Across the great divide: bridging the gap between understanding of toddlers' and older children's thinking   总被引：2，自引：0，他引：2

Research on very young children's cognitive development differs greatly from research on cognitive development in older children. The differences include the questions that are asked, the methods that are used to address them, the measures that are employed to provide relevant evidence, and the level of detail at which children's knowledge is represented. The research approaches are so different that they create an impression that infants' and toddlers' thinking differs qualitatively from that of preschoolers and older children. This impression, however, may reflect differences in research approaches rather than differences in children's thinking. In the present study, we attempted to bridge this gap by applying to toddlers a type of process analysis that has proved fruitful in studies of older children. Overlapping waves theory, trial-by-trial strategy assessments, and microgenetic methods were used to analyze 1.5- and 2.5-year-olds' problem solving and learning. The results demonstrated that changes in toddlers' strategies could be assessed reliably on a trial-by-trial basis, that the changes followed the basic form predicted by the overlapping waves model, and that analyses of toddlers' strategies could tell us a great deal about both qualitative and quantitative aspects of their learning. A componential analysis of learning that previously had been applied to older children also proved useful for understanding toddlers' learning. The analysis specified that cognitive change frequently involves five components: acquisition of new strategies; strengthening of the strategies in their original context; improved mapping of strategies onto novel problems; increasingly refined choices among variants of the strategies; and increasingly skillful execution of the strategies. Independent measures of these components indicated that strategic development in toddlers involves improvements in all five components. Analyses of individual differences in learning showed that the effects of distal variables, such as age and sex, could be partially explained in terms of their influence on mastery of the components, but that the distal variables exercised additional direct effects as well. The process of learning in toddlers closely resembled that of older children in other ways as well. Like older children, toddlers use multiple strategies over the course of learning; their choices among strategies are quite adaptive from early on; their choices become progressively more adaptive as they gain experience with the task; they switch strategies not only from trial to trial but within a single trial; their transfer of learning from one problem to the next is primarily influenced by structural relations between problems but also is influenced by superficial features; they show utilization deficiencies early in learning that they gradually overcome; and they show individual differences in learning that fall into a few qualitatively distinct categories. Perhaps most striking, the 1.5- and 2.5-year-olds emerged as active learners, who continued to work out the lessons of previous instruction in the absence of further instruction. That is, they integrated the lessons of their own problem-solving efforts with the previous instruction in ways that magnified the initial effects of the instruction. Overall, the findings indicated that the gap can be bridged; that theories, methods, measures, and representations of knowledge typically used with older children can improve our understanding of toddlers' problem solving and learning as well.  相似文献   

Faculty roles and role preferences in ten fields of professional study     

Joan S. Stark  Malcolm A. Lowther  Bonnie M. K. Hagerty 《Research in higher education》1986,25(1):3-30

Teaching faculty in ten entry-level professional fields reported varying amounts of time devoted to teaching, research, consulting, and professional practice but did not differ in time devoted to administration. The faculty member's own role view was most closely related to time use, but for time spent in teaching and research, faculty age and institutional type (but not gender) were also significant predictors. Even after several general demographic characteristics and environmental variables that potentially differentiate professional from discipline-based faculty are taken into account, different professional fields may be characterized by group climates which influence or reinforce certain faculty roles.  相似文献   

Exploiting aspectual features and connecting words for summarization-inspired temporal-relation extraction   总被引：2，自引：0，他引：2  

Bonnie J. Dorr  Terry Gaasterland   《Information processing & management》2007,43(6):1681

This paper presents a model that incorporates contemporary theories of tense and aspect and develops a new framework for extracting temporal relations between two sentence-internal events, given their tense, aspect, and a temporal connecting word relating the two events. A linguistic constraint on event combination has been implemented to detect incorrect parser analyses and potentially apply syntactic reanalysis or semantic reinterpretation—in preparation for subsequent processing for multi-document summarization. An important contribution of this work is the extension of two different existing theoretical frameworks—Hornstein’s 1990 theory of tense analysis and Allen’s 1984 theory on event ordering—and the combination of both into a unified system for representing and constraining combinations of different event types (points, closed intervals, and open-ended intervals). We show that our theoretical results have been verified in a large-scale corpus analysis. The framework is designed to inform a temporally motivated sentence-ordering module in an implemented multi-document summarization system.  相似文献   

Multi-candidate reduction: Sentence compression as a tool for document summarization tasks   总被引：2，自引：0，他引：2  

David Zajic  Bonnie J. Dorr  Jimmy Lin  Richard Schwartz   《Information processing & management》2007,43(6):1549

