During the archaeological interventions carried out there, a well-preserved burned surface was discovered. The burned sediments of this surface offered the opportunity to conduct full-vector archaeomagnetic dating to elucidate the age of the studied site. For determination of an archaeomagnetic intensity, two different methods (Thellier-Coe and Tsunakawa-Shaw) were applied to test their suitability and compare their reproducibility. Raman spectroscopy and rock magnetism revealed that the main magnetization carrier is magnetite, with varying concentrations of hematite and goethite. A good correlation is observed between high Qn ratio values (typically > 6) and strongly magnetic as well as stable orthogonal demagnetization diagrams of the natural remanent magnetization. The full-vector was recovered with a mean direction of Declination = 17.7°, Inclination = 54.0°, α95 = 3.2°, k = 309.2 and a mean intensity of 38.1 ± 9.0 µT. Comparison to the SCHA.DIF.4 k geomagnetic field model yielded a single dating interval of 995–1125 CE at 95 % confidence level. This result accurately dates one of the phases of abandonment of the site and coincides with some historically documented Muslim razzias, demonstrating the usefulness of the archaeomagnetic technique to reconstruct the occupational history of archaeological sites with burned remains.

Design/methodology/approach: Following the pedagogical framework of Experiential Learning Theory, a training program was designed for the subject of Environmental Education (EE) of the Primary Teacher Degree, incorporating CS activities. A quasi-experimental research was carried out with 36 primary preservice teachers who participated in this study, with a qualitative approach and without a control group. Two ad hoc surveys were defined for this study, the first one is related to prior knowledge about the term CS and a questionnaire was conducted to assess the educational potential of the CS after the implementation of the training program. The results showed a great initial lack of knowledge about CS but the appreciation of the preservice teachers after the educational intervention reveals the advantages and educational potential of CS. Findings: Preservice teachers consider that CS can and should be incorporated, as part of the course syllabus, into the teaching system and this can be done in scientific-technological subjects or in all subjects with an interdisciplinary and transversal approach, with the majority of responses indicating that the development of generic skills would be the greatest perceived benefit for students. Originality/value: There has been an increase in CS initiatives and projects in recent decades. However, despite the advantages for the participants and actors involved, its incorporation into higher education curricula is scarce.

Therefore, the starting point of this work is based on the absence of previous research that evaluates the role played by toy libraries in children's learning.Methodology:Through the application of the Delphi technique, the aim is to design and validate a guide of indicators focused on assessing and promoting family participation in toy libraries as a quality reference, to promote a process of continuous improvement. Results:This guide is structured in 6 areas, articulated in 22 standards and 55 quality indicators.Discussions:The main limitation has been the absence of established quality processes, as well as instruments that could facilitate the configuration of initiatives and programs that would value the involvement of families in toy libraries.Conclusions:This work contemplates the need to facilitate thatinvolvement and thus optimize the actions aimed at their correct integration into the environment, contributing decisively to child development and education for citizenship; La gestión de la calidad en las ludotecas es un escenario poco explorado, frente a otro tipo de servicios socio-comunitarios que han sido objeto de análisis recientemente, traduciéndose así en mejoras en su organización y en los servicios ofrecidos. Por tanto, el punto de partida de este trabajo se basa en la ausencia de investigaciones previas que evalúen el papel que desempeñan las ludotecas en el aprendizaje infantil. Metodología: A través de la aplicación de la técnica Delphi se ha diseñado y validado una guía de indicadores enfocados a valorar y promover la participación familiar en las ludotecas como referente de calidad, para favorecer un proceso de mejora continua. Resultados: Esta guía se estructura en 6 áreas, articuladas en 22 estándares y 55 indicadores de calidad. Discusión: La principal limitación ha sido la ausencia de procesos de calidad establecidos, así como de instrumentos que faciliten la configuración de iniciativas y programas que valoren la implicación de las familias en las ludotecas. Conclusiones: En este trabajo se contempla la necesidad de facilitar esa implicación y optimizar así las actuaciones encaminadas a su correcta integración en el entorno contribuyendo decisivamente al desarrollo infantil y a la educación para la ciudadanía.

EnvironmentalAttitudes Inventory (EAI) was used to measure the changein environmental attitudes (EA) of 173 preservice teachersthrough a pre-test–post-test experimental design withouta control group. Participation in the training program sig-nificantly improved EA in the 12 dimensions defined in theEAI. Of the dimensions included in the second order factorPreservation, Enjoyment of nature reached the largest effectsize and Environmental movement activism is the one thatobtains the smallest effect size. With regard to Utilization,all dimensions presented a large effect size. No significantdifferences were found in EA based on the gender variable.It can be concluded that the incorporation of citizen sci-ence activities in the EE program significantly improves EA.
