Julia Crespo Comesa?a  Margarita Pino Juste 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2007,24(1):205-218

The objective of this study is to offer a view on the different environmental factors that affect health (sound, light, colour, temperature) in the design, planning and organization of school premises. To achieve this, the authors first outline the problems leading to unhealthy situations. They subsequently analyse all the building and planning factors behind those problems based on a study carried out in the Autonomous Community of Galicia, in the north west of Spain. The study took as its subject all secondary-level education centres built in Galicia since the Spanish Basic Act on the Educational System (LOGSE) was passed by the Spanish Parliament in 1990. To conclude, the article offers a number of guidelines to be taken into account when designing a school environment.  相似文献   

Secondary science students’ beliefs about class discussions: a case study comparing and contrasting academic tracks     

Diane Silva Pimentel  Katherine L. McNeill 《International Journal of Science Education》2016,38(12):2047-2068

The dialogue that occurs in science classrooms has been the subject of research for many decades. Most studies have focused on the actual discourse that occurs and the role of the teacher in guiding the discourse. This case study explored the neglected perspective of secondary science students and their beliefs about their role in class discussions. The study participants (N?=?45) were students in one of the three differentially tracked chemistry classes taught by the same teacher. Findings about the differences that exist among students from different academic tracks are reported. While it seems that epistemological beliefs focusing on content are common for the students in this study, the students' social framing in the different tracks is important to consider when teachers attempt to transition to more dialogic forms of discourse. Some key findings of this study are (a) students’ beliefs that science is a body of facts to be learned influenced the factors they deemed important for whole-class discussion, (b) students from the lower-level track who typically were associated with lower socioeconomic status were more likely to view their role as passive, and (c) students’ comfort level with the members of the class seemed to influence their decisions to participate in class discussions.  相似文献   

Science Classroom Interactions and Academic Language Use with English Learners     

Tiberio Garza  Margarita Huerta  Tracy G. Spies  Rafael Lara-Alecio  Beverly J. Irby  Fuhui Tong 《International Journal of Science and Mathematics Education》2018,16(8):1499-1519

Academic language is critical for English learners (ELs) to succeed in the science classroom. This study analyzed the instructional practices centered around academic language taking place in eight, fifth-grade classrooms during a grant-funded project. Observational data collected through a classroom observation instrument were analyzed to describe and compare the instructional practices occurring in treatment and control classrooms when teachers and students used academic language. Our findings show both treatment and control classrooms using academic language during the course of the intervention study, but the instruction looked markedly different in each setting. These differences provide valuable insight for practitioners and researchers concerned with the academic language development of ELs in science classrooms.  相似文献   

AILEM Programme: a long‐term intervention to promote literacy learning in low‐performing primary schools in Chile     

Malva Villalón Bravo Corresponding author  Margarita Silva  Tonia Razmilic  Stanley L. Swartz 《Early Years: An International Journal of Research and Development》2005,25(2):97-111

After one year of implementation, this paper describes a programme designed to support literacy learning in low performing schools from poor sectors in Santiago, Chile. School‐based intensive training on theory and practice of a literacy learning framework for classroom instruction and long‐term support were used to impact the achievement of students from disadvantaged families in 16 kindergarten classrooms and 16 1st‐grade classrooms in nine primary schools. Preliminary results showed an improvement in learning achievement positively related to level of implementation of the literacy instruction framework in the classrooms and teachers' perception of an improvement in their knowledge and classroom practices. Although findings from this study cannot support definite conclusions, because of the lack of experimental conditions, they provide relevant information for future experimental studies on how to meet the literacy learning needs of children from disadvantaged backgrounds.  相似文献   

Three‐Year‐Olds’ Reactions to a Partner's Failure to Perform Her Role in a Joint Commitment          下载免费PDF全文

Ulrike Kachel  Margarita Svetlova  Michael Tomasello 《Child development》2018,89(5):1691-1703

When children make a joint commitment to collaborate, obligations are created. Pairs of 3‐year‐old children (N = 144) made a joint commitment to play a game. In three different conditions the game was interrupted in the middle either because: (a) the partner child intentionally defected, (b) the partner child was ignorant about how to play, or (c) the apparatus broke. The subject child reacted differently in the three cases, protesting normatively against defection (with emotional arousal and later tattling), teaching when the partner seemed to be ignorant, or simply blaming the apparatus when it broke. These results suggest that 3‐year‐old children are competent in making appropriate normative evaluations of intentions and obligations of collaborative partners.  相似文献

Gender bias in IQ-discrepancy and post-discrepancy definitions of reading disability     

Share DL  Silva PA 《Journal of learning disabilities》2003,36(1):4-14

The present study investigated the hypothesis that the higher prevalence of reading disability (RD) often observed among boys is partly an artifact of gender bias in the prediction of reading from IQ. The relevant regression statistics derived from a sample of more than 900 children revealed a statistically significant intercept bias. Predicted reading scores for boys were systematically overestimated, thereby inflating IQ-reading discrepancies; the converse was found for girls. When defined separately for girls and boys, severe underachievement in reading was found to be equally prevalent in both genders and, furthermore, was associated with qualitatively and quantitatively similar patterns of deficits. Because the bias arose from general differences between boys and girls in reading score distributions (a lower mean and greater variance for boys) rather than from differences in IQ scores, gender bias poses a potential threat not only to traditional IQ-discrepancy definitions but also to post-discrepancy definitions that are based solely on reading score cutoffs. Future classification criteria for RD need to take heed of the possibility that when the distributions of reading scores for boys and girls are not identical, performance cutoffs designating low achievement that are based on data pooled from both genders are likely to result in the overidentification of boys with RD and the underidentification of girls with RD.  相似文献

The organization and temporal properties of appetitive behavior in rats     

Kathleen M. Silva  William Timberlake 《Learning & behavior》1998,26(2):182-195

In the presence and absence of an externalinterfood clock stimulus (a sequence of flashing lights), rats showed a multimodal behavior pattern during successive quarters of interfood intervals (IFI) ranging from 12 to 192 sec. Responses near the feeder peaked before and just after food presentations, whereas locomotion remote from the feeder peaked toward the middle of the IFI. The temporal patterns of nosing in the feeder and remote locomotion were scalar (the time at which a response peaked in the IFI was proportional to the IFI length), whereas the patterns of postfood feeder-directed behavior, rearing, and pawgrooming were time bound (peaking at a fixed time after food, regardless of IFI length). Responses varied in their control by the external clock stimulus. During the last half of the IFI, rats nosed in the feeder more with an external clock, but only at intermediate IFIs. During the first quarter of the IFI, rats pawgroomed more with an external clock, but only at the longest IFI. The general sequence of responses during the interfood clock was consistent with the view that food delivery engages an organized sequence of search states that are expressed through a variety of responses.  相似文献   

Exploring features for the automatic identification of user goals in web search     

Mauro Rojas Herrera  Edleno Silva de Moura  Marco Cristo  Thomaz Philippe Silva  Altigran Soares da Silva 《Information processing & management》2010

Queries submitted to search engines can be classified according to the user goals into three distinct categories: navigational, informational, and transactional. Such classification may be useful, for instance, as additional information for advertisement selection algorithms and for search engine ranking functions, among other possible applications. This paper presents a study about the impact of using several features extracted from the document collection and query logs on the task of automatically identifying the users’ goals behind their queries. We propose the use of new features not previously reported in literature and study their impact on the quality of the query classification task. Further, we study the impact of each feature on different web collections, showing that the choice of the best set of features may change according to the target collection.  相似文献
