Early intervention programs can promote access by providing encouragement for academic preparation, but adequate grant aid may be necessary to ensure access for students who prepare. This study examines the impact of Indiana's Twenty-first Century Scholars Program, an intervention that provides supplemental grant aid and academic support for low-income middle and high school students. Hierarchical logistic regression analyses indicated that 8th grade students who participated in the program were more likely to apply than their peers, indicating that encouragement had a modest influence on preparation. Receiving grant aid had a substantial influence on enrollment, indicating adequate aid is an important aspect of a comprehensive postsecondary encouragement program. 相似文献

A sample of 163 preservice and in-service teachers of deaf and hard-of-hearing students was surveyed on perceptions of the roles of teacher, students, and the classroom. The participants' perceptions were examined utilizing the Survey of Practical Knowledge (SPK) designed and developed by the researcher for the study. The SPK asked the participants to respond to different "images" of teachers, students, and classrooms. Through factor analysis, the following images were generated: the teacher as artisan, the teacher as custodian, the student as subordinate, the student as peer, the classroom as arena, and the classroom as refuge. Beginning education students, graduating education students, novice teachers, and experienced teachers were assessed on their endorsement of those images. Beginning education students tended to view students more as peers than members of the other three groups. In-service teachers were more consistent and flexible in their images than preservice teachers were. Deaf and hard-of-hearing teachers viewed students more as subordinates than did hearing teachers. The dominant view among the study participants conceptualized the teacher as artisan, the students as subordinates, and the classroom as a refuge. 相似文献

We assessed the impacts of a teacher professional development program for public and private kindergartens in the Greater Accra Region of Ghana. We examined impacts on teacher professional well-being, classroom quality, and children’s readiness during one school year. This cluster-randomized trial included 240 schools (teachers N?=?444; children N?=?3,345, Mage?=?5.2) randomly assigned to one of three conditions: teacher training (TT), teacher training plus parental-awareness meetings (TTPA), and controls. The programs incorporated workshops and in-classroom coaching for teachers and video-based discussion groups for parents. Moderate impacts were found on some dimensions of professional well-being (reduced burnout in the TT and TTPA conditions, reduced turnover in the TT condition), classroom quality (increased emotional support/behavior management in the TT and TTPA conditions, support for student expression in the TT condition), and small impacts on multiple domains of children’s school readiness (in the TT condition). The parental-awareness meetings had counteracting effects on child school readiness outcomes. Implications for policy and practice are discussed for Ghana and for early childhood education in low- and middle-income countries. 相似文献

This paper will outline answers to the two central questions regarding improving engineering education: (1) What is the full
set of knowledge, skills, and attitudes that engineering students should possess as they leave the university, and at what
level of proficiency? (2) How can we do better at ensuring that students learn these skills? The suggested answers lie within
an innovative educational framework, the CDIO (conceive–design–implement–operate) Initiative. This initiative will be described
along with the needs it meets, its goals, context, vision and pedagogical foundation. The first question is answered by the
CDIO Syllabus and the process for reaching stakeholder consensus on the level of proficiency that students should attain in
a given program. The second question is addressed through a best practice framework, which discusses curriculum design, design-implement
experiences, teaching and learning, student assessment, program evaluation and faculty competence. Examples are provided of
the implementation of best practices within the CDIO program in Aeronautics and Astronautics at the Massachusetts Institute
of Technology (MIT).

Unbonded beams supported by a foundation are studied. The foundation is assumed that tensile stresses cannot be transmitted across the interface between beams and their supporting subgrade. The subgrade is characterized by a two-parameter model proposed by Vlasov and Leont'ev, Pasternak and Filonenko-Borodich. Thus the shear strength of the foundation material is taken into account. With a suitable choice of parameters, analytical solutions are obtained and compared to experimental results reported by Durelli et al. The effects of the “lift up” of the beam and a discussion of the foundation parameters are also presented. 相似文献

In this article, we elaborate on the meaning of quality in digital libraries (DLs) by proposing a model that is deeply grounded in a formal framework for digital libraries: 5S (Streams, Structures, Spaces, Scenarios, and Societies). For each major DL concept in the framework we formally define a number of dimensions of quality and propose a set of numerical indicators for those quality dimensions. In particular, we consider key concepts of a minimal DL: catalog, collection, digital object, metadata specification, repository, and services. Regarding quality dimensions, we consider: accessibility, accuracy, completeness, composability, conformance, consistency, effectiveness, efficiency, extensibility, pertinence, preservability, relevance, reliability, reusability, significance, similarity, and timeliness. Regarding measurement, we consider characteristics like: response time (with regard to efficiency), cost of migration (with respect to preservability), and number of service failures (to assess reliability). For some key DL concepts, the (quality dimension, numerical indicator) pairs are illustrated through their application to a number of “real-world” digital libraries. We also discuss connections between the proposed dimensions of DL quality and an expanded version of a workshop’s consensus view of the life cycle of information in digital libraries. Such connections can be used to determine when and where quality issues can be measured, assessed, and improved – as well as how possible quality problems can be prevented, detected, and eliminated. 相似文献

We examined 79 Japanese MNCs’ R&D subsidiaries in the US from the knowledge-based view. We found: (1) subsidiaries’ R&D strategies generally encouraged knowledge flows; (2) subsidiaries’ R&D alliances promoted knowledge flows; (3) R&D subsidiaries with process-oriented incentives promoted vertical knowledge flows; (3) autonomous R&D subsidiaries promoted knowledge flows from the local environments to the subsidiary; (4) R&D subsidiaries with a high level of knowledge flows accumulated a high level of knowledge; and (5) R&D subsidiaries with a high level of accumulated knowledge achieved high overall performance. Our interviews with 30 R&D subsidiaries and 10 parent companies supplement these findings. 相似文献

Past research has drawn attention to the unique challenges for students of color attending predominantly white colleges and universities, yet few have focused on the classroom as a micro-context in which race-related discussions often occur. Using a focus group methodology, 22 African American undergraduate students from a variety of academic programs shared their past experiences with classroom discussions about race. Thematic analyses revealed that African American students’ cognitive and emotional responses to race-focused discussions in the classroom were uniquely shaped by the broader context of attending a predominantly White university situated in a Midwestern region of the United States. Students’ responses gave insights into the strategies that minority students use to navigate race-focused discussions in class and the impact that those strategies have on their class participation. The implications of our results for students and faculty, particularly those situated on predominantly White campuses, are discussed. 相似文献

The aims of our current study were to (1) explore how community college science and mathematics majors made meaning of their experiences with mentor teachers as part of an early field experience and (2) understand the ways students’ experiences with mentors influenced their interest in teaching. Using interviews and written reflection activities, a qualitative phenomenological approach was used to understand and describe the meaning of the lived mentoring experiences of 17 community college science and mathematics majors. Five themes were identified to describe community college students’ experiences with mentor teachers in elementary, middle and high schools in a high-needs school district: (a) role modeling, (b) mutual respect and honesty, (c) responsiveness and guidance, (d) approachability and relatedness, and (e) broadening and shifting perspectives. Findings point to the potential of early relationships with mentor teachers as a means to shape community college students’ interest in teaching science or mathematics. 相似文献
