随着电子课本与电子书包项目的示范应用深入推进,市场上出现了越来越多且形式各异的电子课本。电子课本国家标准正在制定过程中,相关标准草案界定了电子课本,但其属性与"电子书"和传统的"教科书"的特性存在交叉与融合。文章从"电子书"和"教科书"的角度出发,对电子课本的概念、属性、特性和功能进行系统剖析,利用概念地图工具、Wiki百科共建知识的方法,明确电子课本的术语概念,将电子课本的特性与属性区分开来,并进行对应分析,以更好地揭示电子课本的内涵,完善电子课本相关标准草案,推进电子课本的应用。  相似文献

目前,学界对于冒用他人信用卡在ATM(自动取款机)上取款行为的性质认定主要存在两种观点,一种观点认为此行为属于盗窃性质,应当以盗窃罪定罪;另一种观点认为此行为属于诈骗性质,应当认定为信用卡诈骗罪。本文通过对银行客户服务终端和用户密码法律地位的分析,认为应当将ATM视为银行的电子代理人,冒用他人信用卡在ATM上取款的行为应当认定为信用卡诈骗罪。  相似文献

Trading cards for various sports and a range of other subjects such as architecture, animals, hobbies, and war have been in existence since the late nineteenth century and still enjoy great popularity. Two of the most prominent examples are baseball cards in the U.S. and football cards in Europe. Three strategies for collecting European football trading cards were investigated for two different groups: either a single collector or two collectors joining forces. An activity is proposed in which students use a simulation to compute the factor by which the number of trading cards bought exceeds the number to be collected. This enables them to estimate the expected costs of completing a collection of trading cards. The overall expected costs vary considerably, depending on the strategy used. Savings for a team of two collectors as opposed to a single collector are indicated.  相似文献

This article explores students' perceptions of how their input on 'reaction cards' affected their classes. Reaction cards - index cards upon which each student writes remarks related to each day's class activities - were used in 10 classes across seven disciplines as a means of formative evaluation. Open-ended survey questions about the reaction cards were completed anonymously by 195 students at mid-term and by 184 students at the end of the semester. Faculty also reported on how they used the cards and their perceptions of how the cards impacted their classes. At mid-semester, students indicated that the cards had a positive impact on their classes. The cards improved communication, increased students' involvement in the course, and improved their connection to the material. At the end of the semester there were some negative comments related to the tedium of filling out the cards in each class. Reaction cards can provide a simple but powerful tool for gathering data that can be used to modify and improve courses as they progress.  相似文献

This is the report of a five month study, undertaken by Sundridge Park Training Technologies in association with Guildford Educational Services to assess the potential of smart card technology to support learning and the management of learning. The study had two strands—the state of the art of the technology and its potential for supporting, delivering and managing learning. In addition to a study of the literature and extensive discussions with people using smart cards, potential users of smart card and visionaries, the project team developed two illustrative systems using cards to store personal data relating to education and training. The term ‘smart card’ is often used loosely to describe three different types of card, each of which is similar in general shape and size to a traditional credit card. These are: memory cards, laser cards—and true smart cards incorporating a processor and memory. This study has been concerned with memory cards and smart cards. The focus for smart card applications has been predominantly financial: there are relatively few applications in education or training. A notable exception is the large scale project at the University of Bologna which uses smart cards to manage the progress and achievements of a large number of students in the Department of Electronics. The two illustrative systems provided valuable experience of using memory cards and smart cards in quasi‐real education and training applications. They highlighted the problems of limited memory capacities and confirmed the high level of user acceptance reported by other trials. We can expect considerable advances in the technology of both memory cards and smart cards over the next months and years. The memory capacities of both types of cards will increase many‐fold and the unit costs will fall as large quantities of cards are produced for financial applications. Education and training applications will benefit from this expanding market. The major surprise from the study was the level of interest in the work and the enthusiasm expressed by almost all of those who came to hear of it. The general level of awareness of smart card technology was found to be low. However, the requirement for a system which will enable individuals to manage and own their learning on an extended timescale was generally recognised. Some of the possible applications for smart cards and memory cards in education and training had emerged before the official start of the study and it is clear that the technology is potentially pervasive. The project team and those consulted identified a wide range of possible applications both in education and in training. These focussed on assessment, personal course planning and management, identification of relevant learning opportunities, and the ownership of learning. It was felt that, over the next few years, smart cards are very likely to be in common use as credit cards for financial applications. Therefore, their use for education and training should be planned now. The recommendations from the study are that: More detailed studies are needed to find out how smart cards and memory cards could be used by different organisations in a fully operational system; Standards should be established for smart card applications in education and training, similar to those governing financial applications; Applications should be developed after the standards have been established. To be convincing, these should take a case study approach with small pilot studies in a variety of contexts and must follow real needs rather than attempt to drive them; The case studies would then form the basis for a campaign to increase awareness of smart cards and their potential for education and training, together with a programme for building an infrastructure to support the proposed systems. The public sector should fund the task of developing standards and providing interfaces with existing educational systems and projects to demonstrate the feasibility of various applications. Since educational standards have a European dimension, the European Community may be a source of support for work in the area of standards. At the same time, private sector funding should be sought for skill development and career development systems in industry and in education. The Training Agency itself should consider the application of smart card technology to the control and management of the Youth Training Scheme (YTS).  相似文献

Prescribed active learning increases performance in introductory biology   总被引:4,自引:0,他引:4  
We tested five course designs that varied in the structure of daily and weekly active-learning exercises in an attempt to lower the traditionally high failure rate in a gateway course for biology majors. Students were given daily multiple-choice questions and answered with electronic response devices (clickers) or cards. Card responses were ungraded; clicker responses were graded for right/wrong answers or participation. Weekly practice exams were done as an individual or as part of a study group. Compared with previous versions of the same course taught by the same instructor, students in the new course designs performed better: There were significantly lower failure rates, higher total exam points, and higher scores on an identical midterm. Attendance was higher in the clicker versus cards section; attendance and course grade were positively correlated. Students did better on clicker questions if they were graded for right/wrong answers versus participation, although this improvement did not translate into increased scores on exams. In this course, achievement increases when students get regular practice via prescribed (graded) active-learning exercises.  相似文献
