Software Support for Team Engineering: Educational Case for IT Students 团队工程的软件支持:IT学生的教育案例
O. Zvereva, S. M. Riad Shams
Every scientific project is a result of efforts of professionals from different working areas on the basis of their combined knowledge implementation. In the view of a team work significance for IT professionals, team work was proposed for one course from IT educational programme as the main active learning method. To engineer effective teams, SNA-methodology was implemented. The results of this implementation were discussed in the classes as an example of information technology and corresponding software tool usage for a real problem solution. A comparative analysis of two different tools was carried out, which has yielded in one more educational effect. This example of integrated learning which involve students both into professional and scientific activity was proved to be useful for educating real IT specialists.
每一个科学项目都是来自不同工作领域的专业人员在综合知识实施的基础上共同努力的结果。鉴于团队合作对IT专业人员的重要性,我们在IT教育计划的一门课程中提出了团队合作作为主要的主动学习方法。为了设计有效的团队,实施了sna方法。这个实现的结果在课堂上作为信息技术和相应的软件工具使用的一个实际问题解决方案的例子进行了讨论。对两种不同的工具进行了比较分析,这又产生了一种教育效果。这个将学生纳入专业和科学活动的综合学习的例子被证明对培养真正的IT专家是有用的。

VUZ: A Crowdsourced Framework for Scalable Interdisciplinary Curriculum Design VUZ:可扩展跨学科课程设计的众包框架
E. J. Azofeifa, G. Novikova
Higher education in traditional, highly centralized institutions is struggling to adequately prepare professionals in accordance to the current job environment, where demonstrating abilities to quickly adapt to changes and learn new skills is progressively gaining weight against solely holding a college degree, for example. Elevated tuition costs is another factor pushing people into short, internet-based specialized courses or directly into the job market, while an increasing number of people holding full degrees are underemployed in respect to their knowledge level. We propose VUZ, a domain-general framework capable of tackling these issues by designing personalized curricula from a high-level perspective (general courses, subjects and topics) down to specific how to's and step-by-steps, by means of crowdsourcing: delegating the curriculum development to a community of experts. The framework is scalable in the sense that individuals can choose the level of refinement of their curriculum depending on their prior knowledge; is decentralized in the sense that all decisions are taken by the users; and is collaborative because of the possibility of sharing knowledge with other users. We detailed the crowdsourcing algorithm used for curricula development and simulated a VUZ platform using a multiagent system, which yielded a series of cost and retribution results associated to potential users of a VUZ system.
传统的、高度集中的高等教育机构正在努力根据当前的工作环境为专业人员做好充分的准备,在这种环境中,展示快速适应变化和学习新技能的能力逐渐变得比仅仅拥有大学学位更重要。学费上涨是另一个促使人们选择短期的、基于互联网的专业课程或直接进入就业市场的因素,而越来越多拥有完整学位的人在他们的知识水平方面处于就业不足的状态。我们提出了VUZ,一个能够解决这些问题的领域通用框架,通过众包的方式,从高层次的角度(普通课程、科目和主题)设计个性化课程,直到具体的方法和步骤,将课程开发委托给专家社区。这个框架是可扩展的,因为个人可以根据自己的先验知识选择课程的细化程度;是去中心化的,因为所有的决定都是由用户做出的;它是协作的,因为它有可能与其他用户分享知识。我们详细介绍了用于课程开发的众包算法,并使用多智能体系统模拟了一个VUZ平台,该平台产生了一系列与VUZ系统潜在用户相关的成本和报应结果。

The Use of Interactive Methods and Computer Technologies for Increasing the Motivation for In-Depth Study and Obtaining Long-Term Knowledge in the Course Theoretical Foundations of Electrical Engineering 在《电气工程理论基础》课程中,运用互动方法和计算机技术增加深入学习和获得长期知识的动力
Kozmina Irina, M. Roman, M. Olga
When preparing competitive specialists during the study, students should develop the initiative with a creative approach, leaning against on active use of interactive and computer methods jointly with multimedia information technologies. The stages of formation of long-term knowledge as example of studying the course of “Theoretical Foundations of Electrical Engineering” in the “NRU “MPEI”” at the department of TFEE using application programs Matlab, Simulink, Delta profe, ELCUT considered in the article. These programs allow save students' time significantly in the performance of laboratory works, typal calculations and make possible of math modeling for more in-depth study of subject. Formation of research skills, developing the ability to analyze the situation and take optimal decision play a particular role in teaching students. Students studying according to offered methodology, during three terms had been modeling and calculating the set tasks using the applied packages of programs of Matlab, Simulink, Delta profe, ELCUT. Such approach contributed to the deeper immersion of students in the educational process and the acquisition of knowledge necessary for obtaining and improving professional skills in the chosen field.
在培养有竞争力的专业人才的过程中,学生应该以创造性的方式发展主动性,积极利用互动和计算机方法与多媒体信息技术相结合。本文以TFEE系“NRU”MPEI“电气工程理论基础”课程为例,利用Matlab、Simulink、Delta profe、ELCUT等应用程序研究了长期知识的形成阶段。这些程序可以大大节省学生在实验室工作、典型计算方面的时间,并使数学建模成为可能,以便更深入地研究学科。研究技能的形成、分析形势和做出最佳决策的能力在教学中发挥着特殊的作用。根据所提供的方法,学生在三个学期中使用Matlab、Simulink、Delta profe、ELCUT等应用程序包对所设置的任务进行建模和计算。这种方法有助于学生更深入地沉浸在教育过程中,并获得在所选领域获得和提高专业技能所需的知识。

