Feeding back to feed forward:formative assessment as a platform for effective learning

Students construct meaning through relevant learning activities (Biggs, 2003) which are largely determined by the type, amount, and timing of feedback (Carless, 2006). The aim of the present study was to develop a greater awareness and understanding of formative assessment and feedback practices and their relationship with learning. During 2011 five focus group discussions were undertaken with students and academic staff involved with a range of modules and degree pathways at a UK University. Three of the focus groups were with undergraduate students (one at each level of study), and one was with taught postgraduate students. Discussions focussed on integration of formative assessment and feedback into modules, as well as an exploration of the effectiveness of feedback on future learning. The findings revealed that in order to emphasise continuous learning – feeding back to feed forward (Rushton, 2005) – and to encourage self-regulated learning (Nicol & Macfarlane-Dick, 2006), students need to have opportunities to make mistakes and to learn from them prior to summative assessment (through formative assessment and feedback). There was also firm evidence of different approaches to learning, emphasising in particular the transitional importance of the first year of study as the foundation upon which future achievement is built

The ‘oldest tricks in the book’ don’t work! Reports of burglary by DUMA detainees in Western Australia

Explores the methods and motivations of those actively involved in committing burglaries. Foreword Research investigating the methods and motivations of burglars has typically focused on incarcerated offenders. The Australian Institute of Criminology’s Drug Use Monitoring in Australia (DUMA) program provided an opportunity for the authors to explore the methods and motivations of those actively involved in committing burglaries, whether or not they had actually been caught or detained for that offence. The findings support Routine Activity Theory, indicating that offenders consider a number of factors in determining whether a property will be targeted for a break and enter offence. As might be expected, opportunistic burglars choose easy to access properties, stay a minimum length of time and take goods that can be disposed of easily. It was concluded that simple prevention strategies could minimise the risk of becoming a victim of opportunistic burglary, which also has implications for law enforcement, the security industry and insurance agencies

Very Low Mass Stellar and Substellar Companions to Solar-like Stars from MARVELS. II. A Short-period Companion Orbiting an F Star with Evidence of a Stellar Tertiary and Significant Mutual Inclination

We report the discovery via radial velocity (RV) measurements of a short-period (P = 2.430420 ± 0.000006 days) companion to the F-type main-sequence star TYC 2930-00872-1. A long-term trend in the RV data also suggests the presence of a tertiary stellar companion with P > 2000 days. High-resolution spectroscopy of the host star yields T_(eff) = 6427 ± 33 K, log g = 4.52 ± 0.14, and [Fe/H] = –0.04 ± 0.05. These parameters, combined with the broadband spectral energy distribution (SED) and a parallax, allow us to infer a mass and radius of the host star of M_1 = 1.21 ± 0.08 M_☉ and R_1 = 1.09^(+0.15)_(–0.13) R_☉. The minimum mass of the inner companion is below the hydrogen-burning limit; however, the true mass is likely to be substantially higher. We are able to exclude transits of the inner companion with high confidence. Further, the host star spectrum exhibits a clear signature of Ca H and K core emission, indicating stellar activity, but a lack of photometric variability and small v sin I suggest that the primary's spin axis is oriented in a pole-on configuration. The rotational period of the primary estimated through an activity-rotation relation matches the orbital period of the inner companion to within 1.5 σ, suggesting that the primary and inner companion are tidally locked. If the inner companion's orbital angular momentum vector is aligned with the stellar spin axis as expected through tidal evolution, then it has a stellar mass of ~0.3-0.4 M_☉. Direct imaging limits the existence of stellar companions to projected separations <30 AU. No set of spectral lines and no significant flux contribution to the SED from either companion are detected, which places individual upper mass limits of M_([2,3]) ≾ 1.0 M_☉, provided they are not stellar remnants. If the tertiary is not a stellar remnant, then it likely has a mass of ~0.5-0.6 M_☉, and its orbit is likely significantly inclined from that of the secondary, suggesting that the Kozai-Lidov mechanism may have driven the dynamical evolution of this system

Researching a segmented market:reflections on telephone interviewing

Purpose The purpose of this paper was to review the effectiveness of telephone interviewing for capturing data and to consider in particular the challenges faced by telephone interviewers when capturing information about market segments. Design/methodology/approach The platform for this methodological critique was a market segment analysis commissioned by Sport Wales which involved a series of 85 telephone interviews completed during 2010. Two focus groups involving the six interviewers involved in the study were convened to reflect on the researchers’ experiences and the implications for business and management research. Findings There are three principal sets of findings. First, although telephone interviewing is generally a cost-effective data collection method, it is important to consider both the actual costs (i.e. time spent planning and conducting interviews) as well as the opportunity costs (i.e. missed appointments, “chasing participants”). Second, researchers need to be sensitised to and sensitive to the demographic characteristics of telephone interviewees (insofar as these are knowable) because responses are influenced by them. Third, the anonymity of telephone interviews may be more conducive for discussing sensitive issues than face-to-face interactions. Originality/value The present study adds to this modest body of literature on the implementation of telephone interviewing as a research technique of business and management. It provides valuable methodological background detail about the intricate, personal experiences of researchers undertaking this method “at a distance” and without visual cues, and makes explicit the challenges of telephone interviewing for the purposes of data capture

