“…Additionally, saltworks can be easily recreated on a smaller scale through different experiments and situations. Starting from this contextualized situation, it is possible to conduct activities where students have a more active role and help them build new models that allow them to describe, explain, predict, or propose hypotheses and interpret experimental results [71]. Specifically, focusing on halite, cubic, transparent, or translucent crystals can be easily created from artificially created salt brines through experiences in which different hypotheses and variables are tested, allowing a more active and constructivist learning to be achieved.…”

Salt harvesting through natural solar evaporation of salt brines is a practice notably abundant in the Iberian Peninsula. Such activity has been relevant for human consumption, food preservation, livestock feed, and various industries throughout history. The objective of this research is to analyze the productive history and conservation state of the salt evaporation ponds located in Naval and Peralta de la Sal (Huesca, Spain), as well as their didactic potential. These saltworks are associated with clay and gypsum levels from the Upper Triassic (Keuper). The earliest written records of salt production in the area date back to the 10th century, but they were exploited as early as the Bronze Age. Remains of most of the ponds and some buildings are still preserved and are easily accessed, which makes them very interesting from an educational perspective. Both on-site and off-site activities can be carried out to analyze their historical and current significance through modeling and argumentation practices. This can lead to a better understanding of how geology relates to everyday life and facilitate the development of positive attitudes among students towards geoheritage while raising awareness about its preservation and preventing its degradation.

En el artículo se describe una experiencia de aprendizaje llevada a cabo en la Universidad Nacional de Educación (UNAE) consistente en aplicar la secuencia didáctica de escritura en el marco de la asignatura Lectura y Escritura de Textos Académicos I con un doble propósito: por un lado, procurar la mejora progresiva de las competencias básicas del alumnado en el campo de la comunicación escrita; y, por otro, intentar fomentar la cohesión grupal gracias al análisis de unos autorretratos anónimos que sirvieron como pretexto para ejecutar los correspondientes ejercicios de redacción. El trabajo se desarrolla desde los parámetros de la investigación-acción y tiene un enfoque narrativo-interpretativo. Los resultados obtenidos ponen de manifiesto la importancia de atender las relaciones personales en cualquier contexto educativo —incluido el universitario—y plantea la necesidad de proponer actividades académicas dirigidas no solo a la adquisición de conocimientos teóricos, sino también a la formación integral y humana.

Rasch analysis and validity of the construct understanding of the nature of models in Spanish-speaking students

A questionnaire was recently developed for the use with the Spanish-speaking, and evidence have been provided about the construct internal validity by means of structural equation modelling. In this paper, two research questions were considered: (i) What new evidence does application of the Rasch model provide regarding the validity of this construct? (ii) What cutoffs should be applied to the constructed scales in order to differentiate between acceptable and insufficient levels of the construct being measured? Participants were 1,272 Spanish at both high-school and college level. The instrument is a pencil and paper questionnaire written in Spanish, comprising 20 items (5-point Likert-type scale) distributed evenly across four scales: beyond exact replicas, purpose of models, multiple models, and changing models. Students’ responses were coded on an ordinal scale from zero to four. We then conducted a Rasch analysis using both a multidimensional approach and a consecutive unidimensional approach for each dimension. Data provided new evidence regarding the internal validity of the four scales of the questionnaire. The Rasch analysis also allowed us to establish cutoffs for the constructed scales. The evidence provided by this, and the previous study suggest that the questionnaire may be useful as a diagnostic tool when applied to groups or populations of students. In addition, the identified cutoffs could, hypothetically, serve to differentiate between students with an adequate versus an insufficient understanding of the nature of models.
