Using Exploratory Bifactor Analysis to Understand the Latent Structure of Multidimensional Psychological Measures: An Example Featuring the WISC-V

Exploratory bifactor analysis (EBFA) represents a methodological advancement for implementing a bifactor model in exploratory factor analysis (EFA). However, little is known about how to properly employ the procedure. The current rotation criteria available for EBFA make it more likely to “get stuck” in local minima, contributing to possible group factor collapse, than more traditional EFA rotations. Thus, getting a proper solution is a more complex and involved process than typical EFA and may require a sensitivity analysis. This article examines EBFA through a sensitivity analysis and subsequent simulation of parameters thought to contribute to group factor collapse. Results support the use of sensitivity analysis, as the problematic variable was shown to greatly increase the likelihood of factor collapse. The hypothesis that estimation start values contribute to factor collapse was not supported. Accompanying R syntax for all analyses are provided to facilitate reproducibility.  相似文献

Rhetoric and practice in pre-service teacher education: the case of Teach For America     

Jack Schneider 《教育政策杂志》2014,29(4):425-442

Teach For America (TFA), an organization that places college graduates in urban and rural classrooms for two-year terms of service, is lauded by reformers who see its five-week summer training institute as evidence that teachers have little to learn before entering classrooms. Yet, while boosters see TFA as a radical alternative to traditional teacher education, a look at the evolution of their increasingly robust summer training model hardly affirms that perception. In fact, much of what is done in the summer institute parallels the work of traditional teacher education programs in the USA – a surprising state of affairs given the rhetoric of so many TFA supporters. This project traces the evolution of TFA’s summer training institute across two decades, highlighting the growing divide between TFA’s outward-facing image and its actual work. Framing TFA’s summer institute as a case study for examining the relationship between rhetoric and practice in education, the article raises broader questions about how the policy-making context affects the construction and perception of reality.  相似文献   

Fostering self-monitoring of university students by means of a standardized learning journal—a longitudinal study with process analyses     

Sabine Fabriz  Charlotte Dignath-van Ewijk  Gregory Poarch  Gerhard Büttner 《European Journal of Psychology of Education - EJPE》2014,29(2):239-255

The self-regulation of learning behavior is an important key competence for university students. In this presented study, we aimed at fostering students’ self-regulation of learning by means of a standardized learning journal. In two of four courses that were included in the study, students had to keep a structured learning diary and/or received further intervention on self-regulated learning through a weekly course. Students who received these interventions were compared to students who received no treatment whatsoever in their self-regulation and learning achievement. The study reports pre–post measures as well as process analyses. Results revealed that keeping a structured learning diary without any further intervention did not improve students’ self-regulation. Those students who only kept learning diaries even showed a decrease in their motivation. Students who kept the learning diary and at the same time received further information on self-regulation showed increases in their strategy use and their self-efficacy. However, no improvements were found for students’ academic performance. It can be concluded that in order for students to profit in keeping a structured learning diary, they should be informed on the benefits of self-monitoring to increase their motivation.  相似文献   

Beyond hype and underestimation: identifying research challenges for the future of MOOCs     

Gerhard Fischer 《Distance Education》2014,35(2):149-158

Massive open online courses (MOOCs) have generated enthusiasm, excitement, and hype worldwide and recently increasing skepticism. They are being broadly discussed in the major news media (and to a smaller extent in academic circles). Rapidly increasing numbers of MOOC providers, MOOC courses and articles, discussion groups, and blogs discussing MOOCs are indicators of the involvement of many stakeholders. Most of these analyses and developments are based on economic perspectives (such as scalability, productivity, and being free) and technology perspectives (including platforms supporting large number of students in online environments, enrichment components such as forums, peer-to-peer learning support, and automatic grading). Few contributions analyze MOOCs from a learning science perspective and put them into a larger context with other approaches to learning and education. This commentary explores challenges derived from the perspective to conceptualize MOOCs as being one component in a rich landscape of learning.  相似文献   

Effective Engagement Strategies for Non-Tenure-Track Faculty in Precollege Mathematics Reform in Community Colleges     

Gabrielle Gerhard 《Community College Journal of Research & Practice》2014,38(2-3):208-217

