Improving paddling efficiency through raising sitting height in female white water kayakers

The study compared female white water paddlers over two conditions: with seat raise and with no seat raise. The aim was to determine whether raising the sitting height would improve paddling efficiency. Sitting height of each participant was recorded in order to calculate the seat raise height required and three-dimensional kinematic data was collected for six participants over both conditions. Twelve measures of efficiency were utilised. The efficiency of all participants improved on the seat condition for ≥4 of the measures, with three participants showing improvement for ≥6 of the measures. The stern snaking measure had the highest value of significance (P = 0.1455) and showed an average of 11.98% reduction in movement between no seat and seat conditions. The results indicate that improvements were seen although these were individualistic. Therefore it can be concluded that it is worth experimenting with a seat raise for a female kayaker who is lacking efficiency, noting, however, that improvements might depend on anthropometrics and the seat height selected, and therefore could elicit differing results.     

Self–Efficacy Pathways Between Relational Aggression and Nonsuicidal Self–Injury

The authors recruited college students (N = 648) and investigated relationships among academic and social self–efficacy, relational aggression from parents and peers, and nonsuicidal self–injury (NSSI). Results indicated that both types of self–efficacy were related inversely to NSSI. Academic self–efficacy mediated the relationship between parental emotional abuse and NSSI, whereas social self–efficacy mediated the relationship between peer victimization and NSSI. Clinical implications of these findings for college counselors are discussed.     

A case for cautious optimism? Active citizenship and the Australian civics and citizenship curriculum

In late 2013 a new curriculum for Civics and Citizenship education was published by the Australian Curriculum and Assessment Reporting Authority for use in Australian schools. In line with previous curricular initiatives concerning education for citizenship in Australia a key rationale behind the new subject is the education of “active citizens”. Research evidence over the last 25 years paints a mixed picture regarding the extent to which the translation of policy intent has been successfully implemented within Australian schools. Exploring the new subject of Civics and Citizenship in Australia in the context of previous initiatives and existing research evidence, we explore the contested and complex nature of active citizenship around three key issues – the scope and form of action that constitutes citizenship in one’s communities, how young people themselves conceptualize and experience participation, the potential that active citizenship opportunities are interpreted as being synonymous with the use of active teaching and learning methods. On this basis we argue that the new curriculum provides some optimism for those committed to education for citizenship in Australian schools, but that this optimism needs to be tempered with a degree of caution.     

Sequential progressions in a theory-of-mind scale: longitudinal perspectives

Consecutive retestings of 92 U.S. preschoolers (n=30), Chinese preschoolers (n=31), and deaf children (n=31) examined whether the sequences of development apparent in cross-sectional results with a theory-of-mind scale also appeared in longitudinal assessment. Longitudinal data confirmed that theory-of-mind progressions apparent in cross-sectional scaling data also characterized longitudinal sequences of understanding for individual children. The match between cross-sectional and longitudinal sequences appeared for children who exhibit different progressions across cultures (United States vs. China) and for children with substantial delays (deaf children of hearing parents). Moreover, greater scale distances reflected larger longitudinal age differences.     

Mind what mother says: narrative input and theory of mind in typical children and those on the autism spectrum

In 2 studies mothers read wordless storybooks to their preschool-aged children; narratives were analyzed for mental state language. Children's theory-of-mind understanding (ToM) was concurrently assessed. In Study 1, children's (N=30; M age 3 years 9 months) ToM task performance was significantly correlated with mothers' explanatory, causal, and contrastive talk about cognition, but not with mothers' simple mentions of cognition. In Study 2, the same pattern was found in an older sample of typically developing children (N=24; M age 4 years 7 months), whereas for children on the autism spectrum (N=24; M age 6 years 7.5 months), ToM task performance was uniquely correlated with mothers' explanatory, causal, and contrastive talk about emotions.     

Secondary mathematics cooperating teachers’ perceptions of the purpose of student teaching

This article reports on the results of a survey of 45 secondary mathematics cooperating teachers’ perceptions of the primary purposes of student teaching and their roles in accomplishing those purposes. The most common purposes were interacting with an experienced, practising teacher, having a real classroom experience, and experiencing and learning about classroom management. The most common roles were providing the space for experience, modeling, facilitating reflection, and sharing knowledge. The findings provided insights into the cooperating teachers’ perceptions about both what should be learned through student teaching and how it should be learned. These findings paint a picture of cooperating teachers who do not see themselves as teacher educators—teachers of student teachers. Implications for mathematics teacher educators are discussed.     

Destination,Imagination and the Fires Within: Design Thinking in a Middle School Classroom

The purpose of the Taking Design Thinking to Schools Research Project was to extend the knowledge base that contributes to an improved understanding of the role of design thinking in K‐12 classrooms. The ethnographic qualitative study focused on the implementation of an interdisciplinary design curriculum by a team of university instructors in a public charter school. Three questions framed the study. How did students express their understanding of design thinking classroom activities? How did affective elements impact design thinking in the classroom environment? How is design thinking connected to academic standards and content learning in the classroom?     

AN OPPORTUNITY TO BETTER UNDERSTAND SCHOOLING: THE GROWING PRESENCE OF PISA IN THE AMERICAS*

The Programme for International Student Assessment (PISA) has been developed by the Organisation for Economic Co-operation and Development to provide participating nations with internationally comparative mean literacy scores in reading, mathematics, and science for students nearing the end of compulsory schooling. The number of nations from the Americas that are participating in PISA has been increasing over the past 4 administrations. This 2-part paper (a) outlines the reaction to PISA within the media of both North and South America and (b) presents an Americas-specific example of the ways in which the PISA dataset can be used for more exploratory analysis through the lens of policy and curriculum suggestions, rather than just league table comparisons. We used multilevel modeling of scientific literacy predicted on a number of school-level background variables. Results point to the importance of socioeconomic background of the student as well as the school in predicting scientific literacy across all nations in the study; however, other school-level significant predictors were more nation-specific. Interpretations of these models as well as next steps are discussed.
