Abstract— The students in class X of SMAN 10 Banjarmasin has the low of learning outcome for geography study due to the low motivation of students. CTL approach uses to increase the motivation and to increase the learning outcomes of students. The objective of study is to improve the students learning outcomes of geography using the Contextual Teaching and Learning (CTL). This study uses a quasi-experimental using both pretest and posttest control group design. The population in this study is a class X at SMAN 10 in Banjarmasin. Sampling technique is cluster sampling technique. Samples of research is class X-3 as the experimental class with the number of respondent is 34 students and class X-2 as the control class with the number of respondent is 36 students. Primary data collection technique use observation and test methods. Data is analyzed using the percentage of enforceability, the calculation of the gain, and the t-test. The results of research shows that the percentage of CTL implementation is 83% or the excellent category. The result of the gain calculation shows that there is a very significant in the experimental class, tcount= 23.326. Gain calculation of control class is 10.721. The result of experimental class is greater than the control class. The result of the calculation of the t-test is tcount = 6.246, degree of freedom (df) = 68, ttable at 1% significance level = 2.39, and ttable at the 5% significance level = 1.67. tcount is greater than ttable at significant level of 1% and 5% (6.246> 2.39> 1.67). The result of calculation shows that there is a difference of geography learning outcomes both experiment class and control class. Geography learning outcome using CTL is better than a conventional method. Keywords— CTL, Learning Outcomes, Geography
