Inference Based on the Best-Fitting Model Can Contribute to the Replication Crisis: Assessing Model Selection Uncertainty Using a Bootstrap Approach     

Gitta H. Lubke  Ian Campbell 《Structural equation modeling》2016,23(4):479-490

Inferences and conclusions drawn from model fitting analyses are commonly based on a single “best fitting” model. If model selection and inference are carried out using the same data model selection, uncertainty is ignored. We illustrate the Type I error inflation that can result from using the same data for model selection and inference, and we then propose a simple bootstrap-based approach to quantify model selection uncertainty in terms of model selection rates. A selection rate can be interpreted as an estimate of the replication probability of a fitted model. The benefits of bootstrapping model selection uncertainty are demonstrated in growth mixture analyses of data from the National Longitudinal Study of Youth, and a 2-group measurement invariance analysis of the Holzinger–Swineford data.  相似文献   

Mnemonic artwork-learning strategies: Helping students remember more than “Who painted what?”     

Todd M. Franke  Joel R. Levin  Russell N. Carney 《Contemporary educational psychology》1991,16(4)

In two experiments, a recently devised mnemonic strategy was examined in the context of college students recalling the theme and contents of various paintings. With the painting-artist mnemonic strategy: (a) the artist's name is first recoded as a more concrete proxy; and (b) the recoded stimulus is then related to a prominent feature of the painting. Previous research has demonstrated that such a strategy enhances students' recall of artist names when cued with the associated paintings. The present study extends those findings by demonstrating that the strategy similarly facilitates students' recall of paintings and painting information when cued with the associated artist names. Of three different mnemonic variations included, one that incorporates a verbally described mnemonic interaction into the painting proved most effective. Suggestions for future research and educational implications are included in the discussion.  相似文献   

Sexual reconviction rates in the United Kingdom and actuarial risk estimates     

Craig LA  Browne KD  Stringer I  Hogue TE 《Child abuse & neglect》2008,32(1):121-138

OBJECTIVE: Assessing the risk of further offending behavior by adult sexual perpetrators of children is highly relevant and important to professionals involved in child protection. Recent progress in assessing risk in sexual offenders has established the validity of actuarial measures, although there continues to be some debate about the application of these instruments. This paper summarizes the debate between clinical and actuarial approaches and reviews the "base rate" for United Kingdom sexual offense reconviction. METHOD: A review of the literature revealed 16 UK sexual reconviction studies, 8 using incarcerated samples (N=5,915) and 8 using non-incarcerated samples (N=1,274). UK estimates of sexual reconviction rates are compared with European and North American studies. RESULTS: The mean sexual reconviction rates for the incarcerated sample at 2 years (6.0%), 4 years (7.8%) and 6 years or more (19.5%) were higher than that of the comparative non-incarcerated sample at 2 years (5.7%), up to 4 years (5.9%), and 6 years or more (15.5%). The overall sexual reconviction rate for both samples combined was 5.8% at 2 years, and 17.5% at 6 years or more. CONCLUSIONS: The sexual reconviction rate for incarcerated sexual offenders is higher than that of non-incarcerated sexual offenders. The UK sexual reconviction rates were comparable with European and North American studies.  相似文献   

The long-term preservation of identifiable personal data: a comparative archival perspective on privacy regulatory models in the European Union,Australia, Canada and the United States     

Livia Iacovino  Malcolm Todd 《Archival Science》2007,7(1):107-127

This article analyses the extent to which archival exemptions for historical, scientific and statistical research in privacy legislation support preservation in selected European Union countries, and comparable aspects of Australian, American and Canadian law within a legal, ethical and digital archival perspective. The authors recommend that the further processing of personal data under data protection law be given a wider scope of interpretation for archival preservation purposes in both the public and private sector, coupled with the use of researcher and archival codes in relation to access to personal data. They also recommend early appraisal and integration of privacy with freedom of information and archival regimes.

Examining features of how professional development and enactment of educative curricula influences elementary science teacher learning     

Ellen M. Granger  Todd H. Bevis  Sherry A. Southerland  Yavuz Saka  Fengfeng Ke 《科学教学研究杂志》2019,56(3):348-370

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in 4th—5th grades) that met the What Works Clearinghouse standards without reservations, teacher learning was conceptualized using four outcomes. Data were analyzed using standard single-level multiple regression models and possible mediation models for the teacher outcomes were considered using piecewise multiple regression and path analytic approaches. Treatment group teachers experienced greater increases in content knowledge, views of science inquiry, beliefs about reform-based teaching, and teaching self-efficacy than comparison group teachers. The findings indicate that what teachers learn from the combination of professional development and teaching with educative curriculum varies according to what their knowledge and beliefs are on entering the experience. Surprisingly, high entry-level self-efficacy was associated not only with lower learning gains for the teachers, but also for their students. Finally, teachers' space science learning and that of their students are implicated as mediators of the positive effect of the professional development and educative curriculum enactment on teacher beliefs about reform science teaching. This work refines and extends a theoretical framework of teachers' participatory relationship with curricula.  相似文献   

Attachment,Communication, and Relationship Functioning Among College Student Veterans and Nonveterans     

Shelley A. Riggs  Kellye S. Carver  Daniel Romero  Sandra B. Morissette  Jamie Wilson  Robyn Campbell  James McGuffin 《Journal of College Counseling》2019,22(2):110-124

This study examined attachment processes of college student veterans and nonveterans and further examined how veteran status and attachment style directly and indirectly predict relationship functioning. Results indicated that student veterans were more often dismissing in their attachment style but less often preoccupied than nonveteran students. Veteran status moderated the association between attachment style and dyadic consensus. The contributions of attachment and communication processes to overall relationship adjustment differed for student veterans and nonveterans.  相似文献

The promise of action research for critically reflective teacher education     

Todd Dinkelman 《The Teacher Educator》2013,48(4):250-274

Abstract

This paper is an analysis of the potential that action research theory and practice hold for educating preservice teachers to become more critically reflective. First, action research theory, especially as it informs current notions of educational research and practice, is reviewed. Then critically reflective teaching is described by grounding the term in critical social science views supportive of the social reconstructionist reform tradition in teacher education. Special attention is given in this review to the claims made by action research advocates regarding the power of action research to promote critically reflective teaching. Finally, to examine the empirical basis for these claims, a brief survey is made of several reports of the use of action research by teacher educators. The analysis reveals cautious optimism for the promise action research holds for critically reflective teacher education.  相似文献
