Models and Strategies for Factor Mixture Analysis: An Example Concerning the Structure Underlying Psychological Disorders

The factor mixture model (FMM) uses a hybrid of both categorical and continuous latent variables. The FMM is a good model for the underlying structure of psychopathology because the use of both categorical and continuous latent variables allows the structure to be simultaneously categorical and dimensional. This is useful because both diagnostic class membership and the range of severity within and across diagnostic classes can be modeled concurrently. Although the conceptualization of the FMM has been explained in the literature, the use of the FMM is still not prevalent. One reason is that there is little research about how such models should be applied in practice and, once a well-fitting model is obtained, how it should be interpreted. In this article, the FMM is explored by studying a real data example on conduct disorder. By exploring this example, this article aims to explain the different formulations of the FMM, the various steps in building a FMM, and how to decide between an FMM and alternative models.  相似文献

OBSTACLES AND OPPORTUNITIES: CREATING EARLY CHILDHOOD PROFESSIONAL DEVELOPMENT SCHOOLS     

James C. Stroud  Patricia Clark 《Journal of Early Childhood Teacher Education》2013,34(1):39-46

Abstract

The purpose of this article is to highlight key findings from a study of 24 early childhood preservice teachers as they moved away from a reliance on traditional interpretations of child‐centered curricula toward one of collaborative inquiry. Participants enrolled in a 15 week undergraduate teaching methods course were assigned to teaching teams to implement collaborative projects with the same group of 3–5‐year‐old children. The study utilized both quantitative and qualitative measures to assess conceptual level, changes in reflectivity, and inquiry‐oriented teaching. Results suggest that the emergence of collaborative inquiry among preservice teachers is a dynamic and diverse process not readily assessed by static measures or discreet skills. Collaborative projects did provide a context for creating communities of learners within which time, space and opportunity to practice, reflect and use language and other tools contributed to young teachers’ development of inquiry.  相似文献

Committed to improving how their various programs serve student learning, Taran Cardone, Elizabeth Stoll Turton, Gerald Olson, and Marcia Baxter Magolda describe how their participation in Miami University's Community of Practice on Engaged Learning (COPEL) helped them create developmentally appropriate, learning‐centered approaches that support the complex task of student self‐authorship.  相似文献   

The Choice of Response Probability in Bookmark Standard Setting: An Experimental Study     

Peter Baldwin  Melissa J. Margolis  Brian E. Clauser  Janet Mee  Marcia Winward 《Educational Measurement》2020,39(1):37-44

Evidence of the internal consistency of standard-setting judgments is a critical part of the validity argument for tests used to make classification decisions. The bookmark standard-setting procedure is a popular approach to establishing performance standards, but there is relatively little research that reflects on the internal consistency of the resulting judgments. This article presents the results of an experiment in which content experts were randomly assigned to one of two response probability conditions: .67 and .80. If the standard-setting judgments collected with the bookmark procedure are internally consistent, both conditions should produce highly similar cut scores. The results showed substantially different cut scores for the two conditions; this calls into question whether content experts can produce the type of internally consistent judgments that are required using the bookmark procedure.  相似文献   

Automated Scoring of Constructed‐Response Science Items: Prospects and Obstacles     

Ou Lydia Liu  Chris Brew  John Blackmore  Libby Gerard  Jacquie Madhok  Marcia C. Linn 《Educational Measurement》2014,33(2):19-28

Content‐based automated scoring has been applied in a variety of science domains. However, many prior applications involved simplified scoring rubrics without considering rubrics representing multiple levels of understanding. This study tested a concept‐based scoring tool for content‐based scoring, c‐rater?, for four science items with rubrics aiming to differentiate among multiple levels of understanding. The items showed moderate to good agreement with human scores. The findings suggest that automated scoring has the potential to score constructed‐response items with complex scoring rubrics, but in its current design cannot replace human raters. This article discusses sources of disagreement and factors that could potentially improve the accuracy of concept‐based automated scoring.  相似文献   

Twenty-four-hour movement behaviours and fundamental movement skills in preschool children: A compositional and isotemporal substitution analysis     

Jéssica Gomes Mota  Cain Craig Truman Clark  Luís Lemos  Cézane Priscilla Reuter  Jorge Augusto Pinto Silva Mota 《Journal of sports sciences》2020,38(18):2071-2079

ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r² = 0.31), object control (r² = 0.19), and total motor score (r² = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.  相似文献

Caregivers' perceptions of emergent literacy programming in public libraries in relation to the National Research Councils' guidelines on quality environments for children     

Laura K. Clark 《Library & information science research》2017,39(2):107-115

A survey conducted at three Florida library systems examines caregivers' perceptions of emergent literacy programming and how these perceptions compare with the National Research Council's features for quality programs for children. The survey results reveal that caregivers' perceptions of emergent literacy programming align with the National Research Council's features. The data demonstrates that caregivers' perceptions are very positive toward emergent literacy programming in terms of learning and the environment. Caregivers' perceptions of the environment answers were mostly strongly agree. These results were more positive than their perceptions of learning, although they strongly agree that these programs prepare children for school, reading, and social interaction. The survey results will inform public libraries as to how to design, market, and deliver emergent literacy programming to caregivers with very young children.  相似文献
