The aim of this research is to identify the difficulties experienced by secondary school students (aged 15–16) with the critical reading of newspaper articles with scientific content. Two newspaper critical reading activities in relation to the study of various scientific contents were designed and carried out in two schools (61 students in total), one with a student population from a medium to high social and economic bracket and the other with students from a medium to low social and economic bracket. These activities were designed taking into account the phases of the reading process: before, during and after reading. In order to analyse the difficulties ‘Elements of science critical reading’ were identified on the basis of the ‘Elements of reasoning’ of Paul and Elder and the categories proposed by Bartz C.R.I.T.I.C. questionnaire and a scale was drawn up. The results show that the activities designed were useful in helping students to read critically. We also rated very positively the instrument created to assess the students' answers: the scale based on the performance indicators of Paul and Elder. This instrument enabled us to detect the aspects of critical thinking where students have the most difficulties: identifying the writer's purpose and looking for evidence in a text. It was also shown that the stance taken in the articles also had an influence on the results. 相似文献

Parental involvement is interpreted as a key form of support that can contribute to the establishment of inclusive practices in schools, but this can be difficult in sparsely populated areas. Using ethnographic methods of participant observation, informal conversations and document analysis, this article therefore focuses on family involvement practices in two small rural schools in Aragón (Spain) that carry out creative teaching practices as a way to encourage parental participation. Our data show that teachers promote parental involvement using strategies such as acceptance, expression and communication in school. These strategies seem to be negotiated in each situation based on the values prioritised by the teachers as a result of their interaction within the context they find themselves in. Factors such as family mobility, dispersion of homes and sociocultural status appear to condition these strategies. 相似文献

Introduction:
The enzyme 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) catalyzes the conversion of the hormonally inactive cortisone to active cortisol, thus facilitating glucocorticoid receptor activation in target tissues. Increased expression of 11β-HSD1 in adipose tissue has been associated with obesity and insulin resistance. In this study, we investigated the association of two 11β-HSD1 gene (HSD11B1) polymorphisms with the metabolic syndrome (MetS) and its characteristics in the Bosnian population.Materials and methods:
The study included 86 participants: 43 patients diagnosed with MetS and 43 healthy controls. Subjects were genotyped for two HSD11B1 gene polymorphisms: rs846910: G>A and rs45487298: insA, by the high resolution melting curve analysis. Genotype distribution and an influence of genotypes on clinical and biochemical parameters were assessed.Results:
There was no significant difference in the mutated allele frequencies for the two HSD11B1 gene polymorphisms between MetS patients and controls. In MetS patients, no significant associations between disease-associated traits and rs45487298: insA were found. Regarding rs846910: G>A variant, heterozygous patients (G/A) had significantly lower systolic (P = 0.017) and diastolic blood pressure (P = 0.015), lower HOMA-IR index (P = 0.011) and higher LDL-cholesterol levels (P = 0.049), compared to the wild-type homozygotes. In the control group, rs45487298: insA polymorphism was associated with lower fasting plasma insulin levels (P = 0.041), lower homeostasis model assessment insulin resistance (HOMA-IR) index (P = 0.041) and lower diastolic blood pressure (P = 0.048). Significant differences between rs846910: G>A genotypes in controls were not detected. Haplotype analysis confirmed the association of rs45487298: insA with markers of insulin resistance in the control subjects.Conclusions:
Our results indicate that a common rs45487298: insA polymorphism in HSD11B1 gene may have a protective effect against insulin resistance. 相似文献5.

This article analyses the knowledge, perception and participation of university students in NGOs. The social group analysed has a very positive perception towards volunteering as well as a life situation and preparation that, in theory, facilitates their participation in such activities. However, their effective participation is much lower than the levels shown by potential volunteers who would like to participate. We have identified two elements that stand between the possibility and reality: the lack of information and the time available. In this sense, universities appear as institutions capable of connecting the needs and demands of NGOs and students. 相似文献

ABSTRACT This article focuses on the relevance that aesthetic practices play extending parental involvement and influence in school contexts in Spain. One rural, one urban and one peri-urban school have been included in the research. Participant observation and interviews were the main means of data production. In the results all the different schools promoted parents’ participation. However, differences in aesthetic practices and experiences were found. Parental involvement was developed in schools in different ways in relation to local contextual conditions and the salient characteristics of the geographic spaces the schools belonged to. Practical aesthetic knowledge produced multiple strategies of action. 相似文献

Podríamos decir que un educador es una «inteligencia natural» que moviliza sus recursos cognitivos para enseñar lo mejor posible. ¿Hasta dónde ha llegado hay la ciencia en ese ambicioso objetivo de copiar la mente humana? ¿Puede simularse la mente natural de un profesor experto y competente y situarla en un programa que eduque a través del ordenador? Este artículo introduce el tema y hace un balance de las posibilidades. 相似文献

AbstractThis article provides the foundation and describes the pedagogical and functional design of a PLE within the Just4Me project. This environment integrates tools and functionalities to support learning across and throughout life.The main goal of the pedagogical design is to encourage self-managed learning, regardless of whether it occurs in formal or informal settings. It aims to integrate learning experiences developed within different contexts. 相似文献
