Preparing for testing
When testing, there should be no unforeseen circumstances that reduce the reliability of test results. Therefore, during the preparation phase, the conditions that ensure the uniformity of the testing procedure, as well as those in which the tests are performed, should be standardized as much as possible. It is important to think about how to put together test materials for distribution to students, prepare special spare materials: answer forms, pens or pencils, etc., so as not to distract students from working on the test.
Prior to testing, it is advisable to conduct a rehearsal session, familiarizing students with the assignment forms and the steps to fill out the answer forms, especially if students have never completed tests before.
Requirements for forms for answers to test items. The form should be designed in such a way as to make it as understandable as possible for the subjects and to minimize the time spent looking for a place for answers. In tasks with a choice of answer, the symbol must be offered, p. which marks the correct answer. It is also necessary to identify possible corrections that students have the right to make on the form if the answer changes.
If the registration form is not attached separately, a space should be left at the beginning of the answer sheet for student data.
Conditions under which testing should be carried out. The preliminary preparation for testing concerns not only the materials used, but also the environment. It is necessary to select a room for testing in advance. It should be quiet enough, with good lighting, ventilation and comfortable working areas. When testing large groups of students, the room should provide examiners with free access to the students' seating, provide for the possibility of single-seater boarding of the test subjects and exclude situations that are convenient for cheating when the same version of the test is found in front or on the side of a student sitting on the side.
If testing is carried out in specialized auditoriums (classes of mathematics, physics, etc.), then it is necessary to remove (close) stands, posters and other materials with reference information on the relevant disciplines. Lists of students in the testing room and warning signs prohibiting entry into the premises under any circumstance other than an emergency are usually posted on the door. Assistants must be placed at the doors of the premises to stop access to the room for late students after the start of the tests.
Testing Instructions and Procedure
In the instructions before testing, which can be carried out 2-3 days or on the eve of the test, the teacher must:
1) explain to students why the test is needed, inform how its results will be used;
2) explain why the subjects should make maximum efforts to complete the test, focus the subjects' attention on the possibility of testing their strengths and emphasize the competitive motive;
4) give the subjects the opportunity to practice, to independently solve one or more sample problems. Check if the instruction is understood correctly by analyzing the results of the example assignments right at the consultation;
5) inform about the temporary resource of the test, about the rules for correcting mistakes made, tell about who to contact in case of questions, explain which questions should not wait for answers.
Instructions for students
The test consists of 10 questions. It takes 15 minutes to complete it. Read all assignments carefully before proceeding. Enter your FI data, group number in the answer form. It is recommended to complete the tasks in order. If the task cannot be completed immediately, go to the next one. If time remains, return to missed assignments. Mark the correct answers on the answer sheet.
