Developing plant identification skills is an important part of the curriculum of any botany course in higher education. Frequent practice with dried and fresh plants is necessary to recognize the diversity of forms, states, and details that a species can present. We have developed a web-based assessment system for mobile devices that is able to pose appropriate questions according to the location of the student. A student’s location can be obtained using the device position or by scanning a QR code attached to a dried plant sheet in a herbarium or to a fresh plant in an arboretum. The assessment questions are complemented with elaborated feedback that, according to the students’ responses, provides indications of possible mistakes and correct answers. Three experiments were designed to measure the effectiveness of the formative assessment using dried and fresh plants. Three questionnaires were used to evaluate the system performance from the students’ perspective. The results clearly indicate that formative assessment is objectively effective compared to traditional methods and that the students’ attitudes towards the system were very positive.  相似文献

In recent decades, higher education institutions worldwide have been moving from knowledge-based to competence-based curricula. One of the greatest challenges in this transition is the difficulty in changing the knowledge-oriented practices of teachers. This study evaluates the consistency between syllabus design and the requirements imposed by a competence-based learning environment. To make this comparison, the study sets four criteria (C1: explicit relationship between syllabus and graduate profile; C2: precision of the learning outcomes and assessment criteria; C3: contents that mobilise the learning outcomes; and C4: learning and assessment activities) derived from the literature and a thematic analysis of competence-based learning in higher education. Afterwards, a sample of 150 syllabi from different disciplines of five Chilean public universities were analysed, all of which stated the use of learning outcomes and competences in their learning models. Using a three-point Likert scale derived from the aforementioned criteria and their indicators, a comparison was made between the actual practices reflected in the syllabus design and the previously established criteria. Results show a gap between the declaration of a competency-based curriculum and actual syllabus outlines. Moreover, there are important differences among disciplines. Although all disciplines present high levels of accomplishment for Criteria 1 and 3, only the discipline of health sciences presents an acceptable level for Criteria 2 and 4. It is recommended that further research be undertaken towards identifying effective competency-based syllabus design.  相似文献

Abstract

In keeping with the theme of the 40th anniversary issue of EJTE, this article looks back and forward at US teacher education accountability. It argues that “holding teacher education accountable” has been the major approach to reforming teacher education in the US for the last two decades, assuming that enhanced teacher education quality depends on vigilant public evaluation and monitoring of outcomes related to teacher education institutions, programs, and teacher candidates. This article looks back at the “era of accountability” by examining five policy, political, and professional developments that contributed to its emergence and strong hold on US teacher education. Looking forward to the future of teacher education accountability in the US, the article argues that we need a new approach – democratic accountability in teacher education – which is based on intelligent professional responsibility for students’ learning including democratic knowledge and skills, strong equity, and genuine collaboration with multiple stakeholders.  相似文献

This paper focuses on the application of software engineering practices to the development of instructional web sites. The development of a web site, to support a distance or campus-based online course, is a very complex process that involves many instructional and technical aspects, including the instructional purpose of the course, its content, its structure, its interface, and its teaching–learning activities. The use of a method is essential for dealing with the complexity of this process. We describe, in this paper, a software engineering method that helps course designers and teachers to develop high quality instructional web sites. The design of the method was based on the integration of well-known principles, concepts and process models borrowed from instructional design, method engineering, and object-oriented software engineering. The method addresses the managerial processes required to plan, organize, and control the project, as well as the instructional and technical activities involved in the development of high quality course sites.  相似文献

This article explores the influence of Web-based corporate reporting on the investors' valuation of companies in the information and communications technology industry. This study compiled 8,111 news items issued in the “Press Releases” tab of the firms' Web sites between January 2003 and April 2005, and analyzed what type of news items affects stock returns. The results show a positive price reaction to news regarding new customers, completion of acquisitions, strategic long-term decisions, and non-technological alliances. In contrast, the results show a negative price reaction to news regarding the launch of new or upgraded products.  相似文献

Sustainable management of marine resources raises great challenges. Working with this socio-scientific issue in the classroom requires students to apply complex models about energy flow and trophic pyramids in order to understand that food chains represent transfer of energy, to construct meanings for sustainable resources management through discourse, and to connect them to actions and decisions in a real-life context. In this paper we examine the process of elaboration of plans for resources management in a marine ecosystem by 10th grade students (15–16 year) in the context of solving an authentic task. A complete class (N = 14) worked in a sequence about ecosystems. Working in small groups, the students made models of energy flow and trophic pyramids, and used them to solve the problem of feeding a small community for a long time. Data collection included videotaping and audiotaping of all of the sessions, and collecting the students’ written productions. The research objective is to examine the process of designing a plan for sustainable resources management in terms of the discursive moves of the students across stages in contextualizing practices, or different degrees of complexity (Jiménez-Aleixandre & Reigosa International Journal of Science Education, 14(1): 51–61 2006), understood as transformations from theoretical statements to decisions about the plan. The analysis of students’ discursive moves shows how the groups progressed through stages of connecting different models, between them and with the context, in order to solve the task. The challenges related to taking this sustainability issue to the classroom are discussed.  相似文献

ABSTRACT

Despite the importance of the theory of evolution (TE) to scientific knowledge, a number of misconceptions continue to be found among biology teachers. In this context, the first objective of this study was to identify the impact of professional development programme (PDP) on teachers’ understanding of nature of science (NOS) and evolution and on the acceptance of this theory. Its second objective was to study the relationship among these variables. Three instruments were used to quantify these variables: the Views of the Nature of Science Version D (VNOS D+), the Assessing Contextual Reasoning about Natural Selection (ACORN), and the Measure of Acceptance of Theory of Evolution (MATE). The results indicate that the PDP had a positive impact on teachers, significantly improving their understanding of the NOS and natural selection, as well as their acceptance of the TE. Furthermore, a positive correlation between the understanding of the NOS obtained by teachers in the first part of the PDP and the understanding and acceptance of evolution that these teachers showed at the end of the programme was determined. However, no relationship between an understanding of the NOS and gains in the understanding and acceptance of evolution was found.  相似文献
