The computer registration of physical and mechanical quantities gives a lot of possibilities for machine elements and mechanisms research. The advantages of well-organized computer laboratory both technical and methodological are namely: registration and on-line observation of a number of processes with random speed; replacement of high-cost specialized laboratory equipment; mathematical data processing; solving educational problems by modern technologies.
The purpose of this paper is to present the results of implementation of universal computer system for registering physical and mechanical quantities of elastic coupling, prepared in the laboratory of Machine Elements at the Higher School of Transport, Sofia, Bulgaria. The results are obtained by a special stand and the quantities are registered by a universal interface and software. After mathematical processing a number of characteristics and properties important for practice, such as diagram of friction and dumping in the coupling, shaft angle speed, etc. have been obtained.
The interface and software used allow to students to make the electrical scheme of measuring by them, to acquire basic knowledge for the problem investigated and to acquire self-confidence of solving such problems in practice.
A project is being developed with the main goal of creating an application of web server which allows students to use Mathematica software from their computers without the necessity of installing this software and of programming the necessary algorithms. The project consists of a set of mathematical models programmed with Mathematica and stored in a web server, which has been installed in a computer of our department. At the moment, it is possible to access to the web pages of the application from any computer of the intranet of our School.
The article examines update of modules of general IT (Informatics) studies under changes in secondary school programs. It is proposed to create distance-learning courses and use ``tools set'' principles. It will allow broadening the choice of study subjects and will create possibility for students from different faculties to choose the subjects and realization tools that better meet their needs and fields of studies. The developed materials will be available to all students and staff willing to improve IT skills through distance learning. Tasks and knowledge control will be unified in the whole University. The materials of updated Informatics courses will be presented in a virtual learning environment WebCT, including self-control tasks and tests. This will also be very useful for correspondence students.
Distance learning involves a lot of work of human assistants. These assistants need to be connected for answering student doubts and questions. Intelligent agents can do part of this repetitive work because they can observe students interacting with educational courses, detect learning troubles of these students, and then suggest them some way for overcoming those troubles. However, a design problem appears with this promised possibility: how to connect educational applications with these agents. This paper presents a solution to this problem, in which both the capture of student's intentions and agent intervention for helping students are specified. These two architectural design points are defined as connection points. The first connection point is named student intentions. Student intentions define situations in which agents might help. This connection point depends on the user interface of the educational application that students are using; the agent needs to know the gestures that students could do for interpreting their intentions. The second connection point is named agent interventions. Agent interventions define the context in which agent might assist and the type of help that might give, like a suggestion or a warning. This solution is introduced in the context of one specific application for distance learning named SAVER, which is used for exemplifying each architectural design point.
Many factors influence teaching nowadays. Numbers of students are increasing, some students pay for studies and require more flexible teaching, more students have access to Internet, the learning material is changing rapidly (especially of subjects, related to information technologies), publishing industry is slow and expensive. All that stimulates usage of modern technologies in education. Virtual Learning Environments (VLEs) is one of the forms of e-learning. They open new ways of teaching and communication such as management of online learning, course delivery mechanism, communication and assessment tools, student tracking, access to electronic resources, etc. All these means correspond to the needs of contemporary teachers and students. VLEs have primarily been used for distance education but they are being used increasingly as supplement of traditional classroom based education. The author is interested in this latter aspect of VLEs.
The paper briefly reviews main types of Virtual Learning Environments and analyses the use of VLEs in Lithuania. The results of the investigation of two different learning environments - traditional (Web CT) and collaborative (FLE3) at the Vilnius Pedagogical University are also discussed in the article.
