Abstract
Focusing on electrical circuits as the topic for a STEM project, this research aims to develop virtual reality media for student learning. Using virtual reality media to perform STEM electrical circuit activities, data was collected and analyzed. The virtual reality media was then evaluated by five experts who used the Index of Item-Objective Congruence (IOC) to assess its effectiveness, where the IOC for each criteria was 0.8 or higher. Moreover, after evaluating it with the Diffusion of Innovation Theory (DOI), the arithmetic mean of its effectiveness on the diffusion of innovation was 4.32, with a 0.48 standard deviation. This demonstrates that the use of virtual reality media was a beneficial innovation at a high level. Afterwards, the developed virtual reality media was evaluated by a sample of 30 subjects in the areas of VR features, usability, learning experience, and VR measurement outcomes. The findings show that its arithmetic mean was 4.67 with a 0.47 standard deviation, meaning the developed virtual reality media was an effective for electrical circuit learning at the highest level. Furthermore, after evaluating its effectiveness in the area of information technology acceptance, it was found that, for these criteria, the arithmetic mean was 4.64 with a standard deviation of 0.48. This indicates that the subjects generally accepted the use of virtual reality media for use in learning STEM activities at the highest level. It can be said that the development of the virtual reality media for learning STEM activities with a focus on electrical circuits enhances the learning process of the learners who confirmed such statements at the highest level, with an increase in subject understanding of the learning activity and self-satisfaction, while at the same time reducing the prejudice learners have towards the study of electrical circuit installation.

The virtual reality content, for learning STEM electrical circuit activities, the results of which are based on the Index of Item-Objective Congruence (IOC) [5], [7], [18] shows that after developing the virtual reality and assessing its congruence by five experts, the media was rated with 0.8 or higher for each criterion
This paper presents the development of the virtual reality simulation media for learning STEM electrical circuit activities consisted of the learning of series electrical circuit installations to enable the design and development of appropriate virtual reality media
Summary
The study of electrical circuits is the basis of contemporary technology which requires a basic knowledge and understanding of electricity. This is a requirement in the electronic equipment and electronic devices assembly industries. Learners must use their imagination and electronic laboratories to support their studies and develop their comprehension. The learners must be crucially careful as there are dangers associated with working with electrical components and appliances, some of which can be lethal. Electronic laboratories normally require expensive experimental instruments and other equipment, so it is important to maintain a high level of safety and spend huge budgets on the preparation of electrical circuit-intensive materials and equipment for learning. The pictures shown in textbooks, websites, social media, etc., tend to provide the learner with a degraded experience when compared to hands-on activities
