Curriculum innovation within an evaluative state: issues of risk and regulation     

David Halpin  Marny Dickson  Sally Power  Geoff Whitty  Sharon Gewirtz 《Curriculum Journal》2013,24(3):197-206

The English EAZ experience illustrates the difficulties of developing an innovative, responsive and inclusive curriculum within an evaluative state characterized by high stakes testing. Consequently, while government exhortations to ‘raise standards’, ‘innovate’ and ‘promote social inclusion’ clearly serve an important rhetorical function, they may underestimate the challenges involved and overestimate the capacity of schools within disadvantaged areas to ‘make a difference’.  相似文献

Examining the Enactment of Web GIS on Students' Geospatial Thinking and Reasoning and Tectonics Understandings     

Alec M. Bodzin  Qiong Fu  Denise Bressler  Farah L. Vallera 《学校用计算机》2015,32(1):63-81

Geospatially enabled learning technologies may enhance Earth science learning by placing emphasis on geographic space, visualization, scale, representation, and geospatial thinking and reasoning (GTR) skills. This study examined if and how a series of Web geographic information system investigations that the researchers developed improved urban middle-school learners’ GTR skills and their understanding of tectonics concepts. Paired-sample t tests for analyses of tectonics content knowledge and GTR achievement measures revealed statistically significant gains from pretest to posttest (p <.001) with large effect sizes. The findings provide support that GTR related to tectonics can be learned with appropriately designed learning activities using Web-based geographic information systems.  相似文献   

Beginning teachers as enquirers: m-level work in initial teacher education     

Beth Dickson 《欧洲师范教育杂志》2011,34(3):259-276

In order to deliver life-long learning for teachers, practitioner-based enquiry learning is being promoted by teacher education institutions on the basis that this form of learning gives teachers the ability to understand factors affecting learning within their own classrooms by systematic investigations of issues and the construction of an evidence-base on which decisions which improve learning can be taken. In turn this enhances teacher professionalism. This article presents a study of how practitioner-based enquiry was embedded in an initial teacher education programme; the reasons for this; and the purposes of the strategy, which raised the one-year postgraduate qualification to masters-level. It looks at the reasons for the change; the nature of the change, which included educating teachers intending to teach in primary schools together with those intending to teach in secondary; the introduction of practitioner-based enquiry; some early student reaction; and the structural, cultural and learning issues which have emerged.  相似文献   

Economic returns to education: What We Know, What We Don’t Know, and Where We Are Going—Some brief pointers     

Matt Dickson  Colm Harmon 《Economics of Education Review》2011,30(6):1118-1122

The estimation of the economic return to education has perhaps been one of the predominant areas of analysis in applied economics for over 50 years. In this short note we consider some of the recent directions taken by the literature, and also some of the blockages faced by both science and policymakers in pushing forward some key issues. This serves by way of introduction to a set of papers for a special issue of the Economics of Education Review.  相似文献   

The Effectiveness of the Geospatial Curriculum Approach on Urban Middle-Level Students’ Climate Change Understandings   总被引：2，自引：1，他引：1

Climate change science is a challenging topic for student learning. This quantitative study examined the effectiveness of a geospatial curriculum approach to promote climate change science understandings in an urban school district with eighth-grade students and investigated whether teacher- and student-level factors accounted for students’ climate change knowledge achievement. The participants included 12 science teachers and 956 eighth-grade students. Data included a pre- and posttest climate change assessment measures for both teachers and students and a teacher measure of Geospatial Science-Technological Pedagogical Content Knowledge. Paired-sample t tests revealed statistically significant gains from pretest to posttest on their climate change knowledge (p < .001; effect sizes being large on multiple-choice items and medium on the open-ended response assessment). Both ordinary least squares (OLS) multiple regression and 2-level hierarchical linear modeling found that students’ initial climate change knowledge and gender were significant predictors for students’ posttest scores, p < .05. Students’ pretest scores were the strongest significant predictor of the posttest scores, p < .001. Neither the teachers’ climate change knowledge nor their Geospatial Science-Technological Pedagogical Content Knowledge had significant association with the students’ posttest scores. Teaching years was a significant predictor for students’ posttest scores in OLS regression (p < .001). The findings provide support that a geospatial curriculum approach is an effective science curriculum approach for learners in urban middle-level education.  相似文献

Analysis of a laminar-flow diffusional mixer for directed self-assembly of liposomes     

Matthew J. Kennedy  Harold D. Ladouceur  Tiffany Moeller  Dickson Kirui  Carl A. Batt 《Biomicrofluidics》2012,6(4)

The present work describes the operation and simulation of a microfluidic laminar-flow mixer. Diffusive mixing takes place between a core solution containing lipids in ethanol and a sheath solution containing aqueous buffer, leading to self assembly of liposomes. Present device architecture hydrodynamically focuses the lipid solution into a cylindrical core positioned at the center of a microfluidic channel of 125 × 125-μm² cross-section. Use of the device produces liposomes in the size range of 100–300 nm, with larger liposomes forming at greater ionic strength in the sheath solution and at lower lipid concentration in the core solution. Finite element simulations compute the concentration distributions of solutes at axial distances of greater than 100 channel widths. These simulations reduce computation time and enable computation at long axial distances by utilizing long hexahedral elements in the axial flow region and fine tetrahedral elements in the hydrodynamic focusing region. Present meshing technique is generally useful for simulation of long microfluidic channels and is fully implementable using comsol Multiphysics. Confocal microscopy provides experimental validation of the simulations using fluorescent solutions containing fluorescein or enhanced green fluorescent protein.  相似文献
