An important purpose of higher social work education is to guide students to acquire and develop social-communicative competencies.
The purpose of this study was to investigate the role students’ personality characteristics, self-perceived communicative
competence and learning conceptions play in the acquisition and development of social-communicative competencies. We designed
and tested a hypothetical model on the student-related variables – self-perceived communicative competence, learning conceptions
and reported learning activities regarding communication – in relation to performance scores. We were interested in developmental
trends in the above mentioned variables. We also wanted to gain insight into the relationships among the variables. The study
was set up according to a longitudinal, within-subjects design in order to study intra-individual changes. One-hundred and
twenty-three first-year social-work students participated in this study. Many changes were found in students characteristics,
reported deployed learning activities and study results during their first academic year. Except for confidence in “showing
sympathy”, which was already relatively high at the beginning of the study, all scores on aspects of students’ self-perceived
social-communicative competence increased. Assessment scores on comparable communication tests also increased significantly.
Extraversion and emotional stability were the only two personality characteristics, which seemed rather stable. Agreeableness
decreased while autonomy increased continuously during the first academic year. It seemed to be possible to set up a model, which may
serve as a starting point for further research into the development of social-communicative competence. 相似文献

The extraordinary romance and thrilling adventure associated with the tale of wootz steel shows how Indian metallurgists were
the world leaders in antiquity in the manufacture of this legendary high-grade steel. In many ways this material was brought
to global attention by the writings of Cyril Stanley Smith. Modern metallurgy and materials science rest on the foundation
built by the study of this steel during the past three centuries. 相似文献

This article presents an overview of some methods and results from our continuing studies of genetic and environmental influences
on dyslexia, and on individual differences across the normal range that have been conducted over the past 25 years in the
Colorado Learning Disabilities Research Center (CLDRC) and in related projects. CLDRC investigators compare the similarities
of identical twin pairs who share all their genes and fraternal twins who share half their segregating genes to assess the
balance of genetic, shared family environment, and nonshared environment influences on dyslexia and on individual differences
across the normal range. We have learned that among the children we have studied in Colorado, group deficits in reading (dyslexia)
and individual differences in reading across the normal range are primarily due to genetic influences, and these genetic influences
are often shared with some of the same genetic influences on deficits and individual differences in language and ADHD. We
have also learned from our molecular-genetic linkage studies that there are regions on several chromosomes likely to contain
genes that influence dyslexia. Several specific genes within these regions have been tentatively identified through molecular-genetic
association analyses, but much more research is needed to understand the pathways among specific genes, regions of noncoding
DNA that regulate the activity of those genes, the brain, and dyslexia. I conclude with a discussion of our research on individual
differences in early reading development, on the role of early learning constraints in dyslexia, and on how genetic influences
are expressed through their interaction and correlation with the environment. 相似文献

This study utilized data from the Avon Longitudinal Study of Parents and Children (N = 14,860) to examine whether early-life family income (age 0–5) predicted long-term academic achievement (age 16–18) and to investigate the role of executive function (EF) assessed multiple times across age 7–11 in explaining this association. Task-based EF was a significant mediator between early-life family income and later academic achievement in every model. This mediating pathway persisted when adjusting for a comprehensive panel of covariates including verbal IQ, sex, family income at ages 8 and 18, and early-life temperament. Additionally, teacher-rated and parent-rated EF mediated in some models. Overall, these findings suggest that childhood EF may play an important role in perpetuating income-based educational disparities. 相似文献

Infancy (0–3 years) represents a unique time for language learning. Previous research shows that infants' second language (L2) learning advances rapidly in early education centers, through a research‐based method and curriculum delivered by native‐speaking language tutors. Here we test the potential of this method for broad application, through an interactive online tool, SparkLing?, which trains and certifies language tutors to implement the program in infant education centers. Intervention infants (n = 168) from families of predominantly low socioeconomic status (SES) backgrounds in Madrid, Spain, experienced 18 or 36 weeks of L2 (English) exposure, through daily, 45‐min, group sessions led by SparkLing?‐trained tutors and were compared to a matched Current Practice Comparison (CPC) group of peers (n = 72). Intervention children outperformed the CPC group and showed rapid gains in English comprehension and production. SES was not a significant factor in learning. Infants' L2 skills advance quickly using this research‐to‐practice, scalable program for play‐based infant L2 instruction. 相似文献

This article introduces a research study on student model formation and development in introductory mechanics. As a point
of entry, I present a detailed analysis of the Long Decay Model of one-dimensional projectile motion. This model has been
articulated by Galileo (in De Motu) and by contemporary students. Implications for instruction are discussed.
