In student-evaluation research, there has been considerable debate on the number of higher order factors in student ratings of university teaching. Using a distance learning program as the context for research, the study described in this article applied structural equation modeling to investigate the 2nd-order factor structure in student ratings of teaching effectiveness. An a priori model was hypothesized, which consisted of four 1st-order factors and one 2nd-order factor. Data were collected from 2,021 distance students using a multifactor questionnaire. In contrast to all past studies, the presence of a single 2nd-order factor in student ratings was empirically demonstrated through hierarchical confirmatory factor analysis. Implications for future research on the higher order factor structure in student ratings of conventional on-campus courses are also discussed.  相似文献

Teacher beliefs about curriculum design affect the quality of science education in schools, but science researchers know little about the interrelation of beliefs about alternative curriculum designs. This article describes a quantitative study of secondary science teachers' beliefs about curriculum design. A 33-item Science Curriculum Orientation Inventory (SCOI) was developed to measure five distinct orientations to curriculum: academic, cognitive processes, societycentred, humanistic, and technological. Data were collected from 810 integrated science, chemistry, physics, and biology teachers in Hong Kong. A confirmatory factor analysis of teacher responses to the SCOI indicated that science teachers' beliefs about curriculum design had a hierarchical structure; the five distinct curriculum orientations were positively correlated, forming a second-order curriculum, meta-orientation. Physics teachers were less society-oriented than biology, integrated science and chemistry teachers, and integrated science teachers were more humanistic than physics teachers. Although science teachers' beliefs about any of the five alternative curriculum designs did not vary with their teaching experience, the difference between beliefs about the cognitive processes orientation and the humanistic orientation increased when teachers had gained more teaching experience. Implications of these findings are discussed.  相似文献

Ipsative data (individual scores subject to a constant-sum constraint), suggested to minimize response bias, are sometimes observed in behavioral sciences. Chan and Bentler (1993, 1996) proposed a method to analyze ipsative data in a single-group case. Cheung and Chan (2002) extended the method to multiple-group analysis. However, these methods require tedious procedures on formulating within- and between-group constraints and recovering the parameter estimates and their standard errors. A direct estimation method, which is equivalent to Chan and Bentler's method with an alternative model specification, is proposed in this article. The 1st-order factor-analytic ipsative model in Chan and Bentler's method is reparameterized as a restricted 2nd-order factor-analytic model with fixed factor loading matrix reflecting the ipsative properties in the direct estimation method. The direct estimation method can be easily extended to test measurement invariance properties in multiple-group analysis. Issues related to ipsative models are also addressed.  相似文献

A confirmatory factor analysis was conducted to examine the structural validity of Daidalos, a 20‐item inventory designed to assess the factors that might inhibit or promote successful career decision making, or career maturity. The sample consisted of 776 high school students; 367 were male and 409 were female. Participants ranged in age from 16 to 54 years (M = 18). Goodness‐of‐fit statistics provided strong support for a two‐factor hierarchical model and slightly less for a five‐factor non‐hierarchical model. The two higher‐order factors were identified as a Pre‐process and a Process latent construct. Separate analysis for men and women showed that the model was far more appropriate for women than for men. Item loadings ranged from .46 to .81, first‐order factor intercorrelations ranged from ?.15 to .68, and the correlation between the two higher‐order factors was ?.42.  相似文献

Quantitative literacy (QLT) represents an underlying higher-order construct that accounts for a person's willingness to engage in quantitative situations in everyday life. The purpose of this study is to retest the construct validity of a model of quantitative literacy (Wilkins, 2010). In this model, QLT represents a second-order factor that accounts for the interrelationship among three first-order factors: mathematical beliefs, mathematical disposition, and mathematical cognition. Using data from two samples of undergraduate students (n = 186 and n = 184), a series of confirmatory factor analyses were conducted. Results supported the hierarchical three-factor structure and confirmed its factorial invariance across multiple groups of students. Latent QLT scores from the model were used to compare and rank student QLT by gender and class standing.  相似文献

The purpose of this study was to verify, through the application of confirmatory factor analysis, Guilford's formulation of social intelligence as a multidimensional concept. O'Sullivan, Guildford and Demille (1965), using exploratory factor analysis, found six factors of cognitive social intelligence. Using LISREL, we reanalyzed their data and tested two distinctly different factor models: (1a) the orthogonal six‐factor model proposed by O'Sullivan et al., (1b) the same six‐factor model except that the factors were allowed to intercorrelate, and (2) a single‐factor model. The orthogonal six‐factor model did not fit the data and, although the oblique variant of this model was an improvement, the single‐factor model fitted the data better in addition to being more parsimonious. This suggests that Guilford's concept of social intelligence is unnecessarily complicated and exposes a weakness in his Structure of Intellect Model. On the positive side, measurement of cognitive social intelligence should be more straightforward and our findings indicate which of Guilford's recommended tests are the best to use.  相似文献

