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

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

ABSTRACT

The study presented in the paper has the following goals. The first is to review and compare teacher competence frameworks developed in Eastern (Chinese) and Western (German) contexts, exemplified for the domain of mathematics. Major similarities of the two contexts could be reconstructed in the conceptualization of teacher competence as a multidimensional construct comprising knowledge, teaching-related skills and beliefs. Distinct differences could be identified as well, with the Chinese frameworks including a wider range of teacher-competence facets and emphasizing more teaching-related competencies than the Western (German) frameworks. The second purpose is to adapt and validate a German framework of the measurement of mathematics teacher competence in a Chinese context. This adaptation and validation uses exemplarily mathematics teacher, in detail follow-up-studies of the international Teacher Education and Development Study: Learning to Teach Mathematics (TEDS-M). With the integration of a qualitative approach (e.g. elemental validity) and a quantitative approach (e.g. construct validity) to validate the framework, the results of both approaches suggest a satisfactory validity for the adaptation. Overall, the results point out that the examined teacher competence framework and its instruments can be used for comparative analyses in Germany and China.  相似文献

This study informs the design and development of pedagogical agents that can flexibly support self-regulation by calibrating guidance to specific phases and facets of self-regulated learning (SRL) as individuals encounter challenges and develop more sophisticated understandings of the task and content. From a socio-cultural perspective of self-regulation, we examine the transition of self-regulatory control from teacher to graduate student during naturalistic instructional conferences. Three goals included (a) examining teacher–student dialogue about a complex task to see if fading actually occurs, (b) examining whether support and fading of support are calibrated to specific phases of the self-regulatory process at a given point in time, and (c) examining techniques used for scaffolding and fading scaffolding directed toward specific phases and facets (behavioral, cognitive, metacognitive and motivational) of the self-regulatory cycle. Findings support a socio-cultural perspective of SRL demonstrating a transition from teacher to student regulation across phases and facets of SRL. The paper concludes with an examination of how our findings can inform the design of computer-based scaffolds that can support SRL.  相似文献

Because learning and instruction are increasingly competence-based, the call for assessment methods to adequately determine competence is growing. Using just one single assessment method is not sufficient to determine competence acquisition. This article argues for Competence Assessment Programmes (CAPs), consisting of a combination of different assessment methods, including both traditional and new forms of assessment. To develop and evaluate CAPs, criteria to determine their quality are needed. Just as CAPs are combinations of traditional and new forms of assessment, criteria used to evaluate CAP quality should be derived from both psychometrics and edumetrics. A framework of 10 quality criteria for CAPs is presented, which is then compared to Messick's framework of construct validity. Results show that the 10-criterion framework partly overlaps with Messick's, but adds some important new criteria, which get a more prominent place in quality control issues in competence-based education.  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 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

The use of electronic portfolios is increasingly becoming popular in teacher education programs. The electronic portfolio allows learners to express their work and take ownership over their own ability to plan and assess and reflect upon their learning during a specific period of time. While many teacher education programs have adopted electronic portfolios in order to meet accreditation requirements, others use electronic portfolios to develop and improve on students’ technology skills—train students on how to better use technology in instruction and student assessment. Irrespective of the reasons for adoption, there is the need to assess students’ perceptions of electronic portfolios, and especially to explore the benefits and challenges students face in using electronic portfolios in their course work. Using a qualitative research design, the current study explored teacher candidates’ attitudes toward electronic portfolios and the differences that electronic portfolios bring to their profession. Such a study is necessary to help administrators identify students’ needs to ensure that they are gaining the maximum benefits from the use of electronic portfolios in their programs of study.  相似文献

This study chronicles a 2-year school wide portfolio initiative in a British elementary school, teacher resistance to the initiative, and factors that contributed to acceptance of the portfolio initiative. Critical components to teacher engagement in this context included teacher ownership of the process and product, a child-centred focus to the portfolio, and opportunity to include belief statements and entries of felt importance. The reflective teaching portfolio is discussed as a cultural tool of mediation and a vehicle for providing programmatic reflection wherein teacher integrity can be demonstrated through alignment of beliefs and teaching practice over time.  相似文献

