Опрацювання та інтерпретація результатів тестування засобами електронних таблиць Microsoft Excel

Abstract

У статті розкрито зміст поняття «система завдань у тестовій формі»; коротко схарактеризовано чотири види систем завдань у тестовій формі (ланцюгова, тематична, текстова, ситуаційна); наведено приклад авторської ланцюгової системи завдань у тестовій формі. На основі авторської ланцюгової системи завдань у тестовій формі покроково описано процедуру опрацювання та інтерпретації результатів тестування засобами електронних таблиць Microsoft Excel.

The article reveals the concept of the «tasks system in test form» where is shown the difference of the tasks system in test form from the test. Thus, unlike the tests, in the system of tasks the probability of correct answers on the next test may depend on the probability of a correct answer on the previous test. The short description of four types of tasks in the test form is given (chain, thematic, text, situational). As an example the author’s chain of tasks in the test form is provided. Based on the author’s chain of tasks in the test form the procedures of testing results processing by means of spreadsheet Microsoft Excel, which includes 6 steps are described: - Step 1. Forming the test results matrix. - Step 2. The transformation of the test results matrix. - Step 3. Calculation of the individual scores of the tested persons as well the number of correct answers to each task of the test. - Step 4. The regulation of the matrix results. - Step 5. Graphical representation of the dates. - Step 6. Defining the characteristics of the sample results. Each step does not only present a procedure of the results processing but also the interpretation of the results. In particular, the indicators of the value of the author’s chain of tasks in the test form are calculated and which revealed that this system is a quite complicated task for students. However, this difficulty lies more in the specifics of this task as there are dependence of chain exists: the correct answer for one task depends on the correct answers to the previous ones. To improve the quality of the author’s chain of tasks in the test form one can through the addition of lighter tasks. The article shows that the processing and interpretation of test results makes it possible to assay of the test on its quality, particularly what concerns its complexity and to see the shortcomings of the test created which, in turn, would allow to improve this test.
