The improvement of student skill can be seen from the improvement in test of cycles 1 and 2 compared with that before research. The indicators of student skill variable: readiness, guided movement, complex movement and creativity. In prior condition, 29% students passed successfully in readiness, 32% in guided movement, 11% in complex movement, and 0% in creativity. In cycle 1, the 89% students passed successfully in readiness, 89% in guided movement, 71% in complex movement, and 64% in creativity. In cycle 2, 100% students passed successfully in readiness, 100% in guided movement, 86% in complex movement, and 93% in creativity. The hypothesis of research was supported, namely the skill of operating Ms Excel in spreadsheet subject could improve through the use of peer teaching learning method.Keywords: readiness, guided movement, complex movement, creativity]]>
