Modes of differentiation in children’s writing construction     

Clotilde Pontecorvo  Cristina Zucchermaglio 《European Journal of Psychology of Education - EJPE》1988,3(4):371-384

In this paper we aim at analyzing the modes of differentiation in children’s writing development during the presyllabic phase that, in the theoretical framework developed by Ferreiro and Teberosky, comes before the discovery of sound correspondance. Seventeen Italian children were interviewed seven times during the implementation of research on «Educational Continuity» between «scuola materna» and primary school. We first examine how minimum quantity and internal variation rules appear in Italian children as organizing principles for controlling quantity and quality of writing, and as necessary conditions for the differentiation process. Starting from this, it is possible to find two differentiation modes in writing; aformal one, and a mode in which some type ofexternal referent is used (meaning or object features). For most children the two modes are alternatives, and passing from one to another is a possible but not necessary step. The external group (which is older) has significantly less quantity repertoire than the formal one: this can explain why looking for an external point of reference can be an outcome of the child’s formal research for differentiating writings.  相似文献   

Academics’ perceptions of the impact of internal quality assurance on teaching and learning     

Orlanda Tavares  Cristina Sin  Pedro Videira  Alberto Amaral 《Assessment & Evaluation in Higher Education》2017,42(8):1293-1305

Internal quality assurance systems are expected to improve the institutions’ core mission of teaching and learning. Using data gathered through an online survey, distributed in 2014/2015, to the teaching staff of all Portuguese private and public higher education institutions, this paper examines the impact of internal quality assurance systems on teaching and learning from the perspective of academics. Findings suggest that Portuguese academics feel that, despite the positive contribution of internal quality assurance towards an increased awareness of teaching quality issues at their institutions, the practical effects of these systems have been more related to increasing bureaucracy than to substantive improvements in teaching and learning. The use of information with a view to improvement and teaching staff involvement in the development of quality assurance were found to induce positive changes in teaching and learning, in academics’ perceptions. Based on the findings, the paper makes recommendations for institutional practice.  相似文献   

Internal quality assurance systems in Portugal: what their strengths and weaknesses reveal     

Orlanda Tavares  Cristina Sin  Alberto Amaral 《Assessment & Evaluation in Higher Education》2016,41(7):1049-1064

In Portugal, the agency for assessment and accreditation of higher education has recently included in its remit, beyond programme accreditation, the certification of internal quality assurance systems. This implies lighter touch accreditation and aims to direct institutions towards improvement, in addition to accountability. Twelve institutions have already undertaken the certification, and both self-assessment and external assessment reports are available. Based on the qualitative analysis of the nature of institutional strengths and weaknesses highlighted in these evaluation reports, the paper aims to understand whether the identified strengths and weaknesses are related to procedural and organisational matters or to cultural change (values and beliefs), in turn offering an insight into the quality culture(s) which characterise higher education institutions in Portugal. Findings suggest that the quality culture of the analysed institutions is somewhere between responsive and reactive. Overall, all reports dwell more on the prioritisation of formal and structural procedures, both regarding strengths and weaknesses. External reports point towards more weaknesses related to stakeholders’ participation. Both aspects are more frequent in polytechnics than in universities. These findings suggest that polytechnics are more reactive, whereas universities are more responsive. Therefore, accountability apparently continues to be, for the time being, a more pressing concern than improvement.  相似文献   

The contribution of vocabulary knowledge and semantic orthographic fluency to text quality through elementary school in Catalan     

Cristina Castillo  Liliana Tolchinsky 《Reading and writing》2018,31(2):293-323

Building a text is a multidimensional endeavor. Writers must work simultaneously on the content of the text, its discursive organization, the structure of the sentences, and the individual words themselves. Knowledge of vocabulary is central to this endeavor. This study intends (1) to trace the development of writer’s vocabulary depth, their vocabulary fluency in writing, and the features of the text they produce (productivity, lexical richness, and text structure) through elementary school and (2) to determine the contribution of the writer’s performance and the text features to the quality of the text. One hundred and eighty bilingual Spanish/Catalan speakers from first, third, and sixth grade took part in the study. They participated in three researcher-created tasks; a synonyms/antonyms task to orally assess vocabulary depth; a semantic orthographic fluency task to examine their vocabulary fluency in writing; and a text writing task to evaluate text quality. Data was analyzed using structural equation modeling in order to examine the relationship between the target writer’s performance and the text features of the written compositions, and the externally evaluated text quality. Results revealed that both writer’s performance on vocabulary depth and semantic orthographic fluency and text features improved with school level. However, the capacity to establish meaning relations between words contributed more directly to the quality of texts than the speed to find words with a specific phonographic correspondence. External evaluation of text quality was more variable for younger students than for older students and was affected by school level mediated by writer performance and text features.  相似文献   

Adolescent Mothers and Their Children's Early School Performance     

Robert C. Pianta  Cristina L  pez-Hern  ndez  Julie E. Ferguson 《Early education and development》1997,8(4):377-387

This study examined differences in child-mother interaction, classroom adjustment during kindergarten, and retention in kindergarten between 41 first-born children of adolescent mothers (18 years old or younger at the time of the child's birth) and 88 first-born children of adult mothers (20 to 24 years old at the time of the child's birth). Maternal education was included as a covariate in comparisons. The children of adolescent and adult mothers were generally indistinguishable in areas of classroom adjustment, retention in kindergarten, and child-mother interaction when mothers' education was considered. Results are discussed in terms of implications for research and policy.  相似文献   

Assessment of integration method for displacement determination using field accelerometer and geophone data     

