This paper reports some findings from an investigation of educational practice in ten (formal and informal) education for sustainability (EfS) initiatives, to characterise exemplary practice in school and community education for sustainability, considered crucial to Australia’s future. The study focused on rural/regional Australia, specifically New South Wales sites in the Murray-Darling Basin (crucial to Australian agricultural economy, under substantial environmental threat, undergoing significant social and demographic change). The research used and explored new developments in practice theory, aiming to achieve innovative rich characterisations of individual and extra-individual (cultural, discursive, social, material) aspects of practice. The study aimed to derive implications for theory, policy and practice in relation to sustainability and EfS, practice theory, education, and more specifically education for the professions (including the initial education and continuing professional development of educators).  相似文献

This study examined the effects of an academic music intervention on conceptual understanding of music notation, fraction symbols, fraction size, and equivalency of third graders from a multicultural, mixed socio-economic public school setting. Students (N?=?67) were assigned by class to their general education mathematics program or to receive academic music instruction two times/week, 45?min/session, for 6?weeks. Academic music students used their conceptual understanding of music and fraction concepts to inform their solutions to fraction computation problems. Linear regression and t tests revealed statistically significant differences between experimental and comparison students?? music and fraction concepts, and fraction computation at posttest with large effect sizes. Students who came to instruction with less fraction knowledge responded well to instruction and produced posttest scores similar to their higher achieving peers.  相似文献

Inquiry-based learning (IBL) is promoted as a teaching approach that can enhance student learning outcomes. IBL can be categorised according to scale (e.g. tasks, course/module/paper, degree), mode (structured, guided, open) and framing (information or discovery-oriented). Our research used a survey instrument to determine how student perceptions of learning processes and intended learning outcomes (ILOs) varied in response to courses with different modes and framing of IBL. The survey was completed by 940 students in 15 IBL courses across a range of disciplines and levels. All types of IBL courses were well rated by students for encouraging learning processes and ILOs congruent with a well-designed inquiry experience. Regarding modes of IBL, there was a clear hierarchy from open (most highly rated) to guided and then structured inquiry. For the framing of IBL, courses using discovery-oriented IBL were more highly rated than information-oriented IBL. Overall, the most highly rated course design was open, discovery-oriented IBL, but other types of IBL remained important in terms of developing research and inquiry skills. To determine whether all types of IBL courses are promoting enhanced ILOs compared to more traditionally taught courses, a comparative study should be undertaken.  相似文献

Learning the sounds of letters is an important part of learning a writing system. Most previous studies of this process have examined English, focusing on variations in the phonetic iconicity of letter names as a reason why some letter sounds (such as that of b, where the sound is at the beginning of the letter’s name) are easier to learn than others (such as that of w, where the sound is not in the name). The present study examined Hebrew, where variations in the phonetic iconicity of letter names are minimal. In a study of 391 Israeli children with a mean age of 5 years, 10 months, we used multilevel models to examine the factors that are associated with knowledge of letter sounds. One set of factors involved letter names: Children sometimes attributed to a letter a consonant–vowel sound consisting of the first phonemes of the letter’s name. A second set of factors involved contrast: Children had difficulty when there was relatively little contrast in shape between one letter and others. Frequency was also important, encompassing both child-specific effects, such as a benefit for the first letter of a child’s forename, and effects that held true across children, such as a benefit for the first letters of the alphabet. These factors reflect general properties of human learning.  相似文献