Teaching portfolios have been used in the preservice teacher education program at Monash University to help student teachers to reflect on their learning about learning and teaching and to help them to convey this to others. The portfolio is an open-ended and un-graded task designed to explore teaching from many different vantage points. It is organised as a dynamic assessment task, not simply a static end product. This is done by considering teaching portfolios as comprising two important aspects, one is the process the other is the product. The process involves learning from the variety of experiences offered in the preservice education program and encouraging student teachers to reflect on these. The product is the development of the individual portfolio items that are used to demonstrate this learning to others. The portfolio comprises a number of individual items which act as a prompt to “tap” the creator's understanding of what it means to be a (science) teacher. This paper reports on the effectiveness and value of portfolios from the student-teachers' perspective by exploring how their understanding of the task evolved as they completed their preservice teacher education program.  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

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

This article explores the role of a teaching portfolio in supporting the transition from teacher to teacher educator. It uses aspects of self-study to catalogue the challenges and successes during this transition. Despite well-documented acknowledgement of the differing demands of teaching when compared to teaching how to teach, little is written about potential supports during transition to teacher education. This article cites benefits associated with developing a teaching portfolio during this period of transition. The process of reflecting on a teaching philosophy, interrogating pedagogy and developing a personal and professional development plan facilitate the formation of an adapted teacher identity. In addition, the scholarly, evidence-based process of portfolio writing acts as a bridge into the research and writing world of an academic. The portfolio writing process this researcher engaged in was based on iterative feedback from more experienced colleagues internal to the institution and from external panels. This led to a supportive and collaborative induction to the role of teacher educator from a number of perspectives. The researching of my self enabled deep reflection on my teaching philosophy, supported early academic writing and facilitated relationships with staff who acted as critical friends and mentors. This promoted the implementation of an effective teacher education pedagogy through structured, reflective, and evidence-led modifications to practice. This article creates awareness of the broader role of a teaching portfolio for teachers and teacher educators, in creating rich learning experiences for the pre-service teachers we teach.  相似文献

ABSTRACT

Building on the papers in this special issue, this article uses modern conceptions of validity theory to provide a framework for considering the evaluation of teaching quality. The 3 facets of teaching quality focused on are domain conceptualization, evidence and inferences, and their evaluation. Domain definitions vary in their specificity with tradeoffs in their range of applicability and specificity of inference. Evidence collection can range from highly standardized assessments to observations that must attend to evidence from a myriad of classroom interactions. For all assessments, however, even the most standardized, different interpretations of assessment tasks can threaten the validity of score interpretations. The papers consider a range of processes that are designed to generate, support, and interrogate the validity of inferences based on assessment scores. A fundamental question underlying this type of measurement is whether differences in the quality of teaching that students experience can be causally attributed to the teacher.  相似文献

This study aimed to design and validate the Teacher Identity Measurement Scale (TIMS) for assessing primary student teachers’ professional identity. Based on identity theory and a systematic review into quantitative instruments of teacher identity, teacher identity was decomposed in four first-order constructs: motivation, self-image, self-efficacy, and task perception. This resulted in a measurement scale consisting of 46 items. The factorial design was examined by administering the TIMS to first- and second-year primary student teachers. In phase 1, involving 17 students, qualitative scale development methods were used to assess the construct validity. In phase 2, its second-order factor structure was tested and confirmed among a sample of 211 students. In phase 3, this structure was cross-validated among a new sample of 419 students. The instrument may contribute to understanding primary student teacher’s professional development and can be used as a tool to support the process of developing a professional teacher identity.  相似文献

