Student engagement is an important contributor to school success, yet high school students routinely describe themselves as
disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement.
This study investigated students’ perceptions of autonomy, teacher connection, and academic competence as predictors of changes
in student engagement within the classroom from the start to the end of a course. Participants were 578 (58% female) diverse
(67.8% White, 25.2% African American, 5.1% Hispanic, 1.2% Asian American) high school students from 34 classrooms who provided
questionnaire data both at the start and the end of a single course. Novel results from a cross-lagged model demonstrated
that students who perceived their classrooms as allowing and encouraging their own autonomy in the first few weeks increased
their engagement throughout the course, rather than the typical decline in engagement that was demonstrated by students in
other classrooms. This finding is unique in that it extended to both students’ perceptions of engagement and observations
of student engagement, suggesting a fairly robust pattern. The pertinence of this finding to adolescent developmental needs
and its relationship to educational practice is discussed. 相似文献

An accruing body of evidence supports associations between self-perceived gender typicality and peer relationship difficulties; however, researchers have yet to evaluate peers' perceptions of problem behaviors to gain insight into the social correlates of gender typicality. A short-term longitudinal study was conducted to evaluate associations between gender atypical problem behavior and subsequent peer relational difficulties for 2,076 fifth graders (M age= 10.27; 53% female). Peer nomination methodology was used to assess participants' classroom peer relationships, problem behaviors, and social-emotional characteristics. Findings showed that youth characterized by gender atypical, compared to gender typical, problem behavior (withdrawn boys/aggressive girls vs. withdrawn girls/aggressive boys, respectively) evidenced higher levels of subsequent peer difficulties; moreover, participation in a mutual friendship was associated with decreased risk for peer relationship maladjustment, particularly among youth characterized by gender atypical problem behavior. Results further revealed that, compared to friendless youth, friended youth earned higher prosocial and peer liking scores and, for withdrawn youth, lower emotional sensitivity scores. The present research contributes to our understanding of the potential short-term consequences of youth's gender atypical problem behavior. Findings underscore the need for supplemental conceptualizations of gender typicality as well as multifaceted interventions designed to promote the acceptance of gender nonnormativity, support the development of adaptive peer relationships, and reduce the occurrence of problem behaviors. 相似文献

在所有养骆驼的国家,锥虫感染都引起严重的发病率(达30%)和死亡率(约3%),其中最重要的是苏拉病,即伊氏锥虫(Trypanosoma evansi)感染。这是Evans氏于1880年在印度首先发现和研究的。在非洲,Cazalbou氏早在1896年也曾在马里的Timbuktu地方研究过此病。在苏联,由柯雅二氏锥虫T.ninae kohl—yakimov)在双峰驼所致的锥虫病称作“Su—auru”,这是一个哈萨克名称,意思是“来源于水的疾病”。锥虫病是乍得的骆驼 相似文献

General practitioners (GPs) are assumed to occupy an important position in the prevention of suicide through the introduction of risk assessment techniques commonly used in psychiatric practice. Despite this theoretical role for primary care services, it remains unclear how frequently GPs implement risk assessment in patients who may be vulnerable to suicide. To address this, a retrospective survey of probable suicides was conducted within a primary care setting utilizing a questionnaire of GPs who had experienced a patient suicide and was augmented by hospital and coroners' records. 85% of questionnaires were returned and 61 deaths were adjudged as suicides during the year long census period. 75% of suicides were male and 54% were aged under 35.28% were in contact with psychiatric services prior to death, although 60% had some diagnosis of mental disorder. GPs had little knowledge of a patient's life circumstances in up to half of cases. Recording of risk assessment occurred in 38% of subjects, was positively associated with prior psychiatric contact (p = 0.001) but negatively associated with presence of physical illness (p = 0.004), older patient age (p = 0.04), and GPs length in practice (p = 0.05). One GP felt their suicide case was preventable. The low rate of risk assessment and limited knowledge of patient lifestyle point to the need for active engagement of GPs in future suicide prevention strategies and should influence the content of training programs in primary care. 相似文献
