ABSTRACT

The Great Khan's atlas contains also the maps of the promised lands visited in thought but not yet discovered or founded: New Atlantis, Utopia, the City of the Sun, Oceana, Tamoé, New Harmony, New Lanark, Icaria.

A Review of: “Organizing Schools for Improvement: Lessons from Chicago. Anthony S. Bryk,Penny Bender Sebring,Elaine Allensworth,Stuart Luppescu,and John Q. Easton.”

This article summarizes the results of a study of state and local practices related to the implementation of Title I of the Improving America's Schools Act (IASA; 1994). In translating policy to practice, state and local practitioners articulated how they approached the provisions of IASA: the expectation that all children will meet challenging state standards, flexibility with accountability, targeting funds, family and community partnerships, and support system roles and infrastructure. This snapshot of reform in progress shows that multiple chains of events at the national and state levels influenced the implementation of the law and that more time and support are needed to produce the impact intended in the Title I reauthorization.     

A novel μ-fluidic whole blood coagulation assay based on Rayleigh surface-acoustic waves as a point-of-care method to detect anticoagulants

A universal coagulation test that reliably detects prolonged coagulation time in patients, irrespective of the anticoagulant administered, has not been available to date. An easily miniaturised, novel μ-fluidic universal coagulation test employing surface acoustic waves (SAW) is presented here. SAW was employed to instantly mix and recalcify 6 μl citrated whole blood and image correlation analysis was used to quantify clot formation kinetics. The detection of clinically relevant anticoagulant dosing with old anticoagulants (unfractionated heparin, argatroban) and new anticoagulants (dabigatran, rivaroxaban) has been tested and compared to standard plasma coagulation assays. The applicability of this novel method has been confirmed in a small patient population. Coagulation was dose-proportionally prolonged with heparin, argatroban, dabigatran, and rivaroxaban, comparable to standard tests. Aspirin and clopidogrel did not interfere with the SAW-induced clotting time (SAW-CT), whereas the strong GPIIb/IIIa-inhibitor abciximab did interfere. Preliminary clinical data prove the suitability of the SAW-CT in patients being treated with warfarin, rivaroxaban, or dabigatran. The system principally allows assessment of whole blood coagulation in humans in a point-of-care setting. This method could be used in stroke units, emergency vehicles, general and intensive care wards, as well as for laboratory and home testing of coagulation.     

Faculty and Students Conceptions of Assessment in Higher Education

Assessment in higher education serves multiple purposes such as providing information about student learning, student progress, teaching quality, and program and institutional accountability. Yet, little is known about faculty and students’ attitudes regarding different aspects of assessment that have wide-ranging implications for policy and practice in tertiary institutions. To investigate these views, parallel surveys of conceptions of assessment were administered to faculty and undergraduate students across four tertiary institutions including universities, an indigenous tertiary institution, and an institute of technology. A mean and covariance structures approach was used to test for measurement invariance and latent means differences between faculty and students regarding their conceptions of assessment. Results revealed differences in the latent means across the two groups. Faculty were likely to view assessment as a trustworthy process aiding teaching and learning, whereas students viewed assessment as focussed primarily on accountability and perceived assessment as irrelevant or even ignored in the teaching and learning process. These findings highlight the importance of ensuring that assessment policy and practices are fit for purposes, and are being carried out with integrity in ways that are transparent to and understood by both staff and students. While these results show how staff and students view assessment practices, one should keep in mind that while the sample was large and did incorporate different types of tertiary institutions, the inclusion of a broader range of disciplines would make the conclusions more generalizable.     

Threshold capabilities: threshold concepts and knowledge capability linked through variation theory

The Threshold Capability Integrated Theoretical Framework (TCITF) is presented as a framework for the design of university curricula, aimed at developing graduates’ capability to deal with previously unseen situations in their professional, social, and personal lives. The TCITF is a new theoretical framework derived from, and heavily dependent upon, the ideas of the Threshold Concepts Framework (Meyer and Land 2003a; Land et al. 2006) and Capability Theory (Bowden and Marton 1998; Bowden et al. 2000; Bowden 2004). Capability theory is firmly based in phenomenography and variation theory, is concerned with the development of knowledge capability, but has had limited application in practice. The threshold concepts framework has enjoyed greater acceptance by a large range of academics in many fields. This acceptance has initially focussed on analytic studies of what constitutes a threshold concept—and the location and distribution of such concepts—in a given domain. In many instances subsequent attention has focussed on issues of pedagogy and assessment, including the design of curricula. We propose a merging of capability theory and the threshold concepts framework and argue that capability and variation theories provide the ideal mechanism for developing a strong pedagogical approach based on newly emerging knowledge of the critical features of threshold concepts within different domains.     

Students' Conceptions of Research. 2: An exploration of contrasting patterns of variation

This study explores variation in postgraduate students' and supervisors' conceptions of research. Based on earlier work, a Conceptions of Research Inventory (CoRI) was trialled on a mixed sample of postgraduate students and supervisors (n = 251). Exploratory factor analyses of resultant data yields a five‐dimensional empirical model, the composition of which is consistent with earlier work by the present authors. Four of these five dimensions distinguish between (variation in) conceptions of research such as “truth”, “problem‐solving”, “re‐search”, and “an insightful process”. The fifth dimension captures variation in terms of what are interpreted as “misconceptions”. The discrete conceptual dimensions suggested within the factor model are further explored via k‐means cluster analyses in terms of partitioning of the dataset, as limited by sample sizes, according to postgraduate status and supervisor designation. These analyses provide further insights into variation, across the various clusters in each case, as expressed in the profiles of cluster mean scores. Such differences as are evidenced highlight contrasting patterns of variation between, for example, experienced and novice researchers. There is also evidence of dissonance in some of the cluster solutions and it is further demonstrated via analysis of variance that dissonant cluster membership is associated with a generally lower level of self‐estimated performance. The implications of these findings are finally considered in relation to postgraduate training and supervision.     

Pupils Share in Control of Our Small Junior High School

A challenge for school libraries is the identification and management of electronic and paper resources that teachers and students need. Courtenay Middle School, on Vancouver Island, has begun to assemble collections of mediated online links, in addition to the traditional paper and video resources, and to ask fundamental questions related to ongoing collection development and the creation of communities of contributors.
