The educational psychology literature is replete with references to higher-order cognitive constructs, such as critical thinking and creativity. Presumably, these constructs represent the primary processes and outcomes that educators should promote in students. For these constructs to be maximally useful, they must be transformed into specific operational definitions that lead to reliable and valid assessment strategies. Minimizing overlap in the definitions and assessment of different concepts would contribute to an orderly accumulation of knowledge about the constructs in question. The ideal would be for each construct to have a definition that is distinct from the definitions of other cognitive constructs. Although higher-order cognitive constructs have much surface appeal, their utility is tied to the clarity and fidelity of their definitions and assessment procedures.  相似文献

Multivariate analysis of variance (MANOVA) is widely used in educational research to compare means on multiple dependent variables across groups. Researchers faced with the problem of missing data often use multiple imputation of values in place of the missing observations. This study compares the performance of 2 methods for combining p values in the context of a MANOVA, with the typical default for dealing with missing data: listwise deletion. When data are missing at random, the new methods maintained the nominal Type I error rate and had power comparable to the complete data condition. When 40% of the data were missing completely at random, the Type I error rates for the new methods were inflated, but not for lower percents.  相似文献

The purpose of this simulation study was to assess the performance of latent variable models that take into account the complex sampling mechanism that often underlies data used in educational, psychological, and other social science research. Analyses were conducted using the multiple indicator multiple cause (MIMIC) model, which is a flexible and effective tool for relating observed and latent variables. The data were simulated in a hierarchical framework (e.g., individuals nested in schools) so that a multilevel modeling approach would be appropriate. Analyses were conducted accounting for and not accounting for the nested data to determine the impact of ignoring such multilevel data structures in full structural equation models. Results highlight the differences in modeling results when the analytic strategy is congruent with the data structure and what occurs when this congruency is absent. Type I error rates and power for the standard and multilevel methods were similar for within-cluster variables and for the multilevel model with between-cluster variables. However, Type I error rates were inflated for the standard approach when modeling between-cluster variables.  相似文献

Abstract

Researchers conducting structural equation modeling analyses rarely, if ever, control for the inflated probability of Type I errors when evaluating the statistical significance of multiple parameters in a model. In this study, the Type I error control, power and true model rates of famsilywise and false discovery rate controlling procedures were compared with rates when no multiplicity control was imposed. The results indicate that Type I error rates become severely inflated with no multiplicity control, but also that familywise error controlling procedures were extremely conservative and had very little power for detecting true relations. False discovery rate controlling procedures provided a compromise between no multiplicity control and strict familywise error control and with large sample sizes provided a high probability of making correct inferences regarding all the parameters in the model.  相似文献

The purpose of this article is to suggest future directions for research in educational psychology as we enter our second hundred years of psychology in America. The basic theme is that there are both continuities and discontinuities in our development from the early days of Hall, Thorndike, James, and Dewey to the current multiplicity of perspectives represented in educational psychology. Eight issues are presented that will guide future research directions. They include. (a) specifying basic constructs; (b) developing integrative models and linkages between constructs; (c) returning to the problems of acquisition, learning, and transfer; (d) applying models from the sciences and mathematics; (e) dealing with the discontinuity of contextual and cultural models; (0 including content and disciplinary perspectives; (g) adapting to diversity; and (h) developing multiple perspectives an the unit of analysis issue. The article concludes with a call for the allowance of multiple perspectives and multiple possible selves for educational psychologists while maintaining a commitment to psychological models and the improvement of education.  相似文献

This article used the Wald test to evaluate the item‐level fit of a saturated cognitive diagnosis model (CDM) relative to the fits of the reduced models it subsumes. A simulation study was carried out to examine the Type I error and power of the Wald test in the context of the G‐DINA model. Results show that when the sample size is small and a larger number of attributes are required, the Type I error rate of the Wald test for the DINA and DINO models can be higher than the nominal significance levels, while the Type I error rate of the A‐CDM is closer to the nominal significance levels. However, with larger sample sizes, the Type I error rates for the three models are closer to the nominal significance levels. In addition, the Wald test has excellent statistical power to detect when the true underlying model is none of the reduced models examined even for relatively small sample sizes. The performance of the Wald test was also examined with real data. With an increasing number of CDMs from which to choose, this article provides an important contribution toward advancing the use of CDMs in practical educational settings.  相似文献

