Prosodic correlates of stress in babbling: an acoustical study     

Davis BL  MacNeilage PF  Matyear CL  Powell JK 《Child development》2000,71(5):1258-1270

Prelinguistic babbling often seems remarkably speech-like, not because it has recognizable words but because it seems to have adult-like prosody. To quantify this impression, we compared disyllabic sequences from five infants and five adults in terms of the use of frequency, intensity, and duration to mark stress. Significantly larger values for the three acoustic variables were observed on stressed than on unstressed syllables independent of syllable position for both groups. Adults showed the correlates of utterance final syllables--lower f0, lower intensity, and longer duration; infants showed only decrease in intensity. Ratios for stressed to unstressed syllables and participation of the three variables in stress production in individual disyllables were highly similar in both groups. No bias toward the English lexical trochaic stress pattern was observed. We conclude that infants in English environments produce adult-like stress patterns before they produce lexical items, which specify stress. Acoustic and perceptual analyses are used to explore stress marking by prelinguistic infants in an English language environment. Results show that infants employ the three acoustic correlates of stress in individual syllables in a manner largely similar to that of adult speakers, although they do not show second-syllable declination effects or an English language trochaic stress bias.  相似文献   

Taking educational games seriously: using the RETAIN model to design endogenous fantasy into standalone educational games     

Glenda A. Gunter  Robert F. Kenny  Erik H. Vick 《Educational technology research and development : ETR & D》2008,56(5-6):511-537

We are witnessing a mad rush to pour educational content into games in an ad hoc manner in hopes that player/learners are motivated simply because the content is housed inside a game. A failure to base educational game design on well-established learning and instructional theories increases the risk of the game failing to meet its intended educational goals, and yielding students who are entertained but who have not acquired any academic skills or knowledge. Our review of standalone educational games has shown that they are not always based on sound educational principles and theories. We contend that, if academic learning is to take place, a new design paradigm must be developed. This article discusses the RETAIN design and evaluation model for educational games that was developed to aide in the evaluation of how well academic content is endogenously immersed and embedded within the game’s fantasy and story context, promoters transfer of knowledge, and encourages repetitive usage to that content becomes available for use in an automatic way.  相似文献   

Relationship-Focused Child Care Practices: Quality of Care and Child Outcomes for Children in Poverty     

Margaret Tresch Owen  Julia F. Klausli  Ana-Maria Mata-Otero  Margaret O'Brien Caughy 《Early education and development》2008,19(2):302-329

Research Findings: Child care delivery practices promoting continuous, primary caregiver-child relationships (relationship-focused child care) were evaluated for 223 preschool-age children (45% African American, 55% Latino) attending child care centers serving low-income children. Both relationship-focused and non-relationship-focused centers were accredited by the National Association for the Education of Young Children. Children in relationship-focused programs received more sensitive, involved, and affectionate caregiving and were more engaged with their caregivers than children in comparison centers, but some differences were greater for African American children. Outcomes associated with relationship-focused care included greater parent-reported child compliance and closer parent-caregiver relations, but no consistent benefits for cognitive school readiness, receptive language, or child behavior problems were found. Follow-up assessments were completed 1 year later for 119 children who remained in their programs. Social and cognitive outcomes improved over time, but some changes were moderated by child race/ethnicity and center type. Over time, parents reported greater child compliance and caregivers reported better parent-caregiver relationships in relationship-focused programs. Practice or Policy: Some social benefits of continuous, primary caregivers were found, but children's cognitive competencies improved with sustained attendance at these accredited programs regardless of the relationship-focused practices.  相似文献   

Principal Leadership for Technology-enhanced Learning in Science     

Libby F. Gerard  Jane B. Bowyer  Marcia C. Linn 《Journal of Science Education and Technology》2008,17(1):1-18

Reforms such as technology-enhanced instruction require principal leadership. Yet, many principals report that they need help to guide implementation of science and technology reforms. We identify strategies for helping principals provide this leadership. A two-phase design is employed. In the first phase we elicit principals’ varied ideas about the Technology-enhanced Learning in Science (TELS) curriculum materials being implemented by teachers in their schools, and in the second phase we engage principals in a leadership workshop designed based on the ideas they generated. Analysis uses an emergent coding scheme to categorize principals’ ideas, and a knowledge integration framework to capture the development of these ideas. The analysis suggests that principals frame their thinking about the implementation of TELS in terms of: principal leadership, curriculum, educational policy, teacher learning, student outcomes and financial resources. They seek to improve their own knowledge to support this reform. The principals organize their ideas around individual school goals and current political issues. Principals prefer professional development activities that engage them in reviewing curricula and student work with other principals. Based on the analysis, this study offers guidelines for creating learning opportunities that enhance principals’ leadership abilities in technology and science reform.  相似文献   

