Lecture 4. Development and development of the contextual structure of information from common information resources based on search engines
The purpose of the lesson: Studying the development and development of the contextual structure of information from common information resources based on search engines of organizations
Plan:
1. Common Information Resources
2. Technologies and search of thematic catalogs
Information on the organization of the search and selected learning from the Internet, the model of information resources is based on the accumulated and specific didactic and methodological capabilities in the global environment. Special technologies have great potential that can change traditional systems and the search for an educational process. They create additional didactic conditions for increasing the push of the applicant's case, changing the attitude to the learning process in order to form students' abilities for self-knowledge and development. A feature of these technologies is the choice of the huge possibilities of the student and the receipt of information in various directions.
Search technologies are implemented in various information and reference systems that will help a person find the necessary information. Examples include subject directories and search engine functions.
Subject catalogs are information and reference systems prepared by editors in these systems based on information collected on the Internet. To jump to a section in the thematic catalog, you can use automatic search using quick keywords. Thematic examples of directories:
* Catalog of children's resources of the Russian Internet (via HTTP / / VSP. kinder.rov);
* Federal portal "Russian education" (via HTTP// VSP. portal. Edu.rov);
* Student's world: directory of educational resources (via http / / wsp. school.holm. moat)
* Ministry of Education and Science of the Republic of Kazakhstan (as agreed) www. edu. gov. kz/ru)
* Catalog of educational resources for students www. pushkinlibrary. kz
The system provides information support for systems based on complex information and reference data systems, including network robot programs and the search for automatic systems on the Internet, as well as links to various resources that answer questions asked by people. An example to them: • In Google (via HTTP//VSP.Google.KZ);
• (via HTTP//VSP.Rambler.com);
• (via HTTP//VSP.Yandex.ru).
Using the capabilities of search technologies and systems, a computer science teacher can prepare a report, an abstract for students and offer a search and comparison of issues related to particular education. But it is important that students can work with information resources in research activities (find the necessary information, use it for analysis and study). Information search is one of the stages of research activity and the process of searching for structured documentary information in a widespread information environment. In this case, it determines from among a certain set of documents one document on a given topic that satisfies predefined search conditions or contains citations, information, and information.
The search process consists of homogeneous operations designed to collect, process, and present the necessary information. Typically, the search for information consists of four stages:
1. General Provisions Defining the need for information and creating an information request.
2. Determining the source of information.
3. Selection of information from certain information arrays.
4. Familiarization with the received information and evaluation of the results.
To properly organize the search for information, you need to know that Internet resources consist of a website, a web portal and web rings.
A website or site is a set of web pages related to a single topic that can be accessed over the Internet. All open web pages make up the World Wide Web (WWW). A web page is a hypertext resource on the World Wide Web. On the Web page, along with texts, links are placed for quick access to videos and other pages. It can contain media files, such as sound files and video files (video), applets, as well as scripts that dynamically render page content.
To organize the educational and cognitive activities of students, the teacher can actively use websites on the Internet. For example, a teacher may invite students to use an electronic library.
An electronic library is a website designed to collect various texts (mainly literary, but also other topics and even computer programs) that the reader may need at any time. The format common in the electronic library of works can be divided into two categories: the format for reading online text and the format for writing to the reader's computer.
Free Computers Book from the electronic library HTTP: //www. freecomputerbook.com and programming and computer (http: //books.kulichki.net. ) can be allocated a book fund.
The library consists of textbooks on computer science, programming (Delphi, C, C++), operating systems (Unix, FreeBSD, Linux, Netware), databases (SQL, Access), computer hardware, networks and software (Photoshop, Flash MX). They can be both read and written. In addition, various issues can be discussed on the site's forum or in the chat.
A great opportunity will be the use of Internet resources, such as a virtual tour to conduct research with participants.
A virtual museum (museum website) is the optimal type of website for displaying museum materials. The reviewed materials can be located in different areas, including from historical artifacts and art media to historical exhibits and a virtual collection. The virtual museum is a successful example of the use of Internet technologies to solve the problems of exhibit storage.
In 1991, the first museum websites appeared on the Internet. At first, there was a site for a genuine museum, and then virtual museums began to appear. The first virtual museum was opened in 1994. Any set of documents and photographs cannot be a website museum.
The digital collections of a virtual museum must adhere to two specific characteristics: virtual travel and search engines.
There are a large number of museums on the Internet - electronic presentations of virtual museums and genuine museums. For example: in the virtual computer era in the museum of the history of the illuminated calculation before the computer, the history of the development of computer technology abroad and in ours, the history of electrical communications http://computer-museum. ru in the document, assembled.
For search works and media lessons of participants, you can use the online edition. This is a media outlet that distributes its products via the Internet. As a rule, traditional print and broadcast media have their own websites. They are sometimes completely repeated in their content, sometimes they are only announcements of articles or texts of past numbers. For example: in the edition of the website "Open System" you can find new numbers of magazines "Computerwold", " Networks”, “LAN”, “Windows IT Pro”, “PC World”. There are Internet publications that are not published in tape form, not broadcast, published only on their website.
A Web portal site is another type of information resource organization. It allows the Internet user to obtain further information from other sites, in other words, it forms many internal links. According to the rules, portals provide the user with a list of additional options in accordance with the structure and elegance of the information that suits his interest.
The portal "information and communication technologies in education" http://www.ict.edu.ru) is part of the system of federal educational portals. It is aimed at providing comprehensive information support for education in the field of modern information and telecommunication technologies. Links to this portal are given in e-library, a series of books, a package of Internet resources, conference materials. The portal has a search engine that allows you to organize the necessary materials according to various parameters.
Another way to organize Internet resources is a webring that brings together similar topics of websites. Therefore, each site of a member with such a ring places links on its web pages that go to the next and previous member of the ring. By clicking on the links, you can view the sites of all members of the ring. Webrings are search engines and directories and ways to unify sites on the Internet.
The information activity of students, aimed at the search and productivity of various types of information, can be actively used in the combination of media and educational management in teaching computer science.
Media education is associated with the development of students' creative abilities, as well as with the possibilities for realizing the child's personal creativity in the environment of communications and the media. In teaching computer science, there are a lot of varieties of media educational programs. This is the creation of a media text, a virtual tour, exhibitions, etc. b.
The work carried out is analyzed by teachers and other students, from which possible errors are identified. Then these works are refined and modified.
