Expectancy-value researchers have described the components of subjective task value in multiple ways, leading to multiple competing structural representations of subjective task value data. The purpose of this study was to examine these competing multidimensional factor structures by comparing correlated factor, hierarchical, and bifactor representations of both confirmatory factor analysis and exploratory structural equation modeling (ESEM) models across three theoretical conceptualizations of subjective task value. Results indicate that, in an undergraduate life science learning context (n = 334), the best representation for subjective task value data was a bifactor ESEM model that allowed for the disentangling of general and specific variance of general subjective task value, specific value beliefs, and specific costs. Full measurement invariance of the retained structure across continuing generation and first-generation students was found, and no differential item functioning was found across gender. General subjective task value and specific opportunity cost significantly and positively predicted achievement and specific utility value significantly and negatively predicted achievement, providing support for the criterion-related validity of the general and specific factors for predicting achievement outcomes.  相似文献

Despite a growing interest in instructional feedback, students’ feedback perceptions received limited attention. We examined the structural validity and measurement invariance of the Feedback Perceptions Questionnaire (FPQ). The FPQ measures feedback perceptions in terms of perceived fairness, usefulness, acceptance, willingness to improve, and affect. Secondary school students (N = 1486) received a fictional scenario containing Concise General Feedback or Elaborated Specific Feedback by a fictional peer. Students rated their perceptions as if they had received the feedback themselves. Confirmatory Factor Analysis (CFA) supports the structural validity of the FPQ and its invariance for the two types of peer feedback, gender, four grade-levels and two tracks. Perceived fairness of peer feedback was a strong positive predictor of willingness to improve and affect, whereas perceived usefulness and acceptance of peer feedback showed a more complex pattern in predicting willingness to improve and affect.  相似文献

Females are known to excel over males in most reading tasks, but notconsistently so in tasks that require processing information from maps,tables, charts and diagrams, so called `Documents'. The IEA ReadingLiteracy data provides possibilities to investigate gender differencesacross countries in such tasks in two age groups, 9-year-olds and14-year-olds. The general question about cultural influences vs. aninvariant pattern of gender differences is of great interest for genderresearch, and central in this study. The aim of the paper is to describeand analyze gender differences on Document tasks, and investigate if andhow the pattern of differences varies over countries. Another aim is todemonstrate the power of using a multivariate analysis technique bycontrasting it against traditional univariate approaches. The univariateanalysis indicates female advantage as the most common in the youngergroup and a mixed pattern in the older. The multivariate analysisindicate that Document tasks are not unidimensional, because bothgeneral and specific dimensions can be extracted from the raw scores.The traditional univariate analysis often disguised true patterns ofdifferences in the data, both in terms of country differences and interms of the direction of the gender differences. Raw score differencesbetween the genders proved to be due to differences in both general andpassage specific dimensions. Ten of the countries showed genderdifferences in both directions in the general dimension among9-year-olds, while an almost consistent pattern of female advantage wasfound among 14-years-olds. Many of the specific passage dimensionsturned out to favor either males or females. This complex pattern variedover both age groups and across countries, although commonalities in thepattern among subgroups of countries were common.  相似文献

Multigroup exploratory factor analysis (EFA) has gained popularity to address measurement invariance for two reasons. Firstly, repeatedly respecifying confirmatory factor analysis (CFA) models strongly capitalizes on chance and using EFA as a precursor works better. Secondly, the fixed zero loadings of CFA are often too restrictive. In multigroup EFA, factor loading invariance is rejected if the fit decreases significantly when fixing the loadings to be equal across groups. To locate the precise factor loading non-invariances by means of hypothesis testing, the factors’ rotational freedom needs to be resolved per group. In the literature, a solution exists for identifying optimal rotations for one group or invariant loadings across groups. Building on this, we present multigroup factor rotation (MGFR) for identifying loading non-invariances. Specifically, MGFR rotates group-specific loadings both to simple structure and between-group agreement, while disentangling loading differences from differences in the structural model (i.e., factor (co)variances).  相似文献

