Student Teams Achievement Division (STAD) through guided inquiry approach to improving student result class XI IPA SMAN 3 Halmahera Utara in subject chemical equilibrium. The population in this study were students of class XI IPA SMAN 3 Halmahera Utara totaling 45 students spread on two classes. The technique used to determine the sample was saturated sampling technique in which all members of the study population sampled. The research data were analyzed using Anacova test to determine student learning outcomes. Based on the analysis of data there are significant cooperative learning model Student Teams Achievement Division (STAD) through guided inquiry approach to improving student learning outcomes class XI IPA SMAN 3 Halmahera Utara in chemical equilibrium with the material test results Anacova where t account = 2.60> t table = 1.681 with a huge influence, namely the increase in 87 %. In the affective aspect of student learning results obtained for the experimental class of 86% and 76% control class. As for the psychomotor aspects of student learning results obtained by 84% the experimental class and control class was 68%. Copy Right, IJAR, 2017,.

Introduction:- Success in learning can be determined by the amount of students’ participation in following the learning process, the more active students take part in learning activities, the more successful the learning process. The fact that in the process of learning in class most of the students are less active, where the cause is learning still occurs conventionally that makes students lazy and lose motivation to learn. Similarly, teachers will have difficulty in teaching because of lack of students’ motivation duri ng the learning process. One of the materials that is considered difficult is the chemical equilibrium material, especially on the factors that influence the direction of equilibrium shift and at the price determination of equilibrium constants. Therefore, it needs effort from teacher in teaching to apply the right model, approach, and method so that student become active and have spirit in learning. The above problem can be overcome by using cooperative learning model of Student Teams Achievement Division (STAD) type. This model is a fun and innovative learning model because students learn together in a group so that students will be more motivated and enthusiastic to learn. STAD type cooperative model is good for chemical equilibrium material because there are counts then inter-group cooperation is needed in understanding chemical equilibrium material through guided inquiry approach.
