Research Findings: Children's early academic achievement is supported by positive social and behavioral skills, and difficulties with these skills frequently gives way to underachievement. Social and behavioral problems often arise as a product of parent–child interactional patterns and environmental influences. Few studies have examined the role of a salient aspect of children's environments, community locale, in the relationship between parenting practices and child outcomes. Using a large, nationally representative sample, we examined whether preschool parenting practices and children's social-behavioral skills in kindergarten were related to geographic setting (rural vs. city, suburban, and town). Results indicated that rural children experienced greater difficulties with parent-reported externalizing behaviors. Furthermore, rural parents displayed less emotional support than parents in other settings. Preschool parenting behaviors were associated with social skills and behavior problems in kindergarten, as reported by both parents and teachers. Parents' emotional supportiveness was found to account for the relationship between geographic setting and parent-reported children's social skills, such that rural parents who provided less emotional support had children with lower social skills in kindergarten. Practice or Policy: Findings of this research indicate that rural children may face particular risk for behavioral issues and highlight the need for increased behavioral supports in rural communities. Moreover, our results suggest that interventions designed to promote parents' support of children's emotions may have particular utility for rural families. 相似文献

Research Findings: The present study examined the degree to which the association between interactive peer play and academic skills was dependent upon the level of classroom quality for a representative sample of culturally and linguistically diverse urban Head Start children (N = 304 children across 53 classrooms). Peer play interactions within the classroom were assessed by teacher assistants in the fall of the year; observations of the quality of classroom instructional, emotional, and organizational support were conducted in the middle of the year; and norm-referenced direct assessments of literacy, language, and mathematics skills were administered in the spring. Findings from multilevel models indicated that disruptive and disconnected peer play behaviors early in the preschool year were associated with lower literacy and language skills regardless of classroom quality. However, interactive peer play early in the year was associated with higher mathematics outcomes when children were enrolled in classrooms characterized by high instructional support. Practice or Policy: Implications for early childhood research, practice, and policy are discussed. 相似文献

Development of a Short-Form Measure of Science and Technology Self-efficacy Using Rasch Analysis 总被引:1,自引:1,他引:0

Despite an increased focus on science, technology, engineering, and mathematics (STEM) in U.S. schools, today’s students often struggle to maintain adequate performance in these fields compared with students in other countries (Cheek in Thinking constructively about science, technology, and society education. State University of New York, Albany, 1992; Enyedy and Goldberg 2004; Mandinach and Lewis 2006). In addition, despite considerable pressure to promote the placement of students into STEM career fields, U.S. placement is relatively low (Sadler et al. in Sci Educ 96(3):411–427, 2012; Subotnik et al. in Identifying and developing talent in science, technology, engineering, and mathematics (STEM): an agenda for research, policy and practice. International handbook, part XII, pp 1313–1326, 2009). One explanation for the decline of STEM career placement in the U.S. rests with low student affect concerning STEM concepts and related content, especially in terms of self-efficacy. Researchers define self-efficacy as the internal belief that a student can succeed in learning, and that understanding student success lies in students’ externalized actions or behaviors (Bandura in Psychol Rev 84(2):191–215, 1977). Evidence suggests that high self-efficacy in STEM can result in student selection of STEM in later educational endeavors, culminating in STEM career selection (Zeldin et al. in J Res Sci Teach 45(9):1036–1058, 2007). However, other factors such as proficiency play a role as well. The lack of appropriate measures of self-efficacy can greatly affect STEM career selection due to inadequate targeting of this affective trait and loss of opportunity for early intervention by educators. Lack of early intervention decreases selection of STEM courses and careers (Valla and Williams in J Women Minor Sci Eng 18(1), 2012; Lent et al. in J Couns Psychol 38(4), 1991). Therefore, this study developed a short-form measure of self-efficacy to help identify students in need of intervention. 相似文献

