Situational Indexes of Achievement Motivation,Help-Seeking,and Performance: Influences of the Learning Context and Gender Differences     

Christophe Gernigon  Fabienne D'arripe-Longueville  Véronique Debove  Aude Puvis 《Research quarterly for exercise and sport》2013,84(4):473-479

Abstract

Sixteen college athletes and non-athletes were given 10 30-sec. practice trials to learn how to balance on a stabilometer. The next day they were allowed three more trials alone and three trials before a group of spectators. The non-athletes were significantly better on two of the three trials performed in front of the spectators. They also performed better than the athletes throughout the ten practice trials, although the tenth and last trial approached but did not yield a significant difference at the .05 level.  相似文献

Emotion regulation and academic perceptions in adolescence     

Rylee Oram  Julia Ryan  Maria Rogers  Nancy Heath 《Emotional and Behavioural Difficulties》2017,22(2):162-173

Although studied extensively in the field of adolescent mental health, the role of emotion regulation (ER) in the academic functioning of adolescents is not well understood. This study examined the role of ER in adolescents’ perceptions of themselves and their learning environments. We compared adolescents with high and low levels of ER on perceptions of school achievement and attitudes towards school and their perception of their parents’ academic involvement. Students completed surveys about perceptions of their learning and parental involvement, as well as their ER abilities. Results indicated that students with higher emotion dysregulation endorsed more negative self-perceptions of their own academic abilities, had more negative attitudes towards school, and rated their mothers and fathers as more controlling in relation to their learning. These results demonstrate the importance of ER in the academic context, particularly in the home learning environment.  相似文献   

Has family involvement migrated into higher education? An investigation of how administrative staff document the phenomenon in students’ university experiences in Cyprus     

Loizos Symeou  Eleni Theodorou  Iasonas Lamprianou  Konstantina Rentzou  Panayiota Andreou 《International Studies in Sociology of Education》2018,27(1):78-99

Families have been getting more and more involved in their children’s education. This paper presents findings of a study investigating family involvement in their members’ undergraduate studies attending a state (non-fee-paying) and a private (fee-paying) university in Cyprus. The data presented in the paper were collected via online logs completed by administrative personnel in the two universities documenting incidents of family involvement. The data analysis demonstrates how similarly the phenomenon manifests in both universities and suggests that where the two universities differ is more in the intensity of the various modes of family involvement. It also projects students’ desires and encouragement of their family’s involvement and their families’ intervention to protect or guide them. The findings of the study are discussed in view of cultural and societal norms and changes about parenthood and the relationship between families and their university age members in a marketized higher education context.  相似文献

The role of invitations to parents in the completion of a child’s home reading challenge     

Orla Colgate  Paul Ginns  Nigel Bagnall 《教育心理学》2017,37(3):298-311

The role parents can play in supporting early reading attainment is well documented. There is still, however, a need to understand what motivates parents to become involved in reading at home with their child. Past research, based upon correlational studies, has mixed findings regarding the influence of the teacher and the child on parents’ motivation at home. Through two quasi-experiments, the present study explored the influence of teacher invitations in Kindergarten classes, and child invitations in Grade 2 classes on completion rates of a home reading challenge. The completion of the home reading among families was investigated across two metropolitan schools in Sydney, Australia. Both of the interventions resulted in significantly higher completion rates compared to control groups (teacher invitations: d = .68; child invitations: d = .73). This paper adds to existing research by providing a clearer picture of the cause-and-effect relationship between schools’ use of invitations to facilitate children’s home reading.  相似文献   

‘Start treating me like a Dad!’ The impact of parental involvement in education on the paternal identity of fathers in the English prison system     

Helen O’Keeffe 《Cambridge Journal of Education》2019,49(2):197-213

Notwithstanding the increasing number of UK and international studies focused on parental involvement in education and parental imprisonment there remains little focus upon the involvement of imprisoned fathers in children’s education and the impact of this upon paternal identity. Despite the now accepted perspective that parental imprisonment often impacts negatively on family functioning, child outcomes and parental identity, this qualitative study is distinctive in drawing on the discourse of parental involvement in education, using the lens of identity theory to examine the experiences of 15 imprisoned fathers regarding their involvement in their children’s education and their parenting possible selves as educators. Participants demonstrated limited identity standards in relation to education and sometimes a reduced commitment as a result of this. All offered a vision of their possible selves as educators if contextual barriers were addressed. Possible implications are suggested.  相似文献   

美国家长参与学校教育管理角色的嬗变     

《教育研究》2007,(6)

美国家长对学校教育管理的参与经历了从参与学校教育到参与学校管理、从消极被动参与到积极主动参与、从一元管理主体到多元管理主体、由封闭走向开放、由"局外人"向"局内人"角色演变的过程。20世纪80年代以前,家长参与侧重于学校的教学业务性活动,80年代以后,随着美国基础教育的深刻变革,家长参与逐步深入到学校的决策层面,其角色由"局外人"转为"局内人"。作为集决策者、合作者和公共教育购买者于一身的家长,他们以主人翁的身份参与学校决策,积极承担管理责任、履行服务义务,从而形成了富有美国特色的民主开放型的家校合作的教育管理文化。  相似文献