The present study examined the components of end of kindergarten writing, using data from 242 kindergartners. Specifically of interest was the importance of spelling, letter writing fluency, reading, and word- and syntax-level oral language skills in writing. The results from structural equation modeling revealed that oral language, spelling, and letter writing fluency were positively and uniquely related to writing skill after accounting for reading skills. Reading skill was not uniquely related to writing once oral language, spelling, and letter writing fluency were taken into account. These findings are discussed from a developmental perspective.  相似文献

The models presented here posit a complex relationship between efficacy in student engagement and intent-to-leave that is mediated by in-class variables of instructional management, student behavior stressors, aspects of burnout, and job satisfaction. Using data collected from 631 teachers, analyses provided support for the two models that predicted teachers' intent-to-leave. To enhance generalizability, this study also tested whether the structural coefficients were invariant across teacher gender and grade level. With one exception, the models appeared largely invariant across gender and grade level. Supplementing the structural models, measurement invariance and equality of latent factor means were also explored.  相似文献

Difficulties arise in multiple-group evaluations of factorial invariance if particular manifest variables are missing completely in certain groups. Ad hoc analytic alternatives can be used in such situations (e.g., deleting manifest variables), but some common approaches, such as multiple imputation, are not viable. At least 3 solutions to this problem are viable: analyzing differing sets of variables across groups, using pattern mixture approaches, and a new method using random number generation. The latter solution, proposed in this article, is to generate pseudo-random normal deviates for all observations for manifest variables that are missing completely in a given sample and then to specify multiple-group models in a way that respects the random nature of these values. An empirical example is presented in detail comparing the 3 approaches. The proposed solution can enable quantitative comparisons at the latent variable level between groups using programs that require the same number of manifest variables in each group.  相似文献

According to the simple view of reading (SVR), reading comprehension relies on “decoding” (pseudoword, word reading) and “oral comprehension” skills. Testing 556 French pupils, we aimed at unpacking these two components and tracking their longitudinal development in first grade. We have found that: (1) lower level language skills (vocabulary, syntax) and discourse skills (oral text comprehension) emerged as two dimensions of “oral comprehension”; (2) lower level language skills longitudinally predicted reading comprehension outcomes, above code-related skills; (3) decoding precursors (letter knowledge, naming speed and phonemic awareness) predicted reading comprehension directly, and indirectly, through decoding skills (pseudoword, word reading, text reading fluency); (4) Oral comprehension skills did not favour the development of decoding. Our results support the independency of the SVR components. However, we suggest that a more fine-grained conceptualisation of oral comprehension skills would help to better understand the individual and pedagogical factors influencing the early development of reading comprehension.  相似文献

This paper investigates the importance of parents reading to their young children. Using Australian data we find that parental reading to children at age 4–5 has positive and significant effects on reading skills and cognitive skills (including numeracy skills) of these children at least up to age 10 or 11. The effects on skills more closely related to reading and language are larger than those on skills such as numeracy skills. However, all findings in relation to reading and other cognitive skills are persistent and robust to a wide range of sensitivity analyses. Although reading to children is also correlated with children's non-cognitive skills, after accounting for the endogeneity of reading to children, no causal effect remains.  相似文献

We present a multigroup multilevel confirmatory factor analysis (CFA) model and a procedure for testing multilevel factorial invariance in n-level structural equation modeling (nSEM). Multigroup multilevel CFA introduces a complexity when the group membership at the lower level intersects the clustered structure, because the observations in different groups but in the same cluster are not independent of one another. nSEM provides a framework in which the multigroup multilevel data structure is represented with the dependency between groups at the lower level properly taken into account. The procedure for testing multilevel factorial invariance is illustrated with an empirical example using an R package xxm2.  相似文献

