PENGEMBANGAN TES KEMAMPUAN BERPIKIR TINGKAT TINGGI FISIKA (PysTHOTS) PESERTA DIDIK SMA

Abstract

Penelitian dilakukan untuk mengembangkan instrumen kemampuan berpikir tingkat tinggi fisika (PhysTHOTS) peserta didik SMA dan mendapatkan karakteristik PhysTHOTS. Kisi-kisi instrumen disusun berdasarkan aspek dan subaspek kemampuan berpikir tingkat tinggi, yang selanjutnya digunakan untuk menyusun item-item. Instrumen terdiri atas dua perangkat tes yang masing-masing memiliki 26 item termasuk delapan anchor item dan telah divalidasi oleh ahli pengukuran, ahli pendidikan fisika, ahli fisika, dan praktisi. Instrumen yang telah divalidasi diujicobakan pada 1.001 siswa dari sepuluh SMAN di Daerah Istimewa Yogyakarta. Data politomus dianalisis menggunakan Partial Credit Model (PCM). Hasil uji coba menunjukkan bahwa semua item sebanyak 44 dan instrumen PhysTHOTS terbukti fit dengan PCM, reliabilitas instrumen sebesar 0,95, indeks kesukaran item mulai -0,86 sampai 1,06 yang berarti semua item dalam kategori baik. Dengan demikian, PhysTHOTS memenuhi syarat digunakan untuk mengukur kemampuan berpikir tingkat tinggi fisika peserta didik SMA.

Kata kunci: pengembangan instrumen, tes kemampuan berpikir tingkat tinggi, fisika, politomus, dan PCM

DEVELOPING HIGHER ORDER THINKING SKILL TEST OF PHYSICS (PhysTHOTS) FOR SENIOR HIGH SCHOOL STUDENTS

Abstrak The objectives of this research were to develop an instrument for measuring senior high school students’ physics higher order thinking skills (PhysTHOTS) and to obtain the characteristics of the PhysHOTS. The instrument blue print was developed based on the aspects and sub-aspects of high order thinking skills, then it was used to develop the items. Two sets of instrument consisting of 26 items and each, including eight anchor items were then validated by promotors, measurement experts, physics specialists, physics education experts, and practitioners. The validated instruments were then tried out on 1,001 students of ten senior high schools throughout Special Province of Yogyakarta. The polytomous data were analyzed according to the Partial Credit Model (PCM). The results show that the 44 items and PhysTHOTS were fit to the PCM,  the reliability of the test  was 0.95, the items’ difficulty indexes were between -0.86 and 1.06. Therefore, the PhysTHOTS are qualified to measure senior high school students’ physics higher order thinking skills.