This article examines the application of two single-document sentence compression techniques to the problem of multi-document summarization—a “parse-and-trim” approach and a statistical noisy-channel approach. We introduce the multi-candidate reduction (MCR) framework for multi-document summarization, in which many compressed candidates are generated for each source sentence. These candidates are then selected for inclusion in the final summary based on a combination of static and dynamic features. Evaluations demonstrate that sentence compression is a valuable component of a larger multi-document summarization framework.  相似文献   

Science Supports Education: The Behavioral Research Base for Psychology's Top 20 Principles for Enhancing Teaching and Learning     

Joan M. Lucariello  Bonnie K. Nastasi  Eric M. Anderman  Carol Dwyer  Heather Ormiston  Russell Skiba 《Mind, Brain, and Education》2016,10(1):55-67

Psychological science has much to contribute to preK‐12 education because substantial psychological research exists on the processes of learning, teaching, motivation, classroom management, social interaction, communication, and assessment. This article details the psychological science that led to the identification, by the American Psychological Association's Coalition for Psychology in Schools and Education, of the “Top 20 Principles from Psychology for PreK‐12 Teaching and Learning.” Also noted are the major implications for educational practice that follow from the principles.  相似文献   

Trajectories of perinatal depressive symptoms in the context of the COVID-19 pandemic     

Hanna C. Gustafsson  Anna S. Young  Olivia Doyle  Bonnie J. Nagel  Kristen Mackiewicz Seghete  Joel T. Nigg  Elinor L. Sullivan  Alice M. Graham 《Child development》2021,92(5):e749-e763

This study sought to advance understanding of the potential long-term consequences of the COVID-19 pandemic for child development by characterizing trajectories of maternal perinatal depression, a common and significant risk factor for adverse child outcomes. Data came from 393 women (86% White, 8% Latina; mean age = 33.51 years) recruited during pregnancy (n = 247; mean gestational age = 22.94 weeks) or during the first year postpartum (n = 146; mean child age = 4.50 months; 55% female). Rates of depression appear elevated, relative to published reports and to a pre-pandemic comparison group (N = 155). This study also provides evidence for subgroups of individuals who differ in their depressive symptom trajectories over the perinatal period. Subgroup membership was related to differences in maternal social support, but not to child birth outcomes.  相似文献   

Parents’ participation on school councils analysed through Arnstein’s ladder of participation     

Bonnie Stelmach 《School Leadership & Management》2016,36(3):271-291

Although parent school councils are the archetypal arrangement for engaging parents in school improvement planning, their effectiveness is negligible when it comes to building parents’ capacity for and confidence in educational decision-making. Using Arnstein’s ladder of citizen participation, this qualitative case study investigated the nature and degree of parents’ participation on six school community councils (SCCs) in Saskatchewan, Canada. Focus groups and interviews with SCC parent members, and school and district leaders were the chief data sources. In most schools, the SCC structure did not dislodge time-honoured barriers that restricted parents’ influence on extracurricular issues. A conceptual examination of participation affords a process-oriented understanding of parent involvement that complements the existing focus on the factors that impact school council effectiveness as an outcome.  相似文献

Child maltreatment prevalence and mental disorders outcomes among American Indian women in primary care     

Duran B  Malcoe LH  Sanders M  Waitzkin H  Skipper B  Yager J 《Child abuse & neglect》2004,28(2):131-145

OBJECTIVE: To examine (1) the prevalence, types, and severity of child abuse and neglect (CAN) and (2) the relationship between CAN and lifetime psychiatric disorders among American Indian women using primary care services. METHODS: A cross-sectional study was conducted among 234 American Indian women, age 18-45 who presented for outpatient ambulatory services at a community-based Indian Health Service Hospital in Albuquerque, New Mexico. Dependent measures included mood, substance abuse, and anxiety disorders as well as posttraumatic stress disorder (PTSD) as measured by the Composite International Diagnostic Interview. CAN was assessed using the Childhood Trauma Questionnaire. RESULTS: Approximately three-quarters of respondents (76.5%; 95% CI = 70.4, 81.7) reported some type of childhood abuse or neglect; over 40% reported exposure to severe maltreatment. Severity of child maltreatment was associated in a dose response manner with lifetime diagnosis of mental disorders. After adjusting for social and demographic correlates, severe child maltreatment was strongly associated with lifetime PTSD (prevalence ratio [PR] 3.9; 95% CI = 1.9, 8.0); and was moderately associated with lifetime substance use disorders (PR = 2.3; 95% CI = 1.6, 3.3); mood disorders (PR = 2.1; 95% CI 1.4, 3.2); and with two or more disorders (PR = 2.3; 95% CI = 1.6, 3.4). CONCLUSION: CAN was common in our sample of American Indian women in primary care and was positively associated with lifetime psychiatric disorders outcomes. Screening for CAN and psychiatric disorders would enhance the treatment of patients seeking primary care services. Primary prevention of child maltreatment might reduce the high prevalence of mental disorders among American Indian women.  相似文献
