Programs to promote children's early development are based on a set of assumptions, explicit or implicit, about intended outcomes and how the program will effect change. The “theories of change” were examined in ten home-based programs in the Early Head Start Research and Evaluation Project (EHSREP), using data collected through multiple interviews with program staff. All home-based programs indicated that parenting outcomes were among their highest three priorities, while only 4 of 10 programs said that child outcomes were in their top priorities. The pattern of outcome differences between randomly-assigned program and control group participants reflected the programs’ theories of change in several ways. Early Head Start home-based programs showed positive impacts on 9 of 9 parenting outcomes, including parental supportiveness, home language and learning supports, emotional responsiveness, and family conflict when children were 24 months of age. Significant program impacts on child cognitive skills (Bayley MDI scores) and social behavior (observed child engagement of parent during play) were found when children were 36 months of age. Mediation analyses showed that the 54% of the program impact on 36-month child cognitive scores was mediated by 24-month program impacts on parental supportiveness, language and learning support, emotional responsiveness, and family conflict, and 47% of the program impact on 36-month child engagement of parent was mediated by 24-month impacts on parental supportiveness, language and cognitive stimulation, and emotional responsiveness. Results from mediation analyses were consistent with these home-based programs’ theories of change, supporting the efficacy of focusing on parent change as a mechanism for child outcomes in home visiting programs.  相似文献

Gender discrimination in academia was examined by means of a climate survey at a research university, which asked faculty about their experiences, observations, and satisfaction within their work environment. Overall, responses indicated that most faculty felt satisfied with key aspects of their environment, and many felt they had experienced, or observed, little or no discrimination. However, among those who did report personally experiencing discrimination, there were consistent gender differences across all areas. Specifically, women were more likely than men to report that they had experienced exclusion by colleagues, inappropriate sexual attention from colleagues or administrators, demeaning or intimidating behaviors from students, colleagues, or administrators, and unfair treatment in processes of hiring, reappointment, promotion, or tenure.  相似文献

OBJECTIVE: The primary aim of the current study was to examine the contributions of sexual abuse, physical abuse, family cohesion, and conflict in predicting the psychological functioning of adolescents. Additional analyses were conducted to determine whether adolescent victims of child sexual abuse and physical abuse perceive their family environments as more conflictual and less cohesive than nonabused adolescents. METHOD: Participants were 131 male and female adolescents, ages 16 years to 18 years, receiving services at a residential vocational training program. Participants completed well established psychological assessment tools to assess abuse history, family environment characteristics, and current adjustment. RESULTS: Physically abused adolescent females perceived their family environments as more conflictual and less cohesive than females without physical abuse, and sexually abused females perceived their family environments as more conflictual and less cohesive than females without sexual abuse. Physically abused adolescent males reported more conflict than males without physical abuse, but did not differ with regard to cohesion. Adolescent males with and without a sexual abuse history did not differ on the family dimensions. Multiple regression analyses revealed that both conflict and cohesion, in addition to a history of sexual and physical abuse, predicted depression and distress. Separate analyses by gender revealed these variables differentially impact adjustment in male and female adolescents. Results of a power analysis indicated sufficient power to detect these differences. CONCLUSIONS: Findings indicate that in addition to child sexual abuse and physical abuse, family conflict and cohesion are risk factors for the development of psychological distress and depression in adolescence. Implications for treatment and directions for future research are discussed.  相似文献

This preliminary study examined the effect of a caring-based versus a traditionally-focused physical activity intervention on underserved adolescents’ perceptions of the caring climate, the motivational climate, empathetic concern, enjoyment, and future anticipated participation. Multiethnic youth (N = 353) aged 9 to 17 involved in two National Youth Sports Program (NYSP) sites participated in the study. The Caring Group (n = 90) participated in a program infused with themes of caring while the Traditional Group (n = 263) followed prototypical NYSP training, practices, and procedures. Self report assessments were gathered after 5 weeks in either setting. After accounting for demographic differences findings revealed that the Caring Group perceived significantly higher levels of a caring climate, empathetic concern, future expected participation, and lower levels of perceptions of an ego-involving motivational climate. The relevance of these findings with respect to the optimal development of youth is discussed.

