Language learning takes place in the context of social interactions, yet the mechanisms that render social interactions useful for learning language remain unclear. This study focuses on whether social contingency might support word learning. Toddlers aged 24–30 months (N = 36) were exposed to novel verbs in one of three conditions: live interaction training, socially contingent video training over video chat, and noncontingent video training (yoked video). Results suggest that children only learned novel verbs in socially contingent interactions (live interactions and video chat). This study highlights the importance of social contingency in interactions for language learning and informs the literature on learning through screen media as the first study to examine word learning through video chat technology.  相似文献

Prior research suggests that infants' action production affects their action understanding, but little is known about the aspects of motor experience that render these effects. In Study 1, the relative contributions of self‐produced (= 30) and observational (= 30) action experience on 3‐month‐old infants' action understanding was assessed using a visual habituation paradigm. In Study 2, generalization of training to a new context was examined (= 30). Results revealed a unique effect of active over observational experience. Furthermore, findings suggest that benefits of trained actions do not generalize broadly, at least following brief training.  相似文献

Data from 1,364 children and families who participated in the National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development were analyzed to track the early correlates and later academic outcomes of planning during middle childhood. Maternal education, through its effect on parenting quality when children were 54 months old, predicts their concurrent performance on sustained attention, inhibition, and short‐term verbal memory tests. This performance predicts planning in first grade, which predicts third‐grade reading and mathematics attainment, but not the rate of growth in academic skills from first to fifth grades. This path was also found when the same parenting, cognitive, and academic constructs were measured at later time points.  相似文献

This paper investigates how pupils' growth trajectories in three language domains (reading fluency, spelling, and reading comprehension) are related to their own socioeconomic and ethnic background and to the socioeconomic and ethnic composition of their primary school. Using multilevel piecewise growth curve analysis, the growth trajectories of approximately 5000 pupils from 170 primary schools were estimated. The results indicate that a pupil's socioeconomic and ethnic backgrounds have the largest impact on achievement and growth in reading comprehension and the smallest impact on reading fluency. Furthermore, school ethnic composition—but not socioeconomic composition—was related to pupils' achievement in all three language domains at the first measurement occasion, though none of the types of school composition was related to growth. The research findings therefore imply that to combat the deficits in language proficiency often found in ethnic minority pupils, priority should be given to investments in individual intervention programmes over policy plans to desegregate schools. Moreover, our study identifies the specific points in time during primary school at which intervention programmes are needed the most.  相似文献

This study describes the development and structure of a coding scheme for analysing solutions to well-structured problems in terms of cognitive processes and problem-solving deficiencies for first-year engineering students. A task analysis approach was used to assess students’ problem solutions using the hierarchical structure from a theoretical framework from mathematics research. The coding scheme comprises 54 codes within the categories of knowledge access, knowledge generation, self-management, conceptual errors, mechanical errors, management errors, approach strategies and solution accuracy, and was demonstrated to be both dependable and credible for analysing problems typical of topics in first-year engineering courses. The problem-solving processes were evaluated in terms of time, process elements, errors committed and self-corrected errors. Therefore, problem-solving performance can be analysed in terms of both accuracy and efficiency of processing, pinpointing areas meriting further study from a cognitive perspective, and for documenting processes for research purposes.  相似文献

This study explores the responses of Abby, a young person with autism, to David Macaulay's 1990 picturebook Black and White. Although both picturebook researchers and autism practitioners focus on the importance of encouraging empathetic responses to fictional characters, I build on Louise Collins' argument that Macaulay's work offers an opportunity to develop a different kind of " moral literacy" (2002, p.31). Different ways of practising and understanding perspective‐taking in relation to fiction are considered in light of Abby's responses to Black and White and to fiction more generally. This study, in considering its own weaknesses, also offers a critique of the typical approaches to picturebook research whereby taking the perspective of fictional characters is sometimes seen as indicative of reading competence.  相似文献

Video and photography are often used for delivering content within the anatomical sciences. However, instructors typically produce these resources to provide instructional or procedural information. Although the benefits of learner‐generated content have been explored within educational research, virtually no studies have investigated the use of learner‐generated video and photograph content within anatomy dissection laboratories. This study outlines an activity involving learner‐generated video diaries and learner‐generated photograph assignments produced during anatomy laboratory sessions. The learner‐generated photographs and videos provided instructors with a means of formative assessment and allowed instructors to identify evidence of collaborative behavior in the laboratory. Student questionnaires (n = 21) and interviews (n = 5), as well as in‐class observations, were conducted to examine student perspectives on the laboratory activities. The quantitative and qualitative data were examined using the framework of activity theory to identify contradictions between student expectations of, and engagement with, the activity and the actual experiences of the students. Results indicate that learner‐generated photograph and video content can act as a rich source of data on student learning processes and can be used for formative assessment, for observing collaborative behavior, and as a starting point for class discussions. This study stresses the idea that technology choice for activities must align with instructional goals. This research also highlights the utility of activity theory as a framework for assessing classroom and laboratory activities, demonstrating that this approach can guide the development of laboratory activities.

In the present study we investigated developmental relations among word reading fluency, listening comprehension, and text reading fluency to reading comprehension in a relatively transparent language, Korean. A total of 98 kindergartners and 170 first graders in Korea were assessed on a series of tasks involving listening comprehension, word reading fluency, text reading fluency, and reading comprehension. Results from multigroup structural equation models showed that text reading fluency was a dissociable construct from word reading fluency for both kindergartners and first graders. In addition, a developmental pattern emerged: listening comprehension was not uniquely related to text reading fluency for first graders, but not for kindergartners, over and above word reading fluency. In addition, text reading fluency was uniquely related to reading comprehension for kindergartners, but not for first graders, after accounting for word reading fluency and listening comprehension. For first graders, listening comprehension dominated the relations. There were no differences in the pattern of relations for skilled and less skilled readers in first grade. Results are discussed from a developmental perspective for reading comprehension component skills including text reading fluency.  相似文献

Critical Time     
A politics of time is hidden in the way we approach our objects and areas of inquiry. This includes media, organizations, social movements, technologies, publics, social spaces, identity politics and the environment. Claims upon time are made when we locate power and the various possibilities for social change. In this moment, marked by technological speed up, there is a pervading cultural sense of being short on time. Increasingly time figures within the field and across the disciplines as a problem of better management and control. Time is understood as tension that individuals and institutions wrestle with and must solve. A critical perspective on time should ask a different set of questions. To take a critical perspective is to look beyond individual time and consider time as uncompromisingly tethered, in common while disparate. This paper outlines the possibility of a critical time perspective in communication studies - one where time is understood as multiple, relational, and deeply uneven.  相似文献