F. Lamas-Lopez  Y. J. Cui  S. Costa D’Aguiar  N. Calon 《浙江大学学报(A卷英文版)》2017,18(7):553-566

A conventional French railway track was instrumented with accelerometers and geophones at three depths: sleeper (surface), interlayer (ITL, z=?0.93 m), and transition layer (TL, z=?1.20 m). A linear variable differential transformer (LVDT) was also used to monitor the displacement at the sleeper level. The recorded data allow the integration method (double for accelerometer and simple for geophone) for displacement determination to be assessed. Several questions need to be addressed prior to the selection of an adequate monitoring system: definition of signal filtering processes, influence on results of the different loading wavelengths, repeatability of measurements, train speed and axle load impact and their ranges of validity for each sensor. It was found that the main frequencies that caused more than 95% of the displacement of the monitored materials are in the low frequency range: <25 Hz for trains running up to 200 km/h. For an intercity train, the low frequencies are normally excited by long wavelengths, for instance, those corresponding to the 1/2 coach distance (λ=13.20 m), the bogies distance (λ=6.3 m), and the axle distance (λ=2.8 m). Comparison between the displacements deduced from the records of accelerometer and geophone and obtained from the records of LVDT shows quite consistent results; the mean displacement amplitudes obtained from accelerometers differ by only 20% from the LVDT records. The train speed does not have a strong effect on the obtained differences between sensors. The embedded sensors also gave consistent displacement results for each analysed depth. Moreover, the displacement amplitudes caused by different axle loads (locomotive or passenger coach) are distinguishable for all sensors at all depths. This validates the integration method used for the displacement determination.  相似文献   

Academics’ and employers’ perceptions about responsibilities for employability and their initiatives towards its development     

Cristina Sin  Alberto Amaral 《Higher Education》2017,73(1):97-111

This paper reports the results of preliminary research into how Portuguese academics and employers perceive the responsibility of different higher education stakeholders—students, teaching staff, higher education institutions, employers, and policy-makers—for developing graduate employability. The study was conducted 8 years after the implementation of the Bologna Process, the reform that placed employability firmly on the agenda of higher education institutions (HEIs) in Portugal. This paper aims to assess the extent to which higher education is held responsible for developing employability, and to characterize the activities undertaken by the two actors to achieve that end. In particular, with respect to academics, we characterize curricular and other changes to study programmes, and, with respect to employers, their participation in activities undertaken by HEIs meant to ease the transition of students to the labour market. The data comes from a survey responded to by 684 Portuguese academics and 64 employers. Academics and employers alike were found to attribute high responsibility for developing employability to higher education, suggesting that the political message of the Bologna Process regarding the relation between higher education and the labour market has been assimilated. However, the activities reported by both types of respondents indicate only an average commitment to developing employability. Here, the low participation of employers in internal institutional activities is noteworthy, suggesting that the recognition of employers as stakeholders in higher education, as advocated by policy-makers, has yet to happen in Portugal.  相似文献   

Civic education and visions of war and peace in the Spanish transition to democracy     

Kira Mahamud Angulo  Tamar Groves  Cecilia Cristina Milito Barone  Yovana Hernández Laina 《Paedagogica Historica: International Journal of the History of Education》2016,52(1-2):169-187

Abstract

This article explores visions of war and peace in the education system during the Spanish transition to democracy. During those years, the Spanish state was faced with the challenge of leaving its authoritarian political past behind and forging a democratic civic culture. As the concepts of war and peace are inextricably linked to those of state and citizenship, they are a useful tool with which to examine changes in civic education. A wide variety of educational sources has been explored, with particular attention to the emotional nature of the depiction of both war and peace. This study reveals two opposing styles. The official discourse demonstrated a factual treatment of war and a tendency to concentrate on international bodies and their actions, when it came to fomenting peace. The treatment of peace in the circles of teachers’ local initiatives was different. First, peace was defined not only as the absence of war but also in terms of social equality and solidarity. Second, there was a conscious effort to get the students involved in opposing war, reinforced by emotionally charged messages regarding its horrors.  相似文献   

Social network perspectives reveal strength of academic developers as weak ties     

Kelly E. Matthews  Andrea Crampton  Matthew Hill  Elizabeth D. Johnson  Manjula D. Sharma  Cristina Varsavsky 《International Journal for Academic Development》2013,18(3):238-251

Social network perspectives acknowledge the influence of disciplinary cultures on academics’ teaching beliefs and practices with implications for academic developers. The contribution of academic developers in 18 scholarship of teaching and learning (SoTL) projects situated in the sciences are explored by drawing on data from a two-year national project in Australia within a case study research design. The application of a social network lens illuminated the contribution of eight academic developers as weak ties who infused SoTL knowledge within teams. Two heuristic cases of academic developers who also linked across networks are presented. Implications of social network perspective are discussed.  相似文献   

Quantifying the interdisciplinarity of scientific journals and fields     

F.N. Silva  F.A. Rodrigues  O.N. Oliveira  L. da F. Costa 《Journal of Informetrics》2013,7(2):469-477

There is an overall perception of increased interdisciplinarity in science, but this is difficult to confirm quantitatively owing to the lack of adequate methods to evaluate subjective phenomena. This is no different from the difficulties in establishing quantitative relationships in human and social sciences. In this paper we quantified the interdisciplinarity of scientific journals and science fields by using an entropy measurement based on the diversity of the subject categories of journals citing a specific journal. The methodology consisted in building citation networks using the Journal Citation Reports^® database, in which the nodes were journals and edges were established based on citations among journals. The overall network for the 11-year period (1999–2009) studied was small-world and followed a power-law with exponential cutoff distribution with regard to the in-strength. Upon visualizing the network topology an overall structure of the various science fields could be inferred, especially their interconnections. We confirmed quantitatively that science fields are becoming increasingly interdisciplinary, with the degree of interdisplinarity (i.e. entropy) correlating strongly with the in-strength of journals and with the impact factor.  相似文献
