多媒体环境中动机、意志和成绩的整合理论   总被引：7，自引：0，他引：7  

约翰M·凯勒  孟万金  张晓光 《教育研究》2006,(10)

动机、意志和成绩的整合理论(MVP)在宏观动机模式ARCS(Attention,Relevence,Confidence,Satisfaction)基础上发展而成,它囊括了动机意志模式中动机和行为的各个行动阶段——从目标确定到意志行动再到目标实现,有效地解释了从愿望到行动的进程。MVP还吸纳了行动控制理论、动机意志模式、阿斯特累特纳和威斯纳的多媒体与动机整合模式以及迈耶的多媒体学习理论中的合理成分,使动机加工成分得到了重新定位和补充,因而与ARCS相比,MVP更有利于综合地解释动机、意志、学习和成绩之间的复杂关系,更有利于进一步支持有关的理论构建、经验研究以及使用策略的开发与验证。  相似文献   

R‐CBM IN SPANISH AND IN ENGLISH: DIFFERENTIAL RELATIONS DEPENDING ON STUDENT READING PERFORMANCE     

Milena A. Keller‐Margulis  Sterett H. Mercer 《Psychology in the schools》2014,51(7):677-692

This study investigated how performance on reading curriculum‐based measurement (R‐CBM) in Spanish is related to performance on R‐CBM in English. Parallel process growth models and quantile regression analyses were used to examine the relations between initial benchmark scores and growth and the consistency of the relations across student reading skill levels. Initial benchmark scores and growth were strongly related across languages in most grades, and initial scores were less strongly related for students with low and high reading achievement, as measured by curriculum‐based measurement in most grades. Rates of growth were evenly related across performance in fourth and fifth grades, but less strongly related for high‐achieving students in second and third grades. Practical implications and future directions are discussed.  相似文献   

Predicting long-term outcomes for women sexually abused in childhood: contribution of abuse severity versus family environment     

Fassler IR  Amodeo M  Griffin ML  Clay CM  Ellis MA 《Child abuse & neglect》2005,29(3):269-284

OBJECTIVE: Child sexual abuse (CSA) has been associated with adverse adult psychosocial outcomes, although some reports describe minimal long-term effects. The search for explanations for the heterogeneous outcomes in women with CSA has led to an examination of a range of CSA-related factors, from the severity of individual CSA incidents to the childhood family environment. This study compares three factors for predicting adult outcomes: a multidimensional CSA Severity Scale, the presence or absence of CSA, and family environment. METHODS: The effect of CSA on adult outcomes was examined among 290 community-dwelling women raised in intact families. Standardized measures and a focused interview were used to collect data, with siblings as collateral informants. RESULTS: Comparison of a multidimensional CSA Severity Scale to a dichotomous measure of the presence or absence of CSA showed that the Severity Scale did not have greater predictive value for adult outcomes than the dichotomous measure, nor was it as parsimonious. Childhood family environment scales added significantly to the predictive ability of the dichotomous measure. CONCLUSION: The specific characteristics of a CSA experience may be less important than the occurrence of CSA and the family environment of women for predicting long-term outcomes.  相似文献

Sticky assessments – the impact of teachers’ grading standard on pupils’ school performance     

Tamás Keller 《Educational studies》2016,42(5):493-518

This paper argues that school grades cannot be interpreted solely as a reward for a given school performance, since they also reflect teachers’ assessments of pupils. A teacher’s evaluation of a pupil’s performance, as reflected in the grade awarded, might influence the effort that the pupil invests in learning. Grades might therefore serve as sticky assessments, affecting pupils’ later school performance. Getting discounted grades in year 6 for a given level of maths performance assessed using a PISA-like test has a positive effect on maths test scores in year 8 of elementary education, and also influences later outcomes in secondary education. The empirical analysis tries to minimise the possible bias caused by measurement error in year 6 test scores (unmeasured ability) and employs classroom fixed-effect instrumental variable (IV) regression and difference-in-difference models. The empirical analysis is based on a unique Hungarian individual-level panel data-set containing two observations about the same individual – one in year 6 (12/13 years old) and the other two years later, in year 8 (14/15 years old) of elementary education. The data for three entire school cohorts is analysed – approximately 140,000 individuals.  相似文献   

