Models of Language,Models of Childhood in the English National Curriculum

This paper explores the versions of language and of childhood which implicitly underpin the official National Curriculum for English at Key Stages 1 and 2. It considers the politically charged context of debates about ‘grammar’ and ‘standards’ within which a standardised curriculum is imposed, and the assumptions about language, learning and children which are involved in assessing children's talk. Finally, the article draws on an empirical study of the informal talk of six 8‐ and 9‐year‐old children to present some alternative perspectives on children, language and learning.     

An online categorization task to investigate changes in students' interpretations of organic chemistry reactions

In this study, we investigated how students organized their knowledge about organic chemistry reactions in a transformed curriculum, including their choices, abilities, and changes over time. This transformed curriculum focuses on interpreting the underlying mechanistic patterns of chemical reactions and emphasizes the principles of reactivity in organic chemistry. Data from this study were collected at beginning and end of an Organic Chemistry II course using an open and closed online categorization task with a set of organic chemistry reactions. In the open task, participants organized the set of reactions as they chose, giving us insight into how the participants preferred to organize their knowledge. In the closed task, participants were asked to organize the set of reactions in a specific way—by each reaction's governing mechanism—which would provide a measure of the students' ability to categorize the reactions in that way. We investigated the similarities and differences of the open and closed categorizations at each time of administration and analyzed the changes over time. Findings from this study emphasized the efficacy of the transformed curriculum for: (a) promoting a focus on process-oriented features of reactions over static features of a reaction and (b) increasing the students' abilities to categorize a set of reactions according to the mechanism governing the reaction. Findings revealed implications for the transformed curriculum, which addresses key areas for improvements, potential implications for research, and also limitations of the current study. We further describe possible extensions of this study to how the open and closed categorization tasks may be used for research and instruction in other science, technology, engineering, and math disciplines.     

Transformations and Transfer: Preschool Children Understand Abstract Relations and Reason Analogically in a Causal Task

Previous research suggests that preschoolers struggle with understanding abstract relations and with reasoning by analogy. Four experiments find, in contrast, that 3- and 4-year-olds (N = 168) are surprisingly adept at relational and analogical reasoning within a causal context. In earlier studies preschoolers routinely favored images that share thematic or perceptual commonalities with a target image (object matches) over choices that match the target along abstract relations (relational matches). The present studies embed such choice tasks within a cause-and-effect framework. Without causal framing, preschoolers strongly favor object matches, replicating the results of previous studies. But with causal framing, preschoolers succeed at analogical transfer (i.e., choose relational matches). These findings suggest that causal framing facilitates early analogical reasoning.     

Verified: Self-presentation,identity management,and selfhood in the age of big data

ABSTRACT

What new styles of selfhood and self-presentation, forms of social status, and arbiters of “authenticity” are being authorized and propagated in the wake of big data and affective capitalism? How are they functioning, for whom, and to what end? This article takes up these questions via an examination of a sought-after user identity badge, the Twitter verification checkmark, figuring it as both an affective lure that incentivizes specific styles of self-presentation and a disciplinary means through which capitalist logics work to condition and subsume the significance of the millions of forms of self-presentation generated daily. Beneath the promise of democratized access to social status and fame, the business practices of the social platforms in and through which we self-present draw us into privatized strategies of social sorting, identity management, and control. To conclude, the article will posit a new “ideal type” of selfhood for the big data age.     

Goal striving, goal attainment, and well-being: adapting and testing the self-concordance model in sport

Grounded in self-determination theory (Deci & Ryan, 1985) and the self-concordance model (Sheldon & Elliot, 1999), this study examined the motivational processes underlying goal striving in sport as well as the role of perceived coach autonomy support in the goal process. Structural equation modeling with a sample of 210 British athletes showed that autonomous goal motives positively predicted effort, which, in turn, predicted goal attainment. Goal attainment was positively linked to need satisfaction, which, in turn, predicted psychological well-being. Effort and need satisfaction were found to mediate the associations between autonomous motives and goal attainment and between attainment and well-being, respectively. Controlled motives negatively predicted well-being, and coach autonomy support positively predicted both autonomous motives and need satisfaction. Associations of autonomous motives with effort were not reducible to goal difficulty, goal specificity, or goal efficacy. These findings support the self-concordance model as a framework for further research on goal setting in sport.     

Practical considerations when using pedometers to assess physical activity in population studies: lessons from the Burnie Take Heart Study

The aim of this study was to summarize both practical and methodological issues in using pedometers to assess physical activity in a large epidemiologic study. As part of a population-based survey of cardiovascular disease risk factors, physical activity was assessed using pedometers and activity diaries in 775 men and women ages 25-64 years who were residents of Burnie, Tasmania, 1998-99. Common data problems were classified by type. The frequency of each problem and the methods used to identify it are reported along with strategies to correct or prevent each problem type. Pedometer data from 15 (1.9%) participants could not be used due to errors in completing the pedometer protocol. Among 760 participants with usable data, the median number of steps was 9,729 for men and 10,388 for women. Pedometer steps per day were modestly correlated (r = .20, p < .0001) with the duration of pedometer wear, which ranged from 4.50 to 21.75 hr. Adjustment for wear time, however, did not alter observed correlations between pedometer steps and cardiovascular risk factors. The authors conclude that pedometers can be used in large population studies with a relatively low frequency of data errors. However guidelines for consistent data collection and interpretation are needed.     

Migrating facsimiles: When copies disappear from conservation control

A 2014 exhibition of Meriç Algün Ringborg at Moderna Museet, Stockholm, Sweden, exploring identity and belonging involved the making of facsimiles. The installation included a sound work, booklets to be taken, and a book to be read. Exhibition copies were created of personal letters for open display which were not to be touched. Contrary to the artist's wishes, the work was constantly handled. Made for this one installation, the facsimiles transcended the exhibition and were returned with the work to the artist. The paper examines issues of authenticity and control from a conservation standpoint, and details discussions surrounding reproduction in contemporary art museum conservation practice.     

Correlating Spatial Ability With Anatomy Assessment Performance: A Meta-Analysis

Interest in spatial ability has grown over the past few decades following the emergence of correlational evidence associating spatial aptitude with educational performance in the fields of science, technology, engineering, and mathematics. The research field at large and the anatomy education literature on this topic are mixed. In an attempt to generate consensus, a meta-analysis was performed to objectively summarize the effects of spatial ability on anatomy assessment performance across multiple studies and populations. Relevant studies published within the past 50 years (1969–2019) were retrieved from eight databases. Study eligibility screening was followed by a full-text review and data extraction. Use of the Mental Rotations Test (MRT) was required for study inclusion. Out of 2,450 screened records, 15 studies were meta-analyzed. Seventy-three percent of studies (11 of 15) were from the United States and Canada, and the majority (9 of 15) studied professional students. Across 15 studies and 1,245 participants, spatial ability was weakly associated with anatomy performance (r_pooled = 0.240; CI at 95% = 0.09, 0.38; P = 0.002). Performance on spatial and relationship-based assessments (i.e., practical assessments and drawing tasks) was correlated with spatial ability, while performance on assessments utilizing non-spatial multiple-choice items was not correlated with spatial ability. A significant sex difference was also observed, wherein males outperformed females on spatial ability tasks. Given the role of spatial reasoning in learning anatomy, educators are encouraged to consider curriculum delivery modifications and a comprehensive assessment strategy so as not to disadvantage individuals with low spatial ability.