Although curriculum orientations are widely discussed in educational literature, the extent to which teachers and other educational specialists in the United States hold these curriculum orientations is neither well documented nor well known. The relationships between a teacher's beliefs and the five dominant curriculum orientations (Academic Rationalism, Behavioural, Humanistic, Social Reconstruction and Cognitive Process) are unclear. Therefore, it is difficult to discuss the nature of how these curriculum orientations influence teacher choices and their execution and implementation of educational policy. This study replicated the 2002 research of Cheung and Wong in Hong Kong. A sample of 308 teachers in the United States participated. Findings indicate that the reliability and validity of the data were weak to moderate, and gender, level, subject speciality and experience influence a teacher's value of the particular curriculum orientations. The research also indicates that the construct of complementary pluralism (a strong positive relationship between the orientations of an individual teacher) does not exist with the same level of intensity for teachers in the United States. Rather, the theoretical opposition of the curriculum orientations is a practical opposition.  相似文献

A validation study was conducted on the Child Sex Abuse Attitude Scale (CSAAS) using confirmatory factor analysis (CFA) to examine factor structure. The CSAAS was developed based on Festinger's (1957) theory of attitude development resulting in a 4‐factor first‐order structure (cognition, value, affect, and behavior) and a single‐factor 2nd‐order structure (attitude). A sample of 215 school psychologists, members of the National Association of School Psychologists, responded to the CSAAS survey. CFA results supported the hypothesized factor structure of the CSAAS, thus indicating the plausibility of a 4‐factor 1st‐order and a single‐factor higher order structure of the CSAAS.  相似文献

This study measured and applied Senge ’s (1990) fifth discipline model of learning organizations in a culturally distinct population, namely teachers in 17 vocational high schools located in the Seoul megalopolis. The participants were 976 full-time vocational and academic teachers in public trade/industry-technical and business high schools in the Seoul megalopolis. Exploratory factor analysis was used to examine responses from Korean vocational high school teachers to questionnaire items designed to test the theoretical constructs and indices of Senge ’s learning organization model to establish a measurement model. The hypothesized model was tested using confirmatory factor analysis. Strong evidence was provided for the construct validity of the measurement model (i.e., instrument) to measure the learning organization concept in school contexts. The results also support the notion that the theory of learning organization and related concepts, initially developed against the background of Western culture, can apply to a South Korean school context, reflecting Asian culture.  相似文献

In this research, the authors raised the issue that prior studies had failed to address the nested structure of data in examining the construct validity of an instrument measuring students' behavioral and emotional participation in academic activities in the classroom. To address this question, the authors illustrated the utility of the multilevel confirmatory factor analysis (MCFA) approach to reexamine the construct validity of this instrument. The sample consisted of 2,041 students in 5th grade from 67 classes in Hong Kong. First, the results justified the requirement of MCFA and indicated that the 4-factor model tested with MCFA provided better fit to the data than that tested with a single-level confirmatory factor analysis (CFA). Second, the study also provided adequate support for a multilevel second-order two-factor model that distinguished engagement from disaffection. Third, the factor structure was invariant across the student level and the classroom level for both the 4-factor model and the second-order two-factor model. Fourth, the results highlighted the presence of ambiguity in differentiating between the dimensions at the classroom level and supported the unidimensionality of the classroom-level construct. Fifth, student engagement was significantly and positively correlated with mathematics test scores, teachers' classroom-management practices, teacher support, and student order in the classroom. Finally, the authors discuss the implications of the study and its limitations and offer suggestions for model selection and explorations for future research.  相似文献

The factor structure for the Wechsler Intelligence Scale for Children-Revised (WISC-R) was investigated for White (n = 183), Mexican American (n = 129), and African American (n = 139) nonreferred school-age children (6.8 to 14.6 years) of low-to middle-class socioeconomic background. Exploratory and confirmatory factor analyses were performed. The WISC-R factor structure model tested was Kaufman's (1975) three-factor solution that consisted of Verbal Comprehension (VC, Factor 1), Perceptual Organization (PO, Factor 2), and Freedom from Distractibility (FD, Factor 3). The results of the exploratory analyses showed Kaufman's three-factor solution for the three ethnic groups, but the order of Factor 2 and Factor 3 was reversed for the Mexican American and African American samples—thus raising questions about the comparability of the WISC-R factor structure across groups. The confirmatory analyses, which used the orthogonal nested factors approach by Gustafsson and Balke (1993), resulted in a model (for each of the ethnic groups) in which a G factor explained most of the variance (followed by the nested first-order factors—VC, PO, and FD). The results of the confirmatory analyses provide some support for David Wechsler's (1974) original intentions that the WISC-R structure is best described as having a general, or global, factor. © 1997 John Wiley & Sons, Inc.  相似文献

The purpose of this study was to examine the factor structure of the Stanford‐Binet Intelligence Scales, Fifth Edition (SB‐V), based on the Cattell‐Horn‐Carroll (CHC) theory of intelligence using a sample of 200 preschool children. The CHC framework uses three different models: one similar to Spearman's g, one similar to the Gf‐Gc model, and one representing the hierarchical three‐stratum CHC model. A confirmatory factor analysis (CFA), utilizing these three models, was conducted to determine which theoretical model best described the ability structure measured by the SB‐V. Results of the CFA revealed that, although the two‐stratum model provided the best fit statistics, a large amount of overlap existed among the broad CHC factors in this model. Therefore, these results suggested that a simple, overall ability model may be the best representation of ability for preschool children when using the SB‐V because the factors appeared to be indistinct with this age group. © 2011 Wiley Periodicals, Inc.  相似文献

