Playful Talk: Negotiating Opportunities to Learn in Collaborative Groups

This case study examines the role of playful talk in negotiating the “how” of collaborative group work in a 6th-grade science classroom. Here we develop and test a Vygotsky-derived hypothesis that postulates playful talk as a mechanism for identity exploration and group status negotiation. Our findings indicate that students utilized the playful talk genre as a means to (a) position themselves and others as more or less competent within the group in order to create or foreclose opportunities to learn, (b) maintain and strengthen bonds that were developing within the group toward the goal of achieving higher levels of coordination and opportunities to learn, and (c) pivot toward a self-selected identity aimed sometimes at affecting one’s status within the group. Taken together, these 3 playful talk functions allowed the group to manage tensions that arose as a result of periods of low coordination and to open opportunities to learn for lower status group members. This study contributes to researchers’ understanding of affective aspects of collaborative learning, which are theorized as foundational to success in such endeavors.     

Everything Old is New Again: The Criminology/Criminal Justice Freshman Research Seminar

This is a report of an action-research project undertaken in tandem with the development of a new freshman seminar in criminology and criminal justice. In the freshman seminar the goal is to teach the research, critical thinking and writing skills that are the underpinnings of scholarship and good citizenship. Utilizing a unique approach, this class focuses on resources available through the University library and is taught by a professor, two librarians and a graduate teaching assistant. We hypothesize that freshmen who experience this seminar will show improvement in critical thinking skills, and that this will contribute to greater levels of academic success. This report describes the educational innovation (seminar) in sufficient detail to make replication possible, and presents preliminary findings that indicate the seminar enhances research and writing skills, fosters ability to think critically, and has a positive influence on students’ academic careers.     

A Comparison of Training Methods on the Acquisition of Automotive Product Knowledge

The purpose of this study was to compare the effects of a traditional training program with a fluency‐building training program on the acquisition of automotive product knowledge in a lab setting. The effects were assessed by how accurately and quickly participants responded on a product‐knowledge test. Results indicated that participants who completed the fluency training responded faster and more accurately than control groups immediately after the study. However, the difference between the fluency group and the group that received study objectives disappeared when retention was assessed several weeks after training. The difference remained between these groups and a group that did not receive study objectives. The results were used to modify globally delivered training. This study extended previous studies by examining the effects of training designed to teach product knowledge to sales representatives in automotive dealerships and illustrates the benefits of collaboration between academic researchers and professional trainers.     

Digital media as a reflective tool: creating appropriate spaces for students to become introspective

Global citizenship and competency development have become integral parts of political, economic and education discourses. This is particularly true in the USA, where higher education institutions are answering the global citizenship call through the promotion of short-term study abroad. Unfortunately, the ‘just do it’ analogy too often influences the ideology of study abroad, whereby simply providing students with an international experience is perceived to be sufficient in shaping global citizenship. Global citizenship, as an educational outcome, is optimally facilitated when educational experiences are married with appropriate pedagogy, including the shaping of subsequent understandings and actions with critical reflection. We postulate that reflective experiences can be further enhanced by meeting students on the platforms and forums where they live, communicate and already engage. Specifically, this communication, using the context of short-term study abroad programmes, will argue that: (1) critical reflection is an essential step to fostering global citizenship and (2) digital story telling (mobile pedagogy) can be a powerful tool for enriching the critical reflection process.     

Social Networks and Archival Context: From Project to Cooperative Archival Program

This article highlights the objectives and outcomes of the multi-year Social Networks and Archival Context (SNAC) research and demonstration project and discusses related developments to establish a large-scale sustainable cooperative for maintaining information about creators of archival collections, leveraging the Encoded Archival Context—Corporate Bodies, Persons, and Families (EAC-CPF) standard. The article discusses processes developed to derive EAC-CPF records from existing EAD finding aids, MARCXML records, and original authority records, enrichment of those records from other sources, and the creation of a prototype research resource, providing integrated access to dispersed archival collections and the social-historical context of the collections.     

