Pedagogical devices as children’s social care levers: A study of social care workers’ attitudes towards boarding schools to care for and educate children in need

It has been proposed that boarding schools in England can be used to provide a stable education and care environment for vulnerable children in need, and the government is expanding their use. However, for vulnerable children to be placed in boarding schools, social workers will need to be willing to contemplate boarding as a viable care option. In this study we interviewed N = 21 social care practitioners including directors, senior and middle managers, frontline social workers, social worker‐academics and family support workers who work with vulnerable children. Using thematic analysis of the transcribed interviews, seven major themes identified a range of issues and concerns held by social care workers about placing vulnerable children in boarding schools. We present these themes and consider the issues that will have to be addressed prior to changes in policy and practice. The study concludes that many of those within the social work profession are unlikely to consider boarding as an intervention for children in need. Further research in this area is a matter of urgency

Low-Attaining Secondary School Mathematics Students’ Perspectives on Recommended Teaching Strategies

Recent research syntheses have identified several potentially high-leverage teaching strategies for improving low-attaining secondary school students’ learning of mathematics. These strategies include the structured use of representations and manipulatives and an emphasis on derived facts and estimation. This paper reports on 70 semi-structured interviews conducted with low-attaining students in Years 9–10 (ages 13–15) in England. The interviews addressed the students’ perceptions of learning mathematics and the teaching strategies that they experienced and believed were most helpful. Many students reported rarely using number lines, not spontaneously estimating answers and being unfamiliar with derived facts. During the interviews, with minimal direction, students often showed that they were well able to make use of these strategies; however, they did not report making spontaneous use of them independently. We conclude that many of the most well-evidenced and recommended strategies to support low-attaining students in mathematics appear to be unfamiliar and unvalued, and we discuss how this might be addressed

Identification of Off-Flavor Compounds in Beef Round and Chuck Muscles

Volatile off-flavor compounds are present in beef. Using purge and trap gas chromatography and mass spectrometry, some volatile compounds were shown to have different concentrations in normal-flavored beef, compared to samples with liver-like off-flavor. Most of the compounds, like pentanol, hexanal, hexanol, 1–octen–3–ol, and nonanol, are associated with lipid oxidation. The compounds, β-pinene and 1-octen-3-ol were in higher concentration in the liver-like samples in all muscles tested. Several, small, unidentified peaks also differed between samples. Determination of the possible origins of these compounds may improve the quality and consistency of beef products

Increasing Collegiate Flight Training Fleet Utilization Through the Use of an Aircraft Assignment Algorithm

The operational efficiency of fleet aircraft employed for student flight training in collegiate aviation programs is strongly influenced by scheduling, among other factors. The average utilization rate for the fleet operated by the Purdue University School of Aviation and Transportation Systems was found to be 24% (Avery, 2014), and there is no data to suggest that that this rate is atypical in similar institutional programs. Mott and Bullock (2015) identified several means by which the utilization rate could be increased, and improvements in the dispatch and scheduling process were a key component of those recommendations. This article describes a scheduling algorithm that was implemented at Purdue University in the fall semester of 2015. The algorithm is a linear programming technique that incorporates optimization constraints unique to collegiate flight training operations. The resulting improvements in aircraft utilization will facilitate an increased matriculation rate of students into the flight program, thereby allowing the allocation of fixed costs over a wider user base and the reduction of overall program fees for all students. Those improvements are validated through measurement of the reduction of the cumulative turn times between aircraft operations

Trial Evaluation Protocol: SMART Spaces (Spaced Learning Revision Programme)

This evaluation protocol describes the evaluation of SMART Spaces: Spaced Learning Revision Programme (SMART Spaces Revision), an efficacy trial funded by the Education Endowment Foundation (EEF), designed to investigate the effect of the intervention on the chemistry element of the GCSE double award science. The evaluation will consist of a twoarm randomised controlled trial testing the SMART Space Revision intervention against a ‘business as usual’ control and will include a mixed methods implementation and process evaluation (IPE). The trial will take place over the 2018/19 academic year, with randomisation taking place in two stages in October and December 2018 and the delivery of the intervention in schools during April and May 2019, following teacher training and coaching sessions over the period December 2018 to March 2019. Final publication of the results will be in Summer 2020. This protocol outlines the rationale for the project, describes the intervention using the TIDieR framework and outlines the methods of data collection and analysis for the impact evaluation, the IPE and the cost evaluation
