The specific problem in this research lies on the diversity of students in one public elementary school in Cimahi City, situated in the area of the Indonesian Army. Therefore, this research seeks to investigate the difference in improvement of students' cross cultural skills between learning using VBA (Visual Basic of Application)-based Monopoly game teaching materials in Microsoft Excel and conventional learning. This research aims at improving students' cross cultural skills, and observing the differences or disconnection of the improvement of students' cultural skills between learning using VBA-based teaching materials and conventional learning.
