ANNOTATION
Collection of test tasks
A collection of test tasks provides for the implementation of current monitoring of student performance on topics and sections included in the interdisciplinary course 01.01 A car device during the preparation of middle-level specialists 02/23/03 Maintenance and repair of baseline road transport.
Test assignments in the collection are designed in such a way that, first of all, students are checked for knowledge of the device and the foundations of the theory of mechanisms and systems of modern cars produced by domestic and foreign car concerns, and then basic and fundamental concepts.
Test tasks of control of current performance is a system of tasks of a special form, allowing to measure the level of knowledge, skills and skills of students that require short unambiguous answers. In order for the test to be a real tool for measuring learning performance, it contains a sufficient number of tasks on each topic, while each test task was taken by many years of tested learning. Test jobs are promptly detected, as perceived by the student reported information and appropriate measures are applied if the gaps in the understanding of the material passed are detected. Tasks are used both when conducting frontal control of students, and at additional occupations, consultations, in the process of performing homework students, as well as in preparation for credit and exams.
Test assignments of the collection are compiled in accordance with the classification of the Russian testologist, Dr. Pedagogical Sciences Avanesov Vadim Sergeevich. The collection has four forms of test tasks:
1. The test tasks of the closed form are tasks with a choice of one or more correct response options.
2. Open-shaped test tasks offer open response. Formulate in the form of statements that turn into a true statement if the answer is correct and in false, if the answer is incorrect.
3. The test tasks for conformity establishment represent the tasks in which it is necessary to establish the correspondence of the elements of one column to the elements of another column. These tasks detect associative knowledge. These knowledge of the relationship of definitions and facts, forms and content, entities and phenomena, the ratio between various objects, properties, laws, formulas.
4. Jobs on establishing the correct sequence Check knowledge, skills and skills to establish the correct sequence of various terms, definitions.
Collection of test tasks covers the control of such topics of automobiles, such as "device, basic parameters and internal combustion engine operating cycles"; "Crank mechanism"; "Gas distribution mechanism"; "Engine cooling system"; "Car engine lubrication system"; "Automotive fuel and types of combustible mixture"; "Power supply system of a gasoline engine"; "Electronic gasoline control system"; "Diesel engine power system"; "Coupling of the car"; "Transmission"; "Accumulator battery"; "Generator"; "Car Ignition System"; "Car tires"; "Steering"; "Brake systems". Also prolonged performance on the whole section "Engine".
The collection is used by the teacher, both to verify the current performance of students in full-time, and successfully performs a tool for verifying the level of knowledge, skills and skills, studying absentee branches, which, unlike students, have a large practical experience.
The most important thing in the collection of test tasks as it usually happens, there is no key to tests, that is, teachers and students can build the answer themselves and at the same time will check their knowledge and will find the answer not from the key, but from the original source (textbook, directory, Internet, magazine, leadership Operating a car).
A collection of test tasks can be used in the educational process of a technical school when preparing qualified workers by profession on January 23, 2003. Auto mechanic. The compliance of test tasks with the requirements for the results of training programs for the training of middle-level specialists in the specialty allows us to apply the collection in the educational process of other professional organizations involved in the preparation of graduates at the integrined group of specialties "Technique and Ground Transport Technology".

TEST
When performing test work, you need to solve three tasks and respond to five questions from the list below. Tasks and questions are divided into 20 options: 10 even 10 odd. The choice of option is carried out in two latest student cipher numbers. If the penultimate digit is even, then the option is taken from the onely group, and if something is odd, then the option is taken from the odd group. The last digit of the cipher corresponds to the option number.
Question numbers are given in Table 1. Answering the question, you first need to write down his text, and then state the answer content in your own words, if possible, briefly, but quite exhaustive.
