As part of a longitudinal twin study of literacy and language, we conducted a behaviour‐genetic analysis of orthographic learning, spelling and decoding in Grade 2 children (225 identical and 214 fraternal twin pairs) in the United States and Australia. Each variable showed significant genetic and unique environment influences. Multivariate analyses revealed very high genetic correlations among the variables, indicating that the same genes are involved in their aetiology. These genes are partly independent of those contributing to intelligence. A further analysis indicated that the covariation between decoding and orthographic learning is mediated by shared genes rather than by a direct causal path. The authors argue that a learning parameter, most directly assessed by orthographic learning in this study, underlies all three literacy variables. The results are also discussed in relation to Share's self‐teaching hypothesis, which may require modification. 相似文献

Genetic and Environmental Etiologies of the Longitudinal Relations Between Prereading Skills and Reading 下载免费PDF全文

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post‐first grade (M = 7.4 years), and post‐fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print knowledge, rapid naming, phonological awareness, vocabulary, and verbal memory) were primarily responsible for relations with word reading and spelling. However, relations with post‐fourth‐grade reading comprehension were due to both genetic and shared environmental influences. Genetic and shared environmental influences that were common among the prereading variables covaried with reading and spelling, as did genetic influences unique to verbal memory (only post‐fourth‐grade comprehension), print knowledge, and rapid naming. 相似文献

Given the lack of research on measurement models used to operationalize parental involvement with secondary students, the goal of this research is to examine the measurement properties of the three‐domain conceptualization of parental involvement including school‐based involvement, home‐based involvement, and academic socialization, compared to a more nuanced six domain conceptualization school‐based (1) school/parent communication, (2) attending school activities, home‐based (3) home activities, (4) homework help, academic socialization, (5) parent–child communication about education, and (6) parental aspirations for child's education. When comparing the fit among the models, the six‐factor model had best fit indices and indicated varied correlations among the subdomains. The six‐factor model allowed for more nuanced variations among the subdomains that may be helpful when assessing parental involvement with high school students. 相似文献

This study reports on an intervention involving massage, yoga and relaxation delivered to young children with emotional and behavioural difficulties. Children (n = 126) were invited to participate in the Self‐discovery Programme (SDP) with parental consent. A total of 107 children aged 8–11 years completed the SDP and all measures. Children were allocated to a Control (n = 54) or Intervention (n = 53) group. The results indicate that children in the Intervention group showed improvements in self‐confidence, social confidence, communication and contributions in class. Children in the Intervention group were noted by teachers to use skills learned on the SDP during the school day. 相似文献

AbstractAlthough social acceptance of gender and sexuality diversity is growing in Australian society, in schools, visibility and inclusion of knowledge pertaining to those who are gender- and/or sexuality-diverse, such as lesbians, gay men and transgender people, remain marginalised. This may be due, in part, to a belief that parents are opposed to such content inclusions in their children’s education; yet, virtually no Australian research supports this belief nor have parental perspectives on gender and sexuality diversity inclusion been specifically examined. This paper draws on a broader research study that examined New South Wales parents’ perceptions about the visibility of gender and sexuality diversity and the inclusion or exclusion of related content in school curriculum. It focuses on one particular focus group comprised of only mothers who lived in a specific enclave of Sydney known for its gender and sexuality diversity. The discussion highlights their awareness of gender and sexuality diversity and the dynamics surrounding it; and their perceptions of local school approaches to, and limitations around, gender and sexuality diversity in school curricula, policy and practices, despite potential support for it. 相似文献

Science educators have long been concerned with how formal schooling contributes to learners’ capacities to engage with science after school. This article frames productive engagement as fundamentally about the coordination of claims with evidence, but such coordination requires a number of reasoning capabilities to evaluate the strength of evidence, critique methods, and other factors upon which evidence evaluation rests, evaluating sources and potential biases, and so on. Although the general discourse on education commonly suggests students are bad at such things, we review cognitive development research that demonstrates children display a variety of capabilities, even at early ages, that can be productively built upon by formal science instruction. We use this research to suggest some possibilities for formal schooling to develop children's capacities for evaluating claims within the pursuit of personally meaningful goals. We conclude with observations of useful directions our analysis opens to research. 相似文献

Doctoral dissertations reflect academic specialization in physical education in terms of both graduate programs and authors' future academic orientations. This research project examined specialization as reflected in virtually all of the dissertations written in physical education between 1964 and 1983. Through sequential matching of listings in Dissertation Abstracts Interntioml, Completed Research in Health, Physical Education, and Recreation, and American Doctoral Dissertations, abstracts of 5,344 physical education dissertations were identified and subsequently coded. Selected results included the following: (a) functional effects was the most common academic specialty, (b) the distribution of dissertations among specializations across time changed minimally, (c) the most common academic specialty for DA, EdD, and PED degrees was program development, but the most common specialty for PhD degrees was functional effects, and (d) there was no association between specialties and doctoral program prestige. The results are discussed within the context of the field of physical education in higher education. 相似文献

Presenting narrative text in computer-based instruction (CBI) is more difficult than in print lessons due to limited screen
resolution and display area. The present research aimed at achieving a more compatible match between lesson content and the
attributes of the presentation media. Subjects received either a print or CBI statistics lesson containing low-density (concise)
narrative text, high-density (conventional) text, or the density type they preferred (learner-control). Results showed the
low-density lesson to reduce completion time relative to the high-density version, while yielding equivalent achievement.
Subjects receiving the lesson in the print mode had shorter completion times and higher achievement than their CBI counterparts.
Attitude results showed that CBI was favorably regarded, but perceived as longer and slow-moving than print. Implications
of results for designing instructional material in accord with CBI attributes and learner characteristics are discussed. 相似文献

The purpose of this study was to assess the validity of accelerometers using force plates (i.e., ground reaction force (GRF)) during the performance of different tasks of daily physical activity in children. Thirteen children (10.1 (range 5.4–15.7) years, 3 girls) wore two accelerometers (ActiGraph GT3X+ (ACT), GENEA (GEN)) at the hip that provide raw acceleration signals at 100 Hz. Participants completed different tasks (walking, jogging, running, landings from boxes of different height, rope skipping, dancing) on a force plate. GRF was collected for one step per trial (10 trials) for ambulatory movements and for all landings (10 trials), rope skips and dance procedures. Accelerometer outputs as peak loading (g) per activity were averaged. ANOVA, correlation analyses and Bland–Altman plots were computed to determine validity of accelerometers using GRF. There was a main effect of task with increasing acceleration values in tasks with increasing locomotion speed and landing height (P < 0.001). Data from ACT and GEN correlated with GRF (r = 0.90 and 0.89, respectively) and between each other (r = 0.98), but both accelerometers consistently overestimated GRF. The new generation of accelerometer models that allow raw signal detection are reasonably accurate to measure impact loading of bone in children, although they systematically overestimate GRF. 相似文献
