This research aimed at investigating whether or not the use of talking chips strategy can improve the speaking skill of Grade XI students. The researcher applied quasi-experimental research design. The sample of this research was XI IPA B as the experimental group (35 students) and XI IPA D as the control group (28 students) selected by employing purposive sampling technique. The technique of data collection was test (pretest and posttest). The Pretest was administered before treatment while the posttest was administered after the treatment. The treatment was given in eight meetings. The data were analyzed statistically in order to find out the significance of the students' speaking skill improvement. The mean score of the experimental group is 81.42. While the mean score of the control group is 74.91 andthe deviation score is 16.64 for the experimental group and 10.80 for the control group. By applying 0.05 level of significance and 60 degree of freedom (df) or 35+28 -2 = 61, it is found that the t-counted value (3.94) is higher than t-table value (2.00). In conclusion, the use of talking chips strategy can improve the speaking skill of Grade XI students.
