This study investigates relations between cognitive, interpersonal, and intrapersonal opportunities, noncognitive outcomes, and student achievement in 1,096 students from 20 high schools (10 Deeper Learning [DL] network, 10 control) who participated in the Study of DL (SDL). DL is an umbrella term used to encompass the cognitive, interpersonal, and intrapersonal skills and knowledge that students need to be successful in school and the workforce. Structural equation modeling (SEM) was used to test a theoretical model that hypothesizes plausible pathways between DL opportunities to interpersonal, intrapersonal, and cognitive outcomes. Further, a multigroup structural equation modeling examined differences in these relations between DL and matched nonnetwork schools. Cognitive and intrapersonal opportunities were related to both interpersonal and intrapersonal outcomes. Further, cognitive opportunities were indirectly related to student achievement through interpersonal outcomes. Similar patterns of relations were found in DL and control schools. This study helps to build a stronger understanding of how types of DL opportunities and strategies can best develop the complex skills that students need to be successful in school and can also be used to inform future intervention designs and research studies.  相似文献

This study examined the relative influence of three parenting behaviors (support, behavioral control, and psychological control) and deviant peers on trajectories of externalizing and internalizing problems in early adolescence. A white, working-to-middle-class sample of adolescents and their mothers and fathers in two-earner families participated in a 32-year longitudinal study (N = 109 families). The study began when the adolescents were in sixth grade (M age = 11.5 years). Analyses showed that parents' firm behavioral control seemed to halt the upward trajectory in externalizing problems among adolescents with deviant peers. Initial levels of internalizing problems were higher among adolescents with parents who reported lower levels of behavioral control and among adolescents with deviant peers. This study suggests that parenting exerts an important influence in adolescents' lives and may do so even in the face of potentially negative peer influence.  相似文献

ABSTRACT

This study examines whether professional journalists reason differently about moral problems when primed with their professional identity. This between-subjects experiment (N?=?171) used the Defining Issues Test, a much-used and validated instrument that measures moral reasoning. The results show identity priming does not affect how journalists apply ethics. The study also found that journalists score far lower in moral reasoning than they did 13 years ago. These results are interpreted through the lens of social identity theory.  相似文献

Weeding academic library collections is widely acknowledged as a necessary and beneficial, but difficult, task. Little research has been done on how librarians approach weeding for a particular academic subject area and how they apply general weeding plans and criteria to a specific subject. This project examines the weeding practices of librarians with responsibility for managing book collections in political science and related disciplines through the use of a survey about their weeding experiences and perspectives. While survey respondents expressed similar motivations for weeding, the obstacles they encounter, and their approaches to developing weeding projects to those outlined in the literature, respondents were more confident about weeding and do it more frequently than one would expect from prior scholarship. Open text responses gave insight into how librarians apply broad and subjective weeding criteria, such as currency and relevance, to their politics-related collections.  相似文献

Individuals frequently engage in self-presentation via social media and can subsequently receive various simple communicative cues (paralinguistic digital affordances; PDAs) from which they may determine the success of their self-presentation, including Likes and Upvotes. Previous research has found these communicatively abstract one-click cues are interpreted idiosyncratically when received, but the quantity received matters to users in determining whether a post is “successful.” The present work probes explanatory mechanisms behind the use of PDA responses as a metric of self-presentational success, deriving hypotheses from social comparison theory, social penetration theory, and expectancy violations theory. Results from a survey (N = 255) reveal that social comparison and communicative reciprocity provide explanatory power regarding the threshold of Likes and Reactions to a Facebook post needed to consider a post successful.  相似文献

Research examining family influences on student motivation and achievement in school has generally focused on parental influences and has often been limited to one or two variables (e.g., parental expectations or aspirations, parental involvement in schoolwork). In the present study we interviewed high school seniors to examine whether and how family members affected their academic motivation and achievement. Interviews were coded holistically for the strength, affective tone, source, and types of familial influence. Emergent themes from the interview analyses revealed that students perceived a broad range of types and sources of familial influence on motivation. Interviews were divided into five prototypical patterns: Family Obligation, Family Pleasing, Family Support, Aversive Influence, and No Influence. The types of familial influence differed by cultural characteristics (generational status, native country) and by achievement level. Associations between the five patterns of family influence and existing theories of family influence are discussed.  相似文献

Purpose:This systematic review and meta-analysis aimed to evaluate the effect of wearable devices for improving physical activity and healthrelated outcomes in cancer survivors.Methods:CINAHL,Cochrane,Ebscohost,MEDLINE,Pubmed,ProQuest Health and Medical Complete,ProQuest Nursing and Allied Health Source,ScienceDirect,and SPORTDiscus databases were searched for randomized controlled trials published before September 1,2020,that evaluated interventions involving wearable devices in cancer survivors.Standardized mean differences(SMDs)were calculated to assess effects on physical activity and health-related outcomes.Subgroup analyses were conducted to assess whether the effects differed by interventions and cancer characteristics.Risk of bias was assessed using the Cochrane risk of bias tool.Results:Thirty-five trials were included(breast cancer,n=15,43%).Intervention durations ranged between 4 weeks and 1 year.Most trials(n=25,71%)involved pedometer-based physical activity interventions.Seven(20%)involved Fitbit-based interventions,and 3(9%)involved other wearable physical activity trackers(e.g.,Polar,Garmin).Compared to usual care,wearable devices had moderate-to-large effects(SMD range 0.54-0.87,p<0.001)on moderate-intensity physical activity,moderate-to-vigorous-intensity physical activity,total physical activity,and daily steps.Compared to usual care,those in the intervention had higher quality of life,aerobic fitness,physical function,and reduced fatigue(SMD range=0.18-0.66,all p<0.05).Conclusion:Wearable physical activity trackers and pedometers are effective tools that increase physical activity and improve health-related outcomes in individuals with cancer.Identifying how these devices can be implemented for longer-term use with other intervention components remains an area for future research.  相似文献

Through five waves of data collection, this longitudinal study investigated the development of spatial skills in 304 elementary school children (Mage = 7.64 years) as they progressed from the second to fourth grade. The study focused on whether multiple latent classes with different developmental profiles best explain development. Spatial skills were measured by tests featuring two‐dimensional figures. Mathematics achievement was measured by the statewide end‐of‐year test and was included as a distal outcome variable. The role of covariates, including socioeconomic status, verbal working memory, and gender, was also explored. The results indicate a need to view two‐dimensional spatial skills development as multidimensional with two developmental profiles predicted by socioeconomic status, verbal working memory, and gender. The developmental profiles predicted differences in mathematics achievement.  相似文献
