO. ostetrico-ginecologiche con quelle neonatologiche/pediatriche, riconducendo a due i precedenti tre livelli assistenziali. I punti nascita privi di una copertura di guardia medico-ostetrica, anestesiologica e medico pediatrica attiva h 24, o di risorse umane e di attrezzature adeguate non dovr…
