Communicating the new chemistry in 18th-century Portugal: Seabra’s Elementos de Chimica     

Ana Carneiro  Maria Paula Diogo  Ana Simões 《Science & Education》2006,15(7-8):671-692

In this paper, we analyse the aims, contents and impact of Seabra’s two-volume textbook – Elementos de Chimica (Elements of Chemistry) – published in 1788 and 1790. Seabra’s Elements of Chemistry does not conform to the characteristics usually ascribed to textbooks by traditional historiography, and in particular to textbooks published in the peripheries. Marking the arrival of the new chemistry in Portugal, in a period in which many still resisted Lavoisier’s chemistry, this textbook was a state of the art account written in Portuguese, interspersed with critical evaluations, original comments and novel contributions. Despite being the only Portuguese chemistry textbook written during this period, it had hardly any readers, even among its natural audience at the University of Coimbra.  相似文献   

Commentary: Development of Perception-Action Systems and General Principles of Pattern Formation     

M. T. Turvey  Paula Fitzpatrick 《Child development》1993,64(4):1175-1190

Our commentary on this special issue devoted to Developmental Biodynamics: Brain, Body, and Behavior Connections is divided into 3 main sections. The first section is an overview of the individual contributions. 5 major themes are identified: (1) inappropriateness of computational treatments of development and the need for more biologically and physically relevant treatments; (2) significance of tailoring muscular to nonmuscular forces in developing movement coordination; (3) importance of spontaneous movements as exploratory and formative mechanisms; (4) influences of action capabilities on the development of perception capabilities, and vice versa; (5) applications of methods and techniques of nonlinear dynamics to developmental processes. In the second section, we provide a synopsis of current ways of thinking about prototypical developmental processes, namely, pattern formation and pattern differentiation, in various classes of physical and biological systems. It is suggested that efforts to understand the progressive formation and differentiation of patterns in terms of very general principles provide a valuable resource of concepts and methods for students of child development. In the third section, hypotheses about the development of perception-action systems are generated from juxtaposing the themes and conjectures of this special issue with general principles of pattern formation. The hypotheses suggest the possibility of a pattern formation or dynamics approach to child development as an alternative to the conventional approaches emphasizing maturation (nativist), specific learning experiences (empiricist), cognitive stages (Piagetian), and strategies of encoding and retrieval (information processing).  相似文献   

The Quality of Work Life in NAEYC Accredited and Nonaccredited Early Childhood Programs     

Paula Jorde Bloom 《Early education and development》1996,7(4):301-317

This study assessed differences in the work environments of NAEYC accredited and nonaccredited centers. The sample included 5,008 directors, teachers, and support staff who worked in 60 accredited and 320 nonaccredited child care centers in 33 states. Individuals completed the Early Childhood Work Environment Survey assessing their perceptions of different organizational practices. Data were aggregated using the center as the unit of analysis. The results revealed that there were notable differences between accredited and nonaccredited programs relating to the quality of work life for staff. In 10 dimensions of organizational climate, there were statistically significant differences between accredited and nonaccredited programs. The four dimensions which together accounted for the greatest variation in differences were innovativeness, goal consensus, opportunities for professional growth, and clarity. Statistically significant differences were also registered in staffs level of job commitment, staff turnover, and teachers' current and desired levels of decision- making influence.  相似文献   

The relationship between motivation to read and reading comprehension in chilean elementary students     

Orellana  Pelusa  Melo  Carolina  Baldwin  Paula  De Julio  Samuel  Pezoa  José 《Reading and writing》2020,33(10):2437-2458

This study examined the role of reading motivation in reading comprehension achievement of 1070 Chilean third, fourth, and fifth-grade students enrolled in public and private schools. Students were assessed in Spanish reading comprehension and were administered the Motivation to Read Profile from Gambrell, Palmer, Codling and Mazzoni (1996), at the beginning and end of the school year. Results showed that motivation to read at the beginning of the school year was significantly associated with gains in reading comprehension skills. When disaggregating motivation into self-concept and value of reading, only self-concept of reading significantly predicted gains in reading comprehension. Moderation analyses showed that students that started the year with lower reading comprehension and higher motivation to read, had significantly better reading comprehension at the end of the school year, than their peers who started with lower reading motivation. The pedagogical implications are discussed.

