How children use input to acquire a lexicon   总被引：2，自引：0，他引：2  

Hoff E  Naigles L 《Child development》2002,73(2):418-433

The contributions of social processes and computational processes to early lexical development were evaluated. A re-analysis and review of previous research cast doubt on the sufficiency of social approaches to word learning. An empirical investigation of the relation of social-pragmatic and data-providing features of input to the productive vocabulary of sixty-three 2-year-old children revealed benefits of data provided in mother-child conversation, but no effects of social aspects of those conversations. The findings further revealed that the properties of data that benefit lexical development in 2-year-olds are quantity, lexical richness, and syntactic complexity. The nature of the computational mechanisms implied by these findings is discussed. An integrated account of the roles of social and computational processes to lexical development is proposed.  相似文献   

Fighting an epidemic: The role of schools in reducing childhood obesity     

Sara A. Pyle  Jill Sharkey  Georgette Yetter  Erika Felix  Michael J. Furlong  W.S. Carlos Poston 《Psychology in the schools》2006,43(3):361-376

Obesity among children and adolescents is a major public health concern affecting the physical and emotional health of youth while increasing their risk of reduced quality and duration of life. Schools and communities have begun to galvanize to address this epidemic and need quality empirical information to guide their policy, programming, and intervention efforts. This article reviews the definition of childhood obesity and the physical, psychosocial, and academic consequences of obesity among youth. The roles of schools and school psychologists in intervening against this overwhelming trend are discussed as well as current empirically based programs. Schools are recommended to take a comprehensive, multifaceted approach to school policies and programs to increase nutrition and physical activity. © 2006 Wiley Periodicals, Inc.

Logistical Factors in Teachers' Motivation     

Erika Daniels 《Clearing house (Menasha, Wis.)》2016,89(2):61-66

Research in education and psychology contributes to an understanding of how educators create contexts for learning that encourage intrinsic motivation and increase academic achievement. In this article, the researcher investigated how teachers themselves define effectiveness and identified what factors influence their motivation, both positively and negatively. The purpose of this study was to explore what factors teachers self-identified as both supporting and hindering their professional motivation. An understanding of what motivates teachers to maintain effectiveness and what contributes to a loss of motivation allows administrators and districts to make professional development, personnel, and curricular decisions that nourish teacher motivation. Data analysis revealed that teacher motivation is influenced by curricular, relational, and logistical factors. Logistical elements that influence teachers' attitudes and effectiveness are discussed here. Findings reveal that the master schedule, organization of time, and the condition of the physical environment play a major role in whether and how teachers are motivated.  相似文献   

The Application of Dynamic Assessment in People Communicating at a Prelinguistic Level: A descriptive review of the literature     

Erika Boers  Marleen J. Janssen  Alexander E. M. G. Minnaert  Wied A. J. J. M. Ruijssenaars 《International Journal of Disability, Development & Education》2013,60(2):119-145

Many people with severe disabilities face difficulties communicating with their communication partners and rely primarily on prelinguistic communication. It is accepted that dynamic assessment can play an important role in improving communication and in measuring a person’s ability to learn new communicative skills. Less is known, however, about the application of dynamic assessment in the case of those who communicate at a prelinguistic level. The present article reviewed dynamic assessment procedures that addressed communication abilities in people communicating at a prelinguistic level and young children who communicate using speech, with the aim of identifying key elements of dynamic assessment for persons communicating at a prelinguistic level. The results indicated the need for the identification of contextual variables that support communicative competence, teaching communication partners new skills, and a procedure that is highly individualised. Further research on the validity and reliability of these dynamic assessments is strongly recommended.  相似文献

Contradictory Views of the Nature of Science Held by a Brazilian Secondary School Physics Teacher: Educational Value of Interviews     

Erika Zimmermann  John K. Gilbert 《Educational Research and Evaluation》2013,19(3):213-234

This paper discusses the bases of a secondary physics teacher’s contradictory conceptions of the nature of science. The data were obtained from a series of four interviews and three months of classroom observation. One of the interviews, a group interview (having as interviewees the subject of this study and four other experienced physics’ teachers), has been shown to be a very powerful way of challenging the teacher’s views, of making him reflect about his ideas, and at the same time of reducing the risk of the interviewer suggesting particular ideas. An analogy to Piaget’s (1929) early methodology supplied a framework with which to categorise the interviewee’s replies. This categorisation has provided information about the bases that underpin the teacher’s different and conflicting views on the nature of science. Résumé Cet article analyse les fondements des conceptions contradictoires d’un professeur de physique de Iycée sur la nature de la science. Les donn?es ont été tirées d’une série de quatre entretiens et de trois mois d’observation en classe. L’un des modes d’entretiens, celui en groupe, au cours duquel les questions ont été posées au professeur sujet de cette étude ainsi qu’à quatre autres professeurs de physique expérimentés, s’est révélé être un moyen très puissant de remettre en question les opinions du professeur, de le faire réfléchir sur ses idées et, en même temps, de réduire le risque lié au fait que celui qui mène l’entretien peut induire des biais. Une analogie avec une des premières méthodologies de Piaget (1929) a permis d’établir une grille qui a servi à classer les réponses des professeurs. Cette classification a fourni des informations qui sont à la base des différences et des contradictions de vue des enseignants sur la nature de la science.  相似文献

Socializing medical students in an era of managed care: The ideological significance of standardized and virtual patients     

Lynn M. Harter Ph.D.  Erika L. Kirby Ph.D. 《Communication Studies》2013,64(1):48-67

Health care practitioners come to understand their professional roles through socialization processes. This project investigates value sets that are constructed through interactions between medical students and two important socializing agents: standardized patients and virtual patients. Through in‐depth interviews with medical students and key administrators at two schools as well as an analysis of rhetorical artifacts about the formal curricula at both schools, we explored the ideological aspects of medical instruction as constituted and reinforced, perhaps subtly, covertly, and even inadvertently, through the pedagogical practices of using standardized and virtual patients. Our results highlight how these medical students perceive standardized and virtual patient interactions as an opportunity to manage uncertainty, and confront a primary tension they will face in enacting their professional rotes—being cost effective and efficient while also treating “patients as people.”  相似文献   

The influence of game location and outcome on behaviour and mood states among professional rugby league players     

Remco Polman  Adam R. Nicholls  Jeannette Cohen  Erika Borkoles 《Journal of sports sciences》2013,31(13):1491-1500

Abstract

In this study, we examined the relationship between home and away matches on mood. In addition, the relationships between game location, game outcome, behavioural factors, and mood were investigated among 12 professional English rugby league players competing in the Super League. Participants completed daily diaries for 27 days. The diary consisted of six analogue scales measuring mood (relaxed – tense, energetic – weary, depressed – elated, tired – alert, anxious – calm, cheerful – miserable) as well as behavioural factors and self-rated performance. There were no significant differences in self-reported mood states leading up to home or away matches except for players feeling more tired when playing away. Significant relationships between mood and behaviours (e.g. sleep and eating) and subjective performance were observed. The outcome of the match was found to influence mood, with a defeat resulting in decreased mood. Our results show that game location did not influence mood and therefore does not provide an explanation for the home advantage.  相似文献