Discovery of a Low-mass Companion to a Metal-rich F Star with the MARVELS Pilot Project

We report the discovery of a low-mass companion orbiting the metal-rich, main sequence F star TYC 2949-00557-1 during the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS) pilot project. The host star has an effective temperature T_(eff) = 6135 ± 40 K, logg = 4.4 ± 0.1, and [Fe/H] = 0.32 ± 0.01, indicating a mass of M_⊙ = 1.25 ± 0.09 M_⊙ and R = 1.15 ± 0.15 R_⊙. The companion has an orbital period of 5.69449 ± 0.00023 days and straddles the hydrogen burning limit with a minimum mass of 64 M_J , and thus may be an example of the rare class of brown dwarfs orbiting at distances comparable to those of "Hot Jupiters." We present relative photometry that demonstrates that the host star is photometrically stable at the few millimagnitude level on time scales of hours to years, and rules out transits for a companion of radius ≳ 0.8 R_J at the 95% confidence level. Tidal analysis of the system suggests that the star and companion are likely in a double synchronous state where both rotational and orbital synchronization have been achieved. This is the first low-mass companion detected with a multi-object, dispersed, fixed-delay interferometer

A Model for Data Citation in Astronomical Research using Digital Object Identifiers (DOIs)

Standardizing and incentivizing the use of digital object identifiers (DOIs) to aggregate and identify both data analyzed and data generated by a research project will advance the field of astronomy to match best practices in other research fields like geosciences and medicine. Increase in the use of DOIs will prepare the discipline for changing expectations among funding agencies and publishers, who increasingly expect accurate and thorough data citation to accompany scientific outputs. The use of DOIs ensures a robust, sustainable, and interoperable approach to data citation in which due credit is given to researchers and institutions who produce and maintain the primary data. We describe in this work the advantages of DOIs for data citation and best practices for integrating a DOI service in an astronomical archive. We report on a pilot project carried out in collaboration with AAS Journals. During the course of the 1.5 year pilot, over 75% of submitting authors opted to use the integrated DOI service to clearly identify data analyzed during their research project when prompted at the time of paper submission.Comment: 13 pages, 3 figures.

The experience of competition stress and emotions in cricket

The purpose of the study was to conduct an in-depth examination of the stress and emotion process experienced by three sub-elite level male cricketers over a series of five competitive performances. Using reflective diaries and follow up semi-structured interviews, the findings highlighted the impact of appraisal, coping, and emotion on performance, with perceptions of control and self-confidence emerging as variables that can influence the emotive and behavioral outcomes of a stressful transaction. Post-performance, guided athlete reflection was advanced as a valuable tool in the production and application of idiographic coping behaviors that could enhance perceptions of control and self-confidence and influence stress and emotion processes

Agreement in student performance in assessment

Assessment of a student’s performance on a particular module may often be thought of as a single evaluation of the extent to which the student has met some or all of the module’s learning outcomes. More helpfully, however, when there is more than one assessment task in a particular module, it may be thought of as the combination of different assessment tasks (whatever the weighting attached to each of them). In this sense, the level of agreement between performances on the different tasks may elucidate the nature of overall student performance further still. Typically, assessment tasks within a module tend not to be of the same kind; often they are complementary, sometimes through the use of different media. The primary aim of the present study was to investigate agreement in student performance between assessment tasks within two modules

A search for rapidly pulsating hot subdwarf stars in the GALEX survey

NASA's Galaxy Evolution Explorer (GALEX) provided near- and far-UV observations for approximately 77 percent of the sky over a ten-year period; however, the data reduction pipeline initially only released single NUV and FUV images to the community. The recently released Python module gPhoton changes this, allowing calibrated time-series aperture photometry to be extracted easily from the raw GALEX data set. Here we use gPhoton to generate light curves for all hot subdwarf B (sdB) stars that were observed by GALEX, with the intention of identifying short-period, p-mode pulsations. We find that the spacecraft's short visit durations, uneven gaps between visits, and dither pattern make the detection of hot subdwarf pulsations difficult. Nonetheless, we detect UV variations in four previously known pulsating targets and report their UV pulsation amplitudes and frequencies. Additionally, we find that several other sdB targets not previously known to vary show promising signals in their periodograms. Using optical follow-up photometry with the Skynet Robotic Telescope Network, we confirm p-mode pulsations in one of these targets, LAMOST J082517.99+113106.3, and report it as the most recent addition to the sdBVr class of variable stars.Comment: 11 Pages, 8 Figures, Accepted for publication in the Astrophysical Journa
