Virtual Laboratory Application of Direct Current Electric Motor: An Expert-Based Evaluation

This research aims to validate the virtual laboratory application of a direct current motor based on expert judgment. There are two aspects of the assessment. The first is the electrical machine content aspect, and the second is the computer-based media content aspect. The instrument was developed based on scientific studies related to multimedia quality criteria. The instrument was declared valid through a content validity test and evaluation by an evaluation expert. Evaluating the virtual laboratory application media was conducted by two groups of experts: the material content expert in electrical machinery and the computer-based media content expert. The assessment results showed that the virtual laboratory application media was declared Very Appropriate for all dimensions of the assessment of material and media content.
