The onset of directed reaching demarks the emergence of a qualitatively new skill. In this study we asked how intentional reaching arises from infants' ongoing, intrinsic movement dynamics, and how first reaches become successively adapted to the task. We observed 4 infants weekly in a standard reaching task and identified the week of first arm-extended reach, and the 2 weeks before and after onset. The infants first reached at ages ranging from 12 to 22 weeks, and they used different strategies to get the toy. 2 infants, whose spontaneous movements were large and vigorous, damped down their fast, forceful movements. The 2 quieter infants generated faster and more energetic movements to lift their arms. The infants modulated reaches in task-appropriate ways in the weeks following onset. Reaching emerges when infants can intentionally adjust the force and compliance of the arm, often using muscle coactivation. These results suggest that the infant central nervous system does not contain programs that detail hand trajectory, joint coordination, and muscle activation patterns. Rather, these patterns are the consequences of the natural dynamics of the system and the active exploration of the match between those dynamics and the task.  相似文献   

Developmental changes in the nature of language proficiency and reading fluency paint a more complex view of reading comprehension in ELL and EL1     

Esther Geva  Fataneh Farnia 《Reading and writing》2012,25(8):1819-1845

We examined theoretical issues concerning the development of reading fluency and language proficiency in 390 English Language Learners (ELLs,) and 149 monolingual, English-as-a-first language (EL1) students. The extent to which performance on these constructs in Grade 5 (i.e., concurrent predictors) contributes to reading comprehension in the presence of Grade 2 autoregressors was also addressed. Students were assessed on cognitive, language, word reading, and reading fluency skills in Grades 2 and 5. In Grade 2, regardless of language group, word and text reading fluency formed a single factor, but by Grade 5 word and text reading fluency formed two distinct factors, the latter being more aligned with language comprehension. In both groups a substantial proportion of the variance in Grade 5 reading comprehension was accounted for uniquely by Grade 2 phonological awareness and vocabulary. Grade 5 text reading fluency contributed uniquely in the presence of the autoregressors. By Grade 5 syntactic skills and listening comprehension emerged as additional language proficiency components predicting reading comprehension in ELL but not in EL1. Results suggest that predictors of reading comprehension are similar but not identical in ELL and EL1. The findings point to a more nuanced and dynamic framework for understanding the building blocks that contribute to reading comprehension in ELLs and EL1s in upper elementary school. They underscore the importance of considering constructs such as vocabulary, whose role is stable, and other components of language proficiency and reading fluency whose role becomes pivotal as their nature changes.  相似文献   

Measures of reading comprehension: do they measure different skills for children learning English as a second language?     

Amy Grant  Alexandra Gottardo  Esther Geva 《Reading and writing》2012,25(8):1899-1928

The validity of two measures of English reading comprehension was examined across three different groups of English language learners (ELLs; 64 Portuguese, 66 Spanish and 65 Cantonese). All three groups were achieving within the average range in second grade. An exploratory principal components analysis of reading skills was carried out to determine which skills were related to two commonly used tests of reading comprehension, the Woodcock Language Proficiency Battery??s test of Passage Comprehension (WLPB-PC; Woodcock, 1991) and the Gray Oral Reading Test-4 (GORT-4; Wiederholt & Bryant, 2001). The factor solutions were different for the three language groups but showed many similarities in that the GORT-4 and WLPB-R tests of reading comprehension fell on the same factor within each group. Hierarchical regression analyses examining relationships among vocabulary, decoding and reading comprehension showed that language group membership did not significantly predict performance on either measure of reading comprehension. Differences that arose are likely due to issues with task validity and not ELL status. Limitations and future research are discussed.  相似文献   

Toward modeling reading comprehension and reading fluency in English language learners     

Zohreh Yaghoub Zadeh  Fataneh Farnia  Esther Geva 《Reading and writing》2012,25(1):163-187

This study investigated the adequacy of an expanded simple view of reading (SVR) framework for English language learners (ELLs), using mediation modeling approach. The proposed expanded SVR included reading fluency as an outcome and phonological awareness and naming speed as predictors. To test the fit of the proposed mediation model, longitudinal data from 308 ELLs from different linguistic backgrounds were analyzed using structural equation modeling. We examined the mediating role of Grade 2 word-level reading skills in the association between Grade 1 phonological awareness, naming speed, and listening comprehension and Grade 3 reading comprehension and reading fluency. The results indicated that word-level reading skills fully mediated the association between phonological awareness, reading comprehension and reading fluency. Word-level reading skills partially mediated the association between naming speed and reading fluency. Listening comprehension contributed directly to reading comprehension and reading fluency. It appears that reading development in ELLs is better understood when reading fluency is added to the SVR framework as an outcome and naming speed as a building block of SVR. Theoretical aspects of the mediation model in relation to ELL reading development are also addressed.  相似文献   