In this study, I used individual growth modeling methods to examine the English word-learning trajectories of adolescent students (N = 278) whose parents speak English at home (n = 210) and those whose parents speak a language other than English (n = 68). Sixth- (n = 130) and seventh-grade (n = 148) students attending an urban middle school took part in the study, with each student contributing up to four occasions of vocabulary-achievement data across three school years. I used the group reading and diagnostic evaluation (GRADE), a 40-item, group-administered assessment to measure vocabulary achievement. Students also provided information about the amount of time they spent reading independently during the summer and during the school year. Principal predictor variables included days between assessments, student home language, student free and reduced lunch status, time spent independent reading, and a dummy variable for the number of summers experienced between testing periods. On average, middle-school students experienced a loss of vocabulary over the summer, however students who spoke a language other than English at home had more pronounced summer setback and steeper learning trajectories, even when controlling for well-known predictors of vocabulary like independent reading and predictors of summer loss like free and reduced lunch status. These findings corroborate research showing low-income students experience summer loss, but suggest that in urban schools serving mostly low-income students, home-language status may be a stronger predictor of summer loss than socio-economic status or reading amount.  相似文献

Guided by a developmental and ecological model, the study employed latent profile analysis to identify a multilevel typology of family involvement and Head Start classroom quality. Using the nationally representative Head Start Family and Child Experiences Survey (FACES 1997; N = 1870), six multilevel latent profiles were estimated, characterized by distinct patterns of parent school involvement, parent home involvement, and classroom quality. The most prevalent profile (47.5% of children within the national sample) reflected low levels of parent home and school involvement practices, but above average classroom quality. Significant differences were found among the six profiles on (a) child, family, classroom, and program demographic characteristics, and (b) children's literacy, language, mathematics, and social skills at the end of children's first Head Start year. The strongest positive associations between profile membership and child outcomes were seen for children in profiles characterized by high levels of parent involvement and above-average levels of Head Start classroom quality, although there were several nuanced distinctions that emerged. Children within the profile characterized by low parent involvement and low classroom quality exhibited lower academic and social outcomes relative to children in higher quality profiles. Implications for early childhood practice, policy, and research are discussed.  相似文献

To examine European American parents’ racial socialization, mothers (n = 84) were videotaped while reading 2 race‐themed books to their 4‐ to 5‐year‐old children and completed surveys concerning their racial attitudes and behaviors. Children completed measures of their racial attitudes and both groups (mothers and preschoolers) predicted the others’ racial attitudes. Results indicated that nearly all mothers adopted “colormute” and “colorblind” approaches to socialization. Furthermore, neither children nor mothers accurately predicted the others’ views. Children’s racial attitudes were unrelated to their mothers’ attitudes but were predicted by their mothers’ cross‐race friendships; those children whose mothers had a higher percentage of non‐European American friends showed lower levels of racial biases than those children whose mothers had a lower percentage of non‐European American friends.  相似文献

Prior research has found that toddlers will form enduring artifact categories after direct exposure to an adult using a novel tool. Four studies explored whether 2‐ (N = 48) and 3‐year‐olds (N = 32) demonstrate this same capacity when learning by eavesdropping. After surreptitiously observing an adult use 1 of 2 artifacts to operate a bell via a monitor, 3‐year‐olds returned to the demonstrated kind of tool as “for” the task and avoided it for an alternative task over 2 days. Two‐year‐olds performed similarly after eavesdropping on someone with more discriminable artifacts via the method of a window rather than a monitor. These results demonstrate that toddlers can acquire enduring artifact categories after less than 40 s of surreptitious observation.  相似文献

A new entry in the testing lexicon is through‐course summative assessment, a system consisting of components administered periodically during the academic year. As defined in the Race to the Top program, these assessments are intended to yield a yearly summative score for accountability purposes. They must provide for both individual and group proficiency estimates and allow for the measurement of growth. They must accommodate students who vary in their patterns of curricular exposure. Because they are meant to provide actionable information to teachers they must be instructionally sensitive, so item‐operating characteristics can be expected to change relative to one another as a function of patterns of curricular exposure. This paper discusses methodology one can draw upon to tackle this ambitious collection of inferences. We consider a modeling framework that consists of an item response theory component and a population component, as in the National Assessment of Educational Progress, and show how performance and growth could be expressed in terms of expected performance on a market basket of tasks. We discuss conditions under which modeling simplifications might be possible and discuss studies that would be needed to fit models, estimate parameters, and evaluate data requirements.  相似文献