Research Findings: This study examined the quality of teacher attributions for child disruptive behavior using a new measure, the Preschool Teaching Attributions measure. A sample of 153 early childhood teachers and 432 children participated. All teachers completed the behavior attributions measure, as well as measures regarding demographics, beliefs, self-efficacy, child behavior, and the quality of the teacher–child relationship with selected children. Confirmatory factor analysis demonstrated that the hypothesized 2-factor model fit significantly better than a 1-factor model, with the 2 factors being Causal and Responsibility. The resulting Causal and Responsibility subscale scores had solid internal consistency as measured by Cronbach's alpha coefficients. Significant bivariate and partial correlations with teacher practices and beliefs provided preliminary support for the measure's construct validity. Practice or Policy: Findings from this study suggest the importance of including a measure of teacher attributions in studies that explore teachers' beliefs, practices, and relationships with children.  相似文献

How the construct of vocabulary is defined remains unclear although multiple theories have been put forth. In light of the lack of empirical work investigating the dimensionality of vocabulary knowledge in Chinese, the present study investigated the factor structure of Chinese print vocabulary in a sample of 111 Taiwanese children in Grades 1 and 2. Participants completed six written measures designed to assess breadth and depth of vocabulary knowledge in receptive or expressive formats. Three hypothesized models corresponding to (1) a unidimensional model on which all six measures loaded onto, (2) a 2-factor model comprising breadth and depth dimensions, and (3) a 2-factor model consisting of receptive and expressive dimensions, were compared using confirmatory factor analyses. Results indicated that the unidimensional model was preferred over two dimensional models, indicating that it is useful to view Chinese vocabulary as a holistic construct rather than as comprising separable dimensions among young Taiwanese children.

The purposes of this study were to (a) test the hypothesized factor structure of the Student-Teacher Relationship Scale (STRS; Pianta, 2001) for 308 African American (AA) and European American (EA) children using confirmatory factor analysis (CFA) and (b) examine the measurement invariance of the factor structure across AA and EA children. CFA of the hypothesized three-factor model with correlated latent factors did not yield an optimal model fit. Parameter estimates obtained from CFA identified items with low factor loadings and R2 values, suggesting that content revision is required for those items on the STRS. Deletion of two items from the scale yielded a good model fit, suggesting that the remaining 26 items reliably and validly measure the constructs for the whole sample. Tests for configural invariance, however, revealed that the underlying constructs may differ for AA and EA groups. Subsequent exploratory factor analyses (EFAs) for AA and EA children were carried out to investigate the comparability of the measurement model of the STRS across the groups. The results of EFAs provided evidence suggesting differential factor models of the STRS across AA and EA groups. This study provides implications for construct validity research and substantive research using the STRS given that the STRS is extensively used in intervention and research in early childhood education.  相似文献

Research Findings: The main goals of this study were to examine the factor validity of the Social Competence and Behavior Evaluation (SCBE-30) scale using exploratory factor analysis and confirmatory factor analysis and to test factor invariance across gender in a sample of Italian preschool-age children (241 boys, 252 girls). The concurrent validity of the SCBE scale was examined with measures of children's popularity and rejection. Our findings replicated a 3-factor model of the SCBE scale found in other studies with 3 correlated factors of social competence, anger–aggression, and anxiety–withdrawal. Multigroup confirmatory factor analyses provided evidence of configural, metric, and partial scalar invariance of the scale across gender. Popularity was positively related to children's social competence and negatively related to anxiety–withdrawal. Rejection was positively related to children's anger–aggression and anxiety–withdrawal and negatively related to social competence. Practice or Policy: The use of the SCBE scale in the Italian educational setting may help teachers understand children's emotional and social competencies and thereby improve social adjustment in the classroom.  相似文献

The purpose of the study is to construct and validate a Chinese self-regulated learning (SRL)-based reading instruction questionnaire (CSRIQ) and to examine the relationship between Chinese reading instruction and Hong Kong students' reading development from the SRL perspective. A total of 339 Grade 10 students completed the initial CSRIQ in Study 1. Exploratory factor analysis and reliability analyses were used to assess the psychometric quality of the questionnaire, and the original CSRIQ subscales were then revised. Study 2 comprised 1,121 Grade 10 students. The factor structure of the revised CSRIQ was supported by the findings of confirmatory factor analysis. The findings of structural equation modelling indicated significant relations between SRL-based instruction and various reading-related variables. Among the four aspects of instruction, teacher support was the most positive factor facilitating Chinese students' reading development, whereas student autonomy seemed less favourable. Cultural and curricula factors affecting Chinese reading instruction in Hong Kong were discussed.  相似文献
