IBT APPLICATION

• IBT example using Drupal 6Drupal is a PHP-based Content Management System (CMS). Drupal CMS can also be downloaded and freely developed as it is open source. Drupal has a vast potential development in various fields.

The Drupal usability in general:

• Community Portal Site• News Publishing• Aficionado Sites• Intranet/Corporate Web Sites • Resource Directories• International Sites• Education • Art, Music, Multimedia• Social networking sites

Drupal based IBT offers functionally in which it has various quiz types, multimedia compatibility, god administration and management practically. The outline of IBT application is stated as follows:

Administrator provided IBT, students’ username and password, and polls.

Student visited “hartoyomedia.OOOspace.com” Students logged in to the website using username and

password given. Students did the quiz. Students filled out on-line polls after they have finished doing

the quiz. Students updated students account and chage students

password for security reason. Administrator managed IBT result and polls.

The advantages of Drupal:

The advantages Drupal based IBT application:• Various quiz types,• Scoring flexibility,• Multimedia compatibility,• Systematic data base and administration,• Ease and secure usage,• Stable, secure, and robust performance.

The further development, teacher can install gradebook module as students’ report, learning activities, assignments, etc. drupal also enables administrator (teacher)to manage users’ role whether the user is test taker, teacher, administrator, or others.

The disadvantages of Drupal:A) Development

There are some obstacles to consider in developing drupal:• Internet Connection• Downloading Drupal core and modules need robust internet connection.• Human Resource• This problem emerges because the developer/researcher has limited skill in

developing website as a beginner. However, by realizing the huge benefit researcher needs to hone his skill.

• Time Allocation• In order to get a good website with appealing appearance and functionality

developer needs enough time allocation. Bear in mind that a website is not one shot project, however, a continuous project.

• Hosting• The IBT prototype was hosted to a free hosting “OOOspace.com”. it served well,

however the disk capacity and services was limited. In order to get better service it is suggested to use commercial hosting. By considering this reason, website with the URL “hartoyomedia.OOOspace.com” was upgraded to “hartoyomedia.com”.

B) ApplicationWhile the obstacles found in IBT application were:• Notebook Availability• Not all of the students had notebook, so that some of them had borrow them

from their friend.• Internet Connection• Almost all of students used wireless hot spot services provided by the

department, and only few of them used personal modem. The internet connection was very limited to accommodate test takers as a result the connection was slow.

• Power Outlet• Power outlet availability needs to consider. Many notebooks had to be

recharged before test takers finished doing the test. Unfortunately power outlets were not enough.

• Students Honesty• The major concern in IBT application is students’ honesty, because internet

provides “unlimited” information in almost all fields, students could easily browse to the references they needed. Better system and better attitude is absolutely needed.

Students’ response

Summary

Science and technology development opens wider chances in almost all aspect of life, including education ICT can be utilized not only in teaching and learning, but also in testing. Computer Based Testing (CBT) or Internet Based Testing (IBT) is used wider and wider as a means of assessment. The benefits of IBT and CBT are; flexibility, speed, wide range, and ability to accommodate students with special needs. Meanwhile a number of obstacles in the information of CBT or IBT come from knowledge and mastery about computer, hardware and software, test participants behavior or attitude, and the questions format that really assesses students’ academic ability.
