The use of phonological, orthographic, and contextual information during reading: a comparison of adults who are learning to read and skilled adult readers     

Katherine Binder  Caren Borecki 《Reading and writing》2008,21(8):843-858

The purpose of this study was to assess the role that phonological, orthographic, and contextual sources of information play in a group of adults who were learning to read compared to adult skilled readers. Participants read short paragraphs that contained a correct homophone, an incorrect homophone, or a spelling control. Target words were orthographically similar or dissimilar, and they appeared in context that predicted the target or was neutral with respect to the target. The pattern of data obtained for skilled readers was consistent with past work (Rayner et al., Journal of Experimental Psychology: Learning, Memory and Cognition 24(2), 476–497, 1998). Skilled readers showed no reading time differences between the correct homophone and the incorrect homophone, as long as the two were orthographically similar, but reading times on these words were faster than the spelling control condition. The pattern of data for the adults who were learning to read was different. These readers were actually better at noticing that an incorrect version of the homophone was present. Importantly, we did find consistent significant differences between the incorrect homophone condition and the spelling control condition. This suggests the adults who were learning to read use phonological codes during word recognition, but they do so less efficiently than skilled readers.  相似文献

24 Hours in the Children’s Section: An Observational Study at the Public Library     

Katherine Becker 《Early Childhood Education Journal》2012,40(2):107-114

The purpose of this study was to explore patronage and usage of the children’s section of a public library. Patrons of the children’s section of a public library in a small Northern Arizona city were observed for a total of 24 h over 12 sessions. Analytic induction was used to formulate categories based on field notes made during these observations. An observation of a story time session was also conducted. Data from an interview with a librarian was triangulated with observational data. In terms of patronage, the clear majority of parents/adult caregivers accompanying a child or children to the children’s section were observed to be female and speaking English. In terms of usage, the following three categories of early learning were identified from the data: early literacy learning; learning how to use a library; and other developmentally appropriate learning. Study results offer insight into both the role of females in the intergenerational transmission of literacy and the rich learning young children experience at the library. At a time of library cutbacks and closures across the United States, this study speaks to the continued relevance of the children’s section of the public library in providing free early learning experiences during the pivotal birth to five age range.  相似文献   

Not quite normal: Consequences of violating the assumption of normality in regression mixture models     

Lee Van Horn M  Smith J  Fagan AA  Jaki T  Feaster DJ  Masyn K  Hawkins JD  Howe G 《Structural equation modeling》2012,19(2):227-249

Regression mixture models are a new approach for finding differential effects which have only recently begun to be used in applied research. This approach comes at the cost of the assumption that error terms are normally distributed within classes. The current study uses Monte Carlo simulations to explore the effects of relatively minor violations of this assumption, the use of an ordered polytomous outcome is then examined as an alternative which makes somewhat weaker assumptions, and finally both approaches are demonstrated with an applied example looking at differences in the effects of family management on the highly skewed outcome of drug use. Results show that violating the assumption of normal errors results in systematic bias in both latent class enumeration and parameter estimates. Additional classes which reflect violations of distributional assumptions are found. Under some conditions it is possible to come to conclusions that are consistent with the effects in the population, but when errors are skewed in both classes the results typically no longer reflect even the pattern of effects in the population. The polytomous regression model performs better under all scenarios examined and comes to reasonable results with the highly skewed outcome in the applied example. We recommend that careful evaluation of model sensitivity to distributional assumptions be the norm when conducting regression mixture models.  相似文献   

The role of negative priming in preschoolers' flexible rule use on the dimensional change card sort task     

Müller U  Dick AS  Gela K  Overton WF  Zelazo PD 《Child development》2006,77(2):395-412

Four experiments examined the development of negative priming (NP) in 3-5-year-old children using as a measure of children's executive function (EF) the dimensional change card sort (DCCS) task. In the NP version of the DCCS, the values of the sorting dimension that is relevant during the preswitch phase are removed during the postswitch phase. The experiments showed that the NP effect observed in the DCCS decreased during the preschool years, and they clarified the circumstances in which NP occurs. Taken together, the findings suggest that the development of EF in early childhood consists in part in disinhibiting attention to information that has previously been suppressed.  相似文献   

The Impact of Three-Dimensional Printed Anatomical Models on First-Year Student Engagement in a Block Mode Delivery     

Nicholas Tripodi  Kate Kelly  Maja Husaric  Rebecca Wospil  Michael Fleischmann  Susan Johnston  Katherine Harkin 《Anatomical sciences education》2020,13(6):769-777

