A case for collaboratives: Turning around the Bronx public schools     

Stephen Franse  Adrienne Siegel 《The Urban Review》1987,19(2):129-135

This article chronicles pace-setting collaborative educational programs which are succeeding in turning around Bronx public schools. It focuses on the results achieved when corporations, universities, cultural institutions, and health-care facilities become partners with the public schools to share their expertise, sophisticated technology, and superior financial resources with the city's children. The marshalling of new resources from outside the school establishment in support of a number of initiatives has set public education in the Bronx on a new course. The transformation of many troubled neighborhood high schools into theme schools which feature a particular career preparation has already brought dramatic changes in the borough's dropout rate and raised the aspirations of large numbers of students.  相似文献   

Validity of self-reported reading disability by parents of reading-disabled and control children     

Sadie N. Decker  George P. Vogler  J. C. Defries 《Reading and writing》1989,1(4):327-331

Composite reading scores obtained from parents of 125 reading-disabled children and 125 matched control children who participated in the Colorado Family Reading Study were used to test the validity of self-reported reading problems. Parents who reported that they encountered serious difficulty learning to read had significantly lower reading scores than did those who reported no positive history of reading problems. Moreover, this difference was larger for parents of reading-disabled children than for those of controls. Thus, parental self-reports provide a valid index of reading problems.  相似文献   

Subtypes, severity, and structural stability of peer victimization: what does latent class analysis say?   总被引：2，自引：1，他引：1  

Nylund K  Bellmore A  Nishina A  Graham S 《Child development》2007,78(6):1706-1722

This study uses latent class analysis (LCA) to empirically identify victimization groups during middle school. Approximately 2,000 urban, public middle school students (mean age in sixth grade = 11.57) reported on their peer victimization during the Fall and Spring semesters of their sixth, seventh, and eighth grades. Independent LCA analyses at each semester yielded 3 victim classes based on victimization degree rather than type (e.g., physical vs. relational). The most victimized class always represented the smallest proportion of the sample, decreasing from 20% in sixth grade to 6% by the end of eighth grade. This victimized class also always reported feeling less safe at school concurrently and more depressed than others 1 semester later, illustrating the validity of the LCA approach.  相似文献   

Validation of an integrated experimental set-up for kinetic and kinematic three-dimensional analyses in a training environment     

Boisnoir A  Decker L  Reine B  Natta F 《Sports biomechanics / International Society of Biomechanics in Sports》2007,6(2):215-223

Biomechanical analyses using synchronized tools [electromyography (EMG), motion capture, force sensors, force platform, and digital camera] are classically performed in a laboratory environment that could influence the performance. We present a system for studying the running sprint start that synchronizes motion capture, EMG, and ground reaction force data. To maximize motion capture (Vicon 612 with six cameras), a special dim environment was created in the stadium. "Classical" tools were combined with "purpose-built" tools intended to analyse the different aspects of movement. For example, a synchronization system was built to create a common time-base for all data recordings and a portable EMG system was synchronized by a cable that was "disconnected" by the athlete's movement out of the blocks. This disconnection represented an independent event recorded by different tools. A "gap" was measured for some sprint start events between kinetic and kinematic (motion capture) data. Calibration results, measurements of time "gap", and duration of the independent event were used to validate the accuracy of motion capture and the synchronization system. The results validate the entire experimental set-up and suggest adjustment values for motion capture data. This environment can be used to study other movements and can easily be applied to several sports.  相似文献   

SPECIFIC COGNITIVE PREDICTORS OF EARLY MATH PROBLEM SOLVING     

Scott L. Decker  Alycia M. Roberts 《Psychology in the schools》2015,52(5):477-488

Development of early math skill depends on a prerequisite level of cognitive development. Identification of specific cognitive skills that are important for math development may not only inform instructional approaches but also inform assessment approaches to identifying children with specific learning problems in math. This study investigated the specific cognitive correlates of math problem solving across early grade levels (1–4) while controlling for basic calculation skills. As expected, basic calculation skill was a significant predictor of math problem solving across the entire sample. However, the addition of cognitive measures almost doubled the variance explained (R² = .61). Additionally, only select cognitive variables contributed to the prediction of math problem solving, and these variables change in importance as children develop higher‐level math skills. Results are discussed within a developmental model, which emphasizes the increasing importance of abstract code representations required in higher levels of math performance.  相似文献   

