Schema theory (1975): retrospectives and prospectives     

Newell KM 《Research quarterly for exercise and sport》2003,74(4):383-388

A brief commentary is provided on the theoretical assumptions, scholarly impact and continuing influence of the schema theory of motor learning (Schmidt, 1975). The traditional contrasts of schema theory to the coordinative structure or dynamical systems framework are reemphasized, and limitations of the variability of practice experiments noted. A central problem for theories of motor learning is change over time, the basis on which learning is typically defined. Most theories including schema have, however, undervalued the importance of the time-dependent nature of change in deference to the almost exclusive study of the amount of some averaged change in behavioral outcome. The persistent and transitory change(s) in movement and outcome that are observed in action are reflections of multiple time scales of change in a dynamical system.  相似文献   

Problem analysis: Examining the selection and evaluation of data during problem‐solving consultation     

Markeda L. Newell  Terrance S. Newell 《Psychology in the schools》2011,48(10):943-957

The purpose of this study was to analyze how school psychologists engaged in problem analysis during problem‐solving consultation. Five aspects of the problem analysis process were examined: 1) the types of questions participants asked during problem identification, 2) the types of data participants requested, 3) the frequency of requests for each type of data, 4) the use of multiple methods and sources of data across multiple domains, and 5) the criteria used to interpret the data. Four school psychologists were recruited to each complete three fictional consultation cases within a computer‐simulated environment. A qualitative case study method was used. The results of this study revealed how school psychologists used theory, a multidimensional assessment framework, and self‐referent data to analyze a problem. Implications for future research are discussed. © 2011 Wiley Periodicals, Inc.  相似文献   

Kinematic changes during learning the longswing on high bar     

Williams G  Irwin G  Kerwin DG  Newell KM 《Sports biomechanics / International Society of Biomechanics in Sports》2012,11(1):20-33

The purpose of this study is to provide evidence of technique changes during learning a sports-specific skill, the looped bar longswing (LLS). Thirteen male participants with no previous high bar experience took part in a training study. Kinematic data were collected using a CODA motion analysis system (200 Hz) during eight weekly testing sessions. Analyses focused on the amplitude of swing and the functional phase (FP) actions, defined by the rapid flexion to extension of the shoulders and extension to flexion of the hips as the performer passed through the lower vertical. Three groups were identified based on the number of sessions it took each participant to perform the LLS (G1: most successful, G2: intermediate, and G3: least successful). All participants were able to significantly increase swing amplitude over the training period (p < 0.05). For each participant the hip FP started significantly: later for G1, earlier for G2, and did not change for G3. Extension actions at the shoulders were dissimilar to those reported for elite gymnasts performing the longswing. The FP of the hips provides a mechanism to distinguish between the learners of different skill levels. The study has provided support for a single-subject design when investigating technique changes during learning.  相似文献   

Thriving in the Age of Accelerations: A Brief Look at the Societal Effects of Artificial Intelligence and the Opportunities for Libraries     

Kenning Arlitsch  Bruce Newell 《图书馆管理杂志》2017,57(7):789-798

Fifty years of the compounding effects of Moore's Law have led to enormous advances in computer processing power. Increased network speeds, the availability of big data, and machine learning techniques have accelerated the development of artificial intelligence; this promises to dramatically change many industries, including libraries. This article offers some thoughts on the effects of automation on employment, the social and political fallout, and the threats and opportunities for academic and public libraries.  相似文献   

Teacher Depressive Symptoms and Child Math Achievement in Head Start: The Roles of Family–Teacher Relationships and Approaches to Learning     

Shinyoung Jeon  Lieny Jeon  Sarah Lang  Kaitlyn Newell 《Child development》2021,92(6):2478-2495