This article provides an overview of the characteristics of the flipped classroom, discusses the foundations of this innovative instructional model, and analyzes the possibility of adoption and application to corporate learning platforms. The article assesses whether the flipped classroom is simply a temporary trend in education and learning or has the potential to truly revolutionize instructional design and delivery in the realm of training and development. 相似文献

Evaluation remains one of the biggest challenges for workplace training professionals today. Few organizations have mastered training evaluation, with even fewer moving beyond assessing learner reaction and satisfaction. The introduction of technology‐based distance training, coupled with large initial investments in technologies that are needed to support distance training programs, has further exacerbated evaluation efforts for training organizations. This article looks at the changing environment of training evaluation and the application of evaluation methodology in corporate distance training. 相似文献

This paper describes a study of observed relationships between the design of a preservice elementary mathematics methods course with accompanying field practicum and changes in the extent to which participating prospective teachers identified themselves with the mathematics reform movement after becoming practicing teachers. The curriculum of the course with its embedded field practicum experiences was designed to support prospective teachers in interweaving methods coursework and pedagogical instruction with classroom practice. University and elementary school structures were interwoven by conducting weekly mathematics methods course sessions at a school site followed immediately by related practicum experiences in classrooms in the school. The interweaving of conceptualizations about mathematics teaching and learning was facilitated as the methods instructor provided professional development for classroom teachers simultaneously with the methods course, encouraging the teachers to create “reform-friendly” classroom environments. Survey data from 68 prospective teachers involved in the project were analyzed to identify and describe relationships between course/practicum experiences and the degree to which they as practicing teachers, 1–3 years following the course/practicum, identified with a reform mathematics perspective, as well as to examine factors influencing those relationships. 相似文献

This paper reports on findings derived as part of a two-year project funded by the European Union's Daphne III scheme, involving collaboration between seven partner organisations across six European countries. The project involved an evaluation, using questionnaires and focus groups, of domestic abuse prevention education programmes delivered in schools in the UK, France and Spain. This paper presents the findings from the UK focus group discussions, conducted with young people aged 10–11 years, and 13–14 years to explore their opinions about the intervention delivered in their school. The focus groups revealed the following challenges for service providers in this area: young people can misunderstand issues related to domestic abuse, especially the role of power and control within relationships; there is a tension between educators giving young people free expression to share their opinions and challenging sexism and other prejudices; and boys can become disengaged with gender-based interventions. These issues point towards three key considerations when implementing a domestic abuse prevention education intervention: programme content (the what); the teaching methods used (the how); and whether teachers or external organisations should deliver the programme (the who). 相似文献

Instructors of sexual health courses in rural areas face unique challenges as they are often forced to use school-based prevention curricula field-tested in urban areas. Research has yet to consider what future sex educators’ regional expectations are for their profession and how those expectations might have an impact on the classroom. Drawing from interviews with 26 sex-educators-in-training, we find that future educators tended to expect that rural communities would be less diverse, more conservative, and less informed about sexual health matters, even though research demonstrates that today's rural communities inconsistently align with those perceptions. 相似文献

Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools. 相似文献

A growing body of research documents the positive outcomes of research experiences for undergraduates, including increased persistence in science. Study of undergraduate lab learning experiences has demonstrated that the design of the experience influences the extent to which students report ownership of the project and that project ownership is one of the psychosocial factors involved in student retention in the sciences. To date, methods for measuring project ownership have not been suitable for the collection of larger data sets. The current study aims to rectify this by developing, presenting, and evaluating a new instrument for measuring project ownership. Eighteen scaled items were generated based on prior research and theory related to project ownership and combined with 30 items shown to measure respondents’ emotions about an experience, resulting in the Project Ownership survey (POS). The POS was analyzed to determine its dimensionality, reliability, and validity. The POS had a coefficient alpha of 0.92 and thus has high internal consistency. Known-groups validity was analyzed through the ability of the instrument to differentiate between students who studied in traditional versus research-based laboratory courses. The POS scales as differentiated between the groups and findings paralleled previous results in relation to the characteristics of project ownership. 相似文献
