We investigated differences between field-study classrooms and traditional science classrooms in terms of the learning environment and students’ attitudes to science, as well as the differential effectiveness of field-study classrooms for students differing in sex and English proficiency. A modified version of selected scales from the What Is Happening In this Class? questionnaire was used to assess the learning environment, whereas students’ attitudes were assessed with a shortened version of a scale from the Test of Science Related Attitudes. A sample of 765 grade 5 students from 17 schools responded to the learning environment and attitude scales in terms of both their traditional science classrooms and classrooms at a field-study centre in Florida. Large effect sizes supported the effectiveness of the field-studies classroom in terms of both the learning environment and student attitudes. Relative to the home school science class, the field-study class was considerably more effective for students with limited English proficiency than for native English speakers.  相似文献

Studies have acknowledged children not as climate change victims only, but also as climate change actors. However, only a few have addressed the preparatory stages of children as climate change actors. However, the few studies that addressed these preparatory stages gave attention only to the roles of schools and government agencies without adequate attention to that of parents. This article therefore attempts to discuss the role of eco-parenting in building mitigation and adaptation capacities in children. Relying on the authoritative parenting model, the article avers that eco-parenting can have significant effects on children's ability to protect the environment, mitigate, and adapt to climate change impacts.  相似文献

The free-play behavior of young hearing impaired children in integrated and segregated settings was compared using a multielement baseline design. Two children, aged 3 and 5, were observed using momentary time sampling of their play as they alternated from one setting to the other. Data were collected in ech setting for various categories of play behavior. The categories were derived from the classic play categories of Parten and Smilansky. Results indicate that the children engaged in more socially advanced play in the integrated setting.  相似文献

This article describes a set of computerized tools that support the design and evaluation of competency-based training programs. The training of complex skills such as air traffic control and process control requires a competency-based approach that focuses on the integration and coordination of constituent skills and transfer of learning. At the heart of the training are authentic whole-task practice situations. The instructional design tools are based on van Merriënboer's 4C/ID* methodology (1997). The article describes a training design tool (Core) that supports the analysis and design for competency-based training programs and an evaluation tool (Eval) that supports the subsequent revision of this training design.  相似文献

This study tested preschoolers' ability to provide accurate verbal associations to alcoholic beverage odors and whether this ability was related to parental drinking patterns and motivations. Older preschoolers performed better than younger preschoolers; photographic cues improved performance; children who correctly identified a substance by smell had socially appropriate knowledge of the culturally appropriate users of the substance; children reported liking substances that are used mainly by children and adults, and generally reported disliking substances whose use is legally limited to adults only; children were better at identifying substances they commonly use, but success at recognition of alcoholic beverages was related to heavier parental drinking and use of alcohol for escape reasons. Findings have implications for theories of socialization to drug use and for models of prevention.  相似文献
