Phenomenal permanence and the development of predictive tracking in infancy     

Bertenthal BI  Longo MR  Kenny S 《Child development》2007,78(1):350-363

The perceived spatiotemporal continuity of objects depends on the way they appear and disappear as they move in the spatial layout. This study investigated whether infants' predictive tracking of a briefly occluded object is sensitive to the manner by which the object disappears and reappears. Five-, 7-, and 9-month-old infants were shown a ball rolling across a visual scene and briefly disappearing via kinetic occlusion, instantaneous disappearance, implosion, or virtual occlusion. Three different measures converged to show that predictive tracking increased with age and that infants were most likely to anticipate the reappearance of the ball following kinetic occlusion. These results suggest that infants' knowledge of the permanence and nonpermanence of objects is embodied in their predictive tracking.  相似文献

OBJECTIVES: To assess the impact of a voluntary, paraprofessional home visiting program in preventing child maltreatment and reducing the multiple, malleable psychosocial risks for maltreatment for which families had been targeted. METHODS: This collaborative, experimental study focused on 6 Healthy Families Alaska (HFAK) programs; 325 families were enrolled in 2000-2001, randomized to intervention and control groups, and interviewed to measure baseline attributes. Follow-up data were collected when children were 2 years old (85% follow-up rate). Outcomes included maltreatment reports, measures of potential maltreatment and parental risks, for example, poor mental health, substance use, and partner violence. HFAK records were reviewed to measure home visiting services. Home visitors were surveyed to measure perceived effectiveness and training adequacy. RESULTS: Parental risks were common at baseline, and one-sixth of families had a substantiated child protective services report in the child's first 2 years of life. There was no overall program effect on maltreatment reports, and most measures of potential maltreatment. Home visited mothers reported using mild forms of physical discipline less often than control mothers. The groups were similar in their use of more severe forms of physical discipline. There was no program impact on parental risks. There was no impact on outcomes for families with a 'high dose' of home visiting. Home visitors often failed to address parental risks and seldom linked families with community resources. Contradictions in the model compromised effectiveness. CONCLUSIONS: The program did not prevent child maltreatment, nor reduce the parental risks that had made families eligible for service. Research is needed to develop and test strategies to improve the effectiveness of home visiting.  相似文献   

Adolescents’ Friendships,Academic Achievement,and Risk Behaviors: Same-Behavior and Cross-Behavior Selection and Influence Processes     

Mariola C. Gremmen  Christian Berger  Allison M. Ryan  Christian E.G. Steglich  René Veenstra  Jan K. Dijkstra 《Child development》2019,90(2):e192-e211

This study examined to what extent adolescents’ and their friends’ risk behaviors (i.e., delinquency and alcohol use) hinder or promote their academic achievement (grade point average [GPA]), and vice versa. Longitudinal data were used (N = 1,219 seventh- to ninth-grade adolescents; M_age = 13.69). Results showed that risk behaviors negatively affected adolescents’ GPA, whereas GPA protected against engaging in risk behaviors. Moreover, adolescents tended to select friends who have similar behaviors and friends’ behaviors became more similar over time (same-behavior selection and influence). Furthermore, although same-behavior effects seemed to dominate, evidence was found for some cross-behavior selection effects and a tendency in seventh grade for cross-behavior influence effects. Concluding, it is important to investigate the interplay between different behaviors with longitudinal social network analysis.  相似文献   

Elementary teachers’ science subject matter knowledge across the teacher career cycle     

Ryan S. Nixon  Leigh K. Smith  Richard R. Sudweeks 《科学教学研究杂志》2019,56(6):707-731

Although widely touted as important, there is little evidence regarding the influence of teaching experience on elementary teachers' science subject matter knowledge (SMK). To better understand this phenomenon, we administered an assessment of science topics taught in the fifth and sixth grades to 169 preservice teachers, 231 fifth-grade teachers, and 208 sixth-grade teachers. We then compared the mean scores of teachers at different stages in the career cycle using one-way and two-way ANOVA and explored the relationship between SMK scores and years of teaching experience using regression analysis. Findings indicate that (i) being assigned to a specific grade level had an impact on teachers' SMK for topics included in the grade level, (ii) teachers' SMK scores were lower later in their careers for both science topics they had never taught and for science topics they were responsible for teaching, and (iii) results differed for fifth and sixth grades. This study adds to the existing literature through the examination of a large sample of elementary teachers, with teachers of varying years of experience, while focusing on the science topics these teachers are responsible for teaching. The results of this study provide strong evidence that (i) years of experience teaching specific science topics is associated with the development of teachers' knowledge of these topics, and (ii) teaching experience, what teachers do in the context of their everyday practice, can be an effective means of self-directed learning for teachers. There is also evidence that this influence is not uniform across years of teaching experience or science topics taught. These findings raise important implications about future research into the mechanism of SMK development through teaching experience and teacher grade-level assignments.  相似文献   

Teaching primary mathematics with challenging tasks: How should lessons be structured?     

