This article concentrates on the validity and reliability of portfolio assessment as used in pre‐service teacher education. It is not possible to make general pronouncements about the validity of portfolio assessment in pre‐service teacher education as there are multiple portfolio applications. The validity depends on the purpose, namely the divers competencies which the course organisers wish to assess with it. Therefore, three categories of competencies and consequently three types of portfolios were distinguished in order to determine the validity of portfolio assessment. For the assessment of teaching and partnership competencies, it is argued that the validity is low due to the roundabout nature of the assessment. On the contrary, the validity of portfolio assessment for learning competencies can be high. The execution of a self‐regulated learning process can be accurately assessed using portfolios. The reliability of portfolio assessment is problematic, since it is incapable of fulfilling the classic psychometric requirement of reliability. Nevertheless, provided that the necessary measures are taken, the reliability of portfolio assessment can still be brought to an acceptable level. Five measures are proposed.  相似文献

This article considers the various uses of e‐portfolios in an educational context and looks at the particular characteristics of the electronic version of portfolios. It then focuses on the application of the e‐portfolio as an assessment method. A case is made for the use of the e‐portfolio as an appropriate end of course assessment process where learning objects are the basis of the course design. Evaluation data from such a course is presented. This is a post‐graduate online course run by the Institute of Educational Technology at the Open University. Conclusions are drawn from the evaluation about the appropriateness of e‐portfolios as an end of course assessment method.  相似文献

Two teacher institutions in Norway involved in a new ICT‐supported portfolio project provide data for our study. In this paper we present a model of analysis for portfolio processes based on sociocultural perspectives of learning and assessment and describe and discuss differences and similarities of the portfolio models in these institutions in relation to our model of analysis. We also highlight areas for improvement; among them the importance of building reflection, self‐assessment and feedback into portfolio assignments and processes in such a way that it becomes part of what is documented. This will strengthen the formative assessment aspect of portfolios. The summative assessment practices are strongly influenced by exam traditions in both institutions. Digital portfolios provide new learning opportunities that are not yet fully utilized. By way of conclusion we explore some critical aspects of portfolios in teacher education in light of Wenger's social theory of learning, focusing on the concepts participation, reification and identity formation.  相似文献

In an attempt to gain a fuller understanding of the basis of grading, ten assessors each assessed two portfolios drawn from the course archive which had been produced by participants on a course in teaching in higher education. Assessors gave a grade or judgement on each of a portfolio's 75 portfolio elements, reasons for each judgement they made, and recorded any alternative judgement they had considered. There were substantial differences between the judgements made during the study and those made when the portfolios were originally assessed. This article explores the differences between the original and experimental assessments, and then analyses reasons given by assessors for the judgements made. Beyond these particulars, the paper suggests some fundamental and problematic issues about the conduct and the reform of assessment, and offers a process which can be used to investigate and improve the quality, in particular the reliability, of any summative assessment.  相似文献

The richness and complexity of video portfolios endanger both the reliability and validity of the assessment of teacher competencies. In a post-graduate teacher education program, the assessment of video portfolios was evaluated for its reliability, construct validity, and consequential validity. Although video portfolio facilitated a reliable and valid assessment of teacher competencies, procedures to improve assessment quality were also revealed and are therefore discussed: more explicit grounding of assessment results in the data, peer debriefing, prolonged engagement with the assessment data, cross-checking to find confirmatory or counter examples.  相似文献

This article focuses on the use of portfolios for learning and professional development in Higher Education (HE). Recent research findings related to learning and assessment help to contextualize the study. The use of portfolios for summative assessment and development of teaching and reflective practice dominates the literature. What is lacking is research that provides insights into how a portfolio for learning can be used in HE to develop understanding into one’s own learning, assessment and professional practices. The action research findings related to portfolio use for learning purposes identified in the three case studies include: the importance of establishing the purpose of the portfolio; the impact of portfolio use on the approach to learning, to teaching and to professional development; the changes to professional practice brought about as a result of the learning; and the need to consider issues related to ethics and confidentiality.  相似文献

Portfolios are an established method of assessment, although concerns do exist around their validity for capabilities such as reflection and self‐direction. This article describes an e‐portfolio which closely aligns learning and reflection to graduate capabilities, incorporating features that address concerns about portfolios. Students are required to complete assessments linked to graduate capabilities. In Year 3, a portfolio review occurs (205–248 students per year), focusing on students' grades and feedback from assessments and a reflective essay is submitted. In the essay, students reflect on their progress, identify areas of weakness and detail plans for improvement. Progress in each capability is summatively graded against specific criteria and feedback is provided. Students progressively accumulate evidence of learning linked to the graduate capabilities. The provision of sufficient structure prevents evasion of areas of weakness. Importantly, the equal weighting given to all graduate capabilities emphasises that competence in all areas is required. The requirement for a degree of self‐direction and reflection in all assessments promotes regular review of progress. This e‐portfolio explicitly links graduate outcomes with assessment in order to drive learning. Further research is required to evaluate acceptability to students, as well as the efficacy of portfolios in developing reflective practice and self‐directed learning.  相似文献

