Meanings of success and successful leadership in Ontario,Canada, in neo-liberal times

The provincial government of Ontario, Canada, has committed itself to raising student achievement, closing achievement gaps, and increasing the public's confidence in public education. It has introduced many policies, including the Ontario Leadership Strategy (OLS), to support these goals. Our study examined how teachers, administrators, support staff, and parents in three elementary schools in Ontario understand and enact school success and successful school leadership within this (neo-liberal) context. Findings of a comparative analysis of Ontario policy texts and data from interviews with administrators, teachers, support staff, and parents in the schools demonstrate that the school-based participants defined success as academic learning, a positive school climate, and students' well-being. This definition differs from the definition prioritised by Ontario's government: high scores on standardised provincial and international tests. However, principals in the schools enacted leadership practices advocated by OLS to support locally defined notions of success.     

Educating the child care administrator

ABSTRACT

There is a strong national movement to improve the quality in child care programs nationwide and an important part of this movement includes professional preparation standards. Stakeholders in New York State (NYS) have developed the NYS Children’s Program Administrator Credential (CPAC), designed to meet the need for increased knowledge in child care administration. In response, Empire State College, part of the State University of New York (SUNY), developed four models to help practitioners meet the new requirement: study group, independent study, residency, and online. The purpose of this article is to examine the development of the credential, discuss the collaborative process involved in the development of the different modes of study, followed by a discussion of the strengths and challenges of each model.     

Development of the Statistical Reasoning in Biology Concept Inventory (SRBCI)

We followed established best practices in concept inventory design and developed a 12-item inventory to assess student ability in statistical reasoning in biology (Statistical Reasoning in Biology Concept Inventory [SRBCI]). It is important to assess student thinking in this conceptual area, because it is a fundamental requirement of being statistically literate and associated skills are needed in almost all walks of life. Despite this, previous work shows that non–expert-like thinking in statistical reasoning is common, even after instruction. As science educators, our goal should be to move students along a novice-to-expert spectrum, which could be achieved with growing experience in statistical reasoning. We used item response theory analyses (the one-parameter Rasch model and associated analyses) to assess responses gathered from biology students in two populations at a large research university in Canada in order to test SRBCI’s robustness and sensitivity in capturing useful data relating to the students’ conceptual ability in statistical reasoning. Our analyses indicated that SRBCI is a unidimensional construct, with items that vary widely in difficulty and provide useful information about such student ability. SRBCI should be useful as a diagnostic tool in a variety of biology settings and as a means of measuring the success of teaching interventions designed to improve statistical reasoning skills.     

A new approach to numerical integration by means of steady-state flux in a slab

The definite integral is generally interpreted geometrically as an “area”. An alternate interpretation as a steady-state “flux” through a unit slab is derived, which leads to a new method of numerical integration. The usual sum of a large number of approximate areas is replaced by the flux through a “single” increment.The method involves the solution of a system of linear finite difference equations. The coefficient matrix is tri-diagonal and is solved efficiently by the Thomas algorithm. During the iterative process the coefficients are determined by simple quadrature schemes applied to each increment.Error analysis revealed that an expression could be derived for the roundoff error associated with the final Thomas iteration. It is shown that the roundoff error is smallest when the matrix coefficients a_k\S>1. The method is shown to be superior to the classical methods due to its simplicity and tolerance for variable increment size. In addition, a new function is determined which is useful in diffusion studies. Numerical data are presented confirming these results.     

“Ebooks for the Classroom+” at University of South Florida Libraries: A Case Study of Database Management

The University of South Florida Libraries has supported a campus-wide “Textbook Affordability Project” initiative by creating and maintaining an ebooks database called “Ebooks for the Classroom+.” This database facilitates faculty members’ adoption of ebooks as textbooks through library acquisitions in the hope that students can achieve academic success without paying for expensive textbooks. It is built and run by the library, using data based on vendor-supplied information. This paper discusses the approaches, the challenges, and the future plans for building and updating the database.     

The diffusion of moisture in sorbent solids—I. Diffusion cell and pore diffusion

A complete theory of diffusion of absorbing gases in porous solids is developed. Both ordinary and thermal diffusion are considered. The thermodynamics of irreversible processes is used to derive the general flux equations.A new theoretical model of surface diffusion is presented. Moreover, the proper method of combining surface and gas-phase fluxes is established. The total flux in the pores is represented by a 5 parameter model, which includes the effects of (1) free (gaseous) diffusion, (2) Knudsen diffusion, and (3) surface diffusion.The design of a new diffusion cell is presented along with a stagewise method for analyzing results. The cell is unique in that specimens mounted in copper clad circuit board material permits nonisothermal as well as isothermal operation. Earlier designs were confined to isothermal operation due to mounting specimens in metallic materials such as brass and aluminum.     

Opportunity and Risk in Transnational Education—Issues in Planning for International Campus Development: An Australian Perspective

This article, that is based upon the experience of Monash University, identifies a range of opportunities and risks involved in transnational education and addresses a number of key planning issues in establishing an international campus. These include the guiding principles adopted by the university, country selection factors, market research, considerations in developing an appropriate delivery model, and the assurance of the academic quality and educational integrity of the programmes offered. The authors refer to literature in the field concerning corporate risk and identify factors relevant to the higher education sector. The article stresses the need for an appropriate integration of strategic vision, academic priorities, and business considerations to ensure that opportunities offered by transnational education are successfully realized.
