Reading together in the classroom. A study of the difference between teacher and student interactions and the requirements of the Ministry of Education in Chile / Lectura conjunta en el aula. Un estudio sobre la distancia entre la interacción profesores alumnos y las prescripciones del Ministerio de Educación Chileno

Abstract

In this article we describe the reading comprehension teaching practices of three Chilean teachers, to contrast them with the proposed guidelines from the Chilean Ministry of Education. To do this, we have analysed what contexts of interaction were created in the classroom and which reading processes were promoted by the questions the students were asked. The results show how the teachers’ practices were closer to the ministerial guidelines when they were asked to create specific contexts of interaction, but deviated from these guidelines when the objective was to promote a reflective and critical understanding of the texts.     

Porosity and surface hardness as indicators of the state of conservation of Mudéjar plasterwork in the Real Alcázar in Seville

Plasterwork, a very typical element of Islamic art, comprises highly artistic decorative elements on wall, arches, and vaults. Due to their gypsum composition, such elements are easily weathered, primarily because of low mechanical strength and slight solubility in water. This work has studied the traditional Islamic plasterwork in the halls and patios of the Mudéjar Palace (13–16th centuries) in the Real Alcázar of Seville. This palace complex was declared a World Heritage Site by UNESCO in 1987. The analysis of its porosity and shore C surface hardness has allowed determination of the mathematical correlation between them. Consequently, future evaluations can merely measure the hardness (a non-destructive test) to estimate the plasterwork's porosity (which reveals its mechanical strength and its degree of weathering). These elements must be maintained in order to prevent the spread of pathologies. In addition to requiring an in-depth knowledge of its materials, application techniques, and properties, to do so also demands simple techniques for regular assessments and criteria to prioritize interventions if they become necessary.     

Relationship between physiological parameters and performance during a half-ironman triathlon in the heat

Abstract

Triathlon is a popular outdoor endurance sport performed under a variety of environmental conditions. The aim of this study was to assess physiological variables before and after a half-ironman triathlon in the heat and to analyse their relationship with performance. Thirty-four well-trained triathletes completed a half-ironman triathlon in a mean dry temperature of 29 ± 3ºC. Before and within 1 min after the end of the race, body mass, core temperature, maximal jump height and venous blood samples were obtained. Mean race time was 315 ± 40 min, with swimming (11 ± 1%), cycling (49 ± 2%) and running (40 ± 3%) representing different amounts of the total race time. At the end of the competition, body mass changed by ?3.8 ± 1.6% and the change in body mass correlated positively with race time (r = 0.64; P < 0.001). Core temperature increased from 37.5 ± 0.6ºC to 38.8 ± 0.7ºC (P < 0.001) and post-race core temperature correlated negatively with race time (r = ?0.47; P = 0.007). Race time correlated positively with the decrease in jump height (r = 0.38; P = 0.043), post-race serum creatine kinase (r = 0.55; P = 0.001) and myoglobin concentrations (r = 0.39; P = 0.022). In a half-ironman triathlon in the heat, greater reductions in body mass and higher post-competition core temperatures were present in faster triathletes. In contrast, slower triathletes presented higher levels of muscle damage and decreased muscle performance.     

On the acquisition of some basic word spelling mechanisms in a deep (French) and a shallow (Spanish) system

An experiment was carried out to compare the time course of the acquisition of two basic spelling mechanisms in Spanish, a shallow system, and French, a deep system. The first was lexical. It relies on the orthographic lexicon, a hypothetical structure containing the orthographic representations of words accessible for word spelling. To evaluate its contribution the participants were asked to spell words of high and low frequency containing phonemes which can take different graphemic values. The second mechanism relies on sub-lexical processes. Its contribution was evaluated asking the participants to spell words containing consistent phoneme-to-grapheme translation pairs which were identical in Spanish and French. Two contrasting predictions were considered, one derived from the Orthographic Depth Hypothesis (ODH, Frost, 2005) and the other from the Self-Teaching Hypothesis (STH, Share, 2004). According to the ODH, the orthographic lexicon should develop more rapidly in French than in Spanish because Spanish spellers can rely on phoneme-to-grapheme translation mechanisms to spell most words, meaning that they do not need to resort to the orthographic lexicon. In contrast, the STH suggests that effective identification of a word gradually generates its orthographic representation. The results revealed that both spelling mechanisms develop far faster in Spanish than in French. The fact that word frequency effects appeared earlier in Spanish than in French, indicating that the orthographic lexicon incorporates words more rapidly in a shallow than in a deep system, is clearly incompatible with the ODH and easier to handle in the context of the STH.     

