The role of mediating organizations for school reform: independent agents or district dependents?

This paper examines the role of mediating organizations in helping schools engage in whole school change as part of a school district's reform agenda. Specifically, it examines the Learning Community Program in Los Angeles, a programme designed by an external school reform organization, to assist schools in planning and implementing LEARN (Los Angeles Educational Alliance for Restructuring Now). The programme's success is shaped by the district and school contexts in which it operates. As mediating agent, the Learning Community Program must balance the challenges facing the schools ‐‐ particularly their readiness to engage in reform ‐‐ with the demands of the district for scale, accountability and resources. As it does so, it faces the challenges of maintaining program flexibility, building sustainable changes, and preserving its organizational independence. These pressures generate three central dilemmas and threaten to undermine the success of the district's reform and the Learning Community Program ‐‐ scale versus sustainability, district mandates versus site autonomy, and organizational independence versus survival. It concludes that mediating agencies can be constrained by their dependence on policymakers for critical resources.     

The Rural School Leadership Dilemma

The idea that rural schools and communities, indeed, even rural people, are somehow substandard or second-class has deep historical roots. The goal of this essay is to reveal that history so as to render stereotypical conceptions all things rural less powerful and more easily dismissed by rural school professionals. Consequently the focus is on one dilemma every rural school leader faces: when to speak up in the face of rural denigration.     

The predicted risk of head injury from fall-related impacts on to third-generation artificial turf and grass soccer surfaces: A comparative biomechanical analysis

The risk of soccer players sustaining mild traumatic brain injury (MTBI) following head impact with a playing surface is unclear. This study investigates MTBI by performing headform impact tests from varying heights onto a range of third-generation artificial turf surfaces. Each turf was prepared as per manufacturers specifications within a laboratory, before being tested immediately following installation and then again after a bedding-in period. Each turf was tested dry and when wetted to saturation. Data from the laboratory tests were compared to an in situ third-generation surface and a professional grass surface. The surface performance threshold was set at a head impact criterion (HIC) = 400, which equates to a 10% risk of the head impact causing MTBI. All six third-generation surfaces had a >10% risk of MTBI from a fall >0.77 m; the inferior surfaces required a fall from just 0.46 m to have a 10% MTBI risk. Wetting the artificial turf did not produce a statistically significant improvement (P > 0.01). The in situ third-generation playing surface produced HIC values within the range of bedded-in experimental values. However, the natural turf pitch was the superior performer – necessitating fall heights exceeding those achievable during games to achieve HIC = 400.     

Using observational feedback to promote academic development

The purpose of this paper is to illustrate how professional consultants can use observational feedback to improve instructional effectiveness and to strengthen the academic identity of university teachers. To this end, a three-step approach is presented together with guidelines for giving feedback. A case example, based on the author's own practice, is used to highlight the complexities involved and to draw attention to the need for professionals to use their expert-power base judiciously.     

Are Virtual Labs as Effective as Hands-on Labs for Undergraduate Physics? A Comparative Study at Two Major Universities

Most physics professors would agree that the lab experiences students have in introductory physics are central to the learning of the concepts in the course. It is also true that these physics labs require time and money for upkeep, not to mention the hours spent setting up and taking down labs. Virtual physics lab experiences can provide an alternative or supplement to these traditional hands-on labs. However, physics professors may be very hesitant to give up the hands-on labs, which have been such a central part of their courses, for a more cost and time-saving virtual alternative. Thus, it is important to investigate how the learning from these virtual experiences compares to that acquired through a hands-on experience. This study evaluated a comprehensive set of virtual labs for introductory level college physics courses and compared them to a hands-on physics lab experience. Each of the virtual labs contains everything a student needs to conduct a physics laboratory experiment, including: objectives, background theory, 3D simulation, brief video, data collection tools, pre- and postlab questions, and postlab quiz. This research was conducted with 224 students from two large universities and investigated the learning that occurred with students using the virtual labs either in a lab setting or as a supplement to hands-on labs versus a control group of students using the traditional hands-on labs only. Findings from both university settings showed the virtual labs to be as effective as the traditional hands-on physics labs.

Relational and Overt Aggression in Middle Childhood: Early Child and Family Risk Factors

This study investigated early child and family risk factors for relational and overt aggression in 207 children followed since birth. Risk factors were assessed during infancy and preschool, and aggression in Grades 1, 3, and 5. Independent risk factors for Aggression Severity (total of relational and overt aggression) included lower language abilities, lower levels of temperamental withdrawal/inhibition, and greater exposure to family environments characterized by maternal negativity toward the child, family negative expressiveness, and maternal depression. The major risk factor for Aggression Directionality (relative preponderance of relational versus overt aggression) was gender. Child temperament interacted with family risk factors in predicting Severity, and child gender moderated the associations of temperament and family risk factors in predicting both Severity and Directionality.