One goal of the teacher's professional portfolio is to describe the full range of abilities and document effective teaching over an extended period of time. In this article we discuss the procedure that teachers can use in developing their own portfolio assessment to help generate data for making decisions about teaching performance. The development of a teacher portfolio requires planning, time, organization and cooperation from students, colleagues, parents and supervisors. The format of the portfolio may vary from individual to individual and be based upon personal preference. Organizations and contents of the teacher portfolio are suggested. Questions and associated lists of teaching artifacts are discussed based on the authors' experiences as early childhood classroom teachers and university professors. The answers to these questions will guide the selection of activity-generated products to best represent the essence of the teacher performance.  相似文献

In the field of initial teacher training, portfolios are widely used to assess pre-service teachers' performance as well as the outcomes of university-based teacher preparation programmes. However, little is known about the explicit design of portfolio assessment mechanisms in teacher preparation programmes. Issues related to the design and validation of portfolios for pre-service teacher assessment are a critical area of inquiry for the field of initial teacher training. In this study, perspectives were elicited from school trainee teachers and faculty from a secondary teacher preparation programme to examine the relationships identified among core competencies of a portfolio assessment framework and pre-service candidate learning outcomes. Comparative findings are presented about the relationships identified by the trainee teachers and faculty across the secondary education programme's portfolio core competencies and trainee learning outcomes. A discussion of the findings is presented with implications and future directions highlighted.  相似文献

The instructional design process in a distance education context has been well documented within the distance education literature, although most of this literature is written from the perspective of the distance education specialist. There have been few explorations of the experiences of the academic teacher in the writing process and the relationship between an instructional designer and the writer/teacher has seldom been explored from the point of view of the writer/teacher. This paper documents a collaborative process of preparing course materials for a distance education subject on curriculum. The process is described through the eyes of both the instructional designer and the writer/teacher, so capturing the procedural aspects of the event as well as the interpersonal aspects. Many facets of the process which are normally hidden from view are included in the paper as are some of the less obvious outcomes of the collaboration. The literature which calls for a consultative relationship between instructional designer and teacher is used to analyse the observations made.  相似文献

This paper explored how the use of weblogs within the portfolio framework affected portfolio production and development for student teachers, and how the weblog-based electronic portfolio (WBEP) shaped student teachers’ reflective practice during the student teaching practicum. The individuals participating in this study consisted of 31 elementary school student teachers from a national university’s teacher education program in Taiwan. Qualitative data analysis revealed that about half the participants’ WBEP maturation level were at Level 2, the Curriculum Vitae WBEP. The two most prominent features of the WBEP platform on participants’ reflective practice were personal editorship and dialogues with others. Additionally, blog publicity promoted mandated dossier-like portfolios with which to evaluate performance with respect to external evaluation requirements. Thus, the reflective themes of most WBEP contents were rather uniform in the study.  相似文献

Portfolio appraisal: In search of criteria   总被引：2，自引：0，他引：2  
Two inherently contradictory forces are pushing for reform in portfolio assessment. On the one hand there is a felt need for creating more rigid standards that operate to promote uniformity of ratings in appraisal practice to certify achievement. However, on the other hand, critical questions are being raised about separating acclaimed portfolio goals aimed both at appraising achievement while also improving quality of student learning and development. The position of portfolio assessment, which is widely used nowadays in teaching and teacher education, comes into debate. In our study, we look for actual practices in portfolio appraisal in search of criteria used for rating the quality of portfolio materials. It is our interest to find out how appraisal criteria are selected and used to evaluate achievement or to improve the quality of development and learning. In the context of teacher education, we have examined both the espoused criteria of both assessors and collectors of portfolios as well as the actual appraisal practices by looking at the judgmental orientations and supervision styles used by portfolio assessors. In addition, we offered an authentic portfolio document to be rated by different assessors to gauge and compare their quality of rating and criteria use. The actual processes we detected point to a most common practice of employing judgmental, usually normative evaluations based on assessor dependent, more or less pre-decided criteria which permit a “checkbox” approach to appraisal.  相似文献
