Gaze Behavior of Gymnastics Judges: Where Do Experienced Judges and Gymnasts Look While Judging?

Gymnastics judges and former gymnasts have been shown to be quite accurate in detecting errors and accurately judging performance. Purpose: The purpose of the current study was to examine if this superior judging performance is reflected in judges’ gaze behavior. Method: Thirty-five judges were asked to judge 21 gymnasts who performed a skill on the vault in a video-based test. Classifying 1 sample on 2 different criteria, judging performance and gaze behavior were compared between judges with a higher license level and judges with a lower license level and between judges who were able to perform the skill (specific motor experience [SME]) and those who were not. Results: The results revealed better judging performance among judges with a higher license level compared with judges with a lower license level and more fixations on the gymnast during the whole skill and the landing phase, specifically on the head and arms of the gymnast. Specific motor experience did not result in any differences in judging performance; however, judges with SME showed similar gaze patterns to those of judges with a high license level, with 1 difference in their increased focus on the gymnasts’ feet. Conclusion: Superior judging performance seems to be reflected in a specific gaze behavior. This gaze behavior appears to partly stem from judges’ own sensorimotor experiences for this skill and reflects the gymnasts’ perspective onto the skill.     

Oxygen concentration and mobility in conserved archaeological wood

Probes for measuring oxygen concentration were installed inside large samples of conserved wood from archaeological shipwrecks to record oxygen profiles as a function of depth under the wood surface. The concentration of oxygen was lower inside the wood than outside indicating that the supply of oxygen is limited and that oxygen is consumed within the material. This was confirmed by oxygen consumption rates averaging 1.3 ± 0.42?µg O₂/g wood/day. The diffusion properties were estimated by placing the wood samples in a nitrogen atmosphere and measuring nitrogen breakthrough time to the oxygen probes at different depths. A high level of variation was observed between the breakthrough times measured at different depths of the samples. This indicated that the access of oxygen is irregular, possibly due to wood heterogeneity and uneven distribution of conservation agent. By recording oxygen concentrations inside archaeological wood under stable environmental conditions, it was shown that oxygen concentration profiles are almost constant over a time span of seven years. This indicates that oxygen consumption, and thus oxidative degradation, is constant for an extended period of time. It also shows that the oxygen concentration inside conserved archaeological wood is a steady state value controlled by the local balance between oxygen supply and oxygen consumption.     

Parental Age and Offspring Childhood Mental Health: A Multi-Cohort,Population-Based Investigation

To examine the contributions of maternal and paternal age on offspring externalizing and internalizing problems, this study analyzed problem behaviors at age 10–12 years from four Dutch population-based cohorts (N = 32,892) by a multiple informant design. Bayesian evidence synthesis was used to combine results across cohorts with 50% of the data analyzed for discovery and 50% for confirmation. There was evidence of a robust negative linear relation between parental age and externalizing problems as reported by parents. In teacher-reports, this relation was largely explained by parental socio-economic status. Parental age had limited to no association with internalizing problems. Thus, in this large population-based study, either a beneficial or no effect of advanced parenthood on child problem behavior was observed.     

Are statisticians cold‐blooded bosses? a new perspective on the ‘old’ concept of statistical population

Spurred by recent writings regarding statistical pragmatism, we propose a simple, practical approach to introducing students to a new style of statistical thinking that models nature through the lens of data‐generating processes, not populations.     

The teacher work sample: A tool for scaffolding and assessing preservice teachers' early field experiences

Abstract

This article describes adapting teacher work sample methodology from the student teaching level to a 4‐week, 25‐hour field experience occurring relatively early in a teacher education program. The goals of the project were twofold: (a) to examine whether an adapted version of the teacher work sample would promote planning and reflection in preservice teachers, and (b) to explore the potential of an adapted teacher work sample as an assessment tool. Adaptations to the original, such as emphasizing formative over summative assessment, are briefly described. Survey and focus group data from a pilot combined with survey data from a semester of full implementation with 270 teacher candidates indicate the teacher work sample is useful for promoting reflection and an understanding of student assessment. The advantages of the teacher work sample are maximized when teacher candidates are engaged in whole class instruction.     

Intersecting Domains of Assessment Knowledge: School Typologies Based on Interviews with Secondary Teachers

This study used qualitative interviewing with teachers at three high schools to answer research questions about teachers' assessment knowledge, school-specific assessment cultures, and teachers' perceptions of the assessment literacy of other key stakeholders. Data analysis revealed shared knowledge and practices across schools—use of formative assessment to guide instructional decision making; reliance on collaborative processes as the basis for cultivating school-wide assessment practices; and the belief among teachers that students, parents, and school administrators often hold naive views about the relative primacy of summative over formative assessment. Data analysis also identified distinctive features of the assessment culture at each of the schools.     

Developmental consequences of early parenting experiences: self-recognition and self-regulation in three cultural communities

This study relates parenting of 3-month-old children to children's self-recognition and self-regulation at 18 to 20 months. As hypothesized, observational data revealed differences in the sociocultural orientations of the 3 cultural samples' parenting styles and in toddlers' development of self-recognition and self-regulation. Children of Cameroonian Nso farmers who experience a proximal parenting style develop self-regulation earlier, children of Greek urban middle-class families who experience a distal parenting style develop self-recognition earlier, and children of Costa Rican middle-class families who experience aspects of both distal and proximal parenting styles fall between the other 2 groups on both self-regulation and self-recognition. Results are discussed with respect to their implications for culturally informed developmental pathways.     

Wie die Türken in unsere Köpfe kamen. Das Türkei-Bild in der deutschen Pädagogik zwischen 1820 und 1930

The article reconstructs the image of Turkey and the Turks that German education portrayed between 1820 and 1930. The analysis is based on educational periodicals and reference works from the historical eras of the German Confederation, the German Empire and the First World War, tracing the way old stereotypes persisted and new stereotypes arose. The study especially focuses on the opinions of German educationalists about schools in Turkey, Turkish women, Islam, the question of whether Turkey was part of Europe, and last not least on whether Ottoman educational policies were appropriate. Closely following the historical sources, the article shows how the opinions of German educationists changed according to the shift of Germany’s geopolitical interests, how their outlook went hand in hand with the views of the general press, and how they gradually came to a professional self-concept that contrasted ‘their’ educational system with what they believed was a ‘backward’ system in Turkey. At the same time they began to develop an interest in doing professional work in Turkey. The article can also be regarded as a contribution to the history of educational thinking in Germany in the course of the nineteenth century.
