This article discusses effective mechanisms that enable a group of robots to autonomously generate, adapt, and enhance team behaviors while improving their individual performance simultaneously. Two promising team learning concepts, namely, cooperative learning and advice‐sharing, are integrated to provide a platform that encompasses a comprehensive approach to team‐performance enhancement. These methods were examined in relation to the performance characteristics of standard single‐robot Q‐learning to ascertain whether they retain viable learning characteristics despite the integration of individual learning into team behaviors. 相似文献

Quartz crystal oscillators for many radio frequency (RF) applications must provide a high‐frequency stability in a wide temperature range. To do this, a temperature compensation network is commonly included. This study analyzes and determines the frequency behavior of an oscillator circuit with variations in temperature and shows how simulation may be employed for the design of high‐stability quartz crystal oscillators. © 2001 John Wiley & Sons, Inc.

This paper reports an investigation into the effects of collaborative concept mapping in a digital learning environment, in terms of students' overall learning gains, knowledge retention, quality of student artefacts (the collaboratively created concept maps), interactive patterns, and learning perceptions. Sixty‐four 12‐year‐old students from two 6th grade classes (32 from each class) participated in the study. Guided by the methodology of quasi‐experimental research, group scribbles 1.0 was adopted in which students carried out collaborative concept mapping activities for social studies in two different settings: (1) 1:1 (one‐device‐per‐student) – students working in pairs with one Tablet PC assigned to each of them; and (2) 1:m (one‐device‐to‐many‐students) – multiple students sharing a Tablet PC. Both settings were evaluated and the interactional patterns of the student groups' concept mapping were identified. The results indicated that in both 1:1 and 1:m settings, students had improved their learning results and retention. Nevertheless, while 1:1 groups had demonstrated more consistency in group participation, improved communication and interaction, the 1:m groups had instead generated superior artefacts as all the notes were well discussed among the group members. The findings suggest that a higher quality of collaborative processes does not necessarily lead to improved student artefacts. 相似文献

在分布式合作学习环境中,学生和老师需要一个共享的信息空间去与学习材料交互作用,并从中知晓合作者的存在及其活动.学生和老师还需要一些协同和通信手段去协调他们共同的活动.为此,提出了一种视觉化协同超媒体技术.它可以提供所需的共享信息空间.在此空间中,形象的超媒体对象既可以表示学习材料(学习内容),又可以表示学习过程(学习方法).这种协同超媒体集成了灵活的过程支持、通信渠道以及文件处理功能.因而,它可以支持学生(和老师)按一定的学习方法并通过文字或声音渠道去协调他们共同的学习活动.这种协同超媒体可以通过万维网(浏览器)访问.为了揭示这种技术的实用性,还给出了一个案例和一些用户体验. 相似文献

The aim of this study is to test collaborative concept mapping activities using computers in a classroom scenario and to evaluate the possibilities that Elkar-CM offers for collaboratively learning non-technical topics. Elkar-CM is a multi-lingual and multi-media software program designed for drawing concept maps (CMs) collaboratively. Concept mapping is a widely accepted technique that promotes meaningful learning. Graphically representing concepts of the learning domain and relationships between them helps students integrate new knowledge into their current cognitive structure. This study was carried out with Social Education degree students at the University of the Basque Country (UPV/EHU). The experiment included two learning activities. First, all students collaboratively constructed in the classroom a CM on the subject of Moral Development. Second, students were organised into groups to complete the CM generated in the first part. 相似文献

A gap exists between students' employment needs and higher education offerings. Thus, developing the capability to meet the learning needs of students in supporting their future aspirations should be facilitated. To bridge this gap in practice, this study uses multiple methods (i.e., nominal group technique and instructional systems development) and robust tests (e.g., reliability and validity) to develop a diagnosis system of work‐related capabilities. The research participants are twofold. At the early stage, this study invites three professors and three senior Human Resources managers to join the panel and help this study develop required capabilities. At the design and implementation stages, the research participants are freshman students at a famous university in Taiwan. This system enables college students to evaluate their capability scores by comparing themselves with the performances of prior students. The diagnosis results not only help students make learning plans during their university education, but also assist educators in adjusting the structure of the curriculum. Future studies are invited to use or adapt the assessment of work‐related capabilities, as well as proposed system procedure and architecture this study developed. 相似文献

Abstract Mobile technologies offer the opportunity to embed learning in a natural environment. This paper describes the design of the MobileGame prototype, exploring the opportunities to support learning through an orientation game in a university setting. The paper first introduces the scenario and then describes the general architecture of the prototype. The main part of the paper focuses on the evaluation of design issues and the effects observed in two trials. Design issues include: Supporting work on the move poses difficult interface questions, the accuracy of current outdoor, and indoor positioning systems is still problematic and the game requires near real-time response time. The evaluation of the effects shows that features such as ‘map-navigation’ and ‘hunting and hiding’ lead to excitement and fun. The participants immerse into a mixed reality that augments both physical and social space. The game success is based on the motivating design of the game itself. The paper concludes with open issues for future research, especially with the need to thoroughly evaluate the learning benefits. 相似文献

Team‐based learning (TBL) stresses applying knowledge rather than absorbing knowledge in class; studies have investigated the use of TBL and its merits in different teaching courses (e.g., medical science and business). TBL is most effective when students learn autonomously before class. However, the ability of autonomous learning is highly associated with the ability of self‐regulated learning (SRL); most importantly, not every student possesses good (or high) SRL ability. Nevertheless, few studies have compared the effectiveness of TBL in students with different SRL abilities. To address this issue, this study analyzed approximately 90 students, whose course teaching involves office application software (Microsoft Excel). This study also developed an online TBL system (called Online TBL) to facilitate performing TBL and to collect the learning behaviours of students with different (high or low) SRL abilities on each TBL stage. The analytical results show that compared with the low‐SRL students, the high‐SRL students were more prepared for class because they spent more reviewing material and had better scores on personal uploaded Excel and Individual Readiness Assurance Test. From the feedback of the peer evaluation, the results also show that the high‐SRL students received more credits than the low‐SRL students did. The questionnaire survey revealed that both low‐SRL and high‐SRL students had a favourable impression of TBL. Further discussion is given to explain the above results. 相似文献

This work explores potential errors arising in the application of modern computer‐aided engineering (CAE) software to the simulation of RF‐communication system hardware. A hardware set comprising a 915‐MHz transmitter and a corresponding 915‐MHz receiver is analyzed by comparing system‐level simulations from commercially available software to various linear and nonlinear performance measurements. It is shown that after the determination of the subsystem computer‐aided design parameters using the measured component behavior, good predictions of in‐band performance can be achieved for all analog parameters examined. Discrepancies, in some cases significant ones, are revealed in the out of band response predictions of the output frequency spectral content caused by system nonlinearities. Ideal filter and mixer models, in particular, are shown to be inadequate for high accuracy system simulation work. © 2003 Wiley Periodicals, Inc. Int J RF and Microwave CAE 13: 86–100, 2003. 相似文献
