The use of learning methods is very important to achieve that comprehension. Students fail to understand physics concepts generally caused by learning process that not allowing students to find the concept by him or hers self. Therefore the concept gathered from learning process would lose from cognitive structure [1]. In order to understand physics concepts, learning process must allowing students to find concept directly by their self through learning activities. One of learning models that can be used to solve the problem above is implementing inquiry learning model [2]. There are several activities in inquiry learning model as observing, measuring, classify, asking, defining hypothesis, planning experiment, processing data, and communicating information by learner under guidance of teacher [3]. Through those activities, students allowed to find concept directly and to train their science process and science performance skills. Science performance and science process are the important thing have to be owned by students especially physics teacher candidate [4][5]. Because these skills would be implemented in learning process by student (teacher candidate) when they graduate and work as physics teacher. This is in line with Badan Nasional Standar Pendidikan (BNSP) Indonesia that emphasized implementation of inquiry learning in learning process [6]. Therefore the college that produce physics teachers like STKIP Soe have to trains students skills in science process and science performance. Several studies have been done in training and enhancing students science performance skills [1][7][8][9]. These studies or research reported that there are increasing on students science performance skills after conducting inquiry learning process. These research also reported the important of using of learning tools or material design in inquiry learning to develop students skills on science performance. Light polarization is an abstract concept in physics. This concept would be difficult to understand by student if learned without using tools or media [10]. Light polarization can be demonstrated using polarizer and light detector. Those apparatus can be found in our laboratory, but not equipped with light detector. So student only do demonstration without getting quantitative data. The solution to that problem is to make a learning tool that equipped with light detector using electronic devices that easily and cheap to found. Those electronic devices are Arduino and photodiode. Arduino is a microcontroller that can be used as microprocessor to read analog data. Photodiode is a light sensor that can be used to detect intensity of light. The two devices can be used to design a learning tool of light polarization that can measure and display the data of light intensity digitally. Based on background stated above, the problem statement in this research is: 1) How to design and develop a light polarization learning tool based on Arduino and science performance? 2) How to validate the light polarization learning tool? 3) Is the light polarization learning tool effective to raise student science performance? 4) Is the light polarization learning tool feasible to use in learning process? 2. Literature Review 2.1 Science Performance Science performance is an activity conducted according to scientific rules. The steps of science performance are defining problems, defining hypothesis, examining hypothesis, interpreting data, and draw conclusion [11]. Suparno (2006) stated that science performance in physics is observing, questioning, defining hypothesis, planning experiment to evaluate the hypothesis, drawing conclusion based on experiment results. In this research, subject of science performance of students observed are defining hypothesis, identifying variable, planning experiment, getting data, drawing conclusion and communicating data or Paper ID: ART20193270 10.21275/ART20193270 156
