Research Fictions: Arts-Informed Narratives That Disrupt the Authority of the Text

In this paper I examine the dilemma faced by reflexive narrative inquirers who write in the first-person “I” while advocating for a postmodern reading of the “self.” This paper asks the question: How can the reflexive educational researcher craft a research narrative that, on the one hand, strives for self-presence, while on the other hand, denies the transparency of language? I discuss current post-structuralist critiques of educational research rhetoric, and extend the critique to narrative research, suggesting that an arts-informed approach to narrative allows researchers to disrupt the authority of their text. I explore the use of a specific fictionalizing technique – the unreliable narrator – to assist readers in critically deciphering reflexive research narratives.     

The role of sweeteners in the diet of young children

The health and nutrition implications of high sugar intake for young children are discussed. Infants and young children prefer foods that taste sweet. Sugar substitutes used in moderation can provide a compromise for child care providers who want to offer nutritious food which young children will eat. This study examined sweetener preferences of young children, including a new sweetener (Sweet One^®). Participants (3–8 years of age) sampled a beverage and plain cottage cheese sweetened with either sugar or Sweet One^® as part of a sensory difference test. They also ranked four vanilla puddings sweetened with sugar and three FDA approved sweeteners. In the difference test, the subjects were able to tell the difference between sugar and Sweet One^® in the beverage, but not in the cottage cheese. There was no consensus among the panelists for a sweetener preference in the rank-order test.     

Knowledge Integration in Science Teaching: Analysing Teachers' Knowledge Development

This paper tests the utility of a new sociocognitive frame for analysing the development of teachers' knowledge – the knowledge integration perspective (Linn, Eylon, & Davis, in press; Linn & Hsi, 2000). In doing so, the paper describes one prospective elementary teacher's developing knowledge and highlights its complexity. The prospective teacher demonstrates relatively well-integrated science subject matter knowledge, but she makes some problematic links to lessons and develops some instructional representations that show where she needs to distinguish between different scientific ideas. She also, however, links science concepts to appropriate real-world experiences, indicating that she has nascent useful pedagogical content knowledge. The paper discusses what teacher educators can learn about their learners from this analysis, argues for the utility of the knowledge integration perspective for conducting similar analyses, provides ideas to help science teacher educators apply the perspective easily as they teach their students, and points to areas ripe for future research.     

Fostering collaborative teaching and learning scholarship through an international writing group initiative

The research presented here explored the experiences of participants in an international collaborative writing group (ICWG) initiative that ran in conjunction with the 2012 International Society for the Scholarship of Teaching and Learning (ISSoTL) conference. The ICWG sought to cultivate collaborative pedagogical scholarship by bringing together a range of international academics to co-author articles on teaching and learning topics of shared interest. Data were collected via online surveys at the beginning and end of the initiative and interim focus groups/interviews. In addition to suggesting that the ICWG is an effective means of fostering collaborative writing, the results point to a number of factors that might also influence collaboration in other contexts: modes of collaboration, opportunities for social dialogue, developing a shared vision and voice, and leadership. Implications and applications of the findings, as well as areas of further research, are discussed.     

Social interaction and the use of analogy: An analysis of preservice teachers' talk during physics inquiry lessons

Analogies have been argued to be central in the process of establishing conceptual growth, making overt connections and carryover into an intended cognitive domain, and providing a generative venue for developing conceptual understanding inherent in constructivist learning. However, students' specific uses of analogies for constructing arguments are not well understood. Specifically, the results of preservice teachers' knowledge gains are not widely studied. Although we would hope that engaging preservice science teachers in exemplary lessons would assist them in using and generating analogies more expertly, it is not clear whether or how such curricula would affect their learning or teaching. This study presents an existence proof of how preservice science teachers used analogies embedded in their course materials Physics by Inquiry. This fine‐grained analysis of small group discourse revealed three distinct roles of analogies including the development of: (a) cognitive process skills, (b) scientific conceptual understanding, and (c) social contexts for problem solving. Results suggest that preservice teachers tend to overgeneralize the analogies inserted by curriculum materials, map irrelevant features of analogies into collaborative problem solving, and generate personal analogies, which counter scientific concept development. Although the authors agree with the importance of collaborative problem solving and the insertion of analogies for preservice teachers' conceptual development, we believe much more needs to be understood before teachers can be expected to construct and sustain effective learning environments that rely on using analogies expertly. Implications for teacher preparation are also discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 443–463, 2003     

Pathways to understanding mind: construct validity and predictive validity of maternal mind-mindedness

The construct validity of maternal mind-mindedness (MM) was investigated in the context of its relations with children's later understanding of mind. MM measures were obtained from infant-mother (N = 52) interactions at 6 months, and from maternal interviews at 48 months. Children's understanding of mind was assessed using theory of mind (ToM) tasks at 45 and 48 months, and a stream of consciousness (SoC) task at 55 months. One of the early MM measures--mothers' appropriate mind-related comments--was a positive independent predictor of: (a) MM at 48 months, and (b) ToM and SoC performance at 45 to 55 months. Path analyses suggested direct links between mothers' use of appropriate mind-related comments and children's later understanding of mind.     

A review of the research of Ference Marton and the Goteborg Group: A phenomenological research perspective on learning

This article reviews the work of Ference Marton and his group of researchers at the University of Goteborg in Sweden. It describes and explains research into: what students learn; how students approach studying; the relationship between approach to study and learning outcomes; what students understand learning to consist of; and whether it is possible to manipulate students' approach to studying in order to influence the learning outcomes. This review is intended to build up an overall picture of learning as seen from a phenomenological research perspective.     

Characteristics of School Districts That Participate in Rigorous National Educational Evaluations

Given increasing interest in evidence-based policy, there is growing attention to how well the results from rigorous program evaluations may inform policy decisions. However, little attention has been paid to documenting the characteristics of schools or districts that participate in rigorous educational evaluations, and how they compare to potential target populations for the interventions that were evaluated. Utilizing a list of the actual districts that participated in 11 large-scale rigorous educational evaluations, we compare those districts to several different target populations of districts that could potentially be affected by policy decisions regarding the interventions under study. We find that school districts that participated in the 11 rigorous educational evaluations differ from the interventions' target populations in several ways, including size, student performance on state assessments, and location (urban/rural). These findings raise questions about whether, as currently implemented, the results from rigorous impact studies in education are likely to generalize to the larger set of school districts—and thus schools and students—of potential interest to policymakers, and how we can improve our study designs to retain strong internal validity while also enhancing external validity.

Intrapersonal Emotion Regulation Processes Influence What Children Remember About Their Emotional Experiences

Little work has tested how emotion regulation (ER) processes influence children's memory for negative experiences. We investigated how two intrapersonal ER processes (affect-biased attention and changes in negative feelings) predicted children's (N = 184, 93 girls, ages 3–11) memory. Recall of a sad or scary film was tested after a delay. The way discrete emotional information was remembered varied with ER and children's age. Older children with greater affect-biased attention or less reduction of fear demonstrated privileged memory for central information from the scary film. Older children with greater affect-biased attention but greater reductions in sadness recalled more from the sad film overall. Findings suggest ER processes should be considered when examining children's memory for negative emotional information.