The point of departure for this article is the ‘chameleon’ aspect of portfolios and the diversity of portfolio models and practices in higher education on the international arena today. Our aim is to investigate the contextual character of this diversity by using Norwegian higher education as an example and to show how macro‐level influences, particularly the Bologna related Quality Reform, have shaped the overall development of portfolio practices. We contextualise and discuss the sudden expansion of learning and assessment portfolios in Norway after 2002. Our data are primarily a nationwide survey of portfolio practices, supplemented by findings in a research evaluation of the reform and previously published case studies. The majority of portfolios in Norwegian higher education can be classified as ‘disciplinary‐based course work portfolios’ and they typically serve a combination of learning and assessment purposes. But within this category we found systematic differences between different educational areas where the main dividing line seems to be between professional and non‐professional education. The underlying research perspective is sociocultural and this directs our attention to contexts, cultures and traditions that shape portfolio development and practices rather than to individual differences (micro level).  相似文献

Student learning is the strongest criterion for evaluating effective teaching. This article looks at three practices which partner students, teachers, and faculty peers in understanding the quality of teaching and learning through student course portfolios and teacher course portfolios, majors portfolios and teaching portfolios, and collaborative classroom assessment. Two outcomes of using a learning paradigm are building community and representing successes in higher education through documentation of effective teaching and learning.Barbara L.

Teaching portfolios have become commonplace in the US in teacher education programs, in the process of granting an initial teaching license, in teacher recertification, and in National Board certification. This paper focuses on the use of teaching portfolios in preservice teacher education programs and analyzes the various ways in which portfolios have been conceptualized and implemented. A conceptual framework is proposed to enable researchers to describe the conditions of portfolio use. A presentation of the conditions of portfolio use will enable a greater understanding of the ways in which teaching portfolios impact teacher development and the quality of teacher assessments under different conditions of use. The paper concludes with a discussion of the key issues that have emerged in the use of teaching portfolios in preservice teacher education in the US.  相似文献

Portfolio assessment is one of the most interesting and widely discussed of the new alternative assessments. In this paper we explore the portfolio metaphor as it is applied to literacy portfolios. We suggest that portfolios provide a powerful tool for the enhancement of instruction and assessment, addressing educators' concerns about authentic assessment, documentation of academic progress, and teacher and student involvement. However, we caution that there are many important and unresolved issues that must be confronted if portfolio assessment is to succeed. Fundamental issues of validity and reliability must be addressed as well as practical issues of implementation, standard setting, sufficient resources, and teacher expertise. We argue that the ultimate success of portfolios will rest on our ability to communicate portfolio-based assessment information to others. We offer the teacher's class portfolio as a promising strategy for aggregating and reporting information, while preserving the integrity of individual student portfolios and teacher judgment. Whether the emphasis is on individual student portfolios or classroom portfolios, educators must be committed to the staff development and additional research that portfolio assessment demands.  相似文献

This paper reviews a range of challenges and tensions experienced when using portfolios for learning as well as for summative assessment in the context of continuing professional learning in academic development programmes. While portfolios are becoming increasingly prominent, the details of how they are used are under-examined; they are often simply assumed to be an appropriate tool. However, it is important that, as practitioners, we are able to justify our own assessment practices and convey our expectations to our participants, who may be unfamiliar with the demands of a reflective portfolio. In this paper we explore some of the appeal as well as the difficulties of using portfolios, many of which arise from the fact that portfolios are often simultaneously used for summative and formative purposes. We suggest how the challenges sometimes experienced with portfolio assessment can be addressed by course conveners.  相似文献

The Digital Portfolio Project at Newcastle University aimed over one year (2002/2003) to support teachers in producing, storing and accessing assessment portfolios of learner’s work using information and communications technology (ICT). This paper draws on evidence of pupil views collected as part of 14 teacher‐led case studies. The teachers all approached the task of developing digital portfolios in different ways and the variety of end products was large; however, the common result was the value placed on using the portfolio as a tool for reflection and celebration of children’s learning. As part of the data collection teachers were encouraged to gather pupil views about the digital portfolio learning process. These comments provide an interesting and surprisingly analytical perspective of the research and learning process not commonly considered in the academic community. This paper documents the pupils’ views and uses them to review the strength of the digital portfolio process and the benefits of using it in the primary classroom.  相似文献

