Few studies have addressed vocabulary quality in developing writing skill in Spanish. Even less addressed it within the Chilean educational system. The specific objective of this study was to characterize, using a comprehensive set of indicators, the quality of the vocabulary produced by Chilean 4th grade students. Based on a national writing survey, a sample of 2056 texts written by 685 students was collected (narrative, persuasive, and informative texts). Current literature defines lexical quality as a composite of diverse factors that, while distinct, are interrelated. To represent the properties of the vocabulary, a set of indicators were selected: (a) lexical diversity; (b) lexical sophistication; and (c) lexical density. Using multilevel modeling (students and schools as levels 1 and 2) to explain a global writing score we found that diversity was a significant determinant for narrative and persuasive texts, density was a significant determinant for the three genres and sophistication was a significant determinant for narrative and expository text. In addition, indicators related to gender and socioeconomic conditions were only significant determinants of narrative stories. The parts of speech most often used also varied according to the purpose of each text. In all genres, words had a short extension and were very sensitive to the input presented in the stimuli. These results imply a significant challenge to this education system: how to promote the development of vocabulary in all children in order to support language learning. 相似文献

Development of professional expertise is the process of continually transforming the repertoire of knowledge, skills and attitudes necessary to solve domain-specific problems which begins in late secondary education and continues during higher education and throughout professional life. One educational goal is to train students to think more like experts and approach the mastery of a subject as an expert would. Helping students to develop professional expertise and evaluating whether classrooms are conducive to the development of expertise is difficult and time-consuming. At present, there is no instrument that measures all the core classroom factors that influence specifically the development of professional expertise. This paper describes the development and validation of an instrument that measures the extent to which educators create a Supportive Learning Environment for Expertise Development, the SLEED-Q. A sample of 586 secondary school students (14–18 years-old) was used for validation. Both exploratory and confirmatory factor analyses were carried out. Examination of the fit indices indicated that the model seemed to fit the data well, with the goodness-of-fit coefficients being in recommended ranges. The SLEED-Q, consisting of seven factors with 30 items, the SLEED-Q has potential as an instrument for examining how conducive learning environments are to development of professional expertise in secondary school settings. The implications of the results and potential paths for future research are considered. 相似文献

How to facilitate learning by novices (students) on their road to expertise has attracted the attention of a vast number of researchers in cognitive and educational psychology as well in the field of learning and instruction. Although many studies have investigated the phenomenon of expertise development, the implications of the findings for instruction are scattered throughout the literature. This article reports the results of a systematic literature review of 37 studies on expertise development. Using Tynjälä's Integrative Pedagogy Model as an organising framework, the implications for educational practice described in these studies are presented as 10 instructional principles. This study takes a step towards translating expertise development research into guidelines for instruction. Implications for future research are discussed. 相似文献

Policies for science, technology and innovation: Translating rationales into regional policies in a multi-level setting 总被引：4，自引：0，他引：4
Departing from a number of theoretical perspectives from which rationales for science, technology and innovation (STI) policy can be extracted, this paper discusses three questions. First, what rationales for public intervention can be derived from different economic theories, including theories usually associated with spatial dynamics and territorial relationships? Second, what policy instruments or policy-mixes can be associated with the various rationales? Third, what do these theories and associated rationales tell us about the territorial level or levels at which STI policies can usefully be designed and implemented? 相似文献

This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin’ it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use. 相似文献

Narrative media health messages have proven effective in preventing adolescents' substance use but as yet few measures exist to assess perceptions of them. Without such a measure it is difficult to evaluate the role these messages play in health promotion or to differentiate them from other message forms. In response to this need, a study was conducted to evaluate the Perception of Narrative Performance Scale that assesses perceptions of narrative health messages. A sample of 1185 fifth graders in public schools at Phoenix, Arizona completed a questionnaire rating of two videos presenting narrative substance use prevention messages. Confirmatory factor analyses were computed to identify the factor structure of the scale. Consistent with prior studies, results suggest a 3 factor structure for the Perception of Narrative Performance Scale: interest, realism, and identification (with characters). In addition, a path analysis was performed to test the predictive power of the scale. The analysis shows that the scale proves useful in predicting intent to use substances. Finally, practical implications and limitations are discussed. 相似文献
