In this study we propose a theoretical construct (called rhetorical competence) that represents the ability of readers to detect, understand, and use the linguistic cues or discourse markers that texts contain. We measure one of the three postulated components of rhetorical competence (knowledge of textual integration
markers), assessing whether readers correctly interpret these markers while reading. The influence of this skill on reading
competence is examined in a correlational study of 185 sixth-grade pupils (aged 11–12 years) using different assessment materials
(a standardized test and an academic text) and reading conditions (habitual and aided). Multiple regression analyses of the
data indicate that knowledge of textual integration devices makes a significant independent contribution to expository text
comprehension under most assessment conditions when the effects of working memory, prior knowledge, and word recognition skills
are controlled. 相似文献

Abstract This article describes Project ASTER III (Active Science Teaching Encourages Reform), a science professional development program for early elementary teachers, which is based on the premise that people learn best by doing. Very few professional development programs focus on early childhood teacher development and how best to integrate informal science centers into teaching. In ASTER III, development teams—consisting of university scientists, science educators, K‐3 teachers, and educators from a hands‐on science museum—developed 5E lesson plans aligned with the Ohio Academic Content Standards and the National Science Education Standards in conjunction with the museum’s exhibits. This study explores the impact of the ASTER III model on teacher perceptions about the role and effect informal science museum visits have on subsequent teaching and student learning. 相似文献

When dealing with complex conceptual systems, low-prior- knowledge learners develop fragmentary and incorrect understanding. To learn complex topics deeply, these learners have to (a) monitor understanding to detect flaws and (b) generate explanations to revise and repair the flaws. In this research we explored if the detection of a flaw in understanding does lead to the generation of a revising explanation or, alternatively, if there is some independence between the two processes. In two studies participants with low prior domain knowledge learned about plate tectonics from a multimedia presentation. In Study 1 participants in two conditions received support for detection and their performance was compared to that of participants in two control conditions, one receiving no support and another one receiving support for both detection and revision. Performance on retention, transfer, and distortions revealed that the conditions with support for detection were not different from that with no support. The condition with support for both detection and revision was significantly better than all others. In Study 2 participants thought aloud while studying from the presentation. Self-generated detections were not correlated with revising explanations or with performance on retention or transfer measures. Overall, the results indicate that the detection of flaws in understanding does not necessarily lead to the generation of explanations to repair the flaws, meaning that this latter process is very difficult to execute and calls for instructional support. 相似文献

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage. 相似文献

In this essay, I use the rhetorical approach of generic criticism to analyze issues management campaigns: instances of public relations discourse in which an organization makes explicit efforts to influence public policy. There are striking similarities among contemporary organizations’ issues management campaigns in terms of their organizing principle, situational requirements, and substantive and stylistic characteristics. Using a structurational perspective, I illustrate the genre rules (Yates &; Orlikowski, 1992) that serve as the medium and outcome of this discourse. Throughout the essay, I employ the University of Minnesota's recent attempt to increase its public funding during a period of institutional transition to explicate the genre rules. This article outlines a framework for the analysis of issues management campaigns and provides a first step toward the development of a structuational theory of their genre rules. Moreover, it argues that a rhetorical approach to the study of such organizational communication creates fresh insights and understandings in an area traditionally dominated by a focus on effects. 相似文献

The purpose of this study was to cross-validate a model of relationships among social-contextual factors, individual differences, and intrinsic motivation in adolescent students enrolled in required courses (E. Ferrer-Caja & M. R. Weiss, 2000) with an independent sample of students taking elective courses. Female and male high school students (N = 219) completed measures of motivational climate, teaching style, perceived competence, self-determination, goal orientation, and intrinsic motivation. Motivated behavior was assessed by teachers who rated the students on effort and persistence in class activities. First, the authors used structural equation modeling to examine model invariance between the original and the new samples, which yielded a lack of equivalence. Next, the authors examined several alternative theory-based models using the elective sample. The results indicated that the data were best represented by a model that separated social-contextual factors, individual factors, intrinsic motivation, and motivated behaviors. The strongest predictors of intrinsic motivation were task-goal orientation and perceived competence. These results are discussed from both theoretical and methodological perspectives. 相似文献

The study was an investigation of the usefulness of 50 variables in predicting the academic performance of 86 students readmitted to Bronx Community College following academic suspension. The variables included scores on the City University of New York placement tests, the Maudsley Personality Inventory, and the Survey of Study Habits and Attitudes. Other variables included 8 educational history items, 20 biographical items, and students' opinions about the contribution of 12 factors to their previous academic failure. The criterion measure was the academic performance (pass or fail) in the re‐entry semester. The principal conclusions to be derived from this study are that, for the population of academic failures characterized by average high school achievement and average scholastic aptitude, specific academic skills are important, past academic record seems unimportant, and a general factor called incentive seems important in the attainment of passing grades upon readmission. 相似文献

Goldfish were trained to obtain food in a four-arm maze placed in a room with relevant spatial cues. Four experimental conditions were run: allocentric, egocentric, egocentric + allocentric, and control. Relative to controls, all groups were able to solve the different tasks with high accuracy after 1 week of training. Subsequent transfer tests revealed place and response strategies for allocentric and egocentric groups, respectively, and both types of strategies for the ego-allocentric group. Moreover, the allocentric group showed the capacity to choose the appropriate trajectory toward the goal, even from novel starting points, presumably by using the distal cues as a whole. The results suggest that, in addition to using egocentric strategies, goldfish are able to solve spatial tasks on the basis of allocentric frames of reference and to build complex spatial cognitive representations of their environment. 相似文献

This paper provides a systematic review of the literature on knowledge management (KM) in small and medium enterprises (SMEs) and SME networks. The main objective is to highlight the state-of-the-art of KM from the management point of view in order to identify relevant research gaps. The review highlights that in recent years the trend of papers on the topic is growing and involves a variety of approaches, methodologies and models from different research areas. The vast majority of papers analysed focus on the topic of KM in the SME while there are only few papers analysing KM in networks populated by SMEs. The content analysis of the papers highlights six areas of investigation from which were derived ten research questions concerning three perspectives: the factors affecting KM; the impact of KM on firm’s performance; the knowledge management systems. 相似文献

Colleges and universities are adopting learning communities to increase student learning and build cohesion. As learning communities grow in popularity, institutions need to invest in faculty development (Oates, 2001) and understand faculty experiences (Mullen, 2001). The University of Hartford created a program that prepared faculty for collaborative teaching in first-year learning communities. Faculty learned to engage in collaborative behaviors, to think outside disciplinary borders, and to employ a specific template as a heuristic for course development. Results of focus group research about the faculty experience and the impact of the experience on their pedagogy are summarized.Catherine B.

She and her coauthors are affiliated with the University of Hartford, West Hartford, CT. Her special interests include nineteenth and twentieth century literature, curriculum reform, pedagogy, and international education. Robert L. Duran, Professor in the School of Communication, who earned his M.A. at West Virginia University and Ph.D. at Bowling Green State University, is a specialist in program evaluation, evaluation research, and research methods.
