Co-assessment is a type of participatory assessment in which the teacher and student jointly discuss, negotiate and assess the student’s task or performance. Although the literature on co-assessment is scarce, some authors highlight the benefits for students of participating in co-assessment in higher education, including learning, improved communication, and greater assessment literacy. This study has a double objective: on the one hand, to analyse the strengths and limitations perceived by students participating in co-assessment practices; on the other hand, to explore the strengths, weaknesses, opportunities and threats perceived by professors participating in the experience. The study was developed in 8 class groups with the participation of 470 students and 4 teachers. The qualitative analysis of the data obtained from the questionnaires and focus groups indicates that the students acknowledged several strengths, among which learning from mistakes was prominent. Students also noted some limitations, particularly the lack of adjusted scoring. Professors offered another perspective that complemented the vision of their students, noting that co-assessment presents opportunities as well as risks that may jeopardise its implementation.  相似文献

According to the Chronicle of Higher Education, “Hispanics” comprise only 4% of the full-time faculty in U.S. universities, although Latin@s comprise 16.4% of the U.S. population. Given the under-representation of Latin@ faculty, efforts to support and retain them are paramount. Recently a small body of literature has surfaced explicitly centering the practices of peer mentoring among Latin@s. Through collaborative auto-ethnography and counter-storytelling, using a framework of disidentification, muxerista mentoring, and community cultural wealth, we add to this literature by discussing our experience of engaging in non-hierarchical Latina peer mentoring at a predominantly White university. The main themes include: merging emotional needs with professional growth, forging learning and research partnerships, Browning teaching spaces and transforming institutional practices.  相似文献

Abstract

This study is part of a larger project focused on the development of argumentative competence and its effect on knowledge construction. It aims to analyse and compare the changes in the evolution of the claims and the quality of the written arguments used by university students in two learning scenarios: a first scenario where students participated in a debate with the aim of convincing; and a second scenario where the debate was aimed at achieving an agreement by consensus. The participants were 77 first-year university students in Education and Speech Therapy. A quasi-experimental design was adopted with repeated measures, in which students from the two groups wrote two argumentative texts (initial and final) for each type of debate. The results indicate that the initial claims evolved towards more moderate positions at the end of the process; and the quality of the arguments that students wrote in their texts varied significantly depending on the type of demand and the time of writing (initial or final).  相似文献

Recent research in chemistry education has shown an increasing interest in the facilitation of conceptual change in student understanding of chemical concepts. Most of the studies have tried to show the difference in student performance on algorithmic and conceptual problems. The objective of this study is to go beyond and design a teaching strategy based on two teaching experiments that could facilitate students' conceptual understanding of electrochemistry. The study is based on two sections (control, n = 29; experimental, n = 28) of 10th grade high school students at a public school in Venezuela. Experimental group participated in two teaching experiments designed to generate situations/experiences in which students are forced to grapple with alternative responses leading to cognitive conflicts/contradictions. Results obtained show that learning electrochemistry involves both algorithmic and conceptual problems. On Posttest 1, 93% of the experimental group students responded correctly, in contrast to 39% of the control group. On Posttest 2, 39% of the experimental group responded correctly, in contrast to 0% of the Control group. The difference in performance on both posttests is statistically significant (p < 0.001). It is concluded that the teaching experiments facilitated students' understanding (progressive transitions) of electrochemistry.  相似文献

Abstract

This study examines the development of source evaluation skills in four groups of students from 10 to 19 years of age. We designed a set of tasks based on a distinction between three components of source evaluation: the identification of source parameters; the evaluation of source features such as the source’s competence or benevolence under explicit instructions; and the use of source features in assessing a document’s relevance with respect to a given task. This inventory was administered to 245 teenagers in grades 5, 7 and 9 and to undergraduate students. All types of source evaluation skills developed throughout adolescence, with some of them remaining suboptimal for older readers. Furthermore, we found weak relationships between students’ identification of source parameters and their use of source features in the absence of any specific prompt. Finally, source evaluation tasks were weakly related to teenagers’ word reading skills. Taken together, these results document teenagers’ acquisition of source evaluation skills and warrant a distinction between readers’ ability to comprehend source features and to use these features when assessing information quality.  相似文献

Many authoring tools have been proposed in an attempt to find more effective ways to face the challenge of developing educational software. However, most of them are reported to be restrictive, since they are strongly connected to a specific educational software development methodology. The AIDA (Ambiente Integrado para o Desenvolvimento de Aplicações educacionais) authoring environment was developed at the University of Coimbra having as its main objectives the support of most of the activities involved in authoring and making educational software development easier. The AIDA system is based on a design module, i.e. a prototyping tool allowing the creation of Windows-based software, including multimedia features. The system assists evaluation activities and it caters also for support on translation and cultural adaptation, as well as on the reutilization of educational materials. The use of the AIDA environment is illustrated by three small examples using different development methodologies.  相似文献

This study attempts to characterise what 7th- and 12th-grade students believe they do not know about artefacts and natural objects, as well as the dependence of what is unknown on a knowledge of these objects. The students were asked to make explicit through questioning what they did not know about a sample of objects. The unknowns generated were categorised according to a scheme based on lexical semantics theory. Two of the categories focused specifically on imprecise unknowns expressed through What is X? questions, and on unknowns concerning functions. The results showed, firstly, that a lower grade level and lower knowledge of a certain class of objects was associated with more imprecise unknowns. Secondly, unknowns about the functions of artefacts were significantly more frequent than unknowns about the functions of natural objects at any of the grade levels. Overall, the results were consistent with the hypothesis of a correspondence between knowledge and unknowns.  相似文献
