The metacognitive self-regulation (MSR) scale is among the most widely used measures of metacognition in educational research. However, the psychometric properties and validity of the scale have not been well established. A series of analyses on a college sample were performed to address this issue. In Study 1, a split-sample exploratory (EFA) and confirmatory factor analysis (CFA) was performed to test the one-factor specification of the MSR scale. Time and study environment (TSE), total study time, and cumulative grade performance average (cGPA) were introduced as outcome variables in a structural equation model (SEM) to examine the factors suggested by the EFA. The results of Study 1 indicated poor one-factor model fit and suggested two and three-factor models provided improved fits of the sample data. Results from the SEM indicated the novel factors from the two and three-factor models had different relationships with the outcome variables than the originally specified one-factor model. In Study 2, a modified one-factor model was introduced that consisted of nine items and was named metacognitive self-regulation revised (MSR-R). Five additional samples were included to replicate the model fit for the revised model specification. Finally, a path analysis was performed to examine the relationship of the MSR-R to variables from Study 1. The results of Study 2 revealed improved psychometric properties and reliability for the MSR-R. An indirect relationship emerged between MSR-R and cGPA through TSE. In conclusion, convincing evidence for replacing the MSR was found and implications of the revised scale for future studies was discussed.  相似文献

Although belonging in K–12 school settings has been abundantly researched and clearly defined, at the university level the research and construct definition is still in its infancy (Tovar & Simon, 2010). The present study sought to develop and validate an instrument measuring university belonging—the University Belonging Questionnaire (UBQ). In Study 1, an exploratory factor analysis was conducted with a sample of university students (N = 421), finding a reliable scale with three factors: (a) university affiliation, (b) university support and acceptance, and (c) faculty and staff relations. In Study 2, a confirmatory factor analysis on a new sample (N = 290), confirmed the final 3-factor, 24-item model. Further analyses demonstrated the convergent and incremental validity of the UBQ, as it positively correlated with measures of perceived social support, social connectedness, and general belonging. Implications and recommendations for university belonging research are discussed.  相似文献

To test the hypothesis that the basic “logic” utilized by individuals in scientific hypothesis testing is the biconditional (if and only if), and that the biconditional is a precondition for the development of formal operations, a sample of 387 students in grades eight, ten, twelve, and college were administered eight reasoning items. Five of the items involved the formal operational schemata of probability, proportions and correlations. Two of the items involved propositions and correlations. Two of the items involved propositional logic. One item involved the biconditional. Percentages of correct responses on most of the items increased with age. A principal-component analysis revealed three factors, two of which were identified as involving operational thought, one of which involved propositional logic. As predicted, the biconditional reasoning item loaded on one of the operational thought factors. A Guttman scale analysis of the items failed to reveal a unidimensional scale, yet the biconditional reasoning item ordered first supporting the hypothesis that it is a precondition for formal operational reasoning. Implications for teaching science students how to test hypotheses are discussed.  相似文献

The Educational and Career Interest scale, a self-report instrument measuring high school students’ educational and career interest in STEM, was developed and validated in two studies conducted during 2010 and 2011. Study 1 included data from 92 high school students, in which exploratory factor analysis (EFA) was conducted with an initial item pool of 20 items. EFA identified three factors: educational and career interest in science, educational and career interest in technology, and educational and career interest in mathematics. Study 2 utilized data from 658 students to revisit the three-factor model using confirmative factor analysis. The two studies provide strong evidence that the scale is both valid and reliable.  相似文献

ABSTRACT

This empirical investigation was aimed at conceptualizing, developing and validating a scale for the measurement of the quality of higher degrees by research (HDR-QUAL). For that purpose, this study specifically measured perceptions of higher degrees by research (HDR) students about the constituents of HDR quality in Pakistani tertiary education institutions. Following the 7-step process of scale development, three studies were conducted in order to develop an initial pool of scale items, establishing proposed scale validity and reliability, and assessing nomological behavior of the proposed scale. The principal component analysis with Varimax rotation method resulted in a 3-factor solution, subsequently proposing a 15-item scale. The model fit indices of measurement and the higher-order model indicated a satisfactory fit to data. Finally, the resultant three factors, i.e. financial assistance, supervisory expertise, and infrastructural support, converged into a unidimensional HDR-QUAL scale that was found positively associated with student satisfaction, thus, confirming nomological validity as well. Important policy measures and directions for future research are proposed at the end.  相似文献

