“Here the Scientists Explain What I Said.” Coordination Practices Elicited During the Enactment of the Results and Discussion Sections of Adapted Primary Literature

Adapted primary literature (APL) is a novel text genre that retains the authentic characteristics of primary literature. Learning through APL represents an educational intervention with an authentic scientific context. In this case study, we analyzed the 80-min discourse developed during the enactment of an article from an APL-based curriculum in biotechnology in one class, and examined epistemic practices used by students during their meaning-making of the Results and Discussion sections of the article. Specifically, we examined coordination practices, by which students connected elements belonging to different epistemic status or context (theory, data, experimental stages, biotechnological applications and text). The application of coordination practices was identified more than 70 times during the lesson. In the context of the Results section, the students displayed research-oriented coordination practices, which were frequently associated with claims of comprehension difficulty. In the context of the Discussion section, students displayed text-oriented coordination practices, associated with analysis of the text characteristics. We are suggesting that the research-oriented coordination practices and some of the text-oriented ones enabled the emergence of authentic scientific practices and learning by inquiry. Another type of text-oriented coordination practice enabled reflection on scientists’ experimental processes, enabling learning science as inquiry. The enactment model of APL used here allowed for both the emergence of the two dimensions of inquiry learning and the promotion of scientific literacy in the fundamental and derived senses.

Equity-based sustainability and ecocentric management: Creating more ecologically just sport organization practices

Recognizing the shared responsibility all entities with a vested interest in keeping the Earth habitable possess, the authors propose ways in which sport organizations can take action by incorporating ecocentric management principles within their organizational practices and thus become more ecologically just. First, by drawing upon the tenets of the systems thinking paradigm and the four levels of thinking model, the underlying beliefs and values guiding current practices within sport organizations are identified. Next, the authors offer a series of propositions to suggest that by adopting an equity-based perspective, recognizing the interdependent relationships between humans and the natural environment, and acknowledging the manner in which sport organizations hinder the opportunities of the natural environment to thrive, sport organizations can contribute to the health of the planet and all of its inhabitants through their own organizational practices. Additionally, sport organizations can also serve as ecologically just exemplars for organizations in other industries to emulate.     

Three-dimensional conceptual model for service-oriented simulation

In this letter, we propose a novel three-dimensional conceptual model for an emerging service-oriented simulation paradigm. The model can be used as a guideline or an analytic means to find the potential and possible future directions of the current simulation frameworks. In particular, the model inspects the crossover between the disciplines of modeling and simulation, service-orientation, and software/systems engineering. Finally, two specific simulation frameworks are studied as examples.

Mic Check: Occupy Wall Street and the Space of Audition

As used by Occupy Wall Street, the human microphone played a central role in the formation of an auditory space that was animated by the principles of direct democracy that guided the movement. However, the practice also allowed the occupiers to confront and subvert the monopoly on amplified public speech that the government of the City of New York had possessed for nearly eighty years. This paper presents a brief history and analysis of the city's regulation of sound devices, locating the human microphone in a larger struggle over the rights to public speech and assembly.     

Perceptions of parental substance use disorders in cross-system collaboration among child welfare,alcohol and other drugs,and dependency court organizations

Cross-system collaboration among child welfare (CW), alcohol and other drugs (AOD), and court organizations shows promise in addressing the many needs of CW-involved families experiencing parental substance use disorders (SUDs). Research has suggested that differing perceptions of parents with SUDs among staff in these organizations may hinder the collaborative process. Using a sequential explanatory mixed-method approach, this study explored staff perceptions of parental SUDs among CW, AOD, and court organizations. Logistic regression analyses indicated that, compared to CW respondents, AOD respondents were: (a) less likely to believe that parents could provide effective parenting; (b) more likely to believe that abstinence should be a criterion for reunification; (c) more likely to agree that parents should receive jail time as a consequence for noncompliance with court orders; and (d) more likely to believe that parents could succeed in treatment. Thematic analyses of these focal areas identified two core themes (focus on the primary client and mandated time frames for permanency), as well as multiple subthemes, that provided a nuanced understanding of differing perceptions on these matters. Suggestions for the development of anticipatory cross-system training and practices and implications for policy evaluation are discussed.     

Conceptions of Biology and Approaches to Learning of First Year Biology Students: Introducing a technique for tracking changes in learner profiles over time

We surveyed first year students at the start and at the end of their first semester of university biology (n?=?285) as to their approaches to study (surface, deep) and their conceptions of biology (fragmented, cohesive). Hierarchical cluster analysis was used to group students who responded similarly to the survey; this resolved four Learner Profiles based on specific combinations of approach to study and conception of biology. By comparing cluster membership at the start and end of the semester we could assess whether students (1) maintained their incoming approach to study and conception of the discipline of biology, i.e. their ‘Learner Profile’ and (2) whether certain Learner Profiles were more persistent than others. Approximately half the student cohort did not alter their approach to study or conceptions of biology by semester's end. Students in the disengaged profile, i.e. who returned mostly negative responses to survey items, appeared the most resistant to changing their Learner Profile; while the greatest migration occurred towards less than desirable learning strategies (particularly to the disengaged profile). We were able to confirm the significant migration patterns by assessing the heterogeneity of each cluster at the start of semester clusters with respect to the students' approaches and conceptions at the end of semester. Thus we present a process to accurately track Learner Profile changes that may tell us more about how we can enhance students' learning and provide a means by which to gather the empirical data to support decisions relating to curriculum change.
