While creating of educational system of modeling of microprocessor systems (MPS) it is natural to aspire to an openness, i.e. opportunity to expand a palette of models of microprocessor device (MPD), which here and below are meant as microprocessors, microcontrollers, interface and other modules of expansion of MPS. The openness enables to attract a wide circle of the experts in updating the set of MPD models and creates conditions for use the model creation process as a kind of educational activity of the students.
For maintenance of an openness the educational system of modeling should have rather advanced repository of objects. The activity, which should be supported by such a repository, includes the following kinds of works:
Selection from repository of ready model of MPS structure as the prototype and inclusion of the MPS model in repository with an opportunity to establish the access rights to it;
Updating of model of MPS structure by addition or replacement of its components by selectiong them from repository;
Inclusion of MPD models in repository;
Inclusion of models of MPS parts or subsets of MSP operations in repository. The work at a parts models' level allows to share the development of complex MPS model between many students and to organize the development process as a consecutive increase of a subset of components;
Testing of MPD models with an opportunity to separate the personal tests of the student developing models from the control tests of the teacher;
Study of structure both functioning MPD and design decisions MPS. Thus the special descriptions MPD, tests of knowledge, models functioning as in a mode of demonstration, and in a mode of dialogue with the student are used.
Development of the programs for MP with use given repository of means of development (assemblers, debuggers) and opportunity of inclusion of program modules in repository with the purpose of use in the various projects.
Development of models of behaviour of external environment(objects of the control and management MPS) and their inclusion in repository.
Administration of databases repository with an opportunity to operate access to its components.
Thus, objects of the repository are: models of structures MPS, model MPD, model of parts and subsets of operations MPD, tests of models, description MPD and MPS, training scripts of demonstration of behaviour of models, tests of knowledge of the students, means of development, program for MP, script of behaviour of external environment, data about the users of repository components and their rights.
Repository works over a storehouse of objects, and structurally represents a composition including the manager, data for access control, description of objects. The manager supports operations of insert, removal, updating of the descriptions of repository objects and management of access to them with the purpose of updating and use in the projects, formation of the lists of objects for support of dialogue process of a choice by the user, dispatch of the messages about updating objects to the interested users. Thus the objects can be united in the lists to the following attributes:
The objects concerning a certain type MPD; such association provides support of study certain MPD, at which in process can be included all accessible data, model and script; besides such linkage enables to create the repository versions, specialized on various types MPD;
Objects concerning one project MPS;
Objects concerning group of the projects, realized within the framework of determined theme;
Objects concerning work of the student;
The objects developed by the certain author;
Objects forming environment of development of the project MPS;
The objects modified in a certain interval of time;
The objects described by a certain degree of intensity of use.
To support the described usage of the repository, its objects first of all should gain such properties: the name, purpose, version, date of last updating, owner, rights of access, classification attributes (theme of an educational course, name of the project, to which concerns object and etc.), reference to the information description MPD, characteristics of intensity of use of the object.
R.N.Sattarov PECULIARITIES OF THE ECOLOGICAL TRAINING ON THE BASE OF A MULTIMEDIA ENCYCLOPEDIA
The educational institutions have a need in the constantly renewed stream of scientific- technical, marketing-related, financial, legal, political, ecological and cultural information. All this kind of information is intercommunicated in one or another extent.
The perspective informational policy of educational institution must provide a student maximum information, means for its collection, its processing and usage. For this purpose a structure of the informational provision of the learning ecological multimedia- encyclopedia was worked out. The given approach reflects a methodology of the modern scientific research, that is exactly - orientation to the integral sight of the studied object (discipline), consideration of the complicated intercommunications of the whole and the separate.
The process of a man-computer intercommunication pursues the following objectives: development of the independent thinking, scientific intuition, creative search, etc. The learning multimedia-encyclopedia has two scenarios:
Scientific- literary scenario.
Scenario of inquiry
This scenario provides a transition from information to its higher form - knowledges. The developed structure gives the opportunity to carry out analysis of the educational material consciousnessly, with the help of the main points and of the sense structure's links. By this the preliminary algorithmization of the educational material is achieved. The access to Internet is envisaged. During the process of education a student cultivates an ability to explain a modern condition of the discipline in a short and systematic way.