Artefacts at the liquid interface and their impact in miniaturized biochemical assay

Droplet microfluidic technology has the potential to significantly reduce reagent use, and therefore, lower costs of assays employed in drug discovery campaigns. In addition to the reduction in costs, this technology can also reduce evaporation and contamination which are often problems seen in miniaturized microtitre plate formats. Despite these advantages, we currently advise caution in the use of these microfluidic approaches as there remains a lack of understanding of the artefacts of the systems such as reagent partitioning from droplet to carrier oil and interaction of the biological reagents with the water-oil interface. Both types of artefact can lead to inaccurate and misleading data. In this paper, we present a study of the partitioning of a number of drug-like molecules in a range of oils and evidence of protein binding at the water-oil interface which results in reduced activity of a cytochrome P450 enzyme. Data presented show that the drug-like molecules partitioned the least into fluorocarbon oils and the interaction of the 1A2 cytochrome at the water-oil interface resulted in a lower or complete absence of enzyme activity. This loss of activity of cytochrome 1A2 could be restored by the use of secondary blocking proteins although changes in the pharmacology of known 1A2 inhibitors were observed. The artefacts described here due to reagents partitioning into the carrier oil or protein binding at the water-oil interface significantly impact the potential use of these microfluidic systems as a means to carry out miniaturized biological assays, and further work is needed to understand the impact and reduction of these phenomena.     

The match demands of international rugby sevens

The purpose of this study was to quantify the global match demands of international rugby sevens and to compare the match demands of forwards and backs, and between tournament rounds. To assess the match demands, global positioning system (GPS) and video analysis were collected from 27 international rugby sevens players from the same team across an entire International Rugby Board Sevens World Series season. Differences in running demands and match activities between forwards and backs were mostly trivial and small (ES = 0.05–0.84) while differences in running demands and match activities between Pool and Cup rounds were trivial (ES = 0.001–0.12). Cup round matches showed an increase in long-duration ball-in-play sequences (proportion ratio 0.46). These findings suggest international rugby sevens forwards and backs experience similar match demands while overall match demands remain consistent across tournament rounds.     

The effect of heavy resistance exercise on repeated sprint performance in youth athletes

This investigation assessed whether prior heavy resistance exercise would improve the repeated sprint performance of 16 trained youth soccer players (Age 17.05 ± 0.65 years; height 182.6 ± 8.9 cm; body mass 77.8 ± 8.2 kg). In session 1, individual 1 repetition max was measured utilising a squat movement. In sessions 2 and 3, participants performed a running-based repeated anaerobic sprint test with and without prior heavy resistance exercise of 91% of their 1 repetition max. Times were recorded for each of the 6 sprints performed in the repeated sprint test and summed to provide total time. T-tests compared the two exercise conditions via differences in corresponding sprint times and total time. Analysis revealed significantly reduced total time with use of heavy resistance exercise (33.48 (±1.27) vs. 33.59 (±1.27); P = 0.01). Sprints 1 (P = 0.05) and 2 (P = 0.02) were also faster in the heavy resistance exercise condition (5.09 (±0.16) vs. 5.11 (±0.16) and 5.36 (±0.24) vs. 5.45 (±0.26) seconds respectively) although no other differences were shown. Findings demonstrate improved sprint times of trained adolescent soccer players after heavy resistance exercise although benefits appear not as sustained as in adult participants.     

Archival representations of immigration and ethnicity in North American history: from the ethnicization of archives to the archivization of ethnicity

This article traces the representations of ethnicity and immigration in mainstream American and Canadian archives since the 1950s. It identifies three main periods of evolution of these ethnic archives: the era prior to the civil rights movement, the 1960–1980s and the 1990s and beyond. Relying on an understanding of archival collections as social constructions anchored in specific historical contexts, the article considers the various political, economic, social and technological factors that affected ethnic archives over time, especially as they relate to changing scholarly and popular conceptions of ethnicity in North America. It pays particular attention to the impact of historical scholarship in fields related to immigration and ethnicity and of postmodernist archival theories that challenge the traditional view of archives as evidence of the past. It suggests that the relationship between ethnic archives and their historical context is dialectical: not only are they affected by the context in which they are developed and managed, but they also have an impact on that context as they favor certain conceptions of ethnicity and types of ethnic groups at the expense of others. Both curators and users of archival materials should therefore pay closer attention to the history of the processes that went into the construction of these archives to avoid falling victims to the illusion of ethnic authenticity.
