<![CDATA[Learning is an activity involving teachers and students. The success of teaching and learning process are influenced by student learning motivation. The existence of student learning motivation will give spirit and learning becomes more focused for students. Building intrinsic motivation in students will be better than extrinsic motivation. By students' intrinsic motivation to learn because of the sincerity of their hearts, the positive results of learning efforts that will shown. However, extrinsic motivation also determines the interest of students in learning. When students have a desire to learn but the extrinsic factors do not support, the student will lose his spirits. Both intrinsic and extrinsic factors can determine the success of students in the learning process. Motivation is an energy change within the person characterized by effective arausal and antisipatory goal reaction. Motivation will push, move and direct students to learn. Students who have a high learning motivation will do activities in acquiring knowledge. Motivation will arouse the interest of students to learn. Motivation has the function of which is to (1) encourage students to move in order to get maximum results, and (2) as referring to carry out activities in achieving the objectives specific objectives. Motivation has traits include: resilient in the face of adversity, diligently not easily bored and others. The existence of the learning motivation greatly affected the success of the learning process. Students can reach a good study achievements on him when there is motivation to learn. Therefore the motivation has a very important position in learning.]]>

<![CDATA[The instructional strategy applied in learning and appropriate subject matter of Chemistry taught will be able to provide convenience for students in understanding the subject matter of Chemistry, so that learning experience will be more meaningful for students. One of the existing learning strategies is metacognition which is the students' knowledge related to their weaknesses and strengths in learning and self-regulation during learning activities such as planning, process arrangement, evaluation, commitment, minimization, procedure and conditioning. Students who have various dimensions of high metacognition will try to learn various ways to make it easy for them that learning activities are easy and fun to achieve high learning results. Thus, there is a correlation between the metacognition of students in learning with efforts to improve student learning outcomes in Chemistry subjects. The increasing of appliying various dimensions of students metacognition in learning will have an impact on improving student learning outcomes in Chemistry subjects. In the fact, the student who use / apply their metacogical dimensions in learning Chemistry subjects, students will be happy, eager and easy in learning Chemistry subjects, able to assess and predict their ability in learning Chemistry subjects process that ultimately students can achieve high learning outcomes in Chemistry subjects.]]>