The purpose of this study was to develop and validate a self-report instrument that can be used to measure learning in the cognitive, affective, and psychomotor domains. The study underwent three phases, each with its own data collection and analysis. Phase I featured the development, testing, and factor analysis of an 80-item instrument that addressed cognitive, affective, and psychomotor learning that was administered to a sample of 142 online and face-to-face learners. Based on the results, the instrument was reduced to 21 items for Phase II and tested with a new sample of 171 online and face-to-face students. The results of confirmatory factor analysis suggested a better data fit with an even smaller 9-item instrument, which was then administered to a new sample of 221 online and face-to-face students in Phase III. The results of this final phase are presented along with the resulting CAP Perceived Learning Scale, a 9-item self-report measure of perceived cognitive, affective, and psychomotor learning. Implications and usage of the CAP Perceived Learning Scale for research and practice are also discussed.  相似文献

Using a bidimensional two-parameter logistic model, the authors generated data for two groups on a 40-item test. The item parameters were the same for the two groups, but the correlation between the two traits varied between groups. The difference in the trait correlation was directly related to the number of items judged not to be invariant using traditional unidimensional IRT-based unsigned item invariance indexes; the higher trait correlation leads to higher discrimination parameter estimates when a unidimensional IRT model is fit to the multidimensional data. In the most extreme case, when rθ1 θ2= Ofor one group and r θ1 θ2= 1.0 for the other group, 33 out of 40 items were identified as not invariant. When using signed indexes, the effect was much smaller. The authors, therefore, suggest a cautious use of IRT-based item invariance indexes when data are potentially multidimensional and groups may vary in the strength of the correlations among traits.  相似文献

ABSTRACT

The Student Background survey administered along with achievement tests in studies of the International Association for the Evaluation of Educational Achievement includes scales of student motivation, competence, and attitudes toward mathematics and science. The scales consist of positively- and negatively keyed items. The current research examined the factorial structure of the 18-item motivational scales in fourth-grade mathematics in the 2011 Trends in International Mathematics and Science Study (TIMSS). Survey data from six European countries were analyzed. In comparisons of alternative models, the fit was adequate when three correlated factors were specified and negative keying was taken into account as a latent factor, or with correlated uniquenesses among negatively keyed items. Participants reading achievement scores correlated systematically to negative keying with coefficients ranging from .254 to .395 in the six samples. Unlike their higher-scoring peers, fourth-graders with lower reading achievement responded differentially to similar items depending on the direction of item keying, in such a way that their motivation scores were biased downward. Implications about the use of reverse keying in surveys for young students are discussed.  相似文献

The authors report on the development of a brief dyslexia screening measure based on revising the 65-item Hong Kong Behaviour Checklist of Specific Learning Difficulties in Reading and Writing. Teachers’ ratings of 1063 primary students aged 6–14 years on the behaviour checklist provided data for its psychometric evaluation using traditional measurement and Rasch measurement model analyses. Rasch scaling suggested that the revised 36-item checklist could be regarded as a unidimensional scale that assesses global dyslexic dysfunction, and receiver operating characteristics analysis suggested that a score of 18 could be an optimal cut-off score when it is used as a dyslexia screening measure. The validity of this revised checklist was supported by its substantial and significant correlations with external measures of literacy and cognitive skills. Implications of the findings for the use of adaptive testing to provide an effective procedure for screening are discussed.  相似文献

The purpose of my study was to develop and validate a scale to assess peer mentoring practices that aim to enhance learning. In the development process, 4 focus group interviews were conducted with 10 mentors and 12 mentees who participated in 8 weeks of peer mentoring. In addition to the literature, the findings from interviews were used to develop items. The 11-item form was administered to 126 college students. After the confirmatory factor analysis, the scale took on its final form with 10 items in 3 factors as Contribution to Mentee, Mentor Characteristics, and Peer Relationships. The results of confirmatory analysis were: GFI .92, CFI .99, NNFI .98, RMSEA .080, and Cronbach α coefficient was found to be .954.  相似文献

