With the increasing popularity of peer assessment as an assessment tool, questions may arise about its measurement quality. Among such questions, the extent peer assessment practices adhere to standards of measurement. It has been claimed that new forms of assessment, require new criteria to judge their validity and reliability, since they aim for specific goals and address different aspects of learning. But although new criteria have been formulated, little is known about how they are deployed and operate in actual peer assessment practices. This study intends to explicate the quality criteria relevant to the context of peer assessment. We conducted a survey in vocational education on peer assessment quality criteria applied in classrooms. Fifty-six teachers using peer assessment rated several quality criteria as relevant to their teaching practice. The findings suggest that peer assessment practices entail many of the quality criteria recognized in measurement and evaluation, although in an embedded way: the generic quality criteria are tuned or adapted to the peer assessment setting. The findings also show that peer assessment is very much in the hands of the teacher, who organizes and orchestrates the appraisal process in which students receive clear guidelines to appraise one another's work. Our results indicate that quality criteria hardly differ from the function peer assessment serves in classrooms, either within a summative or formative evaluation context. By gaining insight on the specific criteria of peer assessment and their precise purposes, we believe it becomes possible to help teachers improve its measurement quality. 相似文献

Does Self-directedness in Learning and Careers Predict the Employability of Low-Qualified Employees?
Isabel Raemdonck Harm Tillema Andries de Grip Martin Valcke Mien Segers 《Vocations and Learning》2012,5(2):137-151
Employability has become a key element in sustaining successful vocational careers. The role of self-directedness is considered
paramount in maintaining one’s employability. However, it also requires certain competences on part of employees to invest
in learning and career development. This study examines the influence of self-directedness in learning and career of low-qualified
employees on their employability. In a follow-up study of 284 low-qualified employees, we find that higher levels of self-directedness
in learning and career of employees corresponds with higher chance to be promoted to higher-level job positions (vertical
job mobility). However, no relationship was found between different formats of self-directedness and job retention or horizontal
job mobility of lower qualified personnel. 相似文献

This study concerns students’ ideas about the superposition of electric fields. Two paper‐and‐pencil questionnaires were given to university students to investigate possible obstacles to a correct use of this principle. The results confirm an expected difficulty about Gauss's theorem, i.e., the idea that only ‘internal’ charges create a field on a given closed surface. Another more surprising finding is that students are reluctant to admit that a field can penetrate into, or go out of, an insulator, particularly because ‘charges cannot move’. These first findings are discussed in connection with common features of students’ reasoning about mechanics and about multivariable problems. Some directions of future research are proposed. 相似文献

Data from written correspondence and conversations gathered from the authors'study on knowledge construction was used to examine the process of interpretation, or how researchers construct ‘knowledge about knowledge construction.’ The notion of ‘working in the interpretive zone’ was used to conceptualize interpretation among researchers as a collaborative act. Specifically, the authors discuss how intellectual, social, interpersonal, and dispositional aspects of their collaboration shaped their understandings about the process and outcomes of the study, the research methodology, and the theoretical insights that emerged from the study. 相似文献

This paper presents an approach to belief change in teacher education programmes. Although belief change may constitute a more relevant goal for initial teacher education than knowledge transmission and competence attainment per se, relatively few models or methods have been put forward that can help student teachers to become aware of, knowledgeable about, and actively involved in changing and (re) constructing their own teaching beliefs. The model of study teams is presented as a relevant approach to teaching in teacher education, together with some preliminary evaluations regarding its implementation. It shows that utilising study teams can have a strong impact on teacher education programmes as well as on student teachers’ thinking. 相似文献

Current theory about writing states that the quality of (meta)cognitive processing (i.e. planning, text production, revising,
et cetera) is, at least partly, determined by the temporal distribution of (meta)cognitive activities across task execution.
Put simply, the quality of task execution is determined more by when activities are applied than by how often they are applied. Planning and revising are two extreme writing styles, in which (meta)cognitive activities are temporally differently distributed across the writing
process. Planners are writers who generate plans before text production. Revisers use text production as a means to arrive
at a content plan. The present study investigates the question whether the online (meta)cognitive processing of secondary
school students during writing tasks, as measured by think aloud techniques and keystroke logging, can be predicted by their
responses to an offline questionnaire which measures to what degree students considered themselves to be planners and revisers.
It was expected that different reported writing styles would entail different temporal distributions of six (meta)cognitive
activities: reading the assignment, planning, text production, reading own text, evaluating own text and revising. This hypothesis
was partly confirmed. The results show that the online temporal distributions of reading the assignment and planning are different
for different degrees of reported writing styles. On the basis of these results, the validity of both the questionnaire and
the concept of planner and reviser styles are discussed. 相似文献

In recent publications on the use of portfolios in professional training both their goals, application and success are reported in favourable terms. The main purposes of portfolios being put forward are: documentation of performance, monitoring growth, revealing discrepancies in development and enhancing self-responsibility. The findings, however, pertain to the introductory implementation of the portfolio instrument, most notably with (student) teachers. Not much is known about the sustained use of a portfolio as an instrument to support professional development in the long term. In this study the benefits of different forms of sustained portfolio use are focused on in particular. Use is related to the portfolio's function, which can be for both professional development and certification, and to the setting and conditions of use, which may be either mandatory or voluntary. We gauge its impact on indicators like ongoing documentation, systematic reflection, dialogue with significant others and learning for professional development. The difficulties experienced users found are discussed, as well as the gains they saw in sustained use of portfolios, which led us to conclude that portfolios are mainly used for documentation but have a high potential as mirrors of competence when issued as instruments for self-evaluation and self-assessment. 相似文献

The present study examined the role of interpersonal variables (psychological safety, value diversity, interdependence, and trust) and conceptions of peer assessment in vocational education. An intervention was conducted (N = 45) with a control group (N = 17), which indicated change in psychological safety, value diversity, and trust in the peer as an assessor. Furthermore, when comparing the intervention and control group, peer assessment contributed to psychological safety and lower value diversity. Perceived learning was predicted by value diversity and conceptions. Conceptions were predicted by psychological safety, value diversity, and trust in the self and in the peer as an assessor. 相似文献