Student engagement is known to have several positive effects on learning outcomes and can impact a student's university experience. High levels of engagement in content-heavy subjects can be difficult to attain. Due to a major institutional restructure, the anatomy prosection laboratory time per subject was dramatically reduced. In response, the authors set out to redesign their anatomy units with a focus on engaging the learning activities that would increase time-on-task both within and outside of the classroom. One of these curriculum changes was the implementation of a suite of anatomy learning activities centered on sets of three-dimensional printed upper limb skeleton models. A two-part mixed-method sequential exploratory design was used to evaluate these activities. Part one was a questionnaire that evaluated the students' engagement with and perceptions of the models. Part two involved focus groups interviews, which were an extension of the survey questions in part one. The results of the study indicated that the majority of students found the models to be an engaging resource that helped improve their study habits. As a result, students strongly felt that the use of the models inspired greater academic confidence and overall better performance in their assessments. Overall, the models were an effective way of increasing the engagement and deep learning, and reinforced previous findings from the medical education research. Future research should investigate the effects of these models on student's grades within osteopathy and other allied health courses.  相似文献   

Developmental Trends in Sexual Attraction Among Puerto Rican Early Adolescents in Two Contexts     

Katherine S. Elkington  Milton L. Wainberg  Maria Ramos-Olazagasti  Chen Chen  Ana Ortin  Glorisa J. Canino  Hector R. Bird  Cristiane S. Duarte 《Child development》2020,91(3):1044-1055

Sexual attraction (SA), the earliest stage of sexual orientation, is scarcely studied. This prospective study examined, over 3 years, prevalence, changes in SA, and the role of context, among 946 Puerto Rican youth, aged 11–13 years at initial assessment in the South Bronx (SBx), New York City, and Puerto Rico (PR). Overall, 98.1% of boys and 95.3% of girls reported opposite-sex only SA at some point, whereas 13.8% of girls and 12.0% of boys reported any-same SA. Opposite-sex only SA increased over time, whereas other SAs decreased except for any same-sex SA among SBx girls. Girls in the SBx and younger youth in PR reported more any same-sex SA. Context and culture may play a role in the developmental trajectories of adolescents’ SA.  相似文献   

Using and Selecting Graphic Techniques to Acquire Structural Knowledge     

Katherine L. Beissner  David H. Jonassen  Barbara L. Grabowski 《Performance Improvement Quarterly》1994,7(4):20-38

Structural knowledge, the knowledge of relationships between concepts in a content area, is essential for comprehension and problem solving. Learning structural knowledge can be facilitated through learner-generated two-dimensional diagrams of conceptual relationships. These diagrams include networks, concept maps, pattern notes, semantic maps and graphic organizers. In this paper, we describe the characteristics of graphic techniques and the cognitive processes that learners use to construct the diagrams. We then propose a model that can be used to choose between different graphic techniques based upon the cognitive processes elicited by the techniques and the learning outcomes derived from their use.  相似文献   

Grade retention among students with learning disabilities     

Katherine P. Barnett  Harvey F. Clarizio  Karen A. Payette 《Psychology in the schools》1996,33(4):285-293

This study explored the rates of grade retention among children with undiagnosed learning disabilities. During the 1990–91 school year, data were collected on 344 Michigan students who were referred for special-education evaluation due to learning problems. Of the 201 students determined to possess a learning disability (LD), 71.6% had been retained at least once before they were referred for special-education evaluation. Minority and urban LD students were more apt to be retained before being referred for evaluation. Retained LD students were usually one year older than nonretained LD students at the time of special-education referral. Although retention among LD students did not appear to be related to gender or grade placement, retained LD students generally exhibited lower levels of intelligence and weaker skills in reading comprehension, writing, and math at the time of their referral. © 1996 John Wiley & Sons, Inc.  相似文献   

Publisher–Society partnerships to further image accessibility and global inclusivity in the Humanities and Social Sciences: Comparing top-down and bottom-up approaches     

George Cooper  Katherine Burton  Alejandra Black  Mokheseng Buti  Geraldine Richards  Ginny Herbert  Emma Lockwood  Janet Remmington 《Learned Publishing》2023,36(1):58-67

• Collaboration between publishers and learned society partners can accelerate and amplify DEIA outcomes.
• 97 HSS titles have adopted alt-text publication workflows and this change has been welcomed by journal authors and editors.
• Efforts to promote global inclusivity do not always result in greater membership diversity, retention and growth.
• Top-down, publisher-led DEIA initiatives are effective when they are aligned strategically to pre-existing society initiatives.
• Bottom-up, member-led DEIA initiatives benefit from publisher support to mitigate financial and time-based barriers to active participation.
• To reliably track DEIA outcomes, publishers ought to adopt systematic data collection strategies through initiatives like C4 and the Joint Commitment.
