The purpose of this study was to develop a scale for measuring prospective science teachers’ awareness of waste recycling. The study was conducted with the participation of 382 prospective teachers attending a university located in northern Turkey. The five-point Likert type scale that was developed contained 82 items relating to prospective science teachers’ awareness of waste recycling. The factor analysis conducted showed that five items had factor loadings below 0.30, and five were cross loading items. Factor analysis was repeated after removing these items. A further 24 items were removed from the list at the end of the factor analysis, and the remaining 48 items were grouped under ten dimensions. The reliability coefficient for the factors extracted varied between 0.717 and 0.805, and the internal reliability coefficient for the whole scale was 0.905.  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

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 Pervasive Developmental Disorders Rating Scale (PDDRS; Eaves, 2003) is a rating scale that is used in the screening process for pervasive developmental disorders (PDD). The PDDRS contains three scales: Arousal, Affect, and Cognition. In this study, the construct validity of the PDDRS was examined with teacher ratings from a sample of 168 children with autistic disorder through exploratory and confirmatory factor analysis. In the exploratory factor analysis, a three‐factor structure was examined. Confirmatory factor analysis was employed to evaluate the model‐fit of the data for the hypothesized second‐order factor structure. The results supported the averred factor structure of the PDDRS with teacher ratings for students with autistic disorder. Limitations of the data and areas for future research are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 207–216, 2005.  相似文献

Not much is known about mathematics teachers’ values, and no assessment tool is available for measuring these to get more insight into their perspectives. The goals of this study are to construct the Mathematics Teachers’ Values Questionnaire (MTVQ) and to determine mathematics teachers’ values about teaching mathematics using the MTVQ. In order to do this, data have been gathered for exploratory factor analysis (n = 637) and confirmatory factor analysis (n = 573) while developing the instrument, and a proportional stratified random sample has been formed consisting of 2226 Turkish middle and high school mathematics teachers working at schools that provide more religious education than other middle and high schools. Five components have been extracted: relevance (C1), practice (C2), information and communications technology (ICT; C3), teaching approach (C4), and consolidating (C5). One result of the study reveals the mathematics teachers emphasize the least ICT value and the most consolidating value.  相似文献

Researchers state that teachers in different contexts reported different technological pedagogical content knowledge (TPACK). This phenomenon may partially be explained by cultural differences. Based on this consideration, the development and validation of the Chinese pre-service teachers’ technological pedagogical content knowledge (CTPCK) scale is described in this article. The sample was split into two subsamples on random basis (n1 = 229, n2 = 207) for the purpose of conducting (1) exploratory factor analysis (EFA) and (2) confirmatory factor analysis (CFA), respectively. After the EFA, the CTPCK scale excluded six items and included eight factors with 42 items. Reliability and correlations were discussed. The findings revealed that the CTPCK scale was a valid and reliable instrument for measuring the TPACK of Chinese pre-service teachers’ knowledge with or without linking educational technology.  相似文献

Many teachers in higher education use feedback from students to evaluate their teaching, but only some use these evaluations to improve their teaching. One important factor that makes the difference is the teacher’s approach to their evaluations. In this article, we identify some useful approaches for improving teaching. We conducted focus groups with award-winning university teachers who use student evaluations to improve their teaching, and we identified how they approach their evaluation data. We found that these teachers take a reflective approach, aiming for constant improvement, and see their evaluation data as formative feedback, useful for improving learning outcomes for their students. We summarise this as the improvement approach, and we offer it for other teachers to emulate. We argue that if teachers take this reflective, formative, student-centred approach, they can also use student evaluations to improve their teaching, and this approach should be fostered by institutions to encourage more teachers to use student evaluations to improve their teaching.  相似文献