Comprehensiveness and diversity in secondary compulsory education in andalusia: an unresolved challenge

This article outlines the contradictions and challenges of introducing comprehensive, compulsory education in Andalusia for students up to the age of 16. Following a documenting of the developments, it is argued that while the intention was for a significant, planned reform, it is better characterised as one that is, at best, an improvisation. The article discusses the continuing difficulties that may be attributed to a number of policies of the Conservative government of the day, which allowed the development of two systems of education that were not grounded in concepts of equity and social justice to evolve. The work of John Elliott has been acknowledged as an important influence upon the inquiry that was undertaken and the subsequent analysis of its results. Thus, not only are the results of an action-orientated study reported here, but also there is an extensive set of guiding principles that could enable the reform to be truly actualised.     

Placing Immigrant and Minority Family and Community Members at the School's Centre: the role of community participation

Schools alone cannot reverse the high rates of school failure in the poorest communities in Europe; they need the contributions of the entire community. Coordination between families, the larger community, and the school has proven crucial to enhance student learning and achievement, especially for minority and disadvantaged families. However, families from such backgrounds often participate in their schools only peripherally because the schools take a ‘tourist’ approach, call parents to inform them about school projects and teachers' programmes, or consult them about decisions to be made by professionals, rather than engaging them in their children's education. In contrast, the INCLUD-ED project studied schools across Europe whose students are culturally diverse and from low SES backgrounds; here, the communities are deeply involved in the schools and the students do well academically. This article focuses on three strategies used by these successful schools to engage immigrant and minority community members in more active, decisive, and intellectual ways and thus have greater impact on the school and the students' learning. It also describes some specific practices of involvement grounded in those strategies and the improvements they generate. Though the schools studied use different practices, the three strategies have been found to contribute to a transformative result in all schools: moving minority and disadvantaged families from the periphery of school participation to the centre.

Reduction of disruptive behaviors using an intervention based on the Good Behavior Game and the Say‐Do‐Report Correspondence

Disruptive behavior can waste a great deal of teaching time in the classroom, leading to feelings of frustration in teachers and an increase in academic failure among pupils. Prior research indicates that intervening in these kinds of behaviors improves the classroom atmosphere and facilitates the learning process. With this in mind, the aims of this article are to (a) reduce the incidence of disruptive behaviors such as standing up without the teacher's permission, shouting, fighting, and interrupting the teacher or a fellow classmate, using a combination of the Good Behavior Game (GBG) and Say‐Do‐Report (S‐D‐R) Correspondence training; (b) achieve long‐term maintenance of results following the gradual withdrawal of the intervention; and (c) introduce the GBG in a different educational context than those discussed so far in the empirical literature. The intervention took place with the 15 children of a standard primary classroom (Cycle 1) at a state‐run school in Andalusia (Spain). Using a multiple baseline design across situations, the GBG and Say not‐not Do‐Request not (Sn‐nD‐Rn) Correspondence training were introduced. A significant reduction in the incidence of disruptive behavior was observed, contingent on the respective application of the intervention in each baseline. The combined application of the GBG and the S‐D‐R Correspondence proved to be an effective way of decreasing disruptive behaviors (shouting, interrupting, etc.) in the classroom, and the results were maintained for 1 year following the gradual withdrawal of the treatment. © 2010 Wiley Periodicals, Inc.     

Improving Chilean In-service Elementary Teachers’ Understanding of Nature of Science Using Self-contained NOS and Content-Embedded Mini-Courses

Understanding nature of science (NOS) is considered critical to the development of students’ scientific literacy. However, various studies have shown that a large number of elementary and secondary science teachers do not possess an adequate understanding of NOS. This study investigated how elementary teachers’ understanding of NOS was impacted through a 1-year professional development program in Chile that included NOS instruction as a theme throughout two types of mini-courses in the program. Twelve teachers attended a 1-year development program focused on improving teacher content knowledge and included the instruction of NOS embedded in two self-contained NOS mini-courses (36 h) and two lessons (3 h each) within five science content mini-courses (30 h). The Views of NOS (version D+) questionnaire and interviews were used to assess teachers’ understanding of NOS at the beginning (January) and end of the program (December). Elementary teachers’ understanding of the creative, inferential, and tentative aspect of NOS showed improvement. According to the teachers’ perceptions, the most significant activities for improving their NOS understanding were decontextualized activities in both types of mini-courses (self-contained NOS and science content mini-courses). The implications for professional development programs are also discussed.