Common factor analysis (FA) and principal component analysis (PCA) are commonly used to obtain lower-dimensional representations of matrices of correlations among manifest variables. Whereas some experts argue that differences in results from use of FA and PCA are small and relatively unimportant in empirical studies, the fundamental rationales for the two methods are very different. Here, FA and PCA are contrasted on four key issues: the range of possible dimensional loadings, the range of potential correlations among dimensions, the structure of residual covariances and correlations, and the relation between population parameters and the correlational structures with which they are associated. For decades, experts have emphasized indeterminacies of the FA model, particularly indeterminacy of common factor scores. Determinate in most respects, a heretofore unacknowledged, pernicious indeterminacy of PCA is demonstrated: the indeterminacy between PCA structural representations and the correlational structures from which they are derived. Researchers are often advised to use either FA or PCA in exploratory rounds of data analysis to understand and refine the dimensional structure of a domain before moving to Structural Equation Modeling in later theory-testing, confirmatory, replication studies. Results from the current study suggest that PCA is an unreliable method to use for such purposes and may lead to serious misrepresentation of the structure of a domain. Hence, PCA should never be used if the goal is to understand and represent the latent structure of a domain; only FA techniques should be used for this purpose, as only FA provides reliable structural representations as the basis for confirmatory tests in future studies.  相似文献

Measurement bias can be detected using structural equation modeling (SEM), by testing measurement invariance with multigroup factor analysis (Jöreskog, 1971;Meredith, 1993;Sörbom, 1974) MIMIC modeling (Muthén, 1989) or restricted factor analysis (Oort, 1992,1998). In educational research, data often have a nested, multilevel structure, for example when data are collected from children in classrooms. Multilevel structures might complicate measurement bias research. In 2-level data, the potentially “biasing trait” or “violator” can be a Level 1 variable (e.g., pupil sex), or a Level 2 variable (e.g., teacher sex). One can also test measurement invariance with respect to the clustering variable (e.g., classroom). This article provides a stepwise approach for the detection of measurement bias with respect to these 3 types of violators. This approach works from Level 1 upward, so the final model accounts for all bias and substantive findings at both levels. The 5 proposed steps are illustrated with data of teacher–child relationships.  相似文献

Abstract

This article examines the impact of the reading assessment, DIBELS (Dynamic Indicators of Basic Early Literacy Skills), on literacy education through the Habermasian lens. It argues that DIBELS, along with other systemic forces, has surged beyond its domain as a mere assessment and colonized the lifeworld of literacy education by distorting the meaning of the teaching and learning of literacy.This article calls for a critical reflection on the systemized practices in literacy education and for a return to a lifeworld where literacy is considered more than a testable skill.  相似文献

To infer longitudinal relationships among latent factors, traditional analyses assume that the measurement model is invariant across measurement occasions. Alternative to placing cross-occasion equality constraints on parameters, approximate measurement invariance (MI) can be analyzed by specifying informative priors on parameter differences between occasions. This study evaluated the estimation of structural coefficients in multiple-indicator autoregressive cross-lagged models under various conditions of approximate MI using Bayesian structural equation modeling. Design factors included factor structures, conditions of non-invariance, sizes of structural coefficients, and sample sizes. Models were analyzed using two sets of small-variance priors on select model parameters. Results showed that autoregressive coefficient estimates were more accurate for the mixed pattern than the decreasing pattern of non-invariance. When a model included cross-loadings, an interaction was found between the cross-lagged estimates and the non-invariance conditions. Implications of findings and future research directions are discussed.  相似文献

The computerization of reading assessments has presented a set of new challenges to test designers. From the vantage point of measurement invariance, test designers must investigate whether the traditionally recognized causes for violating invariance are still a concern in computer-mediated assessments. In addition, it is necessary to understand the technology-related causes of measurement invariance among test-taking populations. In this study, we used the available data (n = 800) from the previous administrations of the Pearson Test of English Academic (PTE Academic) reading, an international test of English comprising 10 test items, to investigate measurement invariance across gender and the Information and Communication Technology Development index (IDI). We conducted a multi-group confirmatory factor analysis (CFA) to assess invariance at four levels: configural, metric, scalar, and structural. Overall, we were able to confirm structural invariance for the PTE Academic, which is a necessary condition for conducting fair assessments. Implications for computer-based education and the assessment of reading are discussed.  相似文献
