Average Effect Sizes in Developer-Commissioned and Independent Evaluations     

Rebecca Wolf  Jennifer Morrison  Amanda Inns  Robert Slavin  Kelsey Risman 《Journal of research on educational effectiveness》2020,13(2):428-447

Abstract

Rigorous evidence of program effectiveness has become increasingly important with the 2015 passage of the Every Student Succeeds Act (ESSA). One question that has not yet been fully explored is whether program evaluations carried out or commissioned by developers produce larger effect sizes than evaluations conducted by independent third parties. Using study data from the What Works Clearinghouse, we find evidence of a “developer effect,” where program evaluations carried out or commissioned by developers produced average effect sizes that were substantially larger than those identified in evaluations conducted by independent parties. We explore potential reasons for the existence of a “developer effect” and provide evidence that interventions evaluated by developers were not simply more effective than those evaluated by independent parties. We conclude by discussing plausible explanations for this phenomenon as well as providing suggestions for researchers to mitigate potential bias in evaluations moving forward.  相似文献   

Peer rejection and social information-processing factors in the development of aggressive behavior problems in children   总被引：21，自引：0，他引：21  

Dodge KA  Lansford JE  Burks VS  Bates JE  Pettit GS  Fontaine R  Price JM 《Child development》2003,74(2):374-393

The relation between social rejection and growth in antisocial behavior was investigated. In Study 1,259 boys and girls (34% African American) were followed from Grades 1 to 3 (ages 6-8 years) to Grades 5 to 7 (ages 10-12 years). Early peer rejection predicted growth in aggression. In Study 2,585 boys and girls (16% African American) were followed from kindergarten to Grade 3 (ages 5-8 years), and findings were replicated. Furthermore, early aggression moderated the effect of rejection, such that rejection exacerbated antisocial development only among children initially disposed toward aggression. In Study 3, social information-processing patterns measured in Study 1 were found to mediate partially the effect of early rejection on later aggression. In Study 4, processing patterns measured in Study 2 replicated the mediation effect. Findings are integrated into a recursive model of antisocial development.  相似文献   

The Promise of Restorative Practices to Transform Teacher-Student Relationships and Achieve Equity in School Discipline     

Anne Gregory  Kathleen Clawson  Alycia Davis  Jennifer Gerewitz 《Journal of educational and psychological consultation》2016,26(4):325-353

ABSTRACT

Restorative approaches to school discipline are increasingly being implemented throughout the United States in an attempt to reduce reliance on suspension and eradicate the racial discipline gap. Yet, little is known about the experience of students in classrooms utilizing restorative practices (RP). This study draws on student surveys (N = 412) in 29 high school classrooms. Hierarchical linear modeling and regression analyses show that high RP-implementing teachers had more positive relationships with their diverse students. Students perceived them as more respectful and they issued fewer exclusionary discipline referrals compared with low RP implementers. In addition, the findings demonstrate some initial promise of well-implemented RP for narrowing the racial discipline gap. The study found that higher RP implementers issued fewer discipline referrals to Latino and African American students compared with lower RP implementers. The study findings have implications for equity-focused consultation in schools that honor student experience of new programming.  相似文献   

Posthumanist ethical practice: agential cuts in the pedagogic assemblage     

Jennifer Charteris  Adele Nye  Marguerite Jones 《International journal of qualitative studies in education》2019,32(7):909-928

With researchers funnelled into lucrative research practices that value fast scholarship, we explore ethical practice as an ethico-onto-epistemological project. Through collective biography, diffractive choreography, and poetry, we map systems of entrapment that manifest power relations in the academy. We argue the posthumanist ethical practice is an intra-active project in higher education – involving rich material, social, political and intellectual entanglements. Posthumanist ethical practice rejects dualisms of body/mind, nature/culture and human/non-human. It evokes creativity to generate new vocabularies for challenging anthropocentric ‘exceptionalism’. Mapping relations in posthuman assemblages can involve agential cuts that evoke ethical practice as affective encounters. Agential cuts give permission for pedagogic storying where there is ontological connectedness. As academics, we are immersed in assemblages where posthumanist education research and practice is a rich, embodied, and connected process. Particular consideration is given in this article to affectivity and the value of pedagogic performance in education research.  相似文献   

