Can creative podcasting promote deep learning? The use of podcasting for learning content in an undergraduate science unit

This paper examines the effect of a podcasting task on the examination performance of several hundred first‐year chemistry undergraduate students. Educational researchers have established that a deep approach to learning that promotes active understanding of meaning can lead to better student outcomes, higher grades and superior retention of knowledge over time. We attempted to promote such an approach by setting a task that involved student collaboration, contextualisation of content, and communication through new media, specifically creative podcasting. Examination results were used as a source of empirical evidence of changes in understanding and retention that occurred for students who completed this task. In comparing results across 2 years on similar questions related to the podcasting topics, we found a statistically significant improvement after introduction of the podcasting task on the questions related to one of the topics on which students had actively created their own podcasts (“acids & bases”), but not on the other (“oxidisation and reduction”). Improved learning outcomes in the form of better understanding and retention over time in at least one case suggest that under some circumstances creative podcasting may indeed help to promote a deep learning approach.     

Determining optimal trial size using sequential analysis

When characterising typical human movement profiles, the optimal number of trials analysed for each participant should ensure a stable mean. Sequential analysis is one method able to establish the number of trials to stability by assessing a moving point mean against a set bandwidth. As the total trial number determining this bandwidth is selected arbitrarily, the effect of applying different total trial numbers on the results of sequential analysis was investigated. Twenty participants performed 30 trials of overarm throwing, and sequential analyses were applied to three dimensional (3-D) kinematic data over 10, 20 and 30 trial numbers. We found a total of 20 to be the preferred trial number for sequential analyses. Erroneous results were produced consistently by 10 trial number groups, while moving point means were statistically unchanged after the 10th trial. Subsequently, sequential analyses were applied to 20 trials to establish trials to stability in discrete and time series elements of the 3-D kinematic data. The results suggest that a trial size between 13 and 17 provides stable means for overarm throwing kinematics.     

Taking library instruction into the online environment: one health sciences library's experience

In 2012, an academic health sciences library serving a large research university and medical center introduced synchronous online training for a diverse group of users, including clinicians, researchers, faculty, and distance students. Participants in these “Express Training” classes completed two surveys to assess their experiences. Survey results indicated classes were well received but revealed some areas for improvement. Included are issues that should be considered when implementing online library instruction to meet the diverse needs of academic health sciences library users. Given the popularity of online training among on-campus and distance users, it will be continued and expanded.     

Surveillance in ubiquitous network societies: normative conflicts related to the consumer in-store supermarket experience in the context of the Internet of Things

The Internet of Things (IoT) is an emerging global infrastructure that employs wireless sensors to collect, store, and exchange data. Increasingly, applications for marketing and advertising have been articulated as a means to enhance the consumer shopping experience, in addition to improving efficiency. However, privacy advocates have challenged the mass aggregation of personally-identifiable information in databases and geotracking, the use of location-based services to identify one’s precise location over time. This paper employs the framework of contextual integrity related to privacy developed by Nissenbaum (Privacy in context: technology, policy, and the integrity of social life. Stanford University Press, Stanford, 2010) as a tool to understand citizen response to implementation IoT-related technology in the supermarket. The purpose of the study was to identify and understand specific changes in information practices brought about by the IoT that may be perceived as privacy violations. Citizens were interviewed, read a scenario of near-term IoT implementation, and were asked to reflect on changes in the key actors involved, information attributes, and principles of transmission. Areas where new practices may occur with the IoT were then highlighted as potential problems (privacy violations). Issues identified included the mining of medical data, invasive targeted advertising, and loss of autonomy through marketing profiles or personal affect monitoring. While there were numerous aspects deemed desirable by the participants, some developments appeared to tip the balance between consumer benefit and corporate gain. This surveillance power creates an imbalance between the consumer and the corporation that may also impact individual autonomy. The ethical dimensions of this problem are discussed.     

Self-reported ability assessment in rock climbing

Level of ability within rock climbing is generally expressed in terms of a "best ascent", rated using various grading systems within the sport. The most common method of obtaining this information is via self-report. The aim of this study was to examine the validity of self-reported climbing grades. Twenty-nine competitive rock climbers (17 males, 12 females) were first asked to report their current (defined as within the last 12 months) best on-sight lead ascent grade (Aus/NZ). The participants then climbed a specifically designed indoor route, under on-sight conditions (one attempt, no route practice or preview), to obtain an assessed grade. The route increased in difficulty, and was such that the distance achieved by the climber corresponded to a particular grade. The mean (±standard deviation) self-reported and assessed grade was 22.6?±?3.4 and 22.0?±?3.0 (Aus/NZ) respectively. Despite slight over- and underestimations in males and females respectively, there was no statistically significant difference between self-reported and assessed on-sight climbing grades. The results of this study suggest that self-reported climbing grades provide a valid and accurate reflection of climbing ability.     

Teenage Kicks: Exploring cultural value from a youth perspective

In contemporary accounts of cultural value, young people's perspectives are often restricted to analyses of their encounters with formal cultural institutions or schools or to debates surrounding the cultural implications of new digital spaces and technologies. Other studies have been dominated by instrumental accounts exploring the potential economic benefit and skills development facilitated by young people's cultural encounters and experiences. In this paper we examine the findings of a nine month project, which set out to explore what cultural value means to young people in Bristol. Between October 2013 and March 2014, the Arts and Humanities Research Council “Teenage Kicks” project organised 14 workshops at 7 different locations across the city, with young people aged 11–20. Working in collaboration with a network of cultural and arts organisations, the study gathered a range of empirical data investigating the complex ecologies of young people's everyday/“lived” cultures and values. Young people's own accounts of their cultural practices challenge normative definitions of culture and cultural value but also demonstrate how these definitions act to reproduce social inequalities in relation to cultural participation and social and cultural capital. The paper concludes that cultural policy-makers should listen and take young people's voices seriously in re-imaging the city's cultural offer for all young people.     

The Role of Executive Functions in Socioeconomic Attainment Gaps: Results From a Randomized Controlled Trial

The socioeconomic attainment gap in mathematics starts early and increases over time. This study aimed to examine why this gap exists. Four-year-olds from diverse backgrounds were randomly allocated to a brief intervention designed to improve executive functions (N = 87) or to an active control group (N = 88). The study was preregistered and followed CONSORT guidelines. Executive functions and mathematical skills were measured at baseline, 1 week, 3 months, 6 months, and 1 year posttraining. Executive functions mediated the relation between socioeconomic status and mathematical skills. Children improved over training, but this did not transfer to untrained executive functions or mathematics. Executive functions may explain socioeconomic attainment gaps, but cognitive training directly targeting executive functions is not an effective way to narrow this gap.     

Evaluating the effectiveness of KooLKIDS: An interactive social emotional learning program for Australian primary school children

The effectiveness of universal social emotional learning (SEL) programs are dependent on the incorporation of best practice principles, including an evaluative component. In the present study, the effects of a best practice, teacher-led SEL program was examined with 854 children aged 8–12 years. KooLKIDS uses an interactive multimedia format and animated character to help children develop their emotion regulation capacities, social and friendship skills, empathy and compassion for others, and self-esteem. A quasi-experimental waitlist-control design was used to examine the impact of KooLKIDS on social and emotional competence, behavioral and emotional problems, academic achievement and effort. Hierarchical linear modeling demonstrated significant increases in social and emotional competence, and reductions in internalizing and externalizing problems in children post KooLKIDS program in the intervention group. The findings suggest that KooLKIDS has strong potential as a teacher-led, classroom-based, structured program for enhancing children's social and emotional learning.
