This study seeks to understand the emotional connection of teachers' academically productive talk (APT) with student learning from the students' perspective. Using a sample of 2,225 students (N7th grade = 1,146 and N8th grade = 1,079) from 16 middle schools in a city of China, we investigate the relationship between students' perceptions of their teachers’ APT, student emotions (enjoyment and anxiety) and their discursive engagement with others in the mathematics classroom. Results from structural equation modelling and mediation analysis show that after controlling for gender, family resources and mathematics achievement, student-perceived teacher APT was positively associated with their discursive engagement with classmates. Furthermore, student enjoyment and anxiety in class mediated the relationship between student-perceived teacher APT and student discursive engagement with classmates. Multi-group analysis revealed that the model was invariant across genders and grades, indicating that the associations were applicable to male and female students as well as to seventh and eighth graders. These findings shed light on the emotional relationship of teacher APT with the discursive engagement of their students. Although prior research observes a positive relationship between teacher productive classroom talk and student discursive engagement primarily through classroom observations and teacher reflections, this study provides evidence from the students’ perspective and highlights the mediating role of student emotions in the relationship. 相似文献

BackgroundMethodological issues have been identified when quantifying exposure to adversity and abuse. To address a single type may obscure covarying effects. To sum multiple exposures gives equal weight to each. Latent class analysis (LCA) addresses this by identifying homogenous subpopulations. Most studies using LCA have pooled gender data in spite of evidence that the nature and frequency of exposure differs by gender. Males report more interpersonal abuse, females report more of other exposures, particularly sexual.ObjectiveThis study aimed to identify if stratifying data by gender resulted in different profiles of adversity/abuseParticipants and setting: The National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) wave II, a large community-based survey, nationally representative of the US population.MethodThis study used 14 indicators of childhood adversity as the basis for LCA.ResultsThe number and nature of classes differed by gender. The best solution for females was 4-class: a low risk class; a class at higher risk of sexual abuse; a class at higher risk of physical abuse; a class at higher risk of combined physical and sexual abuse. The best solution for males had only 3-classes; a low risk class, a class at higher risk of sexual abuse; a class at higher risk of physical abuse. The combined dataset resulted in a solution similar to the female solution.ConclusionThe importance of developing models for males and females separately was evidenced by the male and female classes being differentially associated with mental health variables. 相似文献

BackgroundAlthough adverse childhood experiences (ACEs) are relatively common among children, there is limited knowledge on the co-occurrence of such experiences.ObjectiveThe current study therefore investigates co-occurrence of childhood adversity in the Netherlands and whether specific clusters are more common among certain types of families.Participants and SettingRepresentative data from the Family Survey Dutch population 2018 (N = 3,128) are employed.MethodWe estimate Latent Class Analysis (LCA) models to investigate co-occurrence of ACEs. As ACEs we examine maltreatment, household dysfunction, demographic family events, as well as financial and chronic health problems. Gradual measures for maltreatment and financial problems are studied to make it possible to differentiate with regard to the severity of experiences.ResultsOur results show that four ACE clusters may be identified: ‘Low ACE’, ‘Moderate ACE: Household dysfunction’, ‘Moderate ACE: Maltreatment’ and ‘High ACE’. Regression analyses indicated that mother’s age at first childbirth and the number of siblings were related to experiencing childhood adversity. We found limited evidence for ACEs to be related to a family’s socioeconomic position.ConclusionThe found clusters of ACEs reflect severity of childhood adversity, but also the types of adversity a child experienced. For screening and prevention of childhood adversity as well as research on its consequences, it is relevant to acknowledge this co-occurrence of types and severity of adversity. 相似文献

全球儿童青少年的肥胖发病率逐年增高,身体活动不足,每天参加足够量的身体活动是促进其身心健康发展的基本保障。我国儿童青少年面对繁重的学业和大量的家庭作业,课外体育活动参与的时间大大减少,体育课成为了唯一能促使学生参与中等到大强度身体活动的场所。通过SOFIT工具对上海市黄浦区5所小学的217节体育课的学生身体活动水平和教师教学行为进行了观测,分析发现:上海市小学生体育课中的身体活动水平偏低,能够达到50%以上时间进行中等到大强度身体活动(MVPA)的课时比率非常少。教师用于课堂管理和知识讲解的时间过多,且对促进学生进行MVPA的语言干预不够,这些均影响了学生的课内身体活动水平。建议除对学生的活动时间高度重视外,还应该重视学生课内身体活动强度;体育教师应做到“精讲多练”,推动学生积极的参与体育活动;注重开发优质的体育课程。 相似文献

This article explores how parents choose childcare settings for their pre-school children within a context of complex policy on eligibility for free provision and a developing market. Using data from interviews with 17 mainly middle-class parents in England, we explore in detail how parents go about choosing a childcare setting and the different phases of this process. This adds further nuance to the existing literature on choosing practices and the dysfunction and inequalities of a neoliberal childcare market, and also updates the discussion to include recent policy developments such as the provision of ‘30 hours free childcare’ for 3 and 4-year-olds. We conclude that parental choosing involves a series of decisions in two or three phases, which start from practical considerations, followed by quality comparison and then back to practical constraints if a decision has not been made. The options open to parents are split between not only those able to accommodate shorter ‘free’ provision and those that require longer periods of childcare to work, but also between those with children under three and above. Contrary to previous findings in this area, this split may work to the disadvantage of some middle-class families, whose children attend lower-quality settings as a result. 相似文献
