Quality control policies towards Dutch vocational schools have changed dramatically because the government questioned examination quality. Schools must now demonstrate assessment quality to a new Examination Quality Center. Since teachers often design assessments, they must be involved in quality issues. This study therefore explores teachers’ opinions on assessment quality evaluation criteria. Pre-vocational and vocational teachers (N=211) responded to a questionnaire. Contrary to expectations, results show that teachers deem classical and competency-based quality criteria equally important. Vocational teachers gave higher importance scores than pre-vocational teachers, possibly due to the pressure they experience to improve the quality of their assessments. 相似文献

Stage theory represents a concise explanation for change in teacher professional development with gained experience in the classroom. This study examines the self-task-impact stage chronology proposed by concerns-based theory within the framework of longitudinal research on beginning teaching. The study investigated developmental change in a panel (N=79) of beginning teachers across two years utilizing the Teacher Concerns Checklist, a concerns inventory, at six application points. Analysis of variance with Scheffé post hoc tests was utilized to rank categories of concerns and to test whether teacher and school contextual variables would affect these rankings. The results confirm findings of similar longitudinal studies, indicating teachers’ concerns for impact consistently rank highest across time. Additionally, the ranking of concerns categories was not affected by the contextual variables. Two aspects of impact, one academic in orientation and the second consisting of personal and individual concerns for students, emerged as distinct dimensions across time. The author proposes a reconsideration of concerns-based theory for its limited ability to comprehensively explain the complex nature of teacher development. Rather than chronological, concerns are recurring and indicate the need to scaffold linkages between student learning, learning theory, and instructional practices early in teaching careers in lieu of singularly focused managerial aspects of teaching. 相似文献

is a popular item fit index that is available in commercial software packages such as flexMIRT. However, no research has systematically examined the performance of for detecting item misfit within the context of the multidimensional graded response model (MGRM). The primary goal of this study was to evaluate the performance of under two practical misfit scenarios: first, all items are misfitting due to model misspecification, and second, a small subset of items violate the underlying assumptions of the MGRM. Simulation studies showed that caution should be exercised when reporting item fit results of polytomous items using within the context of the MGRM, because of its inflated false positive rates (FPRs), especially with a small sample size and a long test. performed well when detecting overall model misfit as well as item misfit for a small subset of items when the ordinality assumption was violated. However, under a number of conditions of model misspecification or items violating the homogeneous discrimination assumption, even though true positive rates (TPRs) of were high when a small sample size was coupled with a long test, the inflated FPRs were generally directly related to increasing TPRs. There was also a suggestion that performance of was affected by the magnitude of misfit within an item. There was no evidence that FPRs for fitting items were exacerbated by the presence of a small percentage of misfitting items among them. 相似文献

Background: There are some theoretical evidences that explain the relationships between core beliefs (i.e., epistemological beliefs) and peripheral beliefs (self-efficacy in learning) in the literature. The close relationships of such type of beliefs with attitudes are also discussed by some researchers. Constructing a model that investigates these relationships by considering theoretical and empirical evidences can empower researchers to discuss these relationships more comprehensively.Purpose: The purpose of this study is to explore the relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.Sample: A total of 632 high school students participated in this study; however, 269 female and 229 male (a total of 498) high school students’ data were used.Design and methods: Three distinct instruments that measure scientific epistemological beliefs, self-efficacy in learning physics and attitudes toward physics were combined into a unique questionnaire form and it was distributed to high school students. To explore the relationships among these variables, structural equation modeling was used.Results: The results showed that scientific epistemological belief dimensions uncovered by the nature of knowing (source and justification) significantly and positively related to both self-efficacy in learning physics and attitudes toward other important physics dimensions. Additionally, self-efficacy in learning physics significantly and positively predicted attitudes toward multiple physics dimensions (importance, comprehension and requirement). However, epistemological belief dimensions related to the nature of knowledge (certainty and development) did not have significant impact on self-efficacy in learning physics or attitudes toward physics.Conclusions: This study concludes that there are positive and significant relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics. 相似文献

