The Integrating and Segregating Effects of School Choice

We evaluate the integrating and segregating effects of three distinct school choice programs in San Diego. We go beyond the traditional question of racial integration and examine the integration of students by test scores, parental education levels, and language status. In addition to measuring the net integrative effects of school choice, we also examine the underlying motives behind student participation in school choice programs and the limiting influence of supply-side constraints. Two of the programs that we consider are rooted in 1970s integration-based reforms that provide public transportation for program participants. The third program is a state-mandated, open-enrollment program that requires participants to find their own transportation to and from their choice schools. We find that the two programs with underlying integrative objectives do indeed integrate the district, but the open-enrollment program segregates the district along most dimensions. Provision of busing and geographic preferences appear to be important factors in promoting integration.     

Impact attenuation provided by shin guards for field hockey

Low-energy impact testing of hockey shin guards was carried out using a drop test impact rig and a new physical setup protocol. Two brands of shin guards were impacted once (2.6 J, 3.3 J; without and with a sock), and impacted three times (3.3 J; with a sock). The peak force and impulse of a single impact increased with increasing impact energy (by approximately 30 and 7%, respectively) whilst repeated impacts increased the peak force and decreased the impulse (by approximately 70 and 3–9%, respectively, between one and three impact events). The presence of a sock attenuated impact force to a greater extent than the guards alone, at both impact energies. As a sock is usually worn over hockey shin guards, its presence contributes to enhanced protection to the lower limb.     

Delphi: a technique to harness expert opinion for critical decision‐making tasks in education

Expert rather than general or informal opinion is often sought in the development of educational policy. Decisions to be made regarding best practice, the most effective way to deliver services, issues dealing with the professional development of teachers and the distribution of limited educational resources are examples which require critical thinking and reasoning. Regardless of the nature of the task, complex decision‐making is rarely left to the remit of one person and there is usually an assumption made that ‘two heads are better than one’. The organisational requirements of collecting, analysing, refining and validating critical information can be a long, arduous and often tedious process‐‐a process which can often be overlooked, resulting in ill‐defined, poorly conceived, biased and invalid determinations. The conventional Delphi procedure offers decision‐makers a user‐friendly, rigorous and systematic strategy in the collection and dissemination of critical information. This paper reviews the substantive literature relating to the Delphi procedure, provides a rationale for its use, describes the distinctive features, reviews key points of contention and provides an indication of both past and present uses     

Quality of Care at School-Aged Child-Care Programs: Regulatable Features, Observed Experiences, Child Perspectives, and Parent Perspectives

This study investigates children's experiences at 30 school-aged child-care (SACC) programs. Regulatable features such as total enrollment, child-staff ratio, and staff education were assessed via director report. Observers recorded positive/neutral and negative staff-child interactions, and rated programs in terms of flexibility and age appropriateness. Negative staff-child interactions were more frequent when child-staff ratios were larger and when staff had less formal education. The presence of a greater number of different types of program activities was associated with staff having more frequent positive interactions with children and with observers rating programs as flexible and age appropriate. These regulatable and observed features were examined in relation to children's ( N = 180) and parents' ( N = 152) perceptions of program psychosocial climate. Children's reports of overall climate, emotional support from staff, and autonomy/privacy provisions were predicted by program features. Children reported poorer program climate when programs had larger enrollments and when observers recorded more frequent negative staff-child interactions. Children had more positive program perceptions when programs offered a greater variety of activities. Children's reports of program climate in addition to observed child-staff ratios were associated with parental perceptions of the programs. Parents had more positive perceptions when child-adult ratios were smaller and when their children reported more positive climates. This study suggests a convergence between observer, child, and parent about factors contributing to quality of after-school programs.
