Abstract
Abstract Despite the growing popularity of network operating system courses in vocational high schools, issues have been raised regarding the lack of appropriate computer hardware specifications and the limited use of real networking devices. The media that have been used in teaching network operating systems have been based on virtualization-based simulation. However, such virtualization does not expose students to real hardware. This results in less than optimal hands-on activities and students’ psychomotor abilities. Consequently, alternative authentic media are needed to accommodate practical learning and improve psychomotor skills. The aim of this study is to explore the implementation of a single-board microcomputer in learning network operating systems. The Raspberry Pi was chosen as it can replace the role of a non-simulation PC. The choice of Raspberry Pi was also based on the fact that in Indonesia it is still rare to find its implementation for teaching and learning activities in vocational high school, so it is necessary to introduce the device to students. The operating system used by the Raspberry Pi is similar to Ubuntu, which is one of the network operating systems that must be mastered by vocational IT students. The research made a comparison between the two learning media as employed by two groups of students in different classes, one using virtualization-based simulation and the other using the Raspberry Pi. Based on the results, it is concluded that the use of the Raspberry Pi is more effective than that of virtualization-based simulation in improving students’ psychomotor and troubleshooting skills.
Highlights
Mastering a network operating system is one of the learning outcomes at Indonesian vocational high schools which have an information technology expertise programme
The most popular operating systems used in business are open-source ones, such as Ubuntu, Debian, and Centos, among others [1]. It is a challenge for vocational high schools to produce graduates who are skilled in mastering network operating systems
This study describes a method to solve problems in learning network operating systems through the application of a single-board microcomputer called the Raspberry Pi
Summary
Mastering a network operating system is one of the learning outcomes at Indonesian vocational high schools which have an information technology expertise programme. This sometimes causes problems on central operating systems that run important data for school or laboratory operations Another solution that has been implemented is the use of software to simulate the operating system through virtualization. Based on the observations, it was found that students were less enthusiastic about facing troubleshooting issues when configuring a network operating system in a virtual environment This is because they were not using real hardware, and the solutions offered by various sources or teaching materials were often irrelevant to the virtual simulation environment. The novelty of the research lies in the implementation of the device as a learning medium in network operating systems and laboratory work in a vocational high school. The activities shape students’ troubleshooting skills in the taught subject
