The issue of implementing large-scale reforms has played an important role both in the past as well as in current debates on structural changes and quality measures in education. When putting reforms into practice, individual schools and their leaders, who take a key role in reform processes, are focused. In the context of a comprehensive school reform in Berlin, this contribution presents an implementation of the Stages of Concern Questionnaire (SoCQ, Hall and Hord 2011), which intends to assess the degree of participants’ engagement with innovations in a phased respectively stepwise approach. Recently, the SoCQ questionnaire has been used to build different profiles or types of engagement in reform. Based on N?=?196 school leaders, latent profile analyses thus served to identify five types of profiles. Altogether, they indicate that the majority of school leaders are ready to implement the reform and contribute to its optimization. A rather small group remained skeptical with regard to the school reform. With respect to individual leadership characteristics, differences in profile composition could be found for gender, school type, and professional experience.  相似文献   

Molecular thermodynamics for cell biology as taught with boxes     

Mayorga LS  López MJ  Becker WM 《CBE life sciences education》2012,11(1):31-38

Thermodynamic principles are basic to an understanding of the complex fluxes of energy and information required to keep cells alive. These microscopic machines are nonequilibrium systems at the micron scale that are maintained in pseudo-steady-state conditions by very sophisticated processes. Therefore, several nonstandard concepts need to be taught to rationalize why these very ordered systems proliferate actively all over our planet in seeming contradiction to the second law of thermodynamics. We propose a model consisting of boxes with different shapes that contain small balls that are in constant motion due to a stream of air blowing from below. This is a simple macroscopic system that can be easily visualized by students and that can be understood as mimicking the behavior of a set of molecules exchanging energy. With such boxes, the basic concepts of entropy, enthalpy, and free energy can be taught while reinforcing a molecular understanding of the concepts and stressing the stochastic nature of the thermodynamic laws. In addition, time-related concepts, such as reaction rates and activation energy, can be readily visualized. Moreover, the boxes provide an intuitive way to introduce the role in cellular organization of "information" and Maxwell's demons operating under nonequilibrium conditions.  相似文献

The Critical Thinking Analytic Rubric (CTAR): Investigating intra-rater and inter-rater reliability of a scoring mechanism for critical thinking performance assessments     

Emily Saxton  Secret Belanger  William Becker 《Assessing Writing》2012,17(4):251-270

The purpose of this study was to investigate the intra-rater and inter-rater reliability of the Critical Thinking Analytic Rubric (CTAR). The CTAR is composed of 6 rubric categories: interpretation, analysis, evaluation, inference, explanation, and disposition. To investigate inter-rater reliability, two trained raters scored four sets of performance-based student work samples derived from a pilot study and subsequent larger study. The two raters also blindly scored a subset of student work samples a second time to investigate intra-rater reliability. Participants in this study were high school seniors enrolled in a college preparation course. Both raters showed acceptable levels of intra-rater reliability (α ≥ 0.70) in five of the six rubric categories. One rater showed poor consistency (α = 0.56) for the analysis category of the rubric, while the other rater showed excellent consistency (α = 0.91) for the same category suggesting the need for further training of the former rater. The results of the inter-rater reliability investigation demonstrate acceptable levels of consistency (α ≥ 0.70) in all rubric categories. This investigation demonstrated that the CTAR can be used by raters to score student work samples in a consistent manner.  相似文献   

A Community of Practice Model for Introducing Mobile Tablets to University Faculty     

Michelle Drouin  Lesa Rae Vartanian  Samantha Birk 《Innovative Higher Education》2014,39(3):231-245

We examined the effectiveness of a community of practice (CoP) model for introducing tablets to 139 faculty members at a higher education institution. Using a CoP within a systems model, we used large- and small-group mentorship to foster collaboration among faculty members. Most faculty members agreed that the project was well organized and activities were useful. In terms of measurable outcomes, many participants had developed plans for or completed scholarly activities related to tablets. Our findings support the use of CoP models to integrate technology within higher education. Additionally, they support such integrations as proof of concept for large, whole-campus technology integrations.  相似文献   

The NYU Survey Service: Promoting Value in Undergraduate Education     

Jason B. Phillips  Samantha A. Guss  David M. McGarry 《College & Undergraduate Libraries》2013,20(2-3):183-199

New York University's (NYU) Data Service Studio has recently launched the NYU Survey Service, whose ultimate aim is to support the development and administration of surveys of all types. For the Web-based component, the service utilizes a product called Qualtrics, which allows university affiliates to develop and administer Web-based surveys. This article describes the process by which NYU came to offer the service during a time when concerns abound about the ability of libraries to support and expand offerings while still meeting institutional imperatives such as robust data services. While many considerations went into the evaluation and ultimate conclusion to pilot the service, this article considers those most related to library collaborations, undergraduate instruction, data and information literacy, learning and research, and application administration and support.  相似文献   

Comedy Types and Political Campaigns: The Differential Influence of Other-Directed Hostile Humor and Self-Ridicule on Candidate Evaluations     

Amy B. Becker 《Mass Communication and Society》2013,16(6):791-812

The current study assesses the effect of exposure to diverse comedy types, measuring the differential impact of other-directed hostile humor and self-ridicule on feelings toward John McCain. Specifically, the analyses use experimental data collected in 2009 to compare the differential impact of viewing a video clip of John McCain's playful self-satire on Saturday Night Live with the effects of exposure to the more aggressive, judgmental, other-directed hostile humor of Stephen Colbert. The results suggest that viewers cool toward McCain after exposure to Stephen Colbert's other-directed hostile humor. Additional analyses show that the effect of exposure to varied types of political humor is direct and relatively impervious to moderation by political partisanship. Implications of the findings and their ability to help researchers understand the differential influence of varied comedy message types on political evaluations and attitudes is discussed.  相似文献   

An Examination of Coursera as an Information Environment: Does Coursera Fulfill its Mission to Provide Open Education to All?     

Samantha Audsley  Kalyani Fernando  Brittany Robinson  Katie Varney 《期刊图书馆员》2013,64(2):136-166

In terms of international education, the concept of online education seems to be a growing trend. Edxonline.org, Minervaproject.com, and Udacity.com are all new massive online open courses (MOOCs)—education websites similar to Coursera offering students the ability to receive the best education from elite universities entirely online. The most tantalizing promise of a company like Coursera is the role it might play in improving education for the world's have-nots: high school dropouts, the global poor, and those less able to self-teach.  相似文献
