To complete the tasks in the “Listening” section, technical specialists or organizers set up an audio playback facility so that all students can hear it. Students listen to the audio recording twice, after which they begin to perform ER.
OGE in foreign languages (section “Speaking”).
Order-9 does not provide for students’ refusal to participate in the OGE in a foreign language (section “Speaking”).
Passing the OGE in a foreign language requires the mandatory participation of students in completing written tasks, as well as tasks in the “Speaking” section.
When conducting the OGE in a foreign language (section “Speaking”), oral answers (hereinafter referred to as ER) to tasks are recorded on audio media.
Conducting the OGE in a foreign language (section “Speaking”) includes completing 3 tasks:
– reading aloud a short text (preparation time – 1.5 minutes, task completion time – 2 minutes);
– participation in a conditional questioning dialogue (dialogue questions are recorded on audio media, the response time to each question is no more than 40 seconds);
- monologue statement in a specific topic based on the plan (preparation time - 1.5 minutes, task completion time - 2 minutes).
The lead time is 15 minutes per responder. Each subsequent task is executed after the completion of the previous task. The entire response time is audio recorded.
The use of drafts by participants in the OGE in a foreign language (section “Speaking”) is prohibited by Order-9.
Two types of classrooms are used to conduct the oral part of the exams:
– a training room, in which participants wait their turn to take the exam, fill out the BO-1 registration fields, no additional equipment is required for training rooms;
– the auditorium in which the participants are briefed, CMMs are issued, the participants enter the CMM number into the appropriate field BO-1, means of audio recording and playback of audio recordings must be prepared in the auditorium.
Technical specialists or organizers in the audience set up digital audio recording tools to ensure high-quality recording of the OU.
In the preparation and conducting classrooms there must be at least 2 organizers in each classroom. On the day of the UC exam, a technical specialist must be present at the PPE.
No more than 25 students can be present in the training room at the same time (seating of two people per desk is allowed).
The responsible organizer in the preparation audience and the responsible organizer in the conducting audience receive examination forms at the PPE headquarters for the exam participants and IR with CMM, respectively.
Examination forms are issued to the first group of participants in the preparation room no earlier than 10:00 on the day of the exam.
When an exam participant fills out the BO-1 registration fields in the preparation room, the room number and the CMM number are not indicated.
Students are invited to the classroom to receive the CMM assignment and subsequently record oral responses to the CMM assignment.
Exam participants are escorted from the preparation classroom to the conducting classroom by the organizer outside the classroom.
Each group of participants enters the classroom only after all participants from the previous group have completed the exam (it is recommended that after one workplace a maximum of 4 OGE participants were able to pass in the auditorium per day).
In the audience, the participant takes a workplace.
The organizer in this audience gives instructions:
– about filling out the fields for the audience number of the event and the CMM number;
– about the time to prepare and complete tasks.
The organizer also warns the participant that when performing task 2 (conditional dialogue-questioning), it is necessary to answer the question immediately after listening to it, then listen to the next question and answer. The participant should be informed that there is no time to prepare for answering the questions in task 2. Before starting to answer questions, the participant speaks the unique identification number of his work into the audio recording device.
Before answering each task, the participant pronounces the number of each task in RY.
After completing the 1st task, the organizer must play the audio recording of the 2nd task (conditional dialogue-questioning).
The participant listens sequentially and answers each question in the audio recording, and then proceeds to prepare and complete the 3rd task.
After 15 minutes, the organizers in the audience announce the end of the exam and turn off the audio recording of the answer.
The organizers (technical specialist) saves an audio recording of the participant’s response under a certain code – PPE number_audience number_unique identification number of the work .
The participant signs the exam sheet.
After all participants in the group in the conducting audience have completed the work, a person from the waiting audience is invited to the conducting audience. a new group participants.
Organizers monitor the preparation time for tasks and control the time for completing tasks. If the time to prepare for a task or the time to respond to a task has expired, the organizer must inform the participant about this. The technical specialist or organizer allows the student to listen to the recording of his answer and make sure that it was produced without technical failures. If a technical failure occurs during recording, the student is given the right to take the “Speaking” section again.
If there is a technical failure of the equipment or a low quality audio recording of a participant’s answer in the OGE in a foreign language is detected after he has completed the tasks in the “Speaking” section, retaking the UC exam is possible on the same day or at additional times established by the schedule.
Upon completion of the exam by all participants, audio recordings with answers are collected by a technical specialist into class-by-class catalogs and sent to the RCIO for examination of the answers on removable electronic media.
OGE in physics
The OGE in physics includes an experimental task performed on real equipment.
Scroll additional materials and equipment, the use of which is permitted for the OGE in physics, is approved by order of the Ministry of Education and Science. A non-programmable calculator (hereinafter referred to as NPC) is used for each student and experimental equipment.
The exam is held in physics classrooms. If necessary, you can use other rooms that meet the requirements for safe work when performing experimental ER tasks. A physics specialist is present at the exam, who gives safety instructions before the exam and monitors compliance with safe labor rules while students are working with laboratory equipment.
Laboratory equipment kits for performing laboratory work are formed in advance, before the exam. To prepare laboratory equipment, the PPE is informed one or two days before the exam of the numbers of equipment sets that will be used in the exam. The list of equipment sets for performing experimental tasks is compiled on the basis of standard sets for frontal work in physics, as well as on the basis of “GIA-laboratory” sets.
If there are no devices and materials in the PPE, the equipment can be replaced with similar ones with different characteristics. In order to ensure an objective assessment of the performance of laboratory work by OGE participants, in the event of replacement of equipment with a similar one with other characteristics, it is necessary to bring to the attention of PC experts who check the completion of tasks a description of the characteristics of the equipment actually used in the exam.
The head of the PPE/member of the State Examination Committee draws up an act on the replacement of equipment in free form, and the act is transferred along with the EM to the RCIO.
Tasks with RO are assessed by two experts taking into account the correctness and completeness of the answer.
OGE in literature
When completing tasks in both parts of the ER, the examinee has the right to use the full texts of literary works, as well as collections of lyrics.
Literary texts are not provided individually to each examinee. Examinees, as necessary, work with texts at separate tables on which the necessary books are located. When conducting an exam, it is necessary to prepare books in several copies for each audience (depending on the content). Books should be prepared in such a way that the examinee does not have the opportunity to work with commentaries and introductory articles to literary texts. The examiner must provide equal conditions of access to literary texts for all exam participants.