Student portfolios are increasingly used for assessing student competences in higher education, but results about the construct validity of portfolio assessment are mixed. A prerequisite for construct validity is that the portfolio assessment is based on relevant portfolio content. Assessment criteria, are often used to enhance this condition. This study aims to identify whether assessment criteria can improve content, argumentation and communication during teacher moderation while judging student portfolios. Six teachers scored 32 student portfolios in dyads with and without assessment criteria. Their judgement processes were qualitatively analysed. Results indicated that the quality of their judgement processes was low, since teachers based their judgements mainly on their own personal opinion and less on evidence found in the portfolio. Teachers barely paid attention to quality checks and easily agreed with each other. When teachers used assessment criteria, the quality of their judgements slightly improved. They based their judgements more on relevant evidence, used less personal experiences and more often checked the quality of their judgement processes. It is concluded that the quality of teacher portfolio judgement is low, and that the use of assessment criteria can enhance its quality.  相似文献

This study aimed at investigating the role of electronic portfolios in fostering pre‐service teachers’ reflective thinking. The research was conducted with pre‐service English language teachers enrolled in a practicum course in an undergraduate teacher education programme in Turkey. The data were collected through e‐portfolios and interviews. The findings revealed that e‐portfolios gave participants a sense of ownership, fostered reflecting thinking, supported collaboration and allowed them to make connections between theory and practice. With the on‐going nature of the e‐portfolio, participants had the chance of developing and reviewing their portfolio artefacts whenever and wherever they wanted. Therefore, electronic portfolios allowed teacher candidates to reflect more on their own work and thus engage in on‐going professional development.  相似文献

This paper explores the relationship between the subject philosophy of English teachers and their assessment practices. The research is contextualised within the wider debate about the validity and reliability of course work‐based assessment in English. It examines the history of that debate and then looks at ways in which practitioners and exam boards have sought to grapple with the issue of reliability and validity within English assessment. The research contributes to the debate by suggesting, through a small‐scale indicative study, that English teachers are not influenced by their subject philosophies when assessing pupils' course work but by their understanding or ‘construct’ of grade boundaries.  相似文献

The premise that underlies the preservice‐teacher‐education programme at Monash University is the need to focus on the nature of learning (for example, Gunstone et al., 1993). One approach currently being used to enhance this process is the use of portfolios. The portfolio is an open‐ended task designed to explore teaching from many different vantage points. It is organised as a dynamic assessment task through which the student teachers work on developing their understanding of what it means to be a science teacher, and the teaching portfolio itself is a mixture of artefacts designed to help student teachers demonstrate this to others. This paper reports on the effectiveness and value of portfolios in helping preservice teachers learn about learning and teaching.  相似文献

Portfolio assessment has become a popular medium for merging classroom assessment with large-scale testing, but adoption of portfolios in the classroom for external assessment purposes may be difficult because the use of such portfolios may require changes in the curriculum, instructions, and assessments used by teachers. As a result, there are numerous potential barriers to the adoption of portfolios that can be used for large-scale assessment purposes. This study investigates how secondary teachers' perceptions of portfolio implementation barriers changed when teachers participated in a 1-year portfolio implementation effort. Survey results are analyzed with a Rasch rating scale model. Results suggest that teachers' apprehension about portfolio barriers increased slightly, but that this increase can be attributable to teachers with little portfolio experience. Furthermore, teachers' concerns about the amount of time required to develop and score portfolios increased substantially while concerns about the availability of resources and resistance from parents decreased.  相似文献

Personal theory and reflection in a professional practice portfolio   总被引：1，自引：1，他引：0  
Portfolios are widely used in the assessment of professional learning. Although claims are made that portfolios promote reflection, the nature of such reflection and the mechanisms that promote it in the portfolio process are not well understood. A four‐year action research project investigated a professional practice portfolio for high stakes assessment in a post‐graduate programme for special education resource teachers (RTs) that was preparing them for a paradigmatically different role. This paper focuses on the requirement to submit a personal theory (PT) statement in the portfolio. Although tension between the summative and formative purposes of the portfolio was evident for some RTs, a more comprehensive understanding of reflection was evident and many RTs reported that articulating their PT (often for the first time in their career) impacted positively on their ability to reflect on practice.  相似文献

It is necessary for teachers to consider alternative means of evaluating their students. One method proving to be effective for gathering and organizing student productivity, growth, and development is the portfolio approach. This article describes the Early Childhood Portfolio Assessment Preparation (ECPAP) Model that was used to facilitate the use of student portfolios in two different early childhood education programs. The goals of the model, the six steps followed and the participants' responses to this project are discussed. This article may serve early childhood directors and supervisors who are preparing teachers to implement student portfolios as a supplement or an alternative to the existing assessment and evaluation programs. Also early childhood teacher education students can benefit from the design and implementation of ECPAP.  相似文献
