Research Findings: The Early Childhood Environment Rating Scale–Revised (ECERS-R) is widely used to evaluate the quality of early childhood education and its association with child development. However, the psychometric properties of the ECERS-R are not well established. Consequently, in this study we tested 3 different factor solutions of the ECERS-R using models sourced from the existing literature (featuring 1-, 2-, and 3-correlated-factor solutions) and applying confirmatory factor analysis to data from the epidemiological sample of the Embu Pre-school Mental Health Study (n = 1,292 children). Alternative measures of child education quality (such as teacher-to-child ratio) were also analyzed. The confirmatory factor analysis returned good fit indices for both the unidimensional and 3-correlated-factor solution models. Practice or Policy: This study showcases different applications of the ECERS-R, both the full and shortened versions. These findings are particularly important for improving ECERS-R guidelines for researchers, professionals, and policymakers. 相似文献

Current engineering education challenges require approaches that promote scientific, technical, design and complementary skills while fostering autonomy, innovation and responsibility. The European Project Semester (EPS) at Instituto Superior de Engenharia do Porto (ISEP) (EPS@ISEP) is a one semester project-based learning programme (30 European Credit Transfer Units (ECTU)) for engineering students from diverse scientific backgrounds and nationalities that intends to address these goals. The students, organised in multidisciplinary and multicultural teams, are challenged to solve real multidisciplinary problems during one semester. The EPS package, although on project development (20 ECTU), includes a series of complementary seminars aimed at fostering soft, project-related and engineering transversal skills (10 ECTU). Hence, the students enrolled in this programme improve their transversal skills and learn, together and with the team of supervisors, subjects distinct from their core training. This paper presents the structure, implementation and results of the EPS@ISEP that was created in 2011 to apply the best engineering practices and promote internationalisation and engineering education innovation at ISEP. 相似文献

This article presents a case study on how goods scarcity, both natural and artificially created, was used along with censorship to control the Portuguese public's access to information during the 1930s and 1940s. Even though the dictatorship that ruled Portugal from 1933 relied on a censorship apparatus that prevented the publication and broadcast of many pieces of national and international news, the research presented in this article demonstrates how the regime took advantage of the Spanish Civil War and World War II to increase restrictions on the circulation of information, justifying this through the artificially created scarcity of paper and radio frequencies. Furthermore, this article also describes how a third type of scarcity—that of electricity—also restricted listeners' access to radio broadcasts, which led many Portuguese to make sacrifices in order to listen to updated news. 相似文献

This article introduces a collection of original papers and research project reports considering the history of the BBC foreign-language services prior to, and during, the Second World War. The communication between the British government and foreign publics by way of mass media constituted a fundamental, if often ignored, aspect of Britain's international relations. From the 1930s onwards, transnational broadcasting, that is, broadcasting across national borders, became a major element in the conduct of Britain's diplomacy, and the BBC was employed by the government to further its diplomatic, strategic and economic interests in times of rising international tension and conflict. A review of the literature on the BBC's foreign-language broadcasts sets the stage for the presentation of the articles that compose this special issue of Media History. 相似文献

Many of the current approaches used in teaching and learning in engineering education are not the most appropriate to prepare students for the challenges they will face in their professional careers. The active involvement of students in their learning process facilitates the development of the technical and professional competencies they need as professionals. This article describes the organisation and impact of a mini-conference and project work – the creation of a software product and its introduction in the market – aimed at the development of professional competencies in general and writing skills in particular. The course was evaluated by assessing the students’ perception of the development of a number of professional competencies through a questionnaire completed by 125 students from two consecutive year groups. The results indicate that the project work and the mini-conference had a positive impact on students’ perceptions of the development of professional competencies. 相似文献

Background : Advance organizers are instructional materials that help students use previous knowledge to make links with new information. Short animation movies are a possible format and are well suited for physics, as they can portray dynamic phenomena and represent abstract concepts. Purpose : The study aimed to determine guidelines for the construction of an instructional short animation movie, with the role of an advance organizer. A film was created in order to evaluate the effectiveness of the approach, making part of a physics lesson and concerning the subject ‘moment of a force’. Sample : The study took place in a Brazilian school in the city of Arapoti, in the south region of the country. Thirty-eight students participated, having an average age of 16 and following the third year of high school. Design and methods : Criteria drawn from a literature review directed the construction of the movie and the lesson. Data were collected using pre- and post-tests; registers of oral comments were also done during the class. The post-test included open-ended questions, allowing students to write remarks concerning the lesson and the animation. Conclusions : The article describes steps and guidelines to orient the process of designing an animation movie with the role of advance organizer. Data indicated that the movie facilitated the construction of links between pre-existent knowledge and the new information presented in the lesson. The proposed methodology can be considered a valid framework to derive similar approaches. 相似文献

