This article addresses the need for changes in current views on adolescent development. It presents observations of adolescent behavior in the online game Dragon Nest that were conducted by specialists from the Crossroads Center for Social and Psychological Adaptation and Adolescent Development, Moscow State University of Psychology and Education, in 2013. These observations helped form theories about age-specific tasks arising in adolescence. The restorative approach was selected as the theoretical basis for this work. This approach represents the practical application of the cultural-historical theory and the activity theory to the provision of social and psychological assistance to adolescents. An analysis of adolescent activity in a game, the structure of communication, and observations of adolescent relationships in online gaming space make it possible to form theories on the role of communication among peers in today’s society in terms of adolescent individuation and development.  相似文献

Latent growth curve models are widely used in the social and behavioral sciences to study complex developmental patterns of change over time. The trajectories of these developmental patterns frequently exhibit distinct segments in the studied variables. Latent growth models with piecewise functions for repeated measurements of variables have become increasingly popular for modeling such developmental trajectories. A major problem with using piecewise models is determining the precise location of the point where the change in the process has occurred and uncovering the related number of segments. The purpose of this paper is to introduce an optimization procedure that can be used to determine both the segments and location of the knots in piecewise linear latent growth models. The procedure is illustrated using empirical data in order to detect the number of segments and change points. The results demonstrate the capabilities of the procedure for fitting latent growth curve models.  相似文献

Duff, Mengoni, Bailey and Snowling (Journal of Research in Reading, 38: 109–123; 2015) evaluated the sensitivity and specificity of the phonics screening check against two reference standards. This report aims to correct a minor data error in the original article and to present further analysis of the data. The methods used are calculation of predictive values of the phonics screening check in addition to sensitivity and specificity, and evaluation of agreement between the reference tests. Predictive values are important indicators of screening test quality. The positive predictive value of the phonics check is low (0.31) when compared with a standardised reading test but high (0.84) when compared with teachers' phonic phases judgements, reflecting poor agreement (kappa = 0.27) between reference tests. Results have implications for practice in terms of choice of reference standard and choice of threshold criterion for children to pass the screening check. Longitudinal data are needed to assess the predictive validity and utility of the check. What is already known about this topic:
  • The importance of phonics in learning to read is widely acknowledged.
  • The phonics screening check was introduced into U.K. schools in 2012 to ensure that all children develop phonic decoding skills.
  • Estimates of the sensitivity and specificity of the phonics screening check, compared with two established ‘reference’ measures, were reported by Duff et al. ( 2015 ).
What this paper adds:
  • We correct a minor error in the report of the original data by Duff et al. ( 2015 ).
  • We draw attention to the importance of including predictive values, alongside sensitivity and specificity, in the evaluation of screening test validity. We also propose an alternative statistic for comparing the two reference measures.
  • We show that applying this further analysis to the data in Duff et al. ( 2015 ) reveals the following: (i) the numbers of incorrect (false positive and false negative) outcomes in the phonics check and (ii) the marked difference in these numbers depending on the choice of reference measure.
Implications for theory, policy or practice:
  • Reports of screening test validity should include positive and negative predictive values.
  • A fundamental consideration for evaluating the validity of the phonics screening check is the choice of reference measure.
  • Longitudinal data are needed to assess the predictive validity and utility of the phonics check.

A comprehensive review of the literature was conducted to identify current practice on teaching science to students with intellectual disability (ID) and/or Autism Spectrum Disorder (ASD) in relation to two review questions—students' science outcomes and students' and teachers' experiences of the interventions. Six databases related to education, psychology, and science were systematically searched. A detailed protocol can be viewed on PROSPERO (registration number: CRD42017057323). Thirty studies were identified that reported on science interventions and 20 on student/teacher experiences of the interventions. The majority of the studies targeted science vocabulary and concepts. Other targets included inquiry skills and comprehension skills. The majority of the interventions used components of systematic instruction (n = 23). Five studies focused on self-directed learning and two on comprehension-based instruction. Students and teachers reported positive experiences of the interventions. The findings suggest that components of systematic instruction in particular might be effective in teaching science content to students with ID and/or ASD. Further research is needed to explore the effectiveness of identified interventions on teaching more complex science skills and with students with severe disabilities. Some limitations related to the search strategy are highlighted.  相似文献

Often, the evidence we observe is consistent with more than one explanation. How do learners discriminate among candidate causes? The current studies examine whether counterfactuals help 5-year olds (N = 120) select between competing hypotheses and compares the effectiveness of these prompts to a related scaffold. In Experiment 1, counterfactuals support evidence evaluation, leading children to privilege and extend the cause that accounted for more data. In Experiment 2, the hypothesis that accounted for the most evidence was pitted against children’s prior beliefs. Children who considered alternative outcomes privileged the hypothesis that accounted for more observations, whereas those who explained relied on prior beliefs. Findings demonstrate that counterfactuals recruit attention to disambiguating evidence and outperform explanation when data contrast with existing beliefs.  相似文献

In this study, we examined the results and interpretations produced from two different IRTree models—one using paths consisting of only dichotomous decisions, and one using paths consisting of both dichotomous and polytomous decisions. We used data from two versions of an impulsivity measure. In the first version, all the response options had labels; in the second version, only the endpoints were labeled. Based on past research, we hypothesized that the endpoints would be selected more frequently in the endpoint-only labeled condition, and the midpoint response option would be selected more frequently in the fully labeled condition. Results from the two models (dichotomous and polytomous) were similar and indicated that our hypotheses were partially supported—specifically, there was no consistent pattern in terms of which condition saw a higher frequency of midpoint response selection. However, our hypotheses regarding extreme responding in the endpoint-only labeling condition were supported.  相似文献

The transition to adult roles usually occurs within a normative age span. By focusing on preadolescence to late adolescence using 2-wave panel data, this research seeks to develop a more informed picture of how "early" exit from the student role and "early" entry into the adult role of parent or spouse reflect factors operating prior to adolescence. The short term consequences of adult role transition on teenage status aspirations, life plans, other psychological orientations, and parental influence are also examined. Even though multiple role transition is frequently observed, only leaving school early appears to be related to preadolescent career decisions and academic performance in high school. The determinants of early transition to the role of parent or spouse do not appear to be socioeconomic origins, parental child rearing techniques or other specific influences, academic ability or performance, or preadolescent aspirations, as has generally been hypothesized in the literature. Research dilemmas and policy implications are discussed.  相似文献
