Our aim was to assess the impact of an invented spelling programme conducted in small groups on children’s written language acquisition in Portuguese. We expected the experimental group to have better post-test results than the control group in spelling and reading. Participants were 160 preschool-age children who were randomly divided into an experimental and a control group. Their age, cognitive ability, knowledge of letters and phonological abilities were controlled. Children’s spelling and reading were evaluated in a pre- and a post-test. In-between, experimental group participated in an invented spelling programme in small groups and the control group in story readings. The experimental group showed better results in spelling and reading in the post-test than the control one. Different dynamics occurred in the small groups which had different impacts on children’s acquisitions. These results provide empirical support for the proposal that invented spelling should be incorporated into early literacy instruction. 相似文献

With music being one of the key elements of radio, and plurality one of the most important principles of public service, this article’s central argument is that one of the missions of public radio is to foster musical elements produced in the country’s national language. Focusing on traditional musical genres of the Portuguese-speaking countries, we will analyze the role of music in public radio by selecting specific musical shows focused on the Lusophone world. In order to determine the presence and impact of Lusophony in national stations, music will be the common thread for a reflection on how multicultural their programming strategies are able to be. 相似文献

Salt decay is one of the harshest, most frequent, and more complex types of decay of porous materials in built heritage, including natural stones, ceramics, and mortars. In this article, we address the mechanism of thermal expansion, which is one of the least studied, yet most controversial, of those proposed over time to explain salt decay. We present a review of scientific literature on the topic, followed by a study of the effects of thermal expansion on a specific material, the well-known Ançã limestone. The study included experimental measurement of the linear thermal expansion coefficient of the Ançã, both in its natural state and with varying contents of sodium chloride, sodium sulphate, or sodium nitrate. The results show that this coefficient: (i) is significantly higher when the stone is contaminated with salt; and (ii) scales approximately with the amount of salt contained in the stone pores, regardless of the type of salt. Based on these results and on modelling of damage modes at the microscopic and macroscopic levels, respectively, we conclude that thermal expansion can cause powdering, disaggregation, or other types of decay consisting of internal loss of cohesion. However, it is not likely to cause exfoliation of salt-loaded layers. 相似文献

The Individualised Education Programme (IEP) is a fundamental document that describes all educational responses to the additional support needs of students, setting up the guideline for their learning and developmental experiences. Specifically, the IEP goals represent the personal destination translated into desirable behaviours and skills that will enable students with additional support needs to meet their educational and functional needs. This paper analysis the quality of the 2497 IEP goals established for 135 Portuguese students with additional support needs and their fit to the students’ level of severity and educational level. The quality of IEP goals was measured using the Revised IFSP/IEP Goals and Objectives Rating Instrument and the content was categorised in reference to the International Classification of Functioning, Disability and Health, version for Children and Youth. Findings showed that goals are generally poorly written, particularly in terms of their measurability and that their quality decreases as students’ progress in education. Results also showed that IEP goals for students with a highly individualised curriculum do not attend to their needs of more functional contents. The results are discussed in terms of their implications for teacher training. 相似文献

ABSTRACTUniversities seek to promote entrepreneurship through effective education approaches, which need to be in permanent evolution. Nevertheless, the literature in entrepreneurship education lacks empirical evidence. This article discusses relevant issues related to promoting entrepreneurship in the software field, based on the experience of a 15-European Credit Transfer and Accumulation System course. This course seeks to instil in the students the recognition of the need to reconcile technical and business visions, organisational and commercial aspects, most of which have never been addressed previously. A series of semi-structured interviews made it possible to obtain relevant insights about the teaching–learning process underlying this course and its evolution over a seven-year period. Materials related with this course have been analysed, namely guidelines produced by the teachers and deliverables produced by the students. This article discusses the dimensions that were identified as fundamental for promoting entrepreneurship skills in the field of software, namely teamwork, project engagement, and contact with the market. 相似文献

The oral arguments of 12th grade students while solving tasks related to evolution are examined. Two groups (N = 45), taught by the same teacher, were studied during a complete teaching sequence. The paper focuses on data from the last sessions, devoted to solving problems in small groups, problems related to different dimensions of the evolutionary model. Data include video recordings, the students’ written productions and the researcher (first author) field notes. The objective is to examine the process of articulation of students’ argumentation practices with their use of evolutionary models. The results show that participants were able to apply notions such as common ancestors, radiation, or gradualism to different contexts. The arguments required the articulation of evolution notions with argumentative practices as coordinating evidence with claims at different epistemic levels. The influence of the teacher’s strategies in the students’ role is discussed. 相似文献

This study tested the effectiveness of two strategy-focused interventions aimed at promoting fifth and sixth graders’ opinion essay writing. Over 12 weekly 90-min lessons, two groups of 48 and 39 students received, respectively, planning and sentence-combining instruction, which followed the Self-Regulated Strategy Development (SRSD) model. These intervention groups were compared with a practice control group of 39 students receiving standard writing instruction. The following main findings were noteworthy: (a) planning and sentence-combining instruction enhanced planning and sentence-construction skills, respectively; (b) both interventions increased opinion essay quality and text length; (c) planning instruction enhanced not only discourse-level writing but also some sentence- and word-level aspects of composition; (d) sentence-combining instruction enhanced not only sentence- and word-level writing but also some discourse-level aspects of composition; (e) after instruction, there was a correlation between self-efficacy and writing quality in both intervention groups; and (f) planning, but not sentence-combining, instructional effects generalized to summary writing. 相似文献

Body composition is a physiological variable associated with physical activity and, in some cases, is related to athletic performance. Our objectives were to describe the body composition of participants in three distinct Paralympic sports and to compare the values of body density and estimated body fat obtained from the Paralympic athletes on the National Team by air-displacement plethysmography (ADP) and by the anthropometric method (skinfolds (SFs)). The sample consisted of 70 volunteers of both genders. The body composition of the volunteers was evaluated using the ADP in a Bod Pod® and seven SFs. There were no significant differences between the values obtained by ADP and SF for body fat percentage (p?=?.58) and body density (p?=?.49). Analysis by Bland–Altman plots showed mean differences of 0.56?±?4.94 (?9.12–10.23) and ?0.0017?±?0.0113 (?0.024–0.020) for body fat percentage and body density, respectively. In conclusion, body composition analyses of Paralympic athletes by the ADP and SF methods show similar results, and ADP should be used as the first option when available. When the use of ADP is not possible, estimating body density and fat percentage by SF is a viable alternative for Paralympic athletes when future comparisons will use the same analysis method. 相似文献
