ResumenMediante tareas de clasificación de segmentos-palabra, se investiga la evolución infantil en la reflexión sobre el propio idioma (capacidad gramatical). Los datos demuestran que esta evolución pasa por largos períodos—entre ocho y once años—de estrategias semántico-pragmáticas y, por tanto, inmaduras gramaticalmente. 相似文献

ResumenEl propósito de este estudio fue diseñar un modelo válido para la adquisición de unos adecuados hábitos de estudio, basado en una combinación de estrategias de autorregulación y técnicas de estudio. Se procedió mediante un diseño exploratorio de línea de base múltiple, con un único sujeto que incluía: a) fase de pretest, b) primera fase de intervención, en la que se introdujeron las estrategias de autorregulación, c) segunda fase de intervención o de introducción de las técnicas de estudio, y d) fase de postest. El resultado fue un cambio experimental y terapéuticamente significativo en los hábitos de estudio y en las conductas exponentes de: tiempo de estudio, desatención, y velocidad y comprensión lectoras, las calificaciones experimentaron un ascenso progresivo. Estos cambios se mantuvieron y consolidaron en el seguimiento, las estrategias de autorregulación se han mostrado útiles para aumentar la probabilidad de ocurrencia de la conducta deseada y disminuir la de la no deseada. 相似文献

The main purpose of this study is to analyze whether quality of preschool classrooms relates to 4- and 5-year-old children developmental outcomes. The study was conducted in 60 classrooms in Porto Metropolitan Area, Portugal. Children (N?=?215) were evaluated in the literacy, math, and behavior domains. Preschool quality was assessed through classroom observations using the ECERS-R and the Early Language and Literacy Classroom Observation. Global classroom quality although relatively low, predicted children’s literacy skills and behavior but not math skills. Quality of language and literacy environment was not consistently related to child outcomes. Mother educational level stood out as consistently predicting most of child developmental outcomes. The relevance of these results is discussed considering the Portuguese educational scenario, in the realm of an international context. 相似文献

This paper reports a classroom-based study involving investigation activities in a university numerical analysis course. The study aims to analyse students' mathematical processes and to understand how these activities provide opportunities for problem posing. The investigations were intended to stimulate students in asking questions, to trigger their thinking processes, to promote their ability to investigate and to support them in learning numerical analysis' concepts and procedures. The results show that the investigations provided opportunities for students to experience mathematical processes, including posing questions, formulating and testing conjectures and, to some extent, proving results. They also provide some understanding about the role of problem posing in these processes. Posing questions occurred mainly in an implicit way, in the interpretation of tasks and in identifying regularities, analysing graphs and testing cases. The conjectures were often based on pattern identification or data manipulation, and the students tended to accept them without testing or proving. The students also proposed alternative formulations for the initial questions and posed new problems from their explorations and attempts to refine previous conjectures. 相似文献

Systems for searching the Web based on thematic contexts can be built on top of a conventional search engine and benefit from the huge amount of content as well as from the functionality available through the search engine interface. The quality of the material collected by such systems is highly dependant on the vocabulary used to generate the search queries. In this scenario, selecting good query terms can be seen as an optimization problem where the objective function to be optimized is based on the effectiveness of a query to retrieve relevant material. Some characteristics of this optimization problem are: (1) the high-dimensionality of the search space, where candidate solutions are queries and each term corresponds to a different dimension, (2) the existence of acceptable suboptimal solutions, (3) the possibility of finding multiple solutions, and in many cases (4) the quest for novelty. This article describes optimization techniques based on Genetic Algorithms to evolve “good query terms” in the context of a given topic. The proposed techniques place emphasis on searching for novel material that is related to the search context. We discuss the use of a mutation pool to allow the generation of queries with new terms, study the effect of different mutation rates on the exploration of query-space, and discuss the use of a especially developed fitness function that favors the construction of queries containing novel but related terms. 相似文献

ABSTRACTHigher education (HE) research often draws on a range of qualitative research approaches. However, some methods developed in other fields are underutilised in HE research, even though they could be of great use for answering particular kinds of research questions, or for involving students more actively in the research process. In this article, we draw on a study that piloted different methodological approaches to explore students’ conceptions of good teaching and effective learning at university. The participants in our study included 33 high achieving international, Māori, Pacific Island, and (other) local students enrolled in Humanities subjects. Our study used photovoice as a visual data collection approach in conjunction with more traditional methods of data collection: open-ended focus group questions and critical incident technique. In this article, we review the photovoice literature, which is mostly from outside HE. Then, we describe our study, discussing the students’ responses to photovoice, and the different kinds of data it elicited. We note that, while most students expressed appreciation of the photovoice approach, some also found it restrictive and challenging in some respects. We conclude, photovoice offers a useful methodological addition to HE research, while noting, as with all data collection approaches, researchers need to be mindful of its limitations. 相似文献

AbstractUsing data from Ithaka S?+?R US Faculty Survey 2015, the current study examined the influence of disciplinary differences and experience levels as well as their interactions on scholars’ attitudes toward print and electronic materials. While results of 3?×?5 factorial ANOVA procedure indicated both disciplinary membership and experience played a role in scholars’ attitudes, effect size indicated disciplinary membership played a more crucial role. Significant findings include rising popularity of electronic formats across examined groups. 相似文献

This study examines the current state of research in academic procrastination. Neutralization theory is then explored with emphasis on its applicability to academic information seeking and use procrastination. Finally, results of qualitative semi-structured interviews illustrating the applicability of neutralization theory on students' information behavior are presented along with the implications and areas for further research. 相似文献
