Research Findings: This study examined correlates of parents’ reported school engagement in an ethnically diverse, rural sample (N = 346) of parents and teachers in kindergarten through Grade 2. Of particular interest were role expectations and family–school relationships in American Indian families, who historically have been marginalized by schools. In terms of role expectations, parents and teachers agreed that they should support each other’s roles, parents should have more responsibility than schools for teaching social skills, and families and schools should have shared responsibility for children’s academic success. Teachers had higher expectations than parents for parent engagement, which in turn was greater when parent–teacher communication was more frequent and the school climate was more welcoming. American Indian parents more strongly endorsed a separation of family and school roles and felt less welcomed at school; ethnicity moderated correlates of reported parent engagement. Practice or Policy: These findings have practical promise given that parent–teacher communication, school climate, and role expectations are more easily altered than are structural barriers that also may hinder parents’ involvement in supporting their children’s early education. 相似文献

The anatomy of the pelvis is complex, multilayered, and its three‐dimensional organization is conceptually difficult for students to grasp. The aim of this project was to create an explorable and projectable stereoscopic, three‐dimensional (3D) model of the female pelvis and pelvic contents for anatomical education. The model was created using cryosection images obtained from the Visible Human Project, in conjunction with a general‐purpose three‐dimensional segmentation and surface‐rendering program. Anatomical areas of interest were identified and labeled on consecutive images. Each 2D slice was reassembled, forming a three‐dimensional model. The model includes the pelvic girdle, organs of the pelvic cavity, surrounding musculature, the perineum, neurovascular structures, and the peritoneum. Each structure can be controlled separately (e.g. added, subtracted, made transparent) to reveal organization and/or relationships between structures. The model can be manipulated and/or projected stereoscopically to visualize structures and relationships from different angles with excellent spatial perception. Because of its ease of use and versatility, we expect this model may provide a powerful teaching tool for learning in the classroom or in the laboratory.

Informal environments provide students with unique experiences that allow them to actively participate in activities while promoting a positive attitude toward and an increased interest in science. One way to enhance informal science experiences is through the integration of mobile technologies. This integration is particularly useful in engaging underrepresented students in learning science. Our informal environmental science program engages underrepresented, fifth-grade students in an informal learning environment supplemented with mobile tablet technology (iPads). The purpose of this study was to explore how fifth-grade students interacted with nature using mobile technology during a nature hike series. Participants included 55 fifth-grade students from two low-income schools. We found that students used the mobile technology to explore nature and stay engaged throughout the hike. The iPads were used as references, data collectors, and engagement tools. Students had an intense desire in returning to the site and responded positively toward interacting with nature. Prior research has indicated that students in this age group are likely to lose interest in science and the incorporation of field-friendly technology that engages students with nature, not technology alone, is a useful tool for keeping students interested in science. 相似文献

Analysing the centre of pressure (COP) and centre of gravity (COG) could reveal stabilising strategies used by golfers throughout the golf swing. This study identified and compared golfers’ COP and COG patterns throughout the golf swing in medial–lateral (ML) and anterior–posterior (AP) directions using principal component analysis (PCA) and examined their relationship to clubhead velocity. Three-dimensional marker trajectories were collected using Vicon motion analysis and force plate data from two Kistler force plates for 22 low-handicap golfers during drives. Golfers’ COG and COP were expressed as a percentage distance between their feet. PCA was performed on COG and COP in ML and AP directions. Relationships between principal component (PC) scores were examined using Pearson correlation and regression analysis used to examine the relationship with clubhead velocity. ML COP movements varied in magnitude (PC1), rate of change and timing (PC2 and PC3). The COP and COG PC1 scores were strongly correlated in both directions (ML: r?=?0.90, P?<?.05; AP: r?=?0.81, P?<?.05). Clubhead velocity, explained by three PCs (74%), related to timing and rate of change in COPML near downswing (PC2 and PC3) and timing of COGML late backswing (PC2). The relationship between COPML and COGML PC1 scores identified extremes of COP and COG patterns in golfers and could indicate a golfer’s dynamic balance. Golfers with earlier movement of COP to the front foot (PC2) and rate of change (PC3) patterns in ML COP, prior to the downswing, may be more likely to generate higher clubhead velocity. 相似文献

This article proposes a model for the design of a hybrid VET curriculum across the school-work boundary. VET-curricula are designed on the basis of two main types of learning arrangements, namely, the plan for learning in school and for learning at the workplace. A challenge for curriculum development is creating consistency between different arrangements. Efforts are made to develop VET-curricula that go beyond the school-work distinction. Ideally, a well-designed VET curriculum should be hybrid in nature. It should combine the advantages of school-based and workplace learning arrangements by binding these practices together, without losing the strength of either. To gain insights into the nature of the enactment of an intended and implemented hybrid VET curriculum at the micro level and at the same time contribute to improving educational practice, practice-based research was carried out in the context of educational innovation projects. The results added two insights to the proposed model that conceptualises hybrid VETcurricula, namely, the ‘layeredness’ of a curriculum and a professional artefact to create consistency. This improved model can be the basis for systematic development of other hybrid curricula. Such developments could lead to a broader empirical base to study the effects of hybrid curricula, specifically to determine whether an intentionally designed hybrid curriculum facilitates students to successfully navigate the schoolwork boundary. 相似文献

This paper concerns agricultural entrepreneurs involved in organizing their learning towards developing innovative and learning enterprises. In high-tech sectors, such as Dutch agriculture, this learning and innovative capacity is particularly essential for economic survival. Reviewing the literature we concluded that innovation can be seen as informal learning processes, in which social networks play an important role. Workers learn by sharing knowledge in the working team, and employers learn by creating networks of colleagues and advisors. The results of three research projects teach us that interactive learning and innovation should be analyzed from a perspective of uncertainty. Learning skills for interactive innovation, as part of the entrepreneurial craft, should comprise the capability of selecting impulses and combining newly selected impulses with existing skills and routines. Paradoxically, entrepreneurs need new impulses from weak, unknown networks to be continuously innovative. Innovative learning involves balancing the chaos of uncertainty and the old grooves of experience. Knowing how to escape this paradox forms the core competence of innovative entrepreneurship. In short, we conclude that agricultural entrepreneurs have to develop flexible expertise, based on a complex worldview to meet the demands of innovation in a changing world. Entrepreneurs should particularly be able to detect the irregularities in the world around them and to balance stability and flexibility. 相似文献

Although perishable under many conditions, wooden artifacts from the Neolithic period have been remarkably well preserved in peat bogs and lakes. Indeed, in view of the large number and quality of the finds, the Neolithic Age might equally well be termed the Wood Age. The objects produced were technically highly sophisticated: the properties of different kinds of wood were well known and used to full advantage, and the skill with which they were made suggests that there may have been craftsmen specializing in woodwork. 相似文献
