Writing creatively in a museum: tracing lines through persons,art objects and texts

Creative writing is often thought of as an individual and solitary pursuit. This is partly owing to Romantic (and still popular) notions of creativity as residing in highly gifted individuals, but also to the widely held belief that writing is a lonely rather than a social activity. The research presented in this paper provides a unique insight into the creative process by tracing the way one poem is produced by a member of a creative writing class based on a major urban art gallery. Based on a 5‐year ethnographic study of this class, it employs interview material, field notes, photographs and creative writing as data. Using theories from both the “anthropology of writing” (Barton and Papen, 2010 ; Latour and Woolgar, 1986 ) and the “anthropology of creativity” (Ingold, 2007 ; Hallam and Ingold, 2007 ), I argue that creative writing is a relational and temporal process involving complex and multiple claims for agency. I also go on to show that when the text moves from a private to a public context, these multiple agencies are encompassed and erased under the umbrella of individual authorship.     

Incorporating Uncertainty Into Parallel Analysis for Choosing the Number of Factors via Bayesian Methods

A number of psychometricians have suggested that parallel analysis (PA) tends to yield more accurate results in determining the number of factors in comparison with other statistical methods. Nevertheless, all too often PA can suggest an incorrect number of factors, particularly in statistically unfavorable conditions (e.g., small sample sizes and low factor loadings). Because of this, researchers have recommended using multiple methods to make judgments about the number of factors to extract. Implicit in this recommendation is that, when the number of factors is chosen based on PA, uncertainty nevertheless exists. We propose a Bayesian parallel analysis (B-PA) method to incorporate the uncertainty with decisions about the number of factors. B-PA yields a probability distribution for the various possible numbers of factors. We implement and compare B-PA with a frequentist approach, revised parallel analysis (R-PA), in the contexts of real and simulated data. Results show that B-PA provides relevant information regarding the uncertainty in determining the number of factors, particularly under conditions with small sample sizes, low factor loadings, and less distinguishable factors. Even if the indicated number of factors with the highest probability is incorrect, B-PA can show a sizable probability of retaining the correct number of factors. Interestingly, when the mode of the distribution of the probabilities associated with different numbers of factors was treated as the number of factors to retain, B-PA was somewhat more accurate than R-PA in a majority of the conditions.     

A Case Study Exploring the Identity of an In-Service Elementary Science Teacher: a Language Teacher First

Teachers are central to providing high-quality science learning experiences called for in recent reform efforts, as their understanding of science impacts both what they teach and how they teach it. Yet, most elementary teachers do not enter the profession with a particular interest in science or expertise in science teaching. Research also indicates elementary schools present unique barriers that may inhibit science teaching. This case study utilizes the framework of identity to explore how one elementary classroom teacher’s understandings of herself as a science specialist were shaped by the bilingual elementary school context as she planned for and provided reform-based science instruction. Utilizing Gee’s (2000) sociocultural framework, identity was defined as consisting of four interrelated dimensions that served as analytic frames for examining how this teacher understood her new role through social positioning within her school. Findings describe the ways in which this teacher’s identity as a science teacher was influenced by the school context. The case study reveals two important implications for teacher identity. First, collaboration for science teaching is essential for elementary teachers to change their practice. It can be challenging for teachers to form an identity as a science teacher in isolation. In addition, elementary teachers new to science teaching negotiate their emerging science practice with their prior experiences and the school context. For example, in the context of a bilingual school, this teacher adapted the reform-based science curriculum to better meet the unique linguistic needs of her students.

     

Situated Simulation-Based Learning Environment to Improve Proportional Reasoning in Nursing Students

Proportional reasoning is the basis for most medication calculation processes and is fundamental for high-quality care and patient safety. We designed a simulated Medication Mathematics (siMMath) environment to support proportional reasoning in transitioning via concreteness fading between two mediators. The first mediator is simulated nursing tools of medication preparation. The second is a ratio-table setup which is used as a goal representation, which enables one to spatially hold in place different quantities in their relative proportion. We conducted a two-part study with nursing students. Part 1 was a quasi-experimental pretest–intervention–posttest design assessing the effectiveness of learning, by evaluating four categories of medical calculation questionnaire items (solid medications, unit conversion, concentrations, infusion rates). We used the Noelting proportional reasoning test to evaluate the generalizability and abstraction of proportional reasoning. Part 1 included an experimental group (n = 96) learning with siMMath, and a comparison group (n = 73) learning with an equation-based lecture approach. Part 2 employed a case study design to characterize the learning process. The experimental group’s learning gains were significantly higher than the comparison group’s for the two most challenging categories of the medication calculation problems questionnaire, namely concentrations and infusion rates. Furthermore, the experimental group’s learning gains were significantly higher than the comparison group’s for formal operational reasoning on the Noelting test. Students who used a ratio-table setup scored significantly higher on the Noelting posttest questionnaire. Nursing students who learned with the siMMath environment overcame difficulties in proportional reasoning to the highest levels and extended this understanding to other contexts.     

Endurance of Undergraduate Attitudes Toward Older Adults

This cross-sectional study assessed undergraduate attitudes toward older adults and attitude endurance 3 to 18 months after aging coursework. Survey respondents included 349 students who took an aging elective and 430 comparison students. Aging-elective students indicated more positive attitudes than comparison students. Attitudes did not vary across 3 groups staggered by time elapsed from completing the course until testing (3 to 18 months). 4 variables accounted for the variance in attitudes toward elders at a statistically significant level: majoring in biology, having frequent or occasional contact with unrelated older adults, taking an aging course, and post-course knowledge of aging.     

The ‘Strange Alteration’ of Hamlet: Comic Books,Adaptation and Constructions of Adolescent literacy

This article examines two comic book adaptations of Shakespeare’s Hamlet produced for teenage readers and used in school classrooms. It seeks to understand the ways in which particular kinds of literacy are being implied and constructed through the textual practice of multimodal adaptation. It presents a close reading of sections of the texts and places them within the framework of multimodal theory and adaptation studies. The paper is part of a larger study of comic book adaptations of Shakespeare’s plays based on a series of semi-structured interviews with the producers (publishers, artists, textual editors) involved in the adaptation process. The data are analysed in order to raise questions concerning the assumptions about literacy inherent in educational texts, and to outline the importance of further qualitative research in the area.     

Does STES‐Oriented Science Education Promote 10th‐Grade Students’ Decision‐Making Capability?

Today’s society is continuously coping with sustainability‐related complex issues in the Science‐Technology‐Environment‐Society (STES) interfaces. In those contexts, the need and relevance of the development of students’ higher‐order cognitive skills (HOCS) such as question‐asking, critical‐thinking, problem‐solving and decision‐making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish “base lines” for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision‐making capability, science‐oriented (n = 142) and non‐science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre‐post development/change of students’ decision‐making capabilities via STES‐oriented HOCS‐promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision‐making questionnaire was used for obtaining a research‐based response to the guiding research questions. Our findings suggest that a long‐term persistent application of purposed decision‐making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high‐school students’ decision‐making ability. The need for science teachers’ involvement in the development of their students’ HOCS capabilities is thus apparent.