Learning System Thermopr@ctice for the Calculation of Exercises with Mathcad 用Mathcad计算习题的学习系统Thermopr@ctice
H. Kretzschmar, S. Herrmann, M. Schneider, I. Jaehne
The learning system Thermopr@ctice represents an internet-based learning environment for calculating exercises using the computer algebra system Mathcad. This new working method for the learner consists of replacing the conventional paper worksheet with the Mathcad working screen. The exercises-here for those learning Technical Thermodynamics-are provided to the learner via the internet in individual variations and with individual numerical values in the Mathcad format. The exercises are solved during supervised seminars or on the computer at home. The teaching materials which are necessary for the solution are provided in Mathcad format. After calculating each subtask, the learner sends the solution to Thermopr@ctice. If an error occurs, the system will request interim results. The learning system takes the students closer to modern working methods in the workplace by using a computer algebra system and subject-related property libraries. Since the system has been designed for the purpose of self-study, it is particularly suitable for further education and distance learning. It can be applied to other subjects in which the acquisition or consolidation of knowledge takes place by calculating exercises. Thermopr@ctice was developed within the scope of the joint research project “Saxon Education Portal” from the Saxon Ministry of Science and Art and since then it has been continuously improved and enhanced.
学习系统Thermopr@ctice代表了使用计算机代数系统Mathcad计算练习的基于互联网的学习环境。这种新的学习方法包括用Mathcad工作屏幕取代传统的纸质工作表。这些练习——这里是为那些学习技术热力学的人准备的——通过互联网以不同的形式提供给学习者,并以Mathcad格式提供不同的数值。这些练习可以在有指导的研讨会上或在家里的电脑上解决。本文以Mathcad格式提供了解决问题所需的教材。在计算完每个子任务后,学习器将解决方案发送到Thermopr@ctice。如果发生错误,系统将请求临时结果。该学习系统通过使用计算机代数系统和与学科相关的属性库,使学生更接近工作场所的现代工作方法。由于该系统是为自学而设计的,因此特别适合继续教育和远程学习。它可以应用于其他科目,在这些科目中,知识的获取或巩固是通过计算练习进行的。Thermopr@ctice是在撒克逊科学和艺术部联合研究项目“撒克逊教育门户”的范围内开发的,从那时起,它不断得到改进和加强。

Assessment of Qualification of University Graduates on the Basis of Fuzzy Graph Approaches 基于模糊图法的高校毕业生资格评价
N. Sergeev, A. Kolodenkova, E. Muntyan
In article is considered complex assessment of qualification of graduates of higher educational institutions on the example of the Samara state technical university (Samara Polytech). The model of the fussy hypergraph, which considers about 50 parameters influencing assessment of qualification of the graduate, is used. The model can be considered with various degree of a detail. The algorithm of absorption of the hypergraph for the purpose of reduction of number of parameters (tops) which works in real time is applied to change of scale of model. At the same time the reversibility of operation of absorption is noted. Transition from scalable model to fuzzy cognitive model which is realized in the form of an orgraph of assessment of factors of professional development of the graduate is executed. The system indicators of fuzzy cognitive model allowing to reveal what of factors exert the greatest impact on obtaining qualification of the graduate are calculated and also to estimate extent of influence of one factor on another.
本文以萨马拉国立技术大学(萨马拉理工大学)为例,讨论了高等教育机构毕业生资格的复杂评估。采用模糊超图模型,考虑了影响毕业生资格评价的约50个参数。该模型可以考虑不同程度的细节。将实时工作的超图吸收算法用于模型尺度的变化,以减少参数数目。同时指出了吸收作用的可逆性。实现了从可伸缩模型到模糊认知模型的过渡,实现了对毕业生专业发展因素的评价。计算了模糊认知模型的系统指标,揭示了哪些因素对毕业生获得资格的影响最大,并估计了一个因素对另一个因素的影响程度。

The model of the fussy hypergraph, which considers about 50 parameters influencing assessment of qualification of the graduate, is used. The model can be considered with various degree of a detail. The algorithm of absorption of the hypergraph for the purpose of reduction of number of parameters (tops) which works in real time is applied to change of scale of model. At the same time the reversibility of operation of absorption is noted.