Making education world-class: “ThinkGlobalOhio”     

Esther E. Gottlieb 《Prospects》2012,42(3):285-301

For over two decades the State of Ohio has been reforming its education system. This article focuses on the 2006 reform initiatives: a newly elected governor pledged to review and revise its 2002 kindergarten to twelfth grad (K-12) academic content standards and benchmark them to international ??best-in-class?? measures, given Ohio??s need to develop human talent for new industries to replace disappearing jobs in manufacturing. Rather than look at only one other country or state in the US, Ohio compared its standards to those of eight countries and one province; based on this analysis, it rewrote its standards. Ohio has formally adopted the U.S. Common Core Standards and joined the national Partnership for 21st Century Skills, using those learning frameworks to pass legislative amendments for new academic standards and model curriculum. US federal funding from both ??No Child Left Behind?? and ??Race to the Top?? ($400 million) confirms and validates the state??s efforts to build a world-class education system that will make Ohio??s students more competitive in a global economy that demands innovation and a highly skilled workforce.  相似文献   

Self-efficacy, job satisfaction, motivation and commitment: exploring the relationships between indicators of teachers’ professional identity     

Esther T. Canrinus  Michelle Helms-Lorenz  Douwe Beijaard  Jaap Buitink  Adriaan Hofman 《European Journal of Psychology of Education - EJPE》2012,27(1):115-132

This study investigates how relevant indicators of teachers’ sense of their professional identity (job satisfaction, occupational commitment, self-efficacy and change in level of motivation) are related. A model is proposed, tested with structural equation modelling (SEM) and refined using data from 1,214 Dutch teachers working in secondary education. Classroom self-efficacy and relationship satisfaction play a key influencing role in the relationships between the indicators. Using multiple-group SEM, the parameters of the overall model are similar for the novice, experienced and senior teachers in a constrained model. This aspect of similarity across experience groups is in line with findings of previous research on teachers’ professional identity. The present study contributes to the further development of a solid theory on teachers’ professional identity, which has been lacking.  相似文献   

Seniors as Assistants in Freshman Orientation     

Esther Kronovet 《College Teaching》2013,61(1):45-46

The author studied the pedagogy of Socrates looking for teaching techniques that help maintain students' interest in an ongoing discussion. Socrates' use of such strategies as asking probing questions, expanding the discussion into its relationship to other ideas, assuming the role of the devil's advocate, and spending time on group maintenance can be extremely helpful.  相似文献   

LEARNERS’ DEMANDS AND EXPECTATIONS FOR SPACE IN A UNIVERSITY LIBRARY: OUTCOMES FROM A SURVEY AT LOUGHBOROUGH UNIVERSITY1     

Graham Walton 《New Review of Academic Librarianship》2013,19(2):133-149

In this era of e-learning, open-learning and distance learning in the electronic environment, it is interesting to note that library physical space is being given much consideration and thought in higher education institutions. If space is to be provided in an appropriate and welcoming manner, then it is imperative to develop a better understanding of learners’ expectations and needs. In order to provide this intelligence, a major user survey was undertaken at Loughborough University Library in March 2006 of learners’ perceptions of library space. Different kinds of space are provided in the Loughborough University Library, including large group study areas, group study rooms, individual carrels, silence subject floors and personal computer suites. Aspects explored in the survey were how often different library spaces were used as well as the important factors identified when choosing specific space. A further focus was to identify the reasons why library space was used (as well as not used). Further examinations took place of learners’ perceptions of the different space categories. This paper presents the outcomes of the survey (which benefited from over 400 responses). The survey has provided invaluable insight into such issues as noisy versus quiet learning, nature of personal computer access in libraries, importance levels of different factors (such as physical environment and access to library staff) and the role of print (books and journals) in library space. The paper concludes by describing how the survey results have influenced Loughborough University Library future space use. The wider implications for the sector will also be described.  相似文献   

A Comparative Citation Analysis of Web of Science,Scopus, and Google Scholar     

Michael Levine-Clark  Esther L. Gil 《Journal of Business & Finance Librarianship》2013,18(1):32-46

This article presents the results of a comparative study of Web of Science (WoS), Scopus, and Google Scholar (GS) for a set of 15 business and economics journals. Citations from the three sources were analyzed to determine whether one source is better than another, or whether a new database such as Scopus, or a free database such as GS could replace WoS. The authors concluded that scholars might want to use alternative tools collectively to get a more complete picture of the scholarly impact of an article.  相似文献
