Required Collaborative Work in Online Courses: A Predictive Modeling Approach          下载免费PDF全文

Marlene A. Smith  Deborah L. Kellogg 《Decision Sciences Journal of Innovative Education》2015,13(4):563-581

This article describes a predictive model that assesses whether a student will have greater perceived learning in group assignments or in individual work. The model produces correct classifications 87.5% of the time. The research is notable in that it is the first in the education literature to adopt a predictive modeling methodology using data collected via a designed experiment. All subjects experienced both a collaborative and an individual assignment, thus mitigating uncontrolled external factors in the measurement of differences in perceived learning. The exploratory nature of the work prompted the use of Partial Least Squares Regression for estimation. The work serves as an illustration of how predictive modeling might enlighten those in educational and academic settings.  相似文献   

A defensive mindset: A pattern of social information processing that develops early and predicts life course outcomes     

Kenneth A. Dodge  Yu Bai  Jennifer Godwin  Jennifer E. Lansford  John E. Bates  Gregory S. Pettit  Damon Jones 《Child development》2022,93(4):e357-e378

The hypothesis was tested that some children develop a defensive mindset that subsumes individual social information processing (SIP) steps, grows from early experiences, and guides long-term outcomes. In Study 1 (Fast Track [FT]), 463 age-5 children (45% girls; 43% Black) were first assessed in 1991 and followed through age 32 (83% retention). In Study 2 (Child Development Project [CDP]), 585 age-5 children (48% girls, 17% Black) were first assessed in 1987 and followed through age 34 (78% retention). In both studies, measures were collected of early adverse experiences, defensive mindset and SIP, and adult outcomes. Across both studies, a robust latent construct of school-age defensive mindset was validated empirically (comparative fit index = .99 in each study) and found to mediate the impact of early child abuse (38% in FT and 29% in CDP of total effect) and peer social rejection (14% in FT and 7% in CDP of total effect) on adult incarceration.  相似文献   

Parent–adolescent interaction quality and adolescent affect—An experience sampling study on effect heterogeneity

Person–environment interactions might ultimately drive longer term development. This experience sampling study (Data collection: 2019/20 the Netherlands) assessed short-term linkages between parent–adolescent interaction quality and affect during 2281 interactions of 124 adolescents (M_age = 15.80, SD_age = 1.69, 59% girls, 92% Dutch, Education: 25% low, 31% middle, 35% high, 9% other). Adolescents reported on parent–adolescent interaction quality (i.e., warmth and conflict) and momentary positive and negative affect five to six times a day, for 14 days. Preregistered dynamic structural equation models (DSEM) revealed within-family associations between parent–adolescent interaction quality and adolescent affect (concurrently: r = −.22 to .39; lagged effects: ß = −.17 to .15). These effects varied significantly between families. These findings stress the need for more person-specific research on parenting processes.  相似文献   

Maternal color-consciousness is related to more positive and less negative attitudes toward ethnic-racial outgroups in children in White Dutch families     

Judi Mesman  Ymke de Bruijn  Daudi van Veen  Fadime Pektas  Rosanneke A. G. Emmen 《Child development》2022,93(3):668-680

A prerequisite to anti-racist socialization in families is acknowledging ethnic-racial (power) differences, also known as color-consciousness. In a sample of 138 White Dutch families from the urban Western region of the Netherlands with children aged 6–10 years (53% girls), observations and questionnaires on maternal color-consciousness and measures of children's attitudes toward Black and Middle-Eastern ethnic-racial outgroups were collected in 2018–2019. Variable-centered analyses showed that maternal color-conscious socialization practices were related to less negative child outgroup attitudes only. Person-centered analysis revealed a cluster of families with higher maternal color-consciousness and less prejudiced child attitudes, and a cluster with the opposite pattern. The mixed results emphasize the importance of multiple methods and approaches in advancing scholarship on anti-racism in the family context.  相似文献

Organisational forms of science communication: the UK and Spanish European higher education systems as paradigms     

Ojeda-Romano  Gabriela  Fernández-Marcial  Viviana  Wilkinson  Clare  Stengler  A. Erik 《Higher Education》2022,84(4):801-825

As key elements in research and development systems, higher education institutions have been taking a leading role when it comes to communicating science and technology, but their performance has been inconsistent so far. In this critical and comparative study of the UK public engagement model and the Spanish scientific culture model, eighteen practitioners from higher education institutions across both regions were interviewed. A mixed qualitative data analysis has been performed identifying similarities and differences that unravelled the science communication management model in the two different higher education systems. This article provides evidence on how the institutionalisation of science communication is strongly influenced by key driving forces in the higher education context as well as the policies of administrations and other agents.

Exploring the experiences and responses of LGBTQ+ adolescents to school-based sexuality education     

Shereen C. Naser  Katherine Clonan-Roy  Kimberly A. Fuller  Elizabeth A. Goncy  Nicole Wolf 《Psychology in the schools》2022,59(1):34-50

The purpose of this study is to describe the experiences of lesbian, gay, bisexual, transgender, questioning, intersex, two spirit, and queer (LGBTQ+) youth with school-based sexuality education (SBSE), as well as to document strategies LGBTQ+ youth are using to address their evolving and specific sexual health needs outside of SBSE. Researchers conducted focus groups with 17 adolescents (ages 14–18) from urban and suburban Midwestern cities. Results of this study indicate LGBTQ+ youth find SBSE to be heteronormative, cisgender focused, and primarily focused on pregnancy and disease prevention, which contributes to LGBTQ+ youth experiences of exclusion. In response to SBSE that did not meet student needs, participants reported seeking sexual health information outside of SBSE. Other sources included family and other trusted adults, the Internet, and community resource centers. Students reported variable rates of use and trustworthiness across these resources. Results of this study suggest that school personnel should consider alternatives to traditional SBSE models to meet the needs of LGBTQ+ youth, and that an important part of SBSE should include guidelines for Internet safety.  相似文献
