3.2 Choice of a platform of implementation
For operation over the textbook the editor of the Notepad language ++, by Dreamviewer as the most widespread editor for operation in the HTML format was used. Such choice is confirmed by the general practice of application of electronic textbooks. Perspective of such approach is display in different operating systems and browsers on their basis.
Thus, there is a necessary cross-platform of the textbook.
Not a secret that recently there are various attempts to transfer computer classes of educational institutions from the MS Windows operating system on operating systems of the Linux series.
And the HTML language as a hypertext cross-platform programming language allows to remain independent in this sense.
3.3 Structural matrix of the electronic textbook on the discrete mathematics
The main document confirming and allowing to confirm originality of development is the matrix of the electronic textbook. By development she allows to consider structurally the textbook and to trace notes of users, students and to develop the textbook.
3.4 Composition of the main chapters of the electronic textbook
Sets of computer experiments and manuals — the integral methodical system providing both demonstrations and laboratory operations, and independent project creativity. They are especially important at the beginning acquaintances of the teacher to the program, helping to master quicker it and to enter into educational process not incidentally, and as the thought-over system.
3.4.1 Heads the devoted theories of sets
The initial concept of the theory of sets is the concept a set as which it is accepted to understand some set of objects, well perceptible our thought or intuition. Thus doesn't become any assumptions neither of the nature of these objects, nor of a method of their switching on in this set. The separate objects making this or that set, call elements of this set. Question "Why we consider this or that set of elements as a set? " doesn't require the response as in the general determination of a set no additional conditions on switching on of separate elements enter a set. If we want to consider, for example, the set consisting of three elements: "the sun, the sea, orange", nobody will be able to forbid it to make.
3.5 Development of systems of testing and monitoring of knowledge of pupils
Interest to testing systems and monitoring of knowledge of the pupils, provided in the market of the specialized software (S), permanently increases. The modern the software of a considered class, as a rule, supports four types of tests:
1 . Choice of the correct answer on a question from a set available (a single choice and/or a multiple selection).
2 . The correct installation of compliance between elements.
3 . Support of sequence of actions.
4 . Possibility of the response to a question, input arbitrary (on a syntax) the text of the response to a question in a special window of input
Use of the adaptive testing methodologies for the purpose of abbreviation of the general time of testing is perspective, however introduction of these techniques is complicated by difficulties of an assessment of complexity of asked questions [1]. Actual problems of the virtual educational system (VES): creation of the reliable tool of distant on-line of testing and assessment of knowledge of users, on-line organization of a database of control questions, organization of means of self-test and self-checking of students and momentary estimation of their knowledge. I will mark some advanced developments provided in the market of the modern specialized software. It is system of remote learning of WebTutor (The Web software company - the developer of difficult information systems and program complexes. http://www.websoft.ru/) the ready decision for creation of system of remote learning and a corporate educational portal. STELLUS (http://www.stel.ru/do/frameabout.htm) - full-function, constructed on web technologies, a modular complex of the software for support of open education. System of the organization and carrying out testing of SunRav TestOfficePro http://www .sunrav.ru/srtop/index.shtml. Despite existence of these known development and several tens not called me less known, development of systems of testing and monitoring of knowledge of pupils remains on former actual. It speaks as rather high cost of the provided development for a customer, and what not all development allow to create highly effective tests of monitoring of knowledge of pupils on some special disciplines. For example, the testing systems oriented on monitoring of knowledge in the field of organic chemistry, shall provide possibility of easy creation of difficult chemical formulas [2].
The software allows to load the information intended for testing then it is possible to break off on-line connection and to execute dough passing in a standalone mode (off-line). After delivery of dough it is possible to send information with the ciphered responses to questions, having directly connected to the server or having executed sending information on e-mail. Developed by the software, registered in OFAP (a code of the program by ESPD.03524577.00658-01, completion date of development 28.04.2004), it is used in educational process. Databases with tests are prepared for courses: "Algorithmic languages and programming", "Programming in languages of the high level", "The theory of information systems", "Systems analysis of chemical technologies", "Operation with STN International network databases".
The program complex of testing is intended for examination in the form of dough. Consists of 3 parts which can be on different computers. Communication between computers can be carried out by means of a local area network (LAN), e-mail or with use of the external information medium.