Science Journals in the Preschool Classroom     

Kimberly Brenneman  Ines F. Louro 《Early Childhood Education Journal》2008,36(2):113-119

We believe that science journals can be used in the preschool classroom as tools for supporting and assessing children’s learning of science- and literacy-relevant content and procedures. To support this argument, we review changes in attitudes about the cognitive competencies of preschoolers and in teaching and learning expectations for early childhood education. We describe practical aspects of using science notebooks with this age group and discuss specific ways that journals support children’s learning. Finally, the role of journals in assessment is discussed.  相似文献

Sex differences in self‐estimation of multiple intelligences among Portuguese adolescents     

Félix Neto  Fátima Ruiz  Adrian Furnham 《High Ability Studies》2008,19(2):189-204

This study investigated the relationship among sex, attitude toward intelligence, and self‐estimation of multiple intelligences for self and parents among Portuguese adolescents in secondary schools. Two hundred and forty‐two adolescents estimated their own and their parents' IQ scores on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body‐kinesthetic, interpersonal, intrapersonal, existential, spiritual, and naturalistic. They also answered six simple questions concerning intelligence and intelligence tests. There were various sex differences in self‐estimated IQ: males rated themselves higher on overall, mathematical, spatial, intrapersonal, spiritual, and naturalistic IQ compared with females. Multiple regressions indicated that verbal, logical, and intrapersonal intelligence were significant predictors for self and parents overall IQ estimations. Factor analysis of the 10, the 8, and the 7 self‐estimates scores did not confirm Gardner's classification of multiple intelligences. Males were more likely to believe in sex differences in intelligence than females. Results are discussed in terms of the growing literature in the self‐estimates of intelligence, as well as limitations of that approach.  相似文献   

TransFormers in knowledge production: building science–practice collaborations     

Anne-Charlotte Hoes  Barbara J. Regeer  Joske F.G. Bunders 《Action Learning: Research and Practice》2008,5(3):207-220

This article places action learning in the context of system innovation, as it studies the potential use of action learning for system change. In order to effect such system change, collaboration between actors from different institutional backgrounds is essential. To gain insight into if and how action learning can be applied for system change, we study three system change projects in Dutch agriculture. We focus specifically on the approaches developed by the project leaders for collaboration between the scientists and the entrepreneurs and analyse how the interaction between these two contributed to the learning process within the project. This article concludes with guiding concepts for action learning for system change in the field of sustainable development of agriculture and beyond.  相似文献   

Following Young Students’ Understanding of Three Phenomena in which Transformations of Matter Occur     

Lena Löfgren  Gustav Helldén 《International Journal of Science and Mathematics Education》2008,6(3):481-504

In order to develop successful teaching approaches to transformations of matter, we need to know more about how young students develop an understanding of these processes. In this longitudinal study, we followed 25 students from 7 to 13 years of age in their reasoning about transformations of matter. The questions addressed included how the students’ understanding of transformations of matter changed and how we can make sense of individual learning pathways. In interviews performed once or twice every year the students described and explained three situations: fading leaves left on the ground, a burning candle, and a glass of water covered with a glass plate on which some mist had formed. When analysing the interviews, we found a common pathway of how the students’ ideas changed over the years in each one of the situations. When analysing individual student’s interviews with Ausubel’s assimilation theory we could discern subordinate, superordinate and combinatorial learning. How these findings can contribute to an improvement of teaching about transformations of matter is discussed.  相似文献   

From teaching from the heart to teaching with a heart: Segmenting filipino college students’ views of their teachers’ caring behavior and their orientations as cared-for individuals     

Allan B. de Guzman  Ramon Kristoffer C. Torres  Millard M. Uy  Joseph Bryan F. Tancioco  Elmore Y. Siy  Jomar R. Hernandez 《Asia Pacific Education Review》2008,9(4):487-502

Caring, as a universal human phenomenon, should permeate elementary, secondary and tertiary level instruction. The practice of teaching, especially at the tertiary level, is not only substantial and procedural but relational as well. To teach with a heart is the essence that makes teaching a form of caring. When teaching is viewed as a form of caring, teachers become relational geniuses in their own right. This study is an attempt to segment Filipino college students’ views (n=1000) of their teachers’ caring behavior and their orientations as cared-for individuals. The identified clusters of teacher roles that indicate caring behavior imply that acts of teaching become acts of caring depending on how the teachers, theefficient cause of education, perform their ordinary tasks in the context ofextraordinariness. Such extraordinariness spells out a big difference in the way teachers practice the so-calledsingle loop caring or caring visibility anddouble- loop caring or caring presence. The former refers to teaching from the heart while the latter pertains to teaching with a heart. Interestingly, the extent to which teachers’ caring behavior is felt and experienced by the students positively shapes their orientations as cared-for individuals.  相似文献
