A pedagogical analysis of science textbooks: How can we proceed?   总被引：1，自引：0，他引：1  

Dr Vasilis Koulaidis  Anna Tsatsaroni 《Research in Science Education》1996,26(1):55-71

This paper discusses some of the available frameworks for the pedagogical analysis of school science textbooks. First, it distinguishes between (a) studies which focus on elements of textbooks, such as the content, vocabulary, illustrations used, and the teaching methods promoted; and (b) those which consider the principles that organize the content and the form of presentation. In attempting to consider the sorts of principles that may be used in the studies categorised under (b), two crucial issues are discussed. The first issue refers to the relationship between scientific knowledge and school knowledge, which, as the relevant literature suggests, might not be conceived merely as a simplified “casting” of the scientific structure, but rather should be understood as a complex social process. The second issue explicitly addresses the nature of the pedagogic relationship and the place of the pedagogic text within it. Recent views about the nature of knowledge, it is argued, would suggest a reconceptualisation of the teaching activity, and indicate a model according to which the three elements of the teaching situation-the content, the pupil and the teacher—are seen as being (re)constituted in their articulation within and through the text(book). Thus, for example, what is to be a competent pupil in this approach is a function of the text. On the basis of these considerations, three approaches to the analysis of science textbooks are discussed: the socio-cognitive, the sociolinguistic and the socio-epistemic. The relative merits of the third approach are considered, and some examples are used from Greek science textbooks.  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 Psychometric Characteristics of Choice Items     

Anne R. Fitzpatrick  Wendy M. Yen 《Journal of Educational Measurement》1995,32(3):243-259

This study investigated the psychometric characteristics of constructed-response (CR) items referring to choice and non-choice passages administered to students in Grades 3, 5, and 8. The items were scaled using item response theory (IRT) methodology. The results indicated no consistent differences in the difficulty and discrimination of the items referring to the two types of passages. On the average, students' scale scores on the choice and non-choice passages were comparable. Finally, the choice passages differed in terms of overall popularity and in their attractiveness to different gender and ethnic groups  相似文献   

Physical discipline and children's adjustment: cultural normativeness as a moderator   总被引：2，自引：0，他引：2  

Lansford JE  Chang L  Dodge KA  Malone PS  Oburu P  Palmérus K  Bacchini D  Pastorelli C  Bombi AS  Zelli A  Tapanya S  Chaudhary N  Deater-Deckard K  Manke B  Quinn N 《Child development》2005,76(6):1234-1246

Interviews were conducted with 336 mother-child dyads (children's ages ranged from 6 to 17 years; mothers' ages ranged from 20 to 59 years) in China, India, Italy, Kenya, the Philippines, and Thailand to examine whether normativeness of physical discipline moderates the link between mothers' use of physical discipline and children's adjustment. Multilevel regression analyses revealed that physical discipline was less strongly associated with adverse child outcomes in conditions of greater perceived normativeness, but physical discipline was also associated with more adverse outcomes regardless of its perceived normativeness. Countries with the lowest use of physical discipline showed the strongest association between mothers' use and children's behavior problems, but in all countries higher use of physical discipline was associated with more aggression and anxiety.  相似文献   

Why do students consider dropping out of doctoral degrees? Institutional and personal factors     

Montserrat Castelló  Marta Pardo  Anna Sala-Bubaré  Núria Suñe-Soler 《Higher Education》2017,74(6):1053-1068

Despite the increasing popularity of doctoral education, many students do not complete their studies, and very little information is available about them. Understanding why some students consider that they do not want to, or cannot, continue with their studies is essential to reduce dropout rates and to improve the overall quality of doctoral programmes. This study focuses on the motives students give for considering dropping out of their doctoral degree. Participants were 724 social sciences doctoral students from 56 Spanish universities, who responded to a questionnaire containing doctoral degree conditions questions and an open-ended question on motives for dropping out. Results showed that a third of the sample, mainly the youngest, female and part time students, stated that they had intended to drop out. The most frequent motives for considering dropping out were difficulties in achieving a balance between work, personal life and doctoral studies and problems with socialization. Overall, results offer a complex picture that has implications for the design of doctoral programmes, such as the conditions and demands of part-time doctoral studies or the implementation of educational proposals that facilitate students’ academic and personal integration into the scientific community in order to prevent the development of a culture of institutional neglect.  相似文献

Creative literacy activities promote positive reading attitude in children learning English as a foreign language          下载免费PDF全文

Bonnie Wing‐Yin Chow  Anna Na Na Hui  Barbie Hiu‐Tung Chui 《Journal of Research in Reading》2018,41(2):278-289

This study investigated the effects of creative literacy classroom activities on the acquisition of English as a foreign language. Ninety Chinese second graders were tested on reading attitude and English receptive vocabulary knowledge. They were randomly assigned to either a control group or an experimental group, which engaged in English creative classroom activities for 10 weeks. Repeated measures analyses showed a significant interaction effect for reading attitude, providing empirical evidence that English creative classroom activities can enhance reading attitude. This study extends past research by demonstrating the links between creative activities and reading attitude, as well as highlights the feasibility of incorporating creative literacy activities within foreign language education. This provides a new direction for researchers and educators to develop instructional practices that incorporate a stimulating environment for English‐as‐a‐foreign‐language students. Future longitudinal research could examine whether these benefits can be maintained over a longer period.  相似文献   

Physically abused children's regulation of attention in response to hostility     

Pollak SD  Vardi S  Putzer Bechner AM  Curtin JJ 《Child development》2005,76(5):968-977

The present study examines the effects of early emotional experiences on children's regulation or strategic control of attention in the presence of interpersonal hostility. Abused children's reactions to the unfolding of a realistic interpersonal emotional situation were measured through multiple methods including autonomic nervous system changes and overt behavioral performance. Although physically abused and non-physically abused 4-year-old children did not differ in terms of their baseline levels of arousal, marked differences in physically abused children's regulatory responses to background anger emerged. These data suggest that the emergence of anger leads to increases in anticipatory monitoring of the environment among children with histories of abuse. Results are discussed in terms of risk factors in the development of psychopathology.  相似文献