This study examined the direct and indirect associations of teachers’ depressive symptoms with children’s math achievement through teachers’ reports of family–teacher relationships and children’s approaches to learning (ATL) in Head Start. This study included 3- and 4-year-old 1,547 children (49% female; 27% White, 24% Black, 41% Hispanic/Latino, and 8% others) who attended Head Start from fall 2014 through spring 2015. Results indicated that teachers’ depressive symptoms were directly associated with lower gains in children’s math skills over a year. In addition, teachers who reported higher depressive symptoms were less likely to report positive family–teacher relationships. This, in turn, resulted in lower gains in children’s ATL and was associated with lower achievement in math skills (r² = .69).  相似文献

Predictive text entry with PAL and children with learning difficulties     

Alan F Newell  Lynda Booth  William Beattie 《British journal of educational technology : journal of the Council for Educational Technology》1991,22(1):23-40

Nine case studies were conducted to evaluate the usefulness of a predictive text entry program within a classroom environment. The program, PAL, was found to be very successful in eight of the cases. For children with poor motor control, the key-saving aspects speeded up text creation. Of even greater significance was the extent to which children with severe spelling problems were helped. They were able to produce much higher quality written work with a substantial reduction in the number of spelling errors. This provided great motivation for the children, and teaching staff commented on their improved confidence and attention span, as well as stimulation of language and vocabulary development. One of the children was on the verge of being classified as a non-reader and, although progress was slow, a significant improvement in the child's work was observed.  相似文献   

Hierarchical Models of Social Competence in Preschool Children: A Multisite,Multinational Study     

Brian E. Vaughn  Nana Shin  Mina Kim  Gabrielle Coppola  Lisa Krzysik  António J. Santos  Inês Peceguina  João R. Daniel  Manuela Veríssimo  Anthon DeVries  Eric Elphick  Xiomara Ballentina  Kelly K. Bost  Wanda Y. Newell  Ellaine B. Miller  J. Blake Snider  Byran Korth 《Child development》2009,80(6):1775-1796

The generality of a multilevel factorial model of social competence (SC) for preschool children was tested in a 5‐group, multinational sample (N = 1,540) using confirmatory factor analysis. The model fits the observed data well, and tests constraining paths for measured variables to their respective first‐order factors across samples also fit well. Equivalence of measurement models was found at sample and sex within‐sample levels but not for age within sample. In 2 groups, teachers’ ratings were examined as correlates of SC indicators. Composites of SC indicators were significantly associated with both positive and negative child attributes from the teachers’ ratings. The findings contribute to understanding of both methodological and substantive issues concerning SC in young children.  相似文献   

A Helping Relationship Experience in Teacher Education,     

Newell T. Gill  Roy King  Ron G. Wilburn 《Journal of Experimental Education》2013,81(2):24-33

The helping relationship experience was explored as a means of insuring greater rapport with children. A sample of 82 junior and senior education students participated for a minimum of two hours/week for approximately eight weeks. Of this group, some were involved with white children; another group with Negro children and a third group served as control. Groups were pre- and post-tested on selected personality variables felt to be necessary for the establishment of good rapport. A complex analysis of variance design was used in analyzing the data. Females and “liberals” scored significantly higher on the MTAI than males or “traditionalists.” Failure to find other evidence of a significant effect on the experimental groups was attributed to insufficient duration and/or intensity of the treatment.  相似文献   

On Masters and Apprentices in Physical Education     

Karl M. Newell 《Quest (Human Kinetics)》2013,65(2):88-96

This paper discusses the impact of the mentoring role of faculty on fostering a quality educational experience for graduate students. Although potentially significant graduate students naturally gravitate to work with significant faculty, it is the mentoring role of the advisor that allows the student's potential to be realized. Clues to the impact of this mentoring role are gleaned from Zuckerman's (1977) analysis of American Nobel Prize laureates. To promote a quality advisor–student relationship, departments need to look beyond the student and considerations of the norms and regulations of entrance and ongoing program criteria. One necessary and very significant precursor will be the presence of quality faculty.  相似文献
