The psychometric properties of the Infant–Toddler Environment Rating Scale-Revised Edition (ITERS-R) were examined using 153 classrooms from child-care centers where resources were tied to center performance. An exploratory factor analysis revealed that the scale measures one global aspect of quality. To decrease redundancy, subsets of items were selected randomly and by experts who rated items according to ease of administration and importance to quality. The shorter subsets demonstrated good discriminant validity, adequate to good psychometric properties, and high associations to the full ITERS-R score. They also demonstrated similar associations to staff education and staff-to-child ratio, as the full instrument. The best assessment of quality was demonstrated by the shortened subset that included items that assess both structural and process features of quality. Multilevel-analyses indicated that classrooms from the same providers score more similarly on ITERS-R than classrooms from other providers. The implications for using the ITERS-R in high-stakes contexts are discussed.  相似文献

Effects of Item Wording on Sex Bias   总被引：1，自引：0，他引：1  
This study examined the effects of gender-related item-wording changes on the performance of male and female examinees. Mathematics word problems and English language items were created in neuter, male, and female versions. Items were administered to randomly equivalent samples of about 300 high school juniors and seniors. Loglinear analysis was used to assess the impact of item gender and its interaction with examinee sex on the difficulty and discrimination of each item in each context. No items were found to have sex bias in either context. Mathematics items did not have different difficulty or discrimination in the three gender versions. Neither mathematics nor English items had different discrimination levels in the three gender-related versions. Some English items, however, were found to have different difficulty levels in the three gender-related versions. These difficulty differences were not systematic." none of the three gender versions appeared consistently more or less difficult than the others.  相似文献

The Constructivist Learning Environment Survey is an instrument used for assessing students’ and teachers’ perceptions of their learning environments. The Teacher Constructivist Learning Environment Survey (TCLES) was created to better enable teachers and researchers to determine teachers’ perception of their use of constructivist approaches in their classrooms. This article reports the development and validation of a modified Turkish version of the TCLES with 449 teachers chosen randomly from primary schools in Turkey. The validity of the TCLES was investigated by means of explanatory and the confirmatory factor analyses, whereas the Cronbach alpha coefficient was used to assess the internal consistency of the scales. The factor analyses were carried out to check the factor structure of the Turkish adaptation of TCLES. The factor analysis revealed that the Turkish adaptation of the original survey consisted of 30 items with the same six-scale structure as the original survey.  相似文献

The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ2 (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.

The study investigated the psychometric properties of the Eysenck Personality Questionnaire – Revised (EPQ‐R) Short Scale administered to two groups of Brunei trainee teachers of both genders taking psychology courses in English (117 students) and Malay (106 students). The extraversion scale had the most problematic items. Both administrations produced means and standard deviations comparable to the norms in the technical manual. All the scales, except P (psychoticism), had satisfactory levels of alpha reliability and validity (discriminant and construct) on both versions. In addition factor analysis correctly assigned some of the items to their respective scales on both versions. No statistically significant gender difference in performance on both scales was obtained. Findings suggest that the instrument was suitable for use with Brunei student teachers with tertiary‐level education when technical terms were clarified and reasonable administration time was given.  相似文献

The authors created a psychometrically sound instrument that could be used to examine K-12 teachers’ perceptions of arts integration. Ten content experts reviewed the initial survey items for construct-fit and readability. Scores from 354 K-12 teachers were examined for the survey’s initial factor structure through exploratory factor analysis (EFA). Then, scores from 1,072 K-12 teachers were analyzed to complete a confirmatory factor analysis (CFA) of the Putting the Arts and the Classroom Together (PACT) data. EFA results indicated a three-factor structure (i.e., value, willingness, and barriers), and CFA results produced model indices showing good fit of the three-factor model. For purposes of examining teachers’ practices in integrating the arts, establishing teacher receptiveness to arts integrated curriculum is important in designing and implementing any professional development program. This survey could be used to establish baseline participant perceptions for staging targeted professional development to support educators in creating appropriate arts integrated curricula.  相似文献

Research Findings: The Early Childhood Environment Rating Scale–Revised (ECERS-R) is widely used to evaluate the quality of early childhood education and its association with child development. However, the psychometric properties of the ECERS-R are not well established. Consequently, in this study we tested 3 different factor solutions of the ECERS-R using models sourced from the existing literature (featuring 1-, 2-, and 3-correlated-factor solutions) and applying confirmatory factor analysis to data from the epidemiological sample of the Embu Pre-school Mental Health Study (n = 1,292 children). Alternative measures of child education quality (such as teacher-to-child ratio) were also analyzed. The confirmatory factor analysis returned good fit indices for both the unidimensional and 3-correlated-factor solution models. Practice or Policy: This study showcases different applications of the ECERS-R, both the full and shortened versions. These findings are particularly important for improving ECERS-R guidelines for researchers, professionals, and policymakers.  相似文献

