Describir y dibujar en ciencias. La importancia del dibujo en las representaciones mentales del alumnado
2015
El presente trabajo pretende valorar los resultados obtenidos mediante la utilización del dibujo y de las descripciones a lo largo de una actividad basada en la observación de la morfología de las hormigas. Se plantea un trabajo individual y autónomo donde los participantes, en 3 etapas diferentes, deben tratar de dibujar o describir su observación de muestras vivas de hormigas. Los resultados de la investigación son muy significativos, puesto que encontramos diferencias estadísticas entre la utilización de las dos estrategias, así como entre las producciones de cada etapa, pudiendo ver cómo evolucionan sus representaciones mentales. Evidenciamos, de esta manera, que la estrategia de dibuja…
Evidence of neonatal memory of odor configuration
2013
The perception of some mixtures of odorants engages configural abilities, i.e. the perception of these mixtures as single odor objects. For instance, data in human adults demonstrated that a mixture of two odorants (AB), one smelling like strawberry and the other like caramel, generates the configural perception of the odor of pineapple (Le Berre et al., 2008; Barkat et al., 2012). Configural processing may be adaptive also for young organisms, to which rapid extraction of chemical information from the maternal environment, highly complex, is a prerequisite to survival. Thus, results in newborn rabbits suggest the perception of a unique odor in the AB mixture (smelling like configural pinea…
The odour of human milk: Its chemical variability and detection by newborns
2019
International audience; Human milk odour has for long elicited research interest with regard to its function in breastfeeding initiation. The present review aims to provide an overview of the behavioural effects of human milk odour in the human neonate, considering different types of response measures in a feeding or non-feeding context. Further, an overview of the current knowledge of odorant composition and factors influencing milk odour is provided by summarizing results from analytical studies using olfactometry, and addressing changes in milk odour due to storage, lactational stage, and maternal dietary intake of odorous substances. We finally highlight some issues for future research.
Student Engagement and School Burnout in Finnish Lower-Secondary Schools: Latent Profile Analysis
2016
Self-ratings of behavioural engagement, cognitive engagement and school burnout were used in person-centred analyses to identify latent profiles among 2,485 Finnish lower-secondary school students. Three profiles were identified: high-engagement/low-burnout (40.6% of the sample), average-engagement/average-burnout (53.9%), and low-engagement/high-burnout (5.5%). Another sample of lower-secondary school students was used to validate the 3 profiles. The factors most strongly associated with the high-engagement/low-burnout profile of lower-secondary school students’ were high levels of support from teachers and family, good academic performance, and lack of truancy. The study indicated that te…
Selective breeding for endurance running capacity affects cognitive but not motor learning in rats
2012
The ability to utilize oxygen has been shown to affect a wide variety of physiological factors often considered beneficial for survival. As the ability to learn can be seen as one of the core factors of survival in mammals, we studied whether selective breeding for endurance running, an indication of aerobic capacity, also has an effect on learning. Rats selectively bred over 23 generations for their ability to perform forced treadmill running were trained in an appetitively motivated discrimination-reversal classical conditioning task, an alternating T-maze task followed by a rule change (from a shift-win to stay-win rule) and motor learning task. In the discrimination-reversal and T-maze …
Pair interactions in online assessments of collaborative problem solving: case-based portraits
2018
This exploratory case study focuses on how pairs of students can build a shared understanding and acquire collaborative problem-solving (CPS) practices during an online assessment of CPS skills, which is seen in the context of the CPS construct, in a symmetrical and asymmetrical task type. Even though CPS is widely recognised as a core twenty-first-century competency, its nature is not yet well understood. Also, until recently, most of studies have focused on the individual’s solution to a problem or on the skills individuals bring into a problem-solving space. This study extends from an individual- to group-level focus in CPS, emphasising the role and quality of the social aspects in CPS p…
Las formas cotidianas de la felicidad y sus mandatos: Pedagogías del pensamiento positivo, trabajo docente y subjetividad en el neoliberalismo contem…
2020
Positive thinking constitutes one of the great traditions that lead to the idea of the subject as an entrepreneur of himself and is perhaps one of the best that has successfully condensed cultural, political, social and pedagogical processes linked to reflection on well-being in this historical time. The teaching work is especially moved by the pregnancy of these perspectives that challenge the pedagogical field and the education workers as ?agents of change, or at least one more school available to give the discussion on well-being and happiness (yours and the students?) is celebrated and encouraged. In this article, I intend to understand what is being built as pedagogical discourses abou…
Grappling with the Oral Skills: The learning processes of the low-educated adult second language and literacy learner
2013
This paper focuses on the learning processes in L2 literacy classes in the Netherlands, discussing specifically possible influences of the learning processes during the practice of the oral skills. To achieve a better understanding of the students’ spoken language development, classroom processes of six adult L2 literacy classes were observed during a period of eight months and students were pre- and post-assessed. In comparing the classes, notable differences in gain scores in morphosyntactic features as well as aspects of relevance and coherence in discourse surfaced. In order to explain these differences, certain factors were examined in relation to learner characteristics, classro…
Organizational Wellness Modeling
2009
The aim of the present paper is to establish certain mathematical models for organizational wellness as well as to create some wellness optimization problems applicable to any type of organization (including universities) that might be mathematically solved resorting to aspects of operational research of mathematical analysis. The results obtained associated with a mathematical apparatus enable one to perform analyses, comparisons, interpretations, predictions. All of us have, consciously or not, a genuine curiosity in creating and shaping organizational wellness. This concept represents a highly topical issue since professional activity, irrespective of its field, holds a very significant …