Predictors of primary school teachers’ knowledge about developmental dyscalculia     

Paula Sousa  Irene Cadime 《欧洲特需教育杂志》2017,32(2):204-220

Developmental dyscalculia is a specific learning disability that is described as a heterogeneous and persistent cognitive disorder. Given the need to detect and intervene as early as possible to minimise its effects, teachers’ knowledge about symptoms, characteristics and effective intervention strategies in dyscalculia is essential. Given the lack of research about this topic and measures to evaluate teachers’ knowledge, this study aims to present a literature-based measure to evaluate knowledge about developmental dyscalculia and to investigate the predictors of this type of knowledge. Data were collected from a sample of 175 primary school teachers. The measure presented adequate psychometric properties. Teachers’ personal characteristics such as age and gender did not predict their knowledge about dyscalculia. Being a Special Education teacher predicted a higher knowledge of intervention strategies in dyscalculia and having heard about dyscalculia predicted higher knowledge about not only intervention strategies but also dyscalculia characteristics. The data are discussed, and suggestions for further studies are presented.  相似文献   

Positing Organizational Effectiveness as a Second-Order Construct in Hong Kong Higher Education Institutions   总被引：1，自引：0，他引：1  

Kwan  Paula  Walker  Allan 《Research in higher education》2003,44(6):705-726

The study examines the relative importance of the various organizational effectiveness dimensions in higher education institutions by positing organizational effectiveness as a second-order construct. Based on the findings of a survey administered to university academics in Hong Kong universities, the second-order structure of organizational effectiveness was supported. The findings reflected that the student-related dimensions were not considered as important as the dimensions related to faculty employment and satisfaction and suggested the disproportionate influence of the governing body on universities in Hong Kong.  相似文献   

Student engagement: rhetoric and reality     

Paula Baron  Lillian Corbin 《高等教育研究与发展》2012,31(6):759-772

Recently, there has been much interest in higher education literature and policy on the concepts of student engagement and disengagement. While most academic writings recognise the significance of student engagement, they have tended to concentrate on it in relation to academic activities. Increasingly, universities are ‘cascading’ down the need to improve student engagement to schools and ultimately to individual academics. This article asserts that ideas about student engagement in the university context are often fragmented, contradictory and confused. Even the meaning of the term ‘student engagement’ is uncertain. Further, while government and universities urge attention to student engagement, many of their actions, it may be argued, have contributed to greater student disengagement. Relying on the available literature, we argue that the student experience as a whole is the key to engagement and, thus, efforts to re-engage students cannot be successful until a ‘whole-of-university’ approach is adopted.  相似文献   

A structural model of the effects of preschool attention on kindergarten literacy     

Jaime L. Dice  Paula Schwanenflugel 《Reading and writing》2012,25(9):2205-2222

Factors that lead to poor achievement in literacy are evident prior to a child beginning kindergarten. In the present study, we examined the importance of including attention in a model for predicting emergent literacy in prekindergarten and subsequent reading abilities in kindergarten. The sample was 250 children attending public prekindergarten and kindergarten. Structural equation modeling was used to test our hypothesis that children??s early literacy skills mediate the relationship between preschoolers?? attention and kindergarten decoding abilities. Using early literacy as a mediator between early attention and later decoding provided a good model fit. Results suggest that attention was integral to the fit of the model and that attention in preschool is related to the development of early literacy skills above and beyond the contribution of maternal education to these skills. The implication of our study is that attention in early childhood should be considered an important part of literacy development.  相似文献

Effective formative e-assessment of student learning: a study on a statistics course     

Paula Hodgson  Marco Y.C. Pang 《Assessment & Evaluation in Higher Education》2012,37(2):215-225

The process of formative assessment in universities has the potential to engage students in reflection and to take greater ownership of their learning. We report on a study involving 104 students taking a statistics course in a degree programme in rehabilitation science in Hong Kong. The assessment strategy was redesigned to include a weekly online formative assessment activity for 10 weeks. In this case, it was observed that there was a high participation rate across weeks. An end-of-course online survey was conducted to explore the learning experiences during formative assessment of the cohort, and students reported high satisfaction with the process, particularly how this contributed to a change in their learning approach. Students not only showed regular commitment of time on tasks but also took active steps to find answers for themselves and with their peers.  相似文献
