This paper shows how concept mapping can be used to measure the quality of e‐learning. Six volunteers (all of them 3rd‐year medical students) took part in a programme of e‐learning designed to teach the principles of magnetic resonance imaging (MRI). Their understanding of MRI was measured before and after the course by the use of concept mapping. The quality of change in individuals' maps was assessed using criteria developed to distinguish between meaningful and rote‐learning outcomes. Student maps were also scored for evidence of conceptual richness and understanding. Finally, each map was compared directly with the content of the electronic teaching material. The results show that many of the student misconceptions were put right in the course of their learning but that many of the key concepts introduced in the teaching were ignored (or sometimes learnt by rote) by the students. This was because the teaching material locked these new ideas in structures and terminology that precluded meaning‐making among non‐experts. Our data suggest that students' prior knowledge is a key determinant of meaningful learning. We suggest that this must be acknowledged if the design and use of electronic teaching material is also to be meaningful. Ultimately, measures of student learning are the only authentic indicators of the quality of teaching through technology. 相似文献

The purpose of this study was to assess Greek primary (1st to 6th grade) school children's understanding of sun exposure during summer vacation. Our results show that children know the damaging effects of long time exposure and the precautions that should be taken during sun bathing (sun glasses, hat, umbrella, sunscreen, etc). Nevertheless, they do not seem to avoid being exposed between 12.00 A.M. and 15.00 P.M., which is the most dangerous time. The socioeconomic status of father has no effect on the attitude of children towards taking protection measures when exposed to the sun, however, the educational status of the mother appears to influence children's reported knowledge and behaviour. Place of residence (urban or rural areas) and gender does not influence their knowledge on the sun's damaging effects and the precautions they should take. Finally, as children grow older they seem to gradually reduce the protective measures they take. 相似文献

The purpose of this study was first to assess and then to improve the diet of Greek primary school children teaching them healthy dietary habits and instructing them to face critically advertisements and media projected dietary models using a program which included intervention on cognitive, emotional, and social level. The results show that our intervention was more effective on the cognitive level and in particular on children's ability to estimate the dietary value of different kinds of food. However, their food preferences were not affected significantly, suggesting that these are more resistant to change since they are already consolidated and, therefore, need longer intervention. 相似文献

This paper tries to describe the effects of media modernization and commercialization in journalism and politics, taking as example the case of contemporary Greece. This paper is organized into two parts. The first deals essentially with the effects that the new structure of the Greek media system has imposed on professional journalism, while the second deals with the changes that this new media environment has caused in the political world. It argues that these changes have led to a new battle between the media owners and politicians over who will control the public and political agenda and a new relationship between them. 相似文献

Purpose: The objective of the present study was to compare the learning efficiency of two information and communications technology (ICT)-based instructional strategies (multimedia presentation (MP) and concept mapping) in a sample (n?=?187) of Greek sheep farmers operating mainly in Western Greece. Design/methodology/approach: In total, 15 instructional sessions have taken place. The knowledge assessment of the farmers, before and after the instructional interventions, was based on answers given to five questions of graded difficulty and the SOLO (Structure of Observed Learning Outcomes) taxonomy. Findings: The two instructional strategies showed comparable learning outcomes. Furthermore, prior participation to training sessions as well as the participants’ advanced education level enhanced the learning outcome. Practical implications: Simple applications of ICTs such as MPs and concept maps can be exploited in sheep farmers’ training. Special attention has to be paid to the content and the context of the digital learning material. Originality/value: The study contributes to the lack of evidence regarding the assessment of learning outcomes of instructional strategies assisted by digital learning environments in livestock farmers. 相似文献

Following ingestion of either water (Experiment 1) or saccharin (Experiment 2), experimental groups of rats were poisoned with lithium chloride and acquired an aversion to the ingested fluid. This aversion gradually extinguished and, in both experiments, was not reacquired when fluid intake was again followed by poisoning. These results are in marked contrast to usual findings of very rapid relearning following extinction with conditioning preparations other than taste-aversion learning. 相似文献

The paper explores the relationship between formative assessment and social software. Formative assessment practices though beneficial for student learning become marginalised and constrained in open and distance learning environments in higher education. Feedback is a key factor in formative assessment and learners can benefit from the deployment of emerging technologies and the opportunities for participation and dialogue afforded by social software. This paper explores and proposes a conceptual framework for this relationship. The claim is that the social dimensions of emerging technologies – specifically, blogs and wikis – allow for formative assessment practices to be re‐invented or at the very least facilitated by essentially participative and student‐focussed interventions. A comparison of these technologies against formative assessment mechanisms identifies the types of processes that these new tools might best support to encourage effective feedback approaches that both empower the learner and enhance their learning experience. 相似文献
