Feedback on feedback practice: perceptions of students and academics

While feedback is widely considered central to student learning, students across the higher education sector commonly report dissatisfaction with the feedback they receive. In contrast, academics often feel they provide quality and informative feedback. This article explores and compares the perceptions of students and academics with regard to feedback practice. The paper presents the results of questionnaire surveys conducted with academics and students at the School of the Built Environment, Liverpool John Moores University. It highlights the perceptions of academics and students with regard to preferences for different types of feedback, timeliness of feedback, students’ engagement and interest in feedback, quality feedback and satisfaction with current practice. The findings indicate a significant discord between staff and students in relation to certain aspects of feedback practice, namely opinions on students’ engagement and interest in feedback, satisfaction with current practice and feedback preference. Similarities in viewpoints were also found in relation to quality feedback.     

Measurement Invariance of a School Readiness Screener for Use in Preschool and Kindergarten

Research Findings: Public policy has increasingly focused on expansion of preschool access for underserved students and systematic evaluation of preschool quality and students’ readiness for school. However, such evaluation is limited by a lack of thoroughly validated assessments for use with preschool populations. The present study examined the measurement and structural invariance of the Kindergarten Student Entrance Profile (KSEP) across kindergarten and prekindergarten groups to evaluate its potential use across developmental groups. Participants included 522 kindergarten and 548 prekindergarten students in central California. Invariance was tested by fitting a series of multiple-groups confirmatory factor analysis models with parameter constraints across groups. Results indicated that measurement and structural parameters of the KSEP were invariant across kindergarten and prekindergarten groups. Prekindergarten means on both Social–Emotional Readiness and Cognitive Readiness were significantly lower than kindergarten means. Practice or Policy: These results suggest that the KSEP may potentially be used with prekindergarten students to assess school readiness and inform intervention before kindergarten entry.     

Identifying the Prevalence of Courses on Mental Illness in Criminal Justice Education

Persons with Mental Illness (PMIs) require unique consideration and individualized attention in the criminal justice system. Research has demonstrated the prevalence with which police come into contact with these individuals, the unique considerations made by courtrooms serving PMIs, the overrepresentation of PMIs in correctional settings, and the problems PMIs experience when reentering the community from incarceration. Given the growth of attention to this area, and the increased reality of challenges that criminal justice professionals encounter when working with PMIs, this paper explores the prevalence of courses on mental illness in criminal justice undergraduate programs in the United States. The current review of over 640 curricula in the United States illustrates that courses devoted solely to the topic of mental illness in the criminal justice system are particularly rare. The importance of offering more courses in the interface between mental illness and criminal justice for future professionals in the field is discussed.     

Do specific relevance instructions promote transfer appropriate processing?

This study examined whether specific relevance instructions affect transfer appropriate processing. Undergraduates (n = 52) were randomly assigned to one of three pre-reading question conditions that asked them what-questions, why-questions, or to read for understanding (i.e., control condition). There were no differences in reading time across conditions for sentences targeted by the pre-reading questions. There were three main findings with respect to cued recall. First, participants in the experimental conditions did better on questions that had greater similarity to relevance instructions than questions that had lesser similarity to relevance instructions. Second, participants in the experimental conditions did better on questions that had greater similarity to relevance instructions than the participants in the other conditions on those same questions. Third, participants in the control condition recalled equal amounts of information for both question. The results suggest that specific relevance instructions promote transfer appropriate processing and affect the quality of memory for text.     

Out on the Web: The Relationship between Campus Climate and GLBT-related Web-based Resources in Academic Libraries

This article explores the relationship between the perceived campus environment for gay, lesbian, bisexual, and transgender (GLBT) students at colleges and universities and how academic libraries have deployed GLBT-related resources on the Web. Recommendations are made for increasing GLBT-related materials and information in academic libraries.     

