El diseño de unidades didácticas en L2 mediante tareas: Principios y desarrollo

El enfoque didáctico basado en tareas, que se presenta en los trabajos de Breen y de Candlin en este mismo número, cuenta en este artículo con un desarrollo detallado, que permitirá al lector aplicarlo al diseño de unidades didácticas concretas para la enseñanza de una L2, con una especificación de los pasos y de los niveles a seguir y con una guía para integrar estos diseños en el marco del modelo curricular adoptado en nuestro país desde la nueva Ley de Ordenación General del Sistema Educativo.     

Summation and transfer of negative occasion setting

Two experiments examined the summation and transfer of negative occasion setting in serial feature negative (X→A?/A+) and negative patterning discriminations (X→A?/X+/A+) in a discrete-trial operant task with rats. With both discrimination procedures, negative occasion setting transferred readily (but not perfectly) to cues trained as targets in another similar discrimination procedure, but not to cues that were separately trained. Furthermore, with both discrimination procedures, the negative occasion-setting powers of features from two individual discriminations summed, both when those features were trained with the same targets and when they were trained with different targets. After negative patterning discriminations, in which the feature (X) cues were separately reinforced, this summation of negative occasion setting occurred despite the concomitant summation of the features’ excitatory control in the absence of an explicit target cue. These data, which replicated and extended previously reported data from Pavlovian feature negative procedures, are discussed in the context of hierarchical, generalization, and network models of discrimination learning.

Schooling of Children with Rare Diseases and Disability in Europe

ABSTRACT

Inclusive education of disabled students has been promoted in European disability policies. However, the transition process from more segregated system is slow. The purpose of this study was to provide an insight about different types of schooling of disabled children affected by a rare disease across Europe and to evaluate their and caregivers’ well-being. We analysed data from a cross-sectional study (BURQOL-RD) of persons with rare diseases that cause intellectual and/or physical disability: Prader-Willi syndrome, fragile X syndrome, three types of mucopolysaccharidosis and Duchenne muscular dystrophy. The sample consisted of 359 children aged 6–17 and 269 caregivers from eight European countries. Results showed differences between countries in proportion of students placed in special schools, which are still valid option in countries such as Germany, France or UK. Within the inclusive education modalities, lack of special support for disabled students was observed especially in low-income countries. No association between the type of schooling and quality of life was observed, but the subjective caregivers’ burden seems to be higher in special schools. The study shows existent differences in implementation of inclusive education in Europe. More research is needed in the field of rare disease disability and educational needs.     

Studying mathematics problem-solving classrooms. A comparison between the discourse of in-service teachers and student teachers

In the article we compare the approaches of 3 in-service teachers and 3 student teachers when they tried to solve a verbal arithmetic problem in the classroom. Each interaction was studied using a System of Analysis that takes into account the cognitive processes involved in the solution of a mathematic problem and describes the interaction at different levels showing what is done and to what degree teachers and/or pupils are responsible for what is done. The results of the study suggest that both groups of teachers are different in how they direct the student’s attention toward the essential aspects implied in the resolution of word problem. On the one hand, the in-service teachers guaranteed students’ understanding of the problem before dealing with the solution, while students teachers only did so when pupils committed errors. On the other hand, the in-service teachers allowed a high level of student participation, while student teachers took a more prominent role so children’s participation was lower.     

Images of Science Linked to Labwork: A Survey of Secondary School and University Students

This paper presents findings about the images of science drawn upon in laboratory work, by upper secondary and university students, in academic streams with a science focus. Data were collected through four written questions, administered to a total of 368 students. The questions all required students to comment on laboratory investigations carried out by research scientists or by science students. We show that students' reasoning has an epistemological and an ontological dimension, and that it often differs significantly from accepted perspectives on the nature of science. The issue for teaching appears to be showing students what counts (and what does not count) as appropriate reasoning in actual situations. In other words, explicit teaching about the various relationships that can exist between theory and data would transform labwork towards a more critical process that involves making and justifying decisions.     

Bildungserfolg und adoleszente Abl?sung bei S?hnen aus t??rkischen Migrantenfamilien

Many studies have shown that young males of Turkish descent are disadvantaged in terms of educational opportunity in Germany. In this, the lower educational successes of children from migrant families are neither simple effects of lower levels of social capital nor of lower educational aspiration. With the aim of tracing unexplained mechanisms of the intergenerational transmission of educational chances, the interdependency of educational success or failure of young men of Turkish descent and adolescent processes of detachment and family relations were reconstructed using an intergenerational research design. This shows the major importance of parents?? processing of their immigration experiences in the context of discrimination and disadvantage, the effects of this on the parent-child-relationship, especially in adolescence, and the impact of intergenerational dynamics on the realization, processing and effects of differing educational aspirations and careers.     

Avoidance of interspecific mating in female Syrian hamsters is stronger toward familiar than toward unfamiliar heterospecific males

Adult Syrian hamster females (Mesocricetus auratus) learn to discriminate against familiar heterospecific males (Turkish hamster, M. brandti). We investigated whether females learn to avoid any heterospecific male after exposure to just one heterospecific male. We predicted that, after being exposed to one heterospecific male, a female would avoid mating not only with that familiar male but also with any unfamiliar heterospecific male. We exposed females to a heterospecific male across a wire-mesh barrier for 8 days and then paired the female with (a) that same heterospecific male or (b) an unfamiliar heterospecific male. Females exhibited lordosis faster and for a longer duration toward the unfamiliar than toward the familiar heterospecific male. However, females were similarly aggressive toward familiar and unfamiliar heterospecific males. Perhaps exposure to stimuli from several heterospecific males (a likely scenario in the wild) would result in females behaving similarly toward familiar and unfamiliar heterospecific males.