Solution pH change in non-uniform alternating current electric fields at frequencies above the electrode charging frequency     

Ran An  Katherine Massa  David O. Wipf  Adrienne R. Minerick 《Biomicrofluidics》2014,8(6)

AC Faradaic reactions have been reported as a mechanism inducing non-ideal phenomena such as flow reversal and cell deformation in electrokinetic microfluidic systems. Prior published work described experiments in parallel electrode arrays below the electrode charging frequency (f_c), the frequency for electrical double layer charging at the electrode. However, 2D spatially non-uniform AC electric fields are required for applications such as in plane AC electroosmosis, AC electrothermal pumps, and dielectrophoresis. Many microscale experimental applications utilize AC frequencies around or above f_c. In this work, a pH sensitive fluorescein sodium salt dye was used to detect [H⁺] as an indicator of Faradaic reactions in aqueous solutions within non-uniform AC electric fields. Comparison experiments with (a) parallel (2D uniform fields) electrodes and (b) organic media were employed to deduce the electrode charging mechanism at 5 kHz (1.5f_c). Time dependency analysis illustrated that Faradaic reactions exist above the theoretically predicted electrode charging frequency. Spatial analysis showed [H⁺] varied spatially due to electric field non-uniformities and local pH changed at length scales greater than 50 μm away from the electrode surface. Thus, non-uniform AC fields yielded spatially varied pH gradients as a direct consequence of ion path length differences while uniform fields did not yield pH gradients; the latter is consistent with prior published data. Frequency dependence was examined from 5 kHz to 12 kHz at 5.5 V_pp potential, and voltage dependency was explored from 3.5 to 7.5 V_pp at 5 kHz. Results suggest that Faradaic reactions can still proceed within electrochemical systems in the absence of well-established electrical double layers. This work also illustrates that in microfluidic systems, spatial medium variations must be considered as a function of experiment time, initial medium conditions, electric signal potential, frequency, and spatial position.  相似文献

Reciprocal learning: One teacher’s narrative     

Adrienne Rigler 《Frontiers of Education in China》2017,12(2):219-232

This paper is a personal narrative from the perspective of one teacher in Toronto who participated in the Canada–China Reciprocal Learning in Teacher Education and School Education Partnership Grant Project. I took part in a Sister School partnership between 2013 and 2017. Over the four years, I came to understand relationships in an international professional learning community. Participating in the project gave me the benefit of seeing my practice through an international lens. For my students, it offered a global citizenship experience. Although there are numerous professional development opportunities in Toronto, this partnership extends beyond a lunch and learn, or a full day professional learning. The commitment to my partners has fueled my desire to incorporate new teaching ideas and has required ongoing reflection on my own teaching practice. In this article, I will explain some of the challenges, stages of development, reciprocal learning, and implications for future international professional learning communities.  相似文献   

Graduate identity and employability     

Geoffrey William Hinchliffe  Adrienne Jolly 《British Educational Research Journal》2011,37(4):563-584

This paper develops the concept of graduate identity as a way of deepening the understanding of graduate employability. It does this through presenting research in which over 100 employers in East Anglia were asked to record their perceptions of graduates in respect of their employability. The findings suggest a composite and complex graduate identity, depending on employer size and sector. There is no one fixed identity for graduates. Nevertheless, certain themes emerged that seriously put into question the traditional model of graduate employability comprising skills, competencies and attributes. What emerges is a four‐stranded concept of identity that comprises value, intellect, social engagement and performance. Thus, when assessing the potential of graduates, performance is not the only criteria that employers take into account. Moreover, the four elements of identity are by no means independent of each other but are expected to interpenetrate producing a composite identity, with different employers emphasising different facets of this identity.
