本研究意在考查动态测验对数学学习困难儿童作进一步程度区分的有效性。以传统且常用的数学学习困难鉴别方式和标准选取30名四年级数学学习困难儿童为实验组,30名同年级智力匹配儿童为对照组,以Swanson认知加工测验(S-CPT)的4个子测验为测量工具对被试进行动态测验。结果发现:(1)在传统数学学习困难鉴别方式的基础上,动态测验的“潜在认知能力”指标可以对儿童数学成绩增加19%的预测力;(2)以“潜在认知能力”指标为依据能够将数学学习困难儿童进一步区分为“发展落后”和“发展缺陷”两个水平;(3)“发展落后”儿童一年内数学成绩发生了增长性变化,与正常儿童水平相当,而“发展缺陷”儿童的数学成绩没有变化。研究证实关注潜能指标的动态测验范式在快速、准确甄别数学学习困难儿童上具有独特效用。 相似文献

Smartphones have become a prevalent technology as they provide employees with instant access to work-related information and communications outside of the office. Despite these advantages, there may be some costs of smartphone use for work at night. Drawing from ego depletion theory, we examined whether smartphone use depletes employees’ regulatory resources and impairs their engagement at work the following day. Across two studies using experience sampling methodology, we found that smartphone use for work at night increased depletion the next morning via its effects on sleep. Morning depletion in turn diminished daily work engagement. The indirect effects of smartphone use on depletion and engagement the next day were incremental to the effects of other electronic devices (e.g., computer, tablet, and television use). We also found some support that the negative effects of morning depletion on daily work engagement may be buffered by job control, such that depletion impairs work engagement only for employees who experience low job control. 相似文献

Research in the area of personality traits and academic performance has been supported by consistent meta‐analytic evidence demonstrating positive relationships between Conscientiousness and grade point average (GPA). However, academic performance is not solely a function of GPA but also a number of other important intellectual, interpersonal and intrapersonal behaviours. This wider criterion space opens up the possibility for many personality factors and their underlying facets to relate to academic performance. Using bifactor latent variable modelling, the current study investigates the six‐factor HEXACO model of personality, along with their 24 underlying facets, for predicting students' academic performance. Model results reveal interpretable and meaningful relationships between both broad factors and narrow personality facets in predicting college student outcomes. Implications for measurement, modelling and prediction are discussed. Copyright © 2014 European Association of Personality Psychology 相似文献

The assessment of higher-education student learning outcomes is an important component in understanding the strengths and weaknesses of academic and general education programs. This study illustrates the application of diagnostic classification models, a burgeoning set of statistical models, in assessing student learning outcomes. To facilitate understanding and future applications of diagnostic modeling, the log-linear cognitive diagnosis model used in this study is presented in a didactic manner. The model is applied in a context where undergraduate students were assessed along four learning outcomes related to psychosocial research across two time points. Results focus on implications and methods to aid stakeholders’ interpretation of the analyses. Contrasts to traditional measurement models and potential future applications are also discussed. 相似文献

Assessments consisting of only a few extended constructed response items (essays) are not typically equated using anchor test designs as there are typically too few essay prompts in each form to allow for meaningful equating. This article explores the idea that output from an automated scoring program designed to measure writing fluency (a common objective of many writing prompts) can be used in place of a more traditional anchor. The linear-logistic equating method used in this article is a variant of the Tucker linear equating method appropriate for the limited score range typical of essays. The procedure is applied to historical data. Although the procedure only results in small improvements over identity equating (not equating prompts), it does produce a viable alternative, and a mechanism for checking that the identity equating is appropriate. This may be particularly useful for measuring rater drift or equating mixed format tests. 相似文献

The International Test Commission's Guidelines for Translating and Adapting Tests (2010) provide important guidance on developing and evaluating tests for use across languages. These guidelines are widely applauded, but the degree to which they are followed in practice is unknown. The objective of this study was to perform a systematic review of published articles to determine whether the methodologies related to test adaptation and evaluation of cross-lingual measurement bias have improved since the initial publication of the Guidelines. Results demonstrated that although reporting reliability estimates and statistically analyzing construct equivalence improved since publication of the Guidelines, the majority of test development and validation practices in the published literature have not embraced the recommendations put forth by the International Test Commission. Overall, these findings call into question many of the inferences derived from cross-linguistic comparisons and clearly signal a need for better dissemination mechanisms of the Guidelines. 相似文献

Cognitive failures are lapses in attention, cognition, and actions that everybody experiences in everyday life. Self-reports are mainly used for assessment but those instruments are memory-biased and more related to personality aspects than to actual behavior. Ambulatory assessment is already used for capturing emotions or addictive behavior, but not yet for cognitive failures. The newly developed Questionnaire for Cognitive Failures in Everyday Life (KFA) was applied via mobile phones (electronic KFA) wherein an acoustic signal asked participants (N = 91, 60–76 years) 4 times daily to answer 13 questions for 1 week. The new instrument showed satisfying reliability and was compared with a self-report method (Cognitive Failures Questionnaire; Broadbent, Cooper, Fitzgerald, and Parkes, 1982) in terms of correlations with cognitive abilities (working memory capacity, short-term memory, switching ability, and reasoning), personality traits, and demographical aspects. Although further validation is needed, first results are promising and eKFA enriches cognitive failures research. 相似文献

Despite considerable evidence that testing benefits subsequent retrieval of information, it remains uncertain whether this effect extends to topically related information with authentic classroom materials. In the current study we first profile the way in which quizzing is used in the classroom through a survey of introductory psychology instructors. The survey results indicate that, instructors frequently use related but different questions on quizzes and tests unlike many laboratory experiments that use identical questions. In two subsequent experiments, participants studied information from a college biology textbook, were quizzed twice, and given a final test. The items on the final test were either identical to or were related but different than the quiz items. Experiment 1 showed that testing produced the typical robust testing effect for repeated items, but there was no significant effect of testing for topically related items. In Experiment 2, participants could use their quizzes to guide restudy, and there was still no positive effect of testing for topically related information. 相似文献

Near-death experiences (NDEs) have become a topic of increasing interest to medical and psychological researchers over the last 35 years. During the course of this research agenda, several studies have focused on the phenomenology of the experience and its after-effects, mostly from a nomothetic stance. The aim of this study was to investigate the experience of having an NDE and what meaning NDErs attribute to that experience and its resultant after-effects by taking an idiographic, phenomenological approach. Three female participants took part in recorded face-to-face, semi-structured interviews. Interpretative Phenomenological Analysis found that to more deeply understand the impact of NDEs it is crucial to consider how the experience fits within the biographical context of an individual's life. Rather than being an overall influence on personal and spiritual growth, individuals may choose elements of an experience which are most personally meaningful for them and take that into their later lives. Each participant in some way came to a new understanding in their lives as a result of their NDE. In addition, the process of integration was helped or hindered by physical and psychological factors concomitant at the time of the NDE. Also evident were the challenges the NDE, or elements therein, have on the individual's sense of self and how they maintain and develop that self in the years succeeding the event. 相似文献