Real time search on the web: Queries,topics, and economic value

Real time search is an increasingly important area of information seeking on the Web. In this research, we analyze 1,005,296 user interactions with a real time search engine over a 190 day period. Using query log analysis, we investigate searching behavior, categorize search topics, and measure the economic value of this real time search stream. We examine aggregate usage of the search engine, including number of users, queries, and terms. We then classify queries into subject categories using the Google Directory topical hierarchy. We next estimate the economic value of the real time search traffic using the Google AdWords keyword advertising platform. Results shows that 30% of the queries were unique (used only once in the entire dataset), which is low compared to traditional Web searching. Also, 60% of the search traffic comes from the search engine’s application program interface, indicating that real time search is heavily leveraged by other applications. There are many repeated queries over time via these application program interfaces, perhaps indicating both long term interest in a topic and the polling nature of real time queries. Concerning search topics, the most used terms dealt with technology, entertainment, and politics, reflecting both the temporal nature of the queries and, perhaps, an early adopter user-based. However, 36% of the queries indicate some geographical affinity, pointing to a location-based aspect to real time search. In terms of economic value, we calculate this real time search stream to be worth approximately US $33,000,000 (US $33 M) on the online advertising market at the time of the study. We discuss the implications for search engines and content providers as real time content increasingly enters the main stream as an information source.     

Conveying quality and value in emerging industries: Star scientists and the role of signals in biotechnology

This paper addresses the role that scientific status plays in initial public offerings of technology focused firms. The paper builds on the literature of the sociology of science as well as the work of Spence (1974) and Podolny (1993) and argues that the presence of a Nobel laureate affiliated with a firm making an IPO provides a signal of firm quality to potential investors. Moreover, and building on the work of Podolny and Scott Morton (1999) and Stuart et al. (1999) we hypothesize that the importance of status diminishes as other measures of firm quality become available. We test our hypothesis for two periods of initial public offerings in biotechnology. We document that there is a clear difference in “maturity” of the firms across the two windows on a number of metrics. Consistent with our hypothesis that Nobel laureates play an important role as a non-financial signal of firm quality, we find that first-window firms with a Nobel laureate affiliate realize greater IPO proceeds in the amount of $24 million. In the second window the amount of money raised is not significantly different between Nobel and non-Nobel firms. This finding is consistent with the signaling literature that argues that the importance of a signal is inversely related to the availability of cogent information on firm quality. Consistent with this view, we also find a change between the two windows in the importance of other non-financial metrics used to convey value. Our research is one of the first to examine the dynamic nature of signals. Because we are unable to distinguish the extent to which the reduction in uncertainty at the firm level is correlated with the reduction of uncertainty at the industry level, the question remains as to the extent to which the diminished importance of signals in our second period is due to a change in market uncertainty versus a change in firm uncertainty.     

Separation and enrichment of sodium-motile bacteria using cost-effective microfluidics

Many motile bacteria are propelled by the rotation of flagellar filaments. This rotation is driven by a membrane protein known as the stator-complex, which drives the rotor of the bacterial flagellar motor. Torque generation is powered in most cases by proton transit through membrane protein complexes known as stators, with the next most common ionic power source being sodium. Sodium-powered stators can be studied through the use of synthetic chimeric stators that combine parts of sodium- and proton-powered stator proteins. The most well studied example is the use of the sodium-powered PomA-PotB chimeric stator unit in the naturally proton-powered Escherichia coli. Here we designed a fluidics system at low cost for rapid prototyping to separate motile and non-motile populations of bacteria while varying the ionic composition of the media and thus the sodium-motive force available to drive this chimeric flagellar motor. We measured separation efficiencies at varying ionic concentrations and confirmed using fluorescence that our device delivered eightfold enrichment of the motile proportion of a mixed population. Furthermore, our results showed that we could select bacteria from reservoirs where sodium was not initially present. Overall, this technique can be used to implement the selection of highly motile fractions from mixed liquid cultures, with applications in directed evolution to investigate the adaptation of motility in bacterial ecosystems.     

Understanding the rationale for preschool physical education: implications for practitioners' and children's embodied practices and subjectivity formation

This paper provides an overview of selected academic research literature that underpins contemporary preschool physical education. We highlight and interrogate diverse rationales and beliefs that serve to influence and structure preschool physical education in various forms. We speculate as to how preschool practitioners and children might engage in specific practices relative to these discourses. Our consideration of preschool physical education discourses relies upon a Foucaultian analysis of the major techniques of power and also raises possibilities of conceptualising subjectivity formation through his concept of the ‘technologies of the self’. Discourses related to motor skill development, play and physical activity, in particular, appear to be prevalent in the selected literature, along with a related pedagogical discourse concerning ‘structure and freedom’. These sometimes competing discourses arguably underpin competing agendas reflecting those who advocate supporting children's free play and those who propose more structured and interventionist practices in relation to young children's physical activity. We conclude that these diverse approaches lend themselves to interpretation and negotiation in the context of preschool physical education, with specific consequences for the embodied experiences and subjectivities of preschool practitioners and children.