The Development of Implicit Memory From Infancy to Childhood: On Average Performance Levels and Interindividual Differences          下载免费PDF全文

Isabel A. Vöhringer  Thorsten Kolling  Frauke Graf  Sonja Poloczek  Ina Fassbender  Claudia Freitag  Bettina Lamm  Janina Suhrke  Johanna Teiser  Manuel Teubert  Heidi Keller  Arnold Lohaus  Gudrun Schwarzer  Monika Knopf 《Child development》2018,89(2):370-382

The present multimethod longitudinal study aimed at investigating development and stability of implicit memory during infancy and early childhood. A total of 134 children were followed longitudinally from 3 months to 3 years of life assessing different age‐appropriate measures of implicit memory. Results from structural equation modeling give further evidence that implicit memory is stable from 9 months of life on, with earlier performance predicting later performance. Second, it was found that implicit memory is present from early on, and no age‐related improvements are found from 3 months on. Results are discussed with respect to the basic brain structures implicit memory builds on, as well as methodological issues.  相似文献   

The MSU Educational Technology Certificate Courses and Their Impact on Teachers’ Growth as Technology Integrators     

Michelle Schira Hagerman  Alison Keller  Jodi L. Spicer 《TechTrends》2013,57(3):26-33

The Educational Technology Certificate (ETC.) courses at Michigan State University are a set of three courses that can be taken as a standalone qualification or as the first three courses in the Master’s of Educational Technology degree. Together, the courses emphasize the development of technology skills and advanced mindsets for technology integration in the classroom. In this article, we provide examples of our approach to the teaching of technology skills and mindsets in ways that are adaptable across four distinct modes of instruction (online, hybrid, overseas and faceto-face). We also present student feedback and survey data that inform a critical evaluation of the program’s effectiveness. Findings suggest that the certificate courses help students to gain technological skills, to become more confident users of technology and more likely to help colleagues with tech-related questions. Interestingly, respondents also reported feeling like better teachers, in general, after taking these courses.  相似文献   

A Note on Cluster Effects in Latent Class Analysis     

David Kaplan  Bryan Keller 《Structural equation modeling》2013,20(4):525-536

This article examines the effects of clustering in latent class analysis. A comprehensive simulation study is conducted, which begins by specifying a true multilevel latent class model with varying within- and between-cluster sample sizes, varying latent class proportions, and varying intraclass correlations. These models are then estimated under the assumption of a single-level latent class model. The outcomes of interest are measures of bias in the Bayesian Information Criterion (BIC) and the entropy R ² statistic relative to accounting for the multilevel structure of the data. The results indicate that the size of the intraclass correlation as well as between- and within-cluster sizes are the most prominent factors in determining the amount of bias in these outcome measures, with increasing intraclass correlations combined with small between-cluster sizes resulting in increased bias. Bias is particularly noticeable in the BIC. In addition, there is evidence that class separation interacts with the size of the intraclass correlations and cluster sizes in producing bias in these measures.  相似文献   

The Long‐Term Sustainability of IRT Scaling Methods in Mixed‐Format Tests     

Lisa A. Keller  Ronald K. Hambleton 《Journal of Educational Measurement》2013,50(4):390-407

Due to recent research in equating methodologies indicating that some methods may be more susceptible to the accumulation of equating error over multiple administrations, the sustainability of several item response theory methods of equating over time was investigated. In particular, the paper is focused on two equating methodologies: fixed common item parameter scaling (with two variations, FCIP‐1 and FCIP‐2) and the Stocking and Lord characteristic curve scaling technique in the presence of nonequivalent groups. Results indicated that the improvements made to fixed common item parameter scaling in the FCIP‐2 method were sustained over time. FCIP‐2 and Stocking and Lord characteristic curve scaling performed similarly in many instances and produced more accurate results than FCIP‐1. The relative performance of FCIP‐2 and Stocking and Lord characteristic curve scaling depended on the nature of the change in the ability distribution: Stocking and Lord characteristic curve scaling captured the change in the distribution more accurately than FCIP‐2 when the change was different across the ability distribution; FCIP‐2 captured the changes more accurately when the change was consistent across the ability distribution.  相似文献