The success of efforts to improve student outcomes in precollege mathematics at community colleges hinges on engaging and supporting non-tenure-track faculty [NTTF], who comprise a significant proportion of precollege instructional staff. Although research suggests weak departmental support and barriers and constraints to NTTF engagement, no studies have focused specifically on NTTF in the context of precollege mathematics reform in community colleges. This qualitative case study fills a gap in our understanding through interviews with seven tenure-track faculty [TTF] and 11 NTTF from three departments participating in the Washington State Rethinking Pre-College Mathematics grant. The case study examines the nature and effectiveness of strategies and incentives developed by TTF to engage their NTTF peers in department-led reform of precollege mathematics. Each department was successful in securing NTTF engagement across a broad spectrum, using strategies that included offering perquisites, professional development, and targeted instructional support. The NTTF detailed some changes in their practice, such as diversifying classroom instruction and approaches to assessment. Strategies that successfully initiated engagement (e.g., compensation) differed from those that sustained engagement, with the latter leveraging NTTF interest in growing professionally in order to improve student outcomes and build professional relationships with peers. Findings inform the delivery of NTTF professional development by suggesting that education and training expand beyond the delivery of new content to include relationship building with other faculty. The study's findings also consider NTTF professional development to be a shared responsibility among departments, colleges, systems, and NTTF.  相似文献   

The other partition: religious and secular education in British Palestine     

Suzanne Schneider 《Critical Studies in Education》2014,55(1):32-43

The recent critical turn toward post-secularism, particularly on behalf of theorists working from the perspective of Christian societies, has highlighted the difficulty of approaching the history of the Middle East through the binary of religion and secularism. This article argues that such terms are of little explanatory value in and of themselves, but rather must themselves be explained as unique historical objects. Through an analysis of the Arab public school system created by the government of Mandatory Palestine, this study demonstrates how the transformation of Islamic education occurred within a matrix of colonial domination that promoted its unique understanding of religion as a universal standard. By tracing the emergence of ‘religion’ as a distinct category of knowledge and human experience in modern Palestine, this article draws attention to the factors that distinguish the development of colonial secularism from phenomena observed in the Euro-American context.  相似文献   

未来气候变化对鄱阳湖区土地利用变化的影响评估   总被引：2，自引：0，他引：2  

闫丹  UweA.Schneider  ErwinSchmi  黄河清  潘理虎  OliverDilly 《资源科学》2013,35(11):2255-2265

为了评估未来气候变化可能对鄱阳湖区土地利用变化产生的影响,本文根据IPCC的建议,利用新近建立的基于主体的土地利用变化模拟模型,详细分析了4种气候变化情景下鄱阳湖区1985-2035年的土地利用变化过程。这4种气候变化情景分别为A1B(经济高速增长模式)、A2(区域经济多样化增长模式)、B1(引进更多清洁能源的经济增长模式)和情景4(无气候变化模式)。在这些气候变化情景中,由于耕地的农业生产潜力差异显著,农户主体的收入和他们对土地利用方式的决策也发生了相应的改变。通过对这一过程的模拟和结果分析,发现气候变化可能有利于鄱阳湖区土地利用变化向着环境友好的方向自我调整。与A1B和A2两种气候变化情景相比,B1情景对土地利用变化的影响更具环境友好性。  相似文献   

Thinking Like a Scientist: Using Vee-Maps to Understand Process and Concepts in Science     

Christine M. Knaggs  Rebecca M. Schneider 《Research in Science Education》2012,42(4):609-632

It is considered important for students to participate in scientific practices to develop a deeper understanding of scientific ideas. Supporting students, however, in knowing and understanding the natural world in connection with generating and evaluating scientific evidence and explanations is not easy. In addition, writing in science can help students to understand such connections as they communicate what they know and how they know it. Although tools such as vee-maps can scaffold students?? efforts to design investigations, we know less about how these tools support students in connecting scientific ideas with the evidence they are generating, how these connections develop over time, or how writing can be used to encourage such connections. In this study, we explored students?? developing ability to reason scientifically by examining the relationship between students?? understanding of scientific phenomena and their understanding of how to generate and evaluate evidence for their ideas in writing. Three high school classes completed three investigations. One class used vee-mapping each time, one used vee-mapping once, and one did not use vee-mapping. Students?? maps and written reports were rated for understanding of relevant science procedural and conceptual ideas. Comparisons between groups and over time indicate a positive relationship between improved procedural and conceptual understanding. Findings also indicate that improved procedural understanding preceded improved conceptual understanding, and thus, multiple experiences were needed for students to connect evidence and explanation for science phenomena.  相似文献
