摘要：This study aims to determine the effect of the National Instruments (NI) Multisim Software on students’ mastery of the wave rectifier circuit viewed from students' visual-spatial abilities (KVS). A pre-experimental design was used in this study. The sample of this research was students of the Physics Education Study Program taking the Basic Electronics I course selected through saturated sampling technique. The data collection tools were in the form of a visual-spatial ability test instrument and the wave rectifier circuit mastery test instrument. Correlation tests, multiple regression, and independent-sample t-test were used to determine the effect of spatial-visual ability on the learning outcomes of the wave rectifier circuit through the application of the National Instruments Multisim Software. The results obtained indicate that: 1) Student learning outcomes on the wave rectifier circuit material by using the NI-Multisim Software has in the sufficient category; 2) Students' visual-spatial ability on the KVS-interpretation has very high-category, KVS-series pattern has high-category, KVS-reflection has high-category, KVS-rotation has high-category, KVS-projection has high-category, and KVS-drawing has medium-category; 3) The ability of students' spatial visibility has a positive and significant correlation to student learning outcomes and has an influence contribution of 76.20% to learning outcomes; 4) The learning outcomes of students who have KVS-high are better than the average learning outcomes of students who have KVS-low in learning the wave rectifier series material using the NI-Multisim software.
