Quality Analysis of Test for Diagrams and Mathematical Representation Ability of High School Student in Physics Using Partial Credit Model

Abstract: In general, a test was developed based on classical test theory which had many weaknesses, therefore the test in this research was developed based on modern test theory (Item Response Theory). This study aimed to develop a Creative Thinking Skills test on physics lessons for Class X High School (PhysCreTHOTS) that eligible to be used based on modern test theory. This research was a development research using 4D model which involving 300 students of Class X High School in Gunung Kidul District of DIY. The scoring of test items using four categories of politomus scales and Partial Credit Model (PCM) techniques. The characteristics of the test consist of item match, reliability, difficulty level of item, information function and Standard Error of Measurement (SEM). The results showed that the instrument's reliability was 0.72. The entire test instrument is considered fit with PCM, with an INFIT MNSQ range of 0.93 to 1.10. The difficulty index of 63 items ranges from -1.06 to 1.04. Based on the information function and SEM it is known that the test instrument corresponds to the learner with a score of -1.8 to 3.0. The entire test is considered feasible to be used to measure Creative Thinking Skills in Physics lessons for high school X grade students.Keyword: creative thinking skills, partial credit model, polytomus, physics PENGEMBANGAN TES CREATIVE THINKING SKILLS FISIKA SMA (PhysCreTHOTS) BERDASARKAN TEORI TES MODERN Abstrak: Pada umumnya tes dikembangkan berdasarkan teori tes klasik yang banyak kelemahannya, maka tes yang dikembangkan ini dilakukan berdasarkan teori tes modern (Item Rseponse Theory). Penelitian bertujuan untuk mengembangkan tes Creative Thinking Skills fisika Kelas X SMA (PhysCreTHOTS) yang layak digunakan berdasarkan teori tes modern. Penelitian ini merupakan penelitian pengembangan menggunakan model 4D yang melibatkan 300 peserta didik Kelas X SMA di Kabupaten Gunung Kidul DIY. Penskoran item tes menggunakan skala politomus empat kategori dan menggunakan teknik Partial Credit Model (PCM). Karakteristik tes terdiri atas kecocokan item, reliabilitas, tingkat kesukaran item dan fungsi informasi dan Standard Error of Measurement (SEM). Hasil penelitian menyatakan bahwa realiabilitas instrumen sebesar 0,72. Keseluruhan instrumen tes dinyatakan fit dengan PCM, dengan rentang INFIT MNSQ 0,93 sampai 1,10. Indeks kesukaran 63 item (difficulty) antara -1,06 sampai 1,04. Berdasarkan fungsi informasi dan SEM diketahui bahwa instrumen tes sesuai dengan peserta didik berkemampuan dari -1,8 sampai 3,0. Keseluruhan tes dinyatakan layak digunakan untuk mengukur Creative Thinking Skills Fisika peserta didik kelas X SMA.Kata kunci : creative thinking skills, partial credit model, politomus, fisika

Penelitian ini bertujuan mengembangkan instrumen penilaian kinerja kemampuan inkuiri mata pelajaran fisika peserta didik SMA. Instrumen terdiri atas empat paket perangkat tes yang masing-masing terdiri atas 30 butir tes termasuk 9 butir bersama yang telah divalidasi oleh ahli pendidikan fisika, ahli fisika, ahli pengukuran, dan praktisi. Instrumen diujicobakan pada 2015 peserta didik. Model respon butir politomus empat kategori digunakan untuk menganalisis data hasil uji coba menurut Partial Credit Model (PCM). Hasil penelitian menunjukkan bahwa, berdasarkan kriteria batas terendah dan tertinggi mean INFIT MNSQ, yaitu 0,77 dan 1,30 butir tes semuanya fit dengan model PCM. Tingkat kesulitan butir-butir tes berada pada rentang antara -0,83 sampai +0,84 yang berarti butir-butir tes dalam kategori baik karena nilainya di antara -2,0 dan +2,0. Fungsi informasi total tes relatif tinggi untuk kemampuan antara -2,5 sampai +2,5. Dengan demikian, instrumen yang dikembangkan dapat digunakan untuk meng-ukur kemampuan inkuiri mata pelajaran fisika siswa SMA. Hasil pengukuran menunjukkan bahwa kemampuan inkuiri peserta didik pada mata pelajaran fisika SMA di DIY berada di atas kemampuan rata-rata.Kata kunci: kemampuan inkuiri, mata pelajaran fisika SMA, Penilaian kinerja.______________________________________________________________ DEVELOPING ASSESSMENT INSTRUMENT OF THE PERFORMANCE OF THE INQUIRY ABILITIES IN PHYSICS SUBJECT OF HIGH SCHOOL STUDENTSAbstract The research was to develop an assessment instrument of performance for the inquiry ability of physic subject of senior high school students. The instrument consisted of four package sets of test and each of the sets consisted of 30 test items, including 9 items that had been validated by the expert of physic education, the expert of physic, the expert of measurement and the practitioner. The instrument was tested to 2,015 learning participants. The four-category politomous item response model was implemented for the data analysis of the experiment results according to the Partial Credit Model (PCM). The results of the research showed that based on the criteria of the lowest benchmark and the highest benchmark of mean INFIT MNSQ, was 0.77 and 1.30, all of the test items had been fit with the PCM model. The difficulty level of the test items was between -0.83 and +0,84 which implied that the test items belonged to the good category because the value of the test items was between -2.0 and +2.0. The informative function of the total tests was relatively high for ability between -2.5 to +2.5. Thereby, the instrument developed can be used for measuring the inquiry ability of the physic subject of the senior high school students. The results of measurement showed that the inquiry ability of the learning participants in physic subject within the senior high schools in DIY was above average.
