In this mixed methods study, qualitative, quantitative, and single-case methods were combined to provide a comprehensive investigation of teacher and student outcomes following practice-based professional development (PBPD) for self-regulated strategy development (SRSD) in writing. Qualitative observations were used to determine outcomes among the three-fourth grade teachers involved, a nested quantitative model was used to analyze classwide student writing outcomes across 53 students in the three classes, and single case design was used to determine differential outcomes among randomly selected struggling and average writers in each class. PBPD was followed by coaching for differentiation based on student performance and fidelity as teachers taught their students strategies for writing timed imaginary stories (with self as main character), as required by the state writing test. Qualitative results indicated two teachers did not differentiate writing instruction without coaching; one teacher was unresponsive to coaching and did not differentiate instruction. Classwide analysis demonstrated significant growth in writing at the class level for students from baseline to posttesting. Single case design results indicated mixed outcomes among struggling and average writers and instances where instruction was not effective. Teachers indicated high social validity for PBPD and for SRSD; students indicated high social validity for SRSD. Results across the multiple methods illuminate growth and struggles often disguised in group data and are addressed to aid in understanding and enhancing PBPD as well as instruction in SRSD and other evidence-based practices. Limitations and future research directions are discussed. 相似文献

Estimates of young children's time with television: a methodological comparison of parent reports with time-lapse video home observation 总被引:4,自引:0,他引:4
Accurate information on behavior of young children at home is crucial to the study of child development. The present study compared parent diaries of 5-year-old children's time spent with television to concurrent automated time-lapse video observations. In addition, a number of control groups were employed to assess the effects of observational equipment in the homes. The sample consisted of 334 mostly white middle-class families, of whom 106 had observational equipment installed. Results indicated no systematic subject selection of families who were willing to have observational equipment as compared to the controls. In addition, there were no differences in reported viewing behavior between the observed families and controls. Of 3 types of parent estimates of 5-year-old TV viewing, concurrent diaries correlated best with video observation (r = .84) and produced a very small absolute mean time error. Direct parent estimates of typical time spent viewing produced smaller correlations and large overestimates as compared with diaries. 相似文献

Pigeons were trained in a two-choice delayed matching-to-sample task with red and green hues. A brief postsample cue (a vertical or horizontal line) signaled whether the comparison stimuli would be presented or omitted on each trial. Comparison stimuli were always presented following the remember (R) cue, but never following the forget (F) cue or no-cue trials. One group of birds, the differential outcome (DO) group, received reinforcement with a probability of 1.0 for correct responses following one sample stimulus and a probability of 0.2 for correct responses following the other sample stimulus. The nondifferential outcome (NDO) group received reinforcement with a probability of 0.6 for correct responses to either stimulus. The effect of postsample cues was greater for the DO group than for the NDO group. Relative to the NDO group, the DO group displayed higher accuracy on R-cue trials and lower accuracy on F- and no-cue trials. Both tendencies contributed to the enhanced cue effectiveness obtained in the DO group. The results indicate that outcome expectancies are subject to maintenance rehearsal, which comes under the control of postsample R and F cues. They also suggest that maintenance rehearsal may be easier to sustain under DO conditions than under NDO conditions when a memory test is anticipated, but that it may be easier to terminate maintenance rehearsal under DO conditions when a memory test is not anticipated. The results are inconsistent with the assumption that the rehearsal of outcome expectancies is automatic. 相似文献

Task instruction may be presented in many forms. However, training system designers are often forced to depend on intuition when choosing a presentation medium. Though past research has investigated the effectiveness of instructional media types, results have been mixed with no clear recommendations of which medium to use for instruction. An organizational framework for matching the appropriate medium or media to a learning situation is necessary for progress to occur in this research area. Through three experiments, we investigated the attributes of audio and video as instructional media, identified tasks for which we might predict the most beneficial instructional media, and tested our proposed organizational framework by manipulating the difficulty of the task and the complexity of the instructions. Older and younger adults participated in the experiments to help us understand differences in training needs for varying cognitive and perceptual abilities. We provide the basis for a taxonomy of instructional media and task demands, to be added through further research. 相似文献

AbstractOne of the most controversial and significant of contemporary education reforms has been the teacher accountability movement. From this perspective, low-quality teachers and teaching are a major factor behind inadequate school performance, and a lack of accountability and control in schools is a major factor behind the problem of low-quality teachers and teaching. In turn, to advocates of this reform movement, the solution is to centralize control of schools and hold teachers more accountable. Utilizing a sociology of organizations, occupations and work perspective, the objective of this article was to offer a critique of the teacher accountability perspective and movement. This article draws from, and summarizes, the results of a series of empirical research projects on the levels, distribution and effects of accountability and control in American schools. The argument of the article is that the teacher accountability perspective overlooks some of the most important sources and forms of organizational accountability and control that exist in schools and overlooks the ways schools themselves, and in particular the ways they are managed and organized, contribute to the teacher quality problem. As a result, teacher accountability reforms often do not succeed and can have a negative impact on teacher quality and school performance. 相似文献

We report on the origins, development and refinement of an online inventory to help cooperating teachers focus on selected dimensions of their practice. The Mentoring Profile Inventory (MPI) helps quantify important features of both the motivating and challenging aspects of mentoring student teachers and provides results to respondents in a graphic, easy-to-understand and immediate feedback report (14 sub-scales and 3 summary charts). Psychometric properties of the MPI are shown to be robust. Results can be used individually or collectively to facilitate cooperating teacher professional development by providing the opportunity for dialog around a set of common issues. 相似文献

Until the 2002 revision to AACR2 was adopted, cataloging rules for updating loose-leaf publications were orphans—they were excluded from previous Anglo–American rule compilations. To offer guidance to catalogers, over the years the Library of Congress issued a series of rule interpretations and supplemental resources outlining best practices and rules for cataloging loose-leafs. This article chronicles the publication, or lack of practical publication, of cataloging rules for updating loose-leafs and the impact on libraries. Also included is a review of the various organizations instrumental in garnering support for the creation and acceptance of a new paradigm and standards and concepts that would ensure the inclusion of cataloging rules for updating resources. Finally, the impacts on libraries and cooperative organizations resulting from the implementation of the new rules are examined. 相似文献

In fall 2011, the Scott Memorial Library purchased 53 letters belonging to an 1841 graduate of Jefferson Medical College, John Plimpton Green. The library staff transcribed and digitized the letters, creating an online collection in the university's institutional repository, Jefferson Digital Commons. This article will detail the process of transcribing and digitizing the collection along with sharing statistics and the benefits of this project to global researchers. 相似文献

Describes an urban joint-use library's approaches to library programs for homeless children, teens, and adults as well as agencies the library could partner with. Proposes that libraries put more effort into reaching out to the homeless community instead of assuming the normal expectation that people will come to the library. 相似文献

The debate on the role of women in the academic world has focused on various phenomena that could be at the root of the gender gap seen in many nations. However, in spite of the ever more collaborative character of scientific research, the issue of gender aspects in research collaborations has been treated in a marginal manner. In this article we apply an innovative bibliometric approach based on the propensity for collaboration by individual academics, which permits measurement of gender differences in the propensity to collaborate by fields, disciplines and forms of collaboration: intramural, extramural domestic and international. The analysis of the scientific production of Italian academics shows that women researchers register a greater capacity to collaborate in all the forms analyzed, with the exception of international collaboration, where there is still a gap in comparison to male colleagues. 相似文献
