Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed.  相似文献

Do sports help students stay away from misbehavior,suspension, or dropout?     

《Studies in Educational Evaluation》2021

This paper explores whether high-school sports are functional and accessible activities to keep students from school disciplinary behaviors. For this purpose, we included students racial and linguistic status, socioeconomic status, sex, and prior academic performance with the school’s proportion of free-lunch recipients and minorities, to understand how sport participation affects students of diverse groups. Additionally, the study implemented a multilevel mediation modeling to the Education Longitudinal Study (ELS) data and assessed student dropouts with sequential mediators of sport participation, school misbehavior, and suspension. The findings of the study largely revealed that White students participated in sports more than Black, Hispanic, and Asian. Likewise, students who speak English as the primary language and male students participated in sports more than their counterparts. White sport participants displayed fewer incidents of suspension than White non-sport participants. Black, Hispanic, and White sport participants had lower dropout incidents than their non-sport-participating counterparts.  相似文献   

Teacher judgments at zero-acquaintance: A social accuracy analysis     

《Contemporary educational psychology》2021

How accurate are teachers’ first impressions and what moderates the degree of first impression accuracy? In previous teacher judgment accuracy research, teachers judged students who were well-acquainted to them, focusing on single traits. Here, we follow the zero-acquaintance paradigm and apply the Social Accuracy Model (SAM; Biesanz, 2010) to examine teachers’ first impressions regarding students’ personality profiles. Three groups of perceivers (student teachers, experienced teachers and psychology students; N = 285) rated students’ (N = 10) academic self-concept, intrinsic motivation and intelligence based on brief videos. SAM analyses revealed that teachers were accurate regarding the average students’ profile of characteristics (normative accuracy), but were not successful at detecting students' unique personality profiles (distinctive accuracy). Moreover, likeable students and those evaluated as more physically attractive were perceived with higher normative accuracy. Personality similarity and teaching experience were unrelated to accuracy. Implications for teacher judgment accuracy research and educational practice are discussed.  相似文献

中小学教师专业核心素养模型构建研究     

何齐宗  刘流 《课程.教材.教法》2021,41(4):131-137

中小学教师专业核心素养是中小学教师从事教育教学活动所必备的基本素质。近年来我国有学者开始关注中小学教师的核心素养问题,但采用规范的方法研究中小学教师专业核心素养的成果还较少见到。本研究运用文献法、德尔菲法和统计法研讨了中小学教师专业核心素养的因素,在此基础上构建并分析了品德修为、知识涵养和教学能力三维度的中小学教师专业核心素养模型。该模型可以为中小学选聘教师、开展教师培训、评估教师绩效及中小学教师的自我发展提供有益的参考和启示。  相似文献   

基础教育质量的内涵与监测评价理论模型     

李刚  辛涛 《华东师范大学学报(教育科学版)》2021,(4):15-29

对基础教育质量内涵的理解需从形成规定性定义或纲领性定义转向给出描述性定义,包括:(1)教育质量的内涵是多要素、多层面的,需要建立起系统的教育质量观;(2)教育质量的核心是学生的发展;(3)学生的发展应当是全面的;(4)学生的发展是多因素作用的结果。基础教育质量监测评价的理论模型是对质量内涵的结构化呈现,其以CIPO(背景-输入-过程-产出)为框架,从学生发展角度对教育产出进行定义,并遴选关键影响因素,对教育质量的各层面各因素及其相互关系进行考察,最后从教育因素的作用这一视角表征教育质量。我国监测评价工作还需利用教育质量标准对基础教育质量进行明确定义,完善关键影响因素监测,加强对教育质量的追踪调查和实验研究,建构教育质量指数。  相似文献   

计及两阶段需求侧响应荷源协调消纳弃风调度模型     

杨晓辉  芮松宏  陈再星  徐青山  黄鑫 《实验室研究与探索》2021,(2):1-7

提出一种针对弃风消纳的日前日内两阶段调度模型。与传统的热电联合模型相比,引入了基于消费者心理学模型的价格需求响应,其通过极具代表性的历史数据拟合得来且充分考虑用户对电价的响应规律,更符合实际用户情况,最大程度对负荷进行削峰填谷以应对风电的反调峰特性,为风电上网提供空间。日内引入激励性需求响应协调调度,调度模型是以系统总经济成本最小为目标函数的混合整数规划问题。以某地电网为算例表明:所提模型有效,系统总运行经济成本明显减少,弃风状况得到改善。  相似文献   

基于馆校合作的美国教师教育课程探索及挑战     

付积  王牧华 《外国教育研究》2021,(2)

美国馆校合作教师教育课程是回应美国教育改革要求、变革传统教师教育模式以及深化馆校合作关系等各种因素综合作用的结果。美国大学和场馆在合作中探索和开发了具有不同特色的课程模式,研究将其分为场馆在线课程模式、场馆现场课程模式以及混合课程模式三种类型,并从课程规划与设计、课程内容、授课模式、课程管理、课程评估以及课程文化等不同维度,对不同课程模式的创新进行了研究和分析。但是,馆校合作教师教育课程在可持续发展方面仍然面临许多问题和挑战:如场馆经验的制度化、稳定的资金投入以及有效的课程管理。  相似文献