ABSTRACT

A new psychometrically acceptable measure of the desire to live a very long life was devised using two samples. In Study 1, initial exploratory analyses of the Personal Longevity Scale (PLS) scale revealed a two-factor structure. The Hope factor represents the hopefulness participants have with regards to their expectations about personal longevity. The second factor, Dread, represents the fear and uneasiness associated with self-perceptions of living a very long life. In Study 2, the bidimensional nature of the PLS measure was confirmed, and the scale was further refined to include a final of seven items. Four items represent Hope (α = .85), and three items represent Dread (α = .78). Theoretical rationales for the two-factor structure of personal longevity are discussed. In Study 3, the PLS was compared to three similar measures of attitudes about aging. The results indicate that the PLS has moderate levels of convergent and discriminant validity. Potential uses for the new scale are discussed.  相似文献

This study examined the effects of type of instructional control and program mode on the achievement, option use, time in the program, and attitudes of higher-ability and lower-ability university students. Ability level was determined using participants' Scholastic Aptitude Test (SAT) and American College Testing Assessment (ACT) scores. Participants were randomly assigned to four versions of a computer-delivered instructional program within higher-ability and lower-ability groups. The four versions of the instructional program were created by crossing the two control conditions (learner control, program control) with the two program modes (full, lean). Participants in the full program scored significantly higher on the posttest than those in the lean program, and higher-ability students scored significantly higher than lower-ability students. Learner-control participants chose to view 68% of the optional screens in the full program but only 35% in the lean one, and participants also spent significantly more time in the full version. Participants had more favorable attitudes toward learner control than program control.  相似文献

The aims of this study were to administer an assessment measure that would identify prosocial children, bullies and their victims, and to examine the underlying structure of children's perceptions of peer social behaviour in these three groups. Three versions (peer nomination, self and teacher rating) of a newly developed child social behaviour questionnaire (CSBQ) were completed by children (aged 9/10 years, n=321) and their teachers in 14 Scottish primary schools. The CSBQ is distinguished from other extant measures by its joint focus on both prosocial and antisocial child behaviours, and by its use of concrete and empirically derived items. In conjunction with sociometric data, which was also elicited from the children, the CSBQ yielded scores on 12 behavioural dimensions. Based upon the peer nomination data, a set of rigorous criteria, capable of reliably identifying children in the three groups, was developed to take account of varying peer nomination practices within and between schools. Factor analysis of the 12 measures yielded four factors (two antisocial factors, a prosocial factor and a victim factor) which accounted for 71% of the variance, and which offer further insight into the organisation of children's perceptions of social behaviour. Gender differences in peer nomination patterns and comparisons between the different informant groups are discussed in relation to previous work.  相似文献

In this study, we examine the degree of construct comparability and possible sources of incomparability of the English and French versions of the Programme for International Student Assessment (PISA) 2003 problem-solving measure administered in Canada. Several approaches were used to examine construct comparability at the test- (examination of test data structure, reliability comparisons and test characteristic curves) and item-levels (differential item functioning, item parameter correlations, and linguistic comparisons). Results from the test-level analyses indicate that the two language versions of PISA are highly similar as shown by similarity of internal consistency coefficients, test data structure (same number of factors and item factor loadings) and test characteristic curves for the two language versions of the tests. However, results of item-level analyses reveal several differences between the two language versions as shown by large proportions of items displaying differential item functioning, differences in item parameter correlations (discrimination parameters) and number of items found to contain linguistic differences.  相似文献

The Course Experience Questionnaire (CEQ) is a 36-item instrument that is intended to measure six different aspects of students’ perceptions of the academic quality of their programmes. It has been widely used in Western countries, and it has also been used in non-Western countries, including China, Hong Kong, Japan and Pakistan. Nevertheless, in the latter countries, it has sometimes not been possible to identify the full range of constructs that were supposed to be measured by the original CEQ. We translated the CEQ into Bengali and administered this to 552 science students at 15 higher secondary schools in West Bengal, India. A confirmatory factor analysis found that their responses provided a poor fit to the original six-factor model of the CEQ. An exploratory factor analysis identified just four constructs, which reflected good teaching, generic skills, student support and appropriate workload. The items with salient loadings on the four factors were used to construct four scales. The students’ scores on three of the four scales showed satisfactory levels of internal consistency. A factor analysis of their scores on all four scales yielded one overarching factor that could be interpreted as a measure of perceived academic quality. A reduced version of the CEQ consisting of the 30 items that constitute these four scales can be recommended as a measure of students’ perceptions of the academic quality of programmes in West Bengal.  相似文献

