Social interaction,relationships, and the development of causal discourse and conflict management

Links between the development of social understanding and social processes are considered, in the context of data on the development of causal reasoning and argument in conflict, drawn from a longitudinal study of 50 children observed in conversation with their mothers, siblings, and friends at 33 and 47 months of age. Children showed powers of causal reasoning before they were 3 years, capabilities that showed rapid developmental change; their interest in cause was particularly focussed on psychological causality and social action. The contexts of disputes were especially important. Differences were found in children’s arguments with their mothers, siblings, and friends, with more ‘other-oriented’ reasoning shown with friends. It is argued that the data support Vygotskyan ideas on the significance of social interaction in developmental advance, that the pragmatics of what children and their partners are trying to do must be taken into account in considering what children may be learning in interactions, and that ‘social competence’ should not be treated as an individual within-child trait, but that we should move towards a ‘relationships’ approach to the development of social understanding.     

Self Reflections of Undergraduate Students on Using Web-Supported Counterintuitive Science Demonstrations

Analysis of self-reflections of undergraduate education students in a project involving web-supported counterintuitive science demonstrations is reported in this paper. Participating students (N?=?19) taught science with counterintuitive demonstrations in local elementary school classrooms and used web-based resources accessed via wireless USB adapters. Student reflections to seven questions were analyzed qualitatively using four components of reflection (meeting objectives/perception of learning, dynamics of pedagogy, special needs accommodations, improving teaching) deriving 27 initial data categories and 12 emergent themes. Overall the undergraduates reported meeting objectives, engaging students in pedagogically relevant learning tasks including, providing accommodations to students with special needs, and gaining practice and insight to improve their own teaching. Additional research is needed to arrive at generalizable findings concerning teaching with web-supported counterintuitive science demonstrations in elementary classrooms.     

Somersaulting techniques used in high-scoring and low-scoring Roche vaults performed by male Olympic gymnasts

The aim of this study was to compare the somersaulting techniques used in the 16 highest-scoring and 16 lowest-scoring Roche vaults. Our hypothesis was that the gymnasts performing the highest-scoring Roche vaults would demonstrate a better technique than those performing the lowest-scoring Roche vaults while on the horse (pushing off the horse more effectively), somersaulting (executing most of the required somersaults higher in flight), and landing (showing a greater control). A 16-mm motion picture camera, operating at 100 Hz, recorded the vaults during the official competition. The two-dimensional direct linear transformation was used for spatial reconstruction. The results of t-tests (P < 0.05) indicated that, compared with the low-scoring gymnasts, the high-scoring gymnasts had: (1) greater height of body centre of mass and a more fully extended body position at the horse take-off; (2) greater height of body centre of mass at the peak of post-flight, knee release, and touchdown on the mat; (3) greater horizontal and vertical displacements of body centre of mass, greater somersaulting rotation, and longer time from the knee release to mat touchdown; and (d) markedly smaller landing point deductions. In conclusion, a successful Roche vault is likely when the focus is on: (a) leaving the horse with a large vertical velocity in an extended body position to achieve a high trajectory of centre of mass by first extending the legs, then immediately pushing off the horse vigorously, using the muscles of the upper extremity; (b) grasping the knees immediately after the take-off from the horse, achieving the tightly tucked body position early during the ascent to the peak, and completing two-thirds of the required somersaults at a great height; (c) releasing the knees and extending the body above the top level of the horse; and (d) contacting the mat with a high body centre of mass position.     

Using Art Media During Prewriting: Helping Students with Dysgraphia Manage Idea Generation Before Encoding Text

Many students struggle with writing skills. This study focuses on three students (second and fourth grades) who were classified with a learning disability by their school. These children had writing goals and objectives (i.e., characteristics of having dysgraphia) included in their Individual Education Plan. In a single case design format, each student was taught the Ask, Reflect, Text (ART) mnemonic strategy to help improve story content and quality. The components of ART include students Ask themselves a series of seven questions; the students then Reflect on their answers and illustrate their story-content responses with art media (e.g., paints, colored markers, play dough); and from this prewrite illustration, students generate their Text. All participants improved greatly in story content. They also improved in story quality but to a lesser extent.