The relationship between psychology and education may be expressed in terms of two general models: the traditional hierarchical model, according to which psychology is the “parent” discipline; and a parallel model, in which the relationship between “pure” theory and its application is metaphoric rather than paradigmatic. The hierarchical model, however, does not hold even for such a “tight” area as behavior modification, let alone for educational practice in general.Educational practice, as a professional enterprise, should be guided by a consistent set of constructs taken from the practitioner's universe of discourse. The professionalization of education has been delayed because of attempts, mostly vain, to guide practice by applying constructs derived from other disciplines. Other disciplines, notably psychology, can be useful for education but in a metaphoric sense only. “Educology” is suggested as a convenient term for the set of constructs that should give coherence to educational decision-making.  相似文献

This Monte Carlo simulation study investigated the impact of nonnormality on estimating and testing mediated effects with the parallel process latent growth model and 3 popular methods for testing the mediated effect (i.e., Sobel’s test, the asymmetric confidence limits, and the bias-corrected bootstrap). It was found that nonnormality had little effect on the estimates of the mediated effect, standard errors, empirical Type I error, and power rates in most conditions. In terms of empirical Type I error and power rates, the bias-corrected bootstrap performed best. Sobel’s test produced very conservative Type I error rates when the estimated mediated effect and standard error had a relationship, but when the relationship was weak or did not exist, the Type I error was closer to the nominal .05 value.  相似文献

Measurement of principal implementation behaviors has proved difficult to researchers in educational leadership due to a lack of consensus on the operational definitions of leadership constructs. The Principal Implementation Questionnaire (PIQ) was developed and validated with the intention of providing clarity in the assessment of principal leadership behaviors in the implementation of effective reading programs. Constructs were operationally defined within the context of the population of interest, with subsequent item writing centered around the constructs. A resulting calibration sample of principals from Florida Reading First schools was used to test the hypothesized measurement model to determine how well the items were described by the proposed factors. Results from LISREL analyses revealed a well-fitted model, based on numerous fit indices.  相似文献

The standardized log-likelihood of a response vector (lz) is a popular IRT-based person-fit test statistic for identifying model-misfitting response patterns. Traditional use of lz is overly conservative in detecting aberrance due to its incorrect assumption regarding its theoretical null distribution. This study proposes a method for improving the accuracy of person-fit analysis using lz which takes into account test unreliability when estimating the ability and constructs the distribution for each lz through resampling methods. The Type I error and power (or detection rate) of the proposed method were examined at different test lengths, ability levels, and nominal α levels along with other methods, and power to detect three types of aberrance—cheating, lack of motivation, and speeding—was considered. Results indicate that the proposed method is a viable and promising approach. It has Type I error rates close to the nominal value for most ability levels and reasonably good power.  相似文献

The purpose of this article is to define formative assessment, outline what is known about the prevalence of formative assessment implementation in the classroom, establish the importance of formative assessment with regards to student motivation and achievement, and present the results of a content analysis of current educational psychology textbooks. Several key definitions of formative assessment are examined, and various means of conducting formative assessment are outlined. Numerous studies that have examined the effects of formative assessment on motivation and achievement are summarized. The theoretical link between formative assessment and several important motivational constructs is established, and suggestions for future research are delineated.  相似文献

The utility of Orlando and Thissen’s (2000, 2003) S-X2 fit index was extended to the model-fit analysis of the graded response model (GRM). The performance of a modified S-X2 in assessing item-fit of the GRM was investigated in light of empirical Type I error rates and power with a simulation study having various conditions typically encountered in applied testing situations. The results show that the Type I error rates were controlled adequately around the nominal alpha by S-X2. The power of the S-X2 statistic was much lower when the source of misfit was multidimensionality than when it was due to discrepancy from the true GRM curves. Once the data size increased sufficiently, however, appropriate power was obtained regardless of the source of the item-misfit. In summary, the generalized S-X2 appears to be a promising index for investigating item fit for polytomous items in educational and psychological assessments.  相似文献

