This experimental study reports findings on the effects from a year-long reading intervention providing daily, 50-minute sessions to middle-school students with identified learning disabilities (n = 65) compared with similar students who did not receive the reading intervention (n = 55). All students continued to receive their special education services as provided by the school. Results indicated statistically significant findings favoring the treatment group for sight word reading fluency following intervention. Small effects were found for phonemic decoding fluency and passage comprehension. No other statistically significant differences were noted between groups. The findings suggest that while gains on word reading fluency resulted from the additional reading treatment, accelerating the reading performance of students identified with learning disabilities may be unlikely to result from a one-year, daily intervention provided to students in groups of 10-15. 相似文献

Faculties of education and institutional strategies for knowledge mobilization: an exploratory study
The goal to enhance the impacts of academic research in the ‘real world’ resonates with progressive visions of the role of
universities in society, and finds support among policy makers who have sought to enhance the ‘transfer’, ‘translation’, ‘uptake’,
or ‘valorization’ of research knowledge in several areas of public services. This paper reports on an exploratory study of
the strategies used by selected Canadian and international faculties of education to mobilize research knowledge. Drawing
on data from semi-structured interviews with senior administrators of 13 faculties of education, the analysis reveals several
themes. Academic leaders recognize knowledge mobilization as a desirable institutional mission, but they identify a number
of barriers to greater efforts in this area. Although a number of strategies are employed, changes across multiple organizational
dimensions to encourage and support knowledge mobilization were reported at only two institutions. These results are relevant
to faculty administrators, scholars, and policy-makers interested in understanding the role of academic institutions in the
mobilization of research knowledge to the broader education community. 相似文献

A synthesis and meta-analysis of the extant research on the effects of storybook read-aloud interventions for children at risk for reading difficulties ages 3 to 8 is provided. A total of 29 studies met criteria for the synthesis, with 18 studies providing sufficient data for inclusion in the meta-analysis. Read-aloud instruction has been examined using dialogic reading; repeated reading of stories; story reading with limited questioning before, during, and/or after reading; computer-assisted story reading; and story reading with extended vocabulary activities. Significant, positive effects on children's language, phonological awareness, print concepts, comprehension, and vocabulary outcomes were found. Despite the positive effects for read-aloud interventions, only a small amount of outcome variance was accounted for by intervention type. 相似文献

We present results from a course, “Informal Science Education for Scientists: A Practicum,” co-taught to graduate students
in STEM-related fields by a scientist/engineer and a social scientist/humanist. This course provides a structured framework
and experiential learning about informal science education during a semester-long experience. The data collected across six
years of the course (11 ≤ n ≤ 16 for each) provide strong evidence that the course has been effective in encouraging graduate
students in STEM-related fields to feel more skilled at and confident with informal science education. Details are provided
as to how manipulation of the course structure (i.e. making it project-based, emphasizing understanding audiences, stressing
the iterative nature of design, and increasing evaluation research training) influenced the student outcomes. 相似文献

Implementations of new or major upgrades of existing student information systems require incorporation of new paradigms and
the exchange of familiar routines for new methods. As a result, implementations are almost always time consuming and expensive.
Many people in the field of information technology have identified some of the challenges faced by campuses that attempt to
modify their student services. The work of Gardner et al. (Good work: When excellence and ethics meet. Basic Books, New York, 2001) was used as a model to examine the experiences of those involved in implementations and to
explore how the values of staff members influence the experience of change. Analysis of student information system implementations
at 10 institutions of higher education was conducted. Over a 2-month period, data were gathered from 74 people through a combination
of online surveying, telephone interviews, and completion of a Q-sort instrument based on the published instrumentation of
Gardner et al. (2001). Statistical analyses of the online survey and Q-sort results and use of the SPSS Text Analysis for Surveys 2.0 User’s Guide (SPSS Inc., Chicago, 2006) revealed trends that highlighted the overall perceived importance of communication, collaboration,
and problem solving for implementation success. Analysis also highlighted campus members’ satisfaction level with the implementation
process and how their satisfaction varied depending on if the implementations were completed or still “in process.” Discussion
includes pragmatic recommendations for future implementations. 相似文献

This study examined the association between 3 components of ethnic identity (exploration, resolution, and affirmation) and factors related to family, neighborhood, and individual characteristics. The purpose was to identity factors that are positively associated with adolescent ethnic identity among a sample of 187 Latino adolescents with a mean age of 14.61. The findings suggested that family ethnic socialization was directly associated with exploration and resolution, but not ethnic affirmation. Analyses with moderator variables suggested that associations between family ethnic socialization and ethnic affirmation varied based on parental behaviors and neighborhood characteristics. The results also suggested that ethnic affirmation, but not exploration or resolution, was positively associated with teacher reports of school performance. 相似文献

The response to intervention of English language learners at risk for reading problems 总被引:1,自引:0,他引:1
The response to intervention (RTI) of English language learners identified as at risk for reading difficulties in the fall of first grade was examined at the end of first grade and at the end of second grade. Students at risk for reading problems were randomly assigned to intervention or control groups. Intervention students received supplemental reading intervention daily for 50 minutes in small groups from October to April. Students in the comparison condition received the school's existing instructional program for struggling readers. Criteria were established to determine adequate RTI at the end of first grade and at the end of second grade. The results indicated that more students who participated in the first-grade intervention in either Spanish or English met the established RTI standards than students who did not, and this finding was maintained through the end of second grade. 相似文献

Previous research studies examining the effects of spelling and reading interventions on the spelling outcomes of students with learning disabilities (LD) are synthesized. An extensive search of the professional literature between 1995 and 2003 yielded a total of 19 intervention studies that provided spelling and reading interventions to students with LD and measured spelling outcomes. Findings revealed that spelling outcomes were consistently improved following spelling interventions that included explicit instruction with multiple practice opportunities and immediate corrective feedback after the word was misspelled. Furthermore, evidence from spelling interventions that employed assistive technology aimed at spelling in written compositions indicated positive effects on spelling outcomes. 相似文献

Foams have many useful applications that arise from the structure and size distribution of the bubbles within them. Microfluidics allows for the rapid formation of uniform bubbles, where bubble size and volume fraction are functions of the input gas pressure, liquid flow rate, and device geometry. After formation, the microchannel confines the bubbles and determines the resulting foam structure. Bubbly structures can vary from a single row ("dripping"), to multiple rows ("alternating"), to densely packed bubbles ("bamboo" and dry foams). We show that each configuration arises in a distinct region of the operating space defined by bubble volume and volume fraction. We describe the boundaries between these regions using geometric arguments and show that the boundaries are functions of the channel aspect ratio. We compare these geometric arguments with foam structures observed in experiments using flow-focusing, T-junction, and co-flow designs to generate stable nitrogen bubbles in aqueous surfactant solution and stable droplets in oil containing dissolved surfactant. The outcome of this work is a set of design parameters that can be used to achieve desired foam structures as a function of device geometry and experimental control parameters. 相似文献