The present study examined the factor structure of the Teacher Involvement Questionnaire (Involve-T) by means of exploratory factor analysis and examined the association between children's socio-emotional and behavioural problems and teacher-reported parental involvement in school, using structural equation modelling. The study was conducted with a Norwegian sample of school children in Grades 1–3. Results of the factor analysis supported the use of 3 separate scales, as suggested by the scale author (Webster-Stratton, 1998); however, a number of items in each scale were reduced. Furthermore, the results showed among other findings that teachers reported more frequent contact with parents of children with conduct problems than with those of children who did not display conduct problems, and that parents of children with high levels of socio-emotional competence were more involved in their children's education than other parents. The results need to be replicated in future research in a more representative study population.  相似文献

The purpose of this study was to use the Stages of Concerns (SoC) framework established by Hall and Loucks as a way to usefully identify types of teachers. Teachers who participated in the study were attending a professional development program called Great Expectations (GE). A modified version of the SoC questionnaire was used, so an exploratory factor analysis (EFA) of the modified questionnaire was conducted and identified a five factor structure. Using these five factors, a latent profile analysis was conducted to identify teachers. Three types of teachers emerged: enthusiastic teachers, teachers who were uninterested in the GE program, and teachers who were interested in the program but still had trepidations. These three groups were then compared on their emotions prior to the beginning of the GE program and their experience with GE. The quantitative results from this study are compared to qualitative results from previous research on teachers' SoC.  相似文献

Despite the advocated importance of twenty-first century competences in education, it appears that they are not systematically integrated in national curricula, school curricula and classroom activities. Potential explanations can be found in the current ambiguity of definitions for twenty-first century competences and the absence of educational actors in curriculum development. Responding to both shortcomings, this study aims to explore how teachers’ conceptualization and enactment of twenty-first century competences constitute dimensions that can inform curricular guidelines. An exploratory factor analysis of teachers’ self-reported classroom activities that foster students’ twenty-first century competences was conducted. The data comprised responses of 2,804 primary- and secondary-school teachers to a web-survey about the perceived occurrence of specific classroom activities targeting twenty-first century competences. Results suggested six coherent dimensions of classroom activities that foster twenty-first century competences: digital literacy, innovative thinking, critical thinking and communication, (digital) citizenship, self-regulated learning, and (computer-supported) collaborative learning. Nevertheless, there were substantial interrelationships among the six dimensions. This demonstrated that teachers did not perceive twenty-first century competences to be fostered by disconnected classroom activities, but that they already have a more integrative conception of the curricular innovation. The implications of these findings for curricula, teaching practice and research are discussed.  相似文献

The aim of this study was to develop a measurement instrument which is compatible with literature, of which validity and reliability are proved with the aim of determining interaction perceived by learners in online learning environments. Accordingly, literature review was made, and outline form of the scale was formed with item pool by taking 14 expert opinions. As a result of exploratory factor analysis of data obtained from participation of 177 learners from eight different universities, it was seen that the scale consisted of 30 items and 3 dimensions. These dimensions are learner–content interaction, learner–instructor interaction and learner–learner interaction. Cronbach Alpha reliability coefficient of the whole scale was .95. Confirmatory factor analysis showed that fit indexes of the structure provided a good and acceptable fit. Based on these findings, Perceptions of Online Interaction Scale is a valid and reliable tool that may be used in measuring interaction occurring in online learning environments.  相似文献

The main purpose of this research was to examine the relationships among school principals’ transformational leadership, school academic optimism, teachers’ academic optimism and teachers’ professional commitment. This study conducted a questionnaire survey on 367 teachers from 20 high schools in Taiwan by random sampling, using principals’ transformational leadership scale, a school academic optimism scale, teachers’ academic optimism scale, and teachers’ professional commitment scale. The results of confirmatory factor analysis showed that there is good fit in the factor structure of school academic optimism and teachers’ academic optimism. The results of the Pearson product-moment correlation analysis and path analysis revealed that principals’ transformational leadership has a positive effect on school academic optimism and teachers’ academic optimism. School academic optimism has a positive effect on teachers’ academic optimism. Principals’ transformational leadership and teachers’ academic optimism have a positive effect on teachers’ professional commitment. Finally, this research offers some suggestions based on the results.  相似文献

