THE ENHANCEMENT OF CONSISTENCY OF INTERPRETATION SKILLS ON THE NEWTON’S LAWS CONCEPT Yudi Kurniawan 1) 1) STKIP Singkawang, Singkawang, Indonesia E-mail: yudikurniawan1012@gmail.com Abstract. Conceptual understanding is the most important thing that students should have rather than they had reaches achievement. The interpretation skill is one of conceptual understanding aspects. The aim of this paper is to know the consistency of students’ interpreting skills and all at once to get the levels of increasing of students’ interpretations skill. These variables learned by Interactive Lecture Demonstrations (ILD) common sense. The method of this research is pre-experimental research with one group pretest- posttest design. The sample has taken by cluster random sampling. The result had shown that 16 % of all student that are have perfect consistency of interpretation skill and there are increasing of interpretation skill on 84 % from unknown to be understand (this skill). This finding could be used by the future researcher to study in the other areas of conceptual understanding aspects. Keywords: Consistency; Interpretation Skill; Newton’s Laws I. INTRODUCTION Physics is a kind of the way to observe a phenomenon either directly or through experiment. The conceptual understanding process in physics learning is more important than achievement in result. Understanding must be obtained through the learning process because students have knowledge before get the new information in the classroom. The learning process in physics have designed to assist all of student, to assist students’ difficulties to understand the concept while they were studying in the class [1] [2]. In an effort to more understand the knowledge that derived from initial ideas before learning and learning experiences, that should it has an approach or method that provides every contextual problem. In the end, its benefits to engage students in responsible for their own learning and more questions than to accept a spontaneous statement. Therefore, students who are considered to have good conceptual understanding are the ability to explain many natural phenomena and arrange them in common terms, in different context [3] [4]. This statement became a basics argument that the consistency in the scientific concept is very important. Students has able to re-write their understanding to another form/ sentence in the same define, as like as scientific conception. If they are able to pass this phase, they are would get deep conceptual understanding [5] [6]. To facilitate an excellence understanding in their class, a teacher at various levels of education should be able to apply the learning process with student-centered approach. Student- centered learning can provide to students with “natural” experience in physics learning and can improve students' conceptual understanding [6] [7]. Therefore, it impossible to enhance student’s cognitive level without applying an innovative teaching method or learning models. There is one of various innovative learning models that it can support the conceptual understanding and it called as Interactive Lecture Demonstrations (ILD). The adaptation of ILD versions of Sokoloff and Thornton is a common sense oriented ILD (CS) based on everyday experience. This model able to overview of scientific concepts either directly and virtually so that learned concepts can be demonstrated and student could observe it. The virtual concept (ex. in this study: Newtons 1 st Laws) most of them became easier to understand after they saw the video or virtual simulation [8]. Demonstrations in ILD can generate student motivation to be more active in observing the phenomena associated with solving daily individual problems [9]. In this study, the concept that tested are Newton's Law. This is because Newton's Laws concept are basics concepts in physics learning at the elementary, secondary schools or college level. The Newton Law always related to force and motion and as we know, those concepts are taught in the all levels of education [10] [11] [12]. Based on the background, this research is going to get data of the consistency of interpretation skill in Newton Laws concept through implementation of ILD common sense oriented. Its imply to get description the number of student that enhance their interpretation skill after treatment.