When structural equation modeling (SEM) analyses are conducted, significance tests for all important model relationships (parameters including factor loadings, covariances, etc.) are typically conducted at a specified nominal Type I error rate (α). Despite the fact that many significance tests are often conducted in SEM, rarely is multiplicity control applied. Cribbie (2000, 2007) demonstrated that without some form of adjustment, the familywise Type I error rate can become severely inflated. Cribbie also confirmed that the popular Bonferroni method was overly conservative due to the correlations among the parameters in the model. The purpose of this study was to compare the Type I error rates and per-parameter power of traditional multiplicity strategies with those of adjusted Bonferroni procedures that incorporate not only the number of tests in a family, but also the degree of correlation between parameters. The adjusted Bonferroni procedures were found to produce per-parameter power rates higher than the original Bonferroni procedure without inflating the familywise error rate.  相似文献

In this article, we question why race as a sociohistorical construct has not traditionally been investigated in educational psychology research. To do so, we provide a historical discussion of the significance of race as well as present current dilemmas in the exploration of race, including an examination of the incidence and prevalence of race-related constructs in top educational psychology journals. As a means of expanding educational psychology's use of race as a sociohistorical construct, we introduce the concepts of race-focused and race-reimaged constructs. We end the article with suggestions for how we can begin exploring race as a sociohistorical construct in the field of educational psychology, including the need to challenge traditional paradigms and embrace culturally relevant methodologies.  相似文献

Despite increasing racial and cultural diversity in the United States and many other industrialized countries, less than 2% of research published in top-tier educational psychology journals authentically examines the experiences of racial and cultural minorities. Through this special issue, we not only aim to increase representation of these populations in our research, but we also strive to promote greater integrity in how racial and cultural constructs are managed in the theories, methods, analyses, and interpretations of educational psychology research. In this introduction article, we define and discuss race-reimaging in educational psychology. Further, we briefly review the historical and contemporary issues in conventional psychological research that necessitate race-reimaging and underscore its appeal. Subsequently, we introduce each article in the special issue and speak to how its respective race-reimaging qualities inform as well as extend traditional educational psychology constructs. Finally, we point to special guest commentary by Paul Schutz and conclude with implications for race-reimaged research broadly.  相似文献

This study examined the effect of sample size ratio and model misfit on the Type I error rates and power of the Difficulty Parameter Differences procedure using Winsteps. A unidimensional 30-item test with responses from 130,000 examinees was simulated and four independent variables were manipulated: sample size ratio (20/100/250/500/1000); model fit/misfit (1 PL and 3PLc =. 15 models); impact (no difference/mean differences/variance differences/mean and variance differences); and percentage of items with uniform and nonuniform DIF (0%/10%/20%). In general, the results indicate the importance of ensuring model fit to achieve greater control of Type I error and adequate statistical power. The manipulated variables produced inflated Type I error rates, which were well controlled when a measure of DIF magnitude was applied. Sample size ratio also had an effect on the power of the procedure. The paper discusses the practical implications of these results.  相似文献

Byrnes and Fox (1998) present the case for the relevance of cognitive neuroscience in educational psychology, including both logical and empirical arguments. In this commentary, I begin by briefly reviewing the history of the case for including the brain in educational psychology: Early educational psychology—as reflected in Thorndike's (1926) educational psychology textbook—emphasized the neuronal basis of learning; contemporary educational psychology—as reflected in educational publications—tends to ignore the brain; and future educational psychology will need to overcome the pitfalls encountered in previous misuses of brain research. Next, I examine two logical arguments for Byrnes and Fox's case, namely, that including cognitive neuroscience research makes educational psychology more complete and more plausible. Then, I examine the empirical argument of Byrnes and Fox by focusing on the value of cognitive neuroscience research in attention and memory as well as in reading and arithmetic. Finally, I suggest criteria for evaluating the contributions of cognitive neuroscience research in educational psychology, including the need for research on educationally relevant tasks and issues.  相似文献

Cognitive scientists have suggested that individual differences are relatively unimportant in predicting who will become an expert in any particular domain. This stance is at variance with the admissions screening practices of graduate programs in professional psychology as well as with counseling psychology's individual differences tradition. The purpose of this article was to consider some of the issues involved on both sides of this apparent contradiction, with particular emphasis on expertise in professional psychology. I first examine some of the possible operational definitions of expertise in this domain. I then consider salient literature and conclude that there almost certainly are threshold levels of intellectual and interpersonal skills that trainees in professional psychology should have. Beyond these levels, though, it may be that motivation and persistence are the most important variables in predicting the eventual attainment of expertise in professional psychology.  相似文献