This study validated the factor structure of a popular assessment of learner's cognitive test anxiety. Following recent findings in a study with Argentinean students' use of the Spanish version of the Cognitive Test Anxiety Scale (CTAS), this study tested the factor structure using data from 742 students who completed the original English version in the United States. Comparison of three confirmatory factor analyses confirmed the prior finding that reverse-coded items included in the original CTAS produced a second factor that did not add to the model fit for the CTAS. In addition, the results identified that a reduced length (17-item) version of the CTAS that removed all reverse-coded items was preferable to the two-factor solution for the full scale. Implications for assessment of test anxiety as well as the use of reverse-coded items in self-report survey research are discussed.  相似文献

This study compared the convergent and discriminant validity of two confidence marking techniques with that of conventional choice testing. Achievement in vocabulary, social studies, and science (traits) was measured by a 60-item test containing true-false and 5-alternative items (methods). The test was administered to three randomly assigned groups (one for each response system), totaling 535 Ss. The results indicated very slight differences in convergent and discriminant validity that favored conventional choice testing over confidence marking techniques.  相似文献

The purpose of this study was to develop a valid and reliable scale for assessing high school students’ self-directed learning skills. Based on a literature review and data obtained from similar instruments, all skills related to self-directed learning were identified. Next, an item pool was prepared and administered to 255 students from various high schools. To test the suitability of the gathered data, exploratory factor analysis was performed. The results revealed that there were correlations between the items, factor analysis could be conducted and nine factors were obtained. A confirmatory factor analysis (CFA) was performed concerning the quality of the factor structure. The results of the CFA confirmed the nine-factor solution. The final version of the scale has a nine-factor structure and includes a total of 40 items. This instrument uses a five-point Likert-type scale and was termed the Self-Directed Learning Skills Scale (SDLSS).  相似文献

Abstract

Reports of all published factor analyses of student ratings of college faculty were reviewed to determine what common factors had emerged and to identify items likely to be useful in discrimination between teachers. A 39-item form was administered to students of 18 instructors both at the beginning and end of a semester course. Twenty-four items had been included in the form used earlier by Isaacson et al. (5). The current data and those collected by Isaacson et al. were analyzed by multiple discriminant analysis and the results were compared to those obtained by factor analysis. While results of the analyses were generally similar, the differences between the results of multiple discriminant analysis and factor analysis point to differences between student stereotypes of teacher behavior and differences in actual behavior between teachers. For uses in which the primary concern is to compare one teacher with another, the dimensions derived by multiple discriminant analyses seem likely to be more useful.  相似文献

This work examines the hypothesis that the arrangement of items according to increasing difficulty is the real source of what is considered the item-position effect. A confusion of the 2 effects is possible because in achievement measures the items are arranged according to their difficulty. Two item subsets of Raven’s Advanced Progressive Matrices (APM), one following the original item order, and the other one including randomly ordered items, were applied to a sample of 266 students. Confirmatory factor analysis models including representations of both the item-position effect and a possible effect due to increasing item difficulty were compared. The results provided evidence for both effects. Furthermore, they indicated a substantial relation between the item-position effects of the 2 APM subsets, whereas no relation was found for item difficulty. This indicates that the item-position effect stands on its own and is not due to increasing item difficulty.  相似文献

Few research-based measures of the family literacy environment are commercially available, especially in Spanish. One exception is the Familia Inventory (Taylor, 1995). The present study investigated the 10 subscales of this instrument and the factor structure they imply, using data from a low-socioeconomic (SES), largely Hispanic population. Confirmatory factor analysis (CFA) was used to test the structure of the instrument as well as whether it is invariant across English and Spanish language versions. The scale was administered to 232 parents of preschoolers. Results of the CFA revealed that the a priori dimensions of the Familia Inventory were not supported for this sample. Follow-up analyses suggested poor fit both within and between subscales. The scale fit poorly within both English and Spanish, precluding testing of invariance across language. Supplemental analyses using exploratory factor analysis (EFA) on a subset of the items that had adequate variance suggested that a four-factor solution accounting for 53% of the variance best represented the English data and that a two-factor solution accounting for 43% of the variance best represented the Spanish data. Implications are discussed.  相似文献
