COLLECTION OF TESTS
for current monitoring of student progress

Designed by:

ANNOTATION
collection test items
The collection of test tasks provides for the implementation of current monitoring of students' progress on topics and sections included in the interdisciplinary course 01.01 Car arrangement in the preparation of mid-level specialists 23.02.03 Maintenance and repair of motor vehicles of a basic level.
The test tasks in the collection are designed in such a way that, first of all, students are tested on the knowledge of the device and the fundamentals of the theory of mechanisms and systems of modern cars produced by domestic and foreign automobile concerns, and then the basic and fundamental concepts.
Test tasks for monitoring current progress - this is a system of tasks special form, which allows to measure the level of knowledge, skills and abilities of students that require short unambiguous answers. In order for the test to be a real tool for measuring the progress of students, it contains a sufficient number of tasks on each topic, while each test task was selected through many years of approbation of students. Test tasks quickly reveal how students perceive the reported information and apply appropriate measures if gaps are found in the understanding of the material covered. Tasks are used both in the frontal control of students, and in additional classes, consultations, in the process of performing homework students, as well as in preparation for tests and exams.
The test tasks of the collection are compiled in accordance with the classification of the Russian testologist, Doctor of Pedagogical Sciences Avanesov Vadim Sergeevich. The collection has four forms of test tasks:
1. Test tasks of the closed form are tasks with the choice of one or more correct answers.
2. Test questions of the open form offer an open answer. They are formulated as statements that turn into a true statement if the answer is correct and false if the answer is wrong.
3. Test tasks for establishing correspondence are tasks in which it is necessary to establish a correspondence between the elements of one column and the elements of another column. These tasks reveal associative knowledge. This knowledge is about the relationship between definitions and facts, forms and content, essence and phenomena, about the relationship between various objects, properties, laws, formulas.
4. Tasks to establish the correct sequence to test knowledge, skills and abilities to establish the correct sequence of various terms, definitions.
The collection of test tasks covers the control of such topics of Vehicle Devices as “Design, basic parameters and engine operating cycles internal combustion»; "Crank mechanism"; "Gas distribution mechanism"; "Engine cooling system"; "Car engine lubrication system"; " Automotive fuel and types of combustible mixture”; "Gasoline engine power supply system"; "Electronic control system of a gasoline engine"; "Diesel engine power supply system"; "Clutch of the car"; "Transmission"; "Accumulator battery"; "Generator"; "Car ignition system"; " Car tires»; "Steering"; "Brake systems". It also provides for monitoring progress in the entire section "Engine".
The collection is used by the teacher both to check the current performance of full-time students, and successfully acts as a tool for checking the level of knowledge, skills and abilities of part-time students, who, unlike full-time students, have extensive practical experience behind them.
The most important thing in the collection of test tasks, as is usually the case, is that there is no key to the tests, that is, teachers and students can build the answer themselves and at the same time check their knowledge and find the answer not from the key, but from the primary source (textbook, reference book, Internet, magazine, manual for vehicle operation).
The collection of test tasks can be used in the educational process of the technical school in the preparation of skilled workers by profession 23.01.03 Auto mechanic. Compliance of test tasks with the requirements for the learning outcomes of the training program for mid-level specialists in the specialty allows the collection to be used in the educational process of other professional organizations involved in the preparation of graduates in the enlarged group of specialties "Engineering and technology of land transport".
