The objective of this study was to construct a teaching strategy for facilitating students’ conceptual understanding of the
boiling concept. The study is based on 52 freshman students in the primary science education department. Students’ ideas were
elicited by a test consisting of nine questions. Conceptual change strategy was designed based on students’ alternative conceptions.
Conceptual change in students’ understanding of boiling was evaluated by administering a pre-, post- and delayed post-test.
The test scores were analysed both by qualitative and quantitative methods. Statistical analysis using one-way ANOVA of student
test scores pointed to statistically significant differences in the tests and total scores (p < 0.05). Quantitative analysis of students’ responses on each test revealed different schema about changing their knowledge
system. Both qualitative and quantitative analyses suggest that the teaching activities facilitated students’ conceptual understanding.
No statistically significant differences were found between post-test and delayed post-test scores, suggesting that the teaching
strategy enabled students to retain their new conceptions in the long-term memory. 相似文献

The Opera eLearning project developed a solution for opera singing distance lessons at the graduate level, using high bandwidth to deliver a quality audio and video experience that has been evaluated by singing teachers, chorus and orchestra directors, singers and other professional musicians. Prior to finding a technological model that suits the user's requirements, several experiments have been conducted, testing and prototyping different technologies, until arriving at a telepresence, immersive sound model. This paper summarises the findings of this pilot stage, and its interest includes the management of innovation exercises across a multidisciplinary team, based on usability and a user-centred design. Some of the technology tested includes professional audio and video equipment, software for A/V signal capturing and transmission on uncompressed formats, A/D converters, and other auxiliary devices. The resultant model has later been successfully used in a formal case study, delivering 14 remote masterclasses. 相似文献

The online interaction of learners and tutors in activities with concrete objectives provides a valuable source of data that can be analyzed for different purposes. One of these purposes is the use of the information extracted from that interaction to aid tutors and learners in decision making about either the configuration of further learning activities or the filtering of learning resources. This article explores the use of an affiliation network model for such kind of purposes. Concretely, the use of techniques such as blockmodeling – a technique used to derive meaningful patterns of relationships in the network – and the analysis of m-slices – a technique helpful to study cohesion in relationships – are explored as tools to decide on the configuration of topics and/or learner groups. In particular, the results of the case study show that such techniques can be used to (i) filter participants for rearranging groups; (ii) rearrange topics of interest; and (iii) dynamically change the structure of a course. The techniques presented can be considered a case of collaborative filtering based on social network structure. 相似文献

The widespread adoption of computers and Internet in our life has reached the classrooms, where computer-supported collaborative learning (CSCL) based on wikis offers new ways of collaboration and encourages student participation. When the number of contributions from students increases, traditional assessment procedures of e-learning settings suffer from scalability problems. In a wiki-based learning experience, automatic tools are required to support the assessment of such huge amounts of data. In this work, we present StatMediaWiki, a tool that collects and aggregates information that helps to analyze a MediaWiki installation. It generates charts, tables and different statistics enabling easy analysis of wiki evolution. We have used StatMediaWiki in a Higher Education course and present the results obtained in this case study. 相似文献

The use of dissection to study human anatomy is the foundation for educational excellence among future health professionals, as it offers an ideal opportunity to learn the body's morphology in three dimensions while also providing students with a more humanistic education. The shortage of bodies for dissection, combined with the Brazilian population's lack of knowledge concerning the possibility of voluntarily donating their own bodies, led to the creation of the Body Donation Programs for Education and Research in Anatomy at the Federal University of Health Sciences of Porto Alegre (UFCSPA). The program is based on three pillars: Informing the general public about the program, donor registration, and donation itself. Since the creation of the donor program in 2008, there has been an increase in both the number of donations made during donor's lifetime and the number of bodies received by the university. There has also been a shift in relation to the origin of these bodies, as before the creation of the program most bodies were unclaimed cadavers, while today most of the bodies are sourced from voluntary donations. The initial results regarding the public's acceptance of the possibility of making body donations have been encouraging, as shown by the annual growth in donor registrations. Consequently, the quality and quantity of the material available for educational purposes have greatly improved. Anat Sci Educ. © 2013 American Association of Anatomists. 相似文献

In March 2012, 30 faculty and 49 students from all over the world met in El Calafate, Argentina, during two intense weeks. It was the second Latin American School for Education, Cognitive, and Neural Sciences (LASchool), sponsored by the James S. McDonnell Foundation. The LA School seeks to critically examine research findings potentially relevant to the development, design, and implementation of effective educational practices, and to foster a new generation of researchers able to operate at the interface between education and science. Here we introduce a special issue which brings together theory, experiments, and educational interventions which emerged from ideas presented and discussed during the 2012 LASchool. 相似文献

Part‐time study is one of the foci of the widening participation agenda in the UK. The experiences of part‐time students, however, have received remarkably little attention from scholars, especially in a comparative context. This paper explores existing historical data going back over a decade to identify the main themes of part‐time experience at a number of UK higher education institutions and how it compares and contrasts with the full‐time experience. The surveys use the Student Satisfaction Approach. The main themes emerging from institutional survey data over time are the work/family/study balance, assessment and feedback, access to learning and catering resources, and students' financial situation. There is sometimes a question of identity, but unlike many studies of part‐time student experience, which focus on aspects of disadvantage, social, and cultural capital, the data for this paper indicate that many part‐time students have a sense of themselves as being ignored or at worst marginalised in contemporary higher education. 相似文献