Sources of self-efficacy in mathematics: A validation study   总被引：1，自引：0，他引：1  
The purpose of this study was to develop and validate items with which to assess A. Bandura’s (1997) theorized sources of self-efficacy among middle school mathematics students. Results from Phase 1 (N = 1111) were used to develop and refine items for subsequent use. In Phase 2 of the study (N = 824), a 39-item, four-factor exploratory model fit best. Items were revised to strengthen psychometric properties. In Phase 3 (N = 803), a 24-item, four-factor confirmatory factor model fit best. This final model was invariant across gender and ethnicity. Subscales correlated with self-efficacy, self-concept, mastery goals, and optimism. Results suggest that the sources scale is psychometrically sound and could be adapted for use in other domains.  相似文献

Item stem formats can alter the cognitive complexity as well as the type of abilities required for solving mathematics items. Consequently, it is possible that item stem formats can affect the dimensional structure of mathematics assessments. This empirical study investigated the relationship between item stem format and the dimensionality of mathematics assessments. A sample of 671 sixth-grade students was given two forms of a mathematics assessment in which mathematical expression (ME) items and word problems (WP) were used to measure the same content. The effects of mathematical language and reading abilities in responding to ME and WP items were explored using unidimensional and multidimensional item response theory models. The results showed that WP and ME items appear to differ with regard to the underlying abilities required to answer these items. Hence, the multidimensional model fit the response data better than the unidimensional model. For the accurate assessment of mathematics achievement, students’ reading and mathematical language abilities should also be considered when implementing mathematics assessments with ME and WP items.  相似文献

The Nonverbal Literacy Assessment (NVLA) is a literacy assessment designed for students with significant intellectual disabilities. The 218‐item test was initially examined using confirmatory factor analysis. This method showed that the test worked as expected, but the items loaded onto a single factor. This article uses item response theory to investigate the NVLA using Rasch models. First, we reduced the number of items using a unidimensional model, which resulted in high levels of test reliability despite decreasing the number of questions, providing the same information about student abilities in less time. Second, the multidimensional analysis indicated that it is possible to view the NVLA as a test with four dimensions, resulting in more detailed information about student abilities. Finally, we combined these approaches to obtain both specificity and brevity, with a four‐dimensional model using 133 items from the original NVLA.  相似文献

This study established a Chinese scale for measuring high school students’ ocean literacy. This included testing its reliability, validity, and differential item functioning (DIF) with the aim of compensating for the lack of DIF tests focusing on current scales. The construct validity and reliability were verified and tested by analyzing the established scale’s items using the Rasch model, and a gender DIF test was conducted to ensure the test results’ fairness when distinct groups were compared simultaneously. The results indicated that the scale established in this study is unidimensional and possesses favorable internal consistency and construct validity. The gender DIF test results indicated that several items were difficult for either female or male students to correctly answer; however, the experts and scholars discussed these items individually and suggested retaining them. The final Chinese version of the ocean literacy scale developed here comprises 48 items that can reflect high school students’ understanding of ocean literacy—which helps students understand the topics of marine science encountered in real life.  相似文献

Nine different confirmatory factor analysis (CFA) models, including CFAs with correlated traits, uniquenesses, and methods, were employed to test the factorial structure of Rosenberg's (1965) self-esteem scale in a sample of crack-cocaine drug users. The results partially support earlier research and show that (a) there exists a single global self-esteem factor underlying responses to Rosenberg scale; (b) method effects associated with item wording exist; and (c) the method effects were associated primarily with positively, rather than negatively, worded items.  相似文献

Recycling and its applications are growing significantly due to the great potential for solving a range of environmental problems in society. Nevertheless, there are currently very few instruments that can provide valid and reliable data on students’ attitudes toward recycling. In this regard, this article focuses on the development and validation of Recycling Attitude Scale (RAS). The items in the RAS were developed initially from the responses to three open-ended items by 53 tenth and eleventh grade students and literature review on recycling attitude. This initial form was pilot tested with 356 tenth and eleventh grade students and then subjected to exploratory factor analysis. Subsequently, the revised version of the scale was administrated to 694 tenth grade students, and the results were subjected to confirmatory factor analysis and reliability analysis. The RAS consists of 21 items in three subscales, with responses recorded on a four-point Likert scale, options ranging from strongly agree to strongly disagree. Cronbach’s alpha reliability coefficient (α) of the scale was found to be .87. The results indicate that the RAS a potentially valuable tool for both instructors and researchers in Turkey for the assessment of the attitudes toward recycling held by students in secondary education.  相似文献
