Computer Based Test/Examination (CBT) Using Linear Congruencial Method To Generate Questions

Taking advantage of computer technology in education will help the semester exams in every school become simpler during the process of the exam and scoring, School use manual exam system. They have to print out test paper, undisciplined students can cheat during exam, mistakes during marking the test, and unorganized archives when filing the student’s results. To solving their current problems designed a new system will organize the information electronically in filling the student’s grades and making a random order of questions using Linear Congruential Generator (LCG) method. This computerized system will help the teachers prepare the questions and answer, teacher only have three days to input in database. Marking the answers and filling the grade are automatically by system. With using LCG method, every student will get randomized questions based on Student’s ID Number, this will reduce the possibility of cheating and the students will not be able to continue filling their answers after the time is over. After implementation the system, it gives a benefit to prepare for the exam from 8 days to 1 day. The system test results is 64% can be accepted by the user.

1.1                                 BACKGROUND OF THE STUDY

The rapid growth of era and also the information technology advances in Indonesia that are needed and used for daily needs have become common thing for humans. As sharing data for business, education and health needs as well as integrated data storage. Furthermore, by being connected to a computer network that is a system consisting of computers and network devices, that work together to achieve the same purpose so the computers can connect to each other and share data in one of the same server network [1]. Education is a process that takes place in life as an effort to balance conditions in oneself with external conditions. This balancing process is a form of survival that is carried out, so that oneself can follow every activity that takes place in life [2]. Developing technology can be implemented into the education sector, so school data can be integrated and minimize human error. The activity of teachers and school staff is faster in accessing and changing some school data as needed. Education has three main benefits:

(a) for students as self-improvement, increased opportunities for employment, increased opportunities for entrepreneurship, increased income, preparation of further education, self-preparation for society, nation, state, adaptation to change and environment;

(b) for the world of industry can obtain high-quality workforce, ease the cost of business, help advance and develop the business;

(c) for the society can improve people’s welfare, increase national productivity, increase state income, and reduce unemployment. Seeing the benefits of advances in information technology so many educational institutions began to develop their systems, so that the system became integrated using network servers. As well as in the implementation of the National Examination conducted by computer-based by several schools.

With the development of information technology, Schools can improve their educational system. With this system schools longer needs to prepare for semester exam equipment, students become time discipline, students cannot cheat, teachers doesn’t need to correct answers by manually because the value directly in database and stores student value data become organized and easily accessed by teachers who need it. To prevent students from cheating during the semester examination, the system formed uses the Linear Congruent Generator (LCG) as a method of randomizing semester exam questions and report card features that can process student academic grades such as: assignments and semester exams to be final grades so they can be used by homerooms to ease the printing of student report cards.

1.2                                        PROBLEM STATEMENT

Psychological tests are used to determine human’s attitude and behavior. In its application, psychological tests still use the old method. Objects are asked to answer questions and then the answers will be collected again to be calculated, and then conclusion will be drawn from the result. It will be time consuming and impractical. Computer-based psychological test have an answer to these deficiencies. By utilizing the ease of test item management in computer, this paper discusses the application of linear congruential method for randomization of test item in computer-based psychological edwards personal preference schedule (EPPS) test developed by web-based programming.

1.3                                            AIM OF THE STUDY

The aim is to reduce the certainty of answers in an examination especially in term of test item randomization

1.4                                  APPLICATION OF THE STUDY

The application of technology to psychological tests can be in the form of computer- based testing, test item management, and ease of scoring. Management of test item on computer-based psychological tests can be applied with randomization of questions. Changes in the item of the test should be able to keep people’s motivation high.

1.5                                    ADVANTAGES OF PROJECT

Carrying out psychological tests with information technology has a potential to be a practical, cost-effective, and meaningful tool for measuring individuals personality.