Abstract The authors used data from the Longitudinal Study of American Youth to investigate variables related to change in students' attitude toward and beliefs about mathematics in middle school and high school. Using hierarchical linear modeling techniques, the authors modeled variation in students' rate of change with variables associated with student characteristics, instructional experiences, and environment. They also identified variables that differentially affect change at different levels of secondary school (i.e., middle school vs. high school) and for different affective dimensions (i.e., attitude toward mathematics, beliefs about the social importance of mathematics, and beliefs about the nature of mathematics). Results showed a substantial negative change in students' attitudes toward and beliefs about the social importance of mathematics throughout secondary school. However, students' notions of the nature of mathematics did not change throughout secondary school. The authors identified variables related to change and found that they differed according to the level of secondary school and affective dimensions. 相似文献

We explored Grade 6 students’ (n = 202) self-efficacy, epistemic beliefs, and science interest over a 10-day virtual ecology curriculum. Pre- and post-surveys were administered, and analyses revealed that (1) students became more self-efficacious about inquiring scientifically after participating in the activity; (2) students on average evinced a shift toward more constructivist views about the role of authority in justifying scientific claims; (3) students who identified more strongly with being a science person evinced greater gains in self-efficacy, developed a less constructivist view about the role of authority in justifying claims, and became more interested in science overall; and (4) students who held an incremental theory of ability evinced greater gains in self-efficacy. We discuss the implications of these findings for science educators and instructional designers in the design and use of immersive virtual worlds for middle school science students. 相似文献

Research on teachers’ professional identity integrates many constructs that are treated independently in most cases. This study described the associations between components of teacher professional identity and their association with teachers’ general pedagogical beliefs. Secondary teachers (n = 236) completed a survey about several components of their identity (self-efficacy beliefs, motivation to become a teacher, affective commitment and perceived type of expertise) and general pedagogical beliefs (constructivist and direct transmission). Multidimensional scaling revealed that the components could be mapped on two dimensions: form of motivation and degree of subject specificity. The resulting map revealed four meaningful groups of components. Furthermore, whereas direct transmission general pedagogical beliefs were found to be strongly tied to an identity grounded in the subject taught, constructivist beliefs were independent of identity components. This study provides new insight into the structure of teacher professional identity and its relevance for teaching. 相似文献

This study concerns the relation between teachers’ beliefs towards teaching behaviour and their actual teaching behaviour in teacher portfolio assessment. We analysed the beliefs and behaviour of 18 teachers as described in their portfolios. In addition, each portfolio was independently assessed by two trained raters on eight content standards and the teachers’ classroom behaviour was assessed by their own students in a questionnaire (n=317). Linear multilevel analysis showed that part of the raters’ assessments of the teachers’ beliefs and their behaviour as described in their portfolios was significantly related to the students’ assessments of their teachers’ behaviour. Teachers with high raters’ assessments on the content standard about ‘choosing and arguing for teaching strategies that meet students’ knowledge, abilities and experience’ had significantly higher student assessments than teachers who were judged low on this standard. Implications of the results and suggestions for further research are discussed. 相似文献

Scholars and teacher educators alike agree that teachers’ beliefs and attitudes toward mathematics are key informants of teachers’
instructional approaches. Therefore, it has become clear that, in addition to enriching preservice teachers’ (PSTs) knowledge,
teacher education programs should also create opportunities for prospective teachers to develop productive beliefs and attitudes
toward teaching and learning mathematics. This study explored the effectiveness of a mathematics preparatory program based
on the history of mathematics that aimed at enhancing PSTs’ epistemological and efficacy beliefs and their attitudes toward
mathematics. Using data from a questionnaire administered four times, the study traced the development of 94 PSTs’ beliefs
and attitudes over a period of 2 years. The analysis of these data showed changes in certain dimensions of the PSTs’ beliefs
and attitudes; however, other dimensions were found to change in the opposite direction to that expected. Differences were
also found in the development of the PSTs’ beliefs and attitudes according to their mathematical background. The data yielded
from semi-structured follow-up interviews conducted with a convenience sample of PSTs largely corroborated the quantitative
data and helped explain some of these changes. We discuss the effectiveness of the program considered herein and draw implications
for the design of teacher education programs grounded in the history of mathematics.