This study investigates the development of an instrument to explore the views of student teachers in Turkey towards using Facebook as a tool for teaching and learning. A five-point Likert-type scale was developed for a sample of 687 student teachers from various fields in Adiyaman, Mustafa Kemal, and Inonu Universities. The sample included 445 participants in the first application and 242 participants in the second. A literature review, students’ comments, and relevant Facebook research results were considered in order to establish the items for the scale. A comparative analysis of previous studies and instruments yielded an original 33-item pool, and experts’ judgments were consulted to confirm the content validity of the scale. Exploratory and confirmatory factor analyses were conducted to determine the factor structure of the scale, revealing 17 items that could be grouped under three general factors. A Cronbach’s coefficient (α) was employed to determine the internal consistency coefficients for the whole scale and its subscales. Results indicate that this learning scale (FLTS) is a valid and reliable instrument to investigate the use of Facebook as a learning tool.  相似文献

As part of a three-phase study, 18 items were developed to measure aspects of a student’s willingness to seek help from and/or work with peers and teachers when studying college mathematics. In the first phase, 24 items were developed and administered to 165 undergraduate college students. During the second phase, 20 items, modified from the first instrument, were completed by a sample of 314 undergraduate college students. The sample was randomly divided in half and principal factor analysis with varimax rotation was performed on the first half. Two factors emerged and were interpreted as: Willingness to Work with Students (nine items); and Willingness to Seek Help from Teachers (nine items). Based on the results of the exploratory factor analysis, confirmatory factor analysis was performed on the second half of the sample. Coefficient α estimates were calculated to assess internal consistency. In the third phase, the final 18-item survey was given to 140 undergraduate college students and confirmatory factor analysis was again performed based on the results of the exploratory factor analysis from Phase II. Recommendations for future uses of these scales are given.  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

The primary purpose of the study was to create and psychometrically test an instrument which measured teachers’ perceptions of characteristics of professional development. The sample consisted of elementary teachers from five school districts in Washington State participating in a district improvement initiative. Results of exploratory factor analysis resulted in a five-component solution which provided evidence of construct validity. All components/subscales had moderate to strong internal consistency as measured by Cronbach’s alpha. The secondary purpose was to determine if characteristics of professional development predicted teachers’ use of new knowledge and skills, and student learning outcomes, thus contributing to the predictive validity of the instrument. There was a slight, but significant, correlation between Active Learning in Classroom and teachers’ use of new knowledge and skills, as measured by classroom observation scores. A small negative correlation emerged between Collective Participation and student learning, as measured by student scores on the state’s mathematics assessment. Potential uses of the instrument, called Characteristics of Teacher Professional Development (CTPD), are discussed.  相似文献

The job demand-control (JDC) model has dominated research into occupational stress for the last 20 years. Two concepts lie at the core of the demand-control model: job demands and job control. Control is also referred to as decision latitude and the concept has two facets: decision authority and skill discretion. The purpose of the current study was to conduct an empirically correct specification of the key concepts of the JDC model. The Scandinavian version of an instrument assessing the key concepts of the model was used and the objective of the study was to test the validity and reliability of the Finnish version of the job content questionnaire (JCQ) among teachers and nurses. Altogether 1028 teachers and 630 nurses participated. Exploratory factor and confirmatory analyses were employed to assess the factorial structure of the Finnish version of the JCQ and to evaluate which factorial model fitted the data best. Analyses indicated a factor solution with two factors: job demands and decision authority. The confirmatory factor analyses supported the results from the exploratory factor analyses. The model which fitted the data best was the model with two oblique factors with the items measuring skill discretion removed. Based on the results of exploratory and confirmatory factor analyses it seems reasonable to measure job demands and control in this sample with two factors: demand and decision authority.  相似文献
