Answers and criteria for assessing the completion of tasks in part 2 118

The examination paper consists of two parts, including 20 tasks. Part 1 contains 18 short answer tasks, part 2 contains 2 tasks that must be completed on the computer.
2 hours 30 minutes (150 minutes) are allotted to complete the examination work in computer science. You can proceed to completing the tasks of Part 2 only after passing the completed tasks of Part 1 of the examination paper. You can independently determine the time you allocate for completing the tasks of part 1, but the recommended time is 1 hour 15 minutes (75 minutes) and for completing the tasks of part 2 also 1 hour 15 minutes (75 minutes).
When completing tasks in Part 1, you cannot use a computer, calculator, or reference books.
Answers to tasks 1-6 are written as one number, which corresponds to the number of the correct answer. Write this figure in the answer field in the text of the work, and then transfer it to answer form No. 1.
Answers to tasks 7-18 are written as a number, a sequence of letters or numbers. Write the answer in the answer field in the text of the work, and then transfer it to answer form No. 1. If the task requires you to write down a sequence of numbers or letters as an answer, when transferring the answer to the form, you should indicate only this sequence, without spaces, commas and other additional characters .
Part 2 contains 2 tasks (19, 20). The result of each of these tasks is a separate file. The exam organizers will inform you of the file format, its name and the directory for saving.
When completing assignments, you can use a draft. Entries in the draft are not taken into account when grading work.
The points you receive for completed tasks are summed up. Try to complete as many tasks as possible and score the most points.

Specification
control measuring materials
to be held in 2017
main state exam
in COMPUTER SCIENCE and ICT

1. Purpose of CMM for OGE– to assess the level of general educational training in computer science and ICT of IX grade graduates of general education organizations for the purpose of state final certification of graduates. The exam results can be used when admitting students to specialized classes in secondary schools.

OGE is carried out in accordance with Federal law Russian Federation dated December 29, 2012 No. 273-FZ “On education in the Russian Federation.”

2. Documents defining the content of CMM

3. Approaches to content selection and CMM structure development

The examination paper covers the main content of the computer science and ICT course. The most significant material is covered, which is clearly interpreted in the majority of computer science and ICT course options taught at school and is included in the Federal component of the state educational standard for basic general education.

The content of the assignments is developed on the main topics of the computer science and ICT course, combined into the following thematic blocks: “Representation and transmission of information” (sections 1.1 and 1.2 of the codifier), “Information processing” (sections 1.3 and 1.4 of the codifier), “Basic ICT devices” (section 2.1 of the codifier), “Recording information about objects and processes by means of ICT, creation and processing of information objects” (sections 2.2 and 2.3 of the codifier), “Design and modeling” (section 2.5 of the codifier), “Mathematical tools, spreadsheets” (section 2.6 codifier), “Organization of the information environment, information search” (sections 2.7 and 2.4 of the codifier).

The work does not include tasks that require simple reproduction of knowledge of terms, concepts, quantities, rules. When performing any of the tasks, the examinee is required to solve a problem: either directly use a known rule, algorithm, skill; or choose the most suitable one from the total number of studied concepts and algorithms and apply it in a known or new situation.

Part 2 of the work contains practical tasks, testing the most important practical skills of the computer science and ICT course: the ability to process a large information array of data and the ability to develop and write a simple algorithm.

Examination tasks do not require students to have specific knowledge operating systems And software products, skills to work with them. The elements being tested are the basic principles of presentation, storage and processing of information, skills in working with such categories software, as an electronic (dynamic) table and a formal executor’s environment, rather than knowledge of the features of specific software products.

The practical part of the work can be performed using various operating systems and various application software products.

4. Connection of the OGE exam model with the Unified State Exam KIM

A significant part of tasks with a short answer are similar in type Unified State Exam assignments in computer science and ICT, but in content and complexity they correspond to the level of basic general education. At the same time, the work includes tasks from some sections of the computer science course that are not included in the Unified State Exam in computer science and ICT (for example, tasks related to the technology of processing large amounts of data in spreadsheets).

One of the differences in the structure of the OGE KIM is the format of part 2 of the work (tasks with a detailed answer). Unlike the Unified State Exam, where Part 2 is performed on a form and the result of the work is a written solution, checked by an expert, in the Unified State Exam Part 2 is performed on a computer and the checked result of the task is a file. This allows you to significantly expand the possible topics of assignments and the variety of skills being tested, as well as in the future move to an exclusively computer-based form of passing the exam.

5. Characteristics of the structure and content of CMM

The examination paper consists of two parts.

Part 1 contains 18 tasks basic and advanced levels of difficulty, including 6 tasks with the choice and recording of an answer in the form of a single number and 12 tasks that require the examinee to independently formulate and record the answer in the form of a sequence of symbols.

Part 2 contains 2 tasks high level difficulties. The tasks in this part involve practical work students at the computer using special software. The result of each task execution is a separate file. Task 20 is given in two versions: 20.1 and 20.2; The examinee must choose one of the options for the task.

Training version of the OGE 2017 in computer science, option 1 with answers, compiled according to the sample demo version 2017.

The work consists of two parts, including 20 tasks. Part 1 contains 18 short answer tasks, part 2 contains 2 tasks that must be completed on the computer.

IN this section you will find online tests that will help you prepare to take the OGE (GIA) in computer science. We wish you success!

The standard OGE test (GIA-9) of the 2019 format in computer science and ICT contains two parts. The first part contains 18 tasks with a short answer, the second part contains 2 tasks that must be completed on the computer. In this regard, in this test Only the first part (the first 18 tasks) is presented. According to the current exam structure, among these 18 questions, only the first 6 questions offer answer options. However, for the convenience of passing tests, the site administration decided to offer answer options for each task. However, for tasks in which the compilers of real test and measurement materials (CMMs) do not provide answer options, we decided to significantly increase the number of these answer options in order to bring our test as close as possible to what you will have to face at the end of the school year.
