DESIGN OF KNOWLEDGE TEST

Testing is used to assess the level of knowledge in schools, in employment, to assess the qualifications of personnel agencies. In other words almost all spheres of human activity. The subject is asked a series of questions that he must answer.

Typically, each question is given several answers from which you must select the correct. Each option corresponds to a specific response assessment. Summing the ratings for the answers obtained a total score. Based on the total score is concluded that the level of preparedness of the student's.

Objective of the study is to develop students' knowledge control module. In this module should be laid ability to adapt to the characteristics of the examinee.

As a programming language for the development of knowledge control module was chosen object-oriented programming language Borland Delphi 7. Because this language contains all the necessary conditions for the realization of our objectives:

1) Building applications visually of software prototypes.

2) Scalable to build databases - Support for all popular database formats.

3) Support for client-server technology. Compiler, built in Borland Delphi 7, provides high performance.

In the target module, the control of knowledge, testing is carried out by means of bank jobs. Tasks are divided by level of difficulty. First asked the average complexity, and the answer affects the future assessment. Then selected and given a more difficult question.

If the answer is given incorrectly, the student's score is reduced. As the next question again offered an easier question. As defined more and more questions, more accurate is the assessment of the student's level of knowledge. The test ends in two cases: when the accuracy of the estimate reaches a statistically acceptable level or when it is set to the maximum number of questions.

The structure of the software module is generated during the design of the program module. The program control module consists of knowledge modules and files. They are presented in tables 1 and 2.

Table 1 – List of modules

Module	The original file and the shape	Assignment
Unit1	Test1.pas, AdaptivTest	The shell that loads of adaptive test file Test.doc
Unit2	Test2.pas, Registration	An application in which the user logs into the system

Table – List of files

File	The original file and the shape	Assignment
Doc1	Reg.doc	The file that stores the results of registration and the scores after the test
Doc2	Test.doc	Bank of test items, divided into levels of difficulty

From the main form before undergoing the test is access to the module registration. The data transmission between the modules and files may be represented as follows.

Figure 1 – Data transmission between the modules and files

In the main module implements procedures and functions. They are responsible for performing basic actions:

1) processing of the raw data;

2) function of student registration;

3) link to the file bank of test items;

4) link to the file registration of students;

5) conclusion of questions and answers on the screen;

6) calculation of test results;

7) saving outcomes;

8) output from the program.

The developed module control knowledge can be used to create a variety of electronic systems used separately or as a standalone program for testing students' knowledge.