This study was designed to investigate the potential effects of kinesio tape on the flexion-relaxation phenomenon, trunk postural control and trunk position sense when applied for a short period (30 min) to the low back of healthy female participants. Twenty-four participants were assigned to one of two groups: kinesio tape applied in either the recommended stretched or non-stretched (control) manner over the low back. Tests were performed at three time points (pre-tape, with tape, post-tape) to assess low-back muscle flexion-relaxation, position sense during active trunk repositioning and trunk postural control during seated balance. Results demonstrated that wearing kinesio tape did not affect the angle at which the erector spinae muscles became silent during trunk flexion (flexion-relaxation). Trunk repositioning error increased when wearing kinesio tape in both the stretched and non-stretched manner, and this increased error persisted after the tape was removed. Seated balance control improved when wearing kinesio tape in both the stretched and non-stretched manner, and these improvements persisted after the tape was removed. In conclusion, these findings do not support the general suggestions that short-term use of kinesio tape on the low-back region alter low-back muscle activation and enhance tasks related to proprioception, at least under these taping conditions in a group of healthy females.  相似文献

This study examined the extent to which fifth-grade students participate in online argumentation and the argument patterns they produced about the inquiry-based investigations completed using the Science Writing Heuristic approach in their science classes. One hundred twenty-nine students from five classes of two teachers in a Midwestern public school completed two inquiry-based investigation units, one per semester, followed by asynchronous online discussions using the Moodle forum. Among the 129 students, 107 students produced 739 notes in the plant investigation online discussion and 111 students produced 686 notes in the human health investigation online discussion. Results indicate that students were actively engaged in the online discussions about inquiry investigations with comments being focused on providing more evidence and backing for claims and negotiating evidence in both investigations. The students also engaged in challenging and querying the test procedures and reference sources as the basis for evidence. Implications are discussed for science teaching and learning and further study on argument-based inquiry in online environments.  相似文献

Emotions play a significant part in students’ learning experiences within complex educational environments. However, the impact of emotional experiences on effective learning is not straightforward. For example, being confused during learning may be perceived as an adverse event. There is, however, considerable research evidence suggesting that confusion can also be a productive aspect of a student's learning processes. Despite this, research also suggests that when confusion is persistent it can become harmful, promoting learner frustration or boredom. Key challenges for the design of interactive digital learning environments (IDLEs) are to detect and assess students’ emotions and to tailor the environment accordingly. In this paper we examine, from a review of the literature, the implications of learners’ confusion that can occur in IDLEs. Strategies for managing students’ confusion will then be discussed and examples of features enhancing learning in IDLEs will be suggested.  相似文献

The home learning environment (HLE) that children experience early on is highly predictive of their later academic competencies; however, the bulk of this work is operationalized from mothers’ perspectives. This study investigates the HLE provided by both mothers and fathers to their preschoolers (n = 767), with consideration for how parents’ practices relate to one another as well as how these practices predict children’s early academic outcomes. Using an SEM framework, results indicate that while, overall, mothers provide HLE activities more frequently than fathers do, both mothers (β = .18, p < .05) and fathers (β = .22, p < .05) make unique contributions to their preschooler’s early academic skills, but only for families where mother has less than a bachelor’s degree. For families where mother has a bachelor’s degree or higher, the effect of father’s HLE practices is not a significant predictor of children’s academics when considering mother’s HLE. For all families, fathers are providing a variety of HLE activities to their young children; and, although these may occur less frequently than mothers’ practices, they are particularly important for the academic development of children whose mothers have less than a bachelor’s degree. Practical implications are discussed.  相似文献

This article presents a content analysis of three computer‐mediated communication (CMC) networks used for political discussion during the 1992 Presidential election campaign. Data indicate that the main use of computer networks in the campaign was to assert personal opinions about the candidates, issues, and the election. Other uses were talking about one's own life and experiences, telling others what they should be doing, and posting information for others to read. Significant differences were found between the three campaigns for uses of these computer networks. The Clinton network was used more than the other two for posting information. The Perot network was used more than the others for asserting opinions. This study indicates that voters have specific functions for the use of computer networks as new channels of political communication. Future research should examine what groups of voters use these networks the most and how such use affects candidate image formation. Suggestions are offered for the study of campaign computer lists in the upcoming presidential election of 1996.  相似文献