Struggling with capital: a Bourdieusian analysis of educational strategies among internationally mobile middle class families in Sweden

ABSTRACT

Drawing on empirical data regarding educational strategies among internationally mobile families in the Stockholm-Uppsala region, this study questions the notion of a global middle class. First, a quantitative analysis shows that immigrating middle class professionals and their children are few, having marginal impact on the demand for international education. Furthermore, they far from constitute a homogeneous class, instead comprising of fractions opting for different types of schools. A second, qualitative study on capital conversion among mobile families illustrates that even well-educated international movers face serious challenges converting their existing knowledge, skills and contacts into well-informed social, professional and educational strategies in their new context. This suggests the limitations of concepts such as international capital. It is argued that the GMC concept overshadows the fact that social groups within the middle classes have varying degrees of international mobility that constitutes just one dimension of what separates them from each other.  相似文献   

Maternal Socialization of Children''s Eating Habits: Strategies Used by Obese Mexican-American Mothers   总被引：4，自引：0，他引：4  

Norman Olvera-Ezzell  Thomas G. Power  Jennifer H. Cousins 《Child development》1990,61(2):395-400

Mexican-Americans are more likely to be obese than the general population, yet little research has been conducted on the socialization of eating habits in Mexican-American children. 38 obese mothers enrolled in a weight-loss program and their 4-8-year-old children were observed during mealtime and the mothers interviewed about their socialization practices. Mothers relied primarily on nondirective verbal control strategies during the observation. Child compliance was more likely to follow a maternal serving or command than a nondirective behavior. Mothers encouraged sons to eat more than did mothers of girls. Child age was negatively correlated with mother's use of commands, reasoning, threats, and bribes, and positively correlated with maternal nondirectives, servings, and child compliance. Mothers with more years of formal education served healthier foods and were more likely to report using reasoning strategies, prohibiting consumption of unhealthy food, monitoring child food consumption away from home, and allowing child input into the eating situation than were less educated mothers.  相似文献

Middle school teachers’ differing perceptions and use of curriculum materials and the common core     

Amy Roth McDuffie  Jeffrey Choppin  Corey Drake  Jon D. Davis  Jennifer Brown 《Journal of Mathematics Teacher Education》2018,21(6):545-577

Eight middle school mathematics teachers’ perceptions and uses of curriculum materials and the Common Core State Standards for Mathematics (CCSSM) were investigated. Adapting a noticing framework and models of dialogic instruction and direct instruction, teachers’ noticing practices with curriculum materials and the CCSSM when planning, enacting, and reflecting on lessons were examined. Teachers who were committed to implementing the CCSSM and who were using one of two substantively different curriculum programs were purposefully selected. Data sources included multiple forms of interviews and classroom observations. The teaching evidenced three distinct noticing patterns. These patterns indicated that teachers’ curriculum materials were associated with how teachers perceived and enacted the CCSSM. Teaching with a curriculum program that was designed as a thinking device prioritized the Standards for Mathematical Practice of CCSSM evidenced noticing that was consistent with dialogic instruction. Teaching with a curriculum program that was designed as a delivery mechanism prioritized the Content Standards of CCSSM and evidenced noticing consistent with direct instruction. Findings indicated that the designated curriculum and contributed to differing interpretations of CCSSM and served as a lens for noticing. However, a dialogic curriculum program was not sufficient to support dialogic approaches in practice. One pattern showed teachers planning dialogic lessons, but the lesson enactments were not consistent with teachers’ plans, with evidence that the teachers were not aware that their practices differed from dialogic approaches. Implications for research and practice are discussed.  相似文献