James Russo  Sarah Hopkins 《The Journal of educational research》2019,112(1):98-109

Engaging students in a challenging (cognitively demanding) task and launching a mathematics lesson with a task before instruction are two characteristics of a reform-oriented approach to mathematics instruction often considered together. The authors systematically contrasted teaching with challenging tasks using a task-first lesson structure with that of a discussion-first lesson structure to three composite classes of first- and second-grade students (n = 73). Subsequent assessments of mathematical performance revealed that the discussion-first lesson structure was somewhat more efficacious in improving fluency performance but both structures similarly improved problem-solving performance. The findings suggest there is more than one way of incorporating challenging tasks into mathematics lessons to produce sizeable learning gains.  相似文献   

Engaging Urban Ninth Graders in Math: A Complementary Mixed-Methods Study of Teacher Behavior     

Phillips  Sarah F. 《The Urban Review》2019,51(2):201-230

This mixed-methods study examines engaging teaching at one racially and ethnically diverse public school using the self-system process model of student engagement. As theorized, multilevel analyses of student survey data (N?=?580) reveal that student perceptions of structure, autonomy support, and involvement differentiate highly, moderately, and weakly engaging teachers. Classroom observations (N?=?12) and student interviews (N?=?17) suggest that the behavior of autonomy supportive and involved teachers is friendly, helpful, and emphasizes student agency. Although few racial or ethnic differences are observed, autonomy supportive and involved teacher behavior appears particularly critical to the behavioral engagement of Black and Latinx students. Helpfulness may also moderate stereotype threat. Implications for researchers, practitioners, and policy-makers are discussed.

Habitus as foregrounded history: theorising affect in the social formation of embodied practice     

Sarah Leaney 《British Journal of Sociology of Education》2019,40(2):207-221

This article builds upon a tradition of feminist critical engagements with Bourdieu, developing the concept of ‘foregrounded history’ as a way to conceptualise the temporal and affective in processes of habitus formation. Through analysis of affects ‘produced through the social encounter’ within everyday childhoods on a British council estate, the article explores habitus as histories both embodied and felt in the present. Drawing upon ethnographic research conducted within the interrelated fields of the Primary School and the Community Centre, this article considers processes of distinction, disagreement and resistance in the formation of classed positionings on The Estate.  相似文献   

Understanding the Use of Student-Centered Teaching Methods in Undergraduate Chemistry Courses     

Yoder  Ryan J.  Bobbitt-Zeher  Donna  Sawicki  Vanessa 《Research in Science Education》2019,51(2):845-863

A growing body of research suggests that student-centered teaching methods are associated with positive learning outcomes for undergraduate students. Yet, the extent of their use and factors leading to their adoption in fields, such as chemistry, continue to be under-explored. Utilizing survey data collected during 2015, we begin to fill this gap, first by considering the degree to which faculty and instructors use and plan to use various student-centered teaching methods in their undergraduate chemistry courses. Then, we examine three potential factors that may help us understand variation in (1) use of and (2) intentions to implement student-centered methods: attitudes toward teaching methods; teaching approaches; and institutional characteristics. Importantly, our findings suggest attitudes and individual teaching approaches are significant predictors of the use and intention to implement student-centered methods in the classroom. Perhaps surprisingly, several institutional factors examined (such as class size, percentage of time spent teaching, and type of institution) play no significant role. Given the positive student outcomes associated with various student-centered methods reported in literature, these findings suggest potential avenues for faculty and instructors’ professional development toward further implementation of these methods.

If we build it,will they come? The effect of new athletic facilities on recruiting rankings for power five football and men's basketball programs     

Matt Ryan Huml  N David Pifer  Caitlin Towle  Cheryl R Rode 《Journal of Marketing for HIGHER EDUCATION》2019,29(1):1-18

College athletics is currently in the midst of a building boom in which universities are competing with each other to reach an always-increasing standard of lavish athletic facilities. While these facilities are costing in the tens or hundreds of millions of dollars, little research is examining the return on investment for athletic programs. The purpose of this study was to examine the effect of new athletic facilities on recruiting rankings for Power Five football and men's basketball programs. Data was collected on athletic facilities newly constructed or renovated from 2005 through 2015 at Power Five NCAA Division I programs. Using LSDV fixed effects regression models, results found a lack of significant improvement within football and basketball recruiting rankings following the completion of new athletic facilities, but some significance in the two years before the project was completed. Significant control variables also highlighted the effects that coaching changes can have on recruiting.  相似文献   

Response to Intervention in Middle Schools: Practices and Outcomes     

Sara Prewett  Daryl F. Mellard  Donald D. Deshler  Justin Allen  Ryan Alexander  Amelia Stern 《Learning disabilities research & practice》2012,27(3):136-147

Response to intervention (RTI) is advocated in elementary school as a system‐wide, multitiered model of academic and behavioral interventions. Middle schools have begun adopting RTI models based on these existing elementary models. This investigation into current middle school RTI practices describes technical aspects as well as some of cultural and contextual issues surrounding implementation. The study included multiple data collection procedures including surveys, discussion groups, phone interviews, and site visits. Although many schools reported substantial progress with implementation, they recognized rigorous implementation of RTI posed such on‐going challenges as changes in staffing, curricular realignments, very limited selections of screening and progress monitoring tools aligned with their curriculum, and scheduling of secondary and tertiary level interventions.  相似文献