Background: Scientific excellence is one of the most fundamental underpinnings of medical education and its relevance is unquestionable. To be involved in research activities enhances students' critical thinking and problem-solving capacities, which are mandatory competences for new achievements in patient care and consequently to the improvement of clinical practice. Purposes: This work aimed to study the relevance given by Portuguese medical students to a core of scientific skills, and their judgment about their own ability to execute those skills. Methods: A cross-sectional study was conducted on students attending the first, fourth and sixth years of medical course in the same period. An assessment istrument, exploring the importance given by Portuguese medical students to scientific skills in high school, to clinical practice and to their own ability to execute them, was designed, adapted and applied specifically to this study. Results: Students' perceptions were associated with gender, academic year, previous participation in research activities, positive and negative attitudes toward science, research integration into the curriculum and motivation to undertake research. The viewpoint of medical students about the relevance of scientific skills overall, and the ability to execute them, was independently associated with motivation to be enrolled in research. Conclusions: These findings have meaningful implications in medical education regarding the inclusion of a structural research program in the medical curriculum. Students should be aware that clinical practice would greatly benefit from the enrollment in research activities. By developing a solid scientific literacy future physicians will be able to apply new knowledge in patient care. 相似文献

Abstract We assessed the agreement between maximal oxygen consumption ([Vdot]O2max) measured directly when performing the 20-m shuttle run test and estimated [Vdot]O2max from five different equations (i.e. Barnett, equations a and b; Léger; Matsuzaka; and Ruiz) in youths. The 20-m shuttle run test was performed by 26 girls (mean age 14.6 years, s = 1.5; body mass 57.2 kg, s = 8.9; height 1.60 m, s = 0.06) and 22 boys (age 15.0 years, s = 1.6; body mass 63.5 kg, s = 11.5; height 1.70 m, s = 0.01). The participants wore a portable gas analyser (K4b2, Cosmed) to measure [Vdot]O2 during the test. All the equations significantly underestimated directly measured [Vdot]O2max, except Barnett's (b) equation. The mean difference ranged from 1.3 ml · kg?1 · min?1 (Barnett (b)) to 5.5 ml · kg?1 · min?1 (Léger). The standard error of the estimate ranged from 5.3 ml · kg?1 · min?1 (Ruiz) to 6.5 ml · kg?1 · min?1 (Léger), and the percentage error ranged from 21.2% (Ruiz) to 38.3% (Léger). The accuracy of the equations available to estimate [Vdot]O2max from the 20-m shuttle run test is questionable at the individual level. Furthermore, special attention should be paid when comparisons are made between studies (e.g. population-based studies) using different equations. The results of the present study suggest that Barnett's (b) equation provides the closest agreement with directly measured [Vdot]O2max (cardiorespiratory fitness) in youth. 相似文献

The aims of this study were: (1) to observe participation in moderate-to-vigorous physical activity (MVPA) during school recess periods; (2) to determine the relative importance of physical activity during recesses to overall daily physical activity; and (3) to examine differences in physical activity between the sexes during unstructured recess periods. The participants were 22 school children (10 boys, 12 girls) aged 8?–?10 years (mean = 8.9, s = 0.7) in the third and fourth grades. Daily totals for the physical activity variables were calculated by summing the values for each hour of 14?h of physical activity measurements (08:00 to 22:00?h). Recess times (minutes) were as follows: morning 10:30 to 11:00?h and afternoon 15:30 to 16:00?h. We did not differences between boys and girls in daily total accelerometer counts or the overall time spent in MVPA. However, girls were significantly (P <?0.05) more involved (38%) in MVPA during recess time than boys (31%). Participation in MVPA during recess contributes significantly more (P <?0.05) for girls (19%) than boys (15%) to the total amount of physical activity suggested by international health-related physical activity guidelines, while the percentage of time engaged in MVPA during recess time at school accounts for a small amount of the daily MVPA (6% for boys and 8% for girls). The results of this study suggest that school recess time is an important setting to promote MVPA and contributes to daily physical activity in young children, especially in girls. 相似文献

ABSTRACTThis article presents an analysis of the right to education in Brazil in light of the growing number of Brazilian families practicing homeschooling. The debate is recent in Brazil. Here we present an analysis of international literature on homeschooling, Brazilian literature on the right to education, and an appraisal of lawsuits against Brazilian families for teaching their children at home. In light of truancy regulations and the evolution of a right to education in Brazil, homeschooling creates legal and political challenges. 相似文献
